ABSTRACT

OBJECTIVE: The presence of Aedes albopictus, of high sanitary and social impact, was first reported in Valencia (Eastern Spain) in 2015. Innovative tools for its control include the use of the endosymbiotic bacterium Wolbachia pipientis. The release of mosquito males infected with the wPip strain, has proven very promising for large-scale Incompatible Insect Technique (IIT) applications. Before this strategy can be implemented in Valencia, it is important to know whether the natural local mosquito populations are Wolbachia-infected and, if so, identifying the infecting strains/supergroups, these being the objectives of the present work.

METHODS: Eggs were collected from the 19 districts of the València city between May and October 2019. A total of 50 lab-reared adult Ae. albopictus individuals were processed and analyzed for Wolbachia detection and molecular characterization. These actions took place within the framework of a collaboration established with the Department of Health and Consumer Affairs of the city council of Valencia. Fisher’s exact test was used to detect the statistical significance of the differences between groups.

RESULTS: Our study revealed that 94% of the analyzed samples were naturally infected with Wolbachia. Both wAlbA and wAlbB supergroups were identified, with most samples (72% of the infected ones) carrying co-infections.

CONCLUSIONS: These data provide the first characterization of the Wolbachia presence in natural populations of Ae. albopictus in the Mediterranean area of Spain. This information is relevant to evaluate the potential use of Wolbachia strains in order to achieve the suppression of the Asian tiger mosquito populations through massive release of artificially-infected males.

ABSTRACT

OBJECTIVE: The feminization of migration, the need to provide health care to an increasingly diverse population, seeking optimal health data led to considering this research. The objective was to determine the characteristics (socio-demographic profile, obstetric and gynecological record, and monitoring) of migrated pregnant women with a pregnancy process completed in 2019 in Catalonia compared to native women, in public centers (ASSIR-ICS).

METHODS: This descriptive study was based on computerized clinical records of women in the 28 centers dependent on the ICS. A descriptive analysis of the variables was carried out to compare the origin of the pregnant women. The Pearson Chi-Square test at 5% and the corrected standardized residual was used to compare the groups and an analysis of variance for the comparison of means also at 5%.

RESULTS: 36.315 women were analyzed and the resulting mean age was 31.1 years. The BMI at the beginning of pregnancy was 25.4 on average. Smoking habit was 18.1% among Spanish 17.3% among European. Sexist violence was 4% in Latin American women, being statistically higher than the rest. The risk of preeclampsia was 23.4% in sub-Saharan women. Gestational diabetes was diagnosed mainly among Pakistanis (18.5%). The prevalence of Sexually Transmitted Infections (STIs) was detected in Latin Americans (8.6%), Spanish (5.8%) and Europeans (4.5%). Sub-Saharan women performed insufficient ultrasound control (58.2%) and had the lowest percentage of visits with 49.5%. Pregnancy monitoring was insufficient in 79.9% of all rural pregnant women.

CONCLUSIONS: There are differences derived from the geographical origins of pregnant women that condition access to health services.

ABSTRACT

The low cardiovascular risk group according to SCORE in relation to the clinical and laboratory characteristics of patients is very heterogeneous, which leads to the presence of a residual risk of cardiovascular events. This category may include individuals with a family history of cardiovascular disease at a young age, with abdominal obesity (AO), endothelial dysfunction, and high levels of triglyceride-rich lipoproteins. In this regard, an active search is underway for new metabolic markers within the low cardiovascular risk group. The purpose of the study was to compare the nutrition, the adipose tissue distribution in low cardiovascular risk individuals, depending on the AO. Material and methods. The study included 86 healthy low risk (SCORE<1%) patients (mean age 42.6±2 years), who were divided into 2 groups: with AO [waist circumference (WC) >=94 cm in men and >=80 cm in women] – 44 patients (32% of men) and without AO – 42 patients (38% of men). The body composition was carried out using the bioimpedance analyzer. The distribution of ectopic fat deposits in the liver, pancreas and epicardial region was studied using ultrasound methods. A frequency questionnaire (Diet Risk Score) was used to assess nutrition. Results. In low risk patients with AO, signs of unhealthy diet are statistically significantly more common (in 52 in the main group vs 2% in the control group, p<0.01), ectopic deposition of adipose tissue in the liver (53 vs 9%, p<0.001), pancreas (56% in the main group, absent in the control group, p<0.001), epicardia l region (the epicardial fat thickness median is 4.24 mm in the main group vs 2.15 mm in the control group) compared with a control group. Conclusion. The low cardiovascular risk group is very heterogeneous. One of the markers of heterogeneity is central obesity – a marker of unhealthy diet, subclinical ectopic fat deposition and hypertriglyceridemia. Patients with AO of the low cardiovascular risk group require a more thorough examination with the obligatory determination of waist circumference, ultrasound assessment of the liver and pancreas parenchyma, and determination of the epicardial fat thickness. Using a short nutrition questionnaire allows you to quickly identify signs of unhealthy diet and discuss them with the patient.

