Coma Recovery Scale-Revised Predicts Disability Rating Scale in Acute Rehabilitation of Severe Traumatic Brain Injury.

OBJECTIVE: To explore the prognostic value of the Coma Recovery Scale-Revised (CRS-R) in predicting disability outcomes in patients with severe traumatic brain injury using the Disability Rating Scale (DRS). DESIGN: Secondary analysis including linear and logistic regressions were performed. SETTING: Data were collected in a previous clinical trial. PARTICIPANTS: One hundred eighty-four participants across 3 countries (N=184). MAIN OUTCOME MEASURES: Disability Rating Scales. RESULTS: Analyses showed an inverse relation between CRS-R scores obtained at baseline and change in DRS scores at 6 weeks. Similarly, changes in CRS-R scores between baseline and 4 weeks were also found to have an inverse relation to change in DRS scores at 6 weeks. CONCLUSIONS: This study generates a tool that can be used to predict the probability that a patient with severe traumatic brain injury lands in 1 of 3 disability categories. The CRS-R may be useful in prognostication of disability in patients with severe traumatic brain injury.

Racial/Ethnic Disparities Impact the Real-World Effectiveness of a Multicomponent Maternal Smoking Cessation Program: Findings from the CTTP Cohort.

INTRODUCTION: Smoking during pregnancy adversely affects perinatal outcomes for both women and infants. We conducted a retrospective cohort study of the state-funded Comprehensive Tobacco Treatment Program (CTTP) - the largest maternal tobacco cessation program in San Bernardino County, California - to determine the real-world program effectiveness and to identify variables that can potentially improve effectiveness. METHODS: During 2012-2019, women who smoked during pregnancy were enrolled in CTTP's multicomponent behavioral smoking cessation program that implemented components of known efficacy (i.e., incentives, biomarker testing, feedback, and motivational interviewing). RESULTS: We found that 40.1% achieved prolonged abstinence by achieving weekly, cotinine-verified, 7-day abstinence during 6 to 8 weeks of enrollment. Using intention-to-treat analyses, we computed that the self-reported point prevalence abstinence rate (PPA) at the six-month telephone follow-up was 36.7%. Cohort members achieving prolonged abstinence during the CTTP were five times more likely to achieve PPA six months after CTTP. Several non-Hispanic ethnicities (Black, Native American, White, or More than one ethnicity) in the cohort were two-fold less likely (relative to Hispanics) to achieve prolonged abstinence during CTTP or PPA at six months after CTTP. This disparity was further investigated in mediation analysis. Variables such as quitting during the first trimester and smoking fewer cigarettes at enrollment were also associated with achieving PPA at six months. DISCUSSION: Racial/ethnic health disparities that have long been linked to a higher rate of maternal smoking persist even when the pregnant smoker enrolls in a smoking cessation program.

Cumulative summation analysis of learning curve for robotic-assisted hiatal hernia repairs.

BACKGROUND: Robotic-assisted laparoscopic surgery (RALS) is evolving as an important surgical approach in the field of general surgery. We aimed to evaluate the learning curve for RALS procedures involving repair of hiatal hernias. METHODS: A series of robotic-assisted hiatal hernia (HH) repairs were performed between 2013 and 2017 by a surgeon at a single institution. Data were entered into a retrospective database. Patient demographics and intraoperative parameters including console time (CT), surgery time (ST), and total operative time (OT) were examined and abstracted for learning curve analysis using the cumulative sum (CUSUM) method. Assessment of perioperative and post-operative outcomes were calculated using descriptive statistics. RESULTS: The average age of the patients was 57.4 years, average BMI was 29.9 kg/m2, median American Society of Anesthesiologists (ASA) classification was 2, and average Charlson Comorbidity Index (CCI) score was 2.8. The series had a mean CT of 132.6 min, mean ST of 145.1 min, and mean OT of 197.4 min. The CUSUM learning curve for CT was best approximated as a third-order polynomial consisting of three unique phases: the initial training phase (case 1-40), the improvement phase (case 41-85), and the mastery phase (case 86 onwards). There was no significant difference in perioperative complications between the phases. Short-term clinical outcomes were comparable with national standards and did not correlate significantly with operative experience. CONCLUSIONS: The three phases identified with CUSUM analysis represented characteristic stages of the learning curve for robotic hiatal hernia procedures. Our data suggest the training phase is achieved after 40 cases and a high level of mastery is achieved after approximately 85 cases. Thus, the CUSUM method serves as a useful tool for objectively evaluating practical skills for surgeons and can ultimately help establish milestones that assess surgical competency during robotic surgery training.

