Alex I Wiesman, Tony W Wilson
The ability to dynamically allocate neural resources within the visual space is supported by a number of spectrally-specific oscillatory responses, and such visuospatial processing has been found to decline moderately with age and differ by sex. However, the direct effects of age and sex on these oscillatory dynamics remains poorly understood. Using magnetoencephalography (MEG), structural magnetic resonance imaging, and advanced source reconstruction and statistical methods, we investigated the impact of aging and sex on behavioral performance and the underlying neural dynamics during visuospatial processing...

Background: Hip fracture is one of the most common problems in elderly that needs surgical repair. As, the majority of these patients have chronic diseases, they are at increased risk of peri-operative mortality and morbidity. The purpose of this study was to evaluate spinal anesthesia with bupivacaine vs bupivacaine in combination with lidocaine in terms of hemodynamic changes in patients undergoing hip fracture surgery. Methods: This double-blind clinical trial was conducted on 292 patients undergoing surgery for hip fracture under spinal anesthesia...

Soccer-induced fatigue and performance are different between the sexes. The effect of compression stockings (CS) use on fatigue during the soccer match in females is unknown. Thus, we evaluated the impact of CS use during a female soccer match on match-induced fatigue. Twenty soccer players were randomly allocated to two groups (n = 10 for each group): CS and Control (regular socks), and equally distributed within two teams. At rest (baseline 48-h before the match) and immediately post-match, we assessed agility T-test, standing heel-rise test and YoYo Intermittent Endurance Test level 2 (YoYoIE2) performance...

Tardive syndromes (TDS) typically manifest 3 months or later after exposure to antipsychotic drugs, and unfortunately have no satisfactory medical treatment. We explored the possibility of using therapeutic repetitive transcranial magnetic stimulation (rTMS). Twenty-six patients were allocated to receive real or sham rTMS over the hand/arm area of motor cortex (M1). Each received a daily total of 2000 rTMS pulses (20 Hz at 100% rMT: 1000 stimuli per hemisphere) for 10 consecutive days. Outcome was assessed using the Abnormal Involuntary Movement Scale (AIMS) and TMS measures of M1 excitability...

BACKGROUND: Polycystic ovary syndrome (PCOS) is a common condition characterized by hyperandrogenism, anthropometric changes (increased weight and waist-to-hip ratio [WHR]), behavioral changes (sexual dysfunction, anxiety, and depression), and reduced quality of life. Physical exercise may reduce many of the adverse effects of PCOS. However, no studies have yet evaluated the effects of aerobic exercise on the sexual function of women with PCOS. AIM: To compare the effects of continuous and intermittent aerobic physical training on the sexual function and mood of women with PCOS...

INTRODUCTION: Prior studies have shown that sex bias exists with subject enrollment in clinical trials, with more men being enrolled than women. The objective of this study was to identify if sex bias continues to exist in present day clinical trials entered into ClinicalTrials.gov . We hypothesize that males and females are not equally represented in recent clinical trials. MATERIALS AND METHODS: Data were abstracted from all interventional Phase I, II, and III clinical trials with adult subjects entered into ClinicalTrials...

Self-fertilization is widespread among simultaneously hermaphroditic animals and plants, but is often only facultatively deployed under circumstances that constrain outcrossing. A central prediction of sex allocation (SA) theory is that because exclusive selfing reduces sperm or pollen competition to zero, this should favour extreme economy in resources channelled to the male sex function. We can therefore expect that organisms switching from outcrossing to selfing should reduce their male allocation. However, to date this prediction has received relatively little support in animal taxa, especially compared to plants...

Widespread public health surveillance efforts focused on key populations (men who have sex with men, sex workers, people who inject drugs, and others) gather data on population sizes, HIV prevalence, and other information for planning and resource allocation. Biometric identification might improve this data gathering. However, in the context of extensive criminalisation of these populations, the use of biometrics such as fingerprints raises concerns that are insufficiently addressed in current policies. These concerns include infringing privacy, exposing participants to risks of legal action or violence, biasing surveillance results, and undermining trust in the health system...

