Colistin utilization at a tertiary hospital in South Africa: an opportunity for antimicrobial stewardship practices.

Introduction. Colistin (polymyxin E) has emerged as a last-resort treatment option for multidrug-resistant infections.Hypothesis/Gap Statement. Studies on the use, safety and efficacy of colistin in South Africa are limited.Aim. This study aims to describe the use of colistin and its clinical outcomes at a tertiary public hospital in South Africa.Methodology. We conducted a retrospective review of adult and paediatric patients who received parenteral colistin between 2015 and 2019.Results. A total of 69 patients (26 adults, 13 children and 30 neonates) were reviewed. Acinetobacter baumannii was the most common causative pathogen isolated (70.1 %). Colistin was predominately used to treat septicaemia (75.4 %). It was primarily administered as definitive therapy (71.0 %) and as monotherapy (56.5 %). It was used in 11.5 % of adults with infections susceptible to other antibiotics. Loading doses of intravenous colistin were administered in only 15 (57.7 %) adult patients. Neurotoxicity and nephrotoxicity occurred in 5.8 % and 43.5 % of patients, respectively. Clinical cure was achieved in 37 (53.6 %) patients. On multivariate logistic regression analysis, adults [adjusted odds ratio (aOR), 25.54; 95 % CI, 2.73-238.65; P < 0.01] and children (aOR, 8.56; 95 % CI, 1.06-69.10; P < 0.05) had higher odds of death than neonates.Conclusion. The study identified significant stewardship opportunities to improve colistin prescription and administration. Achieving optimal patient outcomes necessitates a multidisciplinary approach and vigilant monitoring of colistin use.

Characteristics of injuries during the 2006 Lebanon conflict: a three-center retrospective study of survivors, 16 years after the conflict.

Background: Armed conflict injury is a growing public health concern, particularly in regions like the Middle East and North Africa (MENA). The protracted conflicts and political unrest in this region have led to a substantial number of injuries. Despite this, there is still limited understanding of the specific injury patterns stemming from conflicts, such as the 2006 Lebanon conflict. This study aimed to assess the characteristics and burdens of injuries resulting from this conflict, which occurred 16 years prior to this research. Methods: This retrospective study analyzed data of individuals affected by the 2006 Lebanon conflict, across three tertiary care centers. Demographics, injuries, complications, injury management, and hospitalization expenses were extracted from medical records and analyzed using SPSS version 29.0. Categorical variables were presented as counts and proportions, and continuous variables as mean ± standard deviation (SD). Hospital comparisons utilized chi-square or Fisher's exact tests for categorical variables, and one-way ANOVAs for continuous variables. Analysis was conducted from September to November 2023. Results: Across three hospitals, 341 patients were studied, comprising 73.6% males and 26.4% females. Among them, a notable proportion (57.3% males and 34.1% females) fell within the 18-39 age range. Children and adolescents under 18 years accounted for 15.9% of males and 25.9% of females. Blast-related injuries predominated, with 24.5% resulting from direct damage caused by explosive parts and 33.3% from blast wave forces. Extremity trauma occurred in 49.0% of patients, and head/neck trauma in 24.9%. Common injuries, including penetrating, musculoskeletal, and traumatic brain injuries affected 34.9%, 31.1, and 10.0% of patients, respectively. Wound repair, fracture treatment, and debridement were the most performed procedures on 15.5, 13.5 and 9.7% of the patients, respectively. The total cost of care was USD 692,711, largely covered by the Ministry of Public Health (95.9%). Conclusion: Conflict-related injuries significantly contribute to the global burden of disease. Therefore, there is a pressing need to improve national guidelines to prioritize life-threatening cases and potential long-term disabilities. Furthermore, enhancing electronic registry systems to collect clinical data on injured patients is essential for conducting research and better understanding the needs of conflict casualties.

Minimally invasive approach for retrorectal tumors above and below S3: a multicentric tertiary center retrospective study (MiaRT study).

