RESUMEN
A multinational outbreak of nosocomial fusarium meningitis occurred among immunocompetent patients who had undergone surgery with epidural anesthesia in Mexico. The pathogen involved had a high predilection for the brain stem and vertebrobasilar arterial system and was associated with high mortality from vessel injury. Effective treatment options remain limited; in vitro susceptibility testing of the organism suggested that it is resistant to all currently approved antifungal medications in the United States. To highlight the severe complications associated with fusarium infection acquired in this manner, we report data, clinical courses, and outcomes from 13 patients in the outbreak who presented with symptoms after a median delay of 39 days.

BACKGROUND: The current fungal meningitis outbreak caused by contaminated epidural anesthesia with Fusarium solani among patients who underwent surgical procedures in Matamoros, Mexico remains a cause of concern. Its association with an increased susceptibility for cerebrovascular complications (CVC) has not been reported. This single-center study describes 3 patients with a unique pattern of CVC attributed to fungal meningitis. METHODS: A retrospective case series of patients diagnosed with fungal meningitis following surgical procedures under contaminated epidural anesthesia who developed a unique pattern of CVC during their hospitalization. RESULTS: Three female patients (mean age, 35 years) with CVC due to iatrogenic fungal meningitis were included. Positive Fungitell ß-D-glucan assay in cerebrospinal fluid was documented in all cases, and F. solani was confirmed by polymerase chain reaction in case 3. All cases were complicated by severe vertebrobasilar circulation vasculopathy and arterial dissections with resultant subarachnoid hemorrhage and intraventricular hemorrhage, ultimately leading to patients' death. CONCLUSIONS: The death toll from the ongoing fungal meningitis outbreak keeps rising, underscoring the need for early recognition and aggressive treatment. We highlight the risk for vertebrobasilar circulation CVC among these patients. The angioinvasive nature of F. solani is yet to be clarified; however, a clear pattern has been observed. Public health awareness should be raised and a strong response should be pursued.

OBJECTIVES: To determine all-cause in-hospital mortality associated with severe hypernatraemia and the causes, comorbidities, time to treatment, discharge destination and postdischarge mortality. DESIGN: Retrospective observational cohort study. PATIENTS: Severe hypernatraemia, (sodium concentration ≥ 155 mmol/L), at any time during a tertiary hospital admission in Melbourne, Australia, 1 January 2019 to 31 December 2019 (pre-COVID19). MEASUREMENTS: Deaths, Charlson Comorbidity Index (CCI), hypernatraemia causes, time to treatment, discharge destination. RESULTS: One hundred and one inpatients: 64 community-acquired, 37 hospital-acquired. In-hospital mortality was 38%, but cumulative mortality was 65% by 1 month after discharge, with only a minor further increase at 6 and 12 months. After adjusting for peak sodium concentration, the community acquired group had significantly reduced odds of in-hospital mortality (odds ratio 0.15, 95% confidence interval [0.04-0.54], p = .003). Iatrogenic factors were present in 57% (21/37) of the hospital-acquired group. Only 55% of all cases received active sodium directed treatment. Time to start treatment did not affect outcomes. High levels of comorbidity were present, median CCI (IQR) was 6 (5-8) in the community and 5 (4-7) in the hospital group. Dementia prevalence was higher in the community group, 66% (42/64) versus 19% (7/37) (p = .001). Infection was the most common precipitant with 52% (33/64) in the community and 32% (12/37) in the hospital group. Of the survivors, 32% who had been living independently required residential care after discharge. CONCLUSIONS: Mortality was high and loss of independence in survivors common. To potentially improve outcomes, hypernatraemia-specific guidelines should be formulated and efforts made to reduce system and iatrogenic factors.

