Rapid Initiation of Antiretroviral Therapy Under the Treat-All Policy Reduces Loss to Follow-Up and Virological Failure in Routine Human Immunodeficiency Virus Care Settings in China: A Retrospective Cohort Study (2016-2022).

Following the World Health Organization's guidelines for rapid antiretroviral therapy (ART) initiation [≤7 days after human immunodeficiency virus (HIV) diagnosis], China implemented Treat-All in 2016 and has made significant efforts to provide timely ART since 2017. This study included newly diagnosed HIV adults from Tianjin, China, between 2016 and 2022. Our primary outcome was loss to follow-up (LTFU) at 12 months after enrollment. The secondary outcome was 12-month virological failure. The association between rapid ART and LTFU, as well as virological failure, was assessed via Cox regression and logistic regression. A total of 896 (19.1%) of 4688 participants received ART ≤7 days postdiagnosis. The rate of rapid ART has increased from 7.5% in 2016 to 33.3% by 2022. The rapid ART group had an LTFU rate of 3.3%, as opposed to 5.0% in the delayed group. The rapid ART group had a much reduced virological failure rate (0.6% vs. 1.8%). Rapid ART individuals had a reduced likelihood of LTFU [adjusted hazard ratio: 0.65, 95% confidence intervals (CI): 0.44-0.96] and virological failure (adjusted odds ratio: 0.35, 95% CI: 0.12-0.80). The real-world data indicated that rapid ART is practicable and beneficial for Chinese people with HIV, providing evidence for its widespread implementation and scaling up.

Low surgical weight associated with ETV failure in pediatric hydrocephalus patients.

The use of endoscopic third ventriculostomy (ETV) for treatment of pediatric hydrocephalus has higher failure rates in younger patients. Here we investigate the impact of select perioperative variables, specifically gestational age, chronological age, birth weight, and surgical weight, on ETV failure rates. A retrospective review was performed on patients treated with ETV - with or without choroid plexus cauterization (CPC) - from 2010 to 2021 at a large academic center. Analyses included Cox regression for independent predictors and Kaplan-Meier survival curves for time to-event outcomes. In total, 47 patients were treated with ETV; of these, 31 received adjunctive CPC. Overall, 66% of the cohort experienced ETV failure with a median failure of 36 days postoperatively. Patients aged < 6 months at time of surgery experienced 80% failure rate, and those > 6 months at time of surgery experienced a 41% failure rate. Univariate Cox regression analysis showed weight at the time of ETV surgery was significantly inversely associated with ETV failure with a hazard ratio of 0.92 (95% CI 0.82, 0.99). Multivariate analysis redemonstrated the inverse association of weight at time of surgery with ETV failure with hazard ratio of 0.76 (95% CI 0.60, 0.92), and sensitivity analysis showed < 4.9 kg as the optimal cutoff predicting ETV/CPC failure. Neither chronologic age nor gestational age were found to be significantly associated with ETV failure.In this study, younger patients experienced higher ETV failure rates, but multivariate regression found that weight was a more robust predictor of ETV failure than chronologic age or gestational age, with an optimal cutoff of 4.9 kg in our small cohort. Given the limited sample size, further study is needed to elucidate the independent role of weight as a peri-operative variable in determining ETV candidacy in young infants.

Association of blood eosinophils with corticosteroid treatment failure stratified by smoking status among inpatients with AECOPD.

BACKGROUND: Recent studies have suggested elevated blood eosinophils are independent predictors of response to corticosteroid therapy in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Smoking status has been shown to affect corticosteroid response. Whether the association between high blood eosinophils and corticosteroid treatment failure is modified by smoking has not been fully investigated so far. OBJECTIVES: This study aimed to assess whether the association between high blood eosinophils and corticosteroid treatment failure is modified by smoking. METHODS: We included 3402 inpatients with AECOPD treated with corticosteroids at Beijing Chao-Yang Hospital from July 2013 to June 2021. Blood eosinophil counts were measured within 24 hours of admission. An eosinophil percentage ≥2% was considered as high eosinophilic. Smokers in this study were defined as current or former smokers. Treatment failure was defined as a worsening of AECOPD that led to adverse clinical outcomes or required further treatment or an extended hospital stay or hospitalisation following the exacerbation. Multivariate-adjusted logistic models were used to estimate the OR and 95% CI associated with treatment failure. RESULTS: There were 958 (28.2%) treatment failure events occurring. Patients with high eosinophils had a lower risk of treatment failure (OR 0.74, 95% CI 0.63 to 0.87) than patients with low eosinophils. Compared with never smoking and low eosinophilic group, the ORs for treatment failure were 0.70 (95% CI 0.52 to 0.96) for never smoking and high eosinophilic group, 0.82 (95% CI 0.64 to 1.05) for smoking and low eosinophilic group and 0.62 (95% CI 0.47 to 0.81) for smoking and high eosinophilic group. Furthermore, there was no significant interaction between eosinophils and smoking status in relation to treatment failure (p for interaction=0.73). Similar results were obtained from multiple secondary outcomes and subgroup analyses. CONCLUSION: Elevated blood eosinophils are associated with a lower rate of corticosteroid treatment failure, regardless of smoking status. Smoking does not modify the association between blood eosinophil level and corticosteroid treatment failure among inpatients with AECOPD.

