Male obesity has profound effects on morbidity and mortality, but relatively little is known about the impact of obesity on gametes and the potential for adverse effects of male obesity to be passed to the next generation. DNA methylation contributes to gene regulation and is erased and re-established during gametogenesis. Throughout post-pubertal spermatogenesis, there are continual needs to both maintain established methylation and complete DNA methylation programming, even during epididymal maturation. This dynamic epigenetic landscape may confer increased vulnerability to environmental influences, including the obesogenic environment, that could disrupt reprogramming fidelity. Here we conducted an exploratory analysis that showed that overweight/obesity (n = 20) is associated with differences in mature spermatozoa DNA methylation profiles relative to controls with normal BMI (n = 47).
We identified 3264 CpG sites in human sperm that are significantly associated with BMI (p < 0.05) using Infinium Huntial heritability of these DNA methylation alterations. If heritable, these changes have the potential to impede normal development.
People with HIV have always faced stigma and discrimination. Given the numerous papers that have addressed the psychological and social risk factors in spreading HIV, a pressing question is whether individuals' mere careless and behavioural flaws can still account for the spread of HIV. Barriers and opposing politic made a hard position for HIV and sex education in Iran.
The present study investigated the causes of contracting HIV/AIDS from the perspective of HIV-infected patients. To accomplish this, 150 patients referring to the voluntary counseling and testing Center, Shiraz were convenient selected based on the convenient sampling method and responded to a researcher-made questionnaire From June to August 2019. The data were analyzed through descriptive statistics (mean, SD, frequency tables) and inferential statistics (chi-square).
Results revealed that the main cause of HIV infection amongst males was the injection of narcotics, and in the females it was sexual intercourse with an infected individual. Meanwhile, 57% of the females and 66% of the males blamed themselves for contracting and transmitting the disease. The patients stated that if they could return to pre-infection period, they would use one of the following ways to prevent the disease (a) they would pay attention to hygienic/sanitary principles; (b) they would not get married; and (c) they would prevent drug addiction. Also only 44% of the individuals had successful siblings (those who were neither addicts nor HIV/AIDS-infected individuals), which was an observation that emphasizes on the epidemic of high-risk behaviors in the patients' families.
According to participants' statements collected in our study, weakness in governmental public health education, along with family-related and individual factors, are important causes of HIV spread.

Post-Infectious Neurological Syndromes (PINS) are heterogeneous neurological disorders with post or para-infectious onset. PINS diagnosis is complex, mainly related to the absence of any recognized guidelines and a univocal definition.
To elaborate a diagnostic guide for PINS.
We retrospectively analysed patients younger than 14 years old admitted to Bambino Gesù Children's Hospital in Rome for PINS from December 2005 to March 2018. Scientific literature using PubMed as research platform was analysed the key words "Post-Infectious Neurological Syndromes" were used.
A polysymptomatic presentation occurred in a percentage of 88% of the children. Motor signs and visual disturbances the most observed symptoms/signs were the most detached, followed by fever, speech disturbances, sleepiness, headache and bradipsychism. Blood investigations are compatible with inflammation, as a prodromal illnesses was documented in most cases. RKI1447 Normal cerebral spinal fluid (CSF) characteristics has been found in the majority of the study population. Magnetic resonance imaging (MRI) was positive for demyelinating lesions. Antibiotics, acyclovir and steroids have been given as treatment.
We suggest diagnostic criteria for diagnosis of PINS, considering the following parameters neurological symptoms, timing of disease onset, blood and CSF laboratory tests, MRI imaging.
We propose criteria to guide clinician to diagnose PINS as definitive, probable or possible. Further studies are required to validate diagnostic criteria.

Assessing the risk of post-surgical mortality is a key component of pre-surgical planning. The Surgical Outcome Risk Tool (SORT) uses pre-operative variables to predict 30-day mortality. The aim of this study was to externally validate SORT in patients undergoing major abdominal surgery.
Data were collected from patients treated in five independent hospitals in the UK. Individualised SORT scores were calculated, and area under the receiver operating characteristic (AUROC) and precision-recall curves (PRC) plus 95% confidence intervals (CI) were drawn to test the ability of SORT to identify in-hospital death. Outcomes of patients with a SORT predicted risk of mortality of ≥ 5% (high risk) were compared to those with a predicted risk of < 5% (standard risk).
The study population comprised 3305 patients, mean age 51 years, 2783 (84.2%) underwent elective surgery most frequently involving the colon (24.6%), or liver, pancreas or gallbladder (18.2%). Overall, 1551 (46.9%) patients were admitted to ICU and 29 (0.88%) died. The AUROC of SORT for discriminating patients at risk of death in hospital was 0.899 (95% CI 0.849 to 0.949) and the PRC 0.247. In total, 72 (2.18%) patients were stratified as high risk. There were more unplanned ICU admissions and deaths in this group compared to the standard risk group (25.0% and 3.3%, versus 3.1% and 0.5%, respectively).
We externally validated SORT in a large population of abdominal surgery patients. SORT performed well in patients with lower risk profiles, but underpredicted adverse outcomes in the higher risk group.

