ABSTRACT

INTRODUCTION: Outcomes of deceased donor kidney transplant (DDKT) recipients from the same donor with donor-recipient sex discordance have been studied with inconsistent results.

METHODS: Adult DDKT where both kidneys from the same donor occurred at our center in two different recipients of different sexes were included. Outcomes were analyzed separately for male and female donors, based on the concordance or discordance between donor-recipient sex: Male-male (M-m) versus Male to female (M-f) or vice versa, F-f versus F-m. Acute rejection (AR) and uncensored graft failure were primary outcomes of interest. The univariate and multivariate risks for AR and graft failure were conducted using the Cox proportional hazards model and log-rank tests.

RESULTS: A total of 130 donors, 84 male and 46 female fulfilled our selection criteria and were transplanted in 260 recipients. With respect to the concordant groups (M-m or F-f), sex discordance was not significantly associated with the risk of rejection in multivariate analysis (M-f vs. M-m HR 1.15 [0.53-2.53, P = 0.72]; F-m vs. F-f HR 1.77 [0.71-4.39, P = 0.23]). Sex discordance was also not significantly associated with graft failure in multivariate analysis. Interestingly, risk factors for AR differed among male donors and female donors. The higher calculated panel reactive antibodies (cPRA) and nonwhite recipients were at increased risk for AR in F-m, but not in M-f.

CONCLUSIONS: Donor-recipient sex discordance was not significantly associated with AR or graft failure. Risk factors for AR may differ across male and female donors.

ABSTRACT

INTRODUCTION: There is a lack of data regarding SARS-CoV-2 vaccination rates and tixagevimab-cilgavimab (TC) uptake among pediatric solid organ transplant recipients. The purpose of our study was to assess these rates.

MATERIALS AND METHODS: We reviewed vaccination records of pediatric recipients of heart, kidney, and liver transplants at Mayo Clinic, Rochester, MN, who received a transplant between January 2011 and December 2021. All SARS-CoV-2 vaccines and doses of TC received on or before September 1, 2022, the date of approval of the bivalent SARS-CoV2 vaccine, were included. We also assessed whether patients had been seen by an infectious diseases physician (ID) in the preceding 6 months.

RESULTS: Our study included 110 patients: 47 kidney, 36 heart, and 27 liver transplant recipients. All vaccine doses recorded were monovalent SARS-CoV-2 vaccines. Sixty-eight (61.8%) patients received at least one vaccine. This varied by age group, with f of ≥12 years olds, 40.9% of 5-11 year olds and 14.3% of under 5 year olds (p = 0.001). Seven patients (6.4%) were up-to-date (UTD) for age. There was no difference in UTD status by organ type (p = 0.335). Patients who saw ID were significantly more likely to be UTD (13.2% versus 2.8%; p = 0.047). Among those eligible, 14 (18.2%) received TC, with rates not different based on transplanted organ type (p = 0.158) or whether they saw ID (p = 0.273).

CONCLUSIONS: Despite the availability of vaccines, nearly 40% of pediatric solid organ transplant recipients remained unvaccinated against SARS-CoV-2 at time of the bivalent vaccine release. Less than a fifth of eligible patients received TC. Strategies to increase uptake of SARS-CoV-2 vaccines as well as adjunctive agents among this vulnerable group should be further explored.

ABSTRACT

PROBLEM: The vaginal microbiome has a substantial role in the occurrence of preterm birth (PTB), which contributes substantially to neonatal mortality worldwide. However, current bioinformatics approaches mostly concentrate on the taxonomic classification and functional profiling of the microbiome, limiting their abilities to elucidate the complex factors that contribute to PTB.

METHOD OF STUDY: A total of 3757 vaginal microbiome 16S rRNA samples were obtained from five publicly available datasets. The samples were divided into two categories based on pregnancy outcome: preterm birth (PTB) (N = 966) and term birth (N = 2791). Additionally, the samples were further categorized based on the participants’ race and trimester. The 16S rRNA reads were subjected to taxonomic classification and functional profiling using the Parallel-META 3 software in Ubuntu environment. The obtained abundances were analyzed using an integrated systems biology and machine learning approach to determine the key microbes, pathways, and genes that contribute to PTB. The resulting features were further subjected to statistical analysis to identify the top nine features with the greatest effect sizes.

RESULTS: We identified nine significant features, namely Shuttleworthia, Megasphaera, Sneathia, proximal tubule bicarbonate reclamation pathway, systemic lupus erythematosus pathway, transcription machinery pathway, lepA gene, pepX gene, and rpoD gene. Their abundance variations were observed through the trimesters.

CONCLUSIONS: Vaginal infections caused by Shuttleworthia, Megasphaera, and Sneathia and altered small metabolite biosynthesis pathways such as lipopolysaccharide folate and retinal may increase the susceptibility to PTB. The identified organisms, genes, pathways, and their networks may be specifically targeted for the treatment of bacterial infections that increase PTB risk.

