Association between hospital procedure volume, socioeconomic status, comorbidities, and adverse events related to surgical abortion: A nationwide population-based cohort study.

BACKGROUND: Limited evidence exists on the influence of hospital procedure volume, socioeconomic status, and comorbidities on surgical abortion outcomes. OBJECTIVE: Our study aimed to assess the association between hospital procedure volume, individual and neighborhood deprivation, comorbidities, and abortion-related adverse events. STUDY DESIGN: A nationwide population-based cohort study of all women hospitalized for surgical abortion was conducted from January 1, 2018, to December 31, 2019 in France. Annual hospital procedure volume was categorized into four levels based on spline function visualization: very low (<80), low ([80-300[), high ([300-650[), and very high-volume (≥650) centers. The primary outcome was the occurrence of at least one surgical-related adverse event, including hemorrhage, retained products of conception, genital tract and pelvic infection, transfusion, fistulas and neighboring lesions, local hematoma, failure of abortion, admission to an intensive care unit or death. These events were monitored during the index stay and during a subsequent hospitalization up to 90 days. The secondary outcome encompassed general adverse events not directly linked to surgery. RESULTS: Of the 112,842 hospital stays, 4,951 (4.39%) had surgical-related adverse events and 256 (0.23%) had general adverse events. The multivariate analysis showed a volume-outcome relationship, with lower rates of surgical-related adverse events in very high-volume (2.25%, aOR=0.34, 95%CI [0.29-0.39], p<0.001), high-volume (4.24%, aOR=0.61, 95%CI [0.55-0.69], p<0.001), and low-volume (4.69%, aOR=0.81, 95%CI [0.75-0.88], p<0.001) when compared to very low-volume centers (6.65%). Individual socioeconomic status (aOR=1.69, 95%CI [1.47-1.94], p<0.001), neighborhood deprivation (aOR=1.31, 95% CI [1.22-1.39], p<0.001), and comorbidities (aOR=1.79, 95%CI [1.35-2.38], p<0.001) were associated with surgical-related adverse events. Conversely, the multivariate analysis of general adverse events did not reveal any volume-outcome relationship. CONCLUSION: The presence of a volume-outcome relationship underscores the need for enhanced safety standards in low-volume centers to ensure equity in women's safety during surgical abortions. However, our findings also highlight the complexity of this safety concern which involves multiple other factors including socioeconomic status and comorbidities that policymakers must consider.

Phenotypic Characteristics and Development of a Hospitalization Prediction Risk Score for Outpatients with Diabetes and COVID-19: The DIABCOVID Study.

Diabetes mellitus (DM) has been identified as a risk factor for severe COVID-19. DM is highly prevalent in the general population. Defining strategies to reduce the health care system burden and the late arrival of some patients thus seems crucial. The study aim was to compare phenotypic characteristics between in and outpatients with diabetes and infected by COVID-19, and to build an easy-to-use hospitalization prediction risk score. This was a retrospective observational study. Patients with DM and laboratory- or CT-confirmed COVID-19, who did (n = 185) and did not (n = 159) require hospitalization between 10 March and 10 April 2020, were compared. Data on diabetes duration, treatments, glycemic control, complications, anthropometrics and peripheral oxygen saturation (SpO2) were collected from medical records. Stepwise multivariate logistic regressions and ROC analyses were performed to build the DIAB score, a score using no more than five easy-to-collect clinical parameters predicting the risk of hospitalization. The DIAB score was then validated in two external cohorts (n = 132 and n = 2036). Hospitalized patients were older (68.0 ± 12.6 vs. 55.2 ± 12.6 years, p < 0.001), with more class III obesity (BMI ≥ 40 kg/m2, 9.7 vs. 3.5%, p = 0.03), hypertension (81.6 vs. 44.3%, p < 0.0001), insulin therapy (37% vs. 23.7%, p = 0.009), and lower SpO2 (91.6 vs. 97.3%, p < 0.0001) than outpatients. Type 2 DM (T2D) was found in 94% of all patients, with 10 times more type 1 DM in the outpatient group (11.3 vs. 1.1%, p < 0.0001). A DIAB score > 27 points predicted hospitalization (sensitivity 77.7%, specificity 89.2%, AUC = 0.895), and death within 28 days. Its performance was validated in the two external cohorts. Outpatients with diabetes were found to be younger, with fewer diabetic complications and less severe obesity than inpatients. DIAB score is an easy-to-use score integrating five variables to help clinicians better manage patients with DM and avert the saturation of emergency care units.

