Metformin also reduced circulating IGF-2 (P < 0.05) and IGFBP-3 (P < 0.01) but increased IGF bioactivity (P < 0.05). At baseline, IGF-2 correlated significantly with the hepatic insulin resistance (r2= 0.28, P < 0.05). PAPP-A remained unchanged but STC2 declined significantly (P < 0.05) following metformin administration. During metformin treatment, change in HOMA IR correlated with the change in STC2 (r2= 0.35, P < 0.05).

Metformin administration alters many components of the circulating IGF system, either directly or indirectly via improved insulin sensitivity. Reduction in IGF-2 and STC2 may provide a novel mechanism for a potential metformin-induced antineoplastic effect.

We performed a randomized phase II study evaluating everolimus with or without bevacizumab in patients with advanced pNETs. One hundred and fifty patients were randomized to receive everolimus 10 mg daily with or without bevacizumab 10 mg/kg i.v. every 2 weeks. Patients also received standard dose of octreotide in both arms. The primary endpoint was PFS, based on local investigator review. Treatment with the combination of everolimus and bevacizumab resulted in improved progression-free survival compared to everolimus (16.7 months compared to 14.0 months; one-sided stratified log-rank P = 0.1028; hazard ratio (HR) 0.80 (95% CI 0.56-1.13)), meeting the predefined primary endpoint. Confirmed tumor responses were observed in 31% (95% CI 20%, 41%) of patients receiving combination therapy, as compared to only 12% (95% CI 5%, 19%) of patients receiving treatment with everolimus (P = 0.0053). Median overall survival duration was similar in the everolimus and combination arm (42.5 and 42.1 months, respectively). Treatment-related toxicities were more common in the combination arm. In summary, treatment with everolimus and bevacizumab led to superior PFS and higher response rates compared to everolimus in patients with advanced pNETs. Although the higher rate of treatment-related adverse events may limit the use of this combination, our results support the continued evaluation of VEGF pathway inhibitors in pNETs.

Thyroid disease during pregnancy is associated with adverse pregnancy outcomes and suboptimal fetal development. During the last decades, guidelines for diagnosing thyroid disease during pregnancy have changed considerably and there has been increased awareness. This study aimed to describe the prevalence of thyroid disease treatment over time among pregnant women in Norway.

Nationwide register-based study.

We combined historical data from the Medical Birth Registry of Norway and the Norwegian Prescription Database, identifying pregnant women using thyroid therapy from 2004 to 2018.

A total of 855,067 pregnancies were included in the analyses. The proportion of women using thyroid hormone replacement therapy during pregnancy increased from 1.46% (n = 800) in 2004 to 3.57% (n = 1940) in 2018. The proportion of women using antithyroid medications also increased from 0.04% (n = 20) in 2004 to 0.10% (n = 56). During these 15 years, the mean maternal age increased by 0.9 years. When adjusting for age, the risk for being on thyroid hormone replacement therapy during pregnancy increased by an average of 5% per year (odds ratio 1.05, 95% CI 1.05-1.05).

During the recent 15 years, there has been a substantial increase in the use of thyroid hormone therapy in Norwegian pregnant women. We speculate that this could be due to an increased awareness in combination with overdiagnosis because of inappropriate diagnostic criteria. To truly understand the possible causes and consequences of this development, further research is warranted.

Adhesions after tendinopathy in individuals who perform physical work and those physically active in middle age are a challenging problem for orthopedic surgeons. We evaluated the effects of human-derivated amniotic membrane on tendon healing, adhesions, angiogenesis, and the inflammatory process.

Thirty-five rats were divided evenly into five groups, and the left lower extremity was used in this study. No interventions were applied to the control group (group 5). In the other groups, Achilles tendons were partially cut to the midline. Then, primary repair (group 1), amniotic membrane treatment with no repair (group 2), primary repair and amniotic membrane treatment (group 3), or secondary healing with no repair (group 4) was performed.

Use of amniotic membrane in tendon healing resulted in decreased adhesion formation and positive effects on collagen sequencing and anti-inflammatory effects. In addition, for the vascular endothelial growth factor evaluation there was no difference among the amniotic membrane repair groups, but there was an increase in vascular endothelial growth factor positivity compared with the control group.

These data show that amniotic membrane treatment can alter biological behavior and induce surface-dependent angiogenesis and can have angiogenetic effects on ischemia and inflammation.

The aim of this study is to compare clinical and radiologic outcomes of self-adhesive taping (SAT) or a short- leg cast (SLC) groups with base of fifth metatarsi.

