Abstract
Late presentation of congenital diaphragmatic hernia (CDH) presents usually after the neonatal period and often misdiagnosed for other respiratory pathologies. It is crucial to differentiate late presentation of CDH from other potential causes of respiratory distress and gastrointestinal symptoms. Herein, we present 2 cases of delayed presentation of congenital diaphragmatic hernia in infants. Initially, both cases were managed as respiratory conditions in outpatient settings, with no significant improvement. The correct diagnosis was eventually made through radiological evaluation at our tertiary centre, leading to successful surgical management. Delayed presentation of CDH beyond the neonatal period is rare, owing to the wide spectrum of clinical manifestations. Early diagnosis and surgical management are crucial to reduce morbidity and mortality, making a high index of suspicion essential for timely intervention.

The impact of inter-cycle treatment delays on 5-year all-cause mortality in early-stage breast cancer: A retrospective cohort study. Eur J Cancer 2024; 210:114301. [PMID: 39216173 DOI: 10.1016/j.ejca.2024.114301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2024] [Revised: 08/02/2024] [Accepted: 08/19/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND Inter-cycle delays to chemotherapy are often required to manage drug toxicity. The impact of delays on mortality is poorly characterised. This retrospective cohort study examined the association of treatment delay with all-cause mortality in early-stage breast cancer. METHODS This real-world analytical study included adult women with stage 2 or 3 breast cancer receiving first-line (neo-)adjuvant chemotherapy between 01/01/2014 and 31/12/2015 in England. Inter-cycle delays > 7 days during the treatment period were calculated, and the association of treatment delay with 5-year all-cause mortality was investigated. Survival was compared between patients experiencing treatment delay and those completing treatment to schedule using landmark methodology and Kaplan-Meier (KM) estimator. Cox proportional hazards regression was used to investigate the impact of delay on survival, using inverse probability of treatment weighting to adjust for confounding variables. RESULTS 8567 patients were included. 17 % (1448) experienced inter-cycle delay > 7 days during the treatment period. 1120 (13 %) women had died at the end of the 5-year follow up period. Median follow-up time was 5.5 years. Survival probability was significantly lower in patients experiencing treatment delay by KM estimator analysis (p < 0.0001). Cox proportional hazards regression demonstrated a significant positive association between delay and 5-year all-cause mortality (HR 1.33 95 % CI 1.12-1.61, p < 0.001). CONCLUSIONS This is the largest study of its kind demonstrating an association between treatment delay and all-cause mortality. These findings support interventions to improve toxicity management allowing completion of chemotherapy to schedule where patients experience treatment delay due to treatment-related toxicity or hospital capacity pressures.

Abstract
BACKGROUND We aimed to determine the timeliness of rabies post-exposure prophylaxis (PEP) and the proportion of individuals with an adequate antibody response post-PEP among those attending the Belgian national reference center. METHODS Retrospective analysis of patient records who attended our center from 2018 to 2023. Delay was defined as rabies immunoglobulin (RIG) and vaccine initiation beyond 2 calendar days after exposure. Antibodies were measured by rapid fluorescent focus inhibition test (RFFIT) after PEP in high-risk exposures. A titer ≥0.5 IU/ml was considered adequate. RESULTS We reviewed 317 patient records. Among individuals with inland exposure (n = 103), 85 % timely received PEP. Among travelers exposed abroad (n = 214), administration of RIG and vaccine initiation were timely in 30 % and 50 % of cases, respectively. An adequate antibody response was detected in 99.5 % (195/196) individuals. CONCLUSION Substantial PEP delays among travelers were observed. The robust antibody responses suggest that routine serological follow-up is not necessary for all patients.

Abstract
PURPOSE Delay in initiating adjuvant chemotherapy (AC) after curative resection of colorectal cancer (CRC) has been reported to lead to poor prognosis, but few studies have looked at associated factors. This study aimed to identify risk factors for delay in initiating AC. METHODS Data from 200 consecutive patients who underwent curative resection and AC for stage III CRC between 2013 and 2018 were retrospectively collected and analyzed. RESULTS AC was initiated more than 8 weeks after surgery in 12.5% of patients (the delay group). Compared to those with no delay (the non-delay group), patients in the delay group had significantly higher rates of synchronous double cancers (2.3% vs. 16.0%, p = 0.001), preoperative bowel obstruction (10.3% vs. 32.0%, p = 0.003), laparotomy (56.0% vs. 80.0%, p = 0.02), concomitant resection (2.9% vs. 24.0%, p < 0.001), and postoperative complications (32.0% vs. 56.0%, p = 0.02), and a significantly longer length of hospital stay (median 12 vs. 30 days, p < 0.001). In multivariate analysis, synchronous double cancers (odds ratio 10.2, p = 0.008), preoperative bowel obstruction (odds ratio 4.6, p = 0.01), concomitant resection (odds ratio 5.2, p = 0.03), and postoperative complications of Clavien-Dindo grade ≥ IIIa (odds ratio 4.0, p = 0.03) were identified as independent risk factors for delay in initiating AC. CONCLUSION Careful preoperative treatment planning for CRC patients with synchronous double cancers, preoperative bowel obstruction, and concomitant resection, and management for postoperative complication are necessary to avoid delay in initiating AC.

