Poor sleep quality association with higher lung cancer risk: a nested case-control study

Background Little is known about the relationship between sleep quality and lung cancer incidence. Thus, this study was conducted to investigate the potential connection between sleep quality and lung cancer incidence. Methods We performed and selected a nested case–control study that included 150 lung cancer cases and 150 matched controls based on the Lianyungang cohort. Univariate and multivariate logistic regression was utilized to investigate the connection between potential risk factors and lung cancer incidence risk. Results In this study, the average age of participants was 66.5 ± 9.1 years, with 58.7% being male, and 52.7% reportedly experiencing sleep quality problems. The results of multivariate logistic regression showed that poor sleep quality was connected to an increased lung cancer incidence risk (P = 0.033, odds ratio = 1.83, 95% confidence interval = [1.05–3.19]) compared with those with good sleep quality. The stratified analyses showed a significantly positive connection between poor sleep quality (vs. good sleep quality) and cancer risk in smokers (vs. non-smoker, P for interaction = 0.085). The combined effect analysis indicated that smokers with poor sleep quality suffered from a 2.79-fold increase in cancer incidence rates when compared with non-smokers with good sleep quality. Conclusions Poor sleep quality was positively connected to an increased lung cancer incidence risk. In addition, among those individuals with poor sleep quality, smoking increased the lung cancer incidence risk.
Precious metals in volcanic-type nickel sulfide deposits in Western Australia; I, Relationship with the composition of the ores and their host rocks

We examine the relationship between the bulk composition of the sulfide fraction and the abundances of Pd, Pt, Ir and Au in volcanic-type nickel sulfide deposits of Western Australia. We also review abundance of these elements in samples representing the liquid and olivine components of the komatiitic ultramafic sequences that bost the deposits. Results from representative samples of ore, recalculated, to l00Vo sulfides, show varying degrees of positive correlation between the tenor of precious metals and the Ni content. The correlation is good for Ir and Pd and weak to moderate for Pt, whereas Au values show no regular trends. Our study of ore profiles, sulfide stringers and mineral separates, however, has shown us that considerable effort and care is required to establish average precious metal values in volcanic-type deposits. Samples representing the high-Me liquid fraction of the magmas that coexisted with original sulfide melts have Pd:Ir ratios similar to those of the sulfides; this fact indicates that these liquids exerted the dominant influence on the relative partitioning of precious metals between silicate magmas and sulfide melts. A wide range of sulfide-melt compositions were associated with only a narrow rangp of $ilicate-melt compositions; factors other than the bulk composition of the silicate melt controlled the composition of the sulfide melt.
Not So Cool! Peri-Operative Hypothermia and Its Complications in Cardiac Surgery: Insights from an Indian Study

: This study investigates the prevalence of peri-operative hypothermia in cardiac surgery patients and its associated complications, particularly focusing on the Indian context. We analyzed data from patients undergoing both on and off-pump cardiac surgeries, tracking temperature changes and their correlation with bleeding and blood transfusion requirements. Our findings highlight a significant occurrence of hypothermia and its potential complications, underscoring the need for improved peri-operative temperature management in cardiac surgery patients. Purpose: The purpose of this study is to evaluate the prevalence and consequences of peri-operative hypothermia in patients undergoing cardiac surgery in India, with a specific focus on bleeding and blood transfusion requirements. Methods: The data set included with sixty seven patients which are observed and recorded by our perfusion students prospectively. Temperature was recorded at 3 time points, once prior to entering the operating room, and once at incision and once after chest closure. The estimated blood loss volumes were obtained from anesthesia charts. Results: Of the 67 patients, 1 was excluded due to error in data collection. One mortality was recorded. The average temperature of the entire cohort at pre-op, incision and closure were 36.6 o C, 35.1 o C, 34.6 o C respectively. The OPCABG gp, experienced a significantly higher average drop in temperature than in ON PUMP gp (2.44 o C vs. 0.95 o C). The average estimated blood loss (EBL) in the OPCAB gp (726ml) was slightly more than ON PUMP gp (675 ml). The average blood product transfusion (Prod-Tfn) of the entire cohort was 1.9 Units (0-10). The OPCABG gp received significantly less Prod-Tfn compared to ONPUMP group (1.4 units vs.3.4 units). We further divided our cohort into two groups as >3 o C drop in temperature (>3°Gp) and <3 o C drop in temperature (<3°Gp). An EBL in the >3 o Gp, 820ml (259ml-1900ml) was significantly more than <3 o Gp, 667ml (300ml-1500ml). Among the OPCABG patients, the EBL in >3 o Gp was also significantly higher than the <3 o Gp (836ml vs 658ml). Similarly, in among the OPCABG patients, the average Prod-Tfn in>3°Gp was significantly more the <3°Gp (2.25units vs. 1.78 units). Conclusion: The magnitude of hypothermia was associated with increased risk of bleeding and blood product transfusions. This seems to affect OPCABG patients more. Maintaining normothermia might be useful in peri-operative management of patients undergoing cardiac surgery.
The Russian version of the Abbreviated Math Anxiety Scale: psychometric properties in adolescents aged 13–16 years

