RESUMO
Evaluating 100 adult coronavirus disease 2019 (COVID-19) patients at a Madrid hospital, we identified a mismatch between current clinical trial designs and the evolving profile of hospitalized patients. Most patients were ineligible due to design constraints, suggesting a need to rethink trial criteria for a more accurate representation of the hospitalized COVID-19 cohort.

Embryofetal development (EFD) studies are performed to characterize risk of drugs in pregnant women and on embryofetal development. In line with the ICH S5(R3) guideline, these studies are generally conducted in one rodent and one non-rodent species, commonly rats and rabbits. However, the added value of conducting EFD studies in two species to risk assessment is debatable. In this study, rat and rabbit EFD studies were evaluated to analyze the added value of a second species. Information on rat and rabbit EFD studies conducted for human pharmaceuticals submitted for marketing authorization to the European Medicines Agency between 2004 and 2022 was collected from the database of the Dutch Medicines Evaluation Board, along with EFD studies conducted for known human teratogens. In total, 369 compounds were included in the database. For 55.6% of the compounds similar effects were observed in rat and rabbit EFD studies. Discordance was observed for 44.6% of compounds. Discordance could often be explained based on occurrence of maternal toxicity or the compound's mechanism of action. For other compounds, discordance was considered of limited clinical relevance due to high exposure margins or less concerning EFD toxicity. For 6.2%, discordance could not be explained and was considered clinically relevant. Furthermore, for specific therapeutic classes, concordance between rat and rabbit could vary. In conclusion, in many cases the added value of conducting EFD studies in two species is limited. These data could help identify scenarios in which (additional) EFD studies could be waived or create a weight-of-evidence model to determine the need for (additional) EFD studies.
RESUMO
Although angiotensin-converting enzyme inhibitors (ACEis) and angiotensin II receptor blockers (ARBs) play critical roles in the treatment of heart failure with reduced or mildly reduced ejection fraction (HFrEF/HFmrEF; left-ventricular ejection fraction ≤ 50%), the ideal timing for initiation in patients with acute heart failure (AHF) is unclear. We sought to clarify the timing and safety of ACEi/ARB prescription relative to hemodynamic stabilization (pre or post) in patients hospitalized with acute HFrEF/HFmrEF. This was a retrospective, observational analysis of electronic data of patients hospitalized for AHF at 17 Japanese hospitals. Among 9107 patients hospitalized with AHF, 2648 had HFrEF/HFmrEF, and 83.0% met the hemodynamic stabilization criteria within 10 days of admission. During hospitalization, 63.5% of patients with HFrEF/HFmrEF were prescribed an ACEi/ARB, 79.4% of which were prescribed pre-stabilization. In a multivariable analysis, patients treated with an ACEi/ARB pre-stabilization were more likely to have comorbid hypertension, diabetes mellitus, or ischemic heart disease. ACEi/ARB prescription timing was not associated with adverse events, including hypotension and renal impairment, and early prescription was associated with a lower incidence of subsequent worsening of HF. In clinical practice, more hospitalized patients with AHF received an ACEi/ARB before compared with after hemodynamic stabilization, and no safety concerns were observed. Moreover, early prescription may be associated with a lower incidence of worsening HF.

