Composição da microbiota intestinal durante a gestação e puerpério em mulheres com diferentes intensidades de sintomas depressivos / Composition of Gut Microbiota During Pregnancy and Postpartum in Women with Varying Degrees of Depressive Symptoms

Os sintomas depressivos durante a gravidez e o período pós-parto (PP) são prevalentes e podem ter implicações profundas para o bem-estar materno e infantil. Evidências emergentes sugerem que a microbiota intestinal pode desempenhar um papel na regulação do humor. Este estudo explora a relação entre a composição da microbiota intestinal e os sintomas depressivos em mulheres grávidas e no pós-parto com diferentes intensidade de sintomas. Foram recrutadas gestantes que faziam acompanhamento nos hospitais HCFMUSP e HU- USP. A partir do preenchimento do questionário de Escala de Edimburgo as participantes foram triadas para os grupos de sintomas ausentes ou leves (AL) e sintomas graves ou moderados (MG). Para a análise de microbiota, as participantes forneceram amostras de fezes em três momentos diferentes. Uma no terceiro trimestre de gestação (G) e duas no período pós-parto. A primeira amostra deste período foi coletada durante a internação do pós-parto (P1), e a segunda durante a consulta de retorno um mês após o parto (P2). A composição da microbiota intestinal foi analisada usando técnicas de sequenciamento de alto rendimento e os ácidos graxos de cadeia curta (AGCC) foram quantificados por cromatografia gasosa acoplada à espectrometria de massas (GC-MS). Análises bioinformáticas e estatísticas foram realizadas utilizando os softwares QIIME 2 (2022.2) e R (4.3.1) para identificar possíveis associações entre a composição da microbiota intestinal e a gravidade dos sintomas depressivos. Os resultados indicam que a familia Enterobacteriacea aparece com maior abundância nas mulheres do grupo MG, especialmente durante o período P1 (p<0,05) e que há uma diminuição significativa (p<0,05) de sintomas depressivos nas participantes do grupo MG desde sua triagem até o fim do acompanhamento do estudo, indicando que conduta terapêutica está sendo eficaz. Apesar de não ter sido estabelecida diferença estatística na abundância relativa da microbiota entre os grupos durante a gestação e nos índices de alfa e beta diversidade entre grupos e entre os períodos, é possivel observar uma tendência de mudança de microbiota ao longo do tratamento com aumento do gênero Bifidobacterium, diminuição da familia Enterobacteraceae e é possivel observar uma aparente correlação inversa entre a diminuição da intensidade de sintomas depressivos e o aumento da abundância dos gêneros Bifidobacterium e Clostridium, além do aumento das concentrações de AGCC. Em conclusão, a composição da microbiota intestinal parece ser influenciada pela gravidade dos sintomas depressivos em mulheres grávidas e no pós-parto. Pesquisas adicionais são necessárias para explorar a relação entre a microbiota intestinal e a depressão perinatal e determinar as implicações clínicas dessas descobertas para a saúde materna e infantil.

Depressive symptoms during pregnancy and the postpartum period (PP) are prevalent and can have profound implications for maternal and infant well-being. Emerging evidence suggests that the gut microbiota may play a role in mood regulation. This study explores the relationship between gut microbiota composition and depressive symptoms in pregnant and postpartum women with different symptom severities. A cohort of pregnant women were recruited from HCFMUSP and HU-USP. Participants completed standardized depression assessment tools and were allocate in groups of absent or mild depressive symptoms (AL) and moderate or severe depressive symptoms (MG) and provided stool samples in three different time periods. One at the third gestation trimester (G) and two at the postpartum period. The first sample from this period was collected during postpartum hospitalization(P1), and the second during the onemonth postpartum follow-up appointment (P2). Their gut microbiota composition was analyzed using high-throughput sequencing techniques and Gas chromatography mass spectrometry (GS-MS) for quantification of short-chain fatty acids (SCFAs). Bioinformatic and statistical analyses were performed using softwares QIIME 2 (2022.2) and R (4.3.1) to identify potential associations between gut microbiota composition and depressive symptom severity. Findings that the Enterobacteriaceae family appears more abundantly in women of the MG group, especially during period P1 (p<0.05), and that there is a significant decrease (p<0.05) in depressive symptoms among the participants of the MG group from their screening to the end of the study follow-up, suggesting that the therapeutic approach is effective. Although no statistical differences in alpha and beta diversity indices were established between groups and across periods, it is possible to observe a trend of microbiota change during the treatment, with an increase in the Bifidobacterium genus, a decrease in the Enterobacteriaceae family, and an apparent inverse correlation between the reduction in the intensity of depressive symptoms and the increased abundance of the Bifidobacterium, Clostridium, and Dorea genera, as well as an increase in the concentrations of SCFAs. In conclusion, composition of gut microbiota appears to be influenced by the severity of depressive symptoms in pregnant and postpartum women. Further research is warranted to explore links between gut microbiota and perinatal depression and to determine the clinical implications of these findings for maternal and infant health

