Abstract
Backgrounds
Primary scrotal lipomas are benign fatty tumors that develop from adipocytes of the scrotum. The exact cause of their development is unknown. They are typically painless and may exhibit symptoms of heaviness and discomfort.

Case presentation
A 9-year-old boy presented with a painless scrotal mass that had been present since birth. The mass was located in the left hemiscrotum. Ultrasound showed an enlarged left testicle with an abnormal outline and heterogeneous texture. Magnetic resonance imaging demonstrated a mass arising from the left hemiscrotum with no invasion of the testis. Under general anesthesia and through a scrotal incision, the mass was excised. Histopathological examination revealed a lipoma.

Conclusion
Primary scrotal lipomas are benign lesions with an unclear pathogenesis. They are very uncommon in the pediatric age group. Ultrasound is the first-line modality for diagnosing lipomas; however, it may provide ambiguity. MRI provides a more accurate assessment of the mass. Surgical excision of the mass is the standard treatment for primary scrotal lipomas.

Abstract
Background
Urological complications are not uncommon among people living with HIV and are often the initial clinical manifestation of HIV and AIDS. These complications, when presenting with bothersome lower urinary tract symptoms (LUTS), can significantly impact the Quality of life (QoL) of affected individuals. We, therefore, conducted a study aiming at determining the prevalence of bothersome LUTS, identifying factors influencing the severity of these symptoms, and examining their influence on the QoL among people living with HIV on antiretroviral treatment (ART).

Methods
A cross-sectional study was conducted among randomly selected adult HIV-positive patients who attended the Care and Treatment Center at Muhimbili National Hospital, located in Dar es Salaam, Tanzania, from September 2021 to February 2022. Data was collected using a questionnaire that incorporated the American version of the International Prostate Symptom Score (IPSS). The IPSS was utilized to assess the severity of LUTS and their influence on the QoL. Descriptive statistics were used to summarize the results, and ordinal regression analysis was employed to assess the factors influencing the severity of LUTS.

Results
The prevalence of LUTS in the study population was 57.8%, with mild symptoms (mean IPSS 3.92 ± 1.92) being the most common manifestation. The mean age of the study participants who presented with LUTS was 47.89 ± 12.05 years, and the majority were females (55.6%). Factors that were significantly associated with increased severity of LUTS included male sex (OR 2.75; 95% CI 1.59–4.75; p < 0.001), age above 49 years (OR 3.02; 95% CI 1.49–6.16; p = 0.002), ART use for over 10 years (OR 3.03; 95% CI 0.9–6.10; p = 0.021), and HIV stage IV (OR 2.42; 95% CI 0.9–3.4; p = 0.047). The majority of the study participants reported an above-average QoL, with only 9.7% of them reporting unhappy-terrible experiences with urinary symptoms. However, a statistically significant (p < 0.001) inverse correlation between QoL and the severity of LUTS was observed.

Conclusions
In light of these findings, policymakers and healthcare providers should integrate routine assessment and management of LUTS into the care protocols tailored for these high-risk groups. This proactive approach holds the potential to enhance the QoL and overall welfare of people living with HIV.
Using linked administrative data to aid the handling of non-response and restore sample representativeness in cohort studies: the 1958 national child development study and hospital episode statistics data

AbstractBackgroundThere is growing interest in whether linked administrative data have the potential to aid analyses subject to missing data in cohort studies.MethodsUsing linked 1958 National Child Development Study (NCDS; British cohort born in 1958, n = 18,558) and Hospital Episode Statistics (HES) data, we applied a LASSO variable selection approach to identify HES variables which are predictive of non-response at the age 55 sweep of NCDS. We then included these variables as auxiliary variables in multiple imputation (MI) analyses to explore the extent to which they helped restore sample representativeness of the respondents together with the imputed non-respondents in terms of early life variables (father’s social class at birth, cognitive ability at age 7) and relative to external population benchmarks (educational qualifications and marital status at age 55).ResultsWe identified 10 HES variables that were predictive of non-response at age 55 in NCDS. For example, cohort members who had been treated for adult mental illness had more than 70% greater odds of bring non-respondents (odds ratio 1.73; 95% confidence interval 1.17, 2.51). Inclusion of these HES variables in MI analyses only helped to restore sample representativeness to a limited extent. Furthermore, there was essentially no additional gain in sample representativeness relative to analyses using only previously identified survey predictors of non-response (i.e. NCDS rather than HES variables).ConclusionsInclusion of HES variables only aided missing data handling in NCDS to a limited extent. However, these findings may not generalise to other analyses, cohorts or linked administrative datasets. This work provides a demonstration of the use of linked administrative data for the handling of missing cohort data which we hope will act as template for others.
Incidence and predictors of elevated postpartum alanine aminotransferase in chronic hepatitis B mothers: a prospective study protocol