The role of neighbourhood socioeconomic status in large for gestational age.

OBJECTIVE: To determine whether neighbourhood socioeconomic status (SES) was associated with large for gestational age (LGA) while considering key sociodemographic and clinical confounding factors. SETTING AND PATIENT: All singleton infants whose parents were living in the city of Marseilles, France, between 2013 and 2016. METHOD: Population-based study based on new-born hospital birth admission charts from the French National Uniform Hospital Discharge Data Set Database. LGA infants were compared to appropriate-for-gestational-age (AGA) infants. Multiple generalized logistic model analysis was used to examine factors associated with LGA. RESULTS: A total of 43,309 singleton infants were included, and 4,747 (11%) were born LGA. LGA infants were more likely to have metabolic and respiratory diseases and to be admitted to the neonatal intensive care unit. Multiparity, advanced maternal age, obesity and diabetes were associated with an increased risk of LGA. Lower neighbourhood SES was associated with LGA (aOR = 1.24, 95% CI: 1.14; 1.36; p<0.0001) independent of age, diabetes, obesity, maternal smoking and multiparity. The strength of this association increased with maternal age, reaching an aOR of 1.50 (95% CI: 1.26; 1.78; p<0.0001) for women > 35 years old. CONCLUSION: Neighbourhood SES could be considered an important factor for clinicians to better identify mothers at risk of having LGA births in addition to well-known risk factors such as maternal diabetes, obesity and age. The intensification of the association between SES and LGA with increasing maternal age suggests that neighbourhood disadvantage may act on LGA cumulatively over time.

[Uro- and nephrotoxic effects of drugs of abuse: Literature review and pharmaco-epidemiological survey in France and in the Marseille area]. / Effets uro-néphrologiques des produits utilisés par les usagers de drogues : revue de la littérature et enquête pharmaco-épidémiologique en France et dans la région de Marseille.

A great diversification of drugs of abuse has been observed in recent years, both in the populations using them and in the types of drugs. Although dependency and psychiatric disorders associated with the abuse of these substances is well known, somatic complications, uro-nephrotoxicity in particular, are less recognized. We propose here an overview of the products used by drugs abusers in France, through the analysis of the national pharmaco-epidemiological study Observation des produits psychotropes illicites ou détournés de leur utilisation médicamenteuse (OPPIDUM). Among the 5003 patients who participated in this survey, 84% were on prescribed psychoactive substances, with indicators of abuse in 28% of cases; more than half of these patients had also been using drugs of abuse (mainly cannabis) in the previous week. We then describe the main urological and renal toxicities of these drugs, in particular of heroin, cocaine, cannabis, ecstasy, LSD, amphetamine, new designer drugs, ketamine and opiate substitution treatment. We finally present a pharmaco-epidemiological survey of patients hospitalized for drugs complications in nephrology at the university hospital of Marseille. Between 2000 and 2015, 22 patients aged 18 to 57 years were hospitalized for renal adverse effects of drugs of abuse, such as glomerulonephritides, focal segmental glomerulosclerosis, acute kidney injury or chronic kidney disease. The somatic complications of drugs participate in their dangerousness and should be a red flag. They should be systematically reported to the addictovigilance national network to allow the improvement of information given to the patients and the medical community, and to adapt the prevention and risk reduction policies.

Emerging role of Raoultella ornithinolytica in human infections: a series of cases and review of the literature.

