Leptin is an adipose tissue hormone that acts as energy sensor and reproductive function regulator. Recent reports suggest that leptin is involved in mitochondrial biogenesis in different tissue cells. Herein, we hypothesized that leptin could also affect Sertoli cells mitochondrial dynamics and biogenesis. Human Sertoli cells (hSCs) were cultured in the presence of different leptin concentrations (5, 25 and 50 ng/mL) or vehicle for 24 h. The three different leptin concentrations were selected to mimic the circulating levels found either in normal weight, obese, and morbidly obese individuals, respectively. Leptin receptor (LEPR) expression was evaluated as well as mitochondrial membrane potential, complexes levels, complex II activity and basal respiration. Moreover, mitochondrial DNA copy number and expression of mitochondrial biogenesis markers were assessed. In hSCs, leptin concentrations similar to those found both in lean men decreased mitochondrial complex II protein levels, but no changes in its activity were observed. This is in agreement with basal respiration and mitochondrial membrane potential assessments, which indicate no alterations in mitochondrial fitness. Furthermore, no changes in mitochondrial biogenesis markers were observed upon leptin exposure, although SIRT1/3 levels were increased after exposure to the highest leptin concentration. Overall, the increase in SIRT1/3 levels suggests a role for leptin in glycolysis, which given the relevance of SCs glycolytic flux for germ cells nutritional support further reinforces that this mechanism can be linked to obesity-related subfertility/infertility.Diabetic macular edema (DME), characterized by exudative fluid accumulation in the macula, is the most common form of sight-threatening retinopathy in patients with diabetes. The management of DME has changed considerably in recent years, especially following the development of intravitreal anti-vascular endothelial growth factor therapy which has emerged as a first-line therapy for center-involved DME. Laser treatment, intravitreal steroid therapy, and vitrectomy are also important treatment options for DME. We believe that it is important to choose the most appropriate treatment option for DME based on the clinical evidences, in addition to the careful consideration of individual patients' general or ocular condition, DME characteristics, patients' motivation, and compliance to the treatment in real-world clinical practice. In this review, we have summarized important clinical evidences for the main treatments for DME, presented an expert review for these evidences, and proposed a recommended therapeutic flow chart for DME. We hope that our review of the clinical evidences and the recommended therapeutic flow chart for DME will contribute to better treatment outcome for DME.
This study aimed to identify acute angle closure (AAC) risk following pharmacologic mydriasis and the factors affecting post-mydriatic intraocular pressure (IOP) in a population with a high prevalence of angle closure disease.

In total, 460 individuals aged ≥ 72 years were enrolled in this cross-sectional community-based screening program. IOP was measured at baseline and 1 hour after mydriasis. Individuals with post-mydriatic IOP spike > 6 mmHg received indentation gonioscopy and IOP-lowering medication. Linear regression analysis was used to identify ocular parameters associated with post-mydriatic IOP elevation.

The mean age of participants was 77.8 ± 4.1 years, and 65.4% of them were men. In total, 21 eyes of 16 participants (3.48%) had post-mydriatic IOP spikes (range 6-13.7 mmHg); among them, 15 eyes had an IOP of > 21 mmHg. None of the participants developed AAC. All eyes with IOP spikes were phakic, except for one with pseudophakic angle closure. Analysis of 381 participants with at least one phakic eye revealed that higher post-mydriatic IOP and IOP changes were associated with narrower angle grading, more extensive peripheral anterior synechiae, shallower central anterior chamber, and thicker lens. According to multiple linear regression analysis, post-mydriatic IOP was independently associated with baseline IOP and factors suggestive of crowded anterior chamber based on gonioscopic findings and central or peripheral anterior chamber depth evaluation in conjunction with lens thickness.

Post-mydriatic IOP should be measured in phakic eyes with a crowded anterior chamber. Post-mydriatic IOP spikes can be effectively blunted with intervention to prevent AAC.

To quantify the association between visit adherence and visual acuity (VA) in diabetic macular edema (DME).

This secondary analysis of the 2-year DRCRnet Protocol T study of 656 patients required one visit every 4 weeks in the first year, then at variable 4-16-week intervals in the second year. Visit adherence measured as number of missed visits, average (avg days) and longest (max days) visit interval, average (avg missed days) and longest (max missed days) unintended visit interval, and visit constancy (percentage of 3-month periods with at least 1 visit). read more Avg and max missed days were categorized as on time (0 days), late (> 0-60 days), and very late (> 60 days). Primary outcome was change in ETDRS VA between baseline study visit and last attended visit, using multivariate linear regression models controlling for age, gender, race, ethnicity, treatment arm, baseline VA, hemoglobin A1c, insulin use, and number of lasers and injections.