BACKGROUND: The adoption of predictive algorithms in health care comes with the potential for algorithmic bias, which could exacerbate existing disparities. Fairness metrics have been proposed to measure algorithmic bias, but their application to real-world tasks is limited. OBJECTIVE: This study aims to evaluate the algorithmic bias associated with the application of common 30-day hospital readmission models and assess the usefulness and interpretability of selected fairness metrics. METHODS: We used 10.6 million adult inpatient discharges from Maryland and Florida from 2016 to 2019 in this retrospective study. Models predicting 30-day hospital readmissions were evaluated: LACE Index, modified HOSPITAL score, and modified Centers for Medicare & Medicaid Services (CMS) readmission measure, which were applied as-is (using existing coefficients) and retrained (recalibrated with 50% of the data). Predictive performances and bias measures were evaluated for all, between Black and White populations, and between low- and other-income groups. Bias measures included the parity of false negative rate (FNR), false positive rate (FPR), 0-1 loss, and generalized entropy index. Racial bias represented by FNR and FPR differences was stratified to explore shifts in algorithmic bias in different populations. RESULTS: The retrained CMS model demonstrated the best predictive performance (area under the curve: 0.74 in Maryland and 0.68-0.70 in Florida), and the modified HOSPITAL score demonstrated the best calibration (Brier score: 0.16-0.19 in Maryland and 0.19-0.21 in Florida). Calibration was better in White (compared to Black) populations and other-income (compared to low-income) groups, and the area under the curve was higher or similar in the Black (compared to White) populations. The retrained CMS and modified HOSPITAL score had the lowest racial and income bias in Maryland. In Florida, both of these models overall had the lowest income bias and the modified HOSPITAL score showed the lowest racial bias. In both states, the White and higher-income populations showed a higher FNR, while the Black and low-income populations resulted in a higher FPR and a higher 0-1 loss. When stratified by hospital and population composition, these models demonstrated heterogeneous algorithmic bias in different contexts and populations. CONCLUSIONS: Caution must be taken when interpreting fairness measures' face value. A higher FNR or FPR could potentially reflect missed opportunities or wasted resources, but these measures could also reflect health care use patterns and gaps in care. Simply relying on the statistical notions of bias could obscure or underplay the causes of health disparity. The imperfect health data, analytic frameworks, and the underlying health systems must be carefully considered. Fairness measures can serve as a useful routine assessment to detect disparate model performances but are insufficient to inform mechanisms or policy changes. However, such an assessment is an important first step toward data-driven improvement to address existing health disparities.

Retrospective review is a key to designing effective food safety measures. Despite the reported reduction of Salmonella prevalence in poultry products, there has not been a concomitant reduction of the overall incidence of Salmonella illnesses reported to the US Foodborne Diseases Active Surveillance Network (FoodNet) since 1996. However, there have been significant annual trends among Salmonella serotypes. This analysis examines trends in the reported incidence of illness due to poultry- and nonpoultry associated Salmonella serotypes. Overall, the findings indicate declining trends in illness due to the poultry-associated serotypes and increasing trends in illness due to Salmonella serotypes not associated with poultry.

The incidence of human illness due to Salmonella Infantis reported to Foodborne Diseases Active Surveillance Network and the prevalence of Infantis on chicken carcasses reported by the United States Department of Agriculture Food Safety and Inspection Service have increased significantly in the past decade. However, the trends do not appear coincident, as would be expected if the increased prevalence in chicken led to the increase in the incidence of human illness. Salmonella Infantis incidence and prevalence trends are analyzed using penalized B-spline methods for generalized additive regression models. The association between the two time series is analyzed using time-lagged rank-order cross-correlation. Geographic variations in reported incidence and trends are also explored. The increase in human incidence of Salmonella Infantis began circa 2011. The increase in chicken carcass prevalence began circa 2015. A 4-year lag on chicken carcass prevalence maximizes the rank-order cross-correlation with the incidence of illness. While chicken consumption undoubtedly contributes to the incidence of human illness due to Salmonella Infantis, the initial increase in reported illness was likely due to one or more other transmission pathways. Other potential transmission pathways include non-chicken foodborne, waterborne, person-to-person, animal contact, and environmental.
RESUMO
BACKGROUND: The diagnosis of attention-deficit/hyperactivity disorder (ADHD) in adolescence and adulthood is particularly challenging because retrospective confirmation of previous childhood ADHD is mandatory. Therefore, collecting valid diagnostic information about behavior at school is important. Primary school reports often contain descriptions of academic performance and social behaviors associated with ADHD criteria. Yet, there is no systematic approach available how to assess such reports quantitatively, and therefore, there is also no study on how valid such an approach could predict an ADHD diagnosis. METHODS: We examined primary school reports from Germany (ADHD: n = 1197, typically developing controls: n = 656) for semantic references to ICD-10/DSM-5 main and sub-criteria of ADHD. Descriptions were assessed on a quantitative scale (blinded clinical expert rating) for disorder-associated behaviors (symptoms scale) as well as for desired, adaptive behaviors (competencies scale) according to these criteria. The scores of these developed scales have been summarized to summary scores. Scores were analyzed using linear mixed models, and sensitivity and specificity were estimated using receiver operating characteristics (ROC). RESULTS: Ratings showed highly significant differences between school reports of children with and without ADHD. For the summary scores, both symptoms and competencies scales showed high diagnostic accuracy (ROC area under the curve at least 0.96) with best discrimination when combining both into an integrated index (sensitivity and specificity > 0.97). CONCLUSIONS: Our findings suggest that systematic quantitative analysis of primary school reports should be further explored to construct a valid instrument for retrospective assessment of childhood ADHD criteria to aid the diagnostic process in adolescents and adults.
RESUMO
OBJECTIVES: Evaluate real-world epidemiologic trends and treatment patterns in newly diagnosed patients with locally advanced or metastatic urothelial carcinoma (la/mUC) in Japan. METHODS: This retrospective analysis included adults with newly diagnosed la/mUC in Japan (January 2015-December 2019) from a nationwide-linked electronic medical record Diagnostic Procedure Combination claims dataset. Outcomes included epidemiologic trends (incidence and prevalence), baseline demographics, clinical characteristics, and treatment patterns in newly diagnosed patients with la/mUC before (2015-2017) and after (2018-2019) approval of pembrolizumab in Japan. RESULTS: Of 975 patients included, 76.4% were men; 71.6% were aged 70 years or older. Most cases (70.5%) were of the bladder. Between 2015 and 2019, the annual age-adjusted incidence increased from 6.8 to 12.4 per 100 000; the annual age-adjusted period prevalence increased from 13.0 to 25.2 per 100 000; and 307 (31.5%) and 668 (68.5%) patients were diagnosed from 2015 to 2017 and 2018 to 2019, respectively. Overall, 731 (75%) patients received systemic anticancer therapy; all received 1 line and 50.2% received 2 lines of therapy; 78.3% of patients received gemcitabine plus platinum-based therapy and 2.2% received pembrolizumab as first-line treatment. First-line treatment rates increased from 69.4% to 77.5% after pembrolizumab approval. Of 367 patients who received second-line treatment, 22.3% received gemcitabine plus platinum-based therapy; 14.7% received pembrolizumab. CONCLUSIONS: In the Japanese regions considered, incidence and prevalence of newly diagnosed la/mUC increased over time and first-line treatment with pembrolizumab increased after approval.

