Abstract Background Alternative payment models (APMs) are methods through which insurers reimburse health care providers and are widely used to improve the quality and value of health care. While there is a growing movement to utilize APMs for substance use disorder (SUD) treatment services, they have rarely included SUD prevention strategies. Challenges to using APMs for SUD prevention include underdeveloped program outcome measures, inadequate SUD prevention funding, and lack of clarity regarding what prevention strategies might fit within the scope of APMs. Methods In November 2023, the Substance Abuse and Mental Health Services Administration (SAMHSA), through a contract with Westat, convened an expert panel to refine a preliminary conceptual framework developed for utilizing APMs for SUD prevention and to identify strategies to encourage their adoption. Results The conceptual framework agreed upon by the panel provides expert consensus on how APMs could finance a variety of prevention programs across diverse populations and settings. Additional efforts are needed to accelerate the support for and adoption of APMs for SUD prevention, and the principles of health equity and community engagement should underpin these efforts. Opportunities to increase the use of APMs for SUD prevention include educating key groups, expanding and promoting the SUD prevention workforce, establishing funding for pilot studies, identifying evidence-based core components of SUD prevention, analyzing the cost effectiveness of APMs for SUD prevention, and aligning funding across federal agencies. Conclusion Given that the use of APMs for SUD prevention is a new practice, additional research, education, and resources are needed. The conceptual framework and strategies generated by the expert panel offer a path for future research. SUD health care stakeholders should consider ways that SUD prevention can be effectively and equitably implemented within APMs.

Background This study aimed to investigate the potential association between the combination of low physical activity and low dietary diversity with mild cognitive impairment (MCI) in older Japanese adults. Methods Data from 600 older adults (mean age, 74.1±6.4 years; women, 62.0%) were analyzed. We evaluated dietary variety based on the Food Frequency Score (FFS; maximum 30 points) by assessing the 1-week consumption frequencies of ten foods. An FFS of ≤16 indicated low dietary diversity. We assessed MCI using the National Center for Geriatrics and Gerontology Functional Assessment Tool. Physical activity levels was determined based on participant responses to two questions: “Do you engage in moderate levels of physical exercise or sports aimed at health?” and “Do you engage in low levels of physical exercise aimed at health?” Participants who responded “No” to both questions were classified as having low physical activity levels. We classified the participants into robust, low-dietary diversity, low-physical activity, and coexistence groups. Results The overall prevalence of MCI was 20.7%, with rates in the robust, low dietary diversity, low physical activity, and coexistence groups of 17.7%, 24.7%, 25.0%, and 41.9%, respectively. Multiple logistic regression analysis revealed that low dietary diversity and physical activity were associated with MCI in older adults (odds ratio=2.80, 95% confidence interval 1.22–6.28). Conclusion The results of the present study demonstrated the association of the co-occurrence of low dietary diversity and low physical activity with MCI. Older adults with both risk factors may require early detection, as well as physical activity and dietary interventions.

Background The use of transport other than cars is a modifiable factor in the association between driving cessation and social frailty. Clarifying this relationship may serve as a new preventive measure against social frailty among current non-drivers. This study examined the potential association of driving status and transport use with social frailty, as well as between the frequency of transport use and social frailty, among current non-drivers. Methods This study included 977 middle-aged and older adults (average age, 65.3±4.8 years). The participants were classified as transport users (more than a few times a week) and transport non-users (less than a few times a month). Based on driving status and transport use, the groups were further classified into current driver, current non-driver/transport user, and current non-driver/transport non-user groups. The relationships between driving status, transport use, and social frailty were examined using multiple logistic regression. Results The current non-driver group and the transport non-user group were significant association with a higher social frailty. The current non-driver/transport user group showed no association with social frailty compared with the current driver group. The odds ratio for the social frailty rate for The current non-driver/transport non-user group was 2.14 (95% confidence interval, 1.25–3.73). Conclusions Participants who neither drive nor take transport showed significant associations with increased social frailty. Compared with current driver/transport use, current non-driver/transport non-use was associated with social frailty.