Factors associated with referrals for directly observed treatment and unsuccessful treatment.

To describe the characteristics of people indicated for directly observed treatment (DOT) in Spain, and the factors associated with unsuccessful treatment.This was a multicentre observational study based on a prospective follow-up of patients over 18 years old diagnosed with TB between 2006 and 2019 from the registry of the Programa Integrado de Investigación en Tuberculosis (PII-TB). Sociodemographic and clinical variables were collected. Adjusted odds ratios (aORs) were calculated for the indication of DOT and for having an unsuccessful treatment.A total of 7,883 patients were included. The indication of DOT was associated with being homeless (aOR 5.93, 95% CI 3.03-11.59), inactivity status (aOR 2.55, 95% CI 2.02-3.23), alcohol consumption (aOR 1.94, 95% CI 1.51-2.48), parenteral drug use (aOR 1.77, 95% CI 1.06-2.95) and HIV diagnosis (aOR 1.96, 95% CI 1.16-3.29). Unsuccessful treatment was associated with having an HIV diagnosis (aPR 2.31, 95% CI 1.31-4.08), having a worse clinical and radiological evolution (clinical progression: APR 15.59, 95% CI 8.21-29.60; radiological progression: aPR 12.84, 95% CI 6.46-25.52), need for hospitalisation (aPR 1.73, 95% CI 1.10-2.73), unsatisfactory tolerability (aPR 2.82, 95% CI 1.49-5.29), the existence of difficulties in understanding the prescribed treatment (aPR 1.92, 95% CI 1.21-3.06), as well as worse treatment satisfaction (aPR 7.27, 95% CI 4.32-12.24).The prioritisation of vulnerable populations is a key aspect to carry out the new Global Plan to End TB 2023-2030. In these groups DOT indication should be increased to ensure adherence and patient follow-up and outcomes..

Salvage prostate intensity modulated radiation therapy after cryotherapy failure.

Cryotherapy is an ablative therapy that can be used to treat localized prostate cancer. In case of recurrence, treatment options are not well-defined, and their outcomes are unknown. We therefore collected all patients treated with radiotherapy after cryotherapy for prostate cancer recurrence in Nantes (France) between 2012 and 2019. We identified ten patients. After a median follow-up of 5 years, two patients presented late grade 3 toxicities; one patient presented a grade 3 rectal hemorrhage, and one had a grade 3 hematuria. Two patients relapsed at 61 and 62 months, and three patients died of other causes. Radiotherapy to treat local prostate cancer recurrence after cryotherapy seems feasible and effective in local control. These results do not allow us to recommend this technique in current practice but are encouraging for the conduct of prospective trials.

Treatment Failure and Long-Term Prescription Risk for Guideline-Recommended Hypnotics in Japan.