Published: November 2023

Abstract
Background
The majority of HBeAg-positive mothers with chronic hepatitis B have high levels of viremia and inactive disease with normal alanine aminotransferase (ALT) during pregnancy. In addition, postpartum disease activation and ALT flare have been reported in the range of 15 − 35%. However, the current International Association Guidelines have not provided clear recommendations and a risk-stratified monitoring schedule. Furthermore, data are lacking on the definition of normal ALT in the postpartum period in mothers with chronic hepatitis B. The clinical features and ALT flare patterns in HBeAg-positive mothers versus HBeAg-negative mothers are not fully explored. Thus, we design a cohort study to investigate the aforementioned area and generate data to assist healthcare providers in better managing mothers with hepatitis B. We aim to assess the frequency of postpartum ALT flares and predictors for such events.

Method
This study is a single-center and prospective cohort study (n = 360) that consists of two groups of patients including HBsAg-positive mothers (n = 120) and healthy mothers without HBV infection (n = 240). In HBeAg-positive mothers, antiviral therapy during late pregnancy is permitted to prevent Mother-to-child transmission (MTCT) but discontinued at delivery if there is no further indication for the treatment. Mothers are enrolled at the gestational weeks of 12–24. After delivery, both mothers and their infants will be followed up until postpartum week 24. Clinical and laboratory data are collected every 4 weeks during the study except there are no follow-up visits at the postpartum weeks 16 and 20. The primary objective is the proportion of patients with postpartum ALT flares. The secondary objectives are independent risk factors during pregnancy for predicting postpartum ALT flares and the normal range of postpartum ALT levels in healthy mothers.

Discussion
The current study focuses on the incidence of postpartum ALT flares in mothers with chronic hepatitis B including subgroup analysis based on HBeAg status. The data will have several clinical implications, such as providing evidence for an appropriate monitoring schedule in CHB mothers after delivery. Further analyses on predictors of such events may assist clinicians in identifying mothers who might develop severe postpartum ALT flares. The data generated from healthy mothers have the potential to identify the patterns of ALT changes during pregnancy and postpartum, so we can gain a better understanding of the normal range of ALT in this subpopulation.

Longitudinal mediation effects of activity meaning on the association between activity performance and quality of life among older adults with disabilities
Authors: Chao Shiau-Fang , Su Chin-Yi , Chang Ming-Fang 
Published: November 2023

Abstract
Background
Physical limitations may hinder older adults with physical disabilities’ capability to perform various activities, which can affect their quality of life (QOL). Accomplishing meaningful activities may mitigate the impact of limited activity performance on their QOL. This longitudinal study aims to investigate how activity meaning mediates the relationship between activity performance and QOL among older adults with disabilities.

Methods
Data for this longitudinal study was collected from 813 community-dwelling older adults aged 60 and above who had physical disabilities, over a two year interval. Path analysis was used to examine the cross-sectional and longitudinal mediation effects from activity performance, through activity meaning, to QOL.

Results
At the same wave, high IADL performance or social activity performance, and high QOL was indirectly associated through high IADL meaning or social meaning. As for longitudinal association, high T1 IADL performance was associated with better T2 QOL through high T1 and T2 IADL meaning. Similarly, high T1 social activity performance also contributed to T2 QOL through high T1 and T2 social activity meaning. Additionally, social activity performance exhibited higher influence on QOL than that of IADL.

Conclusions
Both IADL and social activities have distinct impacts on the QOL of older adults with disabilities. To improve the current and future QOL of older adults with disabilities, professionals must prioritize their involvement in the most meaningful activities while being sensitive to and supportive of their preferences and valued lifestyles.
Chromosome microarray analysis combined with karyotype analysis is a powerful tool for the detection in pregnant women with high-risk indicators
Authors: Qian Guanhua , Cai Liuyun , Yao Hong , Dong Xiaojing 
Published: November 2023

Abstract
Background
Karyotype analysis and fluorescence in situ hybridization (FISH) are commonly used for prenatal diagnosis, however they have many disadvantages. Chromosome microarray analysis (CMA) has the potential to overcome these disadvantages. This study aimed to evaluate the clinical value of CMA in the diagnosis of fetal chromosomal anomalies in southwest of China.

Methods
A total of 3336 samples of amniotic fluid or umbilical cord blood from pregnant women with high-risk indicators at our center in southwest of China from June 2018 to January 2023 were included in the retrospective analysis. 3222 cases tested by CMA and karyotyping, 114 cases only tested by CMA.

