Prevalence of Helicobacter pylori infection in China from 2014-2023: A systematic review and meta-analysis

BACKGROUND Helicobacter pylori (H. pylori) stands as the predominant infectious agent linked to the onset of gastritis, peptic ulcer diseases, and gastric cancer (GC). Identified as the exclusive bacterial factor associated with the onset of GC, it is classified as a group 1 carcinogen by the World Health Organization. The elimination of H. pylori plays a crucial role in the primary prevention of GC. While the prevalence has declined in recent decades, H. pylori infection is still highly prevalent in China, accounting for a significant part of the disease burden of GC. Therefore, updated prevalence information for H. pylori infection, especially regional and demographic variations in China, is an important basis for the design of targeted strategies that will be effective for the prevention of GC and application of policies for H. pylori control. AIM To methodically evaluate the occurrence of H. pylori infection throughout China and establish a reference point for subsequent investigations. METHODS A systematic review and meta-analysis was conducted following established guidelines, as detailed in our methodology section. RESULTS Our review synthesized data from 152 studies, covering a sample of 763827 individuals, 314423 of whom were infected with H. pylori . We evaluated infection rates in mainland China and the combined prevalence of H. pylori was 42.8% (95%CI: 40.7-44.9). Subgroup analysis indicated the highest prevalence in Northwest China at 51.3% (95%CI: 45.6-56.9), and in Qinghai Province, the prevalence reached 60.2% (95%CI: 46.5-73.9). The urea breath test, which recorded the highest infection rate, showed a prevalence of 43.7% (95%CI: 41.4-46.0). No notable differences in infection rates were observed between genders. Notably, the prevalence among the elderly was significantly higher at 44.5% (95%CI: 41.9-47.1), compared to children, who showed a prevalence of 27.5% (95%CI: 19.58-34.7). CONCLUSION Between 2014 and 2023, the prevalence of H. pylori infection in China decreased to 42.8%, down from the previous decade. However, the infection rates vary considerably across different geographical areas, among various populations, and by detection methods employed.

Feasibility of Peroral Cholangioscopy in the Initial Endoscopic Retrograde Cholangiopancreatography for Malignant Biliary Strictures

Background: Peroral cholangioscopy (POCS) is valuable for assessing malignant biliary strictures; however, biliary drainage prior to POCS often hinders accurate diagnosis. Objectives: This retrospective study aimed to investigate the feasibility of POCS using a newly developed cholangioscope, CHF-B290, during initial endoscopic retrograde cholangiopancreatography (ERCP) for malignant biliary strictures. Methods: This multicenter retrospective study included patients who underwent initial ERCP for malignant biliary strictures at two institutions between January 2018 and March 2022. Patients who underwent initial ERCP with POCS were classified into the POCS group, and those without POCS were classified into the non-POCS group. To prevent post-POCS cholangitis, the original irrigation system for CHF-B290 was used in all POCS examinations. The primary endpoint was the rate of post-ERCP biliary infections, and the secondary endpoints were other ERCP-related complications, including pancreatitis, bleeding, and perforation. Results: Overall, 53 and 94 patients were included in the POCS and non-POCS groups, respectively. For the primary endpoint, the rate of post-ERCP biliary infection was not significantly different between the two groups (1.9% vs. 5.3%, p = 0.42). For the secondary endpoints, no significant differences were observed in the rates of post-ERCP pancreatitis (5.7% vs. 6.4%, p = 1.00) and other ERCP-related complications. The overall complication rate was 9.4% in the POCS group and 13% in the non-POCS group (p = 0.60). Conclusions: POCS during the initial ERCP for malignant biliary strictures is feasible.

Application of Submandibular Intubation as Alternative to Elective Short-Term Tracheotomy for Particular Cases of Oral and Maxillofacial Tumors Resection and Defects Reconstruction