Importance: Although insomnia guidelines recommend the use of several individual hypnotics, the most useful hypnotic for treating insomnia in a clinical setting remains unclear. Objective: To determine which guideline-recommended hypnotics have lower risks of monotherapy failure and which hypnotics have a higher risk of long-term prescription for insomnia treatment. Design, Setting, and Participants: This retrospective observational cohort study used data from the Japan Medical Data Center Claims Database from April 1, 2005, to March 31, 2021. Participants included adults whose first prescribed pharmaceutical treatment for insomnia was guideline-recommended hypnotic monotherapy. Data were analyzed from December 24, 2022, to September 26, 2023. Exposures: Suvorexant, ramelteon, eszopiclone, zolpidem, and triazolam monotherapy. Main Outcomes and Measures: The primary outcome was monotherapy failure, defined as a change in hypnotic or having an additional hypnotic prescribed for insomnia within 6 months of the first prescription of a guideline-recommended hypnotic monotherapy. The secondary outcome was monotherapy discontinuation, defined as no prescription of any hypnotic for 2 consecutive months within 6 months after prescribing a guideline-recommended hypnotic in patients for whom monotherapy did not fail. Monotherapy failure and discontinuation were compared using Cox proportional hazards and logistic regression models, respectively. Results: The study included 239 568 adults (median age, 45 [IQR, 34-55] years; 50.2% women) whose first prescription for insomnia was guideline-recommended hypnotic monotherapy. During the 6-month follow-up period, 24 778 patients (10.3%) experienced failure of monotherapy with a guideline-recommended hypnotic. In comparison with eszopiclone, there were more cases of monotherapy failure for ramelteon (adjusted hazard ratio [AHR], 1.23 [95% CI], 1.17-1.30; P < .001), fewer cases for zolpidem (AHR, 0.84 [95% CI, 0.81-0.87]; P < .001) and triazolam (AHR, 0.82 [95% CI, 0.78-0.87]; P < .001), and no significant difference between suvorexant and eszopiclone. Among those without monotherapy failure, monotherapy was discontinued in 84.6% of patients, with more discontinuations for ramelteon (adjusted odds ratio [AOR], 1.31 [95% CI, 1.24-1.40]; P < .001) and suvorexant (AOR, 1.20 [95% CI, 1.15-1.26]; P < .001) than for eszopiclone and no significant difference between zolpidem or triazolam and eszopiclone. Conclusions and Relevance: Due to uncontrolled confounding factors in this cohort study, no conclusions regarding the pharmacologic properties of guideline-recommended hypnotics can be drawn based on these results. Further studies accounting for confounding factors, including diagnoses of chronic vs acute insomnia disorder, insomnia and psychiatric symptom severity, and physician attitudes toward hypnotic prescription, are needed.

A nomogram for predicting the risk of treatment failure of roxadustat in peritoneal dialysis with renal anemia.

The determinants of roxadustat treatment failure in renal anemia remain elusive. This study sought to develop a nomogram for predicting the risk of treatment failure of roxadustat in peritoneal dialysis (PD) with renal anemia. A retrospective cohort analysis from January 1, 2019, to January 31, 2023, included 204 PD patients with renal anemia, stratified by attainment group (Hb ≥ 110 g/L, n = 103) or non-attainment (Hb < 110 g/L, n = 101) within 1 year treatment. Univariate and multivariate Cox proportional hazards regressions were employed to ascertain predictive factors and construct the nomogram. Nomogram efficacy was evaluated via C-index, time-dependent ROC, calibration plots, and decision curve analysis, with internal validation via tenfold cross-validation and 1000 bootstrap resampling iterations. The study identified PD duration, serum transferrin, cardiovascular comorbidities, and stains as significant predictors. The nomogram demonstrated moderate discrimination at 6 months (AUC: 0.717) and enhanced predictive accuracy at 12 months (AUC: 0.741). The predicted and actual risk probabilities were concordant, with clinical net benefits observed at six-month (8 to 53%) and twelve-month (27 to 84%) risk thresholds. This nomogram is a valuable tool for effectively predicting non-attainment risk and facilitating personalized management of renal anemia in PD patients treated with roxadustat.

The efficacy of machine learning models in forecasting treatment failure in thoracolumbar burst fractures treated with short-segment posterior spinal fixation.

