Seed security is vital for food security. Rapid-cycle, climate-adaptive breeding programs and seed systems that deliver new, elite varieties to farmers to replace obsolete ones can greatly improve the productivity of maize-based cropping systems in sub-Saharan Africa (SSA). Despite the importance and benefits of accelerated varietal turnover to climate change adaptation and food security, the rate of maize varietal replacement in SSA is slow. This review outlines the major bottlenecks, drivers, risks, and benefits of active replacement of maize varieties in eastern and southern Africa (ESA) and highlights strategies that are critical to varietal turnover. Although there is an upsurge of new seed companies in ESA and introduction of new varieties with better genetics in the market, some established seed companies continue to sell old (over 15-year-old) varieties. Several recently developed maize hybrids in ESA have shown significant genetic gains under farmers' conditions. Empirical evidence also shows that timely replacement of old products results in better business success as it helps seed companies maintain or improve market share and brand relevance. Therefore, proactive management of product life cycles by seed companies benefits both the farmers and businesses alike, contributing to improved food security and adaptation to the changing climate.
Military service members carry the responsibility to maintain physical and psychological readiness. As such, it is critical for researchers to begin unravelling the widespread impact of the COVID-19 pandemic on service member's mental and physical wellbeing. The aim of this research was to investigate the complex relationships between BMI, physical activity, psychological stress and resilience among United States Air National Guardsmen (USANG), specifically during the pandemic.
An online survey was distributed to USANG members. The survey included measures of resilience (CD-RISC-25), perceived psychological stress (PSS), perceived psychological stress brought on by COVID-19 (COVID-19 PSL), current levels of physical activity (IPAQ-SF), perceived impact on physical activity brought on by COVID-19 (COVID-19 PAL), and BMI. Pearson's correlation coefficients (r) were used to assess correlation significance (
≤ 0.05), direction, and magnitude.
A total of 110 responses met inclusion criteria for data interpviour which subsequently might aid as a protective factor against psychological stress. Knowledge regarding the relationships between the aforementioned variables may help inform decisions by military leadership regarding future lockdowns.
COVID-19 pandemic is a serious health threating element throughout the world. One of the key elements to strengthen the body's immune system is to follow a healthy lifestyle to deal with health threating. The aim of this study was to evaluate the lifestyle components in COVID-19 patients.
This descriptive-analytical study carried on hospitalized COVID-19 patients from October 22, 2020 to January 19, 2021. Demographic characteristics, physical activity, nutritional status, stress and anxiety, and substance abuse were assessed. A simple model and multiple logistic regression model were used.
About 32% were hospitalized in the intensive care unit (ICU). Healthy lifestyle was observed only in 28%. About 82% had insufficient physical activity, and 67.3% was reported to be unfavorable in nutritional status. Severe stress and anxiety were observed in 30.4% of people. There were significant relationships between age (AOR = 2.11, p = 0.036), education (AOR = 0.35, p = 0.002) and a healthy lifestyle. A significant correlation was observed between ICU admission and unhealthy lifestyle (AOR = 0.40, p = 0.015).
Unhealthy lifestyle behaviors were seen in the most COVID-19 patients. Considering the significance of lifestyle changes could prove effective in reducing the risk of transmissible viral infections.

