The Kruskal-Wallis test was used to assess the differences in the scores between both groups on endourological techniques. A Likert scale (1-5) was used to grade the participants’ answers to the post-course 12-month survey.

Trainees from UK scored significantly higher in the pre-course MCQ assessment, however after completion of the boot camp, no significant difference was noted. There were no differences between the groups at e-BLUS completion times, and both groups significantly improved their results. A 12-month post-course survey on the utility of training during the boot camp and qualitative evaluation of the course by overseas delegates was very positive.

The USBC is a valuable learning experience that leads to improvement of technical and soft skills of UK and non-UK trainees alike.

During the last decade a paradigm shift was invoked when the results from The Cancer Genome Atlas (TCGA) project were published. Comprehensive genomic profiling data from TCGA has shown that there are four molecular subgroups of endometrioid carcinomas instead of the two subtypes proposed by Bokhman in the 1970s. For ovarian carcinomas (OC) it is now evident that molecular parameters are also significant. Although traditionally referred to as a single entity, OC is not a homogeneous disease but rather a group of diseases, each with different morphology and biologic behavior. Similar to endometrial cancers, advanced cervical cancer and recurrent disease remain particularly problematic due to chemotherapy resistance. Effective prophylactic vaccines against the most important carcinogenic human papillomaviruses (HPV) types are available, but uptake remains poor. The E6 and E7 oncoproteins are attractive targets for cancer therapy. They are constitutively expressed in HPV-positive tumors, specific to the tumor, functionally important to the tumor cells and recognized by the adaptive immune system as tumor antigens. This review summarizes recent advances in the molecular pathology, which have greatly improved our understanding of the biology of gynecologic cancers.Immunization is an important component of preventive healthcare services. By recognizing and understanding factors associated with suboptimal vaccination compliance, healthcare providers can better approach at-risk populations and target efforts at reinforcing the vital importance of immunizations. The objective of this study was to understand the factors associated with adherence, beliefs and behaviors of influenza, pneumococcal, and herpes zoster vaccines receipt among commercially insured adults. A cross-sectional survey of patients with medical and pharmacy benefits for a 24-month period between August 1, 2014 and July 31, 2016 who were eligible to receive at least one of three adult vaccines (influenza, pneumococcal, and herpes zoster) was completed. Patients were identified as eligible to receive a vaccine based on current guidelines from the CDC ACIP. Health plan members were identified from administrative claims data in the HealthCore Integrated Research DatabaseSM (HIRD). Among the participants, 11% were eligible and up-to-date on all three vaccines; 52% on some and 37% were not up-to-date on any of the three vaccines. Participants with a healthcare provider were more likely to be up-to-date on eligible vaccines 79.9% for none, 91.3% for some, and 97.8% for all eligible vaccines. The composite Vaccine Myth Belief score was significantly associated with being up to date on eligible vaccines 45.0%/12.8% for none, 12/5%/30.8% for some, and 8.9%/33.3% for those up-to-date on all eligible vaccines. Despite numerous interventions designed to increase vaccination rates among adults, compliance remains suboptimal. It is evident that patient and provider education is necessary to fill knowledge gaps and misunderstandings; however knowledge by itself is not sufficient to improve immunization practices. Our results highlight a population that could benefit from a multidisciplinary approach, including interventions at the individual and health system levels.The influenza virus neuraminidase (NA) plays an integral role in the influenza virus life cycle through the release of virions from infected cells. NA-specific antibodies can impede virus replication by binding to the NA and blocking its enzymatic activity, providing significant protection from influenza-associated morbidity and mortality. NA included in current seasonal influenza virus vaccines exhibits low immunogenicity, potentially caused by compromised antigenic integrity during vaccine production. To determine how certain types of „stress” could influence the antigenicity of NA we performed a series of in vitro experiments where we treated NA with formalin, EDTA or heat and measured the impact of these treatments on NA enzymatic activity and structural integrity. We found that increasing concentrations of formalin or EDTA and increasing temperature abolished the enzymatic activity of both H1N1, H3N2, and influenza B purified viruses and recombinant NA proteins. However, formalin and EDTA treatment did not drastically affect conformational epitopes found on the NA, whereas heat treatment abolished conformational epitopes. We next performed a vaccination experiment, where mice were vaccinated with recombinant N2 NA treated with 0.3% formalin or 0.125 M EDTA (which both inactivated NA activity) were protected from virus challenge while animals vaccinated with heat treated NA were not. We next tested the protective effect of monomeric (no enzymatic activity) versus tetrameric (highly active) N1 NA. Again, only the tetrameric form protected mice from challenge while the monomeric form did not. Together, our data demonstrate that enzymatically active NA is not required to induce protective antibody responses as a vaccine, however a correctly folded NA is essential.Addressing vaccine management bottlenecks, including high vaccine wastage rates, has traditionally been addressed through health worker training and other didactic methods of technical assistance or support as required. It has been shown, though, that the high level of technical skills, expertise, and responsibility required in vaccine handling and management cannot be achieved by mere didactic learning. While gains have been made in vaccine management and handling with these approaches, there remain challenges of high vaccine wastage rates and poor vaccine management practices across the board. Interestingly, approaching vaccine management through social behavior change has not been documented. Through Participatory Action Research (PAR), which is increasingly being used in health sciences, we explore an attempt at strengthening vaccine management and thus reducing high vaccine wastage rates by working together with health workers to identify plausible, realistic solutions to vaccine management through social behavior change. Select health workers directly involved with the immunization program in the four major provinces of the Solomon Islands were identified purposively to use action media and come up with concepts and materials for social behavior change communication that will have an impact on effective vaccine management and reducing wastages. This is the first documented use of such methodology in addressing vaccine management issues.