BACKGROUND: Ischaemic stroke remains a significant global health challenge, associated with high mortality rates. While the Braden Scale is traditionally employed to assess pressure ulcer risk, its potential to predict mortality among the intensive care unit (ICU) patients with ischaemic stroke has not been thoroughly investigated. AIM/S: This study evaluates the predictive value of the Braden Scale for 30-day mortality among patients with ischaemic stroke admitted to ICU. STUDY DESIGN: We conducted a retrospective analysis of 4710 adult patients with ischaemic stroke from the Medical Information Mart for Intensive Care (MIMIC)-IV database. The association between the Braden Scale scores and 30-day mortality was assessed using receiver operating characteristic (ROC) curve analysis, Cox regression models and Kaplan-Meier survival estimates. RESULTS: Patients with Braden Scale scores ≤ 15.5 showed significantly higher 30-day mortality rates (p-value < 0.001; hazard ratio (HR): 2.08, 95% confidence interval (CI): 1.71-2.53). The area under the ROC curve (AUC) was 0.71, demonstrating good predictive performance. Multivariate analysis confirmed the Braden Scale as an independent predictor of mortality, after adjusting for age, gender and comorbidities. CONCLUSIONS: The Braden Scale effectively identifies high-risk ischaemic stroke patients in ICU settings, endorsing its integration into routine assessments to facilitate early intervention strategies. RELEVANCE TO CLINICAL PRACTICE: Integrating the Braden Scale into routine ICU evaluations can enhance mortality risk stratification and improve patient care tailoring.
RESUMO
Objective: To observe the treatment of severe preeclampsia in newborns with enoxaparin sodium combined with magnesium sulfate. Methods: A retrospective analysis was conducted on the clinical data of 80 patients with severe preeclampsia admitted to Hefei Second People's Hospital, China from January 2019 to December 2020. Treatment records showed that 40 cases received magnesium sulfate treatment (single group), and 40 cases received enoxaparin sodium combined with magnesium sulfate treatment (combination group). Levels of D-dimer, soluble fms-like tyrosine kinase 1 (sFlt-1), placental growth factor (PLGF), Apgar scores of newborns delivered before and after treatment were compared. Gestation weeks and incidence of adverse reactions were analyzed. Results: After treatment, levels of D-dimer, sfit-1 and adverse reactions in the combination group were significantly lower than those in the single group (P<0.05), and the level of PLGF, newborn Apgar score and length of gestation were significantly higher than those in the single group (P<0.05). Conclusion: Compared to magnesium sulfate alone, the combination of enoxaparin sodium and magnesium sulfate in the treatment of pregnant women with severe preeclampsia can more effectively regulate the cytokine level of patients, improve pregnancy outcome, and improve neonatal Apgar score. The incidence of adverse reactions is low, making it a safe and efficient treatment modality.
RESUMO
BACKGROUND: Endoscopic resection (ER) is a minimally invasive treatment for esophageal cancer that sometimes causes complications. To understand the real-world incidence and risk factors for these complications, a nationwide survey was conducted across Japan. METHODS: This retrospective multicenter study included patients who underwent ER for esophageal cancer from April 2017 to March 2018 (2017 complication analysis) and April 2021 to March 2022 (2021 complication analysis). The study assessed the complication rates and conducted risk factor analyses for endoscopic submucosal dissection (ESD) using data for these patients, with exclusions based on specific criteria to ensure data accuracy. RESULTS: In the 2021 complication analysis, there were two mortalities highly likely attributable (0.03%) to ER and one mortality possibly attributable (0.01%) to ER. Intraoperative perforation, delayed bleeding, and pneumonia occurred in 137 cases (1.8%), 44 cases (0.6%), and 130 cases (1.7%), respectively. In the multivariate analysis for complications after ESD, low ER volume of the facility was an independent risk factor for perforation, while lesion location in the cervical or upper thoracic esophagus was an independent factor for reduced risk of perforation. Age ≥ 80 years was a risk factor for pneumonia, while use of traction techniques was a factor for reduced risk of pneumonia. Lesions located in the middle thoracic esophagus had a lower risk of stricture, and the risk of stricture increased as the circumferential extent of the lesion increased. CONCLUSIONS: This large-scale study provided detailed insights into the complications associated with esophageal ER and identified significant risk factors.
RESUMO
BACKGROUND: Identifying individuals with a higher risk of developing severe coronavirus disease 2019 (COVID-19) outcomes will inform targeted and more intensive clinical monitoring and management. To date, there is mixed evidence regarding the impact of preexisting autoimmune disease (AID) diagnosis and/or immunosuppressant (IS) exposure on developing severe COVID-19 outcomes. METHODS: A retrospective cohort of adults diagnosed with COVID-19 was created in the National COVID Cohort Collaborative enclave. Two outcomes, life-threatening disease and hospitalization, were evaluated by using logistic regression models with and without adjustment for demographics and comorbidities. RESULTS: Of the 2 453 799 adults diagnosed with COVID-19, 191 520 (7.81%) had a preexisting AID diagnosis and 278 095 (11.33%) had a preexisting IS exposure. Logistic regression models adjusted for demographics and comorbidities demonstrated that individuals with a preexisting AID (odds ratio [OR], 1.13; 95% confidence interval [CI]: 1.09-1.17; P < .001), IS exposure (OR, 1.27; 95% CI: 1.24-1.30; P < .001), or both (OR, 1.35; 95% CI: 1.29-1.40; P < .001) were more likely to have a life-threatening disease. These results were consistent when hospitalization was evaluated. A sensitivity analysis evaluating specific IS revealed that tumor necrosis factor inhibitors were protective against life-threatening disease (OR, 0.80; 95% CI: .66-.96; P = .017) and hospitalization (OR, 0.80; 95% CI: .73-.89; P < .001). CONCLUSIONS: Patients with preexisting AID, IS exposure, or both are more likely to have a life-threatening disease or hospitalization. These patients may thus require tailored monitoring and preventative measures to minimize negative consequences of COVID-19.