BACKGROUND: Although short-segment posterior spinal fixation (SSPSF) has shown promising clinical outcomes in thoracolumbar burst fractures, the treatment may be prone to a relatively high failure rate. This study aimed to assess the effectiveness of machine learning models (MLMs) in predicting factors associated with treatment failure in thoracolumbar burst fractures treated with SSPSF. METHODS: A retrospective review of 332 consecutive patients with traumatic thoracolumbar burst fractures who underwent SSPSF at our institution between May 2016 and May 2023 was conducted. Patients were categorized into two groups based on treatment outcome (failure or non-failure). Potential risk factors for treatment failure were compared between the groups. Four MLMs, including random forest (RF), logistic regression (LR), support vector machine (SVM), and k-nearest neighborhood (k-NN), were employed to predict treatment failure. Additionally, LR and RF models were used to assess factors associated with treatment failure. RESULTS: Of the 332 included patients, 61.4% were male (n = 204), and treatment failure was observed in 44 patients (13.3%). Logistic regression analysis identified Load Sharing Classification (LSC) score, lack of index level instrumentation, and interpedicular distance (IPD) as factors associated with treatment failure (P < 0.05). All models demonstrated satisfactory performance. RF exhibited the highest accuracy in predicting treatment failure (accuracy = 0.948), followed by SVM (0.933), k-NN (0.927), and LR (0.917). Moreover, the RF model outperformed other models in terms of sensitivity and specificity (sensitivity = 0.863, specificity = 0.959). The area under the curve (AUC) for RF, LR, SVM, and k-NN was 0.911, 0.823, 0.844, and 0.877, respectively. CONCLUSIONS: This study demonstrated the utility of machine learning models in predicting treatment failure in thoracolumbar burst fractures treated with SSPSF. The findings support the potential of MLMs to predict treatment failure in this patient population, offering valuable prognostic information for early intervention and cost savings.

[Prognostic factors associated with failure of modular knee arthroplasty in oncologic patients]. / Factores pronósticos asociados al fracaso de la artroplastía modular de rodilla en pacientes oncológicos.

INTRODUCTION: reconstruction of large bone defects using modular knee arthroplasty (MKA) presents a significant challenge in terms of functionality. The objective of the present work was to identify the different prognostic factors associated with failure of MKA in cancer patients. MATERIAL AND METHODS: a retrospective cohort study was conducted, including patients with a diagnosis of musculoskeletal tumor in the distal femur or proximal tibia, who underwent MKA between January 1, 2010, and December 31, 2021. RESULTS: 49 patients were included, of which 25 (51.02%) were women and 24 (48.98%) men, with a mean age of 29.57 years. Of these, 14 (28.57%) patients experienced some type of MKA failure. The most frequent complication that led to failure was periprosthetic infection, observed in seven (14.29%) patients. Variables associated with MKA failure included biopsies performed outside our hospital (HR 3.2, 95% CI 1.4-6.4, p = 0.02), the length of the long axis of the tumor (HR 2.1, 95% CI 1.2-4.6, p = 0.01) and a prolonged surgical time (HR 3.37, 95% CI 1.1-8.6, p = 0.04). CONCLUSION: the most significant prognostic factors associated with MKA failure in our cohort were tumor size, prolonged surgical time, and performance of the diagnostic biopsy in a center not specialized in the management of this type of patient. These findings highlight the importance of considering these variables to improve outcomes in patients undergoing MKA.

INTRODUCCIÓN: la reconstrucción de grandes defectos óseos mediante artroplastía modular de rodilla (AMR) representa un desafío significativo en términos de funcionalidad. El objetivo del presente trabajo fue identificar los diferentes factores pronósticos asociados al fracaso de la AMR en pacientes oncológicos. MATERIAL Y MÉTODOS: se realizó un estudio de cohorte retrospectiva, incluyendo pacientes con diagnóstico de tumor musculoesquelético en el fémur distal o la tibia proximal, que fueron sometidos a AMR entre el 1 de Enero de 2010 y el 31 de Diciembre de 2021. RESULTADOS: se incluyeron 49 pacientes, de los cuales 25 (51.02%) eran mujeres y 24 (48.98%) hombres, con una edad media de 29.57 años. De éstos, 14 (28.57%) pacientes experimentaron algún tipo de fracaso de la AMR. La complicación más frecuente que condicionó el fracaso fue la infección periprotésica, observada en siete (14.29%) pacientes. Las variables asociadas con el fracaso de las AMR incluyeron biopsias realizadas fuera de nuestro hospital (HR 3.2, IC95% 1.4-6.4, p = 0.02), longitud del eje mayor del tumor (HR 2.1, IC95% 1.2-4.6, p = 0.01) y tiempo quirúrgico prolongado (HR 3.37, IC95% 1.1-8.6, p = 0.04). CONCLUSIÓN: los factores pronósticos asociados al fracaso de las AMR en nuestra cohorte fueron el tamaño del tumor, un tiempo quirúrgico prolongado y la realización de la biopsia diagnóstica en un centro no especializado en el manejo de este tipo de pacientes. Estos hallazgos resaltan la importancia de considerar estas variables en pacientes sometidos a AMR.