The dynamics of stage-structured populations facing stage-specific variability in resource availability and/or demographic factors like unequal sex-ratios, remains poorly understood. We addressed these issues using a stage-structured individual-based model that incorporates life-history parameters common to many holometabolous insects. The model was calibrated using time series data from a 49-generation experiment on laboratory populations of Drosophila melanogaster, subjected to four different combinations of larval and adult nutritional levels...

Activation of the immune system induces rapid reductions in hypothalamic-pituitary-gonadal (HPG) axis activity, which in turn decreases secretion of sex steroids. This response is likely adaptive for survival by temporarily inhibiting reproduction to conserve energy; however, the physiological mechanisms controlling this response remain unclear. The neuropeptide kisspeptin is a candidate to mediate the decrease in sex hormones seen during sickness through its key regulation of the HPG axis. In this study, the effects of acute immune activation on the response to kisspeptin were assessed in male Siberian hamsters ( Phodopus sungorus )...

Unlike other disasters, injury rates after earthquakes are still on the rise at a global scale. With an estimated one million people injured by earthquakes in the last decade, the burden of injury is considerable. Importantly, the surgical procedures carried out by healthcare facilities are capable to avert part of this burden. Yet both burdens remain unquantified using understandable metrics. We explored in this analysis a method to calculate them using disability-adjusted life years (DALYs), an internationally accepted measure expressing years of healthy life lost due to a health condition...

In animals, sex differences in immunity are proposed to shape variation in infection prevalence and intensity among individuals in a population, with females typically expected to exhibit superior immunity due to life-history trade-offs. We performed a systematic meta-analysis to investigate the magnitude and direction of sex differences in immunity and to identify factors that shape sex-biased immunocompetence. In addition to considering taxonomic and methodological effects as moderators, we assessed age-related effects, which are predicted to occur if sex differences in immunity are due to sex-specific resource allocation trade-offs with reproduction...

Mohammad Asif, Aman Sai Guntreddy
Background: Tracheal intubation is usually facilitated by using a muscle relaxant to supplement drugs given for the induction of general anesthesia. Nondepolarizing muscle relaxants are also associated with the few disadvantages. Endotracheal intubation under volatile anesthetics without the use of muscle relaxants is possible, but it has disadvantages. Time available for intubation is much less when compared to the use of muscle relaxants. Considering the disadvantages of muscle relaxants and volatile agents in mind, there is a need for endotracheal intubation without muscle relaxants...

Background: Propofol has emerged as an induction agent of choice over the past two decades due to its quick, smooth induction and rapid recovery. The main concern for an anesthesiologist is the hemodynamic instability caused by the standard induction dose of propofol (2-3 mg/kg). Aim: We aim to study the efficacy of propofol auto-coinduction technique in comparison to the standard propofol induction technique in terms of the total induction dose requirement of propofol, the incidence of hemodynamic side effects and pain on injection, and the incidence of fentanyl-induced cough (FIC) in the absence of a synergistic agent like midazolam...

In polyandrous species, fathers benefit from attracting greater maternal investment toward their offspring at the expense of the offspring of other males, while mothers should usually allocate resources equally among offspring. This conflict can lead to an evolutionary arms race between the sexes, manifested through antagonistic genes whose expression in offspring depends upon the parent of origin. The arms race may involve an increase in the strength of maternally versus paternally derived alleles engaged in a "tug of war" over maternal provisioning or repeated "recognition-avoidance" coevolution where growth-enhancing paternally derived alleles evolve to escape recognition by maternal genes targeted to suppress their effect...

BACKGROUND: Comorbidity of drug use disorders (DUD) with other psychopathology is associated with worse functional and treatment outcomes than DUD alone. The present study sought to identify altered functional neural circuitry underlying DUD comorbidity with other psychiatric disorders, and model the relationship of these alterations to childhood trauma (Childhood Trauma Questionnaire) and negative self-beliefs (Beck Depression Inventory). METHODS: A sample of adult men and women (mean = 36...

BACKGROUND: The World Health Organization recommends all men who have sex with men (MSM) receive Hepatitis B Virus (HBV) and Hepatitis C Virus (HCV) testing. MSM in China are a high-risk group for HBV and HCV infection, but test uptake is low. Crowdsourcing invites a large group to solve a problem and then shares the solution with the public. This nationwide online randomized controlled trial will evaluate the effectiveness of a crowdsourced intervention to increase HBV and HCV testing among MSM in China...