Mean number of missed visits was 1.7. 616 (94%) patients had 100% visit constancy. A total of 331 (51%) patients were on time, 171 (26%) late, and 154 (23%) very late in avg missed days. Max missed days ranged 0-696 days. Adjusted, each missed visit was associated with 0.3-letter decrease (95%CI - 0.6, - 0.1, p = 0.02); being very late in avg and max missed days saw - 4.2 letters (95%CI - 6.4, - 2.0, p < 0.001) and - 4.0 letters (95%CI - 6.1, - 1.9, p < 0.001), respectively, than on time. Those that averaged > 4 days missed per attended visit saw 4.6 letters worse (95%CI - 7.3, - 2.0, p < 0.001).

In such plant systems, when pre-pollination barriers are weak, relatively strong post-pollination reproductive barriers are required to maintain species boundaries. Even when post-pollination barriers are in place, however, reproductive interference and pollinator dependence may strengthen selection for pre-pollination barriers. We assessed whether coexistence of species from the unusually speciose Erica genus in the fynbos biome, South Africa, is enabled through pre-pollination or post-pollination barriers. We also tested for reproductive interference and pollinator dependence. We investigated this in natural populations of three bird-pollinated Erica species (Erica plukenetii, E. curviflora and E. coccinea), which form part of a large guild of congeneric species that co-flower and share a single pollinator species (Orange-breasted Sunbird Anthobaphes violacea). At least two of the three pre-pollination barriers assessed (distribution ranges, flowering phenology and flower morphology) were weak in each species pair. Hand-pollination experiments revealed that seed set from heterospecific pollination (average 8%) was significantly lower than seed set from outcross pollination (average 50%), supporting the hypothesis that species boundaries are maintained through post-pollination barriers. Reproductive interference, assessed in one population by applying outcross pollen three hours after applying heterospecific pollen, significantly reduced seed set compared to outcross pollen alone. This may drive selection for traits that enhance pre-pollination barriers, particularly given that two of the three species were self-sterile, and therefore pollinator dependent. This study suggests that post-pollination reproductive barriers could facilitate the coexistence of congeneric species, in a recent radiation with weak pre-pollination reproductive barriers.
This manuscript is a narrative review of peer-reviewed studies of postdural puncture headache (PDPH) as the most common complication of a diagnostic and therapeutic lumbar puncture (LP) and LP due to the damage of the dura mater in epidural anesthesia.

Author searched articles related to the PDPH and its risk factors, pathophysiology diagnosis, differential diagnosis, and therapy. All studies according to the analyzed parameters and their relevance to the clinical practice, as well as quality of the study methods, were selected for further analysis.

The review presents the clinical and paraclinical prediction criteria for the onset, clinical features, course, and efficiency of specific therapeutic interventions which are of a particular clinical benefit for the prevention, pathogenetic treatment, and differential diagnosis of PDPH. The analysis of prediction parameters for the onset, clinical course, and associated symptoms and signs of PDPH is a contribution to the understanding of pathophysiology of intracranial hypotension, since PDPH can be considered a clinical model of intracranial hypotension.

Given that LP is a common procedure in clinical practice, it is necessary to have a comprehensive knowledge of the risk factors, pathophysiological, diagnostic, differentially diagnostic, and therapeutic aspects of PDPH.

Fingolimod, an oral sphingosine 1-phosphate receptor modulator, is approved by EMA for relapsing-remitting multiple sclerosis (RRMS).

To assess the effectiveness and safety of fingolimod in patients with RRMS in real-world clinical practice in Portugal.

Retrospective, multicentre, non-interventional study, reporting 3 years follow-up of data collected from October 2015 to July 2016. Sociodemographic data and previous treatments at baseline and data regarding disease evolution, including number of relapses, annualised relapse rates (ARR) and Expanded Disability Status Scale (EDSS), were collected.

Two-hundred and seventy-five participants were enrolled in the REALMS study. Results showed that the main reason to switch to fingolimod was failure of previous treatment (56.7%) and only 3.6% were naïve patients. In the total population, there was a significant decrease in ARR of 64.6% in the first year of treatment, 79.7% in the second year and 82.3% in the third year, compared with baseline. More than 67.0% of patients had no relapses during the 3 years after switching to fingolimod. EDSS remained stable throughout the study.

Therapy with fingolimod showed a sustained effectiveness and safety over the 3 years, particularly on patients switched from first-line drugs (BRACE). No new safety issues were reported.
