Male infertility has a complex etiopathology, which mostly remains elusive. Although research has claimed that oxidative stress (OS) is the most likely underlying mechanism of idiopathic male infertility, the specific treatment of OS-mediated male infertility requires further investigation. Coenzyme Q10 (CoQ10), a vitamin-like substance, has been found in measurable levels in human semen. It exhibits essential metabolic and antioxidant functions, as well as playing a vital role in mitochondrial bioenergetics. Thus, CoQ10 may be a key player in the maintenance of biological redox balance. CoQ10 concentrations in seminal plasma directly correlate with semen parameters, especially sperm count and sperm motility. Seminal CoQ10 concentrations have been shown to be altered in various male infertility states, such as varicocele, asthenozoospermia, and medical or surgical regimens used to treat male infertility. Fadraciclib These observations imply that CoQ10 plays an important physiological role in the maintenance and amelioration of semen quality. The present article thereby aimed to review the possible mechanisms through which CoQ10 plays a role in the regulation of male reproductive function, and to concisely discuss its efficacy as an ameliorative agent in restoring semen parameters in male infertility, as well as its impact on OS markers, sperm DNA fragmentation, pregnancy, and assisted reproductive technology outcomes.
Long-COVID is emerging as a significant problem among individuals who recovered from COVID-19. Scant information is available on the prevalence, characteristics, and risk factors for long-COVID among people living with HIV (PLHIV).

A tertiary level, private, HIV clinic in western India.

A prospective, observational study was conducted to assess the prevalence of long-COVID among PLHIV. Long-COVID was defined as the presence of at least one symptom after 30 days of illness onset. A questionnaire for assessing general, cardiorespiratory, neuro-psychiatric, and gastro-intestinal symptoms was used to screen individuals with history of confirmed COVID-19. Data on demographics, HIV-related variables, comorbidities, and severity of COVID-19 were abstracted from electronic medical records. Univariate and multivariate logistic regression were used to identify risk factors for long-COVID.

Ninety-four PLHIV were screened for long-COVID. Median (interquartile range [IQR]) age was 51 (47-56) years and 73.4% were males. The majority (76.6%) had a history of asymptomatic-mild COVID-19 illness. The prevalence of long-COVID was 43.6% (95% confidence interval [CI], 33.4-54.2). Moderate-severe COVID-19 illness was significantly associated with long-COVID (adjusted odds ratio, 4.7; 95% CI, 1.4-17.9; p = .016). Among individuals with long-COVID, cough (22.3%) and fatigue (19.1%) were the commonest symptoms. The median (IQR) duration for resolution of symptoms was 15 (7-30) days. Ten individuals (10.6%) had persistent symptoms at a median of 109 days since the onset of COVID-19.

Long-COVID is common among PLHIV with moderate-severe acute COVID-19 illness. There is a need for integration of long-COVID diagnosis and care services within antiretroviral therapy clinics for PLHIV with COVID-19.

Despite advances in the field, the disease has proven to be increasingly complex to diagnose and management strategies are constantly evolving. Studies from 2020 have advanced the field even further, particularly with regard to new methods of diagnosis and monitoring, treatment of severe asthma, modifiable risk factors like exercise and obesity, aerosol delivery, and viral respiratory infections contributing to the development of asthma. Continued studies are needed to improve our care for children with asthma and we look forward to future advances. This article is part of our 2020 "Year in Review" series, in which we summarize publications in major topic areas, in the context of selected literature from other journals relevant to our discipline.
Isolated mediastinal and/or hilar lymphadenopathy (IMHL) has become an increasingly common finding as a result of the increased use of thoracic imaging modalities. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is accepted as the first step diagnostic method in the differential diagnosis of IMHL.

To determine the diagnostic yield of the procedure and to analyze clinical and sonographic findings that can be used to differentiate the etiology of lymph node pathologies.

Patients who underwent EBUS-TBNA procedure between March 2017 and March 2020 were included in this retrospective study. Demographic data, symptoms, comorbid diseases, and EBUS findings were obtained from the records of the patients.

EBUS-TBNA provided a diagnosis in 88 patients out of 120 patients (granulomatous diseases n=54, malignant diseases n=21, and anthracotic lymph nodes n=13), and 32 patients had a negative EBUS-TBNA. 22/32 negative EBUS-TBNA samples were true negatives (reactive lymphadenopathy). The sensitivity of the procedure was 89.8% while negative predict value was 68.7%, diagnostic yield of 91.6%. Patients with reactive lymph nodes had significantly more comorbidities (77.3%-19.4%, p < .001) and a lower number of lymph node stations (1.6 ± 0.8-2.7 ± 0.9, p < .001). Patients with anthracotic lymph nodes were older and mostly consisted of females (11/13, p < .001).

EBUS-TBNA has high-diagnostic efficiency in the differential diagnosis of IMHL. The number and size of lymph node stations can provide useful information for differential diagnosis. Clinical follow-up can be a more beneficial approach in patients with reactive and anthracotic lymph nodes before invasive sampling.