Functional outcome was assessed by the Visual-Analogue-Scale Foot and Ankle (VAS-FA) at the Emergency and at 2, 4, 6, and 12 weeks. Labour loss, bone union and The American Orthopedic Foot and Ankle Score (AOFAS) at 12 weeks were also assessed.

There was no difference between the SAT group and SLC group in VAS-FA scores at time of injury, 6 and 12 weeks. The SAT group had a significantly higher mean VAS-FA score at the second and fourth weeks of follow-up compared with the SLC group (P = .001 and P = .039, respectively). No correlation was observed between the fracture gap and functional scores for both groups. There was no difference in AOFAS between two groups at 12 weeks. Twenty one patients were unable to work for a mean of 38.2 days during the treatment. 10 patients with the SAT missed 37.5 days and eleven patients with the SLC g missed 40.2 (p 0.41). The bone union was also achieved for all patients within 12 weeks.

Treatment with SAT in these fractures had satisfactory functional results compared with traditional SLC. Although there were no significant differences in labor loss and use of assistive devices, The VAS-FA score was significantly higher in SAT group than the SLC group at the second and fourth weeks of treatment.

Many conservative treatments have been advanced for plantar fibromas, including accommodative orthotic devices, which help but do not cure the disease. Surgery is considered the mainstay of treatment for this malady, but the failure rate has been as high as 100%, depending on the type of fasciectomy. Radiotherapy is a new, exciting modality that has shown promising results for treating plantar fibromas.

The practice of flamenco dance involves great biomechanical demands, comparable with a high-performance sport. The technical movements of the footwork tap, the jumps, and the turns increase the prevalence of injuries and pathologic disorders of the foot and lower limb. Limited research has examined adaptation of the foot posture and dorsiflexion of the ankle in flamenco dancing. Therefore, the aim of this study was to evaluate whether the practice of flamenco dancing produces modifications in the ankle’s dorsiflexion range of motion, Foot Posture Index, or pronation.

A cross-sectional observational study with intentional sampling was performed with 26 individuals (52 feet) in two groups professional female flamenco dancers (n = 13) and nondancers (n = 13). The participants were assessed in a single session for ankle dorsiflexion, foot pronation (navicular drop test), and foot posture (Foot Posture Index).

Significant differences were found between the two groups for left foot Foot Posture Index (P = .007) and right foot navicular drop test (P = .006).

The results of this study indicate that flamenco dancing can produce modifications in the Foot Posture Index and foot pronation versus nondancers. Further research is required.

Diabetic lower-extremity disease is the primary driver of mortality in patients with diabetes. Amputations at the forefoot or ankle preserve limb length, increase function, and, ultimately, reduce deconditioning and mortality compared with higher-level amputations, such as below-the-knee amputations (BKAs). We sought to identify risk factors associated with amputation level to understand barriers to length-preserving amputations (LPAs).

Diabetic lower-extremity admissions were extracted from the 2012-2014 National Inpatient Survey using ICD-9-CM diagnosis codes. The main outcome was a two-level variable consisting of LPAs (transmetatarsal, Syme, and Chopart) versus BKAs. Logistic regression analysis was used to determine contributions of patient- and hospital-level factors to likelihood of undergoing LPA versus BKA.

The study cohort represented 110,355 admissions nationally 42,375 LPAs and 67,980 BKAs. The population was predominantly white (56.85%), older than 50 years (82.55%), and male (70.38%). On meceive higher-level amputations. Further examination is required to determine whether earlier referral to multidisciplinary centers is more effective at reducing BKA rates versus satellite centers in rural localities.Exploration of the dual and opposing facets of estrogen necessitates a clear understanding to diminish the controversy of estrogen regulation in averting the systemic, autoimmune, joint degrading disorder, and rheumatoid arthritis (RA). Experimental evidences consider estrogen as a pivotal enzyme to modulate the disease progression via managing several cellular mechanisms targeting inflammatory markers such as TNF, ILs, nuclear factor kappa B, and other regulatory proteins like matrix metalloproteinases impeding joint erosion and cartilage degradation. Estrogen modulates cellular signaling associated with inflammation, oxidative stress, related cardiovascular risk, and miRNA regulation during RA progression. Studies determining estrogen regulation in RA complicate the resemblance of the outcome as they represent both hyper and hypo level of estrogen is linked to the disease. Although some reports deliver estrogen as malign, there is now increasing evidence of rendering protection dose dependently. Variation in estrogen level causes differential expression of certain proteins and their related signaling which is directly or indirectly linked to RA pathogenesis.