When registering a new pesticide, 90-day oral toxicity studies performed with both rodent and non-rodent species, typically rats and dogs, are part of a standard battery of animal tests required in most countries for human health risk assessment (RA). This analysis set out to determine the need for the 90-day dog study in RA by reviewing data from 195 pesticides evaluated by the US Environmental Protection Agency (USEPA) from 1998 through 2021. The dog study was used in RA for only 42 pesticides, mostly to set the point of departure (POD) for shorter-term non-dietary pesticide exposures. Dog no-observed-adverse-effect-levels (NOAELs) were lower than rat NOAELs in 90-day studies for 36 of the above 42 pesticides, suggesting that the dog was the more sensitive species. However, lower NOAELs may not necessarily correspond to greater sensitivity as factors such as dose spacing and/or allometric scaling need to be considered. Normalizing doses between rats and dogs explained the lower NOAELs in 22/36 pesticides, indicating that in those cases the dog was not more sensitive, and the comparable rat study could have been used instead for RA. For five of the remaining pesticides, other studies of appropriate duration besides the 90-day rat study were available that would have offered a similar level of protection if used to set PODs. In only nine cases could no alternative be found in the pesticide's database to use in place of the 90-day dog study for setting safe exposure levels or to identify unique hazards. The present analysis demonstrates that for most pesticide risk determinations the 90-day dog study provided no benefit beyond the rat or other available data.

