    Color Doppler ultrasonography (CDU) is widely used to diagnose adnexal torsion (AT). However, its validity remains questionable due to its low sensitivity. Our study aimed to evaluate the accuracy of CDU for the preoperative diagnosis of AT.

    The electronic medical records of patients who were taken to the operating room with the diagnosis of suspected AT were reviewed. Patients having surgically/pathologically-proven AT were compared with patients who were found to have a different pathology at the time of surgery. CDU validity was assessed using a 2 × 2 table and compared with a diagnostic model that consists of the Doppler findings, patient’s age, and previous surgical history.

    AT was diagnosed correctly in 74.6% of cases. Absent Doppler flow was seen in only 18.6% of cases. Although its specificity and positive predictive value were high, CDU had very low sensitivity and negative predictive value. The combined diagnostic model exceeded CDU alone in terms of diagnostic accuracy.

    The use of CDU alone is not a reliable modality to exclude AT. Absent Doppler flow is a sign of ovarian necrosis. Clinical correlation between CDU findings and the patient’s symptoms makes the diagnosis of AT more timely and accurate.

    Intrauterine devices (IUDs) are globally one of the most popular methods of contraception. Uterine perforation is one of the most significant complications of IUD use and commonly occurs at the time of IUD insertion rather than presenting as delayed migration. This paper reports a series of 13 cases of displaced IUDs requiring retrieval by laparoscopy or laparotomy. All the IUDs were copper bearing and most perforations occurred immediately after IUD insertion.

    In two patients with sigmoid colon injury and IUD penetration of the appendix, laparoscopic management had failed and laparotomy was necessary owing to severe obliteration of the pelvic cavity. In one patient laparotomy was the preferred surgical approach owing to acute bowel perforation. In the remaining patients, the displaced devices were successfully removed by laparoscopy.

    Uterine perforation and IUD migration to the organs in the abdominopelvic cavity are serious complications of IUD insertion and can be successfully managed by laparoscopy, or by laparotomy in the presence of severe pelvic adhesions or unexpected complications.

    Studies on etiopathogenesis of attention deficit/hyperactivity disorder (ADHD) are increasingly focussing on mitochondrial dysfunction. Children diagnosed with ADHD who had significantly higher mitochondrial DNA (mtDNA) copy numbers than healthy children in our first study were re-examined in 1-year follow-up to investigate effects of severity and treatment of ADHD on mtDNA.

    Twenty-eight patients who participated in previous study were included in this follow-up study. Patients were equally divided into two groups according to whether they had been receiving treatment. Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, and Conners Parent Rating Scale (CPRS) were used. Polymerase chain reaction was performed.

    Means of the first and second mtDNA copy were similar in all patients. mtDNA copy numbers did not change between two measurements in treated and non-treated groups. There was a correlation between CPRS ADHD index and inattention scores andunctions.