COVID-19 pandemic has affected routine immunization globally. Impact will likely be higher in low and middle-income countries with limited healthcare resources and fragile health systems. We quantified the impact, spatial heterogeneity, and determinants for childhood immunizations of 48 million population affected in the Sindh province of Pakistan.

We extracted individual immunization records from real-time provincial Electronic Immunization Registry from September 23, 2019, to July 11, 2020. Comparing baseline (6months preceding the lockdown) and the COVID-19 lockdown period, we analyzed the impact on daily immunization coverage rate for each antigen by geographical area. We used multivariable logistic regression to explore the predictors associated with immunizations during the lockdown.

There was a 52.5% decline in the daily average total number of vaccinations administered during lockdown compared to baseline. The highest decline was seen for Bacille Cal-mette Guérin (BCG) (40.6% (958/2360) immunizaassociation with immunization uptake, even during a challenging lockdown.

One out of every two children in Sindh province has missed their routine vaccinations during the provincial COVID-19 lockdown. The pool of un-immunized children is expanding during lockdown, leaving them susceptible to vaccine-preventable diseases. There is a need for tailored interventions to promote immunization visits and safe service delivery. Higher maternal education, facility-based births, and early enrollment into the immunization program continue to show a positive association with immunization uptake, even during a challenging lockdown.

Brucella abortus S19 is the most widely used vaccine for the prevention of bovine brucellosis which remains the reference vaccine to which many other vaccine/s are compared. Considering the larger vaccination coverage by reduced dose of vaccine, the study aimed to compare reduced graded doses (1/10th, 1/20th and 1/100th) with standard dose of S19 vaccine (40×10

CFU /dose) to determine the effective immunizing dose in water buffaloes.

A total of 25 female buffalo calves (Bubalus bubalis) in the age group of 4-5months were equally grouped into five animals each in four test and one control groups and given with specified vaccine dose. The blood samples were collected on post vaccination days 14, 28, 45, 60, 90 and 120 for assessing innate (TNF-α and IL-12), humoral (IgG antibodies against Brucella LPS) and cell mediated immune responses (IFN-γ, CD4+and CD8+counts).

The full dose, 1/10th and 1/20th reduced doses of S19 vaccine was capable of eliciting pathogen-specific antibody response, vaccine induced secretion of IL-12, TNF-α and IFN-γ with CD4+and CD8+effector T cell responses. Persistence of antibody and magnitude of immune responses were found dose dependent.

Comparable immune responses were noticed with 1/10th reduced dose similar to standard dose. With this observation, decline of antibody titre will reduce the number of false positives and reduced dose of vaccine will facilitate larger vaccination coverage in the country.

Comparable immune responses were noticed with 1/10th reduced dose similar to standard dose. With this observation, decline of antibody titre will reduce the number of false positives and reduced dose of vaccine will facilitate larger vaccination coverage in the country.

The Region of the Americas has a long history of implementing maternal and neonatal immunization (MNI) programs. Our study aimed to understand the state of MNI policies, strategies and implementation practices in Latin America (LA).

Study conducted in 5 middle-income countries Argentina, Brazil, Honduras, Mexico and Peru. The methods included a desk review, interviews with national stakeholders and health care providers, focus groups with pregnant women and observations in health facilities. Enablers and barriers were identified and categorized as individual, societal or related to the health system.

All 5 participating countries had similar MNI policies and high access to antenatal care. Key enablers were the high acceptability of vaccination during pregnancy, high-level of political will and a national legal framework ensuring free access to vaccines. At the health system level, implementation was facilitated by the existence of immunization advisory committees, a pooled vaccine procurement mechanism,lso improve equitable access to health services and prepare for the introduction of future vaccines for pregnant women.