INTRODUCTION: This study aims to retrospectively compare the efficacy and safety of subxiphoid and subcostal arch thoracoscopic resection (SR) and the median sternotomy (MS) for thymoma with myasthenia gravis (MG) via propensity-matched analysis. METHODS: We retrospectively analyzed 502 patients with thymoma and MG in Tangdu Hospital of the Fourth Military Medical University from December 2012 to December 2017. The patients were allocated to SR group (n = 424) and MS group (n = 78). Perioperative outcomes were compared between SR group and MS group by using propensity-matched analysis. RESULTS: All SR and MS operations were accomplished successfully. Most postoperative outcomes between the two groups showed no significant difference such as remission of MG and postoperative complication (P > 0.05). There were statistically significant differences between MS group and SR group in operation time [(116.3 ± 33.7) min versus (52.2 ± 31.3) min], intraoperative blood loss [(145.2 ± 26.7) mL versus (51.2 ± 10.3) mL], chest drainage duration (3.4 d versus 0 d), days of hospital-stay (5.2 d versus 2.7 d), patient satisfaction score (5.9 ± 2.3 versus 8.7 ± 1.2), the incidence of complications and pain scores, with all P values < 0.05. CONCLUSIONS: This study suggests that subxiphoid and subcostal arch thoracoscopic resection is a less invasive procedure with good safety and feasibility as compared with median sternotomy for thymoma with myasthenia gravis.

BACKGROUND: Whether endoscopic submucosal dissection (ESD) applies to undifferentiated-type early gastric cancer (UEGC) remains controversial. We aimed to analyze the risk factors for lymph node metastasis (LNM) in UEGC and evaluate the feasibility of ESD. METHODS: This study included 346 patients with UEGC who underwent curative gastrectomy between January 2014 and December 2021. Univariate and multivariate analyses of the correlation between clinicopathological features and LNM were conducted, and the risk factors for exceeding the expanded ESD indications were evaluated. RESULTS: The overall LNM rate in UEGC was 19.94%. Among the preoperatively assessable factors, submucosal invasion (odds ratio [OR] = 4.77, 95% confidence interval [CI]: 2.14-10.66) and > 2 cm(OR = 2.49, 95% CI: 1.20-5.15) were independent risk factors for LNM, while postoperative independent risk factors were > 2 cm (OR = 3.35, 95% CI: 1.02-5.40) and lymphovascular invasion(OR = 13.21, 95% CI: 5.18-33.70). Patients who met the expanded indications had a low LNM risk (4.1%). Additionally, tumors located in the cardia (P = 0.03), non-elevated type (P < 0.01) were independent risk factors for exceeding the expanded indications in UEGC. CONCLUSIONS: ESD may be applicable for UEGC meeting the expanded indications, and preoperative evaluation should be cautious when the lesion is non-elevated type or located in the cardia. TRIAL REGISTRATION: Chinese Clinical Trial Registry (12/05/2022 ChiCTR2200059841 ).

