Abstract Background: Studying the characteristics of Aedes mosquito habitats is essential to control the mosquito population. The objective of this study was to identify the breeding sites of Aedes larvae and their distribution in the Chattogram. We conducted an entomological survey in 12 different sub-district (Thana) under Chattogram city, Bangladesh, during the late monsoon (August to November) 2019. The presence of different wet containers along with their characteristics and the existence of immature mosquitoes were recorded in field survey data-form. Larvae and/or pupae were collected and brought to the laboratory for identification. Results: We estimated the overall house index, container index, and the Breteau index and performed multiple logistic regression analyses to identify habitats more likely to be positive for Aedes larvae/pupae. Out of a total of 704 wet containers of 37 different types from 216 properties where 52 (7.39%) containers were positive for Aedes larvae or pupae. Tire, plastic buckets, plastic drums, and coconut shells were the most prevalent container types. The plastic group possessed highest container productivity (n=50) whereas vehicle and machinery group was the highest efficient (1.83). Among the total positive properties, 8% were infested with Aedes aegypti, 2% were Aedes albopictus and 1% contains both species Ae. aegypti and A. albopictus. The overall house index was 17.35%, container index was 7% and the Breteau index was 24.49. Containers in multistoried House had significantly lower positivity in compare to independent house. Binary logistic regression represented that containers having shade were 6.7 times more likely to be positive than the containers without shade (p< 0.01). Conclusions: These findings might assist the authorities to identify the properties, containers, and geographical areas with different degrees of risk for mosquito control interventions to prevent dengue and other Aedes-borne diseases transmissions.

Larvae and/or pupae were collected and brought to the laboratory for identification. Results Different indices like house index, container index, and the Breteau index were estimated. The multiple logistic regression analysis was applied to identify habitats that were more likely to be positive for Aedes larvae/pupae. A total of 704 wet containers of 37 different types from 216 properties were examined, where 52 (7.39%) were positive for Aedes larvae or pupae. Tire, plastic buckets, plastic drums, and coconut shells were the most prevalent container types. The plastic group possessed the highest container productivity (50%) whereas the vehicle and machinery group was found as most efficient (1.83) in terms of immature Aedes production. Among the total positive properties, 8% were infested with Aedes aegypti, 2% with Aedes albopictus, and 1% contained both species Ae. aegypti and A. albopictus. The overall house index was 17.35%, the container index was 7%, and the Breteau index was 24.49. Containers in multistoried houses had significantly lower positivity compared to independent houses.

Abstract Background Sex determination is one of the leading criterion in identification and verification of an individual. However, the potential roles of differences in adjacent fingerprint white line count (FWLC) in sex inference are not well elucidated in the literature especially among Hausa population. The study was conducted to determine sexual dimorphism and predict sex using adjacent digit FWLC difference (adj. DFWLCD) among Hausa population of Kano state, Nigeria. Methods The study population involved 300 participants. FWLC was determined from a plain fingerprint captured using live scanner. The formula for adj. DFWLCD of thumb and fifth digit is dR15 for right hand. The same applied for possible combination in cephalocaudal direction. Mann-Whitney and t tests were used for comparison of variables between sexes. Binary logistic regression analyses were employed for determination of sex. Results We observed a significantly larger adj. DFWLCD in males compared with females in most of the digit combination. A significant sexual dimorphism was observed in most of the adj. DFWLCD involving ring digit in both right (dR14, dR24, and dR34) and left (dL14, dL24, and dL34). The best discrimination was observed in adjacent FWLC difference of second and fourth digits in both right and left digits (dR24 and dL24). This was further supported by stepwise logistic regression analyses. Conclusion The adj. DFWLCD exhibits sexual dimorphism. The best prediction potentials were found to be dR24 and dL24 for right and left hands respectively.

Background: Multiple medications are required to effectively manage chronic kidney disease (CKD) and associated complications, posing the risk of poor medication adherence. Objectives: To measure medication adherence levels and to investigate the potential predictors of sub-optimal medication adherence in pre-dialysis patients with CKD. Methods: A prospective study was conducted in the medical and nephrology outpatients’ clinics in Maiduguri. Non-dialysis patients with CKD stages 1–4 aged 18 years and above were recruited through their physicians. The level of medication adherence was determined using Morisky Medication Adherence Scale. Descriptive statistics were used to summarize patients’ background characteristics. Multivariate binary logistic regression analyses were performed to investigate the significantly potential predictors of sub-optimal medication adherence at a p < 0.05. Results: There were 107 participants (48.6%) who had high medication adherence, while 97 (44.1%), and 16 (7.3%) of them had moderate adherence, and low adherence, respectively. The univariate analysis revealed that medication adherence level differed significantly with the number of medications taken daily by patients ( p < 0.05). Multivariate logistic regression analyses did not reveal a significant independent predictor of sub-optimal medication adherence. Conclusion: A majority of the participants reported sub-optimal medication adherence. The independent variables considered did not significantly predict sub-optimal medication adherence in the study population. Nevertheless, the study findings highlight the importance of clinical pharmacists’ CKD management supportive care to help improve medication adherence.