Implementation and Outcomes of a Maternal Smoking Cessation Program for a Multi-ethnic Cohort in California, USA, 2012-2019.

Smoking during pregnancy remains one of the most significant risk factors for poor birth outcomes. During 2012-2019, the Loma Linda University Health Comprehensive Tobacco Treatment Program (CTTP) used a multicomponent behavioral intervention for tobacco cessation for 1402 pregnant smokers with components of known efficacy (i.e., incentives, biomarker testing, feedback, and motivational interviewing). The CTTP cohort includes a multi-ethnic sample of pregnant women with a mean age of 27 years referred by collaborating community-based healthcare providers in San Bernardino county. Evaluation of program outcomes from 7 years of follow-up (2012-2019) creates a rich cohort dataset for implementation science research to examine the real-world effectiveness of the program. In this report, we provide a cohort profile, and 8-week prolonged abstinence (8-week PA) and relapse findings from the first year of follow-up (n = 233). We found: (1) 28.4% achieved 8-week PA, (2) At a median of 6.2 months of follow-up after achieving 8-week PA, 23.2% of enrolled subjects reported tobacco cessation, and (3) a high rate of loss to follow-up (44%). In addition, our modeling indicated that the odds of relapse/smoking after enrollment was significantly higher in young mothers, non-Hispanic mothers (White, Black/African-American), mothers in the first and third trimester, and rural mothers. Formative quantitative and qualitative research on the CTTP cohort will consider the effects of a range of implementation science (number of intervention sessions, addition of a mHealth component, distance to care) and individual (partner/household smoking, birth outcomes, NICU) outcome measures for the purpose of scaling up the CTTP model.

Validation of estimated glycaemic index and glycaemic load, stratified by race, in the Adventist Health Study-2 (AHS-2).

OBJECTIVE: Few studies have validated FFQ estimates of dietary glycaemic index (GI) and load (GL). We investigated how well our estimates of overall GI and GL from FFQs correlate with estimates from repeated 24 h recall data to validate overall GI and GL in the Adventist Health Study-2 (AHS-2). DESIGN: The AHS-2 is a prospective population-based cohort of 95 873 Seventh-day Adventist adult church members enrolled from 2002 to 2007 to investigate diet, cancer and mortality. SETTING: A 204-item FFQ was used to assess race- and gender-specific validity of GI and GL and 24 h recall data, from the calibration sub-study, were used as the reference. PARTICIPANTS: The 734 calibration study participants were randomly selected by church and included approximately equal numbers of blacks and whites but were otherwise similar to the whole cohort with respect to gender, age, education and vegetarian status. RESULTS: The deattenuated correlation coefficients for overall GI ranged from 0·19 (95 % CI -0·06, 0·53) in black men to 0·46 (95 % CI 0·40, 0·60) in black women, with both non-black men and women falling between those values (0·45 (95 % CI 0·35, 0·65) and 0·38 (95 % CI 0·27, 0·57), respectively). GL correlations were somewhat higher for all study participants. When looking at the entire cohort, the deattenuated validity correlation value for overall GI was (r 0·38, 95 % CI 0·36, 0·47) and GL was (r 0·39, 95 % CI 0·34, 0·49). CONCLUSIONS: Our findings support the cautious use of our FFQ in epidemiological studies when assessing associations of overall GI and GL with disease risk. However, observed differences by race should be considered when interpreting results.