Abstract
BACKGROUND The present study analyzes a cohort of consecutive patients with ST-segment elevation acute myocardial infarction (STEMI), evaluating the ischemia-reperfusion times from the perspective of gender differences (females versus males), with a long-term follow-up. METHODS Single-center analytical cohort study of patients with STEMI in a tertiary hospital, between January 2015 and December 2020. RESULTS A total of 2668 patients were included, 2002 (75%) men and 666 (25%) women. The time elapsed from the onset of symptoms to the opening of the artery was 197min (IQR 140-300) vs 220min (IQR 152-340), p=0.004 in men and women respectively. A delay in health care significantly impacts the occurrence of cardiovascular adverse events at follow-up, HR 1.34 [95%CI 1.06-1.70]; p=0.015. CONCLUSIONS Women took longer to go to health care services and had a longer delay both in the diagnosis of STEMI and in coronary reperfusion. It is imperative to emphasize the necessity of educating women about the recognition of ischemic heart disease symptoms, empowering them to raise early alarms and seek timely medical attention.

Abstract
Slot structure is the equilibrium result of market demand side and slot resource supply side, while slot parameters reflect the operational support capacity of the aviation system. Time parameters reflect the operational support capability of the aviation system. Time structure should not only reflect changes in market demand, but also meet the constraints of operational efficiency. Constructing a reasonable 18-24 h timetable profile for busy airports that meets normal expectations for declared capacity and seasonal scheduling is a challenge in civil aviation slot management. This study utilizes historical data on airport flights and weather conditions to establish a regression prediction model for the time structure using K-means clustering and partial least squares regression. Additionally, ensemble learning is employed to forecast flight delay levels. The findings demonstrate that random forest yields favorable results in regression and prediction tasks, allowing for the integration of upper (good weather) and lower (severse weather) limits of the time profile with delay predictions as time parameter intervals. Consequently, the flights falling within these intervals achieve an average delay level of less than 15 min which meets the expectations of normal flight.

Abstract
Hearing impairment is considered to be related to the damage of hair cells or synaptic terminals, which will cause varying degrees of hearing loss. Numerous studies have shown that cochlear implants can balance this damage. The human ear receives external acoustic signals mostly under complex conditions, and its biophysical mechanisms have important significance for reference in the design of cochlear implants. However, the relevant biophysical mechanisms have not yet been fully determined. Using the characteristics of special acoustoelectric conversion in piezoelectric ceramics, this paper integrates them into the traditional FitzHugh-Nagumo neuron circuit and proposes a comprehensive model with coupled auditory neurons. The model comprehensively considers the effects of synaptic coupling between neurons, information transmission delay, external noise stimulation, and internal chaotic current stimulation on the synchronization of membrane potential signals of two auditory neurons. The experimental results show that coupling strength, delay size, noise intensity, and chaotic current intensity all have a certain regulatory effect on synchronization stability. In particular, when auditory neurons are in a chaotic state, their impact on synchronization stability is sensitive. Numerical results provide a reference for exploring the biophysical mechanisms of auditory neurons. At the same time, we are committed to providing assistance in using sensors to monitor signals and repair hearing impairments.

Abstract
PURPOSE Time to surgery from admission is one of the few variables known to influence outcome after a hip fracture. We reviewed our hip fracture database to determine correlation between delays to surgery and mortality in our elderly hip fracture population. METHODS Data on all hip fracture patients admitted to a large district hospital were prospectively collected between January 1989 and August 2021. Time of the injury, time of admission and time of surgery were recorded. Patients over 60 years old with a hip fracture requiring operative management were included. Patients with pathological fractures, those managed conservatively, and patients delayed for medical reasons were excluded. Surgical timing categories were divided into; under 12 h, 12-24 h, 24-72 h and over 72 h. RESULTS Time from admission to surgery was recorded for 10,659 patients, of these time of fall was available for 10,346 patients. Mean age was 82.2 years (sd 8.39) for the cohort and 30 day mortality was 6.20%. Odds of 30-day mortality was 1.43 (CI 1.057-1.988, p = 0.025) for delay to surgery from admission of over 12 h compared to under 12 h. Odds ratios for 30-day mortality were not significant at any other time threshold. The odds of 30-day mortality for delay to surgery from time of fall were 1.550 (CI 1.026-2.459, p = 0.048) at the 12 h threshold. CONCLUSION This is the largest prospective study to date in elderly patients with hip fractures demonstrating a statistically significant increase in 30-day mortality with a delay to surgery over 12 h.

