Meta-analysis on clinical efficacy of ringheaded thumbtack needle in the treatment of allergic rhinitis.

To evaluate the efficacy and safety of ringheaded thrumbtack needle in the treatment of allergic rhinitis (AR). Clinical studies about treatment of AR with ringheaded thrumbtack needle were searched from databases of CNKI, Wanfang, China Science and Technology Journal, China Biology Medicine disc, PubMed, Embase and Web of Science from their inception to November 2022. Two researchers independently screened the literature and collected related information. The total effective rate, visual analogue scale (VAS) for AR, rhinoconjunctivitis quality of life questionnaire (RQLQ), and recurrence rate were the main outcome indicators. Secondary outcome indicators included quantitative scores of symptoms and signs, 'quartering' symptom evaluation scale, etc. All the included studies were subjected to Meta-analysis using Stata software. A total of 22 clinical studies involving 1 491 participants were included. The results of Meta-analysis indicated that the total effective rate of ringheaded thrumbtack needle in the treatment of AR was higher than that of traditional Chinese and Western medicine ［RR=1.20, 95%CI (1.14, 1.26), P<0.001］, and recurrence rate is lower than conventional therapy ［OR=0.35, 95%CI (0.14, 0.89), P=0.027］. Moreover, The VAS score ［WMD=-1.30, 95%CI (-1.85, -0.75), P<0.001］ and RQLQ score ［WMD=-6.75, 95%CI (-12.74, -0.76), P=0.027］ of AR treated by ringheaded thrumbtack needle were lower than those of traditional Chinese and Western medicine. Ringheaded thrumbtack needle can improve the total effective rate, reduce the disease recurrence, and improve the symptoms of discomfort when AR outbreaks, and has no significant adverse reactions. However, the reliability is limited. Thus, it is still necessary to improve the level of evidence quality by including researches with large samples, rigorous design and international standards.

Infant Feeding for Persons Living With and at Risk for HIV in the United States: Clinical Report.

Pediatricians and pediatric health care professionals caring for infants born to people living with and at risk for HIV infection are likely to be involved in providing guidance on recommended infant feeding practices. Care team members need to be aware of the HIV transmission risk from breastfeeding and the recommendations for feeding infants with perinatal HIV exposure in the United States. The risk of HIV transmission via breastfeeding from a parent with HIV who is receiving antiretroviral treatment (ART) and is virally suppressed is estimated to be less than 1%. The American Academy of Pediatrics recommends that for people with HIV in the United States, avoidance of breastfeeding is the only infant feeding option with 0% risk of HIV transmission. However, people with HIV may express a desire to breastfeed, and pediatricians should be prepared to offer a family-centered, nonjudgmental, harm reduction approach to support people with HIV on ART with sustained viral suppression below 50 copies per mL who desire to breastfeed. Pediatric health care professionals who counsel people with HIV who are not on ART or who are on ART but without viral suppression should recommend against breastfeeding. Pediatric health care professionals should recommend HIV testing for all pregnant persons and HIV preexposure prophylaxis to pregnant or breastfeeding persons who test negative for HIV but are at high risk of HIV acquisition.

Long-term Health Outcomes of New Persistent Opioid Use After Gastrointestinal Cancer Surgery.

New persistent opioid use (NPOU) after surgery has been identified as a common complication. This study sought to assess the long-term health outcomes among patients who experienced NPOU after gastrointestinal (GI) cancer surgery. Patients who underwent surgery for hepato-pancreato-biliary and colorectal cancer between 2007 and 2019 were identified using the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database. Mixed-effect multivariable logistic regression and Cox proportional hazard models were used to estimate the risk of mortality and hospital visits related to falls, respiratory events, or pain symptoms. Among 15,456 patients who underwent GI cancer surgery, 967(6.6%) experienced NPOU. Notably, the patients at risk for the development of NPOU were those with a history of substance abuse (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.14-1.84), moderate social vulnerability (OR, 1.26; 95% CI, 1.06-1.50), an advanced disease stage (OR, 4.42; 95% CI, 3.51-5.82), or perioperative opioid use (OR, 3.07; 95% CI, 2.59-3.63. After control for competing risk factors, patients who experienced NPOU were more likely to visit a hospital for falls, respiratory events, or pain symptoms (OR, 1.45, 95% CI 1.18-1.78). Moreover, patients who experienced NPOU had a greater risk of death at 1year (hazard ratio [HR], 2.15; 95% CI, 1.74-2.66). Approximately 1 in 15 patients experienced NPOU after GI cancer surgery. NPOU was associated with an increased risk of subsequent hospital visits and higher mortality. Targeted interventions for individuals at higher risk for NPOU after surgery should be used to help mitigate the harmful effects of NPOU.