Association between class III obesity (BMI of 40-59 kg/m2) and mortality: a pooled analysis of 20 prospective studies.

BACKGROUND: The prevalence of class III obesity (body mass index [BMI]≥40 kg/m2) has increased dramatically in several countries and currently affects 6% of adults in the US, with uncertain impact on the risks of illness and death. Using data from a large pooled study, we evaluated the risk of death, overall and due to a wide range of causes, and years of life expectancy lost associated with class III obesity. METHODS AND FINDINGS: In a pooled analysis of 20 prospective studies from the United States, Sweden, and Australia, we estimated sex- and age-adjusted total and cause-specific mortality rates (deaths per 100,000 persons per year) and multivariable-adjusted hazard ratios for adults, aged 19-83 y at baseline, classified as obese class III (BMI 40.0-59.9 kg/m2) compared with those classified as normal weight (BMI 18.5-24.9 kg/m2). Participants reporting ever smoking cigarettes or a history of chronic disease (heart disease, cancer, stroke, or emphysema) on baseline questionnaires were excluded. Among 9,564 class III obesity participants, mortality rates were 856.0 in men and 663.0 in women during the study period (1976-2009). Among 304,011 normal-weight participants, rates were 346.7 and 280.5 in men and women, respectively. Deaths from heart disease contributed largely to the excess rates in the class III obesity group (rate differences = 238.9 and 132.8 in men and women, respectively), followed by deaths from cancer (rate differences = 36.7 and 62.3 in men and women, respectively) and diabetes (rate differences = 51.2 and 29.2 in men and women, respectively). Within the class III obesity range, multivariable-adjusted hazard ratios for total deaths and deaths due to heart disease, cancer, diabetes, nephritis/nephrotic syndrome/nephrosis, chronic lower respiratory disease, and influenza/pneumonia increased with increasing BMI. Compared with normal-weight BMI, a BMI of 40-44.9, 45-49.9, 50-54.9, and 55-59.9 kg/m2 was associated with an estimated 6.5 (95% CI: 5.7-7.3), 8.9 (95% CI: 7.4-10.4), 9.8 (95% CI: 7.4-12.2), and 13.7 (95% CI: 10.5-16.9) y of life lost. A limitation was that BMI was mainly ascertained by self-report. CONCLUSIONS: Class III obesity is associated with substantially elevated rates of total mortality, with most of the excess deaths due to heart disease, cancer, and diabetes, and major reductions in life expectancy compared with normal weight.

Body size and multiple myeloma mortality: a pooled analysis of 20 prospective studies.

Multiple myeloma (MM) is a rare but highly fatal malignancy. High body weight is associated with this cancer, but several questions remain regarding the aetiological relevance of timing and location of body weight. To address these questions, we conducted a pooled analysis of MM mortality using 1·5 million participants (including 1388 MM deaths) from 20 prospective cohorts in the National Cancer Institute Cohort Consortium. Proportional hazards regression was used to calculate pooled multivariate hazard ratios (HRs) and 95% confidence intervals (CIs). Associations with elevated MM mortality were observed for higher early-adult body mass index (BMI; HR = 1·22, 95% CI: 1·09-1·35 per 5 kg/m(2) ) and for higher cohort-entry BMI (HR 1·09, 95% CI: 1·03-1·16 per 5 kg/m(2) ) and waist circumference (HR = 1·06, 95% CI: 1·02-1·10 per 5 cm). Women who were the heaviest, both in early adulthood (BMI 25+) and at cohort entry (BMI 30+) were at greater risk compared to those with BMI 18·5 ≤ 25 at both time points (HR = 1·95, 95% CI: 1·33-2·86). Waist-to-hip ratio and height were not associated with MM mortality. These observations suggest that overall, and possibly also central, obesity influence myeloma mortality, and women have the highest risk of death from this cancer if they remain heavy throughout adulthood.