BACKGROUND: Anal fistula is a common benign anorectal disease that often requires surgical intervention for effective treatment. In recent years, preoperative colonoscopy as a diagnostic tool in patients with anal fistula has garnered increasing attention due to its potential clinical application value. By investigating underlying inflammatory bowel disease (IBD), polyps, and other abnormalities, preoperative colonoscopy can offer insights to refine surgical strategies and improve patient outcomes. METHODS: This retrospective study focused on 1796 patients with various benign anorectal diseases who underwent preoperative intestinal endoscopy and met surgical criteria within the preceding three years at the First Affiliated Hospital of Guizhou University of Traditional Chinese Medicine. Among these patients, 949 diagnosed with anal fistula comprised group A, while 847 patients without anal fistula were assigned to group B for comparison. The investigation encompassed an analysis of general patient information, endoscopic findings, polyp histopathology, distribution of bowel inflammation sites, and results of inflammatory bowel disease assessments between the two patient cohorts. A subgroup analysis was also conducted on 2275 anal fistula patients with no surgical contraindications. This subgroup was categorized into Group A (949 patients who underwent preoperative intestinal endoscopy) and Group C (1326 patients who did not undergo preoperative colonoscopy). The study compared the rates of detecting endoscopic lesions and IBD-related findings between the two subgroups. RESULTS: The study initially confirmed the comparability of general patient information between groups A and B. Notably, the abnormal detection rate in group A was significantly higher than in group B (P < 0.01). In terms of endoscopic findings, the anal fistula group (group A) exhibited higher rates of detecting bowel inflammation, inflammatory bowel disease, and polyps compared to the non-anal fistula group (group B) (P < 0.05). The distribution of inflammation locations indicated higher detection rates in the terminal ileum, ileocecal region, and ascending colon for group A compared to group B (P < 0.05). Although the incidence of IBD in group A was higher than in group B, this difference did not reach statistical significance (P > 0.05). Subsequently, the analysis of the subgroup (groups A and C) revealed a significant disparity in intestinal endoscopic detection rates (P < 0.01) and statistically significant differences in detecting IBD (P < 0.05) and Crohn's disease (P < 0.05) between the two anal fistula subgroups. CONCLUSIONS: The findings of this study underscore the substantial clinical value of preoperative colonoscopy in the comprehensive evaluation of patients with anal fistula. Preoperative colonoscopy aids in ruling out localized perianal lesions caused by underlying inflammatory bowel disease, thereby mitigating the likelihood of missed diagnoses and enhancing treatment outcomes. This research highlights the importance of incorporating preoperative colonoscopy as a valuable diagnostic tool in managing anal fistula patients.

BACKGROUND: With the measles vaccine coverage rate gradually increasing, adult patients' epidemiological and clinical characteristics have changed. AIMS: To analyze the clinical characteristics of adult measles patients in Beijing Youan Hospital. METHODS: We retrospectively reviewed the electronic medical records of 818 patients diagnosed with measles at Beijing Youan Hospital between June 2010 and October 2021. We divided all hospitalized patients into two demographics groups, using 14 years of age as the cut-off. RESULTS: Of the adult inpatients, 110 (74.83%) were aged 20-40. There was an overall peak incidence in 2014, and yearly peaks came in April. Fever, cough, erythema, and Koplik's spots were present in 79.59%, 82.1%, 99.3%, and 59.8% of the adult group, respectively, compared to 75.26%, 92.0%, 99.9%, and 39.0% of the pediatric group. Decreased lymphocytes and hepatic impairment were common in adults. The adult group's median level of C-reactive protein was higher than that of the pediatric group (p < 0.05). The positive rate of measles antibody (IgM) detection was 64.6% in the adults and 78.8% in the pediatric group (p < 0.05). Of the adults, 46.9%, 8.8%, and 66% had pneumonia, gastroenteritis, and antibiotic use, compared to 89.6%, 2.7%, and 83.2% of the pediatric patients. The duration of symptoms before admission and the average length of hospital stay was approximately six days in both groups. CONCLUSIONS: Koplik's spots are more likely to be detected by clinicians in adult patients admitted to the hospital. Active surveillance is helpful for adults who are negative for IgM on admission. Although the proportion of adult measles patients with liver injury is high, the disease is generally mild. Measles significantly impacts peripheral blood lymphocytes in adults, but adults are at lower risk of concurrent pneumonia than the pediatric group. Clinicians need to pay attention to the appropriate use of antibiotics. Expanding the coverage of the measles vaccination in high-risk areas is beneficial for preventing measles in adults.