Results
3336 samples divided into 2911 cases with single and 425 cases with multiple high-risk indicators. The aneuploidy and pathogenic/likely pathogenic copy number variations (CNVs) of 2911 cases with single high-risk indicator were 4.43% (129/2911) and 2.44% (71/2911) respectively; the aneuploidy and pathogenic/likely pathogenic CNVs of 425 cases with multiple high-risk indicators were 6.82% (29/425) and 2.12% (9/425) respectively. The rate of aneuploidy increased significantly with pregnancy age or NT value. The detection rate of aneuploidy on cases with AMA combined NT ≥ 2.5 mm was significantly higher than that in cases only with AMA (p < 0.001); the detection rate of aneuploidy and pathogenic/likely pathogenic CNVs in cases with AMA combined NIPT high-risk were higher than that in cases only with AMA (p < 0.001, p < 0.05).

Conclusions
The combined application of CMA and karyotyping were recommended in prenatal diagnosis for providing a scientific and accurate genetic diagnosis and improving the quality of prenatal genetic counseling.
Racial and ethnic disparities in the incidence, healthcare utilization, and outcomes of retained placenta among delivery hospitalizations in the United States, 2016–2019
Authors: Jiang Wen , Chen Wei , Li Dong 
Published: November 2023

Abstract
Background
Retained placenta is a concern during labor and delivery. However, recent data regarding the profiles of retained placenta are scarce, especially nationwide and in minority populations. This study aimed to investigate the recent incidence of retained placenta and its associated outcomes.

Methods
We retrospectively analyzed an American population-based data from the National Inpatient Sample (NIS) 2016–2019. The outcomes of interest included the incidence of retained placenta, in-hospital mortality, length of hospital stay, and hospitalization costs. We estimated the incidence for retained placenta overall and by racial and ethnic subgroups, utilizing survey weights standardized for each subgroup. Multivariable linear or logistic regression models were employed in our study to investigate the associations between retained placenta and the impact of in-hospital mortality, duration of stay, and hospitalization expenditures for the entire population and further stratified by race and ethnicity, adjusting for potential confounders.

Results
Of the 13,848,131 deliveries, there were 108,035 (or 0.78%) birthing persons were identified as having retained placentas. Over time, the incidence of retained placenta increased from 730 per 100,000 (0.73%) in 2016 to 856 per 100,000 (0.86%) in 2019. Native American mothers have the highest rate of retained placenta, with a prevalence almost twice that of the general population, reaching 1,434 cases per 100,000 (1.43%). After adjusting for confounding factors, Native American mothers were more likely to have retained placenta (odds ratio [OR], 1.56; 95% confidence interval [CI], 1.35–1.81), whereas Black (OR, 0.92; 95% CI, 0.88–0.97) and Hispanic mothers (OR, 0.84; 95% CI, 0.80–0.89) were significantly less likely to have retained placenta than White mothers. Furthermore, those who delivered with a retained placenta were significantly associated with higher in-hospital mortality, a longer duration of stay, and hospitalization expenditures, which were disproportionately varied by maternal race and ethnicity.

Conclusions
The incidence of retained placenta among people undergoing vaginal delivery is exhibiting an upward trend over time, with notable variations observed across different ethnic groups by unclear mechanisms. The ramifications of these findings have the potential to impact the clinical management of maternal health care and the creation of health policies, specifically in relation to the Native American birth population.
High expression of CDKN2A is associated with poor prognosis in colorectal cancer and may guide PD-1-mediated immunotherapy

Published: November 2023

Abstract
Background
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Immunotherapy targeting the programmed death protein 1(PD-1) and its ligand (PD-L1), is a promising treatment option for many cancers, but has exhibited poor therapeutic efficacy in CRC. This study aimed to identify and validate the prognostic value of immune-related genes and PD-1-associated genes for immunotherapy treatment of CRC.

Methods
An extensive analysis of prognostic immune-related DEGs and PD-1-related genes has highlighted CDKN2A as a vital overlapping gene. To further explore its expression in CRC and its prognostic value, we conducted qRT-PCR, Western blot experiments, and consulted various databases. Subsequently, we conducted gene expression analysis, survival and prognostic analysis, enrichment analysis, immune infiltration assessment, and TIDE analysis to assess the significance of CDKN2A.

Results
In CRC, CDKN2A was highly expressed compared to normal tissue. It was found that CDKN2A expression was related to clinicopathological features such as inflammation and tumor stage. Furthermore, a significant correlation was identified between CDKN2A and immune infiltration, specifically involving CD4 T cells, CD8 T cells, and macrophages. The analysis of the GSEA of CRC samples with high CDKN2A expression identified enrichment of genes involved in MYC target-v2 and metabolism pathways. Furthermore, UBE2I, CDK4, CDK6, TP53, and CCND1 were found to be significantly coexpressed with CDKN2A, suggesting a potential role that these gene play in CRC and immunotherapy.

Conclusions
Our study revealed that high CDKN2A expression in CRC is a potentially valuable prognostic biomarker, which may guide PD-1-mediated immunotherapy.