Reliability of meat, fish, dairy, and egg intake over a 33-year interval in Adventist Health Study 2.

We studied Adventist Health Study 2 (AHS-2) cohort members to determine the reliability of long-term recall of adult dietary intake that occurred 33 years ago. Establishing the reliability of these measures supports studies of how dietary exposure across the life course affects risk of cancer and other noncommunicable disease outcomes. Among 1816 AHS-2 cohort members, we conducted a statistical comparison of long-term recall of meat, fish, dairy, and eggs at AHS-2 baseline with their report of current diet 33 years before AHS-2 baseline at an age of 30-60 years. Major findings are as follows: 1) a high correlation for frequency of red meat (R = 0.71), poultry (R = 0.67), and fish (R = 0.60); lower correlations for dairy (R = 0.19) and eggs (R = 0.28); 2) good concordance for dichotomous measures of red meat [sensitivity: 0.70; specificity: 0.92; positive predictive value (PPV): 0.91], poultry (sensitivity: 0.76; specificity: 0.87; PPV: 0.83), fish (sensitivity: 0.61; specificity: 0.93; PPV: 0.89), dairy (sensitivity: 0.95; specificity: 0.57; PPV: 0.99), and eggs (sensitivity: 0.95; specificity: 0.41; PPV: 0.96); negative predictive value for dairy and eggs was poor. Among older AHS-2 cohort members, we found good reliability of recall of red meat, poultry, and fish intake that occurred 33 years earlier.

Patterns of food consumption among vegetarians and non-vegetarians.

Vegetarian dietary patterns have been reported to be associated with a number of favourable health outcomes in epidemiological studies, including the Adventist Health Study 2 (AHS-2). Such dietary patterns may vary and need further characterisation regarding foods consumed. The aims of the present study were to characterise and compare the food consumption patterns of several vegetarian and non-vegetarian diets. Dietary intake was measured using an FFQ among more than 89 000 members of the AHS-2 cohort. Vegetarian dietary patterns were defined a priori, based on the absence of certain animal foods in the diet. Foods were categorised into fifty-eight minor food groups comprising seventeen major food groups. The adjusted mean consumption of each food group for the vegetarian dietary patterns was compared with that for the non-vegetarian dietary pattern. Mean consumption was found to differ significantly across the dietary patterns for all food groups. Increased consumption of many plant foods including fruits, vegetables, avocados, non-fried potatoes, whole grains, legumes, soya foods, nuts and seeds was observed among vegetarians. Conversely, reduced consumption of meats, dairy products, eggs, refined grains, added fats, sweets, snack foods and non-water beverages was observed among vegetarians. Thus, although vegetarian dietary patterns in the AHS-2 have been defined based on the absence of animal foods in the diet, they differ greatly with respect to the consumption of many other food groups. These differences in food consumption patterns may be important in helping to explain the association of vegetarian diets with several important health outcomes.

Environmental exposures, lung function, and respiratory health in rural Lao PDR.

Although the individual contributions of smoked tobacco and indoor air pollution have been identified, there are very few studies that have characterized and measured the effects of inhaled particles from a wide range of personal, household, and community practices common in rural Asia. The objective of our study was to examine the association between environmental inhaled exposures and lung function among rural males of Lao PDR. In a sample of 92 males from rural Lao PDR, study subjects completed a survey on household exposures, a physical exam, and the following measures of lung function: FEV1, FVC, and the ratio of FEV1/FVC. Our findings were as follows: a) > 80% of the subjects were exposed to indoor cooking fires (wood fuel), animal handling, dust and dirt; b) 57.6% of subjects were in the impaired range (FEV1/FVC < 0.7); and c) animal handling was negatively associated (p < 0.03) with FEV1 and FVC. Among males in rural Lao PDR, we found a high prevalence of chronic exposure to inhaled particles (animal handling, dust/dirt, smoke) and a high prevalence of impaired lung function. Findings from this pilot study indicate that associations between exposure to multiple sources of particulate matter common in rural areas and lung function need further investigation.

