Influence of the host sex, size, and season on Ergasilus lizae infestation of Thicklip Grey Mullet (Chelon labrosus, L., 1758) in Beymelek Lagoon Lake (Antalya, Türkiye)

The aim of the study was investigation of the changes in infestation levels of Ergasilus lizae on economically important fish species, thicklip grey mullet (Chelon labrossus) from Beymelek Lagoon Lake located on the western Mediterranean coast (Antalya, Türkiye). In this context, the infestation levels of E. lizae with respect to fish sexes, fish sizes and season were evaluated statistically. The research was conducted seasonally between May 2008 to April 2009, and the gills which belong to 103 fish samples were examined. The overall infection prevalence and mean intensity values were 60.2% and 15.95, respectively. The prevalence and mean intensity of E. lizae for thicklip grey mullet male and sexually unidentified fish samples were higher than that for females. Prevalence and mean intensity were determined the highest in size class I with 69.6% and 26.3, and almost the same values in size groups II and III. E. lizae on host fish were observed in every season. The highest prevalence and mean intensity of E. lizae was recorded in spring with 100%, 24.88. The lowest prevalence of E. lizae was recorded in summer at 12% and the lowest mean intensity of E. lizae was in the summer and the winter with 9, 8.67 respectively. The infestation level of E. lizae was statistically significant with host sex and season, but there was no effect on the fish size groups.

Retrospective Evaluation of Dental and Gingival Health in 150 Dogs

The aim of this study was to calculate the prevalence of gingivitis, calculus, and traumatic dentoalveolar injury as a result of dental and gingival examinations of 150 dogs brought to Burdur Mehmet Akif Ersoy University Animal Hospital due to various health problems. In this study, dogs were examined by inspection without anaesthesia or invasive techniques. As a result of the examination, calculus (87.2%), gingivitis (60.7%) and traumatic dentoalveolar injuries (51.3%) were found in the majority of patients at rates higher than the reported prevalence values. It was emphasised that if existing diseases are not treated, the general health of the patient may be adversely and irreversibly affected.

Improved Assessment of Schistosoma Community Infection Through Data Resampling Method.

The conventional diagnostic for Schistosoma mansoni infection is stool microscopy with the Kato-Katz (KK) technique to detect eggs. Its outcomes are highly variable on a day-to-day basis and may lead to biased estimates of community infection used to inform public health programs. Our goal is to develop a resampling method that leverages data from a large-scale randomized trial to accurately predict community infection. We developed a resampling method that provides unbiased community estimates of prevalence, intensity and other statistics for S mansoni infection when a community survey is conducted using KK stool microscopy with a single sample per host. It leverages a large-scale data set, collected in the Schistosomiasis Consortium for Operational Research and Evaluation (SCORE) project, and allows linking single-stool specimen community screening to its putative multiday "true statistics." SCORE data analysis reveals the limited sensitivity of KK stool microscopy and systematic bias of single-day community testing versus multiday testing; for prevalence estimate, it can fall up to 50% below the true value. The proposed SCORE cluster method reduces systematic bias and brings the estimated prevalence values within 5%-10% of the true value. This holds for a broad swath of transmission settings, including SCORE communities, and other data sets. Our SCORE cluster method can markedly improve the S mansoni prevalence estimate in settings using stool microscopy.

Latent Infestation of Potato Tubers with Soft Rot and Ring Rot Pathogens under Changing Weather Conditions in Ukraine

