Determinants of child survival practice among caregivers in internally displaced persons' camps in Abuja Municipal Area Council, Nigeria.

BACKGROUND: Child survival remains a major public health challenge in the sub-Saharan region of Africa, especially Nigeria. The Boko Haram crisis, which has aggravated this, has led to the displacement of many people in the north-eastern region, including children under five. This study investigated the determinants of child survival practice among caregivers in internally displaced persons' (IDP) camps in Abuja Municipal Area Council (AMAC), Nigeria. METHODOLOGY: A cross-sectional design was used to collect data on determinants of child survival practice from 312 caregivers in five purposively selected IDP camps in AMAC using the snowball sampling technique. Data were analysed using univariate, bivariate, and multivariate statistics at 5% level of significance. RESULTS: The mean age of respondents was 29.6 ± 6.72 years. There was a significant (p < 0.05) relationship between the predisposing, reinforcing, enabling and environmental factors studied and child survival practice. Findings also indicated that all factors were significant (p < 0.05) predictors of child survival practice with the reinforcing factor being the major predictor (ß = 0.38; t = 6.08). CONCLUSION: Attention needs to be paid to all factors, particularly the reinforcing factor of social support in order to promote optimal child survival practice among caregivers in AMAC IDP camps. Collaboration with social work professionals would be an added benefit to enhance social support.

What are the predisposing factors for periprosthetic fractures following total hip arthroplasty? - a National Inpatient Sample-based study.

INTRODUCTION: With a progressive rise in the number of total hip arthroplasties (THA) over the past decades, the proportion of patients sustaining peri-prosthetic fractures (PPF) has been substantially increasing. In this context, the need for clearly understanding the factors predisposing patients to PPF following THA and the impact of these adverse complications on the overall healthcare burden cannot be understated. MATERIALS AND METHODS: Based upon the Nationwide Inpatient Sample (NIS) database, the patients who underwent THA in the United States between 2016 and2019 (with ICD-10 CMP code) were identified. The patients were divided into 2 groups; group A - patients who sustained PPF and group B - those who did not. The information about the patients' demographic profile, medical comorbidities; and hospital admission (including length of stay and expenditure incurred) were analysed; and compared between the 2 groups. RESULTS: Overall, 367,890 patients underwent THA, among whom 4,425 (1.2%) sustained PPF (group A). The remaining patients were classified under group B (363,465 patients). On the basis of multi-variate analysis (MVA), there was a significantly greater proportion of females, elderly patients, and emergent admissions (p < 0.001) in group A. The length of hospital stay, expenditure incurred and mortality were also significantly higher (p = 0.001) in group A. Based on MVA, Down's syndrome (odd's ratio 3.15, p = 0.01), H/O colostomy (odd's ratio 2.09, p = 0.008), liver cirrhosis (odd's ratio 2.01, p < 0.001), Parkinson's disease (odd's ratio 1.49, p = 0.004), morbid obesity (odd's ratio 1.44, p < 0.001), super obesity (odd's ratio 1.49, p = 0.03), and H/O CABG (coronary artery bypass graft; odd's ratio 1.21, p = 0.03) demonstrated significant association with PPF (group A). CONCLUSION: Patients with PPF require higher rates of emergent admission, longer hospital stay and greater admission-related expenditure. Female sex, advanced age, morbid or super obesity, and presence of medical comorbidities (such as Down's syndrome, cirrhosis, Parkinson's disease, previous colostomy, and previous CABG) significantly enhance the risk of PPF after THA. These medical conditions must be kept in clinicians' minds and close follow-up needs to be implemented in such situations so as to mitigate these complications.

Utilisation of indigenous knowledge to control gastrointestinal nematodes in Southern Africa.