ABSTRACT

STUDY DESIGN: Prospective Cohort Study.

OBJECTIVE: The present study aims to determine if the racial representation of patients enrolled in a large prospective scoliosis registry is reflective of the general United States population. Further, we studied whether there was an association between race, pre-operative parameters, outcomes and loss to follow-up.

METHODS: Prospectively collected data for patients who underwent spinal fusion for adolescent idiopathic scoliosis (AIS) was reviewed, including self-reported race/ethnicity. The U.S. pediatric population and U.S. patients enrolled in the prospective registry were compared. The data obtained was analyzed for variations between races, for pre-operative variables and follow-up.

RESULTS: Of the 2210 included patients in the registry 66% of patients reported as White, while 52% of the 2018 U.S. pediatric population reported as White. 15% of the registry reported as Hispanic/Latino compared to 22% of the U.S. pediatric population, 13% Black compared to 14% of the U.S. pediatric population, and 4% Asian compared to 5% of the U.S. pediatric population. Asian and White patients had statistically significant higher 2-year follow-up in all but one of six enrollment sites (P < 0.001). Native American, Other, and Hispanic/Latino patients had the highest BMIs. Native American and Black patients had the highest pre-op thoracic Cobb angles. Pre-op ages of Black, Hispanic, and Native American patients were statistically lower (P < 0.01).

CONCLUSION: This study demonstrates the association between race and patient follow-up and pre-operative factors in patients who underwent surgery for AIS. Black, Native American, and Hispanic populations were underrepresented both at pre-op and follow-up when compared to their relative proportion in the U.S. pediatric population.

ABSTRACT

During the COVID-19 pandemic, pancreatic surgery for pancreatic neuroendocrine tumors (PNETs) with surgical indications was postponed or canceled. Patients with PNET patients who underwent pancreatic surgery during the COVID-19 restriction period (3 years) were compared with a similar cohort of patients who underwent surgery in the previous 3 years. Data on patients’ characteristics, waiting time, and surgical and pathology outcomes were evaluated. During the study period, 370 patients received surgery for PNETs, 205 (55%) during the first period, and 165 (45%) during the pandemic. A lengthening of the waiting list (182 [IQR 100-357] vs. 60 [40-88] days, p < 0.001) and increased use of anti-tumor medical treatments (any therapy, peptide receptor radionuclide therapy, and somatostatin analogs; all p < 0.001) was found. During the pandemic, surgery occurred after a median of 381 days [IQR 200-610] from diagnosis (vs. 103 [IQR 52-192] of the pre-COVID-19 period, p < 0.001). No statistically significant differences in tumor size and grading distribution were found between the two periods (both p > 0.05), yet only a modest increase of the median Ki67 values in cases operated during the pandemic (4% vs. 3%, p = 0.03). Lastly, these latter patients experienced less major postoperative complications (13% vs. 24%, p = 0.007). During COVID-19, the surgical waiting list of PNET patients was drastically extended, and bridge therapies were preferred. This did not result in more advanced cases at final pathology. PRRT and SSA are valid alternative therapies for PNETs when surgery is not feasible.

ABSTRACT

Parastomal hernias (PSH) are difficult to manage and associated with high rates of postoperative recurrence and complications. Sugarbaker and three-dimensional (3-D) mesh repair are commonly used methods for the surgical treatment of PSH. However, the efficacy and safety of these surgical techniques have not been adequately compared. Patients with PSH who received 3-D mesh or Sugarbaker repair at our center from August 2012 to May 2023 were included. We retrospectively analyzed their demographic data and postoperative outcomes. The primary outcome measure was the recurrence rate at 1-year follow-up. A total of 86 patients were enrolled, involving 53 in the 3-D mesh (62%) group and 33 in the Sugarbaker (38%) group. Most cases (73%) involved were the laparoscopic approach. The recurrence rate at 1-year follow-up was 15% (eight cases) in the 3-D mesh group and 24% (eight cases) in the Sugarbaker group, with no statistical significance (P = 0.29). Additionally, no differences were observed between the 3-D mesh and Sugarbaker groups in the length of hospitalization or in short- and long-term complications. Sugarbaker and 3-D mesh repair have similar clinical efficacy in the surgical treatment of PSH. Further randomized controlled trials are required to confirm these results.Trial registration number.This study was retrospectively registered at clinicaltrials.gov (NCT06077318).

ABSTRACT

The present article aims to describe the different steps on how to design, develop and conduct quantitative and qualitative Spirituality and Health (S/H) studies from a Brazilian perspective, discussing definitions and instruments, and proposing a “how-to guide” for those interested in this field of research. A narrative review of the literature has been conducted by experts in the field of S/H aiming to develop a “how-to-guide”. Spirituality is a very complex concept that has several challenges in the current scientific literature, including the lack of consensus in the definitions, the numerous dimensions assessed, the diverse instruments for measurement, the criticisms from other scholars, the great diversity of religious and cultural traditions and the growing number of “spiritual but not religious” individuals. This review supports that S/H studies may follow the high scientific standards, using consolidated research procedures and solid methods for both qualitative and quantitative research. Some peculiarities of the research methods for this field are discussed. S/H research is still under development, and there are several future directions for S/H studies, aiming to minimize previous criticisms and generating stronger evidence.