Middle-income countries in LA have successfully implemented MNI programs and several enablers were identified. To overcome remaining barriers, there is a need to focus on improving the „immunization journey” for pregnant women through providing more clear and timely information to users and providers; removing barriers to access; ensuring adequate supply, human resources and infrastructure; making the health service experience positive; and establishing integrated information systems that allow for monitoring the progress toward achieving MNI goals. Strengthening the MNI programs can also improve equitable access to health services and prepare for the introduction of future vaccines for pregnant women.Active surveillance (AS) is an accepted management strategy for some patients with renal cell carcinoma, but limited tools are available to identify optimal AS candidates. While renal mass biopsy provides diagnostic information, risk stratification based on biopsy is limited. In a retrospective, multi-institutional cohort that underwent renal mass biopsy followed by surgery, we assessed the ability of the cell cycle proliferation (CCP) score from clinical biopsy specimens to predict adverse surgical pathology (ie, grade 3-4, pT stage ≥3, metastasis at surgery, or papillary type II). Of 202 patients, 98 (49%) had adverse surgical pathology. When added to a baseline model including age, sex, race, lesion size, biopsy grade, and histology, CCP score was significantly associated with adverse pathology when modeled as a binary (odds ratio [OR] 2.44 for CCP score >0, p = 0.02) and a continuous (OR 1.72 per one unit increase, p = 0.04) variable. Discriminative performance measured by the area under the curve (AUC) improved from 0.73 in the baseline model to 0.75 and 0.76 in models including the CCP score. In the subgroup of patients with nephrectomy CCP score available (n = 67), the biopsy-based model outperformed the nephrectomy-based model (AUC 0.78 vs 0.75). These data support prospective assessment of biopsy CCP score to confirm clinical validity and assess potential utility in AS-eligible patients. PATIENT SUMMARY In patients with localized renal cell carcinoma who underwent renal mass biopsy followed by surgery, the cell cycle proliferation score from clinical biopsy specimens could predict adverse surgical pathology.

The feasibility and efficacy of robot-assisted radical prostatectomy (RARP) in locally advanced prostate cancer (PCa) patients with iT3 lesion at magnetic resonance imaging (MRI) are currently not explored.

To describe our revised RARP technique (ie, superextended RARP [SE-RARP]) for PCa patients with posterior iT3a or iT3b at MRI.

Data from 89 patients with posterior iT3a or T3b disease who underwent SE-RARP at a single high-volume centre between 2015 and 2018 were analysed.

RARP was performed using a DaVinci Xi system. The surgical approach provided an inter- or extrafascial RARP where Denonvilliers’ fascia and perirectal fat were dissected free and left on the posterior surface of the seminal vesicles.

Perioperative outcomes, and intra- and postoperative complications were assessed. Postoperative outcomes were assessed in patients with complete follow-up data (n = 78). Biochemical recurrence (BCR) was defined as two consecutive prostate-specific antigen values of ≥0.2 ng/ml. Urinary continence (Uque applicable to patients with posterior iT3a or iT3b at preoperative MRI. This technique is associated with good morbidity and continence recovery rates, and might guarantee biochemical control of the disease and postpone the use of additional treatments in patients with low-grade and negative surgical margins.

A revised robot-assisted radical prostatectomy technique applicable to prostate cancer patients with posterior iT3a or iT3b lesion at magnetic resonance imaging was described. This novel technique is feasible and safe in expert hands.

Eosinophilic otitis media (EOM) is an intractable otitis media mostly associated with bronchial asthma. Dupilumab, an anti-interleukin (IL)-4 receptor (R)α, is effective and has been approved for use in patients with moderate to severe bronchial asthma, atopic dermatitis and chronic rhinosinusitis with nasal polyposis, whose diseases are not controlled by previous treatments including other molecular targeted drugs. We aimed to assess efficacy of dupilumab in three EOM patients with associated bronchial asthma, who were poor responders to previous topical and systemic corticosteroid therapy and molecular targeted therapies.

Three patients with severe, refractory EOM (two with a granulation type) associated with bronchial asthma received dupilumab as add-on therapy for at least 6 months. The efficacy of dupilumab therapy was evaluated using severity scores, symptom scores, hearing acuities, temporal bone computed tomography (CT) scores, and surrogate markers before and after therapy.

Severity scores in all patients were dramatically reduced to 2 points or less (full score 16 points) after initiation of therapy. Air conduction hearing levels were improved in all patients. Temporal bone CT scores in two patients were reduced, and serum IgE levels in all three patients also decreased following therapy.

We provide the first report that add-on dupilumab therapy was effective in patients with severe, refractory EOM who did not respond to the treatments including other molecular targeted therapy. Patients with severe middle ear mucosal change may benefit particularly from dupilumab therapy.

Its most frequent form of presentation at the ophthalmological level is retinitis pigmentosa, and in some cases the ophthalmologist could be the first one to alert the other paediatric specialties to carry out a multidisciplinary approach to the case. The case is presented of a patient with long-chain 3-hydroxyacyl-CoA dehydrogenase deficit detected in neonatal screening, and which clinically debuted as pigmentary retinosis with no alteration in visual acuity as observed in the fundus images and optical coherence tomography of the retina provided. Finally, a review of the literature of this potentially lethal pathology is presented, and the main pathological and clinical features are highlighted.Scuba diving can be practiced recreationally or professionally. In both modalities the diver can be exposed to risks such as decompression syndrome and thus, the use of a hyperbaric chamber, hyper-oxygenation of the gas cylinder, barotrauma, and immersion in closed circuits. These situations have some phenomena in common, such as the great pressure differences, which can cause a wide range of alterations, including ophthalmological ones. The development of index myopia and nuclear cataract are ocular findings frequently associated with increased oxygen pressure. In this context, an imbalance is established between oxidative species and antioxidant defences, such as glutathione, which has a key role in maintaining the transparency of the lens. The cases are presented of 2 young coral fisher patients, who had recently developed a progressive myopisation associated with nuclear cataracts.