BACKGROUND AND OBJECTIVE: Other iatrogenic immunodeficiency-associated lymphoproliferative disorders (OIIA-LPD) are rare but well-known diseases that manifest during or after methotrexate (MTX) administration. Limited information is available on the clinical characteristics of OIIA-LPD of the lung because only a few cases have been reported. Thus, we aimed to assess the incidence and prognosis of patients with OIIA-LPD of the lung. METHODS: Patients with OIIA-LPD of the lung treated at our institution between January 2008 and July 2020 were retrospectively analysed. RESULTS: Among the 51 patients with OIIA-LPD, 16 (31.3%, 7 men, 9 women) had OIIA-LPD of the lung (median age, 69 [range, 63-82] years). Peripheral lesions were observed in 10 (62.5%), central lesions in two (12.5%), and both lesions in four (25.0%) patients. Nine of the 16 patients underwent bronchoscopic biopsy, seven were diagnosed (diagnostic yield, 77.8%) and, re-biopsy was performed in 2 patients. Eight (50.0%) patients had LPD and six (37.5%) had diffuse large B-cell lymphoma. In the 14 patients with confirmed treatment efficacy, the overall response rate to MTX withdrawal was 71.4%. However, chemotherapy was required in case of larger lesions (three patients). Death related to OIIA-LPD occurred in only one patient, and 11 of the 14 patients were alive during the study period (median follow-up time, 53.7 [range, 4.3-84.2] months). CONCLUSION: The incidence of OIIA-LPD of the lung is 31.3% and higher than that reported previously. The treatment effect of MTX withdrawal seems to be sufficient; however, in some cases, chemotherapy may be required from the beginning.

BACKGROUND: Physicians and associate (non-physician) clinicians conduct cesarean sections in Tanzania and Malawi. Urogenital fistulas may occur as complications of cesarean section. Location and circumstances can indicate iatrogenic origin as opposed to ischemic injury following prolonged, obstructed labor. METHODS: This retrospective review assessed the frequency of iatrogenic urogenital fistulas following cesarean sections conducted by either associate clinicians or physicians in Tanzania and Malawi. It focuses on 325 women with iatrogenic fistulas among 1290 women who had fistulas after cesarean birth in Tanzania and Malawi between 1994 and 2017. An equivalence test compared the proportion of iatrogenic fistulas after cesarean sections performed by associate clinicians and physicians (equivalence margin = 0.135). Logistic regression was used to model the occurrence of iatrogenic fistula after cesarean section, controlling for cadre, date, maternal age, previous abdominal surgery and parity. RESULTS: Associate clinicians attended 1119/1290 (86.7%) cesarean births leading to fistulas, while physicians attended 171/1290 (13.3%). Iatrogenic fistulas occurred in 275/1119 (24.6%) cesarean births by associate clinicians and in 50/171 (29.2%) cesarean births by physicians. The risk difference and 90% confidence interval were entirely contained within an equivalence margin of 13.5%, supporting a conclusion of equivalence between the two cadres. The odds of iatrogenic fistula after cesarean section were not statistically significantly different between associate clinicians and physicians (aOR 0.90; 95% CI 0.61-1.33). CONCLUSIONS: Associate clinicians appear equivalent to physicians performing cesarean sections in terms of iatrogenic fistula risk. Lower iatrogenic proportions for associate clinicians could reflect different caseloads. The occurrence of iatrogenic fistulas illustrates the importance of appropriate labor management and cesarean section decision-making, irrespective of health provider cadre. Given the noninferior performance and lower costs of employing associate clinicians, other countries with insufficient and/or unequally distributed health workforces could consider task-shifting cesarean sections to associate clinicians.

INTRODUCTION: The aims of this study were to investigate the independent risk factors associated with iatrogenic withdrawal syndrome in pediatric intensive care units (PICUs) and to establish receiver operator characteristic (ROC) curve to facilitate the diagnosis of iatrogenic withdrawal syndrome in clinical settings. METHODS: Pediatric patients who received analgesic and sedative medication at a tertiary hospital in the southern Zhejiang region of China between January 2016 and December 2022 were selected for the study. Clinical case data were retrospectively analyzed to gather information including age, gender, weight, total dose of analgesic and sedative medication, total treatment duration, average maintenance dose, and other relevant parameters. Medically induced withdrawal symptom scores were assessed using the Sophia Observation Scale for Withdrawal Symptoms (SOS). Univariate and multivariate logistic regression analyses were conducted on the above indicators to identify the risk factors for iatrogenic withdrawal, and an ROC curve was constructed. RESULTS: The study encompassed a total of 104 pediatric patients, comprising 47 patients in the SOS score ≥4 group and 57 patients in the SOS score ≤3 group. The incidence of iatrogenic withdrawal was 45.19%. Univariate analysis identified cumulative total dose of fentanyl, average daily dose of fentanyl, average daily dose of midazolam, and patient weight (p < 0.05) as factors associated with iatrogenic withdrawal syndrome. The logistic multiple regression analysis revealed that the average daily dose of fentanyl was an independent risk factor for the occurrence of iatrogenic withdrawal syndrome in critically ill children (p < 0.05). ROC curve analysis indicated an area under the curve of 0.711 (95% CI: 0.610-0.811) with sensitivity and specificity of 73.7% and 61.7%, respectively. CONCLUSION: The average daily maintenance dose of fentanyl holds significant clinical value in diagnosing and evaluating the prognosis of iatrogenic withdrawal syndrome and can provide a scientific foundation for enhancing sedative and analgesic management in clinical practice.