Introduction: There have been conflicting data regarding the relationship between sepsis-bundle adherence and mortality. Moreover, little is known about how this relationship may be moderated by the anatomic source of infection or the location of sepsis declaration. Methods: This was a multi-center, retrospective, observational study of adult patients with a hospital discharge diagnosis of severe sepsis or septic shock. The study included patients who presented to one of three Los Angeles County Department of Health Services (DHS) full-service hospitals January 2012 to December 2014. The primary outcome of interest was the association between sepsis-bundle adherence and in-hospital mortality. Secondary outcome measures included in-hospital mortality by source of infection, and the location of sepsis declaration. Results: Among the 4,582 patients identified with sepsis, overall mortality was lower among those who received bundle-adherent care compared to those who did not (17.9% vs. 20.4%; p=0.035). Seventy-five percent (n=3,459) of patients first met sepsis criteria in the ED, 9.6% (n=444) in the intensive care unit (ICU) and 14.8% (n=678) on the ward. Bundle adherence was associated with lower mortality for those declaring in the ICU (23.0% adherent [95% confidence interval{CI} {16.8–30.5}] vs. 31.4% non-adherent [95% CI {26.4–37.0}]; p=0.063), but not for those declaring in the ED (17.2% adherent [95% CI {15.8–18.7}] vs. 15.1% non-adherent [95% CI {13.0–17.5}]; p=0.133) or on the ward (24.8% adherent [95% CI {18.6–32.4}] vs. 24.4% non-adherent [95% CI {20.9–28.3}]; p=0.908). Pneumonia was the most common source of sepsis (32.6%), and patients with pneumonia had the highest mortality of all other subsets receiving bundle non-adherent care (28.9%; 95% CI [25.3–32.9]). Although overall mortality was lower among those who received bundle-adherent care compared to those who did not, when divided into subgroups by suspected source of infection, a statistically significant mortality benefit to bundle-adherent sepsis care was only seen in patients with pneumonia. Conclusion: In a large public healthcare system, adherence with severe sepsis/septic shock management bundles was found to be associated with improved survival. Bundle adherence seems to be most beneficial for patients with pneumonia. The overall improved survival in patients who received bundle-adherent care was driven by patients declaring in the ICU. Adherence was not associated with lower mortality in the large subset of patients who declared in the ED, nor in the smaller subset of patients who declared in the ward.

Background: Empagliflozin is a relatively newer glucose-lowering drug (GLD) with many extra-glycemic benefits. To date, no study has evaluated the efficacy and safety of empagliflozin in Bangladeshi patients with type 2 diabetes mellitus (T2DM). Objectives: To assess the efficacy and safety of empagliflozin as an add-on to ongoing GLDs in Bangladeshi adults with uncontrolled T2DM. Materials and Methods: This real-world, multicenter, open-label, prospective study was carried out at 21 sites throughout Bangladesh from 1 February 2022 to 31 July 2022. Patients with T2DM who met the criteria had Empagliflozin added to their existing GLD treatment, with necessary modifications to their ongoing medication regimen. The efficacy and safety data were collected 12 weeks after empagliflozin initiation. Results: Out of 1449 subjects initiating empagliflozin, 1340 subjects [age 50.3 ± 9.0 years, male 52.5%, overweight/obese 94.4%, insulin-treated 25.7%, baseline hemoglobin A1c (Hba1c) 9.9 ± 1.4%] completed the study. At 12 weeks, the reduction in HbA1c was 1.6% (95% CI 1.5-1.6, P < 0.001); 12.5% of the study subjects achieved HbA1c < 7%. There were also significant (P < 0.001 in all instances) reductions in fasting plasma glucose (3.0 mmol/L), plasma glucose 2 hours after breakfast (4.8 mmoL/L), body weight (1.9 kg), body mass index (0.8 kg/m2), systolic blood pressure (BP) (10 mmHg), diastolic BP (7 mmHg), insulin dose (3 U), serum creatinine (0.06 mg/dL), total cholesterol (18 mg/dL), low-density lipoprotein cholesterol (13 mg/dL), high-density lipoprotein cholesterol (1 mg/dL), and triglyceride (42 mg/dL) and an increase in estimated glomerular filtration rate (4.2 mL/min/1.73 m2) from the baseline values. 6.62% experienced adverse events (lightheadedness 2.21%, genital tract infection 0.97%, urinary tract infection 1.24%, generalized weakness 0.48%, and nocturia 0.48%). 1.1% of subjects experienced hypoglycemia, and other 0.12% reported severe hypoglycemic events. Conclusion: Empagliflozin is effective, safe, and tolerable for treating Bangladeshi patients with uncontrolled T2DM as add-on therapy in routine clinical practice with favorable effects on body weight, BP, lipid profile, and renal function.