Healthcare providers’ (HCPs) perceptions of smokers’ responsibility for smoking may affect implementation of smoking cessation care (SCC), but are understudied. This study examined Dutch HCPs’ perceptions of smokers’ responsibility for smoking, and how many and which subgroups exist with regard to these perceptions.

Observational cross-sectional study among physicians and other HCPs (N = 570). Latent class analysis was used to analyse data.

Results showed two latent classes of HCPs a majority (77 %) that appeared to hold smokers themselves more accountable for their smoking, and a minority (23 %) that seemed more inclined to believe that people smoked as a consequence of factors such as addiction, and smoking initiation when people were young and could not foresee consequences. The two-class model showed excellent certainty in classification. Class membership was associated with age, working experience, and smoking status. The majority class experienced more barriers to SCC than the minority class and provided SCC tasks to fewer patients.

HCPs’ perceptions of smokers’ responsibility for smoking relate to HCP background characteristics, barriers to SCC and implementation of SCC.

New approaches to improving SCC might be needed that take HCP’s perceptions of smokers’ responsibility into account.

We find in the constitutional text itself the attribution to the public powers of the competence to organize and protect public health (art. 43 CE), therefore public powers are able to regulate by law the duties and obligations of citizens «in cases of serious risk, catastrophe or public calamity» (art. 32(4) CE). Moreover, we study the Spanish legal framework on public health, including the General Sanitary Law, the General Public Health Law, with a special attention to the art. 3 of Organic Law 3/1986, 14 April, on special measures in the field of public health, which attributes to the health authorities a huge competence to be able to adopt, in a situation of sanitary crisis such as the current one, decisions that, with the necessary guarantees, suppose a restriction or limitation of rights, including fundamental ones as in the case of confinement. These limitations on fundamental rights require a judicial authorization or ratification. However, we also consider the convenience of a new organic law to regulate in detail the procedure and the legal guarantees to carry out the adoption and development of these measures.

Oral Nutritional Supplements (ONS) are used to treat malnutrition and improve clinical outcomes in malnourished patients. Poor handgrip strength (HGS) is associated with an increased risk of mortality, disability and other adverse health consequences. This analysis examined the effect of a specialized ONS on HGS and its relationship to nutritional status in hospitalized, older adults with malnutrition who were participants in the NOURISH trial.

We enrolled older (≥65years), malnourished (Subjective Global Assessment [SGA] class B/C) adults hospitalized for cardiovascular and pulmonary events congestive heart failure, acute myocardial infarction, pneumonia and/or chronic obstructive pulmonary disease exacerbation in a double-blind, randomized, placebo-controlled trial (NOURISH study). During hospitalization and until 90 days after discharge, participants received standard-of-care plus a high protein and beta-hydroxy-beta-methylbutyrate containing ONS (S-ONS; n=328) or a placebo supplement (n=324), aimed ato improvement in patients’ overall recovery.

Several proteins of the innate immune system are known to be deregulated with insulin resistance. We here aimed to investigate the relationship among circulating lysozyme (both plasma concentration and activity) and obesity-associated metabolic disturbances.

Plasma lysozyme concentration was determined cross-sectionally in a discovery (Cohort 1, n=137) and in a replication cohort (Cohort 2, n=181), in which plasma lysozyme activity was also analyzed. Plasma lysozyme was also evaluated longitudinally in participants from the replication cohort (n=93). Leukocyte lysozyme expression (LYZ mRNA) were also investigated in an independent cohort (Cohort 3, n=76), and adipose tissue (AT) LYZ mRNA (n=25) and plasma peptidoglycan levels (n=61) in subcohorts from discovery cohort.

Translocation of peptidoglycan (as inferred from its increased circulating levels) was linked to plasma lysozyme, hyperinsulinemia and dyslipidemia in obese subjects. In both discovery and replication cohorts, plasma lysozyme levels and audinal findings suggest that plasma lysozyme might be protective on the development of obesity-associated metabolic disturbances.

Observational studies have reported that tea consumption is associated with risk of stroke. However, this observed association is inconsistent, and whether this observed association is due to confounding factors or reverse causation remains unclear. Thus, we applied a two-sample mendelian randomization (MR) approach to determine whether genetically predicted tea consumption is causally associated with risk of stroke, ischemic stroke (IS), and IS subtypes.

UK Biobank available data (349,376 samples of European ancestry) was used to identify single nucleotide polymorphisms associated with tea consumption (cups/day). The summary statistics for stroke, IS, and IS subtypes were obtained from the MEGASTROKE consortium with 40,585 stroke cases and 406,111 controls.