Iatrogenic ureteral injury (IUI) during colorectal surgery is a rare complication but related to a serious burden of morbidity. This comprehensive and systematic review aims to provide a critical overview of the most recent literature about IUI prevention techniques in colorectal surgery. We performed a comprehensive and systematic review of studies published from 2000 to 2022 and assessed the use of techniques for ureteral injury prevention and intraoperative localization. 26 publications were included, divided into stent-based (prophylactic/lighted ureteral stent and near-infrared fluorescent ureteral catheter [PUS/LUS/NIRFUC]) and fluorescent dye (FD) groups. Costs, the percentage and number of IUIs detected, reported limitations, complication rates and other outcome points were compared. The IUI incidence rate ranged from 0 to 1.9% (mean 0.5%) and 0 to 1.2% (mean 0.3%) in the PUS/LUS/NIRFUC and FD groups, respectively. The acute kidney injury (AKI) and urinary tact infection (UTI) incidence rate ranged from 0.4 to 32.6% and 0 to 17.3%, respectively, in the PUS/LUS/NIRFUC group and 0-15% and 0-6.3%, respectively, in the FD group. Many other complications were also compared and descriptively analyzed (length-of-stay, mortality, etc.). These techniques appear to be feasible and safe in select patients with a high risk of IUI, but the delineation of reliable guidelines for preventing IUI will require more randomized controlled trials.

INTRODUCTION: The treatment of closed humeral shaft fractures tends to be successful with functional bracing. Treatment failure due to iatrogenic conversion to an open fracture has not been described in the literature. We present a case series of patients that experienced open humeral shaft fractures after initially being treated with functional bracing for closed humeral shaft fractures and describe what factors are associated with this complication. MATERIALS AND METHODS: This was a retrospective case series performed at three level 1 trauma centers across North America. All nonoperatively treated humeral shaft fractures were reviewed from 2001 to 2023. Patients were included if they sustained a humeral shaft fracture, > 18 years old, were initially treated non-operatively with functional bracing which subsequently converted to an open fracture. Eight patients met inclusion criteria. All included patients were eventually treated with irrigation, debridement, and open reduction and internal fixation. Outcomes assessed included mortality rate, time until the fracture converted from closed to open, need for further surgery, and bony union. Descriptive statistics were used in analysis. RESULTS: The eight included patients on average were 65 ± 21.4 years old and had a body mass index (BMI) of 25.6 ± 5.2. Six patients were initially injured due to a fall. Time until the fractures became open on average was 5.2 ± 3.6 weeks. Three patients (37.5%) died within 1.8 ± 0.6 years after initial injury. The average Charlson Comorbidity Index (CCI) score was 4.5 ± 3.4. Three patients (37.5%) had dementia. Common characteristics among this cohort included a history of visual disturbances (50.0%), cerebrovascular accident (50.0%), smoking (50.0%), and alcohol abuse (50.0%). CONCLUSION: Conversion from a closed to open humeral shaft fracture after functional bracing is a potentially devastating complication. Physicians should be especially cognizant of patients with a low BMI, history of falling or visual disturbance, dementia, age ≥ 65, decreased sensorimotor protection, and significant smoking or alcohol history when choosing to use functional bracing as the final treatment modality. LEVEL OF EVIDENCE: IV.