[Risk factors for the failure of ibuprofen treatment in preterm infants with hemodynamically significant patent ductus arteriosus]. / æœ‰è¡€æµåŠ¨åŠ›å­¦æ„ä¹‰çš„åŠ¨è„‰å¯¼ç®¡æœªé—­æ—©äº§å„¿å¸ƒæ´›èŠ¬æ²»ç–—å¤±è´¥çš„å±é™©å› ç´ åˆ†æž.

OBJECTIVES: To investigate the risk factors for the failure of ibuprofen treatment in preterm infants with hemodynamically significant patent ductus arteriosus (hsPDA). METHODS: A retrospective collection of clinical data was conducted on preterm infants with a gestational age of <34 weeks who were diagnosed with hsPDA and treated at the Department of Neonatology, Maternal and Child Health Hospital of Hubei Province, Tongji Medical College, Huazhong University of Science and Technology, from January 2018 to June 2023. The subjects were divided into two groups based on the treatment approach: the ibuprofen group (95 cases) and the ibuprofen plus surgery group (44 cases). The risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA were identified by binary logistic regression analysis. RESULTS: The binary logistic regression analysis revealed that an increased diameter of the ductus arteriosus, a resistance index (RI) value of the middle cerebral artery ≥0.80, and prolonged total invasive mechanical ventilation time were risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). Receiver operating characteristic curve analysis showed that a ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days had significant predictive value for the failure of ibuprofen treatment in preterm infants with hsPDA (P<0.05). The combined predictive value of these three factors was the highest, with an area under the curve of 0.843, a sensitivity of 86.5%, and a specificity of 75.0% (P<0.05). CONCLUSIONS: A ductus arteriosus diameter >2.85 mm, a middle cerebral artery RI value ≥0.80, and a total invasive mechanical ventilation time >16 days are risk factors for the failure of ibuprofen treatment in preterm infants with hsPDA, and they are of significant predictive value for the necessity of surgical treatment following the failure of ibuprofen treatment.

Acute diverticulitis with extraluminal air: is conservative treatment sufficient? A single-center retrospective study.

BACKGROUND: Acute diverticulitis with extraluminal air constitutes a heterogeneous condition whose management is controversial. The aims of this study are to report the failure rate of conservative treatment for diverticulitis with extraluminal air and to report risk factors of conservative treatment failure. METHODS: A retrospective study was performed from an institutional review board-approved database of patients admitted with acute diverticulitis with extraluminal air from 2015 to 2021 at a tertiary referral center. All patients managed for acute diverticulitis with covered perforation (without intraabdominal abscess) were included. The primary endpoint was failure of medical treatment, defined as a need for unplanned surgery or percutaneous drainage within 30 days after admission. RESULTS: Ninety-three patients (61% male, mean age 57 ± 17 years) were retrospectively included. Ten patients had failure of conservative treatment (11%). These patients were significantly older than 50 years (n = 9/10, 90% versus n = 47/83, 57%, p = 0.007), associated with cardiovascular disease (n = 6/10, 60% versus n = 10/83, 12%, p = 0.002), American Society of Anesthesiologists (ASA) score of 3-4 (n = 4/7, 57% versus 6/33, 18%, p = 0.05), under anticoagulant and antiplatelet (n = 6/10, 60% versus n = 11/83, 13%, p = 0.04) and steroid or immunosuppressive therapy (n = 3/10, 30% versus 5/83, 6%, p = 0.04), and with distant pneumoperitoneum location (n = 7/10, 70% versus n = 14/83, 17%, p = 0.001) compared with those with successful conservative treatment. On multivariate analysis, only distant pneumoperitoneum was an independent risk factor of failure (odds ratio (OR) 6.5, 95% confidence interval (CI) [2-21], p = 0.002). CONCLUSIONS: Conservative treatment with antibiotics for acute diverticulitis with extraluminal air is safe with a success rate of 89%. Patients with distant pneumoperitoneum should be carefully monitored.

Predictive role of ureteral wall thickness and patient characteristics in endoscopic treatment outcomes for ureteral stricture disease following stone surgery.