We found that genetically predicted an extra daily cup of tea consumption was casually associated with a reduced risk of small vessel stroke (odds ratio (OR), 0.79; 95% confidence interval (CI), 0.69-0.91; P=0.001), but not with cardioembolic stroke (OR, 0.97; 95% CI, 0.86-1.09; P=0.582), large artery stroke (OR, 0.95; 95% CI, 0.82-1.10; P=0.506), stroke (OR, 1.00; 95% CI, 0.95-1.06; P=0.889) or IS (OR, 0.95; 95% CI, 0.89-1.01; P=0.083).

Our study provided evidence that genetically predicted an extra daily cup of tea consumption is causally associated with a reduced risk of small vessel stroke.

In this review, we summarize all published cases of a vulva malignancy in pediatric patients (≤21 years) reported in the English language literature for the 50-year period between 1970 and 2020. We estimate that less than 100 malignancies have been reported in total, approximately 50% of which were rhabdomyosarcomas. Invasive squamous cell carcinomas, yolk sac tumors, Ewing sarcoma/primitive neuroectodermal tumors (ES/PNET) and melanomas each represented approximately 10% of reported cases. For rhabdomyosarcoma, the alveolar and embryonal subtypes were reported with equal frequency, with both representing 70% of cases combined. The average patient age was 9.8 years. 48% and 35% were Intergroup Rhabdomyosarcoma Study clinical groupings I and III respectively. Managements were generally multimodal, and overall outcomes for the group were favorable. For ase at follow-up. Pediatric vulvar malignancies are rare and are mostly comprised of 5 entities. Their accurate pathologic classification is necessary to facilitate optimal management.There exists a subgroup of patients who undergo neck dissection (ND) who postoperatively complain of either neuropathic pain, dysaesthesia and/or discomfort that is located within the dermatomal distribution of the cervical plexus. The purpose of our study was to determine the prevalence, characteristic, and demographics of these symptoms in our patient cohort. We undertook a retrospective randomised observational cohort study of 105 patients who had undergone ND. The primary predictor variable was the undertaking of a ND. The secondary outcome variable was the complaint of either neuropathic pain or a noxious neuropathy, at a minimum of twelve months after surgery. A recognised symptom questionnaire and a visual analogue score was employed for the purpose of the study. A descriptive and statistical analysis was applied to the assembled data. Twenty patients (19%) complained of either spontaneous (n=9) or evoked (n=11) neuropathic pain that occurred within the surgical site. In addition, 71 patients (68%) described an altered sensation in the dermatomal distribution of the great auricular or tranverse cervical nerves while 70 patients (67%) described the feeling of 'neck tightness’. There were no characteristics of the study cohort that underpinned these results. Neuropathic pain can occur following ND. This can cause distress to a small but defined group of patients. Despite its importance, we found a paucity of studies in the literature that have investigated neuropathic pain following ND. We believe this condition requires more research attention and clinical awareness.Designing safe, effective, efficient, equitable, and person-centred services normally takes some time and a great deal of stakeholder engagement and shared understanding to gain traction. This year has seen a significant acceleration of these activities plus new organisational and clinical collaborations and rapid cycle learning systems as a result of the challenges associated with the COVID-19 pandemic response. Whether it is a WhatsApp group where clinician’s share their real-time understanding of a new disease or a collaboration of manufacturing organisations and clinicians to develop new/more equipment, change and innovation are working at an accelerating pace. We have built upon the NHS leadership guide we used in the College’s leadership development programme and 2019 webinars, Developing People, Improving Care. We explain how using the guide and new evidence in support of the approach along with the learning from 2020 could ensure that excellent innovations and ways of working remain while others are adapted as the crisis evolves to a new normal. Our intention is to provide a road map and personal and team strategies that will deliver ongoing and strong clinical leadership as well as improved quality of care.In COVID-19, acute respiratory distress syndrome (ARDS) and thrombotic events are frequent, life-threatening complications. Autopsies commonly show arterial thrombosis and severe endothelial damage. Endothelial damage, which can play an early and central pathogenic role in ARDS and thrombosis, activates the lectin pathway of complement. Mannan-binding lectin-associated serine protease-2 (MASP-2), the lectin pathway’s effector enzyme, binds the nucleocapsid protein of severe acute respiratory syndrome-associated coronavirus-2 (SARS-CoV-2), resulting in complement activation and lung injury. Narsoplimab, a fully human immunoglobulin gamma 4 (IgG4) monoclonal antibody against MASP-2, inhibits lectin pathway activation and has anticoagulant effects. In this study, the first time a lectin-pathway inhibitor was used to treat COVID-19, six COVID-19 patients with ARDS requiring continuous positive airway pressure (CPAP) or intubation received narsoplimab under compassionate use. At baseline and during treatment, circulating endothelial cell (CEC) counts and serum levels of interleukin-6 (IL-6), interleukin-8 (IL-8), C-reactive protein (CRP) and lactate dehydrogenase (LDH) were assessed. Narsoplimab treatment was associated with rapid and sustained reduction of CEC and concurrent reduction of serum IL-6, IL-8, CRP and LDH. Narsoplimab was well tolerated; no adverse drug reactions were reported. Two control groups were used for retrospective comparison, both showing significantly higher mortality than the narsoplimab-treated group. All narsoplimab-treated patients recovered and survived. Narsoplimab may be an effective treatment for COVID-19 by reducing COVID-19-related endothelial cell damage and the resultant inflammation and thrombotic risk.