OBJECTIVE: To determine the impact of the COVID-19 pandemic on hospital-acquired pressure injury (HAPI) rates and composition of HAPI stages among hospitalized patients across the US. METHODS: Using encounter-level data from a nationwide healthcare insurance claims database, the authors conducted a retrospective cohort study and an interrupted time-series analysis to determine HAPI rates among hospitalized patients within 90 days of admission before (January 2018 to February 2020) and after (March 2020 to December 2020) the onset of the COVID-19 pandemic. Of 3,418,438 adult patients assessed for inclusion in the study, 1,750,494 met the inclusion criteria. Outcomes measured included the presence of a HAPI within 90 days of admission and HAPI stage based on the International Classification of Diseases, 10th Revision diagnosis codes. RESULTS: The authors identified HAPIs in 59,175 episodes of care, representing 59,019 unique patients and corresponding to an overall HAPI rate of 2.65%. Baseline characteristics did not vary significantly across the two time periods. Further, HAPI rates were consistent across the time periods analyzed with no significant differences in rates following the onset of the pandemic (P = .303). Composition of HAPI stages remained consistent across the pandemic (unspecified, stages 1-4, Ps = .62, .80, .22, .23, and .52, respectively) except for a significant decrease in unstageable/deep tissue pressure injuries (-0.088%, P = .0134). CONCLUSIONS: Although hospital resources were strained at the peak of the COVID-19 pandemic, no differences were identified in HAPI rates among the study's cohort of privately insured patients.

OBJECTIVE: To investigate the incidence of iatrogenic skin injuries in neonates across 22 neonatal intensive care units (NICUs) in China. DESIGN: Prospective study. SETTING: 22 NICUs in China. PATIENTS: Infants admitted to NICU. INTERVENTIONS: None. MEASUREMENTS: The "Iatrogenic Skin Injuries Data Collection Form of infants" were used to collect the data during hospitalization. MAIN RESULTS: A total of 8126 neonates who were hospitalized in 22 tertiary hospitals across 15 provinces, cities, and autonomous regions of China between December 1, 2019 and January 31, 2020 were analyzed. Five hundred and twenty-one infants had iatrogenic skin injuries, including 250 with diaper dermatitis (47.98%), 70 with physicochemical factor-related skin lesions (PCFRSIs) (13.44%), 81 with medical device-related pressure injuries (MDRPIs) (15.55%), and 69 with medical adhesive-related skin injuries (MARSIs) (13.24%), accounting for 91% of the total number of iatrogenic injuries. Among these, diaper dermatitis was closely related to the skin and feeding status. Furthermore, the risk was higher among neonates who had skin damage upon admission or were already fully fed orally. The influencing factors of MDRPIs and MARSIs were similar. They were negatively associated with gestational age and birth weight, and were closely related to the presence of various tubes. CONCLUSIONS: Diaper dermatitis, PCFRSIs, MDRPIs, and MARSIs were the four common types of iatrogenic skin injuries in newborns. The various types of iatrogenic skin injuries were influenced by varying factors. Specialized nursing measurements can reduce the likelihood of these injuries.

Knowledge on the association between offspring birth weight and long-term risk of maternal cardiovascular disease (CVD) mortality is often based on firstborn infants without consideration of women's consecutive births. We studied long-term CVD mortality according to offspring birth weight patterns among women with spontaneous and iatrogenic term deliveries in Norway (1967-2020). We constructed birth weight quartiles (Qs) by combining standardized birth weight with gestational age in quartiles (Q1, Q2/Q3, and Q4) for the women's first 2 births. Mortality was estimated using Cox regression and expressed as hazard ratios (HRs) with 95% confidence intervals (CIs). Changes in offspring birth weight quartiles were associated with long-term maternal CVD mortality. Compared with women who had 2 term infants in Q2/Q3, women with a first offspring in Q2/Q3 and a second in Q1 had higher mortality risk (HR = 1.33, 95% CI: 1.18, 1.50), while risk was lower if the second offspring was in Q4 (HR = 0.78, 95% CI: 0.67, 0.91). The risk increase associated with having a first infant in Q1 was eliminated if the second offspring was in Q4 (HR = 0.99, 95% CI: 0.75, 1.31). These patterns were similar for women with iatrogenic and spontaneous deliveries. Inclusion of information from subsequent births revealed heterogeneity in maternal CVD mortality which was not captured when using only information based on the first offspring.