PURPOSE: To evaluate the role of certain radiological parameters and patient characteristics in predicting the success of endoscopic treatment in ureteral stricture disease. METHODS: Fifty one adult patients with ureteral stricture disease (< 1 cm) after developing due to upper ureteral stones with ureteroscopic laser disintegration were included and in addition to stone and patient parameters, radiological parameters including ureteral wall thickness (UWT) at the impacted stone site were also measured on computed tomography (CT) images. Patients were divided into two groups: Group 1: Patients with endoscopic treatment success and Group 2: Patients with endoscopic treatment failure. The possible relationship between the UWT values and other radiological parameter was comparatively evaluated. RESULTS: Mean UWT value assessed at the treated stone site was significantly higher in cases unresponsive to endoscopic treatment with values of 2.77 ± 1.03 mm and 4.25 ± 1.32 mm in Group 1 and 2 respectively. A cut off value 3.55 mm for UWT was found to be highly predictive for endoscopic treatment failure. CONCLUSIONS: Our current results indicated that assessment of UWT value at the obstructing stone could be helpful enough to predict the likelihood of failure following endoscopic management of strictures with high sensitivity and specificity. Evaluation of this particular parameter could let the endourologists to look for more rational treatment alternatives with necessary measures taken on time.

Systematic review and meta-analysis of the management of acute uncomplicated diverticulitis: time to change traditional practice.

BACKGROUND: To evaluate comparative outcomes of outpatient (OP) versus inpatient (IP) treatment and antibiotics (ABX) versus no antibiotics (NABX) approach in the treatment of uncomplicated (Hinchey grade 1a) acute diverticulitis. METHODS: A systematic online search was conducted using electronic databases. Comparative studies of OP versus IP treatment and ABX versus NABX approach in the treatment of Hinchey grade 1a acute diverticulitis were included. Primary outcome was recurrence of diverticulitis. Emergency and elective surgical resections, development of complicated diverticulitis, mortality rate, and length of hospital stay were the other evaluated secondary outcome parameters. RESULTS: The literature search identified twelve studies (n = 3,875) comparing NABX (n = 2,008) versus ABX (n = 1,867). The NABX group showed a lower disease recurrence rate and shorter length of hospital stay compared with the ABX group (P = 0.01) and (P = 0.004). No significant difference was observed in emergency resections (P = 0.33), elective resections (P = 0.73), development of complicated diverticulitis (P = 0.65), hospital re-admissions (P = 0.65) and 30-day mortality rate (P = 0.91). Twelve studies (n = 2,286) compared OP (n = 1,021) versus IP (n = 1,265) management of uncomplicated acute diverticulitis. The two groups were comparable for the following outcomes: treatment failure (P = 0.10), emergency surgical resection (P = 0.40), elective resection (P = 0.30), disease recurrence (P = 0.22), and mortality rate (P = 0.61). CONCLUSION: Observation-only treatment is feasible and safe in selected clinically stable patients with uncomplicated acute diverticulitis (Hinchey 1a classification). It may provide better outcomes including decreased length of hospital stay. Moreover, the OP approach in treating patients with Hinchey 1a acute diverticulitis is comparable to IP management. Future high-quality randomised controlled studies are needed to understand the outcomes of the NABX approach used in an OP setting in managing patients with uncomplicated acute diverticulitis.

A systematic review of failed endoscopic hemostasis for nonvariceal upper gastrointestinal bleeding.

BACKGROUND: Nonvariceal upper gastrointestinal bleeding (NVUGIB) is a surgical emergency, usually managed via endoscopy. Approximately 2% of patients will have another significant bleed after therapeutic endoscopy and may require either transarterial embolization (TAE) or surgery. In 2011, the National Institute for Health and Care Excellence guidelines recommended that TAE should be the preferred option offered in this setting. METHODS: This study aimed to conduct an appraisal of guidelines on NVUGIB using the Appraisal of Guidelines for Research and Evaluation II tool. A specific review of their recommendations on the management of adult patients with failed endoscopic hemostasis that required TAE or surgery was conducted. RESULTS: The quality of the guidelines was moderate; most could be recommended with changes. However, their recommendations regarding TAE vs surgery were widely heterogeneous. A closer review of the underpinning evidence showed that most studies were retrospective, with a small sample size and missing data. CONCLUSION: Because of the heterogeneity in evidence, the decision regarding TAE vs surgery requires further research. Deciding between these modalities is primarily based on TAE availability and patient comorbidities. However, surgery should not be dismissed as a key option after failed endoscopic hemostasis.