ABSTRACT

Restoring the adaptive potential of an athlete is of paramount importance not only for the implementation of his training and competitive activities, but also for maintaining health. One of the leading place in complex recovery programs in sports is given to full-fledged optimal nutrition, which provides for meeting the body’s requirements not only in energy, macro- and micronutrients, but also in minor bioactive compounds. The use of anthocyanin-containing products is a promising strategy for the normalization of metabolic and immune disorders that develop as a result of intense physical and neuro-emotional stress not only in athletes, but also in other groups of people exposed to these factors, including military personnel undergoing training in conditions close to combat. This determines the relevance of this study. The aim of the research was to study the effect of an anthocyanin-enriched diet on hematological profile and cellular immunity in rats after intense physical activity. Material and methods. The experiment was carried out for 4 weeks on 4 groups of male Wistar rats with an initial body weight of ~300 g. The motor activity of the animals of the 1st (control) and 2nd groups was limited by the standard keeping animals in the vivarium, while physically active rats of the 3rd and 4th groups received additional physical activity – training on a treadmill. Before the end of the experiment, the animals of 3rd and 4th groups were given debilitating physical activity on a treadmill (until the rats refused to continue the exercise). Rats of all 4 groups received a standard semi-synthetic diet, water ad libitum. Animals in 2nd and 4th groups were additionally fed blueberry and blackcurrant extract (30% anthocyanins) as part of the diet at a daily dose of 15 mg anthocyanins/kg body weight. Hematological parameters were determined on a Coulter ACT TM 5 diff OV hematological analyzer. Expression of CD45R, CD3, CD4, CD8a, CD161 receptors on rat peripheral blood lymphocytes was determined by direct immunofluorescent staining of whole blood cells using a panel of monoclonal antibodies conjugated with fluorescent dyes: APC, FITC, PE. The measurements were carried out on an FC-500 flow cytometer. Results. Intense physical activity in rats of the 3rd group did not lead to a significant change in erythrocyte parameters compared with the control group. Enrichment of the diet with blueberry and black currant extract (the 2nd and the 4th groups) provided a significant (p<0.05) increase in blood content of hemoglobin (Hb) (150.7±0.9 and 154.4±2.0 vs 145.4±0.9 g/l in control), hematocrit (44.95±0.21 and 46.18±0.64 vs 43.78±0.32%) and the average content of Hb in erythrocytes (18.00±0.20 and 18.03±0.24 vs 17.35±0.24 pg). The absolute content of leukocytes and other cellular elements of the leukocyte formula, as well as leukocyte indices in rats of the experimental groups didn’t significantly differ from those of the control rats, which confirms the absence of an inflammatory process. Intense physical activity and anthocyanin enrichment of the diet didn’t have a significant effect on rat platelet parameters. Enrichment of the diet of rats of the 4th group with blueberry and black currant extract led to the activation of cellular immunity, as evidenced by a significant (p<0.01) increase in the percentage (from the total content of T-lymphocytes) of T-helpers (70.13 ±1.34 vs 63.75±0.99%) and a decrease in the relative content of cytotoxic T-lymphocytes (28.65±1.38 vs 34.71±0.95%) in comparison with those in rats of the 3rd group and at the level of the trend (р<0.1) – from the 1st group indexes (66.87±1.20 and 31.87±1.26%, accordingly). Intense physical activity led to a decrease in immunoregulatory index in rats of the 3rd group (1.86±0.07) compared with the control (2.13±0.12) (p<0.1), and in animals of the 4th group this indicator was significantly higher (2.50±0.14, p<0.05). In animals of the 3rd group a statistically significant (p<0.05) decrease in the relative content of NK cells in peripheral blood was found compared to the control. Enrichment of the diet of physically active rats with blueberry and black currant extract led to a significant (p<0.05) increase in the percentage of NK cells compared to this indicator in rats of the 3rd group (4.87±0.75 vs 2.08±0.18%) and had no significant difference with the indicator in rats of the control group (4.32±0.98%). Conclusion. The enrichment of the rats’ diet with blueberry and blackcurrant extract containing a daily dose of 15 mg of anthocyanins per kg of body weight provides an increase in blood Hb content, hematocrit and the average content Hb in erythrocytes. It has been established that intense physical activity induces the cellular immunity suppression. The activating effect of anthocyanins on adaptive cellular immunity and NK cells, which are lymphocytes of innate immunity, was revealed. The data obtained indicate the effectiveness of the use of bioactive compounds (anthocyanins) to increase the adaptive potential of the organism.

ABSTRACT

Plug-in fragrance diffusers are one of myriad volatile organic compound-containing consumer products that are commonly found in homes. The perturbing effects of using a commercial diffuser indoors were evaluated using a study group of 60 homes in Ashford, UK. Air samples were taken over 3 day periods with the diffuser switched on and in a parallel set of control homes where it was off. At least four measurements were taken in each home using vacuum-release into 6 L silica-coated canisters and with >40 VOCs quantified using gas chromatography with FID and MS (GC-FID-QMS). Occupants self-reported their use of other VOC-containing products. The variability between homes was very high with the 72 hour sum of all measured VOCs ranging between 30 and >5000 μg m^-3, dominated by n/i-butane, propane, and ethanol. For those homes in the lowest quartile of air exchange rate (identified using CO₂ and TVOC sensors as proxies) the use of a diffuser led to a statistically significant increase (p-value < 0.02) in the summed concentration of detectable fragrance VOCs and some individual species, e.g. alpha pinene rising from a median of 9 μg m^-3 to 15 μg m^-3 (p-value < 0.02). The observed increments were broadly in line with model-calculated estimates based on fragrance weight loss, room sizes and air exchange rates.