Potato is one of the most important food crops in the world. Cultivation of potatoes is an important segment of the agriculture and economy as a whole in Ukraine. Bacterial diseases such as ring rot caused by Clavibacter sepedonicus, as well as soft rot and blackleg caused by Pectobacterium atrosepticum evoke tremendous losses of the potato crop. Stored seed tubers are the main source of accumulating pathogens in latent form. In addition, potato crop yield and quality are significantly affected by weather conditions. Along with affecting potatoes directly, meteorological factors such as air temperature and humidity can also impact tuber infestation with bacterial pathogens. The aim of the study was to monitor the prevalence of bacterial ring rot pathogen C. sepedonicus and soft rot pathogen P. atrosepticum in potato tubers on the territory of Ukraine in 2020 and 2021 years and assess its association with different weather conditions. Methods. Potato seed lots from newly harvested crops in eight regions of Ukraine (Odesa, Kyiv, Donetsk, Kherson, Cherkasy, Mykolaiv, Dnipropetrovsk, and Zhytomyr regions) without visual symptoms of diseases were used for the experiments. The detection of C. sepedonicus and P. atrosepticum was conducted by the immunochemical method DAS ELISA. Basal meteorological data (the sum of precipitation (mm/month) and average air temperature (°C) were obtained from the local meteorological stations. The amplitude of air temperature and the sum of precipitation during potato planting, growing, and harvesting seasons, as well as Sielianinov’s hydrothermal coefficient (K) were additionally calculated. The Spearman correlation coefficient was used for the analysis of the correlation between pathogen prevalence and weather parameters. Results. Both ring rot pathogen C. sepedonicus and soft rot pathogen P. atrosepticum were detected in potato lots from all surveyed regions, but the prevalence of latent infestation varied between 2020 and 2021. In 2020, the highest soft rot pathogen prevalence values were registered for Mykolaiv, Kyiv, and Cherkasy regions (21.7, 10.5, and 10% respectively), where high rainfall levels in May and June were observed. In 2021, potato planting, growing, and harvesting seasons were marked by significantly higher precipitation levels, as compared to 2020, in all regions. Average occurrence values for P. atrosepticum in potato lots were 1.7 times higher than that in 2020. The highest prevalence (40%) was observed in the Donetsk region with extremely high air humidity during the potato growing period. Strong positive correlation (r = 0.721) was found between soft rot pathogen prevalence and K coefficients during the potato growing season, as well as between P. atrosepticum prevalence and the sum of precipitation during planting and early growing seasons. Prevalence of ring rot pathogen didn’t differ significantly in 2020 and 2021. The highest C. sepedonicus prevalence was observed in 2020 in the Kyiv region (18.9%), and in 2021 — in the Donetsk region (20%). A moderate positive correlation (r = 0.591) was found between pathogen prevalence and air temperature during planting and early growing season. Conclusions. Weather factors such as air temperature and humidity over the planting and early growing potato season can influence progeny tuber infestation with P. atrosepticum and C. sepedonicus. Knowledge of the effect of the changing weather conditions on the susceptibility of potato varieties with different genetic features to infestation with soft rot and ring rot pathogens warrants future investigation since it is crucially important for developing measures for disease control by potato producers.

A study on longitudinal relationship between ultrafine dust and the prevalence of depression

BackgroundRecently, the fine dust problem caused by rapid industrialization and science and technological development has emerged as a severe social issue worldwide. This also increases the interest in its effect on human life. In particular, there is a growing concern about the harm of fine dust in Korea.MethodsThis study is based on the PM 2.5 data from 2017 to 2021 provided by Air Korea to estimate changes in ultrafine dust. In addition, the data from the Community Health Survey provided by the Korea Centers for Disease Control and Prevention (KCDC) from 2017 to 2021 were used to examine the effect between the change in ultra-fine dust and the prevalence of depression. A total of 229 local governments were included in the analysis. The Latent Growth Modeling was carried out to estimate the change in ultra-fine dust and the prevalence of depressions and verify the relationship between ultra-fine dust and the prevalence of depression.ResultsThe analysis result revealed that the ultra-fine dust concentration continued to decrease from 2017 to 2021. However, the depression prevalence increased from an average of 2.60% in 2017 to an average of 3.12% in 2021, suggesting the need for adequate and sufficient welfare policies for depression treatment. As a result of estimating the initial value and change rate of ultra-fine dust and depression prevalence, the higher the initial value of ultra-fine dust, the greater the decrease in ultra-fine dust. In terms of depression, the lower the initial value of the prevalence of depression, the larger the increase in depression prevalence.ConclusionsThis study is significant in that it revealed the strong association of the longitudinal relationship between ultra-fine dust and depression, one of the biggest issues in Korea, by utilizing large-scale longitudinal data.