Predicting early endodontic treatment failure following primary root canal treatment.

BACKGROUND: Understanding when and why endodontic treatments fail could help clinicians make prognoses and thus improve treatment outcomes. This study was aimed to assess potential predictors of early endodontic treatment failure. We explored factors contributing to the failure of initial root canal treatment were explored, with a specific emphasis on evaluating the influence of the time elapsed since the initial treatment. METHODS: This retrospective cohort study enrolled 1262 patients who sought endodontic treatment at our department and 175 patients were included for analysis. Potential causes of endodontic treatment failure were investigated, such as inadequate obturation quality, inadequate coronal status, the presence of additional untreated canals, anatomical complexity, instrument separation, iatrogenic perforation, cracks, and endodontic-periodontal lesions. The patients were divided into "short-term" and "long-term" groups depending on the time that had passed since the initial treatment (i.e., < 5 and > 10 years, respectively). The causes of failure in the short-term and long-term group were analyzed and compared using logistic regression analyses. Subgroup analysis was performed according to the number of years since the initial treatment in the short-term group to further investigate the association between the time and cause of failure (i.e., < 1, 2, 3, and 4 years, respectively). RESULTS: Untreated additional canals were present in 21.7% of all cases, and in 36.9 and 6.4% of cases in the short-term and long-term groups, respectively. Multivariable analysis showed that the presence of untreated additional canals was significantly associated with short-term compared to long-term failure. Untreated additional canals were also associated with endodontic failure within 1, 2, 3, and 4 years. CONCLUSIONS: The presence of untreated additional canals was a predictor of endodontic failure within 5 years following initial root canal treatment. To optimize long-term prognosis, it is important to detect and treat all root canals during the initial treatment.

Endobronchial silicone spigot in prolonged air leaks: Nationwide study on outcomes and risk factors for treatment failure.

BACKGROUND: The endobronchial silicone spigot, also known as the endobronchial Watanabe spigot, is used in bronchoscopic interventions to manage prolonged pulmonary air leakage. However, the outcomes of this procedure have not been thoroughly investigated. METHODS: Using a Japanese national inpatient database from April 2014 to March 2022, we assessed the clinical characteristics and outcomes of all eligible patients who received the endobronchial spigot. We also investigated risk factors associated with treatment failure. Treatment failure was defined as in-hospital death or the need for surgery after bronchial occlusion. RESULTS: We analyzed data of 1095 patients who underwent bronchial occlusion using the endobronchial spigot. Among them, 252 patients (23.0%) died during hospitalization, and 403 patients (36.8%) experienced treatment failure. Factors associated with treatment failure included age between 85 and 94 years (odds ratio [OR] 1.83; 95% confidence intervals [CI], 1.04-3.21); male sex (OR 2.43; 95% CI, 1.44-4.11); low Barthel index score; comorbidities of interstitial pneumonia (OR 1.71; 95% CI, 1.18-2.48); antibiotics treatment (OR 1.45; 95% CI, 1.02-2.07); steroids treatment (OR 1.59; 95% CI, 1.07-2.36); and surgery prior to bronchial occlusion (OR 2.08; 95% CI, 1.29-3.35). In contrast, pleurodesis after bronchial occlusion (OR 0.49; 95% CI, 0.32-0.75), and admission to high-volume hospitals were inversely associated with treatment failure (OR 0.58; 95% CI, 0.37-0.90). CONCLUSIONS: The endobronchial Watanabe spigot could be a nonsurgical treatment option for patients with prolonged pulmonary air leaks. Our findings will help identify patients who may benefit from such bronchial interventions.

Impacts of armed conflicts on tuberculosis burden and treatment outcomes: a systematic review.

