Mitochondrial dysfunction is a major cause and/or contributor to the development and progression of vision defects in many ophthalmologic and mitochondrial diseases. Despite their mechanistic commonality, these diseases exhibit an impressive variety in sex- and tissue-specific penetrance, incidence, and severity. Currently, there is no functional explanation for these differences. We measured the function, relative capacities, and patterns of control of various oxidative phosphorylation pathways in the retina, the eyecup, the extraocular muscles, the optic nerve, and the sciatic nerve of adult male and female rats. We show that the control of mitochondrial respiratory pathways in the visual system is sex- and tissue-specific and that this may be an important factor in determining susceptibility to mitochondrial dysfunction between these groups. The optic nerve showed a low relative capacity of the NADH pathway, depending on complex I, compared to other tissues relying mainly on mitochondria for energy production. Furthermore, NADH pathway capacity is higher in females compared to males, and this sexual dimorphism occurs only in the optic nerve. Our results propose an explanation for Leber's hereditary optic neuropathy, a mitochondrial disease more prevalent in males where the principal tissue affected is the optic nerve. To our knowledge, this is the first study to identify and provide functional explanations for differences in the occurrence and severity of visual defects between tissues and between sexes. Our results highlight the importance of considering sex- and tissue-specific mitochondrial function in elucidating pathophysiological mechanisms of visual defects.
The mainstay empiric treatments of bacterial endophthalmitis are intravitreal vancomycin and ceftazidime. In the United States, up to 10% of the general population has a reported penicillin (PCN) allergy. Despite low cross-reactivity between PCN and later-generation cephalosporins, some providers alter the intravitreal antibiotic choice for endophthalmitis because of concern for allergic reactions. We evaluated the management strategies of infectious endophthalmitis in the setting of self-reported systemic antibiotic allergies and the association with adverse reactions after standard intravitreal antibiotic administration.

Single-center, retrospective cohort study.

All patients with endophthalmitis between 2005 and 2019 and documented PCN, PCN-analog, cephalosporin, or vancomycin allergy who received intravitreal antibiotics on the basis of International Classification of Diseases 9th and 10th Revisions, and Current Procedural Terminology codes.

To report the clinical and imaging characteristics of multiple evanescent white dot syndrome (MEWDS) from a large single-center cohort.

Single-center, retrospective cohort study.

A total of 111 patients previously diagnosed with MEWDS in the Kaiser Permanente Northern California system from 2012 to2019.

Two retina specialists reviewed the medical records and all available retinal imaging, including Humphrey visual field testing, fundus photography (FP), OCT, fluorescein angiogram (FA), and fundus autofluorescence (FAF). Patients were excluded from analysis if confirmatory imaging was unavailable.

Patient characteristics, visual acuity, clinical examination and imaging findings, and final diagnosis.

Seventy-three patients (65.8%) were confirmed to have the diagnosis of MEWDS. Fifty-eight (79.5%) were female, with a mean (standard deviation [SD]) age at presentation of 35.2 (14.2) years, and mean refractive error of-1.6 diopters. Initial mean (SD) visual acuity was logarithm of the minimum angle of m and imaging findings permit recognition of this disease, misdiagnosis is not uncommon.
Multiple evanescent white dot syndrome is a rare self-limiting condition of the outer retina. Selleckchem BIRB 796 Although a distinct set of clinical exam and imaging findings permit recognition of this disease, misdiagnosis is not uncommon.
Evidence is inconsistent for the effect of non-invasive ventilation (NIV) for individuals with chronic obstructive pulmonary disease (COPD) during exercise training. This review aimed to determine the effect of NIV in COPD individuals during exercise training on exercise capacity, quality of life, functional performance and symptoms.

We searched for studies evaluating the effect of NIV on COPD individuals during exercise training published until May 2020 in 6 electronic databases (PubMed, Embase, Cochrane Library, Web of Science, clinical trial registers and Wanfang). The included studies were appraised with the Cochrane Risk of Bias tool and Downs and Black criteria. The primary outcomes were improvement in 6-min walking distance and quality of life. Mean difference (MD) or standardized mean difference (SMD) with 95% confidence intervals (CIs) was calculated.

Among 855 identified articles, reports for 15 studies with heterogeneous populations were eligible, with 520 individuals 257 in the NIV group andining in COPD individuals because the intervention could improve exercise performance and quality of life. The current results also demonstrate the importance of further investigations of higher methodological quality to assess the effect on exercise capacity and quality of life.
Healthy trained athletes generally have an "overbuilt" respiratory system in order to face the huge ventilation and gas-exchange demand imposed by strenuous exercise. Athletes frequently complain of respiratory symptoms regardless of whether they have a diagnosed respiratory disease, therefore evoking a kind of respiratory limitation during exercise. Some respiratory pathologies athletes present are closely linked to exercise and include asthma, exercise-induced bronchoconstriction (EIB) or exercise-induced laryngeal obstruction. Management of asthma and EIB are mainly based on pharmacological treatments. However, many athletes still complain of respiratory symptoms despite optimal pharmacological treatments, which highlights the need for non-pharmacological approaches including breathing retraining, inspiratory muscle training and/or laryngeal exercise performed under the guidance of a physiotherapist in this specific population.

With this literature overview, we aimed to report evidence supporting the interest of rehabilitation for athletes with respiratory disorders and discuss whether inspiratory muscle training programs can improve performance in healthy athletes.