A Hospital-based Observational Study of Newly diagnosed Sthula Prameha Subjects with special reference to type 2 Diabetes Mellitus from Maharashtra, India

Abstract The aim of this study is to provide a real picture of the disease burden of Prameha in society. The study was performed in Government Ayurved College and Hospital, Nagpur, Maharashtra during Oct 2015-Mar 2016. Total 60 patients of newly diagnosed type 2 diabetes mellitus attending the Kayachikitsa Opd of GAC Nagpur were included for the study. The subjects details were recorded in case report form. The CRF included many variables such as sociodemographic factors, presenting symptoms, risk factors such as hypertension, obesity and glycaemic status, family history of diabetes and physical activity. Other parameters like BMI, glycosylated haemoglobin, fasting and post prandial blood sugar and fasting lipid profile were documented. Descriptive and bivariate analyses were carried out using the XLSTAT software (2020). Amongst 60 subjects, 65% were male and 93.3% were adults. 78% of subjects were following sedentary lifestyle and 40% had family history of diabetes. The results revealed that, obesity, family history of diabetes, uncontrolled glycemic status, sedentary lifestyles, and hypertension were prevalent among the Prameha subjects. The characterization of this risk profile and early detection of prameha by observing poorvarupa will contribute to designing more effective and specific strategies for screening and controlling Prameha in Maharashtra, India.

Hospital readmission within 30 days of older adults hospitalized in a public hospital

Older adults have difficulty monitoring their drug therapy in the first thirty days following hospital discharge. This transition care period may trigger hospital readmissions. The study aims to identify the factors associated with the readmission of older adults 30 days after discharge from the perspective of drug therapy. This is a cross-sectional study and hospital admission within 30 days was defined as readmission to any hospital 30 days after discharge. The complexity of the drug therapy was established by the Medication Regimen Complexity Index (MRCI).. Readmission risks were predicted by the "Readmission Risk Score - RRS". The multivariate logistic regression was used to identify factors associated with readmission within 30 days after discharge. Two hundred fifty-five older adults were included in the study, of which 32 (12.5%) had non-elective hospital readmission. A higher number of readmissions was observed with increased RRS value, suggesting a linear gradient effect. The variables included in the final logistic regression model were the diagnosis of cancer (OR=2.9, p=0.031), pneumonia (OR=2.3, p=0.055), and High MRCI (> 16.5) following discharge (OR=1.9, p=0.119). The cancer diagnosis is positively associated with hospital readmissions of older adults within 30 days

Association of reproductive risk factors and comorbidities among molecular subtypes of Breast cancer in a Tertiary care Hospital

The reasons for the recently observed increase in the incidence of breast cancer in the Indian population are not clearly understood, but thought to be largely explained by westernization of lifestyles and changes in reproductive behavior, which characterize exposure to hormones. Our aim is to review the reproductive risk factors and comorbidities and evaluate the association between molecular subtypes of breast cancer. A hospital-based analytical case-control study was conducted among the breast cancer cases with controls in a multispecialty teaching hospital for a period of one year. Totally, 130 subjects were recruited and an interview was conducted using a structured questionnaire to obtain demographic and risk factor data, including tissue marker status (ER, PR and HER-2) obtained from case files. Data were analyzed with SPSS-20 version. Results: The highest age group reported in this study was 51- 60 years which has a 3.8 times increased risk compared to other age and the age group of 31- 40 have a decrease risk of 0.33. In this study, the percentage of post menopause (68%) and mothers not breastfeeding (10%) was higher in cases compared to controls and a noted increase in the risk of breast cancer with odds ratio (OR) of 2.745 (p= <0.0001) and 9.08 (p=0.01) respectively. Duration of breastfeeding showed significantly (p=<0.0001)) moderate positive correlation (r=0.549, 0.457, 0.418 and 0.636) for luminal A, luminal B, HER+, and triple negative respectively. This study found that all the reproductive risk factors do not have correlation with a molecular subtype of breast cancer except breastfeeding. Post menopause and breastfeeding were common factors associated with all people and could be modifiable to prevent the occurrence of breast cancer through lifestyle change