BACKGROUND: Retrorectal tumors are uncommon lesions developed in the retrorectal space. Data on their minimally invasive resection are scarce and the optimal surgical approach for tumors below S3 remains debated. METHODS: We performed a retrospective review of consecutive patients who underwent minimally invasive resection of retrorectal tumors between 2005 and 2022 at two tertiary university hospital centers, by comparing the results obtained for lesions located above or below S3. RESULTS: Of over 41 patients identified with retrorectal tumors, surgical approach was minimally invasive for 23 patients, with laparoscopy alone in 19, with transanal excision in 2, and with combined approach in 2. Retrorectal tumor was above S3 in 11 patients (> S3 group) and below S3 in 12 patients (< S3 group). Patient characteristics and median tumor size were not significantly different between the two groups (60 vs 67 mm; p = 0.975). Overall median operative time was 131.5 min and conversion rate was 13% without significant difference between the two groups (126 vs 197 min and 18% vs 8%, respectively; p > 0.05). Final pathology was tailgut cyst (48%), schwannoma (22%), neural origin tumor (17%), gastrointestinal stromal tumor (4%), and other (19%). The 90-day complication rates were 27% and 58% in the > S3 and < S3 groups, respectively, without severe morbidity or mortality. After a median follow-up of 3.3 years, no recurrence was observed in both groups. Three patients presented chronic pain, three anal dysfunction, and three urinary dysfunction. All were successfully managed without reintervention. CONCLUSIONS: Minimally invasive surgery for retrorectal tumors can be performed safely and effectively with low morbidity and no mortality. Laparoscopic and transanal techniques alone or in combination may be recommended as the treatment of choice of benign retrorectal tumors, even for lesions below S3, in centers experienced with minimally invasive surgery.

Clinical characteristics, visual acuity outcomes, and factors associated with loss of vision among patients with active ocular toxoplasmosis: A retrospective study in a Thai tertiary center.

BACKGROUND: Ocular toxoplasmosis (OT) is the most common cause of infectious uveitis worldwide, including Thailand. This study describes the clinical presentation, visual acuity (VA) outcomes, and factors associated with VA loss in patients with active OT following antiparasitic treatment. METHODOLOGY/PRINCIPAL FINDINGS: A retrospective chart review of patients with active OT treated with antiparasitic drugs between 2010 and 2020 was performed. Outcome measures included clinical characteristics, interval VA, and predictive factors associated with loss of VA ≤ 20/50 at 6 months post-treatment. Ninety-two patients (95 eyes) were enrolled. The median follow-up time was 10.9 months (IQR 4.9-31.8 months). The median age at presentation was 35.9 years, 51% were male, and 92.4% had unilateral OT. Eleven patients (12%) were immunocompromised (HIV infection, eight patients; receiving immunosuppressive agents, three patients). Patients mainly presented with primary retinitis without previous scar (62%), posterior pole lesion (56%), and lesion size of ≤ 2-disc area (75%). Immunocompromised patients showed a significantly larger size of retinitis than immunocompetent patients. Oral trimethoprim/sulfamethoxazole monotherapy was the primary short-term antiparasitic drug prescribed (85%). At the final visit, 21% of all affected eyes suffered VA ≤ 20/200. The cumulative incidence of recurrent OT at three years was 33.9% (95% CI, 19.7%-54.2%). Immunocompromised patients [adjusted odds ratio (aOR) 4.9, p = 0.041], macular lesion (aOR 5.4, p = 0.032), and initial VA ≤ 20/200 (aOR 9.1, p = 0.014) were predictive of having VA ≤ 20/50 at 6 months post-treatment. CONCLUSIONS: Ocular toxoplasmosis mainly presents as unilateral primary retinitis within the posterior pole. Severe VA loss was observed in one-fifth of eyes following treatment with lesion resolution. Immunocompromised patients, eyes with macular lesions, and poor initial VA were associated with poor VA outcomes.

Pediatric health service utilization at tertiary hospitals in Denmark 2000-2018.

Pediatric health service differs between and within countries. To prioritize limited resources, data-driven studies on pediatric tertiary hospital contacts are warranted. This population-based register study identified all contacts with four Danish tertiary hospitals 2000-2018 by 0-17-year-old patients. During 2000-2018, 2,496,001 individuals resided in Denmark while 0-17 years old, and the study described 829,562 inpatient and 3,932,744 outpatient contacts at tertiary hospitals by hospital, sex, age, diagnosis, department, and residence. Male patients accounted for more contacts overall (inpatient 55.51%, outpatient 52.40%) and more contacts with severe chronic disease (inpatient 56.24%, outpatient 54.41%). Median (interquartile range) patient age was 3.09 (0.26-9.96) and 8.48 (2.78-13.70) years for in- and outpatient contacts. Overall, 28.23% and 21.02% of in- and outpatient contacts included a diagnosis of a severe chronic disease, but the proportions differed across hospitals. A pattern of pediatric healthcare directed towards less severe diseases was observed: While the total number of outpatient visits at tertiary hospitals increased from 2000 to 2018, the proportion of these contacts which had a diagnosis of a severe chronic disease decreased. Future comparisons between hospitals regarding pediatric outcomes should consider potential differences in terms of uptake and diagnosis severity. Such findings may have implications for future pediatric organization, nationally and internationally.

