Weight Management on the Level of Primary Healthcare
Obesity is a complex disease that, like COVID-19, has reached pandemic proportions. Consequently, it has become a rapidly growing scientific field, represented by an extensive body of research publications.

Weight Loss
Overweight and obesity are related pathological conditions with a significant impact at the cardiovascular, metabolic, musculoskeletal, and oncological levels, representing a significant global public health problem. The traditionally proposed therapeutic approaches act at the nutritional, psychological, lifestyle (abolishing sedentary lifestyle and promoting physical exercise), and pharmacological levels, in combination with the consumption of food supplements.

Vitamin D—Innate and Acquired Immunity
Globally, vitamin D deficiency is a significant public health problem—a pandemic—that has overtaken iron deficiency as the most common nutritional deficiency in the world. Vitamin D deficiency is associated with many chronic diseases and increases the risk of acute and worsened chronic infections. Both vitamin D and [25(OH]D: calcifediol) and its active form, 1,25-dihydroxyvitamin D [1,25(OH)2D: calcitriol], play critical roles in protecting humans from invasive pathogens, reducing risks of autoimmunity, and maintaining better health. Conversely, low 25(OH)D status increases susceptibility to infections and developing autoimmunity. Individuals obtain optimal results by maintaining serum 25(OH)D concentrations above 50 ng/mL (125 nmol/L) (above 40 ng/mL in the population): this also minimizes community outbreaks and autoimmune disorders. In over 97.5% of people, this can be achieved through daily sun exposure (except in countries far from the equator during winter) or taking between 5,000 and 8,000 IU vitamin D supplements daily (average, ~70 to 90 IU/kg body weight). Only those with gastrointestinal malabsorption, obesity, or on medications that increase catabolism of vitamin D, and a few specific disorders require higher intake.

Viral Zoonotic Diseases and Male Reproduction
Zoonotic diseases occur as a result of human interactions with animals with the inadvertent transmission of pathogens from one to another. Zoonoses remain a major cause of morbidity and mortality among human populations, as they have been a source of pandemics in human history. Viral zoonoses account for a significant percentage of pathogens of zoonotic sources, posing a huge risk to men’s general health and fertility. Evidence from reviewed articles showed that viral zoonotic diseases elicit an immune reaction that induces inflammatory mediators and impairs testicular functions such as spermatogenesis and steroidogenesis, leading to abnormal semen parameters that lead to subfertility/infertility. Although most zoonotic viruses linger in semen long after recovery, their presence in semen does not directly translate to sexual transmission.

Types of Breast Cancer Imaging
Cancer is an incurable disease based on unregulated cell division. Breast cancer is the most prevalent cancer in women worldwide, and early detection can lower death rates. Medical images can be used to find important information for locating and diagnosing breast cancer. The best information for identifying and diagnosing breast cancer comes from medical pictures.

Third-Generation Antipsychotics and Lurasidone in Substance-Induced Psychoses Treatment
Substance-induced psychosis (SIP) is a psychiatric condition triggered by substance misuse or withdrawal, characterized by unique features distinct from those of primary psychotic disorders. These distinctive features include a heightened prevalence of positive symptoms, such as hallucinations and delusions, in addition to a spectrum of mood and cognitive disturbances.

The Microbiome and Cancer Development
Changes in the microbiome also induce complex changes in human cells. From a biological perspective, the normal cervicovaginal microbiome is composed mainly of Lactobacillus spp., thus exhibiting low bacterial diversity and protecting against carcinogenesis through various mechanisms. The lactobacilli secrete lactic acid, and the low vaginal pH promotes healthy local homeostasis. The lactobacilli also secrete cytokines, antimicrobial peptides, and other metabolites that protect the local epithelium. They promote a healthy level of physiological inflammation that stimulates the immune system to fight against pathogens. On the other hand, the dysbiotic cervicovaginal microbiome exhibits a high diversity of microorganisms, primarily obligate and strict anaerobes, that lead to a high vaginal pH. The bacteria promote the disruption of the epithelial barrier and secrete various metabolites and enzymes such as sialidase, proinflammatory cytokines and chemokines, reactive oxygen species, and other carcinogenic metabolites that lead to chronic inflammation and a dysregulated local metabolism. Further down the line, they also lead to genotoxicity and genomic instability, as well as altered proliferation and altered apoptosis. The dysbiotic environment also promotes angiogenesis. The chronic inflammation activates immune cells that secrete even more proinflammatory cytokines and chemokines such as Interleukin (IL)-6, IL-8 or Tumor necrosis factor (TNF), resulting in even more reactive oxygen species that further promote carcinogenic mechanisms. Hence, there are many different mechanisms through which the microbiota can impact carcinogenesis.

The Influence of Heavy Metal
There are a multitude of sources of heavy metal pollution which have unwanted effects on this super organism, the soil, which is capable of self-regulation, but limited. Living a healthy life through the consumption of fruits and vegetables, mushrooms, edible products and by-products of animal origin, honey and bee products can sometimes turn out to be just a myth due to the contamination of the soil with heavy metals whose values, even if they are below accepted limits, are taken up by plants, reach the food chain and in the long term unbalance the homeostasis of the human organism. Plants, these miracles of nature, some with the natural ability to grow on polluted soils, others needing a little help by adding chelators or amendments, can participate in the soil detoxification of heavy metals through phytoextraction and phytostabilization.