Spatial and Economic Proximity of Cigarette Sales to School Children in Mongolia.

Background: The Western Pacific Region has the highest rate of cigarette smoking in the world. In this region, Mongolia has ratified the WHO FCTC treaty and, as part of treaty implementation, has monitored school tobacco use in children using the 2014 Global Youth Tobacco Survey (GYTS) and 2019 GYTS. Our objective was to examine the spatial and economic factors associated with cigarette use in schoolchildren of Mongolia. Methods: The 2014 and 2019 GYTS are the most recent and comprehensive national surveys of tobacco use in schoolchildren in Mongolia and are cross-sectional, stratified, multi-stage cluster surveys of 13-15 year-old schoolchildren (7,298 in 2014, 4,146 in 2019) selected from urban and rural schools. For each survey, we conducted logistic regression modelling to examine whether spatial (proximity of cigarette sales to schools), economic (pocket money available to school children), and other environmental/contextual factors were predictors of cigarette use (all, single sticks) in schoolchildren. Results: We found that 1)the prevalence of vendors selling cigarettes near schools increased from 65% in the 2014 GYTS to 94% in the 2019 GYTS, 2) sales of cigarettes near schools were associated with increased current smoking of all cigarettes and this effect increased from a marginal 31% increase in odds in 2014 (OR [95% confidence interval(CI)]=1.31 [0.99, 1.73]) to a 416% increase in odds in 2019 (OR [95% CI]=5.16[3.31, 8.05]), 3) sales of cigarettes near schools were associated with a substantial increase in odds of smoking single cigarettes in 2014 (OR [95% CI]=1.87 [1.14,3.06]) and in 2019 (OR[95% CI]=2.70 [1.42, 5.12]). We also found that smoking of all cigarettes was higher when student pocket money exceeded the price of the cigarette pack (approximately 1.8 USD) and also when parents and/or peers were smokers. Conclusions: Despite the 2012 National Tobacco Laws banning sales of cigarettes and single cigarettes to schoolchildren near schools, the most recent national surveys (2014-2019) have shown that these sales are increasing. We provide new findings indicating that despite the higher pricing of cigarette packs (relative to the region), illicit sales of single cigarettes are targeting schoolchildren near their schools.

Estimating the impact of smoking cessation during pregnancy: the San Bernardino County experience.

We examined the relation between maternal smoking and adverse infant outcomes [low birth weight (LBW), and preterm birth (PTB)] during 2007-2008 in San Bernardino County, California-the largest county in the contiguous United States which has one of the highest rates of infant mortality in California. Using birth certificate data, we identified 1,430 mothers in 2007 and 1,355 in 2008 who smoked during pregnancy. We assessed the effect of never smoking and smoking cessation during pregnancy relative to smoking during pregnancy for the 1,843/1,798 LBW, and 3,480/3,238 PTB's recorded for 2007/2008, respectively. To describe the effect of quitting smoking during pregnancy, we calculated the exposure impact number for smoking during pregnancy. Major findings are: (1) relative to smoking during pregnancy, significantly lower risk of LBW among never smoking mothers [OR, year: 0.56, 2007; 0.54, 2008] and for smoking cessation during pregnancy [0.57, 2007; 0.72, 2008]; (2) relative to smoking during pregnancy, significantly lower risk of PTB was found for never smoking mothers [0.68, 2007; 0.68, 2008] and for smoking cessation during pregnancy [0.69, 2007; 0.69, 2008]; (3) an exposure impact assessment indicating each LBW or PTB outcome in the county could have been prevented either by at least 35 mothers quitting smoking during pregnancy or by 25 mothers being never smokers during pre-pregnancy. Our findings identify an important burden of adverse infant outcomes due to maternal smoking in San Bernardino County that can be effectively decreased by maternal smoking cessation.