Incidence, patterns, and management of frontal sinus fractures: A 10-year retrospective study at a tertiary medical center, Saudi Arabia.

OBJECTIVES: To assess the prevalence of various frontal sinus fractures (FSF) and examine the relationships between these fractures, types of treatments, and potential complications. METHODS: A retrospective study was carried out in King Saud Medical City, Riyadh, Saudi Arabia. The study analyzed the records of patients who were diagnosed and treated with FSF from 2011-2021. Files with missing documents or incomplete treatment were excluded. The retrieved data includes: patients age, gender, types, locations, treatment, and complications of FSF. Data was analyzed by the statistical Package for the Social Sciences Statistics, version 23.0 using descriptive statistics and Chi-square test. RESULTS: A total of 72 cases were included, 94.4% males and 5.6% females. Road traffic accidents were the common cause of trauma (91%). Frontal sinus fractures were unilateral in 59.7% and associated other injuries in 80.6% of cases. Anterior table fractures were the largest proportion (58.3%), followed by anterior and posterior table (37.5%). The carried out surgical procedures were obliteration (23.9%), cranialization and obliteration (23.9%), and fixation only (52.2%). The post-operative complications were categorized into; neurological (22.2%), ophthalmic (15.3%), infection (2.8%), and deformity (16.7%). Anterior and posterior table had the highest percentage among these categories. CONCLUSION: Frontal sinus fractures were mostly required surgical treatment (63.9%) and post-operative complications occurred especially the neurological and ophthalmic. We recommend studies on the association of complications and different types of obliteration materials.

Pattern of Medical Device Adverse Events in a Tertiary Care Hospital in Northern India: An Ambispective Study.

BACKGROUND: Knowledge about the pattern of adverse events caused by medical devices (MDs) is limited in India. We aimed to assess the pattern of MD adverse events (MDAEs) in a tertiary hospital in Northern India. MATERIALS AND METHODS: This descriptive study was conducted ambispectively at various clinical departments of PGIMER, Chandigarh. We followed the guidelines edged by the Materiovigilance Program of India (MvPI) to conduct this study. The prospective study (PS) was done from January to December 2020, with a concurrent retrospective study (RS) proceeding to 3 years to learn more about the reporting culture, demographics, notification status, risk class of defective devices, and the type of adverse events. RESULTS: We received 224 MDAE in the PS and identified 413 MDAE in the RS. Reporting of adverse events to the national MvPI was negligible in the RS. In the PS, nurses reported the majority of MDAEs (65%), followed by doctors (30%). The occurrence of MDAE was higher in males (PS; 52%, RS; 57%) and age groups between 21 and 30 years (PS; 19.1%, RS; 23.2%) in both studies. MDAEs were frequent in low- to moderate-risk devices (class B: 66%) in the PS, while it was documented only for high-risk devices (class C: 51% and class D: 49%) in the RS. Most of the serious adverse events (SAEs) were reported among moderate to high-risk devices, and an increased frequency of SAE (60.4%) was observed among nonnotified MDs. The overall incidence of near-miss events was 14%. CONCLUSION: Knowledge of MDAEs and reporting of defective devices to regulatory authorities is essential to prevent further incidence. Adverse events caused by MDs are ubiquitous irrespective of their risk classification, notification status, and patient demographic factors. Accelerated reporting of MDAE by all cadre of healthcare professionals is urgently required to safeguard the health of Indians.

Quality improvement initiative 'S-A-F-H' to reduce healthcare-associated neonatal sepsis in a tertiary neonatal care unit.

BACKGROUND: Neonatal sepsis is a leading cause of morbidity and mortality among admitted neonates. Healthcare-associated infection (HAI) is a significant contributor in this cohort. LOCAL PROBLEM: In our unit, 16.1% of the admissions developed sepsis during their stay in the unit. METHOD: We formed a team of all stakeholders to address the issue. The problem was analysed using various tools, and the main contributing factor was low compliance with hand hygiene and handling of intravenous lines. INTERVENTIONS: The scrub the hub/aseptic non-touch technique/five moments of hand hygiene/hand hygiene (S-A-F-H) protocol was formulated as a quality improvement initiative, and various interventions were done to ensure compliance with hand hygiene, five moments of hand hygiene, aseptic non-touch technique. The data were collected and analysed regularly with the team members, and actions were planned accordingly. RESULTS: Over a few months, the team could reduce the incidence of HAI by 50%, which has been sustained for over a year. The improvement in compliance with the various aspects of S-A-F-H increased. CONCLUSIONS: Compliance with hand hygiene steps, five moments of hand hygiene and an aseptic non-touch technique using quality improvement methodology led to a reduction in neonatal sepsis incidence in the unit. Regular reinforcement is required to maintain awareness of asepsis practices and implementation in day-to-day care and to bring about behavioural changes.