OBJECTIVES: This systematic review aimed to summarise existing literature on the impacts of armed conflicts on tuberculosis burden and treatment outcomes. DESIGN: A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. DATA SOURCES: PubMed, Web of Science, Cumulative Index to Nursing and Allied Health Literature Plus, Scopus, ScienceDirect, Embase and medRxiv. DATA EXTRACTION AND SYNTHESIS: Three reviewers independently screened, selected eligible studies and extracted data. A narrative review was undertaken to summarise the findings qualitatively. RESULTS: Eleven studies were included in this review, reporting on tuberculosis incidence rates, prevalence and treatment outcomes, including mortality. Overall, the impact of armed conflicts on case notifications was variable. Six studies reported overall increases in tuberculosis case notifications following the onset of conflicts, while three studies reported overall decreases in tuberculosis case notifications. Factors, including limited access to healthcare services, challenges in surveillance and laboratory confirmation, the destruction of health systems and incapacitating the healthcare workforce, contributed to a decrease in the number of notified cases. The higher tuberculosis notification in some of the studies could be attributed to the disruption of tuberculosis prevention and control programmes as well as increased socioeconomic deprivation, including malnutrition, mass migration, poor living conditions and overcrowding that are worsened during conflicts. Armed conflicts without effective interventions were associated with worse tuberculosis treatment outcomes, including lower proportions of people with treatment success and higher proportions of people with loss to follow-up, mortality and treatment failure. However, implementing various interventions in conflict settings (such as establishing a National Tuberculosis Control Programme) led to higher tuberculosis notification rates and treatment success. CONCLUSION: The impact of armed conflicts on tuberculosis notification is complex and is influenced by multiple factors. The findings of this review underscore the importance of concerted efforts to control tuberculosis in conflict settings using available resources.

The effects of flow settings during high-flow nasal cannula oxygen therapy for neonates and young children.

BACKGROUND: During neonatal and paediatric high-flow nasal cannula therapy, optimising the flow setting is crucial for favourable physiological and clinical outcomes. However, considerable variability exists in clinical practice regarding initial flows and subsequent adjustments for these patients. Our review aimed to summarise the impact of various flows during high-flow nasal cannula treatment in neonates and children. METHODS: Two investigators independently searched PubMed, Embase, Web of Science, Scopus and Cochrane for in vitro and in vivo studies published in English before 30 April 2023. Studies enrolling adults (≥18 years) or those using a single flow setting were excluded. Data extraction and risk of bias assessments were performed independently by two investigators. The study protocol was prospectively registered with PROSPERO (CRD42022345419). RESULTS: 38 406 studies were identified, with 44 included. In vitro studies explored flow settings' effects on airway pressures, humidity and carbon dioxide clearance; all were flow-dependent. Observational clinical studies consistently reported that higher flows led to increased pharyngeal pressure and potentially increased intrathoracic airway pressure (especially among neonates), improved oxygenation, and reduced respiratory rate and work of breathing up to a certain threshold. Three randomised controlled trials found no significant differences in treatment failure among different flow settings. Flow impacts exhibited significant heterogeneity among different patients. CONCLUSION: Individualising flow settings in neonates and young children requires consideration of the patient's peak inspiratory flow, respiratory rate, heart rate, tolerance, work of breathing and lung aeration for optimal care.

Risk factors for treatment failure in multidrug resistant tuberculosis in Tunisia: An analytic study.

INTRODUCTION-AIM: The emergence of multidrug resistant tuberculosis (MDR-TB) is a threat to global public health. The aim of our study was to determine risk factors for treatment failure in MDR-TB. METHODS: Retrospective study conducted between January 2000 and March 2019 including patients with MDR-TB. Characteristics of patients with therapeutic failure were compared to cured ones. Logistic regression analysis was used to identify risk factors for treatment failure. RESULTS: Our study included 140 patients aged of 42±13 years (18-80). Fifty-seven percent of patients had treatment success and 12% had treatment failure. In multivariate logistic regression analysis, treatment failure was associated with age over 45 years (OR=1.05; 95%CI, 1.024-7.736;p=0.014), primary education level and illiteracy (OR=5.022; 95%CI, 1.316-19.161;p=0,018), history of incarceration (OR=3.291; 95%CI, 1.291-21.083;p=0.016), undernutrition (OR=4.544; 95%CI, 2.304-54.231;p=0,027), extensive TB (OR=6.406; 95%CI, 1.761-23.922; p=0.038), initial high grade positive smears (OR=1.210; 95%CI, 1.187-32.657; p=0.045), positive smear culture at 90 days of treatment (OR=6.871, 95%CI, 3.824-23.541; p=0.003), poor adherence (OR=6.110; 95%CI, 2.740-12.450; p=0.021) and occurrence of psychiatric adverse events (OR=3.644 95%CI, 2.560- 27.268; p=0.041). CONCLUSION: Therapeutic education, nutritional and psychological support and close follow-up are strongly recommended to optimize the prognosis of MDR-TB.