Abstract. The objective of the present study was to investigate factors that affect sugar sweetened beverage (SSB) intake in rural, southern college students in the US. The majority of the participants were male (58 %) and Caucasian (63 %). The average total SSB consumption was 79.4 fl oz/day (2.35 L/d). Results of binary logistic regression analyses of total SSB intake greater than 57.4 fl oz/day (1.8 L/d) versus less than 57.4 fl oz/day showed that factors associated with greater odds for high SSB intake were age greater than 20 years old (odds ratio [OR] = 3.551, 95 % confidence interval [CI] = 1.385 - 9.104, p = 0.008) and being African American (OR = 3.477, 95 % CI = 1.291 - 9.363, p = 0.013). Results of binary logistic regression analyses of total bottled water intake greater than 39.4 fl oz/day (median) versus less than 39.4 fl oz/day showed that consuming alcohol was significantly related to an increased probability of drinking more than 39.4 fl oz (1.17 L/d) of bottled water per day (median; OR = 2.914, 95 % CI = 1.223 - 6.943, p = 0.016). Culturally sensitive strategies are needed to raise awareness for making healthy beverage choices when dining on campus to effectively reduce college student’s SSB consumption.

The purpose of the present study was to clarify the relationship between the development of the yips in baseball, overcommitment to sport, and resilience. Participants: 482 Japanese baseball players who belonged to a university baseball team (mean age = 19.43 years, SD = 1.00) were included in the analysis. A face sheet, a questionnaire on the yips, the scale of overcommitment to sport, and the Bidimensional Resilience Scale. Binary logistic regression analyses were used to evaluate the extent, to which overcommitment and resilience predicted the presence or absence of developing the yips in baseball. The results indicated the overcommitment was significant but the two factors of resilience, namely, innate resilience and acquired resilience were not significant. Thus, it is possible that the higher the tendency of overcommitment to baseball, the higher the possibility of developing the yips. It is recommended that a longitudinal study be conducted to examine what factors are involved in the process in depth. The purpose of the present study was to clarify the relationship between the development of the yips in baseball, overcommitment to sport, and resilience. Binary logistic regression analyses revealed that while overcommitment was significant in the development of the yips, innate and acquired resilience were not. It is recommended that a longitudinal study be conducted to examine what factors are involved in the process in depth.

While research in recent years has investigated the influence of pornography consumption on sexually aggressive behavior, research on the relationship between pornography and experienced victimization is sparse. The current study sought to explore female sexual victimization and its relationship with pornography consumption and alcohol use at two universities ( N = 483). Binary logistic regression analyses indicate that both pornography and alcohol consumption were unique predictors of self-reported victimization for college females and that the combined effect of pornography and alcohol dramatically increases the odds of victimization. Results are discussed in the context of pornography’s impact on the minimization of sexually aggressive acts in real life and campus rape culture.

This study sought to explore whether body image self-consciousness during sexual relations predicts whether and for what reasons individuals send sexts. A series of ordinal and binary logistic regression analyses revealed that increased body image self-consciousness during sexual relations predicted consensual but unwanted instances of sexting for men and women, a lower frequency of sending sexts among heterosexual individuals, and a lesser likelihood of sending sexts in order to flirt. Body image self-consciousness, however, was not predictive of sending sexts in general or sending sexts in order to ‘feel sexy’. This research provides support for the negative relationship between body image self-consciousness and sexual agency across gender, and suggests that individuals affected by body image anxieties might be prone to technology-mediated abuse. Study limitations and recommendations for future research are discussed.

Abstract This study describes changes in dining practices and provider perspectives on meal-related challenges due to the coronavirus disease (COVID-19) pandemic. An online survey was disseminated between July and September 2020 through stakeholder networks and social media with 1,036 respondents. Altered dining practices included residents eating in rooms (54.3%), spacing residents in common areas for meals (69.3%), and disposable dish use (44.9%). The most common mealtime challenges were reduced socializing opportunities at meals (29.3%), inadequate staffing (22.8%), reduced family/volunteer help (16.7%), and assisting residents to eat (10.5%). Many participants (72.2%) felt conflict balancing safety and relationship-centred care. Geographic region, home size, building age, respondent’s job title, pre-pandemic relationship-centred practices, and mealtime satisfaction, and some pandemic-initiated practices were associated with mealtime challenges and feeling conflicted in binary logistic regression analyses. Considering trade-offs between safety and relational aspects of mealtimes during the pandemic is crucial.

Abstract Background Use of sugammadex is associated with fewer postoperative pulmonary complications. This study investigated the relationship between sugammadex and postoperative pulmonary complications (PPC) in specific patients with respiratory dysfunction. Methods The authors reviewed the electronic medical and anesthesia records of patients with respiratory dysfunction who had laparoscopic gastric or intestinal surgery at a single center between May 01, 2018, and December 31, 2019. The patients were divided into the sugammadex group and the non-sugammadex group, based on whether or not they received sugammadex. Binary logistic regression analyses were used to characterize the differences in incidence of PPC. Results A total of 112 patients were included, of which 46 patients (41.07%) received sugammadex. In the logistic regression analysis, the incidences of PPC were fewer in the sugammadex group. Postoperative fever [Odds Ratio (OR) 0.330; 95% Confidence Interval (CI) 0.137–0.793, p = 0.0213], postoperative ICU admission (OR 0.204; 95% CI 0.065 to 0.644, p = 0.007), cough (OR 0.143; 95% CI 0.061 to 0.333, p < 0.001), pleural effusion (all) (OR: 0.280; 95% CI 0.104 to 0.759, p = 0.012), pleural effusion (massive) (OR: 0.142; 95% CI 0.031 to 0.653, p = 0.012), and difficulty in breathing (OR: 0.111; 95% CI 0.014 to 0.849, p = 0.039) showed significant differences between the two groups. Conclusions Sugammadex-mediated reversal of neuromuscular blockade can reduce the PPC in patients with respiratory dysfunction.