Objective: To describe the cases of oral and maxillofacial tumors (OMFT) resection and defects reconstruction under submandibular intubation (SMI) performed in our institution; secondly, to systematically review and analyze the characteristics of studies about SMI in oral and maxillofacial surgery to estimate the incidence rate of complication. Method: Data related to all 6 patients included in this study were prospectively collected from November 2016 to November 2023. The tract for endotracheal tube was created by bluntly dissection from the submandibular area to the floor of mouth. We performed an exhaustive search for studies about SMI using Pubmed, Embase, Proquest, and Chinese Biomedical Literature Database. Meta-analysis of the incidence rate of complication and infection was performed using STATA 14.1. Results: There was a male predominance (87.3%); the mean age was 47.8±16.8 years; squamous cell carcinoma (SCC) was the most frequent diagnosis (33.3%); the mean time of the operation was 237.0±65.2 minutes; the SMI procedure mean time was 5.5±0.9 minutes; and the mean time to extubation 133.3±12.5 minutes. No accident or complication was observed intraoperatively and postoperatively. The systematic review included 22 out of 234 studies screened. The meta-analysis showed an overall complication rate and superficial infection rate of 5.7% and 3.7% in the last 15 years versus 20.2% and 10.6% in over 15 years ago. Conclusion: Submandibular intubation was found technically easy, safe, and effective alternative of elective short-term tracheotomy, orotracheal and nasotracheal intubations in our series of OMFT resection and defects reconstruction.

Self-poisoning in young Australians: The impact of COVID-19 and recent trends following easing of restrictions

Introduction: Self-poisoning is the most common form of hospitalised self-harm in young people and has been increasing over the last decade. The COVID-19 pandemic was associated with further increases in self-harm in adolescents. There are limited data on changes after pandemic restrictions ended. This study aimed to describe recent trends in self-poisoning in young people. Setting: Australia 2018–2023. Methods: A retrospective analysis of self-poisoning calls to Australia’s poisons information centres. Intentional poisoning exposures in people aged 5–19 years were included in the main analysis. We also examined intentional poisonings in people aged 20 and over for comparison. We used interrupted time-series analysis to estimate the impact of COVID-19 (March 2020) and ‘re-opening’ (December 2021), when many restrictions were lifted in Australia. We compared effects in the jurisdictions with most disruptions and lockdowns with other jurisdictions. Results: There were 201,755 self-poisonings documented, 64% female, with 19,946 children (aged 5–14, 9.9%) and 44,388 adolescents (aged 15–19, 22.0%). There was a steep increase in the rate of poisoning in female children and adolescents – with the annual increase being 1.361 (95% confidence interval = [1.074, 1.735]) and 1.154 (95% confidence interval = [1.049, 1.283]) times faster than pre-pandemic trends in these two groups between March 2020 and December 2021. Following relaxation of restrictions, there was a sudden drop and then slow decline in self-poisonings (despite rising COVID-19 infection rates). There was an overall 29.6% increase in intentional poisonings in young people over the study period. This is markedly more pronounced among young females (37.0%) vs males (11.2%). There were substantial jurisdictional variations, with larger increases in Victoria, Tasmania and the Australian Capital Territory. Conclusion: There has been a marked increase in child and adolescent female self-poisonings over the last 6 years, with increases strongly associated with COVID-19 pandemic restrictions but persisting after their removal.

Implications of Asymptomatic Carriers for Tuberculosis Transmission and Control in Thailand: A Modelling Approach

Tuberculosis (TB) is a regional and global bacterial illness that has been expanding and affecting individuals in every generation. An unknown percentage of asymptomatic hosts have TB, and the infection can spread while exhibiting no symptoms. These asymptomatic TB carriers, who contribute to the spread of the illness yet go mostly undetected, may make it more difficult to prevent transmission. In this study, we utilized the concept of symmetry to construct a manageable disease modelling framework for TB transmission and control. We developed a TB model to investigate the potential influence of asymptomatic carriers, symptomatic infections, and the entirety of TB prevalence on different approaches to treatment and prevention in Thailand. Annual TB incidence data from Thailand from 2000 to 2022 were used to calibrate the model parameters. We assessed the potential for reaching conflicting results about the management and spread of tuberculosis in Thailand. Our results showed that some TB strategies that were thought to be effective in reducing transmission may have the opposite impact, or that an intervention’s effectiveness might be overestimated, making it seem unfeasible in certain scenarios. For example, the objective of TB treatment, which attempts to decrease the occurrence of symptomatic TB infections, is to decrease the TB infection and propagation rates if the relative carrier (η) is less than one. Nonetheless, our results indicate that this strategy may increase the frequency of asymptomatic TB patients, symptomatic TB viral infections, and overall TB prevalence if η has been sufficiently understated. We also found that reducing only the progression rate of symptomatic TB infections cannot stop asymptomatic TB carriers and total TB prevalence, even when the relative infection of carriers (η) is less than unity. Our research provides a better understanding of the role of asymptomatic patients in spreading TB and highlights the need to accurately include bearers in models that guide Thailand’s TB control strategy.