To investigate the metal ion release, surface roughness and cytoxicity for Co-Cr alloys produced by different manufacturing techniques before and after heat treatment. In addition, to evaluate if the combination of materials affects the ion release.

Five Co-Cr alloys were included, based on four manufacturing techniques. Commercially pure titanium, CpTi grade 4 and a titanium alloy were included for comparison. The ion release tests involved both Inductive Coupled Plasma Optical Emission Spectrometry and Inductive Coupled Plasma Mass Spectrometry analyses. The surface analysis was conducted with optical interferometry. Cells were indirectly exposed to the materials and cell viability was evaluated with the MTT (3-(4.5-dimethylthiazol-2-yl)-2.5-diphenyltetrazolium bromide) method.

All alloys showed a decrease of the total ion release when CpTi grade 4 was present. The total ion release decreased over time for all specimens and the highest ion release was observed from the cast and milled Co-Cr alloy in acidic conditions. The cast and laser-melted Co-Cr alloy and the titanium alloy became rougher after heat treatment. All materials were within the limits of cell viability according to standards.

The ion release from Co-Cr alloys is influenced by the combination of materials, pH and time. Surface roughness is influenced by heat treatment. Furthermore, both ion release and surface roughness are influenced by the manufacturing technique and the alloy type. The clinical implication needs to be further investigated.

To determine whether dentin-adhesive interface stability would be improved by dimethyl sulfoxide (DMSO) wet-bonding and epigallocatechin-3-gallate (EGCG).

Etched dentin surfaces from sound third molars were randomly assigned to five groups according to different pretreatments group 1, water wet-bonding (WWB); group 2, 50% (v/v) DMSO wet-bonding (DWB); groups 3-5, 0.01, 0.1, and 1 wt% EGCG-incorporated 50% (v/v) DMSO wet-bonding (0.01%, 0.1%, and 1%EGCG/DWB). Singlebond universal adhesive was applied to the pretreated dentin surfaces, and composite buildups were constructed. Microtensile bond strength (μTBS) and interfacial nanoleakage were respectively examined after 24 h water storage or 1-month collagenase ageing. In situ zymography andStreptococcus mutans (S. mutans) biofilm formation were also investigated.

After collagenase ageing, μTBS of groups 4 (0.1%EGCG/DWB) and 5 (1%EGCG/DWB) did not decrease (p > 0.05) and was higher than that of the other three groups (p < 0.05). Nanoleakage expression of groups 4 and 5 was less than that of the other three groups (p < 0.05), regardless of collagenase ageing. Metalloproteinase activities within the hybrid layer in groups 4 and 5 were suppressed. Furthermore, pretreatment with 1%EGCG/DWB (group 5) efficiently inhibited S. mutans biofilm formation along the dentin-adhesive interface.

This study suggested that the synergistic action of DMSO wet-bonding and EGCG can effectively improve dentin-adhesive interface stability. This strategy provides clinicians with promising benefits to achieve desirable dentin bonding performance and to prevent secondary caries, thereby extending the longevity of adhesive restorations.

To evaluate the effect of aging on the microstructural, mechanical, and optical properties of an experimental zirconia-toughened alumina composite with 80%Al

O

and 20%ZrO

(ZTA Zpex) compared to a translucent zirconia (Zpex) and Alumina.

Disc-shaped specimens were obtained by uniaxial and isostatic pressing the synthesized powders (n = 70/material). After sintering and polishing, half of the specimens underwent aging (20 h, 134 °C, 2.2 bar). Crystalline content and microstructure were evaluated using X-ray diffraction and scanning electron microscopy, respectively. Specimens underwent biaxial flexural strength testing to determine the characteristic stress, Weibull modulus, and reliability. Translucency parameter (TP) and Contrast ratio (CR) were calculated to characterize optical properties.

ZTA Zpex demonstrated a compact surface with a uniform dispersion of zirconia particles within the alumina matrix, and typical alumina and zirconia crystalline content. ZTA Zpex and alumina exhibited higher CR material for long span fixed dental prostheses specially where darkened substrates, such as titanium implant abutments or endodontically treated teeth, demand masking.The unprecedented scale of testing required to effectively control the coronavirus disease (COVID-19) pandemic has necessitated urgent implementation of rapid testing in clinical microbiology laboratories. To date, there are limited data available on the analytical performance of emerging commercially available assays for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and integration of these assays into laboratory workflows. Here, we performed a prospective validation study of a commercially available assay, the AusDiagnostics Coronavirus Typing (8-well) assay. Respiratory tract samples for SARS-CoV-2 testing were collected between 1 March and 25 March 2020. All positive samples and a random subset of negative samples were sent to a reference laboratory for confirmation. In total, 2673 samples were analysed using the Coronavirus Typing assay. The predominant sample type was a combined nasopharyngeal/throat swab (2640/2673; 98.8%). Fifty-four patients were positive for SARS-CoV-2 (2.0%) using the Coronavirus Typing assay; 53/54 (98.1%) positive results and 621/621 (100%) negative results were concordant with the reference laboratory. Compared to the reference laboratory gold standard, sensitivity of the Coronavirus Typing assay for SARS-CoV-2 was 100% (95% CI 93.2-100%), specificity 99.8% (95% CI 99.1-100%), positive predictive value 98.1% (95% CI 90.2-99.7%) and negative predictive value 100% (95% CI 99.4-100%). In many countries, standard regulatory requirements for the introduction of new assays have been replaced by emergency authorisations and it is critical that laboratories share their post-market validation experiences, as the consequences of widespread introduction of a suboptimal assay for SARS-CoV-2 are profound. Here, we share our in-field experience, and encourage other laboratories to follow suit.

