Correlation of pre-existing comorbidities with disease severity in individuals infected with SARS-COV-2 virus.

Shortly after the first publication on the new disease called Coronavirus Disease 2019 (Covid-19), studies on the causal consequences of this disease began to emerge, initially focusing only on transmission methods, and later on its consequences analyzed in terms of gender, age, and the presence of comorbidities. The aim of our research is to determine which comorbidities have the greatest negative impact on the worsening of the disease, namely which comorbidities indicate a predisposition to severe Covid-19, and to understand the gender and age representation of participants and comorbidities. The results of our study show that the dominant gender is male at 54.4% and the age of 65 and older. The most common comorbidities are arterial hypertension, diabetes mellitus, and cardiovascular diseases. The dominant group is recovered participants aged 65 and older, with comorbidities most frequently present in this group. The highest correlation between patients with different severity of the disease was found with cardiovascular diseases, while the coefficient is slightly lower for the relationship between patients with different disease severity and urinary system diseases and hypertension. According to the regression analysis results, we showed that urinary system diseases have the greatest negative impact on the worsening of Covid-19, with the tested coefficient b being statistically significant as it is 0.030 < 0.05. An increase in cardiovascular diseases affects the worsening of Covid-19, with the tested coefficient b being statistically significant as it is 0.030 < 0.05. When it comes to arterial hypertension, it has a small impact on the worsening of Covid-19, but its tested coefficient b is not statistically significant as it is 0.169 > 0.05. The same applies to diabetes mellitus, which also has a small impact on the worsening of Covid-19, but its tested coefficient b is not statistically significant as it is 0.336 > 0.05. Our study has shown that comorbidities such as urinary system diseases and cardiovascular diseases tend to have a negative impact on Covid-19, leading to a poor outcome resulting in death, while diabetes mellitus and hypertension have an impact but without statistical significance.

Biochemical and Hematological Profile of Covid-19 Patients on Mechanical Ventilation.

Beakground: The prevalence of cardiovascular diseases in COVID-19 patients, such as hypertension, diabetes mellitus, and chronic obstructive pulmonary disease, which are the most common comorbid conditions in COVID-19 patients, is considered a risk factor for premature mortality in the population. The aim of the study is to compare the standard biochemical and hematological markers of COVID-19 patients on mechanical ventilation and those who have recovered, and to identify differences by gender and comorbidities, as well as the dominant marker in comorbidities that frequently shows statistical significance, in order to investigate its prognostic value in further research. METHODS: The study is a retrospective study of patients with RT-PCR confirmed presence of the Sars-CoV-2 virus who were hospitalized at the Zenica Cantonal Hospital. The study lasted from February to April 2021. RESULTS: The results of the study, which included a sample of 302 participants, indicate that men were more represented in both the mechanical ventilation group and the recovered group, with 59.6% compared to women with 40.4%. Among the investigated biochemical and hematological parameters, there was a significantly higher number of leukocytes, urea, creatinine, LDH, and troponin in patients on mechanical ventilation, while the number of platelets was significantly higher in recovered patients. The most common comorbidity was hypertension in both groups of patients, with 24.5%. In patients on mechanical ventilation with cardiovascular disease, there was a significantly higher number of leukocytes, urea, creatinine, LDH, and troponin. In the same patients with three comorbidities, there was a significantly higher number of leukocytes, troponin, and LDH, while recovered patients without comorbidities had a significantly higher number of platelets. CONCLUSIONS: The male gender and comorbidities remain a vicious circle in COVID-19 infection, while biochemical and hematological markers can help in forecasting and improve the clinical treatment of these high-risk patients.

PREDICTORS OF SEXUAL SATISFACTION: AN INTERNATIONAL STUDY.

The aim of this cross-cultural study was to examine predictors of sexual satisfaction. For the present analysis, we used a large-scale sample database that included 8821 individuals from 4 countries. All participants completed the same questionnaires, which were designed to capture numerous important variables that have been shown to correlate with sexual satisfaction. According to our results, predictors of sexual satisfaction were classified into four general categories (demographic factors, psychological factors, sociocultural factors, and pathophysiological factors). Our international study found statistically significantly higher satisfaction among homosexual participants, participants aged 18 to 23 years, those with a higher level of education, in a relationship, with a current sexual partner, in a current partnered (unmarried) relationship, and without a diagnosed sexual or mental disorder. At the same time, we found that the correlation between sexual satisfaction and the different predictors varieed considerably across countries, which calls for further research.