Clinical and Immune Effects of Peri-Transplantation JAK Inhibition for Myelofibrosis.

Despite the introduction of JAK inhibitors, allogeneic hematopoietic cell transplant remains the only potentially curative treatment for patients with myelofibrosis but has considerable treatment-related complications. Whether the incorporation of JAK inhibition into the transplant algorithm leads to improved outcomes is still unclear. Here, we analyzed different transplant platforms in myelofibrosis patients undergoing a first transplant, comparing immune profiles and outcomes of (1) 33 patients continuing JAK inhibition at start of conditioning until stable engraftment (PERI-group), (2) 38 patients receiving JAK inhibition prior to transplant until start of conditioning (PRE-group), and (3) 38 patients that had never received JAK inhibition (NON-group). Patients in the PERI-group showed significantly higher early B-cell recovery as well as significantly increased late recovery of gamma-delta T cells and NK cells. We observed excellent neutrophil and platelet engraftment (100% for both) in the PERI-group and no hematotoxic effects or increased rates of infections following peri-transplant JAK inhibition. Cumulative incidence of acute graft-versus-host disease (GvHD) grade II-IV at day 100 after transplant was 15% in the PERI-group versus 29% in the PRE-group versus 34% in the NON-group. Cumulative incidence of relapse at 1 year after transplant was 9% in the PERI-group compared with 16% in the PRE-group and 18% in the NON-group. In conclusion, peri-transplant JAK inhibition was feasible with promising engraftment and acute GvHD rates, though deserves further investigation.

Laparotomy Versus Laparoscopy Cholecystectomy for Surgical Treatment in Patients with Gallstone Disease: A Comparative Cost-Effectiveness Analysis

Background: Due to the increasing costs of the healthcare system and limited financial resources, healthcare policymakers should adopt more cost-effective strategies. Objectives: This study aimed to compare the cost-effectiveness of laparotomy cholecystectomy with laparoscopy. Methods: This economic evaluation was conducted on patients with cholecystitis who were candidates for surgery in a private hospital in Ahvaz in 2021. Data collection tools consisted of four parts: (1) demographic information checklist; (2) clinical information checklist; (3) cost checklist; and (4) effectiveness assessment tool. SPSS22 and STATA14.2 were used for data analysis. One-way sensitivity analysis and Tornado diagrams were performed using Tree Age software. Results: The mean total effectiveness score in patients treated with laparoscopy was 83.44 (SD = 11.34), which was higher than those treated with laparotomy at 68.39 (SD = 13.61). This difference was statistically significant in all effectiveness criteria, except for postoperative infection rates and length of operation (P < 0.001). The mean cost for patients undergoing laparoscopy was significantly higher than for those undergoing laparotomy ($481.43 vs. $459.49). However, overall, laparoscopic treatment (5.77) was more cost-effective than laparotomy (6.71). The laparoscopic procedure was approximately $1.47 per effectiveness unit cheaper than laparotomy, according to the ICER. One-way sensitivity analysis showed that the laparoscopic method remained more cost-effective, even when adjusting for cost and effectiveness components. Conclusions: Although laparoscopic cholecystectomy was more expensive than laparotomy cholecystectomy, it was generally more cost- effective. The results of this research may assist Iran’s healthcare policymakers and managers in promoting laparoscopic cholecystectomy in hospitals.

Effects of clindamycin and amoxycillin as prophylaxis against early implant failure: double-blinded randomized clinical trial.