Off-label drug use in an adult intensive care unit of a Brazilian hospital

Abstract The objective of this study was to determine the prevalence and describe the factors associated with off-label drug use in an adult intensive care unit (ICU) of a Brazilian hospital. An analytical, cross-sectional, prospective study was conducted in the adult ICU population from March 2018 to May 2018. Off-label use of medication was classified by indication, dosage, route of administration, type and volume of diluent, and duration of administration. Most patients were female (57.89%), non-elderly (56.14%), and had a mean age of 54.44 ± 17.15 years. The prevalence of off-label drug use was 70.31%, but was not associated with the clinical severity of the patients. A statistically significant association was observed between label use of drugs and prescribing potentially inappropriate medicines (PIM). The most common reasons for off-label drug use were therapeutic indication (19.58%) and volume of diluent (23.30%). Drug administration by enteral tubes accounted for the largest number of off-label uses due to route of administration (90.85%). There was a higher prevalence of off-label use of systemic antimicrobials (14.44%) and norepinephrine (9.28%). Our study provided a broad characterization of off-label drug use in an adult ICU and showed why it is important for health professionals to evaluate the specific risks and benefits of this practice

Association between disease activity and quality of life among patients with rheumatoid arthritis

Abstract The aim of this study is the association between the scores of disease activity, functional capacity and quality of life among patients diagnosed with rheumatoid arthritis, under clinical treatment at the Regional University Hospital of Campos Gerais - Wallace Thadeu de Mello and Silva. The sample was composed by volunteer patients, who freely underwent 3 research questionnaires. With the results of the survey, the disease activity score was correlated to the functional capacity and the quality-of-life scores. A mean of 3.87 and 1.2 was observed for the disease activity and the functional capacity scores, respectively, yet not achieving a correlation between those two variables. A strong correlation between the disease activity and the "functional capacity", "general health status" and "mental health" domains was found. The lowest average observed corresponded to "physical limitation", from the quality-of-life questionnaire. There was no statistically significant correlation between disease activity and functional capacity, although disease activity seems to affect the mental health, general health status and functional capacity of patients.

Development and characterization of PLGA-Bupivacaine and PLGA-S75: R25 Bupivacaine (Novabupi®) biodegradable implants for postoperative pain

Abstract In the hospital environment, postoperative pain is a common occurrence that impairs patient recovery and rehabilitation and lengthens hospitalization time. Racemic bupivacaine hydrochloride (CBV) and Novabupi® (NBV) (S (-) 75% R (+) 25% bupivacaine hydrochloride) are two examples of local anesthetics used in pain management, the latter being an alternative with less deleterious effects. In the present study, biodegradable implants were developed using Poly(L-lactide-co-glycolide) through a hot molding technique, evaluating their physicochemical properties and their in vitro drug release. Different proportions of drugs and polymer were tested, and the proportion of 25%:75% was the most stable for molding the implants. Thermal and spectrometric analyses were performed, and they revealed no unwanted chemical interactions between drugs and polymer. They also confirmed that heating and freeze-drying used for manufacturing did not interfere with stability. The in vitro release results revealed drugs sustained release, reaching 64% for NBV-PLGA and 52% for CBV-PLGA up to 30 days. The drug release mechanism was confirmed by microscopy, which involved pores formation and polymeric erosion, visualized in the first 72 h of the in vitro release test. These findings suggest that the developed implants are interesting alternatives to control postoperative pain efficiently.