Analysis of the Trends and Influencing Factors for Postoperative Cough in Patients with Esophageal Cancer Based on Patient-Reported Outcomes.

Cough is a common symptom that affects patients' recovery and quality of life after esophagectomy. This study sought to investigate trends in postoperative cough and the factors that influence cough. A total of 208 of 225 patients were enrolled in this study. The Mandarin Chinese version of the Leicester Cough Questionnaire was administered the day before surgery and at three time points (1 week, 1 month, and 3 months) after esophagectomy to assess patient-reported outcomes. All patients' LCQ-MC scores after surgery were lower than presurgery (P < 0.05), with the lowest score found 1 week after esophagectomy. Factors associated with a cough 1 week after surgery included clinical stage of cancer (OR 0.782, 95% CI 0.647-0.944, P = 0.011), anastomotic position (OR 1.241, 95% CI 1.069-1.441, P = 0.005), duration of surgery (OR 0.759, 95% CI 0.577-0.998, P = 0.049), and subcarinal lymph node dissection (OR 0.682, 95% CI 0.563-0.825, P < 0.001). Factors associated with a cough one month after surgery included clinical stage (OR 0.782, 95% CI 0.650-0.940, P = 0.009), anastomotic position (OR 1.293, 95% CI 1.113-1.503, P = 0.001), and maintaining a semi-reclining position (OR 1.440, 95% CI 1.175-1.766, P < 0.001). Factors associated with a cough 3 months after surgery were clinical stage (OR 0.741, 95% CI 0.591-0.928, P = 0.009) and anastomotic position (OR 1.220, 95% CI 1.037-1.435, P = 0.016). This study showed that the factors influencing postoperative cough differed over time following esophagectomy. These results may warrant prospective intervention to better manage patients undergoing surgery for esophageal cancer to prevent postoperative cough.

Comparison of the sputum microbiome between patients with stable nontuberculous mycobacterial pulmonary disease and patients requiring treatment.

We evaluated whether the sputum bacterial microbiome differs between nontuberculous mycobacteria pulmonary disease (NTM-PD) patients with stable disease not requiring antibiotic treatment and those requiring antibiotics. We collected sputum samples from 21 clinically stable NTM-PD patients (stable group) and 14 NTM-PD patients needing antibiotic treatment (treatment group). We also obtained 13 follow-up samples from the stable group. We analyzed the 48 samples using 16S rRNA gene sequencing (V3-V4 region) and compared the groups. In the linear discriminant analysis effect size (LEfSe) analysis, the species Porphyromonas pasteri, Haemophilus parahaemolyticus, Prevotella nanceiensis, and Gemella haemolysans were significantly more prevalent in the sputum of the stable group compared to the treatment group. No taxa showed significant differences in alpha-/beta-diversity or LEfSe between the 21 baseline and 13 follow-up sputum samples in the stable group. In the stable group, the genus Bergeyella and species Prevotella oris were less common in patients who achieved spontaneous culture conversion (n = 9) compared to those with persistent NTM positivity (n = 12) (effect size 3.04, p = 0.039 for Bergeyella; effect size 3.64, p = 0.033 for P. oris). In the treatment group, H. parainfluenzae was more common in patients with treatment success (n = 7) than in treatment-refractory patients (n = 7) (effect size 4.74, p = 0.013). Our study identified distinct bacterial taxa in the sputum of NTM-PD patients based on disease status. These results suggest the presence of a microbial environment that helps maintain disease stability.

Disparities in quality of life among patients with breast cancer based on surgical methods: a cross-sectional prospective study.

To determine the impact of breast conservation on quality of life and identify treatment-related and other demographic factors associated with post-breast cancer treatment quality of life. A prospective study was conducted on 392 women who underwent breast cancer surgery at Hangzhou Cancer Hospital from January 1, 2013, to December 31, 2022. Operable breast cancer patients who had completed all treatments except endocrine therapy were included. Patients with tumor recurrence/metastasis, bilateral or male breast cancer, and other primary malignancies were excluded. After enrollment, patients were asked to complete the BREAST-Q scale, and their pathological and medical records were reviewed. Analysis of variance was used to compare the quality of life scores among the groups. Univariate and multivariate linear regression analyses were performed to identify independent factors associated with quality of life scores in different domains. Participants completed the BREAST-Q scale at a median of 4.6years after surgery. Quality of life scores varied based on the therapeutic strategy. Breast conservation has significant advantages over mastectomy in terms of breast satisfaction, psychosocial, and sexual well-being. Compared to oncoplastic breast-conserving surgery, mastectomy was independently associated with decreased breast satisfaction, psychosocial, and sexual well-being, while conventional breast-conserving surgery showed comparable outcomes to oncoplastic breast-conserving surgery in terms of these factors. Breast conservation leads to an improvement in quality of life compared to mastectomy. Oncoplastic breast-conserving surgery does not lead to a decrease in quality of life compared to conventional breast-conserving surgery and offers better outcomes compared to mastectomy.

