ABSTRACT

OBJECTIVE: Aim: To study the risk factors in patients with prediabetes that can lead to the progression of impaired glucose tolerance in the form of type 2 diabetes mellitus.

PATIENTS AND METHODS: Materials and methods: The selection of patients for this study was carried out on an outpatient basis at the Department of Therapy and Family Medicine, Uzhhorod National University. Patients with prediabetes were identified based on the American Diabetes Association criteria. Informed consent was obtained from all patients before the start of the study. Patients were randomly assigned to one of two groups: Group 1 (n=37) that received typical treatment according to the recommendations of the American Diabetes Association and the control Group 2 (n=42). At the 3rd year of the study, we determined the body mass index, glucose levels and glycated hemoglobin levels of the patients, also their medical documentation was analyzed and patients were interviewed about concomitant diseases.

RESULTS: Results: Analyzing the 3-year follow-up of patients with prediabetes, cases of type 2 diabetes mellitus were detected in both groups, but there is no statistically significant difference when comparing the indicators between the groups (p>0.05).

CONCLUSION: Conclusions: In our study, we analyzed the risk factors in patients with prediabetes that can lead to type 2 diabetes. During a 3-year follow-up, we identified cases of type 2 diabetes mellitus.

ABSTRACT

OBJECTIVE: Aim: The investigation of health professionals’ burnout and depression, working in refugees’ reception centers and their possible intercorrelation.

PATIENTS AND METHODS: Materials and methods: A descriptive correlation study was carried out in health professionals, who worked in refugees’ reception centers and accommodation programs throughout Greece. Data were collected using an anonymous questionnaire through online Google Forms. The questionnaire contained demographics, the Copenhagen Burnout Questionnaire (CBI-Gr) and the Patient Health Questionnaire (PHQ-9). The SPSS 22.00 was used for the statistical analysis and the significance level was set at 0.05.

RESULTS: Results: The sample consisted of 125 healthcare professionals working in refugees’ reception centers and accommodation programs, the majority of tchem were women (62.4%), aged between 30-39 years (39.2%) nurses (24.8%) and with a master’s degree (28%). A strong linear positive correlation was found between depression and burnout (r=0.542, p=0.000). A statistically significant correlation was also recorded between burnout and female gender (p=0.001), the age group of 30-39 (p=0.042) and nursing profession (p=0.003).

CONCLUSION: Conclusions: A strong linear relationship between burnout and depression was revealed, a finding indicating that it is imperative to implement interventions to strengthen the resilience of health professionals working in refugees’ reception centers.

ABSTRACT

OBJECTIVE: Aim: Determination of factors associated with frailty syndrome (FS) in patients with heart failure (HF).

PATIENTS AND METHODS: Materials and methods: Consecutive patients hospitalized in the department were assessed for the presence of FS using L. Fried criteria, Edmonton Frail Scale (EFS) and Tilburg Frailty Indicator (TFI). Presence of arterial hypertension, diabetes, obesity, chronic obstructive pulmonary disease (COPD), and heart failure was included in the analysis based on patients’ medical history and findings from current hospitalization. Patients were assessed for the presence of depression using Beck’s Depression Inventory (BDI). Physical capacity was assessed using NYHA classification.

RESULTS: Results: 87 patients (mean age 81.4±6.7; 57 women; 11 HFrEF, mean NYHA 2.36±1.21; 11 HFmrEF, mean NYHA 2.18±1.08; 65 HFpEF mean NYHA 1.94±1.09) were included in the analysis. Multivariable analysis showed significant relationship between FS assessed with EFS and age (β=0.316, SE=0.08; p=0.0001), arterial hypertension (β=-0.194, SE=0.08; p=0.0173), COPD (β=0.176, SE=0.08; p=0.0300) and depression (β=0.565, SE=0.08; p=0.0000). FS assessed with L. Fried criteria was significantly related to age (β=0.359, SE=0.09; p= 0.0001), NYHA classification (β= 0.336, SE=0.09; p=0.0002) and depression (β=0.297, SE=0.09; p=0.0010). Age (β=0.251, SE=0.10; p=0.0114) and depression (β=0.375, SE=0.1; p=0.0002) were significantly related to FS assessed using TFI. In multivariable analysis HF phenotype was not significantly related to FS.