To demonstrate an innovative idea for a four-petal method for performing laparoscopic adenomyomectomy on a patient with focal-type adenomyosis.

A step-by-step explanation of the technique with narrated video footage.

University hospital.

A 38-year-old female with a 7 × 4 cm adenomyoma at the anterior uterine wall.

Laparoscopic adenomyomectomy began with a cruciate incision to turn the adenomyoma into the shape of a blooming four-petal flower to fully expose the tumor and maximize the removal of adenomyotic tissue. During excision of the lesion, around a 1 cm thickness of the myometrium was preserved at the subendometrial region and around a 0.5 cm thickness of the serosa flap was also left in each „petal.” Suture repair in the method introduced is different from closing the wound by approximation of myometrium to myometrium as in traditional myomectomy; instead, herein we repaired the adenomyomectomy wound by anchoring the serosal flap to the subendometrial tissue, with care taken to avoid dead spacly facilitates a balance between the maximized resection of the lesions and tailored reserves of myometrium. Subsequent repair by anchoring the serosal flap to the subendometrial tissue ensures adequate thickness of the uterine wall after the operation.

To estimate the prevalence of ovulatory cycles in eumenorrheic subfertile women and compare the diagnostic accuracy of a single ultrasound with serum midluteal progesterone measurement in detecting ovulatory cycles.

Prospective diagnostic accuracy study.

University-level hospital.

A total of 208 subfertile eumenorrheic women.

None.

To estimate the prevalence of ovulatory cycles in eumenorrheic women and compare the diagnostic accuracy of a single, well-timed ultrasound scan (index test) with serum progesterone measurement (reference test) by calculating the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and positive likelihood ratio (LR+) and negative likelihood ratio (LR-).

The prevalence of ovulatory cycles among subfertile eumenorrheic women was 92.9% and 99.5% when midluteal serum progesterone level and ultrasound scanning were used as the reference test, respectively. The sensitivity, specificity, PPV, and NPV of ultrasound in identifying ovulatory cycles were 100%, 7.1%, 93.4%, and 100%, respectively. The LR+ and LR- were 1.1 and 0, respectively. The agreement between the ultrasound and serum progesterone was almost perfect (prevalence and bias-adjusted kappa = 0.81.

The prevalence of ovulatory cycles in eumenorrheic subfertile women appears to be high. A single well-timed ultrasound can be performed to identify ovulatory cycles during the infertility workup in eumenorrheic women.

Conceptual ambiguities prevent advancements in end-of-life decision making in clinical practice and research.

To clarify the components of and stakeholders (patients, caregivers, healthcare providers) involved in end-of-life decision making in the context of chronic life-limiting disease and develop a conceptual model.

Walker and Avant’s approach to concept analysis.

End-of-life decision making is a process, not a discrete event, that begins with preparation, including decision maker designation and iterative stakeholder communication throughout the chronic illness (antecedents). These processes inform end-of-life decisions during terminal illness, involving 1) serial choices 2) weighed in terms of potential outcomes 3) through patient and caregiver collaboration (attributes). Components impact patients’ death, caregivers’ bereavement, and healthcare systems’ outcomes (consequences).

Findings provide a foundation for improved inquiry into and measurement of the end-of-life decision making process, accounting for the dose, content, and quality the antecedent and attribute factors that collectively contribute to outcomes.

The variety of concepts and policies relating to yield increases fail to integrate an important constituent of production and human nutrition – biodiversity. We develop an analytical framework to unpack this biodiversity-production mutualism (BPM), which bridges the research fields of ecology and agroeconomics and makes the trade-off between food security and protection of biodiversity explicit. By applying the framework, the incorporation of agroecological principles in global food systems are quantifiable, informed assessments of green total factor productivity (TFP) are supported, and possible lock-ins of the global food system through overintensification and associated biodiversity loss can be avoided.

Ultrasonography has been shown to be a useful tool for diagnosing pneumothorax in the hands of experts. After performing bronchopleural procedures, the recommendation is to perform chest radiography to rule out complications. Our objective was to determine the validity of thoracic ultrasonography to rule out pneumothorax after invasive procedures, conducted by pulmonologists without experience in this procedure.