It is the most frequent ailment among women of all ages and races. The pain is dull and throbbing in character and occurs in the lower back and abdomen. Symptoms commonly appear 6 to 12 months after menarche, with the most significant incidence in the late teen and early twenties. Physical exercise is nearly a new non-medical intervention to relieve PD associated pain. Aerobics, stretching and Resistive exercises for 8-12 weeks, either supervised or unsupervised, relieves pain. Exercises are believed to cause hormonal changes in the uterine lining, which reduces PD symptoms. Researchers have presumed different pain-relieving methods, ranging from non-opioids to opioids to hormonal for variations in pain sensitivity. Exercise-induced analgesia provides the central pathway as the primary mechanism for pain reduction while, another way to reducing pain in PD may be a hormonal interaction. The hormonal changes causing exercise-induced pain modulation during the menstruation cycle is not clearly understood and the interaction and activation of all the central and endocrine components, which is a complex mechanism, is also not explained clearly. This study briefly reviews the physiological mechanism of Exercise-induced analgesia and its potent roles in controlling the pathogenesis of PD for pain relief.It's a saying "The early we start, the early we attain good health". Health is a state of complete physical, mental and social well-being and not merely absence of disease Fitness is an ability to execute daily functional activities with optimal performance, endurance, and strength to manage minimalist of disease, fatigue, stress and reduced sedentary behavior. In the modern era with advancement in technology, erosion of physical activity has drastically led to retardation in health and fitness. Hoods of luxurious and competition among students for scores/grades and professionals for promotions/incentives/benefits have deviated people from concentrating towards their health and putting it secondary. In 2016, across the globe, prevalence of physical inactivity was estimated at 27.5%, among adult population. To support further, in June 2018, WHO reported, 1 in five adults, and 4 of five adolescents to pose reduced physical activity. In the current ongoing pandemic era this scenario has been further negatively impacting the society to suffer from psychosocial, financial and economic loss, contributing to lack of physical activity. Health benefits of physical activity are not limited only to improved cardiorespiratory and muscular fitness, bone and cardiometabolic health, and positive effects on weight status, but it also boosts mental health and social health. Acknowledging the significance and urgency of decreasing insufficient physical activity globally, WHO endorsed a Global Action Plan on Physical Activity (GAPPA) at the World Health Assembly in 2018, wherein the member countries agreed to reach a new target of 15% relative reduction in insufficient physical activity among adolescents by 2030.The psychological aspect of dis-ease, which is indeed a lack of 'ease' is generally overlooked in the management of myriad maladies that affect the human body. The concept of mindfulness meditation, which is an interesting hybrid born from the meditative discipline of the east and the intellectual discipline of the west is gaining attention in the past two decades for its benefits in the holistic development of individuals. Thymidine DNA chemical When individuals with ailments are trained under therapists supervised by the clinicians, significant results can be seen in alleviating symptoms like pain, stress, anxiety and an improvement in the quality of life is observed. This review article focuses on the structure and basics of mindful meditation and the mechanisms of mindfulness and its positive effects on various diseases like lichen planus, urticaria, psoriasis, eczema, myofacial pain dysfunction syndrome, to name a few. There are various arenas within the discipline of oral and maxillofacial medicine where mindfulness-based techniques can be explored for its effectiveness in combating psychosomatic conditions. The article highlights the importance of holistic approach in treating diseases in which mindfulness meditation techniques play an important role.
Physical inactivity is a major global public health problem, with a large impact on morbidity and mortality. For this reason, knowledge and advice on physical activity (PA) should be common to all health professionals. In this context, the role of physicians stands out, because they act in the first contact and have a high potential in addressing this issue and its impact on health promotion, prevention, and treatment in chronic diseases. This study aims to observe the level of physical activity knowledge of medical students in a university in the south of Brazil.
A cross-sectional study was carried out by applying the short and validated version of the International Physical Activity Questionnaire (IPAQ) to collect data on sociodemographic factors, physical activity, knowledge of physical activity, and level of physical activity.
A total of 294 students were assessed. The average (± SD) age was 22.0 (± 3.3) years. Most were women, and 72.8% presented body mass index within the range 18.5-25 kg/m
. Results showed that 65.6% of the students practice physical activity. There was statistical difference regarding the level of physical activity (p < 0.001) and sitting time on weekdays (p = 0.031) between the groups of physically active and physically inactive individuals.
It was concluded that the practice of physical activity has no association with the level of knowledge about it. However, by practicing physical activities doctors are better able to motivate and encourage their patients.

We aimed to identify and describe different types of lifestyle interventions primarily or secondarily focused on weight loss in SLE patients.
A systematic search of controlled trials published until June 2021 that assigned adults patients after dietary or exercise intervention resulted in 248 studies initially screened.
Six studies with seven interventions (3 dietary and 4 exercise training programs) fulfilled the eligibility criteria and were included in the meta-analysis with a median of age 35.8 (31.3 to 49.0 years); median of BMI 26.6 (25.2 to 33.6 kg/m
). After six to twelve weeks of diet or exercise program, no differences were observed in body weight [-1.539 (-4.482 to 1.405) kg (CI 95%), p = 0.306]. Also, a subgroup analysis also revelated no body weight difference following dietary intervention [-3.561 (-9.604 to 2.481) kg (CI 95%), p = 0.248] or exercise intervention [-0.910 (-4.279 to 2.460) kg (CI 95%), p = 0.597].
The results showed that different protocols of exercise intervention or diets were not effective to reduce body weight in patients with SLE.