Epidemiology of non-trauma orthopedic conditions among inpatients admitted at a tertiary teaching and referral hospital in Kenya: A chart review.

Non-traumatic orthopedic conditions are pathological conditions involving musculoskeletal system that includes muscles, tendons, bone and joints and associated with frequent medical and surgical care and high treatment costs. There is paucity of information on the pattern of non-traumatic orthopedic conditions in low and middle income countries. The purpose of this study was to determine the epidemiology of non-traumatic orthopedic conditions among inpatients at the Kenyatta National Hospital in Kenya. This was a cross-sectional study with a sample of 175 charts reviewed. Approximately, 70.3% of the inpatients were aged between 25 to 64 years of age with the mean age of 39.97 years (STD 18.78). Ever married tended to be older 53.5 (95% CI: 46.8-60.2) years than other marital statuses. Approximately, 60.6% were males, 38.9% had comorbidities and 49.1% were casuals or unemployed. All inpatients were Kenyans with Nairobi County comprising 52.6% of all inpatients. Approximately, 77.7% were self-referrals. The commonest non-trauma orthopaedic conditions were infection and non-union (35.4%) and spinal degenerative diseases (20.60%) and the least was limb deformities (1.70%). Compared to females, males were 3.703 (p<0.001) times more likely to have infection and non-union. Patients with primary, secondary and tertiary education were 88.2% (p<0.001), 75.6% (p<0.001) and 68.1% (p = 0.016) less likely to have infection and non-union compared to those with no or preschool education. Widows were 8.500 (p = 0.028) times more likely to have spinal degenerative disease than married. Males were 70.8% (p = 0.031) less likely to have osteoarthritis than females. Inpatients with secondary education were 5.250 (p = 0.040) times more likely to have osteoarthritis than those with no or preschool education. In conclusion, majority of inpatients were young and middle aged adults. Infection and non-union and spinal degenerative diseases were the most common non-trauma orthopedic conditions. While males and those with low education were more likely to have infection and non-union, married were more likely to have spinal degenerative disease. Osteoarthritis was more likely among female admissions.

Various clinical manifestations of 223 patients with IgE deficiency in a tertiary hospital in China: A cross-sectional study.

High Immunoglobulin E(IgE) levels associated with hypersensitivity or parasitic infection were well established, but the clinical significance of ultra-low IgE was largely unknown. Previous studies indicated these patients have an elevated risk of cancer, but large-scale epidemiological studies on the prevalence and clinical manifestations of these ultra-low IgE patients are still lacking. A total of 62,997 patients who were admitted to the First Affiliated Hospital of Wenzhou Medical University and had IgE level tests from January 2010 to March 2020 were included. Patients with serum IgE levels < 2 IU/mL were defined to have ultra-low IgE. And the clinical characteristics of these patients were retrospectively analyzed based on electronic medical record system and follow-up. A total of 223 patients (223/62,997, 0.35%) had ultra-low IgE were documented in 62,997 patients who had IgE tests. Among the clinical manifestations of these 223 ultra-low IgE patients, infection ranked first (125/223, 56.05%), following allergic diseases (51/223, 22.87%), hematological disorders (37/223, 16.59%), tumor (27/223, 12.11%) and autoimmune diseases (23/223, 10.31%). To the best of our knowledge, we first reported that the prevalence and clinical characteristics of 223 ultra-low IgE patients in China. The most common comorbidities were infection, allergic diseases, hematological disorders, tumor and autoimmune diseases.

Molecular epidemiology and antimicrobial resistance in Clostridioides difficile strains isolated from children and adolescents in a tertiary referral pediatric hospital in Fortaleza, Brazil.