Abstract
In the current study, we investigated how long the effects of one single collaboration session continue to influence individual memory. Participants learned categorized word lists and prose passages individually, and then they were instructed to recall learned materials either collaboratively or individually. Following initial recall, participants completed an individual recall test after a delay of 5 min, 48 h, or 1 week. On the initial recall test, we found that collaboration reduced recall of correct items on both word lists and prose passages (collaborative inhibition), and that collaboration reduced false recall on both word lists and prose passages (error correction). However, on the subsequent individual memory test after a delay, the pattern of post collaborative effects differed across veridical and false recall. For both word lists and prose passages, post collaborative benefits on correct recall lasted 1 week. However, there were no lasting effects of error correction on subsequent false recall. These results suggest that the time course of post collaborative benefits can be long lasting, but they are selective to veridical recall. The results are explained by theories of reexposure and error correction.

Abstract
OBJECTIVE To evaluate association between time to initiation of disease modifying treatment (DMT) and outcomes in pediatric-onset Multiple Sclerosis (POMS). METHODS A retrospective analysis of children with POMS from two tertiary referral pediatric Neuroimmunology clinics. Outcome measures comprised annualized relapse rate (ARR), MRI lesion burden (T1, T2-FLAIR, and post-GAD contrast sequences), EDSS, and 25-ft walk duration at the latest follow-up visit. Univariate and multivariate analysis using linear and logistic regression models were used to assess associations between patient characteristics and outcomes. RESULTS In total, 68 patients were reviewed. More than half of patients were female (62 %) and 32 (47 %) were Hispanic/LatinX. Median age at diagnosis was 14.2 years (IQR: 11.0-16.5), and median duration from diagnosis to the latest follow-up was 2.5 years (IQR: 1.6-4.6). Sensory (29.4 %), brainstem (23.5 %), and pyramidal (19.1 %) symptoms were most common. Interferon beta (32.4 %), dimethyl fumarate (27.9 %) and rituximab (26.5 %) were the most frequently used first-line DMT. Patients had a median ARR of 0.5 (IQR: 0.08-0.84), and EDSS score of 1.0 (IQR: 0.0-2.0) at the most recent follow-up. Delayed DMT initiation correlated with higher ARR (R = 0.38, p = 0.0016) and longer 25-ft walk duration (R = 0.34, p = 0.0077). In multivariate analysis, delayed DMT remained a significant predictor of higher ARR (p = 0.002) and longer 25-ft walk duration (p = 0.047). Delayed DMT initiation and use of low/moderate efficacy DMT predicted GAD enhancing lesions at the latest follow-up (p = 0.004 and 0.019 respectively). CONCLUSION Delayed DMT initiation in POMS is linked to unfavorable outcomes, including higher ARR and longer 25-ft walk duration.

Abstract
OBJECTIVE To provide healthcare professional-friendly practical recommendations for early detection of cleft palate-related deformities in newborns and offer an overview of managing these high-prevalent congenital abnormalities. SOURCE OF DATA PubMed, SciELO, Lilacs, Cochrane, ScienceDirect, and Scopus databases were reviewed for cleft- and diagnosis-related studies. SUMMARY OF THE FINDINGS Unfortunately, the global prevalence of delayed detection of cleft palate-related deformities remains unacceptably high, with over a quarter of cleft palates missed at birth. This delayed identification causes physical and psychological distress for patients and families, including feeding challenges and weight faltering. To improve cleft management, it is essential to adopt routine detailed, in-depth intraoral examination immediately after birth. It is recommended not only to finger-assisted palpate the intraoral structures but also to visually inspect the oral cavity from gingiva to uvula using a wooden tongue depressor and light-assisted examination. With timely diagnosis and referral to specialized care, pediatricians, nurses, speech therapists, and plastic surgeons provide life-changing treatments, including health care maintenance, anticipatory guidance, feeding support, primary surgical reconstruction, and age- and condition-specific protocols. CONCLUSIONS Encouraging neonatologists and pediatricians, who are the first to examine newborns, to actively investigate the intraoral region for cleft palate-related deformities is instrumental in optimizing therapeutic approaches and prioritizing age-phases in treatment. Their crucial role in early detection and referral can lead to transformative outcomes, impacting not only the future of the newborns by facilitating functional integration into society but also yielding positive effects on families and the health system.