This study is the first to assess the internal consistency and factor validity of the Abbreviated Math Anxiety Scale (AMAS) in a sample of Russian adolescents as well as gender differences and gender invariance. The study included 4,218 adolescents in grades 7–9 (M = 14.23, SD = 0.92). Internal consistency, measured with Cronbach’s alpha, was high. Analysis of the factor structure revealed the best correspondence of the second-order factor model, which included two scales (learning math anxiety and math evaluation anxiety) and the general scale of math anxiety. There were greater gender differences in the all three scales. Analysis of gender invariance demonstrated that the mathematics anxiety construct was uniform in boys and girls. These findings confirm the reliable psychometric properties and validity of the AMAS, enabling its use in adolescents.
Las parejas reconstituidas en España: un fenómeno emergente con perfiles heterogéneos

espanolEste articulo da a conocer el perfil sociodemografico de los nucleos reconstituidos espanoles con algun hijo menor de 18 anos. En la ultima decada se ha producido un incremento de estos nucleos que se explica en gran medida por la aportacion de las parejas mixtas e inmigrantes. Ademas de la caracteristica nacional, en estos destacan tres rasgos: elevada cohabitacion, gran diferencia de edad entre sus miembros y mayor precariedad laboral que en los nucleos biparentales. Aun asi, el analisis revela una gran heterogeneidad de perfiles, diferenciados segun la presencia o no de hijos comunes y el sexo y nacionalidad del progenitor que aporta a los hijos no comunes. En este sentido lo que mas determina que una pareja reconstituida tome la decision de tener hijos es precisamente el numero de hijos no comunes, siendo mucho menos importante quien los aporta. EnglishThis paper examines the demographic profi le of couples in reconstituted nuclei with at least one child under 18 in Spain. In the last decade there has been an increase in these nuclei that is largely explained by the presence of couples of immigrant and mixed immigrant-Spanish origin. In addition to national origin, three other characteristics of these couples stand out: high rates of cohabitation, age difference between members of the couple and economic precariousness. However, our analysis reveals large heterogeneity in their profi les, mainly differentiated by the presence or absence of shared children as well as the sex and nationality of the parent who brings children into the relationship. We also fi nd that the most important determinant in the decision to have a child in common in a reconstituted relationship is the number of non-common children, being much less important which parent brought them into the reconstituted family.
Exploring the Historical Background and Clinical Implications of Electrocardiogram in the Context of Chagas Disease Research

ABSTRACT Chagas disease (CD) remains one of the most significant endemic diseases in Latin America. Approximately 30% of individuals with CD develop the cardiac form, the main determinant of morbidity and mortality, which is characterized by typical electrocardiogram (ECG) changes caused by chronic chagasic cardiopathy (CCC). This review accentuates to how crucial it is for research teams and reference centers that treat patients with CD to standardize ECG in CCC. This was a non-systematic review of the literature. ECG is the most widely used examination in the diagnosis and evaluation of CCC, and it is also employed in epidemiological surveys, risk stratification for cardiovascular events and death, and monitoring the clinical progression of the disease. Carlos Chagas and Eurico Villela published the first work addressing CCC in 1922. Other works followed, including the study by Evandro Chagas' which was the first to perform ECG in CD, culminating in Francisco Laranja's seminal work in 1956. Since the 1980s, standardizations and ECG reading codes for CD have been established. This standardization aimed to code complex arrhythmias and characteristic ventricular conduction disorders and standardize ECG readings for clinical and epidemiological studies in CD. Nearly all existing electrocardiographic abnormalities can be found in CD, with a predominance of abnormalities in the formation and conduction of cardiac stimuli. The complex and heterogeneous substrate of CD with varied electrocardiographic manifestations poses a significant challenge when comparing studies involving patients with CCC, emphasizing the need for ECG standardization in CD.
Sustainable Recovery of Platinum Group Metals from Spent Automotive Three-Way Catalysts through a Biogenic Thiosulfate-Copper-Ammonia System