BACKGROUND: C. difficile has been increasingly reported as a cause of gastrointestinal disease in children, ranging from mild self-limiting diarrhea to severe conditions such as pseudomembranous colitis and toxic megacolon. Only two pediatric research groups reported the presence of C. difficile infection in Brazilian children, but no previous research has examined C. difficile infection among children in northeastern Brazil. This prospective cross-sectional study investigated the molecular epidemiology and antimicrobial resistance of C. difficile strains isolated from children and adolescents with diarrhea referred to a tertiary pediatric hospital in Brazil while exploring the associated risk factors. RESULTS: Toxin positivity or C. difficile isolation was found in 30.4 % (17/56) samples. C. difficile was isolated from 35 % (6/17) samples. Four toxigenic strains were identified (tpi+, tcdA+, tcdB+, cdtB-, without tcdC deletions) belonging to PCR ribotypes and PFGE-pulsotypes: 046 (new pulsotype 1174), 106 (NAP11), 002 (new pulsotype 1274), 012 (new pulsotype NML-1235). Two of the six isolates belonging to ribotypes 143 and 133 were non-toxigenic. All toxigenic strains were sensitive to metronidazole and vancomycin. Regarding the clinical manifestation, diarrhea lasted an average of 11 days, ranging from 3 to 50 days and was often associated with mucus and/or blood. All six patients from whom the C. difficile was isolated had a chronic disease diagnosis, with these comorbidities as the main risk factors. CONCLUSION: Our study enhances our understanding of the present epidemiological landscape of C. difficile-associated diarrhea (CDI) among children in northeastern Brazil, reveling a substantial CDI frequency of 30.4 %, with toxigenic strains detected in 76.4 % of cases, highlighting a higher prevalence compared to earlier Brazilian studies. In the globalized world, an understanding of disease-generating strains, the associated risk factors, clinical manifestation, and antimicrobial sensitivity has fundamental epidemiological importance and draws attention to preventive measures, allowing for more decisive action.

Aspergillosis in Critically Ill Patients with and Without COVID-19 in a Tertiary Hospital in Southern Brazil.

The impact of invasive pulmonary aspergillosis (IPA) on non-neutropenic critically ill patients in intensive care units (ICU) has been demonstrated in recent decades. Furthermore, after the start of the COVID-19 pandemic, COVID-19 associated with pulmonary aspergillosis (CAPA) has become a major concern in ICUs. However, epidemiological data from different regions are scarce. We evaluated the prevalence and clinical-epidemiological data of IPA in patients with COVID-19 requiring mechanical ventilation (MV) in the ICU ("severe COVID-19") and non-COVID ICU patients in MV of a tertiary hospital in the southern region of Brazil. Eighty-seven patients admitted between June 2020 and August 2022 were included; 31 with severe COVID-19. For the diagnosis of IPA or CAPA, algorithms including host factors and mycological criteria (positive culture for Aspergillus spp., immunoassay for galactomannan detection, and/or qPCR) were utilized. The overall incidence of IPA and CAPA in our ICU was 73 cases/1000 ICU hospitalizations. Aspergillosis occurred in 13% (4/31) of the COVID-19 patients, and in 16% (9/56) of the critically ill patients without COVID-19, with mortality rates of 75% (3/4) and 67% (6/9), respectively. Our results highlight the need for physicians enrolled in ICU care to be aware of aspergillosis and for more access of the patients to sensitive and robust diagnostic tests by biomarkers detection.

Prevalence, Severity Patterns and Risk Factors of Bronchopulmonary Dysplasia in Preterm Infants Younger than 32 Weeks of Gestation in a Tertiary Centre in Oman.

Objectives: This study aimed to determine the rate and severity patterns of bronchopulmonary dysplasia (BPD) and identify antenatal and postnatal factors associated with BPD in preterm infants <32 weeks of gestational age (GA). Methods: This retrospective observational study included preterm neonates <32 weeks of gestation admitted into the neonatal intensive care unit between January 2010 and December 2017 at Sultan Qaboos University Hospital, Muscat, Oman. A data set of antenatal and perinatal factors were collected. BPD was defined as the need for oxygen and/or respiratory support at 36 weeks post-menstrual age (PMA). Infants with and without BPD were compared in their antenatal and perinatal factors. Results: A total of 589 preterm infants <32 weeks were admitted. Among them, 505 (85.7%) survived to 36 weeks' PMA and 90 (17.8%) had BPD. The combined BPD and mortality rate was 28.4%. Grades 1, 2 and 3 BPD constituted 77.8%, 7.8% and 14.4%, respectively. BPD was associated with lower GA, lower birth weight, need for intubation at resuscitation, lower Apgar scores, longer duration of ventilation, surfactant therapy and higher rates of neonatal morbidities. On binary logistic regression analysis, predictors of BPD were longer duration of ventilation, intraventricular haemorrhage (IVH) and necrotising enterocolitis (NEC). Conclusion: In an Omani centre, 17.8% of preterm infants (<32 weeks GA) developed BPD. Various perinatal and neonatal factors were associated with BPD. However, longer duration of ventilation, IVH grades 1 and 2 and NEC stages II and III were significant predictors. Future multicentre research is necessary to provide the overall prevalence of BPD in Oman to help optimise the resources for BPD prevention and management in preterm infants.