Incidence of Medication Errors in King Fahad Hospital Madina Saudi Arabia

Abstract This study aimed to evaluate the incidence of medication errors over a period of one year in King Fahad Hospital Madina Saudi Arabia. This retrospective, cross-sectional study was conducted over a period of one year from 2018 January to 2018 December using patient's records. King Fahad Hospital in Madina was selected for the study center. Data collected include the number and types of errors, severity, location of errors, errors by profession, and errors occurred in the medical wards. Statistical analysis was carried out using statistical package for social science version22. A total of twenty- six hundred and fifty-eight medication errors were reported during the study period. Among the reports 2567(96.5%) of the errors were due to near misses, followed by transcribing errors 1597(60%), ordering errors 928(34.9%), duplicative therapy 765(28.7%), wrong dose 454(%). The most common procedures involve medication errors were wrong documentation 442(16.6%), duration 168(6.3%) wrong quantity 162(6.4%). Majority of the medication errors were contributed by physicians (99.2%) and 0.7% of them were due to the pharmacist. In conclusion study findings reported that yet some kind of medication errors has been under reported and it was common in most hospital, further studies with intervention programs needed to control the incidence of medication errors in a Saudi hospital

Beyond the operating room: do hospital characteristics have an impact on surgical site infections after colorectal surgery? A systematic review.

BACKGROUND: Hospital characteristics have been recognized as potential risk factors for surgical site infection for over 20 years. However, most research has focused on patient and procedural risk factors. Understanding how structural and process variables influence infection is vital to identify targets for effective interventions and to optimize healthcare services. The aim of this study was to systematically review the association between hospital characteristics and surgical site infection in colorectal surgery. MAIN BODY: A systematic literature search was conducted using PubMed, Scopus and Web of Science databases until the 31st of May, 2021. The search strategy followed the Participants, Exposure/Intervention, Comparison, Outcomes and Study design. The primary outcome of interest was surgical site infection rate after colorectal surgery. Studies were grouped into nine risk factor typologies: hospital size, ownership affiliation, being an oncological hospital, safety-net burden, hospital volume, surgeon caseload, discharge destination and time since implementation of surveillance. The STROBE statement was used for evaluating the methodological quality. A total of 4703 records were identified, of which 172 were reviewed and 16 were included. Studies were published between 2008 and 2021, and referred to data collected between 1996 and 2016. Surgical site infection incidence ranged from 3.2 to 27.6%. Two out of five studies evaluating hospital size adjusted the analysis to patient and procedure-related risk factors, and showed that larger hospitals were either positively associated or had no association with SSI. Public hospitals did not present significantly different infection rates than private or non-profit ones. Medical school affiliation and higher safety-net burden were associated with higher surgical site infection (crude estimates), while oncological hospitals were associated with higher incidence independently of other variables. Hospital caseload showed mixed results, while surgeon caseload and surveillance time since implementation appear to be associated with fewer infections. CONCLUSIONS: Although there are few studies addressing hospital-level factors on surgical site infection, surgeon experience and the implementation of a surveillance system appear to be associated with better outcomes. For hospitals and services to be efficiently optimized, more studies addressing these variables are needed that take into account the confounding effect of patient case mix.

Trends in Patient Volume by Hospital Type and the Association of These Trends With Time to Cancer Treatment Initiation.