The objective of this randomized controlled clinical trial (RCT) was to compare the frequency of early implant failure, postoperative infection, and pain/inflammation and the degree of implant stability between healthy non-penicillin-allergic individuals receiving a single prophylactic dose of 600mg clindamycin versus 2g amoxicillin at 1h before implant surgery. A single-center double-blinded RCT study with parallel groups was undertaken. Eighty-two patients fulfilled study inclusion criteria and were randomly assigned to the amoxicillin (n = 41) or clindamycin (n = 41) group. The primary outcome variable was early implant failure. The presence of infection was evaluated immediately after surgery and on days 7, 14, 30, and 90, and postoperative pain/inflammation was assessed daily on days 1 to 7 post-surgery. Resonance frequency analysis was used to measure primary and secondary implant stability. One early implant failure was observed (1/81), in a patient from the amoxicillin group. No statistically significant between-group differences were observed in early implant failure rate, postoperative infection rate up to 90 days, pain/inflammation scores during the first week post-surgery, or primary or secondary stability values. A single dose of 600mg clindamycin before implant surgery does not increase the risk of early implant failure or infection. These findings suggest that a single dose of 600mg clindamycin at 1h before implant surgery is a safe antibiotic prophylactic approach; however, when a more prolonged antibiotic therapy is required, it appears advisable to prescribe an alternative antibiotic to avoid adverse effects.

Modeling the delay propagation dynamics in high-speed railway networks with a traffic-driven SIS epidemic model

The propagation of delays is a prevalent issue in high-speed railway (HSR) networks. However, the underlying properties of delay propagation have not been fully explored, hindering the effective management of this problem. In this paper, considering the impact of traffic flow, we model the delay propagation as a traffic-driven susceptible–infected–susceptible (SIS) epidemic spreading process. We introduce a traffic frequency matrix to estimate the traffic rate and further derive the propagation dynamic equations using a continuous-time Markov chain method. We then derive the epidemic threshold of the model, which is proportional to the recovery rate and inversely proportional to the average path length. Finally, through simulation, we study the impacts of various factors including the infection rate, recovery rate, and the degree and number of initial delay stations. Our work provides some insights for the prediction and control of delay propagation in HSR networks.

Evaluation of rate and severity of COVID-19 infection after vaccination in the age group of 18–25-year population: A questionnaire-based study

Objectives: Covid-19 has been a challenging and challenging pandemic for mankind, with the introduction of the novel coronavirus, SARSCov-2, in late December 2019. Vaccination has proven to be a boon in these challenging times, with the study aiming to determine the efficacy of vaccination against the novel coronavirus in terms of the number of cases affected before and after vaccination and the severity of illness in post-vaccinated Covid-affected individuals. The study aims to learn from the lessons learned during this challenging period. Material and Methods: Students between age group of 18 to 25, from Nashik District, Maharashtra State, India, were the subject of a questionnaire-based study. Using Google Form, a survey was created. Results: It was found that vaccination has reduced the number of positive Covid 19 cases and we have seen a statistically significant decrease in the number of Covid-19-affected individuals. Conclusion: In the present study, we found that the severity is reduced and a smaller number of severe cases are seen after vaccination however the sample was small so this finding was not statically significant.

Analysis on characteristics and multilocus sequence typing of Clostridium perfringens in western China.

The objective of this study was to identify and analyse the distribution characteristics, toxin genotyping and antimicrobial susceptibility of Clostridium perfringens and to investigate its resistance mechanisms and genetic characteristics. The MICs of various antibiotics against C. perfringens were determined using the agar dilution method, and resistance genes and toxin genotypes were detected by PCR. Genetic relationships were analysed using MLST. WGS was conducted on the DNB system and PacBio platforms. Analysis of 36 strains of C. perfringens revealed that the major toxin types were types C and F, with 86.1% of the strains isolated from bile samples. Of these, 30.6% of the strains exhibited MDR, with resistance rates of 75.0%, 52.8% and 52.8% for penicillin, clindamycin and ampicillin, respectively; however, no resistance to metronidazole and carbapenems was observed. MLST analysis identified 29 STs, including 14 novel types. ST221 and ST498 were the dominant types. The WGS revealed that the most prevalent virulence factors are plc (100.0%), nagH (100.0%), colA (100.0%), nanJ (100.0%), entB (100%), nanH (97.0%), entA (97.0%) and nanI (90.9%). Among these factors, the primary determinants of tetracycline resistance are tetA (66.7%) and tetB (78.8%), which represent the most frequently detected antibiotic resistance genes. This study indicates that the infection rate of C. perfringens is relatively high, with the majority of isolated strains exhibiting MDR. The observed high levels of antibiotic resistance, combined with the significant genetic diversity of these strains, suggest a potential public health risk.