Impact of SARS-CoV-2 Pandemic on Emergency Hospitalizations for Acute Respiratory Infections: The Experience of a Paediatric Tertiary Care Hospital in Italy.

BACKGROUND: Acute respiratory infections (ARIs) are a major healthcare issue in children. The SARS-CoV-2 pandemic changed the epidemiology of ARIs; the aims of this study are to characterize the epidemiological trend of ARI emergency hospitalizations and virology results and to estimate the association of ARI emergency hospitalizations with respiratory viruses from January 2018 to June 2023. METHODS: This study was carried out in an Italian tertiary care children's hospital (Bambino Gesù Children's Hospital). The demographic and clinical information of children who accessed the Emergency Department (ED) with ARI and were hospitalized were retrospectively extracted from the electronic health records. Multivariate linear regression model was used to compare the number of ARI hospital admissions with the reported temporal trends in viruses diagnosed from respiratory samples throughout the same time period. RESULTS: During the study period, there were 92,140 ED visits and 10,541 hospitalizations due to ARIs, reflecting an admission rate of 11.4%. The highest proportion of hospitalizations occurred in infants ≤ 1 year of age (n = 4840, 45.9% of total admissions), with a hospitalization rate of 22.6%. Emergency hospitalizations aligned closely with the predictions made by the multivariate regression model; peaks in hospitalizations reflected Respiratory Syncytial Virus (RSV) circulation. CONCLUSIONS: ARI hospital urgent admissions are a relevant component of ARI disease burden in children. RSV prevention and control are crucial to limit the risk of urgent hospitalizations due to ARIs.

Genotype Distribution and Prevalence of High-Risk Human Papillomavirus among Pregnant Women and Maternal-Fetal Pregnancy Outcomes in a Tertiary Hospital in Beijing, China.

BACKGROUND: High-risk human papillomavirus (HR-HPV) infection is the primary reason for cervical cancer and precancerous lesions in females. Specific immune alterations in pregnancy led to greater HR-HPV replication and reduced clearance of HR-HPV infection. This study retrospectively obtained and analyzed data from a tertiary hospital in Beijing, China. We aimed to ascertain both the genotype distribution and prevalence of HR-HPV in pregnant females. Moreover, we sought to analyze the association of HR-HPV with maternal-fetal pregnancy outcomes. METHODS: The retrospective observational cohort study was divided into two parts. Part I evaluated the genotype distribution and prevalence of HR-HPV. It encompassed 6285 pregnant women who underwent a routine pregnancy check-up, Thin Prep cytology test (TCT), and HR-HPV diagnosis during weeks 12-14 of gestation between January 1, 2013, and December 31, 2021. Part II analyzed the association between HR-HPV infection and maternal-fetal pregnancy outcome. Through a nearest-neighbor 1:1 propensity score matching (PSM), we matched HR-HPV-positive and HR-HPV-negative pregnant women using caliper width equal to 0.02. After PSM, 171 HR-HPV-positive and 171 HR-HPV-negative pregnant women were included to analyze the association between HR-HPV infection and maternal-fetal pregnancy outcome. RESULTS: In total 737 (11.73%) pregnant women were HR-HPV positive. The five most common genotypes of HR-HPV were HPV-52 (2.90%), HPV-58 (2%), HPV-16 (1.94%), HPV-51 (1.38%), and HPV-39 (1.29%). As for age-specific HPV prevalence, a "U-shaped" pattern was observed. The first and second peaks were detected in pregnant females aged <25 years and those aged ≥35 years, respectively. Our study found no significant difference between the HR-HPV-positive and the HR-HPV-negative pregnant females in the following maternal-fetal pregnancy outcomes: spontaneous abortion (1.2% for HR-HPV positive, 0% for HR-HPV negative, p = 0.478), preterm delivery (4.7% for HR-HPV positive, 5.3% for HR-HPV negative, p = 0.804), premature rupture of membrane (28.8% for HR-HPV positive, 22.8% for HR-HPV negative, p = 0.216), preeclampsia (7.6% for HR-HPV positive, 7.6% for HR-HPV negative, p = 1), oligohydramnios (8.2% for HR-HPV positive, 7% for HR-HPV negative, p = 0.683), fetal growth restriction (1.8% for HR-HPV positive, 0.6% for HPV negative, p = 0.615), placenta previa (1.2% for HR-HPV positive, 0.6% for HR-HPV negative, p = 1), postpartum hemorrhage (8.9% for HR-HPV positive, 11.2% for HR-HPV negative, p = 0.47). There was also no significant difference in delivery mode or birth weight between the two groups. CONCLUSIONS: HPV-16, 52, and 58 were the most prevalent infection genotypes in pregnant females. The study showed no significant differences between HR-HPV-positive and HR-HPV-negative groups in the maternal-fetal pregnancy outcomes.