Gastrointestinal nematodes (GIN) exacerbate the impact of droughts on the survival of cattle. The inadequacies of the conventional system make it increasingly important to explore indigenous knowledge (IK) to create drought-tolerant and GIN resilient herds. The objective of the study was to assess the indigenous strategies for controlling GIN during droughts. Face-to-face interviews with experts on IK were conducted to give insight into the importance, methods and ranking of GIN control. The experts identified 86 cattle that were used to test their assertions. The control methods used were identifying cattle that were susceptible to high GIN loads using predisposing factors, diagnosis of GIN burdens using faecal appearance, and treatment using phytotherapy. Experts ranked predisposing factors as the most critical control strategy and identified body condition, class, sex, coat colour, pregnancy status and lactation status as predisposing factors to high GIN burdens. Thin, older, dark-coloured cattle, as well as pregnant and lactating cows, were considered susceptible to GIN. However, pregnancy status, coat colour and sex were significantly associated with high GIN burdens. Cows were 2.6 times more likely to have high GIN burdens than bulls. Dark-coloured cattle were 3.5 times more likely to have high GIN burdens than light-coloured ones, and the likelihood of pregnant cows was 4.9 times higher than non-pregnant cows. A dark-coloured pregnant cow was extremely susceptible to high GIN burdens. In conclusion, knowledge of predisposing factors informs selection decisions when purchasing foundation stock. Cattle that are susceptible to high GIN loads are prioritised during droughts or culled where resources are scarce.

Risk of seizures in a population of women with BRCA-positive metastatic breast cancer from an electronic health record database in the United States.

BACKGROUND: Incidence and risk factors for seizures among women with advanced breast cancer (BC) and brain metastases are not well characterized across treatment-related or clinical subtypes. This study leveraged a large real-world dataset to describe incidence and risk factors for seizures in BRCA-associated metastatic breast cancer. METHODS: The Optum® de-identified electronic health records database was used. Females with a BC diagnoses between 2008 and 2018, with clinic visits 12 months before BC index date, evidence of BRCA mutation (BRCA+), evidence of metastasis, and no previous cancers were included. Analyses were stratified by the overall BRCA+ cohort and 4 molecular phenotypes: HER2+/HR- (human epidermal growth factor 2/hormone receptor), HER2-/HR+, HER2+/HR+, and triple negative BC (TNBC; HER2-/HR-). Seizures were identified using diagnosis codes and natural language processing. Incidence, occurrence rates, and cumulative incidence of seizures from the diagnosis of metastasis to the end of follow up were calculated. Comparisons were made between phenotypes and stratified on PARP inhibitor use, diagnosed brain metastases, history of seizures, and anticonvulsants use before BC. All comparisons included age at metastasis, number of prior lines of treatment, and metastasis location as covariates. RESULTS: 27.8% of 7941 BRCA+ patients had ≥1 seizure over a mean follow-up time of 2.35 years. Incidence and occurrence rates were 11.83 (95% CI: 11.35-12.33) and 201.3 (95% CI: 198.05-204.50), respectively, per 100 person-years. HER2-/HR+ and TNBC patients had the lowest and highest seizure incidence rates, respectively (10.94 [95% CI: 10.23-11.71] and 16.83 [95% CI: 15.34-18.46]). With HER2-/HR+ as the reference group in a competing risk analysis, TNBC (hazard ratio, HR = 1.35; 95%CI: 1.21, 1.52; p < 0.001) and HER2+/HR- (HR = 1.29; 95%CI: 1.07, 1.56; p < 0.01) patients had a greater risk of seizures. Patients with diagnosed brain metastases or a history of seizures had higher seizure rates. Incidence trended higher with PARP inhibitor use, but patient numbers were low. CONCLUSIONS: This study provides novel real-world evidence on seizure incidence rates in BRCA+ BC patients, even those without diagnosed brain metastases, and underscores the need to understand patients' tumor phenotypes when assessing seizure risk. These findings may have implications for clinical practice and assessment of benefit-risk ratios of new therapeutic agents.

A study on the fungal rhinosinusitis: Causative agents, symptoms, and predisposing factors.