Beliefs about tobacco, health, and addiction among adults in Cambodia: findings from a national survey.

There remains a very high rate of smoked and smokeless tobacco use in the Western Pacific Region. The most recent findings from national adult tobacco surveys indicate that very few daily users of tobacco intend to quit tobacco use. In Cambodia, a nation that is predominantly Buddhist, faith-based tobacco control programs have been implemented where, under the fifth precept of Buddhism that proscribes addictive behaviors, monks were encouraged to quit tobacco and temples have been declared smoke-free. In the present study, we included items on a large national tobacco survey to examine the relation between beliefs (faith-based, other) about tobacco, health, and addiction among adults (18 years and older). In a stratified, multistage cluster sample (n=13,988) of all provinces of Cambodia, we found that (1) 88-93% believe that Buddhist monks should not use tobacco, buy tobacco, or be offered tobacco during a religious ceremony; (2) 86-93% believe that the Wat (temple) should be a smoke-free area; (3) 93-95% believe that tobacco is addictive in the same way as habits (opium, gambling, alcohol) listed under the fifth precept of Buddhism; and (4) those who do not use tobacco are significantly more likely to cite a Buddhist principle as part of their anti-tobacco beliefs. These data indicate that anti-tobacco sentiments are highly prevalent in the Buddhist belief system of Cambodian adults and are especially evident among non-users of tobacco. Our findings indicate that faith-based initiatives could be an effective part of anti-tobacco campaigns in Cambodia.

Prospective Assessment of Social Determinants of Health and Length of Stay Among Emergency General Surgery and Trauma Patients.

BACKGROUND: Social determinants of health (SDOH) including insurance and substance use affect 50-90% of health outcomes, yet there remains no standard means to quantify or predict their impact. We prospectively evaluated the effects of SDOH on length of stay (LOS) and readmissions among emergency general surgery (EGS) and trauma patients. We compared these outcomes with Medicare Diagnosis Related Group (DRG) data to better quantify the impact of SDOH. METHODS: Adult (≥18 years old) EGS/trauma patients admitted July 7-28, 2020 at a Level 1 trauma center were prospectively enrolled. Primary outcomes were overall LOS, one-year readmissions, and excess LOS (eLOS), defined as days beyond DRG mean LOS. RESULTS: Assessment of SDOH among the 52 patients enrolled revealed that 5.8% of patients were homeless; 26.9% experienced substance abuse; 13.5% were uninsured on admission; and 7.7% on discharge. Mean LOS was 5 ± 4 days; 1-year readmission rate 25.0%; eLOS mean 1.75 ± 2.4 days. LOS was associated with substance use (OR 70.6 95% CI 11.7-160.4). eLOS was associated with substance use (OR 6.1, 95% CI 1.5-25.1) and public or no insurance (OR 26.0, 95% CI 4.9-138.1). No correlations were found between SDOH and readmission rates. DISCUSSION: EGS and trauma patients experience high rates of negative SDOH which affect clinical outcomes including LOS and readmissions. Medicare DRG determined eLOS is a fiscally relevant measure of the impact of SDOH and differs from LOS and readmissions. Further investigation is required to determine if eLOS can delineate the effects of other SDOH on admission outcomes for this patient population.

Differences in health and religious beliefs about tobacco use among waterpipe users in the rural male population of Egypt.