Presence and Significance of Multiple Respiratory Viral Infections in Children Admitted to a Tertiary Pediatric Hospital in Italy.

Viral co-infections are frequently observed among children, but whether specific viral interactions enhance or diminish the severity of respiratory disease is still controversial. This study aimed to investigate the type of viral mono- and co-infections by also evaluating viral correlations in 3525 respiratory samples from 3525 pediatric in/outpatients screened by the Allplex Respiratory Panel Assays and with a Severe Acute Respiratory Syndrome-COronaVirus 2 (SARS-CoV-2) test available. Overall, viral co-infections were detected in 37.8% of patients and were more frequently observed in specimens from children with lower respiratory tract infections compared to those with upper respiratory tract infections (47.1% vs. 36.0%, p = 0.003). SARS-CoV-2 and influenza A were more commonly detected in mono-infections, whereas human bocavirus showed the highest co-infection rate (87.8% in co-infection). After analyzing viral pairings using Spearman's correlation test, it was noted that SARS-CoV-2 was negatively associated with all other respiratory viruses, whereas a markedly significant positive correlation (p < 0.001) was observed for five viral pairings (involving adenovirus/human bocavirus/human enterovirus/metapneumoviruses/rhinovirus). The correlation between co-infection and clinical outcome may be linked to the type of virus(es) involved in the co-infection rather than simple co-presence. Further studies dedicated to this important point are needed, since it has obvious implications from a diagnostic and clinical point of view.

COVID-19 in three waves in a tertiary referral hospital in Belgium: a comparison of patient characteristics, management, and outcome.

PURPOSE: Few studies have compared patient characteristics, clinical management, and outcome of patients with COVID-19 between the different epidemic waves. In this study, we describe patient characteristics, treatment, and outcome of patients admitted for COVID-19 in the Antwerp University Hospital over the first three epidemic waves of 2020-2021. METHODS: Retrospective observational study of COVID-19 patients in a Belgian tertiary referral hospital. All adult patients with COVID-19, hospitalized between February 29, 2020, and June 30, 2021, were included. Standardized routine medical data was collected from patient records. Risk factors were assessed with multivariable logistic regression. RESULTS: We included 722 patients, during the first (n = 179), second (n = 347) and third (n = 194) wave. We observed the lowest disease severity at admission during the first wave, and more elderly and comorbid patients during the second wave. Throughout the subsequent waves we observed an increasing use of corticosteroids and high-flow oxygen therapy. In spite of increasing number of complications throughout the subsequent waves, mortality decreased each wave (16.6%,15.6% 11.9% in 1st, 2nd and 3rd wave respectively). C-reactive protein above 150 mg/L was predictive for the need for intensive care unit admission (odds ratio (OR) 3.77, 95% confidence interval (CI) 2.32-6.15). A Charlson comorbidity index ≥ 5 (OR 5.68, 95% CI 2.54-12.70) and interhospital transfers (OR 3.78, 95% CI 2.05-6.98) were associated with a higher mortality. CONCLUSIONS: We observed a reduction in mortality each wave, despite increasing comorbidity. Evolutions in patient management such as high-flow oxygen therapy on regular wards and corticosteroid use may explain this favorable evolution.

Adverse neonatal outcome associated with maternal tuberculosis in a public tertiary centre: a retrospective cohort study.

INTRODUCTION: The aim of this study was to evaluate a group of infants born to women with tuberculosis (TB) during pregnancy to determine the neonatal morbidities and its outcomes associated with tuberculosis in pregnancy. MATERIALS AND METHODS: Data from January 2007 to December 2021 was collected for analysis as part of a retrospective cohort study. This study was conducted in a tertiary public hospital in Malaysia, Hospital Sultan Idris Shah (HSIS). Cases were identified from the hospital's bacille Calmette-Guerin (BCG) vaccination notification forms and merged with records from the neonatal intensive care unit's census. Controls were infants born to mothers unaffected by TB within the same hospital and year as the index case (1:4 ratio). Descriptive statistics and logistic regression were used to analyse the data. The main outcome measures were the risk of congenital tuberculosis, premature birth, low birth weight, small for gestational age and low APGAR score.

Mortality after emergency department discharge: an analysis of 453599 cases. / Mortalidad tras el alta desde el servicio de urgencias hospitalario: análisis de 453.599 episodios.