Background: In natural conditions, inhaled fungi are considered a part of the microflora of nasal cavities and sinuses. However, subsequent to the protracted use of corticosteroids and antibacterial agents, suppression of the immune system by chemotherapy, and poor ventilation, these fungi can become pathogens. Fungal colonization in the nose and paranasal sinuses is a prevalent medical issue in immunocompetent and immunosuppressed patients. In this study, we aimed to categorize fungal rhinosinusitis (FRS) among immunocompetent and immunosuppressed patients and identified the etiologic agents of disease by molecular methods. Materials and Methods: A total of 74 cases were evaluated for FRS. Functional endoscopic sinus surgery was performed for sampling. The clinical samples were examined by direct microscopy with potassium hydroxide 20% and subcultured on Sabouraud Dextrose Agar with chloramphenicol. Polymerase chain reaction sequencing was applied to identify causative agents. Results: Thirty-three patients (44.6%) had FRS. Principal predisposing factors were antibiotic consumption (n = 31, 93.9%), corticosteroid therapy (n = 22, 66.6%), and diabetes mellitus (n = 21, 63.6%). Eyesore (n = 22, 66.6%), proptosis (n = 16, 48.5%), and headache (n = 15, 45.4%) were the most common clinical manifestations among patients. Rhizopus oryzae (n = 15, 45.4%) and Aspergillus flavus (n = 10, 30.3%) were the most prevalent fungal species. Conclusion: Diagnosis and classification of FRS are crucial, and a lack of early precise diagnosis can lead to a delay in any surgical or medical management. Since there are a variety of treatments for FRS, accurate identification of etiologic agents should be performed based on phenotypic and molecular methods.

Female breast cancer incidence predisposing risk factors identification using nationwide big data: a matched nested case-control study in Taiwan.

BACKGROUND: Breast cancer is an umbrella term referring to a group of biologically and molecularly heterogeneous diseases originating from the breast. Globally, incidences of breast cancer has been increasing dramatically over the past decades. Analyses of multiple clinical "big data" can aid us in clarifying the means of preventing the disease. In addition, predisposing risk factors will be the most important issues if we can confirm their relevance. This study aims to provide an overview of the predisposing factors that contribute to a higher possibility of developing breast cancer and emphasize the signs that we ought to pay more attention to. METHODS: This is a matched nested case-control study. The cohort focused on identifying the eligible risk factors in breast cancer development by data screening (2000-2013) from the Taiwan National Health Insurance Research Database (NHIRD) under approved protocol. A total of 486,069 females were enrolled from a nationwide sampled database, and 3281 females was elligible as breast cancer cohort, 478,574 females who had never diagnosed with breast cancer from 2000 to 2013 were eligible as non-breast cancer controls, and matched to breast cancer cases according to age using a 1:6 ratio. RESULTS: We analyzed 3281 breast cancer cases and 19,686 non-breast cancer controls after an age-matched procedure. The significant predisposing factors associated with breast cancer development including obesity, hyperlipidemia, thyroid cancer and liver cancer. As for patients under the age of 55, gastric cancer does seem to have an impact on the development of breast cancer; compared with their counterparts over the age of 55, endometrial cancer appears to exhibit an evocative effect. CONCLUSIONS: In this nationwide matched nested case-control study, we identified obesity, hyperlipidemia, previous cancers of the thyroid, stomach and liver as risk factors associated with breast cancer. However, the retrospective nature and limited case numbers of certain cancers still difficult to provide robust evidence. Further prospective studies are necessitated to corroborate this finding in order to nip the disease in the bud. TRIAL REGISTRATION: The studies involving human participants were reviewed and approved by the China Medical University Hospital [CMUH104-REC2-115(AR-4)].

In pursuit of biomarkers for predicting susceptibility to activity-based anorexia in adolescent female rats.

OBJECTIVE: Identifying risk factors that contribute to the development of anorexia nervosa (AN) is critical for the implementation of early intervention strategies. Anxiety, obsessive-compulsive behavior, and immune dysfunction may be involved in the development of AN; however, their direct influence on susceptibility to the condition remains unclear. Here, we used the activity-based anorexia (ABA) model to examine whether activity, anxiety-like behavior, compulsive behavior, and circulating immune markers predict the subsequent development of pathological weight loss. METHOD: Female Sprague-Dawley rats (n = 44) underwent behavioral testing before exposure to ABA conditions after which they were separated into susceptible and resistant subpopulations. Blood was sampled before behavioral testing and after recovery from ABA to screen for proinflammatory cytokines. RESULTS: Rats that were vulnerable to pathological weight loss differed significantly from resistant rats on all key ABA parameters. While the primary measures of anxiety-like or compulsive behavior were not shown to predict vulnerability to ABA, increased locomotion and anxiety-like behavior were both associated with the extent of weight loss in susceptible but not resistant animals. Moreover, the change in expression of proinflammatory markers IL-4 and IL-6 evoked by ABA was associated with discrete vulnerability factors. Intriguingly, behavior related to risk assessment was shown to predict vulnerability to ABA. DISCUSSION: We did not find undisputable behavioral or immune predictors of susceptibility to pathological weight loss in the ABA rat model. Future research should examine the role of cognition in the development of ABA, dysfunction of which may represent an endophenotype linking anorectic, anxiety-like and compulsive behavior. PUBLIC SIGNIFICANCE: Anorexia nervosa (AN) has among the highest mortality rates of all psychiatric disorders and treatment options remain limited in their efficacy. Understanding what types of risk factors contribute to the development of AN is essential for implementing early intervention strategies. This study describes how some of the most common psychological features of AN could be used to predict susceptibility to pathological weight loss in a well-established animal model.