Abstract
Background This study evaluates whether there are ethnic differences in time to surgery in women with early-stage (1-3a) breast cancer in four NZ urban regions between 2000 and 2020 pre- and post- Faster Cancer Treatment (FCT) implementation, which was introduced to address inequities in cancer outcomes. Methods This retrospective analysis used Te Rēhita Mate Ūtaetae (Breast Cancer Foundation National Register), a prospectively maintained database of breast cancers from 2000 to 2020. Women with stage 3b, 3c, metastatic or bilateral cancers were excluded. Logistic regression models evaluated ethnic differences in time to surgery (≤31/>31 days as per FCT plan) with sequential adjustment for potential contributing factors (demographic, mode of diagnosis, tumour, treatment facility type and treatment). Subgroup analyses by pre- and post-FCT implementation date were undertaken. Findings Of the 16,365 women included, 74.1% were NZ European (NZE), 10.2% were Māori, 6.1% were Pacific, and 9.2% were Asian. Wāhine Māori (Māori women) and Pacific women were more likely to experience delays in surgery >31 days, compared to NZE (maximally adjusted OR: 1.18; 95% CI:1.05, 1.33 and OR:1.42; 95% CI:1.22, 1.65, respectively)-deprivation and treatment facility type contributed most to this. Wāhine Māori experienced delay in the public system only. The associations did not differ between the pre- and post- FCT periods. Interpretation Ethnic inequities exist with respect to time to surgery for women with early-stage breast cancer and these differences persist after FCT implementation.

Abstract
BACKGROUND It remains unclear today whether the poor prognosis of pancreatic ductal adenocarcinoma (PDAC) was further worsened by the COVID-19 pandemic and whether this may affect providers and patients, today. Hence, this study aimed to investigate the effect of COVID-19 on care delivery and outcomes of patients with PDAC in the United States. METHODS The National Cancer Database was queried for PDAC, between 2017 and 2020. Changes in the number of diagnoses and treatment patterns were compared annually for the entire cohort. Changes in surgical outcomes and median time from diagnosis to treatment were compared and analyzed. Chi-square, Mann-Whitney U, and Kruskal-Wallis tests were performed. RESULTS Of 127,613 patients with PDAC, PDAC diagnoses from 2017 (30,573) to 2019 (33,465) increased but decreased in 2020 (31,218). The number of patients receiving surgery or radiotherapy was stable between 2017 to 2019 (21.75% ± 0.05% and 13.9% ± 0.3%, respectively) but decreased in 2020 (20.7% and 12.4% respectively). Although patients received chemotherapy with increasing frequently from 2016 (60.7%) to 2019 (63.5%), this trend stopped in 2020 (63%). Of 27,490 patients undergoing surgery, the mean time from diagnosis to surgery increased from 2017 (34 days) to 2019 (56 days), with an increase in delay in 2020 (81 days). Moreover, patients who were tested for COVID-19, had a longer median time from diagnosis to surgery even if tested negative (COVID+, 140 days; COVID-, 112 days; P < .001). CONCLUSION Although the oncologic quality of PDAC surgery remained the same during the pandemic, not only did the pandemic lead to an underdiagnosis of PDAC and care delays, but even the suspicion of COVID-19 in patients with a negative test adversely affected their care.

Abstract
BACKGROUND This study investigates whether early clozapine use is associated with improved responses in different clinical domains, including positive and negative symptoms, functioning, and well-being. METHODS Data from 254 clozapine-treated patients at Cambridgeshire and Peterborough NHS Foundation Trust (CPFT) were analysed. Among them, 231 (90.9 %) had a diagnosis of schizophrenia, 21 (8.3 %) schizoaffective disorder, and 2 (0.8 %) had other diagnoses. The International Classification of Diseases-Mortality and Morbidity Statistics criteria (ICD-10) were employed (World Health Organization, 1992). The cohort was assessed using the positive and negative syndrome scale (PANSS), the Brief Negative Symptom Scale (BNSS), Global Assessment of Functioning Scale (GAF), and the short version of Warwick-Edinburgh Mental Well-being Scale (SWEMWBS). Logistic regression models (for positive and negative symptom remission) and linear regression (for functioning and well-being) were utilized to assess the influence of time to clozapine initiation (TCI), age at the first episode of psychosis (AFE), duration of clozapine treatment (DCT), and gender. RESULTS Early clozapine treatment (within the first three years after the first episode of psychosis) was associated with increased negative symptom remission (exp (B) = 0.38; p = 0.02) and higher functioning scores (β = -0.12, p = 0.046). However, no effect of time to clozapine initiation was found on positive symptom remission rates or well-being scores. CONCLUSIONS Initiating clozapine treatment within the first 3 years of the first episode of psychosis may lead to reduced severity of negative symptoms and improved functioning in clozapine-treated patients. The time to clozapine initiation did not influence its effect on positive symptom remission rates.

Abstract
The paper addresses the switching-like event-triggered control for uncertain networked control systems with time-varying delay under DoS attacks. First of all, to reduce the communication burden, a switching-like event-triggered mechanism is designed to automatically select the trigger condition according to whether the system is under DoS attacks, which have the advantage of reducing the number of data packets transmitted. Secondly, unlike the traditional assumption of time-varying delay, here it satisfies the condition that the probability is known, and combines the networked control systems to propose a novel time-delay system model, which can obtain a larger upper bound on the delay. Then, by using both the Lyapunov functional method and linear matrix inequality technique, we obtain sufficient conditions of uncertain networked control systems to achieve exponentially stable in the mean square sense. Furthermore, under the common limitations of the maximum continuous packet losses caused by the DoS attacks and delay, the stability criterion is derived, which can be used to estimate the communication parameters and security controller gain. Finally, through two simulation examples, the larger upper bound of time delay, less trigger times, faster convergence rate are obtained, which verify the validity of our theoretical analysis.