Our observational prospective study consecutively included patients who underwent transbronchial biopsy (TBB), evacuating thoracentesis (ECT) and/or transparietal pleural biopsies (TPB) who were indicated subsequent chest radiography to rule out complications. In all cases, the same pulmonologist who performed the technique performed an ultrasound immediately after the procedure. A diagnosis of pneumothorax was considered the presence of a lung point or the combination of the following signs absence of pleural sliding, absence of B-lines and presence of the «barcode» sign.

We included 275 procedures (149 TBBs, 36 TPBs, 90 ECTs), which resulted in 14 (5.1%) iatrogenic pneumothoraxes. Ultrasonography presented a sensitivity of 78.5%, a specificity of 85% and a positive and negative predictive value of 22% and 98.6%, respectively. Ultrasonography did not help detect the presence of 3 pneumothoraxes, one of which required chest drainage, but adequately diagnosed 2 pneumothoraxes that were not identified in the initial radiography.

Thoracic ultrasonography performed by pulmonologists at the start of their training helps rule out pneumothorax with a negative predictive value of 98.6%, thereby avoiding unnecessary radiographic control studies in a considerable number of cases.

The Pesticide Toxicity Index (PTI) was used to estimate the potential chronic and acute toxicity to three taxonomic groups – fish, cladocerans, and benthic invertebrates. For invertebrates (either cladocerans, benthic invertebrates, or both), the maximum PTI score exceeded the predicted acute toxicity screening level at 18 of the 72 sites (25%) at some point during WY 2013-2017. The predicted toxicity of a single pesticide compound was found to overwhelm the toxicity of other pesticides in the mixtures after concentrations were toxicity weighted. For this study, about 71%, 72%, and 92% of the Fish-, Cladoceran-, and Benthic Invertebrate-PTI scores, respectively, had one pesticide compound prih, there were three pesticide types that contributed the most to predicted chronic (>0.1) PTIs – acetochlor, an herbicide; carbendazim, a fungicide degradate; and piperonylbutoxide, a synergist.

There exists substantial variability in the management of pelvic ring injuries among pelvic trauma surgeons. The objective of this study was to perform a comprehensive survey on the management of pelvic ring injuries among an international group of pelvic trauma surgeons to determine areas of agreement and disagreement.

A 45-item questionnaire was developed using an online survey platform and distributed to 30 international pelvic trauma surgeons. The survey consisted of general questions on the acute management of pelvic ring injuries and questions regarding 5 cases Lateral compression (LC) type 1 injury, LC-3, Anterior-posterior compression (APC) type 3 injury, a combined vertical shear (VS) injury through the sacrum, and VS injury through sacroiliac joint. Respondents were shown blinded anteroposterior pelvis radiographs and axial computed tomography (CT) images for each case and asked if the injury needed fixation, the type of fixation, the order of fixation, and postoperative weight-bearing status. T these areas with a lack of agreement to decrease practice variability and improve patient outcomes.

This study identified specific areas of pelvic ring injury management with minimal to no agreement among pelvic trauma surgeons. Future research should target these areas with a lack of agreement to decrease practice variability and improve patient outcomes.

This study was designed to determine prevalence and potential correlates of family refusal to organ donation for patients declared brain dead thorough a 12-year retrospective data analysis.

Of 111 cases declared brain dead by our hospital within a 12-year period between 2008 and 2019, a total of 82 potentially brain-dead organ donors were included in this retrospective study. Data on sociodemographic characteristics, length of intensive care unit stay, cause of death, decedent’s wishes, interview time, family decision, and reasons for refusal were recorded.

The rate of family refusal to organ donation was 51.2% and because of religious concerns (64.3%) in most of cases. The likelihood of family consent to organ donation was significantly higher for an adult vs a child (60.0% vs 25.9%, P= .004) and for a schooler and adolescent age vs a younger child (55.6 vs 22.5%, P= .004). Patients who were declared brain dead after nontraumatic intracranial hemorrhage (60.4%) vs encephalitis (18.2%) had higher rates ted across different family refusal reasons in terms of sociodemographic factors, length of intensive care unit stay, awareness of decedent’s wishes, or time of family interview.Microalgae have potential for environmental remediation, but they must better tolerate stress. Adaptive laboratory evolution (ALE) is effective to construct evolved strains, but its efficiency is low. Highly efficient ALE relies on selecting suitable environmental stress, original strain selection, and optimizing initial cell density and stress strategy.

The coronavirus pandemic has changed health care rapidly and dramatically.

To provide a critical synthesis of the scientific literature on the pandemic’s implications for psychiatric practice.

A rapid literature review was undertaken to identify scientific literature linking psychiatric outcomes and practice changes due to coronavirus and the disease it causes (COVID-19). A structured quality assessment was used to assess those articles reporting quantitative data.

Fifty articles were identified for inclusion, but only 12 contained original data. Eleven of those twelve were rated as of weak quality. The literature described psychiatric sequelae of the coronavirus and related public health interventions through cross-sectional surveys among different populations; no studies include diagnostic or functional impairment data. Populations at risk include COVID-19 survivors, health care workers, the elderly, and those with preexisting psychiatric disease. Impacts on psychiatric practice were described, again without data on changes to quality or access of care.