Invasive candidiasis in a neonatal intensive care unit in Fukuoka.

BACKGROUND: Invasive candidiasis (IC) is a leading cause of morbidity and mortality in preterm infants. The objective of this study was to determine the prevalence of IC infection in newborns in the neonatal intensive care unit (NICU) of a tertiary hospital in Japan, and to identify specific predisposing factors for IC. METHODS: We retrospectively collected data on demographics, clinical characteristics, and outcomes of infants with IC, who were discharged from a tertiary NICU in Japan between January 2009 and December 2020. We compared predisposing factors associated with the occurrence of early-onset IC (EOIC < 72 h) and late-onset IC (LOIC ≥ 72 h) with those of early-onset and late-onset bacterial sepsis. RESULTS: Between January 2009 and December 2020, 3,549 infants were admitted to the NICU, including 344 extremely-low birthweight (ELBW) infants. Eleven infants (including nine ELBW infants) had IC (incidence 0.31%), and the mortality rate of IC was 0%. Four (36%) infants had EOIC and seven (64%) had LOIC. All those with EOIC presented with skin lesions and 86% with LOIC had thrombocytopenia. Maternal vaginal Candida colonization was a more specific predisposing factor for EOIC, while gestational age <26 weeks, broad-spectrum antibiotic use, prior bacterial infection, prior gastrointestinal (GI) surgery, and GI diseases were more specific predisposing factors for LOIC. CONCLUSIONS: The findings suggest that maternal vaginal Candida colonization and skin lesions in ELBW infants may contribute to early recognition of EOIC. LOIC should be suspected if ELBW infants with several predisposing factors of LOIC have thrombocytopenia.

Latest update on predictive indicators, risk factors and 'Omic' technologies research of retained placenta in dairy cattle - A review.

Retained placenta is a pathological condition defined as failure to expel foetal membranes within 12-24 h after parturition. It instigates important financial losses to the dairy industry causing considerable economic loss. It is a multifactorial disorder. Although different hypotheses have been proposed, contradictory results and no single factor explains the development of the disease. This indicates that there are overall significant gaps in our knowledge about the various factors affecting the aetiopathology and pathobiology of the retained placenta. Thus, it will be of great interest to investigate the potential contributing factors that influence the occurrence of RP which provide us with the mechanisms to avoid the occurrence of the disease. In addition, different predictive indicators of RP should be a part of our research, thus providing the essential procedures applied to deal with the disease and the development of novel therapeutic and prophylactic strategies in its management. Furthermore, lately, the molecular role takes attention to understanding its effect in the occurrence of the disease. Such information might help dairy scientists in the future to design better management and preventive practices for RP in dairy cows.

The prevalence, clinical features, and related factors of dentin hypersensitivity in the Turkish population.