Practice Patterns and Outcomes Among Surgical Oncology Fellowship Graduates Performing Complex Cancer Surgery in the United States Across Different Career Stages.

Practice patterns and potential quality differences among surgical oncology fellowship graduates relative to years of independent practice have not been defined. Medicare claims were used to identify patients who underwent esophagectomy, pancreatectomy, hepatectomy, or rectal resection for cancer between 2016 and 2021. Surgical oncology fellowship graduates were identified, and the association between years of independent practice, serious complications, and 90-day mortality was examined. Overall, 11,746 cancer operations (pancreatectomy [61.2%], hepatectomy [19.5%], rectal resection [13.7%], esophagectomy [5.6%]) were performed by 676 surgical oncology fellowship graduates (females: 17.7%). The operations were performed for 4147 patients (35.3%) by early-career surgeons (1-7 years), for 4104 patients (34.9%) by mid-career surgeons (8-14 years), and for 3495 patients (29.8%) by late-career surgeons (>15 years). The patients who had surgery by early-career surgeons were treated more frequently at a Midwestern (24.9% vs. 14.2%) than at a Northeastern institution (20.6% vs. 26.9%) compared with individuals treated by late-career surgeons (p < 0.05). Surgical oncologists had comparable risk-adjusted serious complications and 90-day mortality rates irrespective of career stage (early career [13.0% and 7.2%], mid-career [12.6% and 6.3%], late career [12.8% and 6.5%], respectively; all p > 0.05). Surgeon case-specific volume independently predicted serious complications across all career stages (high vs. low volume: early career [odds ratio {OR}, 0.80; 95% confidence interval {CI}, 0.65-0.98]; mid-career [OR, 0.81; 95% CI, 0.66-0.99]; late career [OR, 0.78; 95% CI, 0.62-0.97]). Among surgical oncology fellowship graduates performing complex cancer surgery, rates of serious complications and 90-day mortality were comparable between the early-career and mid/late-career stages. Individual surgeon case-specific volume was strongly associated with postoperative outcomes irrespective of years of independent practice or career stage.

Healthcare utilization and expenditures among patients with venous thromboembolism following gastrointestinal cancer surgery.

We sought to assess healthcare utilization and expenditures among patients who developed venous thromboembolism (VTE) after gastrointestinal cancer surgery. Patients who underwent surgery for esophageal, gastric, hepatic, biliary duct, pancreatic, and colorectal cancer between 2013 and 2020 were identified using the MarketScan database. Entropy balancing was performed to obtain a cohort that was well balanced relative to different clinical covariates. Generalized linear models were used to compare 1-year postdischarge costs among patients who did and did not develop a postoperative VTE. Among 20,253 individuals in the analytical cohort (esophagus [n=518 {2.6%}], stomach [n=970 {4.8%}], liver [n=608 {3.0%}], bile duct [n=294 {1.5%}], pancreas [n=1511 {7.5%}], colon [n=12,222 {60.3%}], and rectum [n=4130 {20.4%}]), 894 (4.4%) developed VTE. Overall, most patients were male (n=10,656 [52.6%]), aged between 55 and 64 years (n=10,372 [51.2%]), and were employed full time (n=11,408 [56.3%]). On multivariable analysis, VTE was associated with higher inpatient (mean difference [MD], $17,547; 95% CI, $15,141-$19,952), outpatient (MD, $8769; 95% CI, $7045-$10,491), and pharmacy (MD, $2811; 95% CI, $2509-$3113) expenditures (all P<.001). Furthermore, patients who developed VTE had higher out-of-pocket costs for inpatient (MD, $159; 95% CI, $66-$253) and pharmacy (MD, $122; 95% CI, $109-$136) services (all P<.001). Among privately insured patients aged <65 years, VTE was associated with increased healthcare utilization and expenditures during the first year after discharge.

Kidney-sparing surgery has equivalent oncological outcomes to radical nephroureterectomy for ureteral urothelial carcinoma.