Total and partial clinical inertia of general physicians with type 2 diabetes mellitus patients in Central Bosnia Canton.

BACKGROUND: The goal of this study was to determine the frequency and predictive factors of partial (PCI) and total clinical inertia (TCI) of general physicians (GPs) in Central Bosnia Canton in the care of type 2 diabetes mellitus patients. MATERIAL AND METHODS: A longitudinal study was conducted with a prospective data collection. Total of 541 subjects of over 40 years of age with type 2 diabetes mellitus of both genders were included in the study. Total of 532 subjects completed the study. Questionnaires for physicians and patients and the Perceived Stress Scale were used, as well as anthropometric measurements and measurements of the glucose level in plasma, HbA1c, triglycerides, AST, ALT, creatinine and eGFR, which were examined on the day of study entry, after 6 months and after one year. RESULTS: TCI was 5.8% and PCI was 25.6%. Patients with poorly regulated glycaemia and elevated triglyceride levels had the highest probability of PCI and TCI. Patients with an unaccomplished targeted level of blood pressure were more likely to experience PCI. Patients treated by both an internist and a general physician were more likely to have TCI as compared to patients treated only by an internist. CONCLUSIONS: Patients with poor glycemic control experience PCI and TCI more often. In our study, referring to a diabetologist was observed as a non-inert procedure, which resulted in lower PCI and TCI, compared to studies where clinical inertia was defined only as non-intensification of medication therapy.

Determination of Six Sigma Metric in Control of Enzymes Determination in Human Serum.

BACKGROUND: Clinical Chemistry is the backbone of medical treatment, diagnostics, and prevention. The laborato-ries are trying to improve the quality and to reduce diagnostic errors and processing time and safeguard trace-ability of all laboratory procedures to ensure patient safety. Six sigma belongs to statistical quality control and provides a new methodology for measuring and improving process performance in laboratory. METHODS: Activities of AST, ALT, CK, LDH, Amy, and γ-GT were determined by standard kinetic methods on a Vitros 5600 biochemistry analyzer. Two daily quality controls (Verifier I and Verifier II) were run over 60 days. Total percent CV was calculated from routine daily QC. Between-instrument bias was also calculated from daily QC. RESULTS: The calculated sigma metrics for AST were 6.9 and 3.8; for ALT 9.3 and 5.6; for CK 6.6 and 5.3; LDH 5.2 and 5.2; for γ-GT 4.9 and 2.7; and for amylase 8.7 and 7.1. Analytical performance for AST, ALT, CK, LDH, and Amylase is world class. On the other hand, γ-GT analytical performance is poor. CONCLUSIONS: Six Sigma benefits from earlier quality management approaches that creates new challenges for medical laboratories.

Clinical Inertia in Type 2 Diabetes Patients in Primary Health Care Clinics in Central Bosnia.

BACKGROUND The goal of this research was to determine the frequency of clinical inertia of general practice physicians in the region of Central Bosnia in healthcare for type 2 diabetes patients, to analyze characteristics of patients and physicians, as well as glucose regulation during clinical inertia, and, on the basis of these indicators, give recommendations for reducing clinical inertia. MATERIAL AND METHODS This study included 29 doctors, family physicians, or general practitioners, who collected data in a total sample of 541 type 2 diabetes mellitus patients from July to November 2017. The research was conducted using 2 questionnaires. The glucose concentration in plasma and the percentage of glycosylated hemoglobin (HbA1c) were determined. Concertation of cholesterol, triglycerides, AST, and ALT were also measured. After the collection, new data were processed and the degree of clinical inertia was determined. RESULTS Levels of HbA1c ranged from 4.3% to 13.0%, and 38.4% of all patients had HbA1c level higher than 7.5%, while 8.3% of them had HbA1c level 9.0% or higher. Clinical inertia in our research was 12.6% out of all patients and 48.2% were referred to a specialist by their doctor. CONCLUSIONS For better regulation of glycemia and reduction of clinical inertia with type 2 diabetes patients, more specialized training is needed for selected physicians. Strengthening of primary healthcare and encouraging doctors to perform procedures can contribute to better outcomes of treatment, lower clinical inertia, and better education of patients.