BACKGROUND: Raoultella ornithinolytica is known to inhabit aquatic environments. The clinical features and outcomes of human infections caused by R. ornithinolytica have been reported for only a limited number of cases. METHODS: A retrospective study of cases of infection caused by R. ornithinolytica managed at four university hospital centres during the period before and after the introduction of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was performed. The aim was to describe the clinical and microbiological characteristics, treatments, and outcomes. RESULTS: Among 187 R. ornithinolytica isolates identified for which clinical information was available, 71 were considered colonizers and 116 were pathogenic. A total of 112 cases of R. ornithinolytica infection were identified. Urinary tract infections, gastrointestinal infections, wound and skin infections, and bacteraemia were observed in 36%, 14%, 13%, and 5% of cases, respectively. Associated infections that have been poorly reported, such as respiratory infections, i.e. pneumonia and pleural effusion, were observed in 24% of cases. Additional diseases reported here for the first time included osteomyelitis, meningitis, cerebral abscess, mediastinitis, pericarditis, conjunctivitis, and otitis. The proportion of R. ornithinolytica isolates resistant to antibiotics was found to be relatively high: 4% of isolates were resistant to ceftriaxone, 6% to quinolones, and 13% to co-trimoxazole. The mortality rate related to infection was 5%. CONCLUSIONS: R. ornithinolytica is an underreported, emerging hospital-acquired infection and is particularly associated with invasive procedures. R. ornithinolytica should never be considered simply a saprophytic bacterium that occasionally contaminates bronchial lavage or other deep respiratory samples or surgical sites. Physicians should be aware of the high rates of antimicrobial resistance of R. ornithinolytica isolates so that immediate broad-spectrum antibiotic treatment can be established before accurate microbiological results are obtained.

Beneficial effects of an intradialytic cycling training program in patients with end-stage kidney disease.

In chronic kidney disease (CKD), oxidative stress (OS) plays a central role in the development of cardiovascular diseases. This pilot program aimed to determine whether an intradialytic aerobic cycling training protocol, by increasing physical fitness, could reduce OS and improve other CKD-related disorders such as altered body composition and lipid profile. Eighteen hemodialysis patients were randomly assigned to either an intradialytic training (cycling: 30 min, 55%-60% peak power, 3 days/week) group (EX; n = 8) or a control group (CON; n = 10) for 3 months. Body composition (from dual-energy X-ray absorptiometry), physical fitness (peak oxygen uptake and the 6-minute walk test (6MWT)), lipid profile (triglycerides (TG), total cholesterol, high-density lipoprotein, and low-density lipoprotein (LDL)), and pro/antioxidant status (15-F2α-isoprostanes (F2-IsoP) and oxidized LDL in plasma; superoxide dismutase, glutathione peroxidase, and reduced/oxidized glutathione in erythrocytes) were determined at baseline and 3 months later. The intradialytic training protocol did not modify body composition but had significant effects on physical fitness, lipid profile, and pro/antioxidant status. Indeed, at 3 months: (i) performance on the 6MWT was increased in EX (+23.4%, p < 0.001) but did not change in CON, (ii) plasma TG were reduced in EX (-23%, p < 0.03) but were not modified in CON, and (iii) plasma F2-IsoP concentrations were lower in EX than in CON (-35.7%, p = 0.02). In conclusion, our results show that 30 min of intradialytic training, 3 times per week for 3 months, are enough to exert beneficial effects on the most sensitive and reliable marker of lipid peroxidation (IsoP) while improving CKD-associated disorders (lipid profile and physical fitness). Intradialytic aerobic cycling training represents a useful and easy strategy to reduce CKD-associated disorders. These results need to be confirmed with a larger randomized study.

The microbial epidemiology of breast implant infections in a regional referral centre for plastic and reconstructive surgery in the south of France.