Kidney-sparing surgery (KSS) for upper tract urothelial cancer (UTUC) has gained increasing interest recently. However, there is limited contemporary data regarding the role of KSS in ureteral urothelial carcinoma. Therefore, we investigated the survival outcomes of ureteral urothelial carcinoma after KSS from a large prospective international UTUC registry. The Clinical Research Office of the Endourology Society-Urothelial Carcinomas of the Upper Tract (CROES-UTUC) Registry included UTUC patients who received KSS or radical nephroureterectomy (RNU) between 2014 and 2019. In this study, we included patients with ureteral UTUC only. Study outcomes included overall survival (OS), cancer-specific survival (CSS), upper tract recurrence-free survival (RFS), intravesical RFS, progression-free survival (PFS), and metastasis-free survival (MFS). Propensity score matching (PSM) was performed to balance the tumour features' differences between groups. Of 391 patients with ureteral UTUC, 309 (79.0%) received RNU, and 82 (21.0%) received KSS by ureteroscopy with laser ablation (n=28) or segmental resection (n=54). After PSM, there were no differences in OS (p=0.525), CSS (p=0.487), upper tract RFS (p=0.147), intravesical RFS (p=0.989), PFS (p=0.617), and MFS (p=0.336) between KSS and RNU. Both ureteroscopic ablation and segmental resection had similar OS, CSS, intravesical RFS, PFS, and MFS with RNU. Proximal ureteral UTUC had worse OS and CSS outcomes than other tumour locations following segmental resection. In patients with ureteral UTUC, no significant differences in long-term survival outcomes were observed between KSS and RNU. Proximal ureteral UTUC had worse survival outcomes over other tumour locations following segmental resection.

Examining the economic impacts of caregiving among families of children of medical complexity: A qualitative study to inform inclusive economic models.

Children with medical complexity (CMC) represent a heterogeneous group of children with multiple, chronic healthcare conditions. Caregivers of CMC experience a high intensity of caregiving that is often variable, extends across several networks of care, and often lasts for the entirety of the child's life. The economic impacts of caregiving are yet understudied in the CMC context. There have been recognized limitations to the sole use of quantitative methods when developing economic models of disease because they lack direct caregiver voice and context of caregiving activities and existing methods have been noted to be ableist. The purpose of this study was to explore the economic spillover impacts of caregiving among families of CMC using their own words and perspectives with the intent of expanding caregiver-centered perspectives when developing economic models. This study was a secondary analysis of a qualitative study that was conducted to examine family management practices among caregivers of CMC and their social networks. Caregivers of CMC were recruited through a Pediatric Complex Care clinic at an academic medical center in the mid-Atlantic region, USA. This study used inductive qualitative descriptive methods and the use of a template to define features of the person impacted and to define the economic construct as either a direct or indirect/spillover cost. Twenty caregivers were included in this study. Perspectives from the caregivers of CMC revealed several key themes: (1) time investment in caregiving - impacting the primary caregivers; (2) physical and mental health impacts - impacting the child themselves, siblings, and the primary caregivers; (3) impacts to leisure activities and self-care - impacting the child themselves, siblings, and the primary caregivers; (4) impacts to the social network/social capital. The themes described can be operationalized into inclusive family-centered models that represent the impacts of caregiving in the context of the family units of CMC. The use of qualitative methods to expand our development of quantitative economic models can be adapted to other populations where caregivers are involved in care. Caregivers can and should have an active voice in preference-based assessments that are operationalized in economic contexts to make them more inclusive. n/a. RR2-10.2196/14810.

Genomic sequencing research in pediatric cancer care: Decision-making, attitudes, and perceived utility among adolescents and young adults and their parents.

Professional guidelines recommend engaging adolescents and young adults (AYAs) in medical decision-making (DM), including whether to undergo genomic sequencing (GS). We explored DM around GS and attitudes after return of GS results among a diverse group of AYAs with cancer and their parents. We surveyed AYAs with cancer (n=75) and their parents (n=52) six months after receiving GS results through the Texas KidsCanSeq Study. We analyzed AYAs' DM role in GS research enrollment and their satisfaction with that role. We compared AYAs' and parents' self-reported understanding of, attitudes toward, and perceived utility of the AYAs' GS results. Most AYAs reported equally sharing DM with their parents (55%) or leading DM (36%) about GS research. Compared to their cancer care DM role, 56% of AYAs reported the same level of involvement in GS research DM while 32% were more involved and 13% were less involved (p=0.011). AYAs were satisfied (99%) with their DM role regarding GS study participation. AYAs and parents had similar self-reported understanding of, attitudes toward, and perceived utility of the GS results. Our results support engaging AYAs in DM about GS research and provide insights into AYAs' DM preferences and positive attitudes toward GS.

A strategy for successful dual-species protein expression of genes with non-optimal codon usage destined for bacterial and yeast cell factories.