Authors: Han Bing , Kang Yanrong , Wang Haiji , Wang Jian , Shen Rong , Liu Shuai , Lu Lu , Sun Zhigang , Zhang Nan 
Published: November 2023

Abstract
Background
Endostar is a strong angiogenesis inhibitor that is effective in treating non-small cell lung cancer (NSCLC), but the effect of Endostar in the treatment of patients with EGFR-TKI-resistant NSCLC remains unclear. We evaluated the clinical efficacy and safety of Endostar in EGFR-mutant NSCLC patients resistant to EGFR inhibition treatment.

Methods
From January 1, 2016 to June 30, 2018, 68 patients were selected from the 4 institutions for the study. Patients with NSCLC received Endostar plus chemotherapy every 21-day cycle. Chemotherapy types included platinum-containing dual drugs and platinum-free single drugs. Endostar was administered by intermittent intravenous infusion or continuous microinfusion pump infusion. The overall response rate (ORR), disease control rate (DCR) and adverse events were analyzed. Survival of patients was also evaluated.

Results
For all patients, the median progression-free survival (PFS) was 2.8 months, and the median overall survival (OS) was 14.2 months. PFS and OS in the Endostar pump continuous group were better than those in the Endostar intravenous infusion group. The disease control rate (DCR) was 79.4%. A total of 28 (41.2%) patients experienced varying grades of adverse events during treatment. No treatment-associated deaths were observed. The grade 3 treatment-emergent adverse events (TEAEs) were myelosuppression, weakness, and nausea/vomiting.

Conclusions
Endostar was effective and well tolerated in advanced NSCLC patients. Endostar treatment showed promising survival results in EGFR-mutant NSCLC patients.

Authors: Zhang Sisi , Tian Jing , Wang Xinwei , Liu Chengxin 
Published: November 2023

Abstract
Background
Programmed death-ligand 1 (PD-L1) inhibitors has emerged as a first-line therapeutic strategy for advanced small cell lung cancer (SCLC), which can stimulate T-cell activation, thereby preventing tumor avoidance of immunologic surveillance, whereas, proton pump inhibitors (PPIs) can play an important role in regulating immune function. This study assessed whether the concomitantly use of PPIs affected outcomes of immunotherapy in advanced SCLC.

Methods
Data from advanced SCLC patients who firstly treated with PD-L1 inhibitors between July 2018 and February 2021 was retrospectively analyzed. The impact of concomitant medications (especially PPIs) on objective response rate, progression-free survival (PFS) and overall survival (OS) were evaluated.

Results
Of 208 patients, 101 received immunotherapy concomitant PPIs. The median PFS of patients receiving PPIs (6.6 months) were significantly shorter than those without PPIs (10.6 months), and so was OS. There was associated with a 74.9% increased risk of progression and 58.3% increased risk of death. Both first-line and post-first-line immunotherapy, patients treated PPIs had poorer PFS.

Conclusion
PPIs therapy has a negative impact on the clinical outcomes of advanced SCLC patients treated with PD-L1 inhibitors.
Analysis of the achievement of primary and secondary goals and influencing factors in single-rooted immature permanent teeth after regenerative endodontic procedures: a retrospective study
Authors: Jiang Xijun , Liu He 
Published: November 2023

Abstract
Objective
This study explored the achievement of primary and secondary goals and factors influencing their achievement in regenerative endodontic procedures (REPs) for immature permanent teeth.

Methods
Dental records of all patients who received REPs for immature permanent teeth at the Department of Pediatric Dentistry, Peking University School and Hospital of Stomatology between January 2012 and January 2023 were retrieved. The evaluation of the primary goal was based on medical and radiographic records. The achievement of the primary goal was defined as the absence of clinical signs and symptoms, such as pain, swelling, or sinus tract and the absence of periapical radiolucency, as assessed on postoperative periapical radiographs. The achievement of secondary goal represented increased root wall thickness and/or increased root length, that is, continued root development. Periapical radiographs before and after treatment were used to evaluate the achievement of the secondary goal. The secondary goal was required to be achieved alongside the achievement of primary goal.

Results
A total of 436 teeth (136 anterior and 300 posterior teeth) were included in this study, 96.1% of which demonstrated achievement of the primary goal. Signs of failure (17 teeth) included crown fracture and uncontrolled and recurrent periapical lesions. In addition, 77.8% of teeth demonstrated achievement of the secondary goal, and more than half of the teeth exhibited a complete root development. Evaluation factors included patients’ age, sex, tooth type, etiology, preoperative periapical lesion, duration of clinical signs and symptoms, follow-up period, and stage of root development. The achievement of the primary and secondary goals were significantly related to age and tooth type (p < 0.05).

Conclusions
Children with a younger initial visit age are more likely to achieve primary and secondary goals. Additionally, posterior teeth had an advantage over anterior teeth in achieving primary and secondary goals.