Physical Inactivity Prevalence in the Islamic World: An Updated Analysis of 47 Countries.

Physical inactivity prevalence estimates for youth and adults have been published on a global scale and for various geographical and geopolitical permutations. Only one such study has presented estimates for adults in Muslim countries, and it is nearly 10years old. I conducted an update of this study by incorporating newer data, refining methods, and including youth estimates. I identified 47 Muslim countries with physical inactivity data for youth, adults, or both. Data were extracted by country primarily from global estimates reported by Guthold etal in 2018 and 2020 and from World Health Organization surveillance data repositories. Weighted prevalence calculations for total prevalence and by sex, ethnicity (Arab vs non-Arab), and country income group accounted for country population, study sample size, and a country's proportion of Muslims. Z tests and chi-square tests, and follow-up odds ratios and percentage deviations, respectively, were used to determine differences by sex, ethnicity, and country income group. Overall physical inactivity prevalence was 84.2% (youth) and 29.6% (adults). Gaps favoring males over females were observed for youth (5.6% lower prevalence) and adults (9.6% lower prevalence). Gaps favoring non-Arabs over Arabs were observed for youth (3.9% lower) and adults (3.8% lower). No pattern emerged for country income group for youth; however, prevalence for adults trended upward across income groups from low (22.7%) to high (62.0%). Gaps by sex and ethnicity have narrowed since the original report and prevalence values are somewhat higher than current global estimates.

Identification, prevalence and intensity of ectoparasite in sand lobster (Panulirus homarus) cultivated in floating cages (floating net cage) and bottom cage (bottom cage)

Lobster (Panulirus homarus) is one of the marine fishery commodities that is gaining popularity and has been widely cultivated in Indonesia. This is because lobster has great business prospects and is one of the important commodities and has high economic value. Lobster cultivation can now be done in various systems including floating net cages, bottom cages and ponds. The problem that is often faced by cultivators is the emergence of diseases in the lobster cultivation cycle caused by an unbalanced interaction between lobster conditions, the environment, and pathogens. This is one of the main problems in lobster cultivation that can interfere with the survival of lobsters and can also cause death. Research on ectoparasite infection in Sand Lobster (Panulirus homarus) cultured in floating net cages and bottom cages aims to identify the types of ectoparasites and calculate the prevalence and intensity of ectoparasites infecting sand lobster (Panulirus homarus). The method used in this study is a survey method. The sampling method was carried out by random sampling method and the method of analysis and presentation of data using descriptive methods. The main parameters observed in this study were the type of ectoparasites, prevalence and intensity values of sand lobster (Panulirus homarus) infected with ectoparasites, while the supporting parameter was lobster size. The ectoparasite found to infest the sand lobster (Panulirus homarus) was Octolamis angulata. The highest prevalence value was obtained in cultivation using floating net cages of 53,3% which belonged to the Frequently category (commonly) and the highest intensity value was obtained in cultivation using floating net cages of 30,1 which belonged to the Medium category (currently). It is necessary to conduct further studies on Octolasmis species based on the DNA chain arrangement and description of tissue damage due to Octolasmis infestation

Psychological distress in nursing students: relationship with screen time, diet and physical activity.

to determine the prevalence of anxiety and depression symptoms, as well as their association with screen time, diet and physical activity, in a cohort comprised by nursing students. a descriptive and cross-sectional study conducted with a sample of 648Nursing students. The instruments used were the Hospital Anxiety and Depression Scale, the short version of the International Physical Activity Questionnaire and the Spanish Healthy Eating Index (Índice de Alimentación Saludable Español, IASE). Different multiple linear regression models were performed to analyze the association between anxiety/depression symptoms and screen time, diet and physical activity. the prevalence values for anxiety and depression symptoms were 24.1% and 3.7%, respectively. Prolonged screen times (>6 hours a day), low levels of physical activity and inadequate diet were independently and significantly associated with deeper psychological symptoms. Nursing students' mental health might benefit from the implementation of initiatives promoting healthy lifestyles.