OBJECTIVES: To quantify and analyze mortality in patients who die within 30 days of discharge home from a hospital emergency department (ED). MATERIAL AND METHODS: All patients older than 14 years of age who were discharged home from the ED of a tertiary care hospital over a 5-year period were included. We collected age, sex, and other demographic variables, as well as the Charlson Comorbidity Index (CCI). The outcome variables of interest were 7-day and 30-day mortality and cause of death. Deaths were classified as expected and directly related to the emergency, expected but not directly related, unexpected and directly related, and unexpected and not directly related. A death was classified as an adverse event if it was directly related to a problem of diagnosis or management in the ED, underestimation of severity, or complications of a procedure. RESULTS: Of 519312 patients attended in the ED, 453 599 were discharged home. Of those discharged, 148 died at home within 7 days (32.63 deaths/100 000 discharges) and 355 died within 30 days (78.48 deaths/100 000 discharges). One hundred thirteen deaths (31.8%) were expected and related to the emergency 24.91/100 000), 169 (47.6%) were expected but unrelated 37.26/100 000), 4 (1.1%) were unexpected and related 1.10/100000), and 69 (19.4%) were unexpected and unrelated 15.21/100000). Deaths were considered adverse events related to ED care in 24.2% of the cases. Underestimation of severity was responsible for the highest proportion (10.7%) of such deaths. The median age of patients who died was 83 years, and the median Charlson comorbidity index (CCI) was 6. The most common cause of death was a malignant tumor (23.0%), followed by congestive heart failure (20.2%) and atherosclerotic cardiovascular disease (13.2%). Unexpected deaths related to ED care were significantly related to a higher proportion of adverse events related to diagnosis (P = .001), management (P = .004), and underestimation of severity (P .001). CONCLUSION: Early deaths after discharge home from a hospital ED occured in patients of advanced age with concomitant conditions. The main clinical settings were neoplastic and cardiovascular disease. Seven-day and 30-day mortality rates directly related to the emergency visit were low. Adverse events related to ED care played a role in about a quarter of the deaths after discharge.

OBJETIVO: Cuantificar y analizar la mortalidad de los pacientes dados de alta directamente desde un servicio de urgencias hospitalario (SUH) y que fallecen dentro de los primeros 30 días en el domicilio. METODO: Se incluyeron todos los pacientes mayores de 14 años dados de alta desde el SUH a domicilio durante 5 años en un hospital terciario. Se recogieron como variables demográficas, edad, sexo e índice de Charlson. Como variable evolutiva se investigó la mortalidad a 30 días, y si esta ocurrió en 7 o menos días o más de 7 días y la causa del fallecimiento. La mortalidad se clasificó como esperada y directamente relacionada, esperada y no directamente relacionada, no esperada y directamente relacionad, y no esperada y no directamente relacionada. Se determinó como evento adverso (EA) relacionada con la mortalidad si la muerte estaba relacionada con un problema diagnóstico o de manejo, de infraestimación de la gravedad o complicaciones del procedimiento. RESULTADOS: Fueron atendidos 519.312 episodios de los que 453.599 fueron dados de alta al domicilio. De estos, 148 fallecieron en domicilio a los 7 días (32,63/100.000 altas) y 355 fallecieron en los 30 días después del alta (78,48/100.000 altas): el 31,8% (n = 113) fueron fallecimientos esperados y relacionados (24,91/100.000 altas), el 47,6% (n = 169) esperados y no relacionados (37,26/100.000 altas), el 1,1% (n = 4) no esperados y relacionados (1,10/100.000 altas) y 19,4% (n = 69) no esperados y no relacionados (15,21/100.000 altas). En un 24,2% de los pacientes se detectaron EA relacionados con la asistencia en urgencias, el más frecuente EA fue la infraestimación de la gravedad (10,7%). La mediana de edad de los pacientes fallecidos era de 83 años y una mediana del índice de comorbilidad de Charlson (ICC) de 6 puntos. La principal etiología de fallecimiento fue la neoplasia maligna (23,0%), seguida de insuficiencia cardiaca congestiva (20,2%) y enfermedad cardiaca arteriosclerótica (13,2%). En los fallecimientos no esperados y relacionados, destaca una mayor proporción de EA por causa de problemas diagnósticos (p = 0,015), de manejo (p = 0,028) y de infraestimación de la gravedad (p = 0,004). CONCLUSIONES: Los pacientes que fallecen de forma precoz tras el alta de SUH en el domicilio son ancianos con comorbilidad y donde las principales causas de muerte son las enfermedades neoplásicas y las enfermedades cardiacas. Las muertes no esperadas y directamente relacionadas son poco frecuentes a los 7 y 30 días del alta. En una cuarta parte de los pacientes se detectaron EA relacionados con la asistencia en urgencias.