Systemic lupus erythematosus (SLE) is a complex and challenging autoimmune disease. Severe acute respiratory syndrome coronavirus 2 (SARS‑CoV‑2) is a novel viral agent that can cause a life-threatening respiratory disorder named coronavirus disease 2019 (COVID‑19). Association between SARS‑CoV‑2 and SLE is not clear. We reported the first case of SLE manifestation following COVID-19.
A 39-year-old Iranian/Persian man with complaints of fever, scaling on the palms of the hands and feet, lower extremity edema, and ankle swelling was referred to Kashan Rheumatology Clinic in 2020. He was infected with SARS-CoV-2 2months ago. The patient had proteinuria and was positive for SLE laboratory tests. After one week of treatment with prednisolone (30mg daily) and hydroxychloroquine, paresthesia, proteinuria, and edema continued. The patient was treated with pulse methylprednisolone (1000 mg for three consecutive days), gabapentin, and vitamin B (300mg daily), which reduced paresthesia.
This is the first case of SLE manifestation following COVID-19. SARS-CoV-2 may produce autoantibodies or develop the clinical features of subclinical SLE.

Sepsis is a life-threatening condition accompanied by organ dysfunction subsequent to a dysregulated host response to infection. Up to 60% of patients with sepsis develop acute kidney injury (AKI), which is associated with a poor clinical outcome. The pathophysiology of sepsis-associated AKI (sepsis-AKI) remains incompletely understood, but mitochondria have emerged as key players in the pathogenesis. Therefore, our aim was to identify mitochondrial damage in patients with sepsis-AKI.
We conducted a clinical laboratory study using "warm" postmortem biopsies from sepsis-associated AKI patients from a university teaching hospital. Biopsies were taken from adult patients (n = 14) who died of sepsis with AKI at the intensive care unit (ICU) and control patients (n = 12) undergoing tumor nephrectomy. To define the mechanisms of the mitochondrial contribution to the pathogenesis of sepsis-AKI, we explored mRNA and DNA expression of mitochondrial quality mechanism pathways, DNA oxidation and mitochondrial DNA (mitochondrial quality control mechanisms, which likely resulted in a reduction in mitochondrial mass.
Sepsis-AKI induces mitochondrial DNA damage in the human kidney, without upregulation of mitochondrial quality control mechanisms, which likely resulted in a reduction in mitochondrial mass.
MicroRNAs have been reported to participate in tumorigenesis, treatment resistance, and tumor metastasis. Novel microRNAs need to be identified and investigated to guide the clinical prognosis or therapy for breast cancer.
The copy number variations (CNVs) of MIR3613 from Cancer Genome Atlas (TCGA) or Cancer Cell Line Encyclopedia (CCLE) were analyzed, and its correlation with breast cancer subtypes or prognosis was investigated. The expression level of miR-3613-3p in tumor tissues or serum of breast cancer patients was detected using in situ hybridization and qPCR. Gain-of-function studies were performed to determine the regulatory role of miR-3613-3p on proliferation, apoptosis, and tumor sphere formation of human breast cancer cells MDA-MB-231 or MCF-7. The effects of miR-3613-3p on tumor growth or metastasis in an immunocompromised mouse model of MDA-MB-231-luciferase were explored by intratumor injection of miR-3613-3p analogue. The target genes, interactive lncRNAs, and related signaling pathways of miR-3613-3p were identified by bioinformatic prediction and 3'-UTR assays.
We found that MIR3613 was frequently deleted in breast cancer genome and its deletion was correlated with the molecular typing, and an unfavorable prognosis in estrogen receptor-positive patients. MiR-3613-3p level was also dramatically lower in tumor tissues or serum of breast cancer patients. Gain-of-function studies revealed that miR-3613-3p could suppress proliferation and sphere formation and promote apoptosis in vitro and impeded tumor growth and metastasis in vivo. Additionally, miR-3613-3p might regulate cell cycle by targeting SMS, PAFAH1B2, or PDK3 to restrain tumor progression.
Our findings indicate a suppressive role of miR-3613-3p in breast cancer progression, which may provide an innovative marker or treatment for breast cancer patients.