Prevalence of tuberculosis, COVID-19, chronic conditions and vulnerabilities among migrants and refugees: an electronic survey.

to analyze the prevalence of tuberculosis, coronavirus, chronic conditions and vulnerabilities among migrants and refugees in Brazil. this is a cross-sectional study of the electronic survey type conducted with international migrants during the COVID-19 pandemic. Descriptive statistics was applied for the analysis, with calculation of position and dispersion measures. Regarding the categorical variables, relative and absolute frequencies were estimated. the study participants were 553 migrants and refugees, verifying 3.07%, 7.2% and 27.3% prevalence of tuberculosis, COVID-19 and chronic conditions, respectively. Among the vulnerabilities, 32% reported unemployment, 37.6% moved to Brazil as a result of the social situation in their countries and 33.6% were living as refugees or sheltered people. tuberculosis, chronic diseases and COVID-19 presented higher prevalence values in migrants and refugees than in the general population. As this is a population group that still has significant difficulty accessing health services and social protection systems, based on diverse evidence, the study will subsidize public policies, Nursing care and the incorporation of new routines in the service.

Diagnostic Performance of the Measurement of Skinfold Thickness for Abdominal and Overall Obesity in the Peruvian Population: A 5-Year Cohort Analysis

The escalating prevalence of overall and abdominal obesity, particularly affecting Latin America, underscores the urgent need for accessible and cost-effective predictive methods to address the growing disease burden. This study assessed skinfold thicknesses’ predictive capacity for overall and abdominal obesity in Peruvian adults aged 30 or older over 5 years. Data from the PERU MIGRANT 5-year cohort study were analyzed, defining obesity using BMI and waist circumference. Receiver operating characteristic curves and area under the curve (AUC) with 95% confidence intervals (CI) were calculated. Adults aged ≥ 30 (n = 988) completed the study at baseline, with 47% male. A total of 682 participants were included for overall and abdominal obesity analysis. The 5-year prevalence values for overall and abdominal obesity were 26.7% and 26.6%, respectively. Subscapular skinfold (SS) best predicted overall obesity in men (AUC = 0.81, 95% CI: 0.75–0.88) and women (AUC = 0.77, 95% CI: 0.67–0.88). Regarding abdominal obesity, SS exhibited the highest AUC in men (AUC = 0.83, 95% CI: 0.77–0.89), while SS and the sum of trunk skinfolds showed the highest AUC in women. In secondary analysis excluding participants with type-2 diabetes mellitus (DM2) at baseline, SS significantly predicted DM2 development in men (AUC = 0.70, 95% CI: 0.58–0.83) and bicipital skinfold (BS) did in women (AUC = 0.73, 95% CI: 0.62–0.84). The findings highlight SS significance as an indicator of overall and abdominal obesity in both sexes among Peruvian adults. Additionally, SS, and BS offer robust predictive indicators for DM2.

Socioeconomic disparities in attention deficit hyperactivity disorder (ADHD) in Sweden: An intersectional ecological niches analysis of individual heterogeneity and discriminatory accuracy (IEN-AIHDA).

We aimed (i) to gain a better understanding of the demographic and socioeconomical distribution of ADHD risk in Sweden; and (ii) to contribute to the critical discussion on medicalization, i.e., the tendency to define and treat behavioural and social problems as medical entities. For this purpose, we analysed the risk of suffering from ADHD in the whole Swedish population aged between 5 and 60 years, across 96 different strata defined by combining categories of gender, age, income, and country of birth. The stratified analysis evidenced considerable risk heterogeneity, with prevalence values ranging from 0.03% in high income immigrant women aged 50-59, to 6.18% in middle income immigrant boys aged 10-14. Our study questions the established idea that behavioural difficulties conceptualized as ADHD should be primarily perceived as a neurological abnormality. Rather, our findings suggest that there is a strong sociological component behind how some individuals become impaired and subject to medicalization.