ABSTRACT

INTRODUCTION: Dyspnea associated with acute respiratory tract infections is a common cause of emergency admissions and can be distressing for children. This study aimed to evaluate the impact of a handheld fan intervention on physiological parameters in pediatric patients with dyspnea.

METHODS: A total of 59 children aged 2 to 12 years presenting to an emergency department for upper respiratory tract infection between March 2022 and March 2023 were assigned to the experimental group (n = 32) or control group (n = 27) by urn randomization. Both groups received the hospital’s standard care, including 3 doses of inhaled bronchodilator at 20-minute intervals. The fan intervention consisted of parents applying a handheld electric fan to the child’s face at a distance of 15 cm for 5 minutes after each inhaler treatment. Oxygen saturation, heart rate, and respiratory rate were recorded before treatment and after the 3 inhaler treatments.

RESULTS: There were no statistical differences in descriptive characteristics between the experimental and control groups (P > .05). Oxygen saturation values were significantly higher in the control group before treatment but showed greater increases in the intervention group after treatment (P < .001). The intervention group also exhibited greater reductions than the control group in both heart rate and respiratory rate after the third treatment than pretreatment values (P < .05).

DISCUSSION: The handheld fan intervention effectively supports inhaler treatment for children with dyspnea. Further studies are recommended to assess its impact across different age groups and clinical conditions.

ABSTRACT

OBJECTIVE: To highlight the possible surgical steps that could affect the neural supply of soft palate and velopharyngeal sphincter during Furlow palatoplasty and posteriorly-based myo-mucosal buccal flaps in patients with persistent velopharyngeal insufficiency after primary cleft palate repair.

DESIGN: Institution-based retrospective study.

SETTING: Academic Medical Center.

PATIENTS: Non-syndromic patients with persistent hypernasality (after primary cleft palate repair) who had Furlow palatoplasty or posteriorly-based buccal myo-mucosal flaps and were followed up for at least 60 months after the secondary surgery.

INTERVENTIONS: All patients were examined using a fiberoptic endoscopy, the movement of components of the velopharyngeal sphincter: soft palate, and lateral pharyngeal walls were traced on the monitor and given a score from 0-4. The pattern of VPS closure was reported whether coronal, circular, or sagittal for each case.

MAIN OUTCOME MEASURES: Patients’ characteristics, auditory perceptual assessment, the severity of hypernasality, intraoperative lengthening of the palate, and operative complications were recorded.

RESULTS: At postoperative (at least 60 months) evaluation of the patients statistically non-significant differences were reported when comparing the pre-versus post-operative auditory perceptual assessment following both procedures (P value ≥0.05). A greater tendency towards improvement was noticed with BF but was non-significant.

CONCLUSION: The nerve supply of the palate could be jeopardized by many techniques of primary or secondary repair of the cleft palate leaving behind a deceiving intact but weak poor-functioning palate. All efforts should be made to provide more neural-preservation techniques in primary/secondary repair of the cleft palate. Further wide-scale research is essential to have final clear conclusions.

ABSTRACT

BACKGROUND: Generalized anxiety disorder (GAD) is a prevalent anxiety disorder characterized by uncontrollable worry, trouble sleeping, muscle tension, and irritability. Cognitive behavioural therapy (CBT) is one of the first-line treatments that has demonstrated high efficacy in reducing symptoms of anxiety. Electronically delivered CBT (e-CBT) has been a promising adaptation of in-person treatment, showing comparable efficacy with increased accessibility and scalability. Finding further scalable interventions that can offer benefits to patients requiring less intensive interventions can allow for better resource allocation. Some studies have indicated that weekly check-ins can also lead to improvements in GAD symptoms. However, there is a lack of research exploring the potential benefits of online check-ins for patients with GAD.

OBJECTIVE: This study aims to investigate the effects of weekly online asynchronous check-ins on patients diagnosed with GAD and compare it with a group receiving e-CBT.

METHODS: Participants (n e-CBT = 45; n check-in = 51) with GAD were randomized into either an e-CBT or a mental health check-in program for 12 weeks. Participants in the e-CBT program completed pre-designed modules and homework assignments through a secure online delivery platform where they received personalized feedback from a trained care provider. Participants in the mental health check-in condition had weekly asynchronous messaging communication with a care provider where they were asked structured questions with a different weekly theme to encourage conversation.

RESULTS: Both treatments demonstrated statistically significant reductions in GAD-7-item questionnaire (GAD-7) scores over time, but when comparing the groups there was no significant difference between the treatments. The number of participants who dropped out and baseline scores on all questionnaires were comparable for both groups.

CONCLUSIONS: The findings support the effectiveness of e-CBT and mental health check-ins for the treatment of GAD.