OBJECTIVES: The purpose of this study was to identify the prevalence and predisposing and etiologic factors of dentin hypersensitivity (DH), as well as the demographic characteristics of patients. MATERIALS AND METHODS: The 1210 patients were examined. The research was based on a two-step investigation: questionnaire and clinical examination. DH was evaluated by the response of the patient to tactile and air-blast stimuli. Loss of attachment and gingival recession of sensitive teeth was measured on the buccal and lingual surfaces. Also, the tooth wear of sensitive teeth was graded on the buccal and lingual surfaces. Comparisons of nonnormally distributed continuous variables were performed using the Mann-Whitney U test and Kruskal-Wallis one-way analysis of variance (ANOVA) and Dunn's post hoc test. Comparisons of categorical variables were performed using Pearson's chi-square, Fisher's exact chi-square, Yates's chi-square, and the Monte Carlo chi-square test. RESULTS: One hundred twenty-four patients reported DH, showing a prevalence for self-reported DH of 10.2%. Eight hundred forty teeth were diagnosed as having DH, giving a clinical diagnosis rate of DH of 29.4%. Females (76.8%), the 31-40 years age group (26%), housewives (36.8%), and high school education level (38%) had the highest prevalence of DH as demographic properties. A cold stimulus was the most common stimuli trigger for hypersensitivity (97.1%). Occasional pain (55.5%) showed the highest prevalence in terms of frequency of DH. A higher rate of DH was found with the use of medium brushes (47.4%) and brushing twice per day (59.4%) for 1-2 min (56.2%) with the circular method (33.8%) as oral hygiene habits. The buccal surface of the lower right central incisors (5.7%) had the highest prevalence. The most affected teeth by DH were incisors (38.4%). The buccal surfaces (86.3%) of teeth showed a higher high prevalence of DH compared with the lingual surface (52.7%), similar to gingival recession (40.9% vs. 15.7%) and loss of attachment (68.3% vs. 42.6%). CONCLUSIONS: Clinically diagnosed DH was more common than self-reported DH. Some factors related to patients such as sex (female), the 31-40 years age group, housewives, high school students, using medium brushes, brushing twice per day, and the circular brushing method were more likely to have a risk for DH. Also, buccal surfaces of teeth, gingival recession, and loss of attachment on the buccal surface of teeth should be considered as predisposing factors for DH. CLINICAL RELEVANCE: To control and prevent DH, clinicians should consider patients' demographics, predisposing factors, and etiologic factors.

The Influence of Social Support, Help-Seeking Attitudes and Help-Seeking Intentions on Older Australians' use of Mental Health Services for Depression and Anxiety Symptoms.

This study investigated the influence of predisposing factors (social support, help-seeking attitudes and help-seeking intentions) on older Australian adults' use of mental health services for depression and/or anxiety symptoms. Participants were 214 older Australian adults (61% female; aged between 60 and 96 years; M = 75.15 years, SD = 8.40 years) who completed a self-report questionnaire that measured predisposing factors and lifetime mental health service use for depression and/or anxiety symptoms. Higher levels of social support predicted non-use of mental health services. When this relationship was serially mediated by help-seeking attitudes and help-seeking intentions, it predicted mental health service use for depression and/or anxiety. Older adults are less likely to seek help for depression and/or anxiety symptoms unless members of their social support network encourage positive help-seeking attitudes, which lead to positive help-seeking intentions and the subsequent use of mental health services.

Relationship between predisposing and facilitating factors: Does it influence the risk of developing peri-operative pressure injuries?

This study examined the relationship between the personal predisposing factors of patients and the severity of pressure injuries (PIs) developed during surgery. This retrospective cohort study collected 439 cases of peri-operative PIs. Using binary logistic regression to identify the variables associated with PI severity, the effects of interactions between associated variables were then tested. The results of this study revealed that among the personal predisposing factors, only higher patient age (P = .001) and higher body mass index (P < .001) posed a greater risk of stage 2 PIs or higher. Among the surgery-related facilitating factors, only patients who were placed in the prone position during surgery and patients who lost ≥1000 mL of blood during surgery were at greater risk of stage 2 PIs or higher, compared, respectively, to those placed in the supine position and those who lost ≤100 mL of blood. Furthermore, the amount of blood lost during surgery moderated the influence of age on PI severity. For elderly patients who are expected to lose a large blood volume during surgery or lose an immeasurable amount of blood due to the use of cardiopulmonary bypass, taking more precautionary measures to prevent PIs is recommended.

Characteristics and Contributing Factors Related to Nonsteroidal Anti-Inflammatory Drugs Hypersensitivity.