Gastrointestinal Nematodes and Protozoa in Small and Large Ruminants from Rural Agro-Climatic Regions of Northern India

Gastrointestinal nematode parasites and gastrointestinal protozoan parasites are considered detrimental to the livestock population and manifest production-limiting effects. Small and large ruminants (cattle, buffalo, goats, and sheep) are important components of the rural economy of northern India. However, the epidemiology of gastrointestinal parasites in this agro-climatic region has not been studied extensively. In this study, the prevalence of gastrointestinal parasites was determined in 163 animals, including cattle (n = 86), buffalo (n = 11), goats (n = 48), and sheep (n = 18) from 26 sampling sites by copro-parasitological analysis. The prevalence values of 94.47% and 66.87% were recorded for the nematodes and protozoa, respectively. The group-wise prevalence of gastrointestinal nematode parasites was 95.3%, 90.9%, 93.7%, and 94.4% in cattle, buffalo, goats, and sheep, respectively, whereas for gastrointestinal protozoan parasites, the respective values were 70.9%, 54.5%, 60.4%, and 72.2%. Copromicroscopy revealed ten genera of nematodes—Ascaris, Capillaria, Cooperia, Haemonchus, Nematodirus, Oesophagostomum, Ostertagia, Strongyloides, Trichostrongylus, Trichuris, and one protozoan genus—Eimeria. The prevalence of Trichostrongylus spp. was highest in buffaloes, whereas in cattle, Ascaris spp. were predominant. In both goats and sheep, Haemonchus contortus was found to be predominant. The highest prevalence of gastrointestinal parasites was recorded in the rainy season. These findings indicate the prevalence of gastrointestinal parasites in the ruminant population in this region and necessitate the implementation of preventive and control strategies for effective animal health management.

Association of Complete Blood Cell Count-Derived Inflammatory Biomarkers with Psoriasis and Mortality.

Psoriasis is a persistent inflammatory disorder that affects 3% of the population and is associated with cardiovascular diseases. Therefore, this study aimed to investigate the correlations between complete blood cell count (CBC)-derived inflammatory biomarkers, psoriasis prevalence, and all-cause mortality. Data were obtained from the National Health and Nutrition Examination Survey (NHANES) spanning 2003-2006 and 2009-2014. Mortality data up to December 31, 2019 were obtained using the National Death Index. The following CBC-derived inflammatory biomarkers were examined: neutrophil/lymphocyte ratio (NLR), neutrophil/(white blood cells - neutrophils) ratio (dNLR), monocyte count/lymphocyte ratio (MLR), (neutrophil + monocyte)/lymphocyte ratio (NMLR), platelet/lymphocyte ratio (PLR), and systemic inflammatory response index (SIRI). Weighted logistic and Cox regression analyses were used to calculate odds ratios, hazard ratios, and the corresponding 95% confidence intervals. Additionally, the prognostic value of the inflammatory indicators was assessed and ranked using the random survival forest approach. In total, data from 21,431 participants with average age of 45.02 ± 0.27 years (49.51% male) were included in the study, among which 600 participants were positive for psoriasis (prevalence rate, 2.80%). Additionally, 79 all-cause deaths were recorded during a median follow-up period of 8.83 (6.67-11.00) years. Moreover, NLR, dNLR, NMLR, PLR, and SIRI were positively associated with the prevalence of psoriasis. Furthermore, MLR, NMLR, and SIRI were positively correlated with all-cause mortality in patients with psoriasis, with NMLR being the most valuable predictor of all-cause mortality. CBC-derived inflammatory biomarkers were associated with psoriasis prevalence, NMLR, SIRI, and MLR values were associated with all-cause mortality in patients with psoriasis. Overall, assessment of these CBC-derived indicators may serve as a simple method for screening high-risk individuals among patients with psoriasis.

The prevalence of coronary microvascular dysfunction (CMD) in heart failure with preserved ejection fraction (HFpEF): a systematic review and meta-analysis.