CONCLUSION: Conclusions: Age and depression assessed with BDI are related to FS in patients with HF. Arterial hypertension and COPD are linked to FS assessed using EFS, whereas NYHA classification is linked to FS assessed with L. Fried criteria. No statistically significant relationship was found between FS and HF phenotype.

ABSTRACT

OBJECTIVE: Aim: To evaluate primary health physicians’ clinical and behavioral practices towards antibiotics administration in a specific region in Greece.

PATIENTS AND METHODS: Materials and methods: A cross sectional study was conducted using a questionnaire in all structures of primary health care (PHC) of the Peloponnese Region. The study was conducted in May-October 2020.

RESULTS: Results: In total, 306 out of 404 primary healthcare physicians completed the questionnaire (response rate of 75.8%). Our results showed that most of physicians used to prescribing antibiotics empirically in common diseases, except for the prevention of secondary respiratory tract infection. Overall, 66.3% answered that they do not feel diagnostic uncertainty that would lead them to prescribe antibiotics. Approximately 40% of the physicians stated an increase on antibiotics use and patients demand for antibiotic prescribing, however 71.4% “rarely/never” affected by this requirement. 51.9% of the sample used to prescribed brand name antibiotics. Statistically significant differences were found between demographic and professional characteristics, and physicians’ clinical and behavioral practices (p≤ 0.05).

CONCLUSION: Conclusions: Our findings could provide decision makers with information on how to manage antibiotic prescribing in primary health care in the country, focusing mainly on the use of specific diagnostic tests as well as relevant guidelines and protocols for changing prescription behavior.

ABSTRACT

BACKGROUNDAND OBJECTIVES: Despite being preventable, neonatal hypothermia remains common. We hypothesized that the proportion of newborns with hypothermia on admission would be high in all settings, higher in hospitals in middle-income countries (MIC) compared with high-income countries (HIC), and associated with morbidity and mortality.

METHODS: Using the Vermont Oxford Network database of newborns with birth weights 401 to 1500 g or 22 to 29 weeks’ gestational age from 2018 to 2021, we analyzed maternal and infant characteristics, delivery room management, and outcomes by temperature within 1 hour of admission to the NICU in 12 MICs and 22 HICs.

RESULTS: Among 201 046 newborns, hypothermia was more common in MIC hospitals (64.0%) compared with HIC hospitals (28.6%). Lower birth weight, small for gestational age status, and prolonged resuscitation were perinatal risk factors for hypothermia. The mortality was doubled for hypothermic compared with euthermic newborns in MICs (24.7% and 15.4%) and HICs (12.7% and 7.6%) hospitals. After adjusting for confounders, the relative risk of death among hypothermic newborns compared with euthermic newborns was 1.21 (95% confidence interval 1.09-1.33) in MICs and 1.26 (95% confidence interval 1.21-1.31) in HICs. Every 1°C increase in admission temperature was associated with a 9% and 10% decrease in mortality risk in MICs and HICs, respectively.

CONCLUSIONS: In this large sample of newborns across MICs and HICs, hypothermia remains common and is strongly associated with mortality. The profound burden of hypothermia presents an opportunity for strategies to improve outcomes and achieve the neonatal 2030 Sustainable Development Goal.