ABSTRACT

OBJECTIVE: The aim: To find the risk factors of microalbuminuria and estimated Glomerular Filtration Rate (eGFR) in patients with type 1 diabetes mellitus.

PATIENTS AND METHODS: Materials and methods: One hundred ten patients of type 1 diabetes mellitus in this cross-sectional study at diabetic and endocrinology center in Al-Najaf during the period from September 2021 to March 2022. All patients were asked about sociodemographic characteristics (age, gender, smoking, duration of DM type1, family history of DM type1), measured (body mass index BMI, blood pressure) and laboratory investigations done to all patients (G.U.E, s. creatinine, lipid profile, HBA1C, calculated estimated Glomerular Filtration Rate (eGFR) and Spot Urine Albumin-Creatinine Ratio (ACR).

RESULTS: Results: Out of 110 patients, 62 male and 48 female, the mean age was (22±12). The patients with microalbuminuria (ACR ≥ 30 mg/g) show statistically significant with increase HBA1C, duration of DM type 1, total cholesterol (T.C), low density lipoprotein (LDL), triglycerides (TG) and family history of DM type 1, while there were not statistically significant with age, gender, smoking, BMI, eGFR, high density lipoprotein (HDL) and hypertension. Patients with eGFR<90mL/min/1.73m2 show statistically significant with increase HBA1C, duration of DM type1, LDL, TG, T.C, while significantly decrease in HDL and there were not statistically significant with age, gender, smoking, family history of DM type 1, BMI and hypertension.

CONCLUSION: Conclusions: The degree of glycemic control, duration of type1 (DM) and dyslipidemia were associated with increased microalbuminuria and reduced eGFR (nephropathy). Family history of DM type1 was risk factor for microalbuminuria.

ABSTRACT

OBJECTIVE: The aim: To evaluate the effectiveness of the use of the Deprilium® complex for the relief of subclinical symptoms of depression in patients with NCD.

PATIENTS AND METHODS: Materials and methods: There were 140 patients involved in the study. To assess the subclinical symptoms, the Hamilton Depression Rating Scale (HAM-D) was used. In order to obtain additional information about the patient’s condition, the Somatic Symptom Scale SSS-8 and the Quality of Life Scale (QOLS) were used. Patients were randomized by block randomization to an intervention group, which took Deprilium® complex, and a control group, which took placebo.

RESULTS: Results: After 60 days a statistically significant difference was observed in all clinical indicators between the intervention group and the control group. The median value of the HAM-D scale differed between the groups by 6 points, significantly (p <0.000) lower results were observed in the intervention group, which participants were taking the Deprilium® complex. When comparing the indicators of the intervention group on the 1st and on the 60th day of the study, statistically significant changes (p <0.000) were observed in all three indicators.

CONCLUSION: Conclusions: The received results confirm the available evidence for the properties of SAMe in depression and complement them with evidence of the ef-fectiveness of the Deprilium® complex that contains SAMe and L-methylfolate with methylcobalamin, which together produce pharmacological and clinical synergy to reduce the severity of subclinical depressive manifestations in patients with NCD. Further studies of the effectiveness of the use of the Deprilium® complex in patients with NCD are required.

ABSTRACT

OBJECTIVE: The aim: To determine the effectiveness of application of special therapeutic physical exercises to improve the indicators of body weight, anthropometric parameters and quality of life of obese women in the conditions of quarantine restrictions.

PATIENTS AND METHODS: Materials and methods: We examined 10 women aged 37 ± 5 years with obesity of various degrees, which was determined by the body mass index (BMI, kg/m2). All women for two months were involved in specially designed therapeutic exercises in the remote mode. Evaluation of the effectiveness of therapeu¬tic exercises use was performed using the survey method to determine the quality of life of obese women according to a short version of the questionnaire “The world health organization quality of life (WHOQOL-BREF)”; anthropometric measurements of body parts sizes; bioimpedance analysis of body weight composition; statistical methods of data processing.

RESULTS: Results: The effect of therapeutic gymnastics according to the proposed programme on the component composition of body weight of obese women was proved, which indicates a decrease in total body weight, reduction of body fat, increase in total body water and muscle component of body weight. It is shown that under the influence of corrective physical exercises the proportions of the body of women changed, as evidenced by the dynamics of the circumferences of all measured parts of the body of obese women. The improvement of women’s quality of life in all indicators was identified.

CONCLUSION: Conclusions: The use of special complexes of physical exercises, aimed at correction of the body weight of obese women,showed its significant effectiveness and led to the expected result.