Seroepidemiology of pertussis immunity in five provinces of China: A population-based, cross-sectional study

ABSTRACT This study aimed to evaluate the seroprevalence of Bordetella pertussis and persistence of antibodies following vaccination. We recruited 6060 healthy subjects from five provinces of China during 2017–2018. Serum IgG antibodies against pertussis toxin (anti-PT IgG) and filamentous hemagglutinin (anti-FHA IgG), and serum IgA antibodies against pertussis toxin (anti-PT IgA) were measured by ELISA. Geometric mean concentration (GMC), seropositivity rate, and recent infection rate were calculated. Among 0–6 years-olds, the anti-PT IgG, anti-PT IgA, and anti-FHA IgG GMCs were 6.4 IU/ml (95% CI 6.1–6.8), 2.8 IU/ml (95% CI 2.7–2.8), and 13.3 IU/ml (95% CI 12.4–14.2), respectively. The anti-PT IgG GMC increased in accordance with the primary vaccination series (4–6 months) and the toddler booster (18–24 months), but declined thereafter through to age 5 years [4.7 IU/ml (95% CI 4.2–5.4)]. The seropositivity rate of pertussis in >6 year-olds was 9.0% (95% CI 8.1–9.9) and the recent infection rate was 3.3% (95% CI, 2.7–3.8). Recent infection rate began to increase from 6 years of age, with peaks at 9, 20, 40, and ≥60 years of age. The anti-PT IgG GMCs of children aged 0–6 years who were vaccinated with DTaP, DTaP-IPV//PRP～T, and DTaP-Hib were 5.9 IU/ml (95% CI 5.6–6.3), 20.7 IU/ml (95% CI 15.6–27.8), and 11.7 IU/ml (95% CI 7.5–18.1) (p < .001), respectively (p < .001). Pertussis vaccination improves anti-PT IgG levels, however these wane soon after vaccination. Sero-estimated recent infection rates appear to increase from school age into adolescence and adulthood. Pertussis vaccine boosters should be considered in these age groups.

Molecular Detection of Haemonchus spp Parasite in Human in Babylon Province, Iraq

Stool samples of 100 human were collected the diagnosis of Haemonchus worm in Babylon province usied Microscopic examination by PCR assay. The human were classified into sub-groups according to age, locality and sex in order to study association of these risk factors with rate of infection. The results showed, by using (PCR) based on detection 18srRNA gene to Haemonchus worm human stool samples that the persons was infected with this worm , and the infection rate was (32%) The rate of positive cases, infection was the highest in Western Hamza district and it was (40%), followed Al-Musayyab district was (34.61%), and the rate in Al-Qassim a District was (30%), whereas in Al Mahaweel district it was (20.83%), The present study showed no significant impact of geographical variation. The infection rate of Haemonchus worm for human in age group (41-60) was (43.75%) while in age group (21-40) was (38.46%), in age group (11-20) was (26.66%), and in age group (&lt; 10 years) was (20%), and the statistical analysis reveals that there was no significant (P&gt;0.05) difference in the infection rate of parasite between age intervals. This current study concluded the rate of infected male with Haemonchus worm was (40%) and females was (27.69%) Through the above, we found that the percentage of infection in females was greater than males, when results statistical analyzed showed there are no significant effect in infected rate at (P&gt;0.05) on sex. The study is the first in lraq to diagnosis the presence of Haemonchus worm in human in Iraq.

Comparative analysis of the epidemiological characteristics of adenovirus, rotavirus A, and coinfection in children during 2014-2023 in Guangzhou, China.

Infection is the cause of diarrhoea, and rotaviruses and adenoviruses are important pathogens in children. A retrospective study was conducted on 144,067 children with diarrhoea between 2014 and 2023 in China. We used the colloidal gold method to detect intestinal adenovirus and rotavirus A antigens in faeces. The epidemiological characteristics of these viruses and the impact of meteorological factors on them were analysed before and after coronavirus disease 2019 (COVID-19) pandemic. During this decade, the positive rate of adenovirus infection was 6.41%, while the positive rate of rotavirus A infection was 11.81%, higher than that of adenovirus infection. The positive rate of adenovirus and rotavirus A coinfection was 1.92%. The positive rates of adenovirus, rotavirus A and coinfection showed a fluctuating trend, and suddenly decreased in 2020. There was an apparent decrease of positive rate of rotavirus A, with a decrease of 57.27%, during 2020-2023. Surprisingly, the positive rate of adenovirus infection exceeded that of rotavirus A infection in 2021 and 2023. During the COVID-19 pandemic, the proportion of female patients and children over two years of age infected with adenovirus or rotavirus A increased, while the proportion of cases in winter decreased. In addition, we found that the positive rate of rotavirus A infection was related to average temperature and sunshine, and the positive rate of adenovirus and rotavirus A coinfection was only related to sunshine. However, these correlations disappeared during the COVID-19 pandemic. This study revealed the recent prevalence of adenovirus and rotavirus A infections in children with diarrhoea in south-central China and provided a theoretical basis for the prevention and control of viral diarrhoea.