Importance: Increasing demand for cancer care may be outpacing the capacity of hospitals to provide timely treatment, particularly at referral centers such as National Cancer Institute (NCI)-designated and academic centers. Whether the rate of patient volume growth has strained hospital capacity to provide timely treatment is unknown. Objective: To evaluate trends in patient volume by hospital type and the association between a hospital's annual patient volume growth and time to treatment initiation (TTI) for patients with cancer. Design, Setting, and Participants: This retrospective, hospital-level, cross-sectional study used longitudinal data from the National Cancer Database from January 1, 2007, to December 31, 2016. Adult patients older than 40 years who had received a diagnosis of 1 of the 10 most common incident cancers and initiated their treatment at a Commission on Cancer-accredited hospital were included. Data were analyzed between December 19, 2019, and March 27, 2020. Exposures: The mean annual rate of patient volume growth at a hospital. Main Outcomes and Measures: The main outcome was TTI, defined as the number of days between diagnosis and the first cancer treatment. The association between a hospital's mean annual rate of patient volume growth and TTI was assessed using a linear mixed-effects model containing a patient volume × time interaction. The mean annual change in TTI over the study period by hospital type was estimated by including a hospital type × time interaction term. Results: The study sample included 4 218 577 patients (mean [SD] age, 65.0 [11.4] years; 56.6% women) treated at 1351 hospitals. From 2007 to 2016, patient volume increased 40% at NCI centers, 25% at academic centers, and 8% at community hospitals. In 2007, the mean TTI was longer at NCI and academic centers than at community hospitals (NCI: 50 days [95% CI, 48-52 days]; academic: 43 days [95% CI, 42-44 days]; community: 37 days [95% CI, 36-37 days]); however, the mean annual increase in TTI was greater at community hospitals (0.56 days; 95% CI, 0.49-0.62 days) than at NCI centers (-0.73 days; 95% CI, -0.95 to -0.51 days) and academic centers (0.14 days; 95% CI, 0.03-0.26 days). An annual volume growth rate of 100 patients, a level observed at less than 1% of hospitals, was associated with a mean increase in TTI of 0.24 days (95% CI, 0.18-0.29 days). Conclusions and Relevance: In this cross-sectional study, from 2007 to 2016, across the studied cancer types, patients increasingly initiated their cancer treatment at NCI and academic centers. Although increases in patient volume at these centers outpaced that at community hospitals, faster growth was not associated with clinically meaningful treatment delays.

The COVID-19-designated hospitals in China: preparing for public health emergencies.

The designated hospitals are another health approach besides Fangcang shelter hospitals and newly built temporary hospitals for responding to COVID-19 epidemic in China. Faced with the emergency situation, about 1512 hospitals from 363 cities have been designated in China to tackle the spread of COVID-19. They were local hospitals repurposed by the Chinese government as a regional public health response. Their comprehensive services mainly include: "fever-clinics" to screen patients, COVID-19 department for higher-levels of medical care, and makeshift wards for emergencies. As the only COVID-19 designated hospital in Shanghai, we documented three characters (Centralized response and action system, Comprehensive functions, Closed-Loop Management System) and three strategies (Resource allocation, Prevention of nosocomial infection, Management during the post-COVID-19 pandemic stage) from the experience in responding to COVID-19 pandemic. Lastly, learning the lessons from COVID-19 pandemic, a more efficacy and rapid national response to public health emergencies is required. Serving as an essential component of public health system, the COVID-19-designated hospitals should be always prepared for future emergencies.

Time to Surgery for Unstable Thoracolumbar Fractures in Latin America-A Multicentric Study.

OBJECTIVE: We sought to identify delays for surgery to stabilize unstable thoracolumbar fractures and the main reasons for them across Latin America. METHODS: We reviewed the charts of 547 patients with type B or C thoracolumbar fractures from 21 spine centers across 9 Latin American countries. Data were collected on demographics, mechanism of trauma, time between hospital arrival and surgery, type of hospital (public vs. private), fracture classification, spinal level of injury, neurologic status (American Spinal Injury Association impairment scale), number of levels instrumented, and reason for delay between hospital arrival and surgical treatment. RESULTS: The sample included 403 men (73.6%) and 144 women (26.3%), with a mean age of 40.6 years. The main mechanism of trauma was falls (44.4%), followed by car accidents (24.5%). The most frequent pattern of injury was B2 injuries (46.6%), and the most affected level was T12-L1 (42.2%). Neurologic status at admission was 60.5% intact and 22.9% American Spinal Injury Association impairment scale A. The time from admission to surgery was >72 hours in over half the patients and over a week in >25% of them. The most commonly reported reasons for surgical delay were clinical instability (22.9%), lack of operating room availability (22.7%), and lack of hardware for spinal instrumentation (e.g., screws/rods) (18.8%). CONCLUSIONS: Timing for surgery in this sample of unstable fractures was over 72 hours in more than half of the sample and longer than a week in about a quarter. The main reasons for this delay were clinical instability and lack of economic resources. There is an apparent need for increased funding for the treatment of spinal trauma patients in Latin America.