Background Dementia is a critical late-life health issue that occurs among members of aging societies. This study examined the relationships between eating out, dietary diversity, and mild cognitive impairment (MCI) among community-dwelling older adults. Methods We analyzed data from 597 older adults (median age 73.0 years, interquartile range 69.0–78.0 years; 62.6% females). We applied the food frequency score to evaluate diet variety and the weekly consumption frequencies of ten food items were determined. The National Center for Geriatrics and Gerontology Functional Assessment Tool (NCGG-FAT) was used to evaluate MCI. Finally, we asked the participants how often they ate out each month; those who replied "none" were categorized into the "non-eating out" group. Results The overall prevalence of MCI was 122 (20.4%), with a higher prevalence in the low dietary diversity group than in the high dietary diversity group (28.6% vs. 18.6%). After adjusting for covariates, the participants who self-described as not eating out were independently associated with low dietary diversity (odds ratio [OR]=1.97, 95% confidence interval [CI] 1.20–3.20), while low dietary diversity was associated with MCI (OR=1.72; 95% CI 1.02–2.87). Structural equation models revealed that not eating out had no direct effect on MCI but was associated with MCI via low dietary diversity (root mean square error of approximation=0.030, goodness-of-fit index=0.999, and adjusted goodness-of-fit index=0.984). Conclusions Although non-eating out may not have a direct effect on MCI, an indirect relationship may exist between eating-out habits and MCI via dietary diversity status.

Background Physical inactivity is a risk factor for locomotive syndromes and functional limitations in middle-aged and older adults. Therefore, strategies to promote physical activity should be considered. This study investigated whether users of physical activity monitors were more physically active and exhibited a lower risk of locomotive syndrome, compared with non-users. Methods We analyzed data from 742 Japanese adults aged 60–79 years. The participants were surveyed for their use of physical activity monitors in their daily lives. We also assessed the prevalence of locomotive syndrome. Results We observed significantly higher physical activity levels in users compared with non-users. Moreover, the use of a physical activity monitor was significantly associated with decreased odds of locomotive syndrome (adjusted odds ratio [aOR]=0.48). Significantly lower risk of locomotive syndrome were observed in individuals who had used a monitor for >2 years (aOR=0.42) or had set a personal step goal (aOR=0.32). Conclusion Physical activity monitoring may increase engagement in physical activity-associated behavior. Therefore, monitoring could serve as a useful tool to promote physical health in middle-aged and older adults.