To date, studies on the prevalence of coronary microvascular dysfunction (CMD) in heart failure with preserved ejection fraction (HFpEF) have not been summarized and analyzed as a whole. We conducted this systematic review and meta-analysis to assess the prevalence of CMD in patients with HFpEF. The PubMed, Cochrane, and Embase databases were searched from dates of inception until May 1, 2023. The primary outcome was the prevalence of CMD in patients with HFpEF, and values of CMD prevalence were pooled using a random-effects model. In total, 10 studies involving 1267 patients, including 822 with HFpEF and 445 without HFpEF, were included. The pooled prevalence of CMD in patients with HFpEF was 71% (95% CI, 0.63-0.79). In the subgroup analysis, the prevalence of CMD was 79% (95% CI, 0.71-0.87) by invasive measurement and 66% (95% CI, 0.54-0.77) by noninvasive measurement and 67% (95% CI, 0.52-0.82) with CFR < 2.0 and 75.0% (95% CI, 0.71-0.79) with CFR < 2.5. The prevalence of endothelium-independent CMD and endothelium-dependent CMD was 62% (95% CI, 0.53-0.72) and 50% (95% CI, 0.19-0.81), respectively. The prevalence of CMD was 74% (95% CI = 0.69-0.79) and 66% (95% CI = 0.41-0.90) in prospective and retrospective studies, respectively. Compared with the control group, patients with HFpEF had a significantly lower CFR (MD = - 1.28, 95% CI = - 1.82 to - 0.74, P < 0.01) and a higher prevalence of CMD (RR = 2.21, 95% CI = 1.52 to 3.20, P < 0.01). Qualitative analysis demonstrated that CMD might be associated with poor clinical outcomes in patients with HFpEF. In conclusion, this is the first systematic review and meta-analysis of all studies reporting the prevalence of CMD in patients with HFpEF. Our study demonstrates that CMD is common in patients with HFpEF and might be associated with poor clinical outcomes in these patients. Clinicians should attach importance to CMD in the diagnosis and treatment of HFpEF. The number of studies in this field is relatively small. Therefore, more high-quality studies are needed to explore the diagnostic and prognostic value of CMD and the potential role of CMD as a therapeutic target in patients with HFpEF.

Foodborne hazards in food in Burkina Faso, 1990–2019: a systematic review and meta-analysis

BackgroundFoodborne diseases impose substantial public health burden and jeopardize socio-economic development worldwide. While accurate information on foodborne hazards is needed for informed decision in food safety interventions, such information is scarce in developing countries such as Burkina Faso. We conducted a systematic review and meta-analysis of studies reporting foodborne hazards in foods in Burkina Faso to describe the present knowledge of the situation.MethodsPreferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was used to conduct this review. Abstracts were searched in PubMed and CAB direct between 1 January 1990 to 30 September 2019. We used random-effects models to estimate pooled prevalence and I2 values to measure heterogeneity between studies.Results188 articles were identified, of which 14 are included in this review: 12 were on bacterial hazards (Salmonella, Campylobacter, Staphylococcus, E. coli, Shigella), three on fungal hazards and one on parasitic hazards (Toxoplasma gondii). The overall pooled prevalence of Salmonella spp. was 13% (95% CI: 8–21), the highest in lettuce: 50% (95% CI: 30–70) and the lowest in milk: 1.2% (95% CI: 0–5), demonstrating substantial variation among the studies (I2 = 85, 95% CI: 79–90%, p &amp;lt; 0.01). Campylobacter spp. was reported in chicken carcass, with 50% of the samples being positive. The overall pooled microbial load of Staphylococcus in the studied food samples was 3.2 log (95% CI: 2.8–3.6) CFU per g or ml of food, the highest in poultry samples: 4.5 log (95% CI: 2.8–6.2) CFU per g or ml of food. The overall pooled prevalence of Escherichia coli (E. coli) was 40% (95% CI: 29–51), the highest in beef intestines: 62% (95% CI: 22–91) and the lowest in dairy products: 31% (95% CI: 17–50), showing substantial variation across the studies (I2 = 86, 95% CI: 80–90%, p &amp;lt; 0.01).ConclusionOur results showed widespread contamination of foods with foodborne hazards across various food value chains indicating poor hygienic handling of foods, raising consumers’ health risk due to foodborne illnesses from the foods. We recommend promotion of awareness creation in food safety and improved monitoring of hazards in food.