OBJECTIVES: Iatrogenic withdrawal syndrome (IWS) associated with opioid and sedative use for medical purposes has a reported high prevalence and associated morbidity. This study aimed to determine the prevalence, utilization, and characteristics of opioid and sedative weaning and IWS policies/protocols in the adult ICU population. DESIGN: International, multicenter, observational, point prevalence study. SETTING: Adult ICUs. PATIENTS: All patients aged 18 years and older in the ICU on the date of data collection who received parenteral opioids or sedatives in the previous 24 hours. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: ICUs selected 1 day for data collection between June 1 and September 30, 2021. Patient demographic data, opioid and sedative medication use, and weaning and IWS assessment data were collected for the previous 24 hours. The primary outcome was the proportion of patients weaned from opioids and sedatives using an institutional policy/protocol on the data collection day. There were 2,402 patients in 229 ICUs from 11 countries screened for opioid and sedative use; 1,506 (63%) patients received parenteral opioids, and/or sedatives in the previous 24 hours. There were 90 (39%) ICUs with a weaning policy/protocol which was used in 176 (12%) patients, and 23 (10%) ICUs with an IWS policy/protocol which was used in 9 (0.6%) patients. The weaning policy/protocol for 47 (52%) ICUs did not define when to initiate weaning, and the policy/protocol for 24 (27%) ICUs did not specify the degree of weaning. A weaning policy/protocol was used in 34% (176/521) and IWS policy/protocol in 9% (9/97) of patients admitted to an ICU with such a policy/protocol. Among 485 patients eligible for weaning policy/protocol utilization based on duration of opioid/sedative use initiation criterion within individual ICU policies/protocols 176 (36%) had it used, and among 54 patients on opioids and/or sedatives ≥ 72 hours, 9 (17%) had an IWS policy/protocol used by the data collection day. CONCLUSIONS: This international observational study found that a small proportion of ICUs use policies/protocols for opioid and sedative weaning or IWS, and even when these policies/protocols are in place, they are implemented in a small percentage of patients.

BACKGROUND: For the past several decades, epidemiological studies originating from the United States have consistently reported increasing rates of preterm birth (PTB). Despite the implementation of several clinical and public health interventions to reduce PTB rates, it remains the leading cause of infant morbidity and mortality in the United States and around the world. OBJECTIVE: This study aimed to examine recent trends in preterm birth and its clinical subtypes by maternal race and ethnicity among singleton births. STUDY DESIGN: Kaiser Permanente Southern California electronic health records for all singleton births between 2009 and 2020 (n=427,698) were used to examine preterm birth trends and their subtypes (spontaneous and iatrogenic preterm births). Data on preterm labor triage extracted from electronic health records using natural language processing were used to define preterm birth subtypes. Maternal race and ethnicity are categorized as non-Hispanic White, non-Hispanic Black, Hispanic, and non-Hispanic Asian or Pacific Islander. Multiple logistic regression was used to quantify the linear trend for preterm birth and its subtypes. Racial and ethnic trends were further examined by considering statistical interactions and stratifications. RESULTS: From 2009 to 2020, the overall preterm birth rate decreased by 9.12% (from 8.04% to 7.31%; P<.001). The rates decreased by 19.29% among non-Hispanic Whites (from 7.23% to 5.83%; P<.001), 6.15% among Hispanics (from 7.82% to 7.34%; P=.036), and 12.60% among non-Hispanic Asian or Pacific Islanders (from 8.90% to 7.78%; P<.001), whereas a nonsignificantly increased preterm birth rate (8.45%) was observed among non-Hispanic Blacks (from 9.91% to 10.75%; P=.103). Between 2009 and 2020, overall spontaneous preterm birth rates decreased by 28.85% (from 5.75% to 4.09%; P<.001). However, overall iatrogenic preterm birth rates increased by 40.45% (from 2.29% to 3.22%; p<.001). Spontaneous preterm birth rates decreased by 34.73% among non-Hispanic Whites (from 5.44% to 3.55%; P<.001), 19.75% among non-Hispanic Blacks (from 6.82% to 5.47%; P<.001), 22.96% among Hispanics (from 5.55% to 4.28%; P<.001), and 28.19% among non-Hispanic Asian or Pacific Islanders (from 6.50% to 4.67%; P<.001). Iatrogenic preterm birth rates increased by 52.42% among non-Hispanic Whites (from 1.88% to 2.61%; P<.001), 107.89% among non-Hispanic Blacks (from 3.18% to 6.13%; P<.001), 46.88% among Hispanics (from 2.29% to 3.26%; P<.001), and 42.21% among non-Hispanic Asian or Pacific Islanders (from 2.45% to 3.44%; P<.001). CONCLUSION: The overall preterm birth rate decreased over time and was driven by a decrease in the spontaneous preterm birth rate. There is racial and ethnic variability in the rates of spontaneous preterm birth and iatrogenic preterm birth. The observed increase in iatrogenic preterm birth among all racial and ethnic groups, especially non-Hispanic Blacks, is disconcerting and needs further investigation.