Waterpipe use is a highly prevalent form of tobacco use in the Eastern Mediterranean Region that is rooted in long-held cultural traditions that predate the use of cigarettes and present a particular challenge for tobacco control efforts. We did a stratified sampling of 4,994 Egyptian men from rural households of Egypt in order to conduct an interviewer-administered prevalence survey to identify differences in attitudes and beliefs toward smoking and smoking cessation between waterpipe users, cigarette smokers, mixed users (cigarette + waterpipe), and non-smokers. We found that cigarette smokers, mixed users, and/or non-smokers were (1) two- to ninefold more likely to believe that smoking decreased adult life expectancy and harmed a fetus than waterpipe users, (2) significantly more likely to believe that smoking is a sin ("haram") than were waterpipe users. Among tobacco users, we found that cigarette smokers and/or mixed users were significantly more likely to indicate pre-contemplation, contemplation, or intention to quit tobacco than waterpipe users. Our findings from rural Egyptian men indicate that waterpipe users are distinct from cigarette smokers in their perception that their form of tobacco use is less harmful and/or less subject to religious proscription. These beliefs may explain why waterpipe users seem less inclined to quit their tobacco habit and need to be considered in the design of tobacco cessation and prevention methods in Egypt and the region.

Cohort profile for the Loma Linda University Health BREATHE programme: a model to study continuously incentivised employee smoking cessation.

PURPOSE: The purpose of the Loma Linda University Health (LLUH) BREATHE cohort is to test the efficacy of a novel method of continuously incentivising participation in workplace smoking cessation on participation, long-term abstinence, health outcomes, healthcare costs and healthcare utilisation. PARTICIPANTS: In 2014, LLUH-a US academic medical centre and university-incentivised participation in a workplace smoking cessation programme (LLUH BREATHE) by lowering health plan costs. Specifically, LLUH introduced a Wholeness Health Plan (WHP) option that, for the smokers, continuously incentivises participation in nicotine screening and the LLUH BREATHE smoking cessation programme by offering an 'opt-in wellness discount' that consisted of 50%-53% lower out of pocket health plan costs (ie, monthly employee premiums, copayments). This novel 'continuously incentivised' model lowers annual health plan costs for smokers who, on an annual basis, attempt or maintain cessation from tobacco use. The annual WHP cost savings for smokers far exceed the value of short-term incentives that have been tested in workplace cessation trials to date. This ongoing health plan option offered to over 16 000 employees has created an open, dynamic LLUH BREATHE cohort of current and former smokers (n=1092). FINDINGS TO DATE: Our profile of the LLUH BREATHE cohort indicates that after 5 years of follow-up in a prospective cohort study (2014-2019), continuously incentivised smoking cessation produced a 74% participation (95% CI (71% to 77%)) in employer-sponsored smoking cessation attempts that were occurring less than a year after the incentive was offered. The cohort can be purposed to examine the effect of continuously incentivised cessation on cessation outcomes, health plan utilisation/costs, use of electronic nicotine delivery systems, and COVID-19 outcomes.

Hepatitis B, C, and D Virus Infection among Population Aged 10-64 Years in Mongolia: Baseline Survey Data of a Nationwide Cancer Cohort Study.

Hepatitis B, C, and D virus infections are a major public health problem, and Mongolia has one of the highest prevalences of dual and triple infections in the world. We aimed to determine the seroprevalence of hepatitis infection and dual or triple hepatitis infections among 10-64-year-olds. A questionnaire was used to identify risk factors for hepatitis infection, and seromarkers were measured by the fully automated immunologic analyzer HISCL-5000. Among a total of 10,040 participants, 8.1% of the population aged 10-64 was infected with HBV, 9.4% with HCV, and 0.4% with HBV and HCV, and the prevalence of the disease varied by age, sex, and the area of residence. Young people were particularly unaware of their hepatitis infection status. A small proportion of children aged 10 to 19 years and the majority of adults younger than 30 years were unaware of their HBV and HCV infection. Men were also more likely to be unaware of their HBV and HCV infection status than women. The results suggested that the prevalence of infection in the general population is high and that most people are unaware that they are infected or have become chronic carriers. Identifying mono-, co-, or triple-infection status is critical to prevent the rapid progression of liver disease among the Mongolian population.

Microbial contamination in the communal-use Lao tobacco waterpipe.