The relationship between ABO blood group and blood transfusion in upper gastrointestinal bleeding

Introduction: ABO blood group (BG) antigens found in many cells and tissues, especially in erythrocytes, have been associated with many diseases including cardiovascular diseases, infections, and malignancies. The association of ABO BG with duodenal and gastric ulcers and upper gastrointestinal bleeding (UGB) has been investigated in few studies and the information on this subject is limited. The primary objective of our study is to examine whether there is an association between ABO BG and UGB, and the secondary objective is to examine whether there is an association between ABO BG and UGB in patients who received blood transfusions after bleeding. Methods: The prevalence values of A, B, AB, 0 BG and Rh antigens, endoscopic procedure, and blood transfusion information of patients who were diagnosed with UGB by endoscopic examination and hospitalized were recorded. Healthy individuals without UGB in the same period were included as the control group (CG). Those who had UGB by endoscopic examination constituted the study group (SG) while those who received at least 2 units of blood transfusion formed the transfusion group (TG). Results: SG consisted of 423 patients, TG included 383 patients, and CG had 1650 individuals. While the risk of bleeding was higher in SG patients with BG 0 (OR 1.33 1.07-1.66 P=0.009), the bleeding risk was lower in SG patients with BG B (OR 0.77 0.63-0.95 P=0.014). In addition, while the risk of bleeding was higher in TG patients with BG 0 (OR 1.35 1.08-1.70 P=0.009), the bleeding risk was lower in TG patients with BG B (OR 0.55 0.38-0.79 P=0.001). There was no statistically significant difference in SG, and TG in other BG A and AB and no significant difference in Rh. Conclusion: While UGB is more common in individuals with BG 0, it is less common in individuals with BG B. The risk of need for blood transfusion during the follow-up period of these patients in the ward is higher in patients with BG 0 but lower in patients with BG B. Keywords: Blood group, bleeding, transfusion

A Temporal Analysis of Parasitic Infections in Indian Mackerel, Rastrelliger kanagurta (Cuvier, 1817) along the Western Coast of Karwar Bay, Karnataka: Employing a Monthly Assessment with histopathology

The study showed the morphological identification, prevalence, and severity of the infestation of parasites in R. kanagurta from the Karwar coast, month-wise from January to December 2022. The current study investigated and found Norileca indica and Nerocila phaiopleura Trichodina spp., and developmental stages of helminths in R. kanagurta during this period. A total of 755 fish were examined, and the monthly prevalence was estimated. Statistical analysis revealed that the P value is lesser than the significant value (P&lt;0.05, df=3), which indicates there are significant differences in PFI (% prevalence) values of each group/among the parasites (N. indica, N. phaiopleura, Helmenth, Trichodina spp.) and also there is a significant difference of prevalence in monthly (P&lt;0.05,df=11). Weather changes like temperature, salinity, flood water, pollutants, ballast water, and sudden rainfall all play a key role in the infestation of parasites in the selected fish. Availability of the host (R. kanagurta), breeding season, and ban period (west coast) were also important factors causing the parasitic infestation. In conclusion, Norileca indica and Nerocila phaiopleura, Trichodina spp., Isopods, and developmental stages of helminth parasites were causing histological alterations in the infected tissues.

The burden of scoliosis: a nationwide database study on demographics, incidence, and surgical rates.

Scoliosis is characterized as a three-dimensional deformity of the spine, affected by variety of factors, including biological, mechanical, hormonal, and genetics. Our study's primary objective was to delineate the demographics, incidence, and prevalence of scoliosis from a nationwide perspective, analyze the surgical intervention rates, with the aim of offering more insightful guidance to orthopedic physicians. This nationwide cohort study was conducted from digital database for healthcare information management. Relevant population data, for children under 18 years old, was extracted from the official government census within the period of January 2015 to December 2022. Utilizing diagnostic code of M41 [Scoliosis] was used to define the patient pool from ICD-10. Demographic variables, type of operations (posterior only, anterior only, or combined), and complications were documented. Incidence and prevalence values were calculated using population figures and case numbers. There were 276,521 patients with an average incidence of 129 per 100,000. Frequency of females was 1.45 times greater than that of males (p < 0.001). A total of 10,417 surgeries were performed in 10,311 patients during the inspection period (3.8% of all cases). Posterior fusion was by far the most common surgical approach (n = 10.111; 97%) followed by anterior fusion (n = 200; 1,9%). Our findings reveal a significant increase in the average incidence of scoliosis diagnosis, rising from 107 per 100,000 individuals in 2015 to 161 per 100,000 in 2022. Scoliosis now impacts an estimated 1.2% of children and adolescents in Turkey. The risk is 1.45 times higher in females than in males.