INTRODUCTION: Hypersensitivity to nonsteroidal anti-inflammatory drugs (NSAIDs) is reported to be the most common drug hypersensitivity. The aim of this study was to evaluate the characteristics of self-reported NSAID hypersensitivity and identify patients at high risk of NSAID hypersensitivity. METHODS: Patients who presented at a single tertiary care hospital between January-December 2017 with reported NSAID hypersensitivity were evaluated. Clinical information obtained from a review of medical records was further supplemented with data gained from a telephone-administered questionnaire. RESULTS: From a total of 535 patients with reported NSAID hypersensitivity, 301 were included in the study. The mean age of onset of NSAID hypersensitivity reaction was 30.3 ± 14.9 years old. A total of 84 patients (27.9%) were hypersensitive to 2 or more chemically unrelated NSAIDs. The leading NSAID hypersensitivity was to propionic acid derivatives (73%) followed by acetic acid derivatives (28.9%). Immediate reaction (≤1 h) was identified in 171 patients (57.8%), and angioedema was the most frequently reported symptom (179 patients, 59.5%), followed by urticaria and anaphylaxis in 85 (28.2%) and 62 (20.6%) patients, respectively. A drug provocation test was performed on 53 patients, and NSAID hypersensitivity was confirmed in 38 patients (71.6%). The independent factors identified, which could predict NSAID hypersensitivity, were personal history of allergic rhinitis/chronic rhinosinusitis (AR/CRS), onset of NSAID hypersensitivity over 15 years old, and immediate reaction. CONCLUSION: Angioedema was the most typical symptom, and propionic acid derivatives were the most frequently reported culprit drugs. The significant risk factors predicting NSAID hypersensitivity were personal history of AR/CRS, onset of NSAID hypersensitivity reaction over 15 years old, and immediate reaction.

Predisposing factors of long-term responsiveness in a cardio-metabolic cohort: Tehran Lipid and Glucose Study.

BACKGROUND: Non-participation in cohort studies, if associated with both the exposure and occurrence of the event, can introduce bias in the estimates of interest. This study aims to identify factors associated with follow-up participation in Tehran Lipid and Glucose Study, a large-scale community-based prospective study in West Asia. METHODS: A sample of 10,368 adults from TLGS was included in the analysis. All analyses were split according to sex and age groups (20-39, 40-59, and 60 years). The associations between socio-demographic, health, and lifestyle factors with response rate were identified using the Generalized Estimating Equations model. RESULTS: Over the median of 15.7 years of follow up the response rate was 64.5%. The highest response rate was observed in those aged 40-59 years for both sexes. Current smokers had lower odds of response in both sexes for all age groups, ranging from 0.51 to 0.74, p < 0.01. In young adults, being single (OR = 0.79, OR = 0.57, p ≤ 0.01, respectively for men and women) and unemployed (OR = 0.73, OR = 0.76, p ≤ 0.01, respectively for men and women) in both sexes, high physical activity in men (OR = 0.77, p < 0.01), high education (OR = 0.75, p = 0.02) and obesity (OR = 0.85, p = 0.05) in women were associated with lower response rate. For the middle-aged group, diabetes in men (OR = 0.77, p = 0.05) and hypertension (OR = 0.84, p = 0.05), and having a history of cancer (OR = 0.43, p = 0.03) in women were factors associated with lower response rates. Finally, interventions for both sexes (OR = 0.75, OR = 0.77, p ≤ 0.05, respectively for men and women) and being divorced/widow in women (OR = 0.77, p = 0.05) were the factors associated with the lower response rate in the elderly. CONCLUSIONS: Long-term participation was influenced by socio-demographic, health, and lifestyle factors in different sex- and age-specific patterns in TLGS. Recruitment strategies targeting these factors may improve participant follow-up in longitudinal studies.

Predisposing factors to acquisition of acute respiratory tract infections in the community: a systematic review and meta-analysis.