ABSTRACT Multi-drug resistance (MDR) in Shigella continues to pose a significant public health challenge, particularly in developing countries. Recent advances in genomics strengthen the surveillance of MDR-pathogens and antimicrobial resistance (AMR) mediators. However, genome-based investigations into resistome dynamics in Shigella are limited, specifically in Bangladesh. Therefore, we investigated MDR-Shigella resistomes to evaluate their AMR transmission and phylodynamics. Clinical Shigella strains were screened for MDR phenotypes through susceptibility tests against 28 antibiotics from 10 different classes. Whole-genome sequencing (WGS) and bioinformatics approaches were performed to unveil the resistome dynamics: >500 global plasmid entities and >1,000 plasmid-mediated resistance gene clusters from global databases were included in this study. We identified 28 distinct antimicrobial resistance genes (ARGs) from nine antibiotic classes, with 75% originating from plasmids. Notably, two conjugative MDR plasmids included nearly all potential ARGs, conferring resistance to first-line drugs for shigellosis. Two third-generation cephalosporin-resistant [wubC-blaCTX-M-15-ISEcp1 and blaTEM-1] and two macrolide-resistant mobile genomic islands (GIs) [mphA-mrx-mph(R)A-IS6100 and mphE-msrE-IS482-IS6] had emerged in Shigella in Bangladesh. In addition, trimethoprim-aminoglycoside-streptothricin-sulfonamide-resistant dfrA1-sat1-aadA1 and aph3-dfrA14-aph6-sul2 were in conjugative plasmids in Bangladesh. The MDR plasmids and resistant GIs were phylogenetically relevant to Europe, USA, or China-derived isolates, indicating carry-over of the emerging ARGs from heavily industrialized countries and MSM-burdened (men who have sex with men) populations. The global burden of resistance GIs has increased sharply, especially after 2014. Emerging resistance mediators were most frequent (>80%) in human-associated Escherichia coli and Klebsiella pneumoniae. We infer ARGs horizontally propagate among Enteropathogens: informing treatment strategies and supporting policymakers in strengthening AMR-containment efforts utilizing the phylodynamics network.IMPORTANCEThe world is suffering from a high burden of MDR enteropathogens. Healthcare providers in low- and middle-income countries (LMICs) often face trouble finding effective drugs among the many antibiotics introduced in diarrheal treatment. Resistance-mediated drug inactivation is more rapid than the advent of new antimicrobials, leaving enteritis treatment on the edge. In Bangladesh, where one-third of users are self-prescribing antibiotics and thousands are dying due to resistance-related treatment failure, phylogenomic evidence of AMR transmission root is scarce. Therefore, investigating the resistomes of MDR-Shigella, the leading cause of diarrheal deaths in Bangladesh, is crucial. We identified several emerging resistance mediators and their phylogenetic links to global entities, which is significant for improving shigellosis treatment and enhancing AMR containment strategies. Understanding the MDR mechanism in Shigella will help physicians choose effective drugs and anticipate resistance-mediated changes in treatment approaches; the spatiotemporal phylodynamics of AMR mediators aid policymakers in setting effective checkpoints in the AMR transmission network.

IntroductionAging-related deficits in the physiological properties of skeletal muscles limit the control of dynamic stability during walking. However, the specific causal relationships between these factors remain unclear. This study evaluated the effects of aging-related deficits in muscle properties on dynamic stability during walking.MethodsWalking movements were simulated using two-dimensional musculoskeletal models consisting of 18 Hill-type muscles. To assess the effects of aging-related deficits in muscle function on dynamic stability during walking, five models with different muscle properties were created, namely young adult (YA) and older adult (OA) models, models with reduced maximum isometric muscle force, reduced maximum muscle contraction velocity, and prolonged muscle deactivation time (∆F, ∆V, and ∆T models, respectively). The margin of stability (MoS) was used as a measure of dynamic stability during walking.Results and DiscussionThe MoS value of the OA model was greater than that of the YA model, and the ∆F model yielded a larger MoS value than those of the ∆V and ∆T models. Therefore, the OA model achieved a more dynamically stable state than the YA model and the ∆F model required a more stable state to sustain continuous walking compared to the ∆V and ∆T models. These findings indicate that aging-related deficits in muscle function limit the control of dynamic stability during walking with the degeneration of maximum isometric muscle force being the most influential factor. These findings could aid in the development of an intervention program to reduce the risk of falls in older adults effectively.

Background Pain is a serious manifestation in both the acute and chronic stages of Guillain-Barre syndrome (GBS). We evaluated the frequency, characteristics and associated factors of pain and its impact on quality of life (QoL) among patients with GBS.Methods We enrolled 644 patients with GBS from prospective cohort studies in Bangladesh conducted between 2010 and 2024. Data were collected at enrolment and at standard follow-up time points up to 26 weeks. Pain intensity was measured by a pain numeric rating scale. Group differences were tested using the χ² or Fisher’s exact test, longitudinal changes were analysed with repeated-measures analysis of variance and correlations were analysed with Spearman’s rank test.Results The median age of the patients was 31 years, with 70% men. During enrolment, 71% of patients reported pain, which persisted among 38% at week 13 and 26% at week 26. Pain was significantly associated with disease severity, muscle weakness and treatment with intravenous immunoglobulin in both the acute and chronic stages. Patients with acute pain had a higher proportion of axonal GBS (p=0.000) than those without pain. Chronic pain was associated with higher age (p=0.006), male sex (p=0.000), preceding diarrhoea (p=0.033) and dysautonomia (p=0.000). Higher pain intensity was reported among women (p=0.027), patients with higher age (p=0.029) and severe form of GBS (p=0.038) compared with counter groups. Acute pain was significantly associated with the ‘self-care’ (p=0.023), ‘usual activities’ (p=0.049) and ‘anxiety/depression’ (p=0.048) domains of QoL, whereas chronic pain was associated with the ‘anxiety/depression’ (p=0.005) domain.Conclusions Pain presented as a serious symptom negatively affecting the QoL in GBS. Systematic evaluation of pain is recommended to ensure a personalised treatment approach for GBS.