ABSTRACT

Differentiating between thyroid and parathyroid lesions by means of ultrasound can be a challenge in some cases. This study explores the diagnostic efficacy of bidimensional shear wave elastography planewave ultrasound (2D SWE PLUS) as an auxiliary technique in distinguishing these superficial structures. We evaluated 86 cases, presenting with concurrent thyroid nodules and hyperparathyroidism, through conventional ultrasound and 2D SWE PLUS, employing an Aixplorer Supersonic Mach30 with a 5-18 MHz linear probe. Statistically significant differences were observed for the elasticity index (EI) between parathyroid and normal thyroid tissue (p<0.0001, U=291), and between parathyroid lesions and thyroid nodules (p<0.0001, U=248.5). An area under the curve (AUC) of 0.961, with an optimal cut-off value of ≤8.9 kPa, was established to effectively distinguish parathyroid tissue from normal thyroid tissue (sensitivity of 91.9%; specificity of 97.5%). Furthermore, an AUC of 0.963 and an optimal cut-off of 9.24 kPa (sensitivity of 94.2%, specificity of 91.1%) were determined for parathyroid vs thyroid lesions. Elasticity values were significantly elevated in the cancer group compared to benign thyroid nodules (p<0.0001). Our findings suggest that 2D SWE PLUS is an effective tool in differentiating between thyroid nodules and parathyroid lesions, enhancing diagnostic performance in neck ultrasonography.

ABSTRACT

BACKGROUND/AIMS: Antimicrobial de-escalation (ADE) remains a challenging strategy in the treatment of pneumonia. We investigated the outcomes of ADE as measured by mortality and duration of the use of antibiotics in patients with culture- negative pneumonia.

METHODS: We performed a systematic review and meta-analysis in accordance with PRISMA guidelines. The primary outcome was inpatient mortality.

RESULTS: We examined six studies comprising 11,933 subjects, of whom 1,152 received ADE. Overall, the ADE strategy was associated with a statistically lower risk of in-hospital mortality compared with non-ADE (risk ratio [RR] = 0.60, 95% confidence interval [CI] = 0.38 to 0.93). Although substantial heterogeneity was found among the included studies (I2 = 66%), a meta-regression analysis could not reveal plausible sources of heterogeneity. And ADE was associated with a shorter duration of total and initial antibiotic therapies and total length of hospital stay compared with non-ADE.

CONCLUSIONS: Our findings suggest that ADE seems to be significantly associated with better clinical outcomes compared with non-ADE. Caution is demanded when interpreting data of this study because of substantial between-study heterogeneity.

ABSTRACT

INTRODUCTION: To evaluate the degree to which socioeconomic differences in gestational diabetes mellitus (GDM) are accounted for by differences in maternal risk factors, to assess whether age-related risks of GDM differ across socioeconomic groups, and to identify priority populations for future interventions.

RESEARCH DESIGN AND METHODS: We performed a register-based study using data from the Finnish Medical Birth Register and Statistics Finland on the 474 166 women who gave birth in Finland from 2008 to 2015. We collected information on GDM based on the International Classification of Diseases 10th Revision codes O24.4 and O24.9. We used multivariable models to examine the association between socioeconomic status, maternal risk factors, and GDM. We further tested interaction on multiplicative and additive scales.

RESULTS: The incidence of GDM was 8.7% in 2008-2011 and 12.5% in 2012-2015. Lower socioeconomic levels than upper level employees were associated with an increased risk of GDM. Up to 64.0% of socioeconomic differences in GDM were attributed to body mass index and 5.5% to smoking. There was evidence for effect modification. Relative to women in the upper level category who were aged less than 19 years, GDM adjusted ORs (95% CIs) for women 35 years or older in upper level versus long-term unemployed groups were 3.28 (2.08-5.18) and 5.29 (3.35-8.35), respectively.

CONCLUSIONS: There is a paradox that socioeconomic advantage increases the incidence of GDM at the population level while reducing the incidence of GDM within the population. Nevertheless, socioeconomic differences in GDM persist and widen with increasing maternal age, even after accounting for maternal risk factors.