Recombinant protein expression on an industrial scale traditionally utilizes one of two microbial workhorses: Escherichia coli or Saccharomyces cerevisiae. Additionally, random protein engineering of enzymes and proteins aimed for expression in S. cerevisiae are often mutagenized and pre-screened in E. coli before expression in yeast. This introduces artificial bottlenecks as the bacterial expression vector needs to be substituted for a yeast expression vector via sub-cloning, and the new library re-evaluated before a final screening in yeast. Here, we put forward a protein expression and engineering strategy that involves the use of a dual-host shuttle vector (pYB-Dual) designed with both a strong inducible yeast promoter (pGAL1), and a strong inducible bacterial promoter (pT7-RNAP), which allows for inducible protein expression in both species. Additionally, we demonstrate that by transforming the pYB-Dual vector into the E. coli strain Rosetta 2, which has elevated levels of 7 rare tRNAs, we can achieve high-level protein expression in both yeast and bacteria, even when using a mNeonGreen gene codon optimized for yeast. This dual expression vector is expected to remove bottlenecks during protein engineering of commercially important enzymes destined for high-titer expression in yeast.

The delivery and challenges of Pediatric Anesthesia within the humanitarian sector: Médecins Sans Frontières and Mercy Ships.

Access to healthcare is inequitable. Poverty, natural disasters and war disproportionally effect those most vulnerable, including children. Non-governmental organizations (NGO) hold a vital role in providing pediatric care in these contexts. Here we describe the delivery and challenges of Pediatric Anesthesia with two such non-governmental organizations; Médecins Sans Frontières (MSF) and Mercy Ships. Descriptions of both are followed by case studies.

Risk of drug-induced delirium in older patients- a pharmacovigilance study of FDA adverse event reporting system database.

Drug-induced delirium is one of the numerous known risk factors associated with increased morbidity and mortality in older patients. The objective of this study was to evaluate the risk of drug-related delirium in older patients based on the FDA Adverse Event Reporting System (FAERS). Delirium reports in older patients (age ≥65) from 2004 quarter 1 through 2021 quarter 3 extracted from the FAERS database using Open Vigil 2.1. The reported odds ratio and the proportional r7eported ratio were calculated to detect the adverse reaction signal of delirium. Combined with published evidence, suspected drugs were categorized as known, possible, or new potential delirium-risk-increasing drugs. Of the 130,885 reports (including 28,850 delirium events and 1,857 drug) analyzed for this study, 314 positive signal drugs were detected. Positive signal drugs are mainly concentrated on the drug of nervous system [n = 149, ROR 3.60, 95% CI (3.56-3.64)], cardiovascular system [n = 35, ROR 1.45, 95% CI (1.43-1.47)], alimentary tract and metabolism [n = 35, ROR 1.25, 95% CI (1.23-1.26)] and anti-infectives for systemic use [n = 27, ROR 1.70, 95% CI (1.66-1.74)]. Of the positive signal drugs, 26.11% (82/314) were known delirium-risk increasing drugs [ROR 4.12, 95%CI (3.85-4.41)], 44.90% (141/314) were possible [ROR 3.59, 95%CI (3.37-3.83)] and 28.98% (91/314) were new potential [ROR 3.68, 95%CI (3.22-4.21)]. Drug-induced delirium risk is prevalent in the older patients according to the FAERS. The risk level of drug-induced delirium should be taken into account to optimize drug therapy in clinical practice.

The Role of Pediatric Nurses During Preventable Adverse Event Disclosure: A Scoping Review.

Preventable adverse events (PAEs) occur across the healthcare spectrum and unfortunately, errors, adverse events, and PAEs are common in pediatric care. Historically, the role of disclosure of PAEs to patients and their families occurred between the dyad of physician and patient, with physicians assuming the responsibility of disclosure. In recent years, a trend toward a multidisciplinary team-based approach has emerged in some institutions, yet the role of pediatric nurses within the team disclosing a PAE is not fully understood. Given the unique relationship between pediatric nurses and their patients and their families, it is essential to understand does the literature tell us about the role of pediatric nurses during PAE disclosure? The Arksey and O'Malley scoping review method guided this study protocol and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews framework guided reporting. The final sample included five articles for synthesis: none reported or described a specific role for pediatric nurses during PAE disclosure. There is a gap in the literature on the role of pediatric nurses during PAE disclosure. Two themes emerged from this review: the use of a team-based approach to disclosure, and the need to provide emotional support to the pediatric patient and their family. There is a need for additional investigation into the role of pediatric nurses as part of a team-based disclosure process and how pediatric nurses currently provide, or desire to provide, emotional support to the patient and their family.