The impact of anticoagulant medications on fragility femur fracture care: The hip and femoral fracture anticoagulation surgical timing evaluation (HASTE) study. Injury 2024; 55:111451. [PMID: 38507942 DOI: 10.1016/j.injury.2024.111451] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/23/2023] [Revised: 01/17/2024] [Accepted: 02/24/2024] [Indexed: 03/22/2024]
Abstract
INTRODUCTION Due to their hypocoagulable state on presentation, anticoagulated patients with femoral fragility fractures typically experience delays to surgery. There are no large, multicentre studies previously carried out within the United Kingdom (UK) evaluating the impact of anticoagulant use in this patient population. This study aimed to evaluate the current epidemiology and compare the perioperative management of anticoagulated and non-anticoagulated femoral fragility fracture patients. METHODS Data was prospectively collected through a collaborative, multicentre approach involving hospitals across the United Kingdom. Femoral fragility fracture patients aged ≥60 years and admitted to hospital between 1st May to 31st July 2023 were included. Main outcomes under investigation included time to surgery, receipt of blood transfusion between admission and 48 h following surgery, length of stay, and 30-day mortality. These were assessed using multivariable linear and logistic regression, and Cox proportional hazards models. Only data from hospitals ≥90 % case ascertainment with reference to figures from the National Hip Fracture Database (NHFD) were analysed. RESULTS Data on 10,197 patients from 78 hospitals were analysed. 18.5 % of patients were taking anticoagulants. Compared to non-anticoagulated patients, time to surgery was longer by 7.59 h (95 %CI 4.83-10.36; p < 0.001). 42.41 % of anticoagulated patients received surgery within 36 h (OR 0.54, 95 %CI 0.48-0.60, p < 0.001). Differences in time to surgery were similar between countries however there was some variation across units. There were no differences in blood transfusion and length of stay between groups (OR 1.03, 95 %CI 0.88-1.22, p = 0.646 and 0.22 days, 95 %CI -0.45-0.89; p = 0.887 respectively). Mortality within 30 days of admission was higher in anticoagulated patients (HR 1.27, 95 %CI 1.03-1.57, p = 0.026). CONCLUSIONS Anticoagulated femoral fragility fracture patients comprise a substantial number of patients, and experience relatively longer delays to surgery with less than half receiving surgery within 36 h of admission. This may have resulted in their comparatively higher mortality rate. Inclusion of anticoagulation status in the minimum data set for the NHFD to enable routine auditing of performance, and development of a national guideline on the management of this growing and emerging patient group is likely to help standardise practice in this area and improve outcomes.

Abstract
Gallbladder cancer (GBC) is a lethal disease. Incidentally detected gallbladder cancer (IGBC) presents a unique opportunity for early management and better outcomes. We present the institutional experience of a high-volume tertiary care center in northern India. Retrospective analysis of a prospectively maintained database was performed and data of all IGBC patients between January 2014 to December 2021 was analyzed. There were 125 patients of IGBC among the 750 patients of GBC seen during the study period. Of these 125 patients, 72 (57.6%) patients were not eligible for surgery. Successful completion radical cholecystectomy (CRC) was possible in 37 (69.8%) of the 53 patients who underwent surgery. On univariate analysis, thickness of gallbladder wall 10 mm or more (p < 0.001, OR 19.0, 95% CI 4.58-78.76), pathological stage (p < 0.001, OR 5.8, 95% CI 2.45-14.98) and median delay of 16 weeks or more (p < 0.001, OR 17.0, 95% CI = 4.08-70.76), were associated with inoperability. However, on multivariate analysis only gallbladder wall thickness of 10 mm or more (p < 0.001, AOR 17.9, 95% CI 3.24-98.78) and median delay of 16 weeks or more (p < 0.001, AOR 32.33, 95% CI 6.05-172.66) remained significant. Median time to recurrence (TTR) and overall survival (OS) was not reached after a median follow up of 30 months in patients undergoing successful CRC. Successful outcomes of IGBC are dependent on several factors. Diligent workup of suspicious thickening before simple cholecystectomy for gallstone disease and timely referral of IGBC to tertiary care are the keystones for good outcomes.