ABSTRACT

BACKGROUND: In achieving the WHO’s Universal Health Coverage and the Global Developmental Agenda: Sustainable Development Goal 3 and 9, the Ministry of Health launched a nationwide deployment of the lightwave health information management system (LHIMS) in the Central Region to facilitate health service delivery. This paper assessed the efficient use of the LHIMS among health professionals in the Central Region.

METHODS: A non-interventional descriptive cross-sectional study design was employed for this research. The study used stratified and simple random sampling for selecting 1126 study respondents from 10 health facilities that use the LHIMS. The respondents included prescribers, nurses, midwives and auxiliary staff. Descriptive statistics (weighted mean) was computed to determine the average weighted score for all the indicators under efficiency. Also, bivariate (χ²) and multivariate (ordinal logistic regression) analyses were conducted to test the study’s hypotheses.

RESULTS: Findings revealed that the LHIMS enhanced efficient health service delivery. From the bivariate analysis, external factors; sex, educational qualification, work experience, profession type and computer literacy were associated with the efficient use of the LHIMS. However, training offered prior to the use of the LHIMS, and the duration of training had no association. At the multivariate level, only work experience and computer literacy significantly influenced the efficient use of the LHIMS.

CONCLUSION: The implementation of LHIMS has the potential to significantly improve health service delivery. General computing skills should be offered to system users by the Ministry of Health to improve literacy in the use of computers. Active participation in the use of LHIMS by all relevant healthcare professionals should be encouraged.

ABSTRACT

OBJECTIVE: To estimate the effects of providing access to an alcohol intervention based on a smartphone.

DESIGN: Randomised controlled trial..

SETTING: Four higher education institutions in Switzerland.

PARTICIPANTS: 1770 students (≥18 years) who screened positive for unhealthy alcohol use (ie, a score on the alcohol use disorders identification test-consumption (AUDIT-C) of ≥4 for men and ≥3 for women) were randomly assigned by 1:1 allocation ratio in blocks of 10.

INTERVENTION: Providing access to a brief, smartphone based alcohol intervention.

OUTCOME MEASURES: The primary outcome studied was number of standard drinks per week at six months and the secondary outcome was number of heavy drinking days (past 30 days). Additional outcomes were maximum number of drinks consumed on one occasion, alcohol related consequences, and academic performance. Follow-up assessments occurred at months three, six, and 12. Data were analysed by intention to treat and by using generalised linear mixed models with random intercepts for the recruitment site and participants nested within the recruitment site, and with intervention (v control), time (three months v six months; 12 months v six months), and baseline outcome values as fixed effects.

RESULTS: Between 26 April 26 2021 and 30 May 2022, 1770 participants (intervention group (n=884); control group (n=886)) were included. Mean age was 22.4 years (standard deviation 3.07); 958 (54.1%) were women; and 1169 (66.0%) were undergraduate students, 533 (30.1%) were studying for a master’s degree, 43 (2.4%) were studying for a doctorate, and 25 (1.4%) were students of other higher education programme. The baseline mean number of standard drinks per week was 8.59 (standard deviation 8.18); the baseline number of heavy drinking days was 3.53 (4.02). Of 1770 participants, follow-up rates were 1706 (96.4%) at three months, 1697 (95.9%) at six months, and 1660 (93.8%) at 12 months. Of 884 students randomly assigned to the intervention group, 738 (83.5%) downloaded the smartphone application. The intervention had a significant overall effect on the number of standard drinks per week (incidence rate ratio 0.90 (95% confidence interval 0.85 to 0.96)), heavy drinking days (0.89 (0.83 to 0.96)), and the maximum number of drinks consumed on one occasion (0.96 (0.93 to 1.00), P=0.029), indicating significantly lower drinking outcomes in the intervention group than in the control group during the follow-up period. The intervention did not affect alcohol related consequences or academic performance.

CONCLUSIONS: Providing access to the smartphone application throughout the 12 month follow-up was effective at limiting the average drinking volume of university students who had self-reported unhealthy alcohol use at baseline.