OBJECTIVE: To assess the incidence of ureteric injuries, clinical value of prophylactic ureteric stenting and impact of intra- or postoperative detection of ureteric injuries in patients treated with gynaecological or colorectal surgery. METHODS: Multiple databases were searched for articles published before September 2021 according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement. Studies were deemed eligible if they evaluated the differences in the rate of ureteric injuries between laparoscopic and open surgery, prophylactic ureteric stenting or not, and those of final treatment success between intra- and postoperative detection in patients who underwent gynaecological or colorectal surgery. RESULTS: Overall, 46 studies were eligible for this meta-analysis. Compared to open surgery, laparoscopic hysterectomy was associated with a higher incidence of ureteric injuries (pooled odds ratio [OR] 2.12, 95% confidence interval [CI] 1.71-2.62), but there was no statistically significant difference in colectomy (pooled OR 0.89, 95% CI 0.77-1.03). Prophylactic ureteric stenting was associated with a lower incidence of ureteric injuries during gynaecological surgery (pooled OR 0.61, 95% CI 0.39-0.96). The number needed to perform ureteric stenting to prevent one ureteric injury was 224 in gynaecological surgery. On the other hand, prophylactic ureteric stenting did not reduce the risk of ureteric injuries during colorectal surgery. Intraoperative detection of a ureteric injury was associated with a lower rate of complication management failure compared to postoperative detection (pooled OR 0.22, 95% CI 0.12-0.41). CONCLUSIONS: Laparoscopic hysterectomy seems to be associated with a higher rate of ureteric injuries compared to an open approach. Prophylactic ureteric stenting seems to reduce this risk during gynaecological surgery. Intraoperative detection of a ureteric injury during abdominal/pelvic surgery improves outcomes, suggesting the need for awareness and proactive problem identification. Further well-designed studies assessing the candidates who are more likely to benefit from prophylactic ureteric stenting including cost analysis are needed.

OBJECTIVE: To describe the rates of and risk factors associated with iatrogenic and spontaneous preterm birth and the variation in rates between hospitals. DESIGN: Cohort study using electronic health records. SETTING: English National Health Service. POPULATION: Singleton births between 1 April 2015 and 31 March 2017. METHODS: Multivariable Poisson regression models were used to estimate adjusted risk ratios (adjRR) to measure association with maternal demographic and clinical risk factors. MAIN OUTCOME MEASURES: Preterm births (<37 weeks of gestation) were defined as iatrogenic or spontaneous according to mode of onset of labour. RESULTS: Of the births, 6.1% were preterm and of these, 52.8% were iatrogenic. The proportion of preterm births that were iatrogenic increased after 32 weeks. Both sub-groups were associated with previous preterm birth, extremes of maternal age, socio-economic deprivation and smoking. Iatrogenic preterm birth was associated with higher body mass index (BMI) (BMI >40 kg/m2 adjRR 1.59, 95% CI 1.50-1.69) and previous caesarean (adjRR 1.88, 95% CI 1.83-1.95). Spontaneous preterm birth was less common in women with a higher BMI (BMI >40 kg/m2 adjRR 0.77, 95% CI 0.70-0.84) and in women with a previous caesarean (adjRR 0.87, 95% CI 0.83-0.90). More variation between NHS hospital trusts was observed in rates of iatrogenic, compared with spontaneous, preterm births. CONCLUSIONS: Just over half of all preterm births resulted from iatrogenic intervention. Iatrogenic births have overlapping but different patterns of maternal demographic and clinical risk factors to spontaneous preterm births. Iatrogenic and spontaneous sub-groups should therefore be measured and monitored separately, as well as in aggregate, to facilitate different prevention strategies. This is feasible using routinely acquired hospital data.