"Swords and Shields" against COVID-19 for patients with cancer at "clean" and "pandemic" hospitals: are we ready for the second wave?

PURPOSE: COVID-19 will continue to disrupt the diagnosis-treatment process of cancer patients. Dr. Abdurrahman Yurtaslan Ankara Oncology Hospital has been considered as a 'non-pandemic' center ('clean') in Ankara, the capital city of Turkey. The other state hospitals that also take care of cancer patients in Ankara were defined as 'pandemic' centers. This study aimed to evaluate hospital admission changes and the precautionary measures in clean and pandemic centers during the pandemic. The effect of these measures and changes on COVID-19 spreading among cancer patients was also evaluated. METHODS: The patients admitted to the medical oncology follow-up, new diagnosis, or chemotherapy (CT) outpatient clinics during the first quarter of pandemic period (March 15-June 1, 2020) of each center were determined and compared with the admissions of the same frame of previous year (March 15-June 1, 2019). COVID-19 PCR test results in clean and pandemic centers were compared with each other. Telemedicine was preffered in the clean hospital to keep on follow-up of the cancer patients as 'noninfected'. RESULTS: In the clean hospital, COVID-19-infected patients that needed to be hospitalized were referred to pandemic hospitals. COVID-19 test positivity rate was eight-fold higher for outpatient clinic admissions in pandemic hospitals (p < 0.001). The number of patients admitted new diagnosis outpatient clinics in both clean and pandemic hospitals decreased significantly during the pandemic compared with the previous year. CONCLUSION: We consider that local strategic modifications and defining 'clean' hospital model during infectious pandemic may contribute to protect and treat cancer patients during pandemic.

Expression analysis of drug-resistant gene (blaOXA-51) in carbapenemases producing Acinetobacter baumannii treated with imipenem/sulbactam combination

Drug-resistant Acinetobacter baumannii is a frightening reality. The aim of this study is to examine the expression profiles of blaOXA-51 gene in carbapenemases producing A. baumannii treated with imipenem/sulbactam combination. Carbapenemases producing A. baumannii was identified among clinical isolates of A. baumannii obtained from patients at Shahid Rajaee hospital, Gachsaran, Iran, from January to June 2018. Synergism testing of imipenem/sulbactam on carbapenemases producing A. baumannii was carried out by broth microdilution method. Eventually, the expression of blaOXA-51 gene was carried out to investigate the inhibitory properties of imipenem/sulbactam combination against carbapenemases producing A. baumannii using quantitative real time RT-PCR. Among A. baumannii isolates, 24% were carbapenemases producing A. baumannii. Imipenem/sulbactam combination revealed synergistic and partial synergistic effect for all tested isolates (FIC= 0.313-0.75). Finally, imipenem/sulbactam combination displayed significant down-regulation of blaOXA-51 gene in carbapenemases producing A. baumannii. Imipenem synergizes with sulbactam against carbapenemases producing A. baumannii by targeting of the blaOXA-51 gene.

Hospitalization Patterns for Inpatient Pediatric Surgery and Procedures in California: 2000-2016.

BACKGROUND: We report hospitalization patterns from 2000 to 2016 for young children (ages 0-5 years old) in California who underwent 1 of the 20 most common inpatient procedures that required general anesthesia and evaluate the estimated probability of treatment at a tertiary care children's hospital (CH) by year. METHODS: We hypothesized that children ≤5 years old increasingly undergo care at tertiary care CHs for common inpatient surgeries or other procedures that require general anesthesia. Data from the California Office of Statewide Health Planning and Development dataset were used to determine procedure, patient age, year of procedure, and hospital name. Hospitals were designated as either tertiary care CHs, children's units within general hospitals (CUGHs), or general hospitals (GHs) based on the California Children's Services Provider List. A tertiary care CH was defined using the California Children's Services definition as a referral hospital that provides comprehensive, multidisciplinary, regionalized pediatric care to children from birth up to 21 years of age with a full range of medical and surgical care for severely ill children. We report the unadjusted percentage of patients treated at each hospital type and, after controlling for patient covariates and comorbidities, the estimated probability of undergoing care at a tertiary care CH from 2000 to 2016. RESULTS: There were 172,318 treatment episodes from 2000 to 2016. The estimated probability of undergoing care at a tertiary care CH increased from 63.4% (95% confidence interval [CI], 62.4%-64.4%) in 2000 to 78.3% (95% CI, 77.3%-79.4%) in 2016. CONCLUSIONS: Children ≤5 years old undergoing common inpatient procedures that require general anesthesia increasingly receive care at tertiary care CHs in California.