This study explores an eco-friendly method for recovering platinum group metals from a synthetic automotive three-way catalyst (TWC). Bioleaching of palladium (Pd) using the thiosulfate-copper-ammonia leaching processes, with biogenic thiosulfate sourced from a bioreactor used for biogas biodesulfurization, is proposed as a sustainable alternative to conventional methods. Biogenic thiosulfate production was optimized in a gas-lift bioreactor by studying the pH (8–10) and operation modes (batch and continuous) under anoxic and microaerobic conditions for 35 d. The maximum concentration of 4.9 g S2O32− L−1 of biogenic thiosulfate was reached under optimal conditions (batch mode, pH = 10, and airflow rate 0.033 vvm). To optimize Pd bioleaching from a ground TWC, screening through a Plackett–Burman design determined that oxygen and temperature significantly affected the leaching yield negatively and positively, respectively. Based on these results, an optimization through an experimental design was performed, indicating the optimal conditions to be Na2S2O3 1.2 M, CuSO4 0.03 M, (NH4)2SO4 1.5 M, Na2SO3 0.2 M, pH 8, and 60 °C. A remarkable 96.2 and 93.2% of the total Pd was successfully extracted from the solid at 5% pulp density using both commercially available and biogenic thiosulfate, highlighting the method’s versatility for Pd bioleaching from both thiosulfate sources.

SWOT means the assessment of strength (S), weakness (W), opportunity (O), and threat (T). The research utilized in-depth interviews, observational, and ethnographic methods to gather data from community members, heritage managers, and government workers, which was then analyzed qualitatively. Through the findings, a SWOT analysis reveals monolith sites' strengths are their distinctive traits, while their weaknesses include a sensitive environment and inadequate environmental management. Based on the findings and the SWOT analysis, the strategic plan adopted includes baseline information, accessibility, collaboration, improving the living standard of the host community, environmental education and research, community participation and marketing.
Analysis of Factors Influencing the Decision of Cooked Food Vendors on KNUST Campus to Practice Book Keeping

Proper bookkeeping practices are essential for business performance and sustainability. Unfortunately, most small and medium-scale businesses, including food vending businesses, do not practice proper bookkeeping and, thus, suffer in making financing and investment decisions regarding their operations. Using cross-sectional data from a sample of 70 vendors randomly selected from a population of 200 cooked food vendors on the KNUST campus, the research investigated the factors influencing the vendor's decision to practice proper bookkeeping in their business operations. Descriptive and inferential statistics were used to analyze the data. About 76% of the food vendors were aware of bookkeeping practices and acknowledged the value of bookkeeping as a tool to monitor their financial performance and identify strategies to enhance profitability. Two-thirds of the vendors practiced bookkeeping, with 56% keeping financial records and a third keeping inventory records. Among the various factors examined, age, educational level, awareness, startup capital, profitability, access to credit, and experience were identified as the significant factors affecting the decision of a cooked food vendor to practice bookkeeping. The study recommends the need for food vendors to consider bookkeeping as a priority activity to enhance their financial accountability, business growth, and informed decisions about their operations, and thus the overall performance and sustainability of food vending businesses.
Factors Associated with Pediatric Constipation- A Single Center Study

Introduction: Constipation or difficulty in bowel movement is a common problem in children. It is often results from without any previous illness or previous painful bowel movements. Dietary influences such as low fiber intake and inadequate hydration play a role too. Many factors have been associated with the occurrence of constipation. Aim of the study: The aim of this study was to investigate the factors associated with pediatric constipation and its management. Methods: This cross-sectional study was conducted in out-patient Department of Pediatrics surgery in Enam Medical College and Hospital, Savar, Dhaka, Bangladesh, during the period from July to December 2022. Total 180 patients with constipation were included in this study. Result: Our study of 180 children, average age was 2.4 years and slightly more in females, investigated factors relating to constipation. Most of the children had constipation for 6-12 months and more; and some children had constipation for 3-4 years, with symptoms such as large hard stool (95.0%), painful defecation (88.3%), and abdominal pain or crying (71.1%). Some children had per rectal bleeding and perianal mass or growth that is sentinel piles. A large number of clinical and therapeutic factors were associated with chronic constipation. Conclusion: The findings of this study highlighted the prominence of symptoms like large, hard, and painful defecation of children. With notable findings such as inadequate fluid and fiber intake and change in dietary habit during weaning period and lack of toilet training play an important role in producing constipation.
Altered Red Blood Cell Fatty Acid and Serum Adipokine Profiles in Subjects with Obesity