Entomological Survey and Leishmania (Leishmania) mexicana Prevalence in Sand Fly Species during an Outbreak of Cutaneous Leishmaniasis in Quintana Roo State, Mexico.

(1) Background: Localized cutaneous leishmaniasis is a neglected vector-borne disease that has become a serious public health problem in the Yucatan Peninsula. Although more than 60% of cases originate from the state of Quintana Roo, it is one of the least explored areas in terms of incriminating vectors of the Leishmania parasite. Additionally, cases of leishmaniasis have increased substantially in that region in recent years. For this reason, we explored and provided primary evidence of Leishmania DNA in sand fly species from four localities during outbreaks of leishmaniasis in Quintana Roo. We also contributed information on the regional genetic diversity of Leishmania parasites. (2) Methods: Sand flies were collected during several periods from November 2022 to April 2023 using Mosquito Light Circle and Shannon traps, as well as an active entomological search in refuges. For Leishmania detection, we amplified a fragment of 300-350 bp of the internal transcribed spacer subunit 1 (ITS-1). (3) Results: Of the 242 females collected, we detected Leishmania DNA in 25 specimens represented by Bichromomyia olmeca (1), Psathyromyia shannoni (17), Lutzomyia cruciata (4), Psathyromyia undulata (2), and Dampfomyia deleoni (1). The detection of Leishmania in these last two species represents new records for the Yucatan Peninsula and for Mexico. Leishmania (Leishmania) mexicana was the only species detected in the Phlebotominae species, with prevalence values that ranked between 7.41% and 33.33% from specimens collected in the sylvatic areas of Cozumel Island and Petcacab. (4) Conclusions: This study provides the first evidence of infection of Da. deleoni and Pa. undulata by L. (L.) Mexicana. In addition, the presence of three dominant haplotypes in all the evaluated localities was evidenced using the analysis of genetic diversity, and the locality of Petcacab was the one with the circulation of two new haplotypes not previously described in Mexico or neighboring countries. These results highlight the importance of intensive epidemiological surveillance due to the dynamics of transmission of Leishmania between different species.

Challenges in the real world use of classification accuracy metrics: From recall and precision to the Matthews correlation coefficient.

The accuracy of a classification is fundamental to its interpretation, use and ultimately decision making. Unfortunately, the apparent accuracy assessed can differ greatly from the true accuracy. Mis-estimation of classification accuracy metrics and associated mis-interpretations are often due to variations in prevalence and the use of an imperfect reference standard. The fundamental issues underlying the problems associated with variations in prevalence and reference standard quality are revisited here for binary classifications with particular attention focused on the use of the Matthews correlation coefficient (MCC). A key attribute claimed of the MCC is that a high value can only be attained when the classification performed well on both classes in a binary classification. However, it is shown here that the apparent magnitude of a set of popular accuracy metrics used in fields such as computer science medicine and environmental science (Recall, Precision, Specificity, Negative Predictive Value, J, F1, likelihood ratios and MCC) and one key attribute (prevalence) were all influenced greatly by variations in prevalence and use of an imperfect reference standard. Simulations using realistic values for data quality in applications such as remote sensing showed each metric varied over the range of possible prevalence and at differing levels of reference standard quality. The direction and magnitude of accuracy metric mis-estimation were a function of prevalence and the size and nature of the imperfections in the reference standard. It was evident that the apparent MCC could be substantially under- or over-estimated. Additionally, a high apparent MCC arose from an unquestionably poor classification. As with some other metrics of accuracy, the utility of the MCC may be overstated and apparent values need to be interpreted with caution. Apparent accuracy and prevalence values can be mis-leading and calls for the issues to be recognised and addressed should be heeded.
