Obesity is now recognised as an emerging public health problem across the globe. Its incidence has been growing in the last two decades. Furthermore, as per the obesity treatment guidelines, a comprehensive approach that incorporates behavioural treatment, medications, lifestyle modifications, and/or bariatric surgery is the best way to manage weight. A novel dual agonist of Glucose-dependent insulinotropic peptide (GIP) and Glucagon-like peptide -1 (GLP-1) receptors, Tirzepatide, was recently approved for the management of obesity. Tirzepatide manages blood sugar levels and enhances weight loss more than GLP-1 receptor agonists.

The COVID-19 pandemic impacted all areas of daily life, including medical care. Unfortunately, to date, no specific treatments have been found for the cure of this disease, and therefore, it is advisable to implement all possible strategies to prevent infection. In this context, it is important to better define the role of all behaviors, in particular nutrition, in order to establish whether these can both prevent infection and improve the outcome of the disease in patients with COVID-19. There is sufficient evidence to demonstrate that immune response can be weakened by inadequate nutrition. Nutrition management and treatment are very important to enhance the immune response of an infected person against RNA viral infection. A complete nutritional assessment should include anthropometric, dietary, and laboratorial assessment, as well as a multidisciplinary discussion about the patient's clinical condition. In this way, it is possible to establish an individualized nutritional approach to contribute to improving clinical and nutritional prognoses. From this point of view, diet, through intake of vitamins and trace elements and maintaining adequate functioning of the intestinal barrier, can reduce the severity of the COVID-19 infection. In this study, we provide an overview of the effects of diet on COVID-19 infection in non-cancer patients. This notion needs to be further evaluated, and thus, identification, characterization, and targeting of the right nutrition principles related to the management of patients with COVID-19 are likely to improve outcomes and may prevent the infection or lead to a cure.

Diabetes mellitus is a common chronic metabolic disease characterized by a high incidence and disability rate. Intestinal flora refers to the microbial community that lives in the intestines and plays a crucial role in maintaining intestinal health and the human immune system. In recent years, an increasing body of research has revealed a close relationship between intestinal flora and diabetes. The pathophysiological mechanisms between them have also been constantly uncovered, and the regulation of intestinal flora has shown promising efficacy in the adjuvant treatment of diabetes. This study mainly summarized the characteristics and mechanisms of intestinal flora in patients with diabetes in recent years, as well as the methods of regulating intestinal flora to prevent and treat diabetes, and prospected the future research direction. This will offer a theoretical basis for the clinical adjuvant treatment of diabetes with intestinal flora and the development of new drugs.

Lung cancer and tuberculosis (TB) are classified as the second-most life-threatening diseases globally. They both are exclusively represented as major public health risks and might exhibit similar symptoms, occasionally diagnosed simultaneously. Several epidemiological studies suggest that TB is a significant risk factor for the progression of lung cancer. The staggering mortality rates of pulmonary disorders are intrinsically connected to lung cancer and TB. Numerous factors play a pivotal role in the development of TB and may promote lung carcinogenesis, particularly among the geriatric population. Understanding the intricacies involved in the association between lung carcinogenesis and TB has become a crucial demand of current research. Consequently, this study aims to comprehensively review current knowledge on the relationship between tuberculosis-related inflammation and the emergence of lung carcinoma, highlighting the impact of persistent inflammation on lung tissue, immune modulation, fibrosis, aspects of reactive oxygen species, and an altered microenvironment that are linked to the progression of tuberculosis and subsequently trigger lung carcinoma.

In this study, we examined preexisting systemic inflammation before COVID-19 (SIC), as assessed through C-reactive protein (CRP) levels, to gain insights into the origins of acute kidney injury (AKI) in adults with comorbidities affected by COVID-19. Although aging is not categorized as a disease, it is characterized by chronic inflammation, and older individuals typically exhibit higher circulating levels of inflammatory molecules, particularly CRP, compared to younger individuals. Conversely, elevated CRP concentrations in older adults have been linked with the development of comorbidities. Simultaneously, these comorbidities contribute to the production of inflammatory molecules, including CRP. Consequently, older adults with comorbidities have higher CRP concentrations than their counterparts without comorbidities or those with fewer comorbidities. Given that CRP levels are correlated with the development and severity of AKI in non-COVID-19 patients, we hypothesized that individuals with greater SIC are more likely to develop AKI during SARS-CoV-2 infection than those with less SIC.

Hypoglycaemia in individuals with diabetes is defined as the presence of signs or symptoms in addition to potentially occurring abnormal plasma glucose levels in the patient. Munchausen Syndrome (MS) is characterized by the deliberate induction of physical or psychological symptoms or the act of pretending to have symptoms. Patient reports of this factitious disease pattern are limited in the literature. The diagnosis and treatment of this syndrome, which is among factitious disorders, is very difficult. Endocrinological complaints are very common among those admitted to the hospitals.