AIM: The long-term urological sequelae after iatrogenic ureteral injury (IUI) during colorectal surgery are not clearly known. The aims of this work were to report the incidence of IUI and to analyse the long-term consequences of urological late complications and their impact on oncological results of IUI occurring during colorectal surgery through a French multicentric experience (GRECCAR group). METHOD: All the patients who presented with IUI during colorectal surgery between 2010 and 2019 were retrospectively included. Patients with ureteral involvement needing en bloc resection, delayed ureteral stricture or noncolorectal surgery were not considered. RESULTS: A total of 202 patients (93 men, mean age 63 ± 14 years) were identified in 29 centres, corresponding to 0.32% of colorectal surgeries (n = 63 562). Index colorectal surgery was mainly oncological (n = 130, 64%). IUI was diagnosed postoperatively in 112 patients (55%) after a mean delay of 11 ± 9 days. Intraoperative diagnosis of IUI was significantly associated with shorter length of stay (21 ± 22 days vs. 34 ± 22 days, p < 0.0001), lower rates of postoperative hydronephrosis (2% vs. 10%, p = 0.04), anastomotic complication (7% vs. 22.5%, p = 0.002) and thromboembolic event (0% vs. 6%, p = 0.02) than postoperative diagnosis of IUI. Delayed chemotherapy because of IUI was reported in 27% of patients. At the end of the follow-up [3 ± 2.6 years (1 month-13 years)], 72 patients presented with urological sequalae (36%). Six patients (3%) required a nephrectomy. CONCLUSION: IUI during colorectal surgery has few consequences for the patients if recognized early. Long-term urological sequelae can occur in a third of patients. IUI may affect oncological outcomes in colorectal surgery by delaying adjuvant chemotherapy, especially when the ureteral injury is not diagnosed peroperatively.

BACKGROUND: Proper analgosedation is a cornerstone in the treatment of critically ill patients in Pediatric Intensive Care Units (PICUs). Medications, such as fentanyl, morphine, and midazolam, are essential to safe and respectful care. The use of these medications over time may lead to side effects such as iatrogenic withdrawal syndrome (IWS) in the tapering phase. The aim of the study was to test an algorithm for tapering analgosedation to reduce the prevalence of IWS in two Norwegian PICUs at Oslo University Hospital. METHODS: A cohort of mechanically ventilated patients from newborn to 18 years with continuous infusions of opioids and benzodiazepines for 5 days or more were included consecutively from May 2016 to December 2021. A pre- and posttest design, with an intervention phase using an algorithm for tapering analgosedation after the pretest, was used. The ICU staffs were trained in using the algorithm after the pretest. The primary outcome was a reduction in IWS. The Withdrawal Assessment Tool-1 (WAT-1) was used to identify IWS. A WAT-1 score ≥3 indicates IWS. RESULTS: We included 80 children, 40 in the baseline group, and 40 in the intervention group. Age and diagnosis did not differ between the groups. The prevalence of IWS was 95% versus 52.5% in the baseline group versus the intervention group, and the peak WAT-1 median was 5.0 (IQR 4-6.8) versus 3.0 (IQR 2.0-6.0) (p = .012). Based on SUM WAT-1 ≥ 3, which describes the burden over time better, we demonstrated a reduction of IWS, from a median of 15.5 (IQR 8.25-39) to a median of 3 (IQR 0-20) (p = <.001). CONCLUSION: We suggest using an algorithm for tapering analgosedation in PICUs since the prevalence of IWS was significantly lower in the intervention group in our study.