Abstract
We reported four patients with coronavirus disease 2019 (COVID-19)-associated myelopathies, highlighting the delayed and atypical spinal cord magnetic resonance imaging (MRI) features and the literature review. All four patients were males, aged 37 to 72 years old. The latencies from COVID-19 to the onset of myelitis were 5, 15, 30, and 80 days. The initial symptoms were numbness and weakness of lower limbs in three cases, and back pain with weakness of lower limbs in one case. The peak symptoms included paraplegia, sphincter dysfunction, sensory disturbance level, and spastic gait. The EDSS scores were 7.5, 9.0, 9.0, and 7.5, respectively. Magnetic resonance imaging (MRI) showed delayed atypical spinal cord lesions at onset, i.e., two cases without lesions, one with linear spinal meningeal enhancement, and one with punctate lesions on T2-weighted imaging (T2WI). During the follow-up period, punctate, linear, and cloudy lesions in the lateral and posterior funiculus were seen on T2WI in the peak stage. The prominent features of spinal cord lesions were linear spinal meningeal enhancement, the mismatch of deteriorated clinical symptoms, and inapparent MRI findings. All four patients were left with an obvious disability, with two patients completely bedridden and two who could stand with support. This report highlights the recognition of COVID-19-associated myelopathy even months after initial infection, especially in patients with delayed and atypical spinal cord findings on MRI.

Association between TB delay and TB treatment outcomes in HIV-TB co-infected patients: a study based on the multilevel propensity score method. BMC Infect Dis 2024; 24:457. [PMID: 38689228 PMCID: PMC11061920 DOI: 10.1186/s12879-024-09328-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2024] [Accepted: 04/16/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND HIV-tuberculosis (HIV-TB) co-infection is a significant public health concern worldwide. TB delay, consisting of patient delay, diagnostic delay, treatment delay, increases the risk of adverse anti-TB treatment (ATT) outcomes. Except for individual level variables, differences in regional levels have been shown to impact the ATT outcomes. However, few studies appropriately considered possible individual and regional level confounding variables. In this study, we aimed to assess the association of TB delay on treatment outcomes in HIV-TB co-infected patients in Liangshan Yi Autonomous Prefecture (Liangshan Prefecture) of China, using a causal inference framework while taking into account individual and regional level factors. METHODS We conducted a study to analyze data from 2068 patients with HIV-TB co-infection in Liangshan Prefecture from 2019 to 2022. To address potential confounding bias, we used a causal directed acyclic graph (DAG) to select appropriate confounding variables. Further, we controlled for these confounders through multilevel propensity score and inverse probability weighting (IPW). RESULTS The successful rate of ATT for patients with HIV-TB co-infection in Liangshan Prefecture was 91.2%. Total delay (OR = 1.411, 95% CI: 1.015, 1.962), diagnostic delay (OR = 1.778, 95% CI: 1.261, 2.508), treatment delay (OR = 1.749, 95% CI: 1.146, 2.668) and health system delay (OR = 1.480 95% CI: (1.035, 2.118) were identified as risk factors for successful ATT outcome. Sensitivity analysis demonstrated the robustness of these findings. CONCLUSIONS HIV-TB co-infection prevention and control policy in Liangshan Prefecture should prioritize early treatment for diagnosed HIV-TB co-infected patients. It is urgent to improve the health system in Liangshan Prefecture to reduce delays in diagnosis and treatment.

Abstract
BACKGROUND Based on the present global burden of oral diseases, unmet dental needs affect a more significant population worldwide. It is characterised by the need for dental care but receiving delayed or no care. The contributing factors include lack of knowledge about oral health, its consequences, and the availability of dental services. We need to find out the scale of the problem of unmet dental needs for the south Indian population. Therefore, the objective was to determine the relationship between the presence of oral disease and the quality of life-related to oral health using the OHIP-14 tool. METHODS The unmet dental requirements of the south Indian population were determined using a cross-sectional questionnaire survey. Close-ended questions were used to obtain data from two investigators trained to record the answers from the patients. The data was collected using the OHIP-14 questionnaire, which consists of 14 items divided into seven domains with two questions each. Physical pain, psychological impairment, physical disability, psychological disability, social disability, and disability were all considered. An additional analysis of artificial neural network (ANN) was done. RESULTS The response rate was 100 per cent. N = 1029 people replied to the questionnaire about their unmet dental needs. N = 497 (48.3%) were men, whereas N = 532 (51.7%) were women. The average age was 31.7811.72. As their current occupation, most of the included subjects (60.1%) were students. The respondents had no known personal habits and a mixed diet (94.93%). The average BMI was 24.022.59 (14-30.9). OHIP was present in 62.3% of the population. The average OHIP-14 severity score was 10.97. (8.54). The severity and degree of unmet dental need were substantial (p0.01) due to pain in the mouth/teeth/gums, malocclusion, and gum bleeding. The most common OHIP-14 domains affected by unmet oral needs were psychological discomfort, psychological limitation, social limitation, and feeling handicapped. The analysis of ANN revealed that high OHIP scores were primarily attributed to dental caries, poor oral health, and dental aesthetics. CONCLUSION The severity and degree of unmet dental needs were significant among the south Indian population. The most common oral health status that impacted OHIP-14 domains were pain, malocclusion, and bleeding gums. These patients were significantly impacted by psychological discomfort and social limitations and felt handicapped.