BACKGROUND: Breast implant infections are usually caused by Staphylococcus aureus and coagulase-negative staphylococci. Gram-negative bacilli are rarely reported to be involved in breast implant infections. METHODS: Thirty-seven cases of microbiologically confirmed breast implant infection managed from January 2008 to June 2012 in the study centre were reviewed, including 10 cases from the study centre itself and 27 cases from private clinics in the region. RESULTS: The prevalence of breast implant infection in the study centre was 0.74% of breast implantation, i.e., 3.23% in breast reconstruction for breast cancer and 0.27% in aesthetic breast augmentation (p=0.0002). Of the 37 cases, 30% had undergone radiotherapy and 11% had undergone a lymph node dissection. S. aureus was identified in 18 cases, Gram-negative bacilli in 10 cases, coagulase-negative staphylococci in eight cases, anaerobic bacteria in eight cases, and streptococci in three cases. Pseudomonas aeruginosa was the second most commonly identified pathogen. Staphylococcus epidermidis was the most frequent coagulase-negative Staphylococcus species. In addition to Propionibacterium acnes and Actinomyces neuii, other facultative and strict anaerobic bacteria have not been reported before, e.g., Bacteroides thetaiotaomicron, Corynebacterium simulans, Dermabacter hominis, Finegoldia magna, and Peptoniphilus harei. Seventy-percent of cases were treated by immediate implant removal. All cases treated only with antibiotics were treated with surgery at the second visit. CONCLUSIONS: The microbiological epidemiology was noted by an increasing the proportion of Gram-negative bacteria and anaerobic bacteria detected with the advent of MALDI-TOF MS and molecular identification for diagnosis.

Decline of semen quality among 10 932 males consulting for couple infertility over a 20-year period in Marseille, France.

Semen from 10 932 male partners of infertile couples was analysed and sperm parameter trends were evaluated at the Reproduction Biology Laboratory of the University Hospital of Marseille (France) between 1988 and 2007. After 3-6 days of abstinence, semen samples were collected. Measurements of seminal fluid volume, pH, sperm concentration, total sperm count, motility and detailed morphology of spermatozoa were performed. Sperm parameters were analysed on the entire population and in men with normal total numeration (≥40 million per ejaculate). The whole population demonstrated declining trends in sperm concentration (1.5% per year), total sperm count (1.6% per year), total motility (0.4% per year), rapid motility (5.5% per year) and normal morphology (2.2% per year). In the group of selected samples with total normal sperm count, the same trends of sperm quality deterioration with time were observed. Our results clearly indicate that the quality of semen decreased in this population over the study period.

Prognostic value of human chorionic gonadotropin changes after methotrexate injection for ectopic pregnancy.

Because early prediction of clinical outcome (one or more injections or surgery) of methotrexate treatment of ectopic pregnancy could ease the intensity of follow-up and patient compliance required, we studied the relationship between the change in hCG levels after methotrexate injection and outcome in 129 consecutive patients. A 20% decline in hCG levels between days 1 and 4 during methotrexate treatment has a positive predictive value of 97%.

Anxiolytics, hypnotics, and antidepressants dispensed to adolescents in a French region in 2002.

PURPOSE: This study proposes to complete declarative studies by describing the prescriptions of anxiolytics, hypnotics, and antidepressants dispensed to adolescents in a French region in 2002. METHODS: This cross-sectional study analyzes all the hypnotic, anxiolytic, and antidepressant prescriptions (ATC codes beginning with N05B, N05C, and N06A, respectively) sent by adolescents (aged 13-17 years) to the French Health Insurance system of the study region for reimbursement during one year (2002). It was performed in a southern France area with 120,908 adolescents covered by this insurance scheme. Adverse drug reactions (ADRs) recorded in the Pharmacovigilance database were also studied. RESULTS: Three thousand two hundred and eighty-six adolescents (2.7% of adolescent population) had at least one prescription of the studied drugs. This prevalence increased with age and female sex, leading to a maximum of 6.3% for the 17-year-old girls. Two thousand four hundred and thirty-one of adolescents were dispensed anxiolytics, 935 antidepressants, and 548 hypnotics. The most dispensed drugs were zolpidem, zopiclone, and niaprazine for hypnotics; hydroxyzine, etifoxine, and bromazepam for anxiolytics; and paroxetine, sertraline, and fluoxetine for antidepressants. Zolpidem, hydroxyzine, and paroxetine accounted, respectively, for 82.9%, 57.1%, and 59.8% of the prescriptions. 75.5% of hypnotics users had only one prescription, 77.4% for anxiolytics, and 57.4% for antidepressants. Three ADRs were reported. CONCLUSIONS: This study confirms the large use of psychotropics in French adolescents and the influence of age and sex. Also, the results underline treatment for most adolescents is short, which may be beneficial for hypnotics and anxiolytics but not for antidepressants.