BACKGROUND: The use of the Asian tobacco waterpipe (TWP) in the Lao People's Democratic Republic represents a potential communal source of infectious disease. This practice of smoking can lead to weakened defences of a smoker's respiratory epithelium, making the smoker vulnerable to respiratory diseases such as coronavirus disease 2019, tuberculosis and others. METHODS: This study evaluated the water quality and hygiene factors among 43 smokers of five villages in rural Luang Namtha Province. Water samples were collected from participant's TWPs and assessed for the presence of Escherichia coli, coliforms and aerobic plate count (APC) bacteria using the 3M Petrifilm. RESULTS: The microbial indicator testing results were 95% positive for the APC, 38% positive for coliforms and 17% positive for the E. coli indicator. The concentrations were highest for the APC, with an average of 106 colony forming units (cfu)/ml, followed by coliforms with <100 cfu/ml and lowest for E. coli with <10 cfu/ml. Most TWPs were infrequently cleaned, heavily used and contained a warm, brown-coloured water. CONCLUSIONS: The warm, dark and moist internal water container may facilitate microbial survival and growth. The use of a TWP adds several unstudied modes of transmission to a complex and common biobehavioural and environmental pathogen exposure. Future TWP cessation activities should be tailored to consider risks of infectious disease transmission.

Factors Associated with COVID-19 Vaccine Hesitancy in Mongolia: A Web-Based Cross-Sectional Survey.

Vaccine acceptance in the general public is essential in controlling the coronavirus disease 2019 (COVID-19) pandemic. The study aimed to assess the COVID-19 vaccine hesitancy in the adult population of Mongolia, and determine the associated factors. A total of 2875 individuals from urban and rural areas were recruited, and completed an online survey. Older age, urban residence, previous vaccination, high education, good knowledge of side effects, and a personal view of the importance of vaccines were associated with vaccine acceptability, whereas gender and religion were not. Receiving COVID-19 vaccine information from official government pages was related to a higher acceptance rate. Reliance on social media as a source of COVID-19 vaccine information was associated with high level of vaccine hesitancy. The side effects and the type of the COVID-19 vaccine were a major reason for hesitation. Countering false information regarding COVID-19 vaccines on social media, and promoting vaccine importance on general news websites is necessary. Moreover, providing clear and direct educational materials through official communication channels on the safety and efficacy of COVID-19 vaccines alongside information on COVID-19 symptoms, vaccine side effects, and location of vaccine administration centers among the younger populations, rural residents, and those with lower education is needed.

Pilot Feasibility Study of Incorporating Whole Person Care Health Coaching Into an Employee Wellness Program.

Prior research supports positive health coaching outcomes, but there is limited literature on the integration of employer-sponsored health coaching into employee wellness strategy. The aim of our mixed methods study was to assess feasibility, acceptability, and preliminary efficacy of incorporating a whole-person care model of health coaching into an employee wellness program (i.e., weight loss, smoking cessation) that is made available by an employer-sponsored health plan. For the quantitative study, eligible employees and covered spouses (n = 39) from Loma Linda University Health were recruited into a novel, 12-week, whole person care intervention that combined health coaching and health education and examined outcomes from surveys detailing the participants' experience and biometric data from the intervention and maintenance periods. For the qualitative study, data were collected through key informant interviews from three health coaches and six intervention participants who were recruited via random sampling. Health coaching was well-received by the participants, and led to a slight albeit positive behavioral change for obesity. A significant decrease in body mass index occurred over 12 weeks of intervention (-0.36 kg/m2, p = 0.016), that did not continue during the maintenance phase (-0.17 kg/m2, p = 0.218). Qualitative findings indicated improved personal health awareness, accountability, motivation, and self-efficacy along with goal setting and barrier overcoming skills among the key themes. Our pilot study findings identify positive behavior change effects of an employee health intervention based on a whole person care model of health coaching with integrated health education, and also identify the need for methods to maintain behavior change (i.e., mHealth, peer-support) post-intervention. Further investigation in randomized controlled trials is the next step in this research.