Racial Disparities at Mixed-Race and Minority Hospitals: Treatment of African American Males With High-Grade Splenic Injuries.

INTRODUCTION: Racial and socioeconomic disparities in health access and outcomes for many conditions are well known. However, for time-sensitive high-acuity diseases such as traumatic injuries, disparities in access and outcomes should be significantly diminished. Our primary objective was to characterize racial disparities across majority, mixed-race, and minority hospitals for African American (AA) versus white males with high-grade splenic injuries. METHODS: Data from the National Trauma Data Bank was utilized from 2007 to 2015. A total of 24 855 AA or white males with high-grade splenic injuries were included. Multilevel mixed effects regression analysis was used to evaluate disparities in outcomes and resource allocation. RESULTS: Mortality was significantly higher for AA males at mixed-race (odds ratio [OR] 1.6; 95% CI 1.3-2.1; P < .001) and minority (OR 2.1; 95% CI 1.5-3.0; P < .001) hospitals, but not at majority hospitals. At minority hospitals, AA males were significantly less likely to be admitted to the intensive care unit (OR 0.7; 95% CI 0.49-0.97; P = .04) and experienced a significantly longer time to surgery (IRR 1.5; P = .02). Minority hospitals were significantly more likely to have failures from angiographic embolization requiring operative intervention (OR 2.2; P = .009). At both types of nonmajority hospitals, AA males with penetrating injuries were more likely to be managed with angiography (mixed-race hospitals: OR 1.7; P = .046 vs minority hospitals: OR 1.6; P = .08). DISCUSSION: While multiple studies have shown that minority hospitals have increased mortality compared to majority hospitals, this study found this disparity only existed for AAs.

Benchmark performance of laparoscopic left lateral sectionectomy and right hepatectomy in expert centers.

BACKGROUND & AIMS: Herein, we aimed to establish benchmark values - based on a composite indicator of healthcare quality - for the performance of laparoscopic left lateral sectionectomy (LLLS) and laparoscopic right hepatectomy (LRH) using data from expert centers. METHODS: Data from a nationwide multicenter survey including all patients undergoing LLLS and LRH between 2000 and 2017 were analyzed. Textbook outcome (TO) completion was considered in patients fulfilling all 6 of the following characteristics: negative margins, no transfusion, no complication, no prolonged hospital stay, no readmission and no mortality. For each procedure, a cut-off laparoscopic liver resection (LLR) volume by center was associated with TO on multivariable analysis. These cut-offs defined the expert centers. The benchmark values were set at the 75th percentile of median outcomes among these expert centers. RESULTS: Among 4,400 LLRs performed in 29 centers, 855 patients who underwent LLLS and 488 who underwent LRH were identified. The overall incidences of TO after LLLS and LRH were 43.7% and 23.8%, respectively. LLR volume cut-offs of 25 LLR/year (odds ratio [OR] 2.45; bootstrap 95% CI 1.65-3.69; p = 0.001) and 35 LLR/year (OR 2.55; bootstrap 95% CI 1.34-5.63; p = 0.003) were independently associated with completion of TO after LLLS and LRH, respectively. Eight centers for LLLS and 6 centers for LRH, including 516 and 346 patients undergoing LLLS/LRH respectively, reached these cut-offs and were identified as expert centers. After LLLS, benchmark values of severe complication, mortality and TO completion were defined as ≤5.3%, ≤1.2% and ≥46.6%, respectively. After LRH, benchmark values of severe complication, mortality and TO completion were ≤20.4%, ≤2.8% and ≥24.2%, respectively. CONCLUSIONS: This study provides an up-to-date reference on the benchmark performance of LLLS and LRH in expert centers. LAY SUMMARY: In a nationwide French survey of laparoscopic liver resection, expert centers were defined according to the completion of a textbook outcome, which is a composite indicator of healthcare quality. Benchmark values regarding intra-operative details and outcomes were established using data from 516 patients with laparoscopic left lateral sectionectiomy and 346 patients with laparoscopic right hepatectomy from expert centers. These values should be used as a reference point to improve the quality of laparoscopic resections.