BACKGROUND: Preventing respiratory tract infections (RTIs) could have profound effects on quality of life, primary care workload, antibiotic prescribing and stewardship. We aimed to identify factors that increase and decrease RTI acquisition within Organisation for Economic Cooperation and Development (OECD) member countries. METHODS: Systematic search of Medline, Embase, Cochrane and ISI Web of Knowledge for studies conducted up to July 2020 reporting predisposing factors for community RTI acquisition. Pooled odds ratios were calculated using a random-effects model. RESULTS: 23 studies investigated risk factors associated with community-acquired pneumonia (n = 15); any RTI (n = 4); influenza like illness (n = 2); and lower RTI (n = 2). Demographic, lifestyle and social factors were: underweight BMI (pooled odds ratio (ORp 2.14, 95% CI 1.58 to 2.70, p = 0.97); male sex (ORp 1.30, 95% CI 1.27 to 1.33, p = 0.66); contact with pets (ORp 1.35, 95% CI 1.16 to 1.54, p = 0.72); contact with children (ORp 1.35, 95% CI 1.15 to 1.56, p = 0.05); and ex-smoking status (ORp 1.57, 95% CI 1.26 to 1.88, p = 0.76). Health-related factors were: chronic liver condition (ORp 1.30, 95% CI 1.09 to 1.50, p = 0.34); chronic renal condition (ORp 1.47, 95% CI 1.09 to 1.85, p = 0.14); and any hospitalisation in previous five years (ORp 1.64, 95% CI 1.46 to 1.82, p = 0.66). CONCLUSIONS: We identified several modifiable risk factors associated with increased likelihood of acquiring RTIs in the community, including low BMI, contact with children and pets. Modification of risk factors and increased awareness of vulnerable groups could reduce morbidity, mortality and antibiotic use associated with RTIs. PROSPERO REGISTRATION: CRD42019134176.

Lifestyle, psychological stress, and incidence of adolescent constipation: results from the Toyama birth cohort study.

BACKGROUND: We aimed to clarify the predisposing factors for adolescent constipation in a longitudinal study, because while factors associated with childhood constipation have been reported, prospective studies on the incidence of constipation are lacking. METHODS: We enrolled 5540 adolescents aged 12 to 13 years from the Toyama Birth Cohort Study-a community-based prospective study examining children's health. The incidence of constipation, defined as bowel movement frequency of less than once every 2 days, was surveyed during the three-year period from baseline (grade 4) to follow-up (grade 7). Multivariate logistic regression analyses were performed to explore the association between the incidence of adolescent constipation and their lifestyle variables. RESULTS: A total of 261 adolescents (4.7%) developed constipation during the three-year period. Female sex (odds ratio [OR] = 2.62,) overweight (OR = 0.60), and infrequent intake of fruits (OR = 1.50) at baseline were associated with the incidence of constipation. Furthermore, factors related to lifestyle changes and psychological status such as skipping breakfast (OR = 1.73), becoming physically inactive (OR = 1.55), and being persistently irritated (OR = 1.80) were significantly associated with the incidence of constipation. CONCLUSION: Our prospective study demonstrated that female sex, insufficient fruit intake, and deteriorating lifestyles such as skipping breakfast and becoming inactive during the 3-year period were associated with the incidence of adolescent constipation. Beyond anecdotal, maintaining a healthy lifestyle is recommended to reduce the incidence of adolescent constipation.

Genetic Predisposition and its Heredity in the Context of Increased Prevalence of Dermatophytoses.

Dermatophytosis is a widespread disease with high prevalence and a substantial economic burden associated with costs of treatment. The pattern of this infectious disease covers a wide spectrum from exposed individuals without symptoms to those with acutely inflammatory or non-inflammatory, chronic to invasive, and life-threatening symptoms. Moreover, the prevalence of cutaneous fungal infections is not as high as might be expected. This curious disparity in the dermatophyte infection patterns may suggest that there are individual factors that predispose to infection, with genetics as an increasingly well-known determinant. In this review, we describe recent findings about the genetic predisposition to dermatophyte infections, with focus on inheritance in families with a high frequency of dermatophyte infections and specific host-pathogen interactions. The results of studies indicating a hereditary predisposition to dermatophytoses have been challenged by many skeptics suggesting that the varied degree of pathogenicity and the ecological diversity of this group of fungi are more important in increasing sensitivity. Nonetheless, a retrospective analysis of the hereditary propensity to dermatophytoses revealed at least several proven genetic relationships such as races, CARD9 deficiency, HLA-DR4 and HLA-DR8 type and responsible genes encoding interleukin-22, ß-defensin 2 and 4 as well as genetic defects in dectin-1, which increased the prevalence of the disease in families and were involved in the inheritance of the proneness in their members. In future, the Human Genome Diversity Project can contribute to elucidation of the genetic predisposition to dermatophytoses and provide more information.