Background: Adipokines, as well as the fatty acid profile of red blood cell (RBC) membranes, are known to play important roles in the development and progression of metabolic complications induced by obesity. Thus, the objective of this study is to compare the serum adipokine profile and the RBC membrane fatty acid profile of normal-weight and obese adults, and to analyze their relationship with serum biochemical parameters. Methods: An observational case–control study was performed in 75 normal-weight and obese adult subjects. Biochemical serum parameters, eight serum adipokines and the RBC membrane fatty acid profiles were measured. Associations between parameters were established using regression analysis. Results: Subjects with obesity showed increased levels of leptin, fibroblast growth factor 21 (FGF21) and overexpressed nephroblastoma (NOV/CCN3), decreased adiponectin, and similar levels of vaspin and chemerin compared to normal-weight subjects. Significant positive and negative correlations were found with triglycerides and high-density lipoprotein-cholesterol (HDL-c), respectively. An increase in the total ω-6 fatty acids in the RBC membrane fatty acid profiles in subjects with obesity was observed, because of higher levels of both dihomo-γ-linolenic acid (DGLA) and arachidonic acid (AA), and decreased total ω-3 fatty acids, mainly due to lower levels of docosahexaenoic acid (DHA). The ω-6/ω-3 ratio in the RBCs was significantly higher, suggesting an inflammatory status, as was also suggested by a reduced adiponectin level. A negative association between DGLA and adiponectin, and a positive association between DHA and serum triglycerides, was observed. Conclusions: Important alterations in serum adipokine and RBC fatty acid profiles are found in subjects with obesity.
Adaptation strategies to reduce the effect of climate change (utilization of indigenous systems by the fisher folks) in the coastal region of Nigeria

Climate change is now very much with us, so all countries must work to reduce their greenhouse gas emissions and learn how to cope with the impacts of climatic change. Developing countries, however, have relatively small greenhouse gas emissions, so mitigation is less important for them. Adaptation is more relevant for poorer nations because of their relative vulnerability to the impacts of climate change. The present study examined the utilization of the Indigenous Systems as a means of reducing the effect of climate change in the coastal region of Nigeria using Ilaje Local Government Area (LGA) of Ondo state as a case study. The objectives of the study includes: determination of the socio-economic characteristics of the respondents in the study area, identification of the indigenous system (IS) peculiar to the study area, determination of the relationship between the most utilized IS and the demographic characteristics of the respondents, identification of the problems inherent in fishing and identification of the problems caused by IS in fishing. Eighty-four (84) respondents were purposively selected from two communities in Ilaje LGA. The results of the study revealed some of the indigenous system which the respondents were familiar with and their effects. It was also revealed from this study that most of the respondents were male and a large percentage of the fishing population in Ilaje LGA believed that ISs are better than modern systems, they also believed that fishing is not profitable without the use of IS. Chisquare analysis was used to determine the relationship between the six most utilized IS and the demographic characteristics of the respondents. A 5Likert scale was used to answer some perception questions while Chronbach alpha was used to test the reliability of the survey instrument used in the study.
Optimizing Bucking Decisions in Korean Red Pine: A Dynamic Programming Approach to Timber Profitability

Poor bucking decisions in forest stands can result in underestimating the profitability of timber sales. This study focuses on Pinus densiflora, commonly known as a red pine in Korea, which has often been underutilized as pulp and chips, leading to reduced profit margins. This study aimed to improve bucking decisions for red pine by analyzing the potential values in different log types and the profitability of manufacturing lumber products compared to pulp chips. A log sawing simulation model was developed using dynamic programming. This study optimized sawing patterns and estimated net profits for varying log sizes within the lumber market in Korea. The findings reveal that manufacturing lumber products from 3.6 m and 2.7 m logs can yield net profits 861% and 723% higher, respectively, than producing pulp chips from 1.8 m logs. Notably, sawing 3.6 m logs resulted in an average net profit 24% higher than from 2.7 m logs. These results advocate for more strategic bucking decisions based on potential timber sale profits and the end-uses of logs, especially in trees with large diameters at breast height (DBH), which can produce high-quality logs and should be bucked into long sawlogs whenever possible. Additionally, the study emphasizes the importance of practicing timber cruise to appraise the stumpage value of forest stands more accurately, moving beyond mere volume estimation to include tree type and expected volume. By implementing these practices, timber sale profits and the overall value of forest stands in Korea can be significantly enhanced. This approach not only benefits the economic aspect of forestry but also encourages sustainable and efficient resource management.