PURPOSE: Bile duct injury (BDI) remains the most serious complication following cholecystectomy. However, the actual incidence of BDI in the Czech Republic remains unknown. Hence, we aimed to identify the incidence of major BDI requiring operative reconstruction after elective cholecystectomy in our region despite the prevailing modern 4 K Ultra HD laparoscopy and Critical View of Safety (CVS) standards implemented in daily surgical practice among the Czech population. METHODS: In the absence of a specific registry for BDI, we analysed data from The Czech National Patient Register of Reimbursed Healthcare Services, where all procedures are mandatorily recorded. We investigated 76,345 patients who were enrolled for at least a year and underwent elective cholecystectomy during the period from 2018-2021. In this cohort, we examined the incidence of major BDI following the reconstruction of the biliary tract and other complications. RESULTS: A total of 76,345 elective cholecystectomies were performed during the study period, and 186 major BDIs were registered (0.24%). Most elective cholecystectomies were performed laparoscopically (84.7%), with the remaining open (15.3%). The incidence of BDI was higher in the open surgery group (150 BDI/11700 cases/1.28%) than in laparoscopic cholecystectomy (36 BDI/64645 cases/0.06%). Furthermore, the total hospital stays with BDI after reconstruction was 13.6 days. However, the majority of laparoscopic elective cholecystectomies (57,914, 89.6%) were safe and standard procedures with no complications. CONCLUSION: Our study corroborates the findings of previous nationwide studies. Therefore, though laparoscopic cholecystectomy is reliable, the risks of BDI cannot be eliminated.

BACKGROUND: Maintenance of normothermia is an important quality metric in pediatric anesthesia. While inadvertent hypothermia is effectively prevented by forced-air warming, this therapeutic approach can lead to iatrogenic hyperthermia in young children. AIMS: To estimate the influence of external warming by forced air on the development of intraoperative hyperthermia in anesthetized children aged 6 years or younger. METHODS: We pooled data from two previous clinical studies. Primary outcome was the course of core temperature over time analyzed by a quadratic regression model. Secondary outcomes were the incidence of hyperthermia (body core temperature >38°C), the probability of hyperthermia over the duration of warming in relation to age and surface-area-to-weight ratio, respectively, analyzed by multiple logistic regression models. The influence of baseline temperature on hyperthermia was estimated using a Cox proportional hazards model. RESULTS: Two hundred children (55 female) with a median age of 2.1 [1st -3rd quartile 1-4.2] years were analyzed. Mean temperature increased by 0.43°C after 1 h, 0.64°C after 2 h, and reached a peak of 0.66°C at 147 min. Overall, 33 children were hyperthermic at at least one measurement point. The odds ratios of hyperthermia were 1.14 (95%-CI: 1.07-1.22) or 1.13 (95%-CI: 1.06-1.21) for every 10 min of warming therapy in a model with age or surface-area-to weight ratio (ceteris paribus), respectively. Odds ratio was 1.33 (95%-CI: 1.07-1.71) for a decrease of 1 year in age and 1.63 (95%-CI: 0.93-2.83) for an increase of 0.01 in the surface-to-weight-area ratio (ceteris paribus). An increase of 0.1°C in baseline temperature increased the hazard of becoming hyperthermic by a factor of 1.33 (95%-CI: 1.23-1.43). CONCLUSIONS: In children, external warming by forced-air needs to be closely monitored and adjusted in a timely manner to avoid iatrogenic hyperthermia especially during long procedures, in young age, higher surface-area-to-weight ratio, and higher baseline temperature.

In March 2023, 34 associated cases of iatrogenic botulism were detected in Germany (30 cases), Switzerland (two cases), Austria (one case), and France (one case). An alert was rapidly disseminated via European Union networks and communication platforms (Food- and Waterborne Diseases and Zoonoses Network, EpiPulse, Early Warning and Response System) and the International Health Regulation mechanism; the outbreak was investigated in a European collaboration. We traced sources of the botulism outbreak to treatment of weight loss in Türkiye, involving intragastric injections of botulinum neurotoxin. Cases were traced using a list of patients who had received this treatment. Laboratory investigations of the first 12 German cases confirmed nine cases. The application of innovative and highly sensitive endopeptidase assays was necessary to detect minute traces of botulinum neurotoxin in patient sera. The botulism notification requirement for physicians was essential to detect this outbreak in Germany. The surveillance case definition of botulism should be revisited and inclusion of cases of iatrogenic botulism should be considered as these cases might lack standard laboratory confirmation yet warrant public health action. Any potential risks associated with the use of botulinum neurotoxins in medical procedures need to be carefully balanced with the expected benefits of the procedure.