    There may be a relationship between decreased ADHD severity with treatment and positive effects of mitochondrial functions. Mitochondrial dysfunction may play a role in pathophysiology of ADHD.KEY POINTSThis was the first study to follow up ADHD patients in order to investigate mitochondrial dysfunction by measuring mtDNA copy numbers 1 year after the initial measurements.mtDNA copy number, one of the best markers of mitochondrial dysfunction, did not change in ADHD patients over a period of 1 year regardless of treatment.Mitochondrial dysfunction may play a role in the pathophysiology of ADHD, where it may be involved with or without treatment.In the treated group, there was an association between decreased ADHD severity and reduced mtDNA copy numbers.There may be a relationship between decreased ADHD severity with treatment and the positive effects of mitochondrial functions.The chemical characterization study of an endemic plant, Haplanthodes neilgherryensisis (Wight) R.B. Majumdar from Western Ghats of India, resulted in to the isolation of a new flavanone glycoside, 5-hydroxy-7-methoxy-8-O-β-D-glucopyranosyl-2S-flavanone (1), along with 3 known flavonoids, 7-O-methyl dihydrowogonin (2), 7-O-methyl wogonin (3), andrographidine C (4). The structure of 1 was elucidated by using 1 D and 2 D NMR and HRMS experimental data, while for the known compounds, 1H NMR and mass spectrometry data were compared with the reported literature. Compound 1 was tested in vitro to check the improvement in uptake of glucose by the L6 rat skeletal muscle tissues and the observed EC50 value was 5.8 µM, while rosiglitazone showed EC50 of 2.7 µM.Antioxidant activity of organoselenium compounds belonging to different classes i.e. functionalized aliphatic, aromatic and cyclic selenoethers, are compared on the basis of their ability to scavenge reactive oxygen species like hydroxyl and peroxyl radicals and to exhibit glutathione peroxidase (GPx) like catalytic activity. The comparative analysis has revealed that the antioxidant activity of the organoselenium compounds show direct correlation with the energy of the highest occupied molecular orbital (HOMO) and neighboring group participation that stabilizes the reaction intermediate. Finally, structural features responsible for improving the rate of reaction of organoselenium compounds with free radical/molecular oxidants have been discussed on the basis of the compounds screened at our institute.Recently, three-dimensional (3D)-cultured adipose mesenchymal stem cells (ASCs) have provided an effective therapy for liver fibrosis. This study aimed to enhance the potential of human ASCs for antifibrosis or hepatocyte regeneration using a 3D culture system and investigate their therapeutic mechanism in experimental liver fibrosis. ASC-3Dc were generated in a 3D culture system and stimulated with four growth factors, namely epidermal growth factor, insulin-like growth factor (IGF)-1, fibroblast growth factor-2, and vascular endothelial growth factor-A. The expression levels of antifibrotic or hepatic regeneration factors were then measured using quantitative real-time polymerase chain reaction and enzyme-linked immunosorbent assay. The therapeutic effects of ASC-3Dc were determined using a liver fibrosis model induced by thioacetamide. Histological analysis was performed to elucidate the therapeutic mechanism. ASC-3Dc exhibited high levels of hepatocyte growth factor (HGF), IGF-1, stromal cell-derived factor (SDF)-1 genes, and protein expression. In addition, injecting ASC-3Dc significantly prevented hepatic fibrosis and improved liver function in vivo. Moreover, high numbers of ki-67-expressing hepatocytes were detected in the ASC-3Dc-injected livers. Albumin-expressing ASC-3Dc engrafted in fibrotic livers augmented HGF expression. Thus, short-term 3D-cultured ASCs may be a novel alternative to the conventional treatment for liver damage in clinical settings.In this work, we discovered a new phenomenon-asymptomatic COVID-19 infection, or covert case, during the pandemic. All the 3 patients had a history of exposure, with no symptoms, and no abnormalities were found in computed tomography scan or lab tests. Except for case 2, the other patients’ severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) nucleic acid tests were negative. But their anti-SARS-COV-2 nucleocapsid antibody showed a dynamic trend, consistent with the process of virus infection and clearance. A growing number of asymptomatic or covert cases need more attention. Lack of surveillance may lead to another outbreak. We hope to demonstrate our cases to attract the attention of governments or health authorities that covert cases should be the focus as well.

    Some 40% of colorectal cancer (CRC) patients present with anemia. Temporal trends of gradually decreasing Hb are suggested as a supplementary diagnostic tool for CRC. We set out to explore this concept in a strictly defined population.

    A laboratory database identified patients ≥40 years that had ≥1 Hb test reported from primary care, Örebro county in 2000-17. Linkage to the Swedish Colorectal Cancer Registry identified patients diagnosed with CRC. Other primary care patients served as controls (110), matched by age and sex. Prediagnostic Hb in cases and controls were compared and temporal trajectories of Hb modelled using a nonlinear three-parameter logistic function.

    1,534 CRC patients and 15,333 controls were identified. The average number of reported Hb tests in primary care per year increased successively, and diagnostic delay from detection of anemia to diagnosis of CRC decreased; in 2015-17 it was median 4 (IQR 2-6) months. No association was found between last Hb and stage of right-/left-sided colon, or rectal cancer.A statistically significantly lower Hb in CRC patients was discernable 609 days (20 months) prior to diagnosis for men and 905 days (30 months) for women, both in the range of normal Hb. The frequency of Hb testing in the general population

    primary care was surprisingly low, and was ≥50% annually only in octogenarians.

    The findings indicate a potential for Hb trends to inform the diagnostic process of CRC but whether it will translate into any clinical advantage is yet uncertain.

    To investigate the expertise in and support of the implemented new method of cancer patient pathways (CPPs) among general practitioners (GPs) and other working physicians in Sweden.

    A survey in the form of 10 knowledge-based multiple-choice questions (MCQs) and two general questions about CPPs.

    Physicians from two different regions in Sweden answered the survey between December 2018 and January 2019.

    GPs in primary care compared to other physicians. 155 participants completed the survey and the response rate was 65%.

    Physicians’ self-estimated knowledge of CPPs in general and opinion of CPPs effect on mortality and morbidity. Their scores on 10 different MCQs. Scores were analysed in subgroups related to the physicians medical specialty and experience.

    A majority of all physicians (63%) felt that they had insufficient knowledge regarding the procedure of CPPs, and the average score from the MCQs was 3.8 out of 10 correct answers. The results showed that GPs performed significantly better than specialists from other disciplines.