Influence of clinical and ultrasound factors on the efficacy of misoprostol in first trimester pregnancy failure.

An observational study including 276 patients with early pregnancy failure was performed to evaluate the clinical and ultrasound factors influencing the efficacy of misoprostol in the treatment of first trimester pregnancy failure. Gestational age did not influence the efficacy of this treatment and the success rate was inversely proportional to parity.

Usefulness of ultrasonography in predicting pleural effusions > 500 mL in patients receiving mechanical ventilation.

STUDY OBJECTIVE: To assess the accuracy of chest ultrasonography in predicting pleural effusions > 500 mL in patients receiving mechanical ventilation. DESIGN: Prospective study. SETTING: Surgical and medical ICU in a teaching hospital. PATIENTS: Forty-four patients receiving mechanical ventilation with indications of chest drainage of a nonloculated pleural effusion. INTERVENTIONS: Diagnosis of pleural effusion was based on clinical examination and chest radiography. Chest drainage was indicated when considered as potentially useful for the patient (hypoxemia and/or weaning failure). Sonograms were performed before drainage at the bedside, in the supine position, and measurements were performed at the end of expiration. Effusions were classified as > 500 mL or < or = 500 mL according to the drained volume. MEASUREMENTS AND RESULTS: The drained volume ranged from 100 to 1,800 mL (mean, 730 +/- 440 mL [+/- SD]). The distance between the lung and posterior chest wall at the lung base (PLDbase) and the distance between the lung and posterior chest wall at the fifth intercostal space (PLD5) were significantly correlated with the drained volume (PLDbase, r = 0.68, p < 0.001; PLD5, r = 0.56, p < 0.001). A PLDbase > 5 cm predicted a drained volume > 500 mL with a sensitivity of 83%, specificity of 90%, positive predictive value of 91%, and negative predictive value of 82%. Interobserver and intraobserver percentages of error were, respectively, 7 +/- 6% and 9 +/- 6% for PLDbase, and 6 +/- 5% and 8 +/- 5% for PLD5. The PaO2/fraction of inspired oxygen ratio significantly increased after chest drainage in patients with collected volumes > 500 mL (p < 0.01). CONCLUSIONS: Bedside pleural ultrasonography accurately predicted a nonloculated pleural effusion > 500 mL in patients receiving mechanical ventilation using simple and reproducible measurements.

Disruption of services in an internal medicine unit due to a nosocomial influenza outbreak.

OBJECTIVE: To describe a nosocomial influenza A outbreak, how it was managed, what impact it had on subsequent delivery of health care, and the additional charges attributable to it DESIGN: Prospective cohort study and microbiological investigation. SETTING: One internal medicine unit in an acute care, university-affiliated hospital. PARTICIPANTS: Twenty-three patients and 22 staff members from February 28 to March 6, 1999. RESULTS: Attack rates were 41% (9 of 22) among patients and 23% (5 of 22) among staff members, with 3 of 14 cases being classified as "certain." The influenza virus isolates were typed as A/SYDNEY/5/97 (H3N2). The index case was a patient who shared a room with the first nosocomial case. Vaccination rates for influenza virus were 43% (10 of 23) among patients and 36% (8 of 22) among staff members. The outbreak resulted in staff members' taking 14 person-days of sick leave. Furthermore, 8 scheduled admissions were postponed and all emergency admissions were suspended for 11 days. Hospital charges attributable to the influenza outbreak totaled $34,179 and the average extra charge per infected patient was $3,798. CONCLUSIONS: Nosocomial influenza outbreaks increase charges and alter the quality of care delivered in acute care settings. Strategies for their prevention need to be evaluated in acute care settings.