Aim: To investigate real-world chimeric antigen receptor (CAR) T-cell therapy treatment patterns. Patient & methods: Relapsed/refractory large B-cell lymphoma patients who received CAR T-cell therapy were identified. Patient characteristics, setting of CAR T-cell infusion, incidence of CAR T-cell therapy-associated adverse events and healthcare resource utilization were assessed. Results: Of 1175 patients, 83% were infused inpatient. Within three days postinfusion, inpatient-infused patients had a significantly higher risk of CAR T-associated adverse events (hazard ratio: 2.67; 95% CI: 2.09-3.42) compared with outpatient-infused patients. By day 30, 67% of outpatient-infused patients were hospitalized at least once. Conclusion: These findings suggest that physicians were able to select lower-risk patients for outpatient infusion, but postinfusion hospitalizations still occur.
This study tracks outcomes in patients with relapsed/refractory large B-cell lymphoma who received chimeric antigen receptor (CAR) T-cell therapy between 2017 and 2020. The authors used the Anlitiks All-Payor Claims (AAPC) database, which includes insurance claims of patients covered through Medicare, Medicaid or commercial insurance plans. AAPC includes over 80% of insured patients in the USA healthcare system. The study describes where patients received CAR T-cell therapy (inpatient/outpatient), rates of adverse events potentially related to CAR T-cell treatment and how much healthcare the patients received. In the 3 days after receiving CAR T-cell therapy, rates of CAR T-associated adverse events were significantly higher in patients who received CAR T-cell therapy in the inpatient setting, compared with outpatients. The findings suggest that lower-risk patients may receive CAR T-cell therapy as outpatients, but that most outpatient-infused patients will still require inpatient care.

BACKGROUND: The zoonotic hookworms Ancylostoma caninum and Uncinaria stenocephala are widespread soil-transmitted helminths in dogs in Europe. Given the veterinary and public health importance of hookworms in dogs and the recent changes in the molecular epidemiology of some species, there is a need to continuously monitor the epidemiological and molecular prevalence of these parasites also at the "local" level. The present study aimed to update the epidemiological scenario of hookworm infections in both owned and stray dogs in southern Italy and to discriminate between different hookworm species (A. caninum and U. stenocephala) through molecular analyses. For this purpose, a retrospective analysis was performed over 10 years (2011-2021), including a total of 7008 owned dogs and 5642 stray dogs referred to our laboratory for copromicroscopic examinations. Moreover, 72 faecal samples, from dogs naturally infected by hookworms, were used to discriminate between A. caninum and U. stenocephala using two PCR protocols. Prior to molecular analyses, a subsample of 40/72 positive faecal samples was used for morphometric investigations on hookworm eggs. RESULTS: The results of the ten-year retrospective analysis (2011-2021) showed an overall prevalence of hookworm infection of 9.16%, specifically 5.1% in owned dogs and 14.2% in stray dogs. Logistic regression showed a significant association between positivity to hookworms and the variable "puppies" both in stray (13.84%; OR = 2.4) and owned (7.07%; OR = 2.2) dogs. The results of molecular analyses showed that positivity was confirmed only in 21/72 samples, specifically, 6 samples using protocol A and 19 with protocol B. Sequencing revealed 15 samples positive to U. stenocephala and 6 to A. caninum. CONCLUSIONS: The findings of this study showed a high prevalence of hookworm infections in dogs in southern Italy, updating the epidemiological scenario of the last decade. Moreover, the results of the study revealed the first identification of hookworm species in dogs in Italy by molecular studies, highlighting that U. stenocephala is more prevalent than A. caninum.

INTRODUCTION AND HYPOTHESIS: Vesicovaginal fistula (VVF) brings severe psychological, physiological, and social stress to patients, which seriously affects the quality of their sexual life. Traditional transvaginal repair surgery can cause vaginal shortening. Transferring the lateral free flap can maintain vaginal length. This study was carried out to investigate the clinical efficacy of the surgery of flap transfer coverage for treating VVF. METHODS: A retrospective analysis was performed on 37 patients diagnosed with VVF and repaired by flap transfer coverage in the Urogynecology department of the First Affiliated Hospital of Kunming Medical University from January 2018 to June 2021. All patients took a prone split leg position to repair VVF with the flap transfer covering method and a chart review was performed. RESULTS: Among the 37 patients, there were 34 cases of primary complete healing, and the success rate reached 91.89% without recurrence and complications. Three cases recurred with leakage of urine; cystoscopy showed that the fistula was significantly reduced, and all patients were cured after secondary repair by the same surgical method without complications. CONCLUSIONS: Flap transfer coverage is a safe and effective surgical method for repairing VVF. The prone split leg position can better increase exposure. The fistula being away from the incision suture is the key to the success of the operation. Transferring the fistula can effectively improve the cure rate of VVF. Transferring the lateral free flap can maintain vaginal length.