Abstract
INTRODUCTION To compare the various perioperative outcomes in an urgent surgery setting among patients with proximal femur fracture (PFF) who received platelet aggregation inhibitors (PAIs) and those who did not. METHODS We retrospectively reviewed the data of 1,838 patients who underwent surgery for PFF between January 2011 and January 2021. We conducted 1:1 propensity-score matching and compared the perioperative outcomes, including operation time, postoperative complications, hospital stay, mortality, and variables related to bleeding risk (e.g., number of transfusion profiles, hemoglobin levels, and laboratory data, including coagulation battery). RESULTS Of the 492 patients who were treated with PAIs, 484 were 1:1 matched to the untreated control group. The PAI group showed shorter operation time than the matched control group (72.3 min for PAI vs. 77.7 min for control; P = 0.041), and the control group showed more pulmonary thromboembolism (0.2% for PAI vs 1.7% for control; P = 0.046) than the PAI group. The other complications and length of hospital stay, mortality rate, transfusion profile, and the laboratory test (except preoperative international normalized ratio, INR) showed no significant difference between the groups. Subgroup analyses of the patients treated with only aspirin (aspirin: 306, matched control: 306), only clopidogrel (clopidogrel: 100, matched control: 100), and others who were treated with dual anticoagulation (dual anticoagulation: 78, matched control: 78) showed no significant differences in perioperative outcomes among the groups. CONCLUSION The patients who were treated with PAI could undergo PFF surgery safely without delay, which led to no significant difference in operation time, postoperative complication risk, perioperative blood transfusion, and variables related to bleeding risk. Therefore, we believe that it is unnecessary to delay surgery for patients with PFF who receive PAI.

Abstract
INTRODUCTION The overall incidence of tuberculosis (TB) in France is low; thus, BCG vaccination is no longer mandatory. In French Guiana - a French overseas territory - BCG vaccination is strongly recommended because the incidence of TB is high in the context of mass immigration from endemic countries with low BCG vaccination rates. Thus, it is important to assess Bacillus Calmette-Guérin (BCG) vaccination coverage and its predictors. METHODS We used data from the 2014 French Guiana Yellow Fever survey, which was conducted by the Observatoire Régional de la Santé de Guyane. Demographic and immunization data from eligible children and their families were collected using a questionnaire. Children who had an immunization card and who were no older than 7 years of age at the time of the survey were eligible. The Coverage for BCG and other mandatory vaccines were estimated; the delay in BCG vaccination was also computed. Univariate and multivariate analyses identified predictors associated with BCG immunization and BCG delayed immunization (after 2 months of age). RESULTS AND CONCLUSION Overall, 469 children were eligible for this study. The total BCG coverage was 79.5 %, and the proportion of children vaccinated with delay was 50.7 %. The multivariate analysis indicated that BCVA was significantly greater among children younger than 3 years of age, whose household head was employed and whose education level was greater. None of the predictors were associated with the delay of BCG vaccination.

Abstract
BACKGROUND Current muscle-invasive bladder cancer (MIBC) guidelines recommend not delaying radical cystectomy (RC) >3 months after diagnosis as it decreases overall survival (OS). However, literature investigating the impact of delay in RC in patients who receive NAC is limited, especially on a population-based level. OBJECTIVE To investigate the association between time from diagnosis of MIBC to RC (TTRC) in patients with urothelial bladder cancer (UBC) treated with NAC and RC and 1) 2-year OS and 2) pathological lymph node status (pN+) in a population-based cohort. METHODS Patients were selected from the Netherlands Cancer Registry. The study included 237 patients with cT2-T4aN0M0 UBC, treated with NAC and RC between November 2017 and October 2019. Association between TTRC and OS was assessed using multivariable Cox regression analyses. Schoenfeld and Martingale residuals were used to investigate the proportional hazards assumption and whether a cut-off in the TTRC could be identified. Association between TTRC and pN+ was assessed using multivariable logistic regression analyses. RESULTS Median TTRC was 23 weeks (interquartile range (IQR) 19-26). 2-year OS was 67% (95%CI 59%-74%). Each week of delay in the TTRC was independently associated with 2-year OS (HR 1.06; P = 0.03) in the Cox regression analysis. The sensitivity analyses, defining TTRC as the time between last cycle of NAC and RC, revealed that each week of delay between NAC and RC was associated with 2-year OS (Hazard ratio (HR) 1.13; P < 0.0001), and with pN+ (Odds ratio (OR) 1.21; P = 0.01) in the Cox and logistic regression analyses, respectively. CONCLUSIONS A longer TTRC is associated with worse oncological outcomes in patients treated with NAC and RC.