Atrial Fibrillation: Pathogenesis, Predisposing Factors, and Genetics.

Atrial fibrillation (AF) is the most frequent arrhythmia managed in clinical practice, and it is linked to an increased risk of death, stroke, and peripheral embolism. The Global Burden of Disease shows that the estimated prevalence of AF is up to 33.5 million patients. So far, successful therapeutic techniques have been implemented, with a high health-care cost burden. As a result, identifying modifiable risk factors for AF and suitable preventive measures may play a significant role in enhancing community health and lowering health-care system expenditures. Several mechanisms, including electrical and structural remodeling of atrial tissue, have been proposed to contribute to the development of AF. This review article discusses the predisposing factors in AF including the different pathogenic mechanisms, sedentary lifestyle, and dietary habits, as well as the potential genetic burden.

Death in delirious palliative-care patients occurs irrespective of age: A prospective, observational cohort study of 229 delirious palliative-care patients.

OBJECTIVES: Patients with terminal illness are at high risk of developing delirium, in particular, those with multiple predisposing and precipitating risk factors. Delirium in palliative care is largely under-researched, and few studies have systematically assessed key aspects of delirium in elderly, palliative-care patients. METHODS: In this prospective, observational cohort study at a tertiary care center, 229 delirious palliative-care patients stratified by age: <65 (N = 105) and ≥65 years (N = 124), were analyzed with logistic regression models to identify associations with respect to predisposing and precipitating factors. RESULTS: In 88% of the patients, the underlying diagnosis was cancer. Mortality rate and median time to death did not differ significantly between the two age groups. No inter-group differences were detected with respect to gender, care requirements, length of hospital stay, or medical costs. In patients ≥65 years, exclusively predisposing factors were relevant for delirium, including hearing impairment [odds ratio (OR) 3.64; confidence interval (CI) 1.90-6.99; P < 0.001], hypertension (OR 3.57; CI 1.84-6.92; P < 0.001), and chronic kidney disease (OR 4.84; CI 1.19-19.72; P = 0.028). In contrast, in patients <65 years, only precipitating factors were relevant for delirium, including cerebral edema (OR 0.02; CI 0.01-0.43; P = 0.012). SIGNIFICANCE OF RESULTS: The results of this study demonstrate that death in delirious palliative-care patients occurs irrespective of age. The multifactorial nature and adverse outcomes of delirium across all age in these patients require clinical recognition. Potentially reversible factors should be detected early to prevent or mitigate delirium and its poor survival outcomes.

Delirium is associated with an increased morbidity and in-hospital mortality in cancer patients: Results from a prospective cohort study.

OBJECTIVE: Delirium is a frequent complication in advanced cancer patients, among whom it is frequently underdiagnosed and inadequately treated. To date, evidence on risk factors and the prognostic impact of delirium on outcomes remains sparse in this patient population. METHOD: In this prospective observational cohort study at a single tertiary-care center, 1,350 cancer patients were enrolled. Simple and multiple logistic regression models were utilized to identify associations between predisposing and precipitating factors and delirium. Cox proportional-hazards models were used to estimate the effect of delirium on death rate. RESULTS: In our patient cohort, the prevalence of delirium was 34.3%. Delirium was associated inter alia with prolonged hospitalization, a doubling of care requirements, increased healthcare costs, increased need for institutionalization (OR 3.22), and increased mortality (OR 8.78). Predisposing factors for delirium were impaired activity (OR 10.82), frailty (OR 4.75); hearing (OR 2.23) and visual impairment (OR 1.89), chronic pneumonitis (OR 2.62), hypertension (OR 1.46), and renal insufficiency (OR 1.82). Precipitating factors were acute renal failure (OR 7.50), pressure sores (OR 3.78), pain (OR 2.86), and cystitis (OR 1.32). On multivariate Cox regression, delirium increased the mortality risk sixfold (HR 5.66). Age ≥ 65 years and comorbidities further doubled the mortality risk of delirious patients (HR 1.77; HR 2.05). SIGNIFICANCE OF RESULTS: Delirium is common in cancer patients and associated with increased morbidity and mortality. Systematically categorizing predisposing and precipitating factors might yield new strategies for preventing and managing delirium in cancer patients.