Effects of Routine Catheterization on Urinary Tract Infection Rates After Minor Gynecologic Surgeries

This pilot study describes urinary tract infection (UTI) rates after routine single catheterization during minor gynecologic surgeries at a tertiary care community hospital. Records from 762 patients from 2021 were reviewed, including procedures such as hysteroscopy, loop electrosurgical excision procedure, and dilation and curettage. Findings revealed a 42.4% catheterization rate, with a significantly higher proportion of catheterized patients having UTIs (5.6%) compared with noncatheterized patients (2.5%). This study suggests that catheterization, unless medically necessary, should be avoided to reduce nosocomial infection risk. These results advocate for reconsidering current practices to enhance patient care and minimize preventable UTIs.

A role of fear on diseased food web model with multiple functional response.

In this paper, we analyze the role of fear in a three-species non-delayed ecological model that examines the interactions among susceptible prey, infectious (diseased) prey, and predators within a food web. The prey population grows in a logistic manner until it achieves a carrying capacity, reflecting common population dynamics in the absence of predators. Diseased prey is assumed to transmit infection to healthful prey by the use of a Holling type II reaction. Predators, alternatively, are modeled to consume their prey using Beddington--DeAngelis and Crowley--Martin response features. This evaluation specializes in ensuring the non-negativity of solutions, practical constraints on population dynamics, and long-term stability of the system. Each biologically possible equilibrium point is tested to understand the environmental stable states. Local stability is assessed through eigenvalue analysis, while global stability of positive equilibria is evaluated by the use of Lyapunov features to determine the overall stability of the model. Furthermore, Hopf bifurcation is explored primarily based on infection rate $\varepsilon$. Numerical simulations are carried out to validate the theoretical effects and offer practical insights into the model behaviour under specific conditions.

Pandemic preparedness of Egyptian community pharmacists and potential facilitators to the successful implementation of a community pharmacy coronavirus disease 2019 referral service: a cross-sectional survey.

The coronavirus disease 2019 (COVID-19) pandemic resulted in an increased need for essential community services including new roles for pharmacists. Globally, community pharmacists are a highly accessible point of contact for referral. To assess the preparedness of and facilitators to community pharmacists referring patients with suspected COVID-19 symptoms for testing. A cross-sectional survey was administered using a structured questionnaire to 1023 pharmacists (one respondent in each pharmacy) in Egypt between 17 and 30 May 2020. Pharmacists who had received pandemic referral training were significantly more familiar with the referral system in comparison to those who had not (n = 180; 17.6% vs. n = 841; 82.4%, P = .014). Case referral was significantly associated with the referrer (n = 161, 15.8%), demographics of region (P = .001), graduation year (P = .035), and gender (P = .015). The vast majority of respondents identified facilitators to referring, namely university-level teaching (n = 984, 96.7%), continuing professional development (n = 958, 94.3%), smartphone app (n = 809, 80.5%) or telephone hotline (n = 933, 91.5%), IT access (n = 861, 84.7%), and managing patients' attitudes through the media in terms of the importance of declaring symptoms to (n = 998, 97.7%) and cooperating with (n = 977, 96.2%) referrers. Pharmacists' lack of preparedness to engage with the referral process and related roles contributing to tracking the national COVID-19 infection rate could be mitigated by the provision of facilitators suggested by respondents. These included improved cooperation from local healthcare authorities, educational interventions, technological solutions, and the use of the media. Demographics associated with pharmacists' attitudes to referral, and hence the reliability and validity of the national infection rate, demand further investigation.

Antimicrobial stewardship implementation in primary and secondary tier hospitals in India: interim findings from a need assessment study using mixed method design.