In this study, a kerosene-fueled premixed burner system with a thick and large pore-sized (“coarse”) porous matrix was developed to achieve less-soot stable premixed combustion with variable combustion loads, i.e., turn-down ratio, TDR, defined as the ratio between the maximum and minimum loads. The present burner system mainly consists of the thick and coarse porous matrix made by packed ceramic balls of 8 mm-diameter, which acts as a vaporizer, mixer, and flame holder. The liquid fuel is fed into the porous matrix along with air. As the air and vaporized fuel are supplied toward the top-end (surface) of the porous matrix, a premixed flame is formed at this surface. Benefits of the adopted porous matrix include reduced wettability of the liquid fuel to pores of the porous matrix, which prevents its direct supply to the flame, promotes vaporization and mixing, and functions as a flame holder, allowing the flame to be sustained within the porous matrix. Combustion experiments were then carried out under various equivalence ratios (φ) between 0.47 and 1.34, and temperature measurement was conducted to evaluate the vaporization capability within the porous matrix. The experimental results confirmed that the quasi-steady and stable premixed combustion across the entire surface of the porous matrix throughout the burning event was successfully achieved under all φ values considered in this study. A simplified (one-dimensional) analytical model was developed to examine achievable range of TDR. It was found that the expected achievable TDR was higher than the value for the conventional spray combustion technology (∼ 6). Thus, the present burner system with a thick and coarse porous matrix was effective for attaining stable premixed combustion and a high TDR.

To help achieve a sustainable society, power generation from variable renewable energy (VRE) is increasing even though a stable power supply cannot be ensured because of its intermittent nature. To supply power on demand, the installation of energy storage systems is essential. This study conducts a life cycle assessment of an energy storage system with batteries, hydrogen storage, or thermal energy storage to select the appropriate storage system. To compare storage systems for connecting large-scale wind energy to the grid, we constructed a model of the energy storage system and simulated the annual energy flow. We calculated the amount of power based on the wind and energy storage installation amounts and evaluated greenhouse gas (GHG) emissions and abiotic resource depletion. The smallest GHG emissions and abiotic resource depletion varied depending on the type and amount of energy storage. Improvements in technology that can store energy based on the intermittency of VRE and energy storage operation could enhance the performance of the energy storage system. A quantitative evaluation of the energy supply capacity and the environmental impacts of the energy storage system while considering regional energy supply can contribute to determining the installation conditions of VRE and energy storage systems.

This study investigated whether a standard calorie diet that is high in glucose and deficient in dietary fibre (described as HGD [high glucose diet]) induces hepatic fat accumulation in mice. We evaluated hepatic steatosis at 7 days and 14 days after the commencement of the HGD. Hepatic triglycerides and areas of oil droplets increased in the HGD group both at day 7 and day 14, whereas weight gain, weight of epididymal fat, and plasma levels of triglycerides were unaffected by HGD consumption. A microarray analysis of the livers revealed that the expression of lipogenesis-related genes was the most affected by HGD consumption. Furthermore, HGD consumption induced the expression of hepatic proteins of fatty acid synthetase, acetyl-CoA carboxylase alpha, and stearoyl-CoA desaturase 1, which are known to be involved in the synthesis of triglyceride. These results indicate that HGD consumption causes fat accumulation in the liver, with an increase in enzymes that are involved in de novo lipogenesis without an accompanying weight or obesity phenotype. Our new findings suggest that HGD consumption could serve as a breeding ground for liver steatosis.