Abstract
INTRODUCTION Prostate cancer is still the leading male cancer and the leading cause of cancer deaths in Nigeria, and other low- and middle-income countries (LMIC) in Sub-Saharan Africa. Early diagnosis is essential to ensuring prompt treatment and reducing morbidity and mortality. Reducing the waiting times for diagnosis and treatment is therefore important. AIMS AND OBJECTIVES To study prostate cancer management waiting times, to serve as a baseline in improving the quality of cancer care in the Nigerian populace. PATIENTS AND METHODS This was a ten-year retrospective study of waiting times of all histologically-confirmed prostate cancer patients seen at Alex-Ekwueme Federal Teaching Hospital, Abakaliki, Ebonyi State, Nigeria. Statistical analysis was done SPSS version 26. A P-value less than 0.05 was considered statistically significant. RESULTS A total of 189 patients presented with prostate cancer; however, 73 patients with complete data were analysed. The mean age of the patients was 71.48±8.16 years. The median duration of symptoms before presentation was 6 months. The mean total prostate-specific antigen was 82.08±54.9ng/mL. The mean duration between the first visit to the definitive diagnosis was 6.53±11.68 months with a median of 1 month. The median duration from visit to treatment was 3 months with a mean of 9.71±13.4 months. There were no associations between occupation, highest educational level, financial constraints, and the different waiting times studied (P>0.05). CONCLUSION The waiting times for prostate cancer management were unduly prolonged in this study; patient-related factors did not influence this wait. INTRODUCTION Le cancer de la prostate est toujours le principal cancer chez les hommes et la principale cause de décès par cancer au Nigéria et dans d'autres pays à revenu faible et intermédiaire (PFR) en Afrique subsaharienne. Un diagnostic précoce est essentiel pour garantir un traitement rapide et réduire la morbidité et la mortalité. Il est donc important de réduire les délais d'attente pour le diagnostic et le traitement. OBJECTIFS Étudier les délais d'attente dans la prise en charge du cancer de la prostate, afin de servir de référence pour améliorer la qualité des soins contre le cancer dans la population nigériane. PATIENTS ET MÉTHODES Il s'agit d'une étude rétrospective de dix ans sur les délais d'attente de tous les patients atteints de cancer de la prostate confirmé histologiquement et traités à l'hôpital universitaire fédéral Alex-Ekwueme, à Abakaliki, dans l'État d'Ebonyi, au Nigéria. L'analyse statistique a été réalisée avec la version 26 du logiciel SPSS. Une valeur de P inférieure à 0,05 a été considérée comme statistiquement significative. RÉSULTATS Un total de 189 patients ont présenté un cancer de la prostate ; cependant, seuls les 73 patients avec des données complètes ont été analysés. L'âge moyen des patients était de 71,48±8,16 ans. La durée médiane des symptômes avant la présentation était de 6 mois. La concentration moyenne d'antigène spécifique de la prostate (PSA) total était de 82,08±54,9 ng/mL. La durée moyenne entre la première visite et le diagnostic définitif était de 6,53±11,68 mois, avec une médiane de 1(1) mois. La durée médiane entre la visite et le traitement était de 3 mois, avec une moyenne de 9,71±13,4 mois. Aucune association n'a été observée entre l'occupation, le plus haut niveau d'éducation, les contraintes financières et les différents délais d'attente étudiés (P>0,05). CONCLUSION Les délais d'attente pour la prise en charge du cancer de la prostate étaient anormalement prolongés dans cette étude ; les facteurs liés au patient n'ont pas influencé cette attente.

Abstract
INTRODUCTION Being up-to-date with all recommended vaccines is needed to protect children from vaccine preventable diseases. Understanding vaccination patterns is needed to develop messaging and strategies to increase vaccination uptake and confidence. METHODS Data from the 2011 to 2021 National Immunization Surveys was used to assess trends and disparities in vaccination patterns, zero vaccination status, and up-to-date status of U.S. children by 19-35 months. RESULTS From 2011 to 2021, adherence to the recommended schedule using the stringent definition increased from 35.7 % to 52.2 % (p < 0.01), adherence to the alternate schedule decreased from 28.2 % to 15.1 % (p < 0.01), and proportion of children who were not up-to-date decreased from 49.0 % to 33.3 % (p < 0.01). However, the proportion of children who had zero vaccinations did not change from 2011 (0.9 %) to 2021 (0.9 %; p = 0.08). In 2021, children 19-23 months were less likely to follow the recommended schedule than children 24-29 months (49.2 % compared to 56.4 %, p < 0.01). Adherence to the recommended schedule among children 19-23 months decreased in 2021 compared to 2020 overall and for some subpopulations (e.g. those with non-Hispanic (NH) Black parents (33.2 % compared to 44.9 %, p < 0.01). Furthermore, it was lowest among children of NH Black parents living at or below the federal poverty level (31.2 %) compared to their respective NH White counterparts (43.6 %, p < 0.01). CONCLUSIONS While there were overall increases in adherence to the recommended schedule from 2011 to 2021, a sustained catch-up program is needed to prevent missed vaccinations and achieve equitable vaccination coverage for all children.