Estimating the Net Benefit of Improvements in Hospital Performance: G-Computation With Hierarchical Regression Models.

BACKGROUND: It is important to be able to estimate the anticipated net population benefit if the performance of hospitals is improved to specific standards. OBJECTIVE: The objective of this study was to show how G-computation can be used with random effects logistic regression models to estimate the absolute reduction in the number of adverse events if the performance of some hospitals within a region was improved to meet specific standards. RESEARCH DESIGN: A retrospective cohort study using health care administrative data. SUBJECTS: Patients hospitalized with acute myocardial infarction in the province of Ontario in 2015. RESULTS: Of 18,067 patients hospitalized at 97 hospitals, 1441 (8.0%) died within 30 days of hospital admission. If the performance of the 25% of hospitals with the worst performance had their performance changed to equal that of the 75th percentile of hospital performance, 3.5 deaths within 30 days would be avoided [95% confidence interval (CI): 0.4-26.5]. If the performance of those hospitals whose performance was worse than that of an average hospital had their performance changed to that of an average hospital, 6.0 deaths would be avoided (95% CI: 0.7-47.0). If the performance of the 75% of hospitals with the worst performance had their performance changed to equal that of the 25th percentile of hospital performance, 11.0 deaths would be avoided (95% CI: 1.2-79.0). CONCLUSION: G-computation can be used to estimate the net population reduction in the number of adverse events if the performance of hospitals was improved to specific standards.

Antimicrobial resistance and antibiotic consumption in Mexican hospitals / Resistencia antimicrobiana y consumo de antibióticos en hospitales mexicanos

Abstract: Objective: To establish the current situation of antimicrobial resistance and antibiotic consumption in Mexican hospitals. Materials and methods: Antimicrobial susceptibility data from blood and urine isolates were collected. Defined daily dose (DDD) of antibiotic consumption/100 occupied beds (OBD) was calculated. Results: Study period: 2016 and 2017. Of 4 382 blood isolates, E. coli and K. pneumoniae were most frequently reported, with antimicrobial resistance >30% for most drugs tested, only for carbapenems and amikacin resistance were <20%. A. baumannii had antimicrobial resistance >20% to all drugs. Resistance to oxacillin in S. aureus was 20%. From 12 151 urine isolates, 90% corresponded to E. coli; resistance to ciprofloxacin, cephalosporins and trimethoprim/sulfamethoxazole was >50%, with good susceptibility to nitrofurantoin, amikacin and carbapenems. Global median antimicrobial consumption was 57.2 DDD/100 OB. Conclusions: This report shows a high antimicrobial resistance level in Gram-negative bacilli and provides an insight into the seriousness of the problem of antibiotic consumption.

Resumen: Objetivo: Establecer la situación actual de la resistencia antimicrobiana y el consumo de antibióticos en hospitales mexicanos. Material y métodos:F Se colectaron datos de susceptibilidad antimicrobiana de aislamientos de sangre y orina. Se calculó la dosis diaria definida (DDD) del consumo de antibióticos/100 estancias. Resultados: Periodo de estudio de 2016 a 2017. De 4 382 aislamientos en sangre, E. coli y K. pneumoniae fueron las más frecuentes, con resistencia >30% a la mayoría de las drogas evaluadas; sólo para carbapenémicos y amikacina la resistencia fue <20%. A. baumannii tuvo resistencia >20% a todos los fármacos. La resistencia a oxacilina en S. aureus fue de 20%. De 12 151 aislamientos en urocultivos, 90% correspondió a E. coli; la resistencia a ciprofloxacina, cefalosporinas y trimetoprima/sulfametoxazol fue >50%, con buena susceptibilidad a nitrofurantoína, amikacina y carbapenémicos. La mediana del consumo global de antibióticos en DDD/100 estancias fue de 57.2. Conclusiones: Este reporte muestra el nivel elevado de resistencia en bacilos Gram-negativos y brinda una perspectiva de la gravedad del problema del consumo de antibióticos.