Anti-microbial stewardship program (AMSP) is practiced only in tertiary hospitals in India, though, the lower tier hospitals remain the first point of contact in patient care. This study was conducted in lower tier hospitals to calculate antibiotic and multiple antibiotic prescription rate (APR, MPR) for common infections and finding existing strength of health system for optimizing antibiotic prescription. We conducted a cross sectional convergent parallel mix-method study in eight lower tier hospitals of three districts of West Bengal, India. Six hundred OPD prescriptions of UTI, ARI, AUFI, ADD were evaluated. Qualitative data collected through in-depth interviews of medical officers/officers in administrative positions, infection control nurses were analyzed using content analysis method. APR was 63.8% in primary tier hospitals and 60.8% in secondary tier hospitals. The MPR was higher in secondary tier hospital (23.8%). Presence of infection control committee, designated nursing staff, initiation of prescription audit, increased monitoring were identified as few facilitators for future implementation of AMSP in lower tier hospitals. The routine infection control activities of lower tier hospitals are currently delinked from AMR containment measures and thus, customized AMSP needs to be established in these hospitals catering two third of the population of India.

Antibiotic consumption patterns in older adults: a comparative study of people 65 years and older in and outside nursing homes, Belgium, 2016 to 2022.

BackgroundInappropriate antimicrobial consumption (AMC) drives the emergence of antimicrobial resistance. Institutionalised, older populations are associated with antimicrobial treatments of longer duration and broader spectrum than recommended, higher rates of multidrug-resistant infections and poorer outcomes for resistant infections. Yet systematic, national monitoring of AMC in nursing home (NH) residents is lacking.AimTo perform a retrospective analysis of antibiotic consumption in Belgian NHs, we compared analogous populations inside and outside NHs. We aimed to provide a blueprint for establishing surveillance of NH AMC, based on national reimbursement data.MethodsThe National Institute for Health and Disability Insurance supplied reimbursement AMC data for outpatients from 2016 to 2022. Data were classified by the Anatomical Therapeutic Chemical system, expressed as defined daily doses (DDD) and aggregated by prescription month, patient age, sex and residency inside/outside a NH. The number of ensured beneficiaries, aggregated by the same demographic variables, was collected from the Intermutualistic Agency. We compared the DDDs per 1,000 beneficiaries per day, along with secondary metrics for national and international targets for analogous populations inside and outside NHs.ResultsTotal antibiotic consumption decreased in both populations but remained twofold higher in NH residents. Proxy prescription quality metrics were consistently less favourable within NHs and diverged further during the COVID-19 pandemic. Distinct consumption patterns and greater seasonal fluctuations were observed in NH residents.ConclusionGiven the different infection risks and higher antibiotic consumption of NH residents, AMC surveillance and antimicrobial stewardship efforts targeting this fragile population are needed.

Survey of Citizens' Preferences for Combined Contact Tracing App Features During a Pandemic: Conjoint Analysis.

During the COVID-19 pandemic, an increased need for novel solutions such as digital contact tracing apps to mitigate virus spread became apparent. These apps have the potential to enhance public health initiatives through timely contact tracing and infection rate reduction. However, public and academic scrutiny has emerged around the adoption and use of these apps due to privacy concerns. This study aims to investigate public attitudes and preferences for contact tracing apps, specifically in Japan, using conjoint analysis to examine what specifications the public values most in such apps. By offering a nuanced understanding of the values that citizens prioritize, this study can help balance public health benefits and data privacy standards when designing contact tracing apps and serve as reference data for discussions on legal development and social consensus formation in the future. A cross-sectional, web-based questionnaire survey was conducted to determine how various factors related to the development and integration of infectious disease apps affect the public's intention to use such apps. Individuals were recruited anonymously by a survey company. All respondents were asked to indicate their preferences for a combination of basic attributes and infectious disease app features for conjoint analysis. The respondents were randomly divided into 2 groups: one responded to a scenario where the government was assumed to be the entity dealing with infectious disease apps (ie, the government cluster), and the other responded to a scenario where a commercial company was assumed to be this entity (ie, the business cluster). Samples of 500 respondents from each randomly selected group were used as target data. For the government cluster, the most important attribute in scenario A was distributor rights (42.557), followed by public benefits (29.458), personal health benefits (22.725), and profit sharing (5.260). For the business cluster, the most important attribute was distributor rights (45.870), followed by public benefits (32.896), personal health benefits (13.994), and profit sharing (7.240). Hence, personal health benefits tend to be more important in encouraging active app use than personal financial benefits.
