This study investigates the seasonal and regional distribution of paediatric laryngomalacia admissions in the United States, hypothesizing higher admission rates in winter and colder regions due to reduced sunlight exposure affecting vitamin D levels.

We analyzed data from the 2016 Kids’ Inpatient Database (KID), focusing on children under three years old. Laryngomalacia cases were identified using International Classification of Diseases and Related Health Problems 10th Revision (ICD-10) code Q31.5. Seasonal and regional differences in admission rates were assessed using Pearson’s chi-squared test, with a significance level of p less than 0.05.

Of 4,512,196 estimated national admissions, 11,638 were due to laryngomalacia. Admissions increased by 10.0 per cent in winter and decreased by 10.9 per cent in summer (p < 0.005). Regionally, admissions were higher in the Midwest/Central (18.6 per cent) and Northeast (9.3 per cent) and lower in the South (7.4 per cent) and West (11.1 per cent) (p < 0.005).

Laryngomalacia admissions are significantly influenced by seasonal and regional factors, likely related to environmental conditions affecting vitamin D synthesis.

In response to the COVID-19 pandemic, we rapidly implemented a plasma coordination center, within two months, to support transfusion for two outpatient randomized controlled trials. The center design was based on an investigational drug services model and a Food and Drug Administration-compliant database to manage blood product inventory and trial safety.

A core investigational team adapted a cloud-based platform to randomize patient assignments and track inventory distribution of control plasma and high-titer COVID-19 convalescent plasma of different blood groups from 29 donor collection centers directly to blood banks serving 26 transfusion sites.

We performed 1,351 transfusions in 16 months. The transparency of the digital inventory at each site was critical to facilitate qualification, randomization, and overnight shipments of blood group-compatible plasma for transfusions into trial participants. While inventory challenges were heightened with COVID-19 convalescent plasma, the cloud-based system, and the flexible approach of the plasma coordination center staff across the blood bank network enabled decentralized procurement and distribution of investigational products to maintain inventory thresholds and overcome local supply chain restraints at the sites.

The rapid creation of a plasma coordination center for outpatient transfusions is infrequent in the academic setting. Distributing more than 3,100 plasma units to blood banks charged with managing investigational inventory across the U.S. in a decentralized manner posed operational and regulatory challenges while providing opportunities for the plasma coordination center to contribute to research of global importance. This program can serve as a template in subsequent public health emergencies.

Behaviour Change Communication (BCC) intervention programmes often lack documentation of successful processes. This manuscript aims to describe the development of Program Impact Pathway (PIP) using Theory of Change (ToC) approach for a mHealth BCC intervention titled ‘Mobile Solutions Aiding Knowledge for Health Improvement (M-SAKHI)’ aimed at reducing stunting in infants at 18 months of age.

The PIP was developed using ToC to design the intervention and plan its implementation. Literature review and data from previous pilots helped to identify health service gaps that needed to be addressed by the PIP of this intervention.

M-SAKHI was implemented in 244 villages under governance of forty primary health centres of Nagpur and Bhandara districts of eastern Maharashtra in central India.

The study investigators and the public health stakeholders participated in developing the PIP. M-SAKHI evaluation study recruited 2501 pregnant women who were followed up through delivery until their infants were 18 months old.

The PIP was developed, and it identified the following pathways for the final impact: (1) improving maternal and infant nutrition, (2) early recognition of maternal and infant danger signs, (3) improving access and utilisation to healthcare services, (4) improving hygiene, sanitation and immunisation practices, and (5) improving implementation and service delivery of community health workers through their training, monitoring and supervision in real time.

This paper will illustrate the significance of development of PIP for M-SAKHI. It can aid other community-based programmes to design their PIP for nutrition-based BCC interventions.

Chronic pain patients often contend with insomnia symptoms, creating a reciprocal relationship that adds complexity to their condition. Evaluating interventions targeting insomnia in this population becomes paramount, given the intertwined nature of pain and sleep disturbances.

This retrospective pretest design aimed to assess the efficacy of an Internet-delivered sound healing intervention in reducing insomnia severity and addressing sleep- and pain-related parameters among individuals with chronic pain.

Conducted as a community-based project, Tuning for Health provided support to individuals grappling with long-term illnesses. The intervention involved the virtual delivery of a specially crafted sound track using tuning forks over a 6-week period, supervised by an experienced therapist and administered weekly for an hour. Participants were instructed to play the track daily at a time convenient for them. A total of 68 participants (mean age 59.3 years) completed the intervention. Outcome measures, including the Insomnia Severity Index (ISI), a sleep diary, and assessments for anxiety, depression, and pain-related parameters, were collected at the end of the 6-week intervention and repeated after a 6-month follow-up. Negative effects were monitored and reported.

Significant immediate interaction effects (time by treatment) were observed for the pain severity, ISI and various sleep parameters, such as sleep efficiency, sleep onset latency, early morning awakenings, and wake time after sleep onset. A time effect for anxiety and depression was noted at the 6-month follow-up. The group exhibited highly significant improvements in pain-related parameters. At the 6-month follow-up, sustained enhancements in sleep parameters and mental health were reported, with no reported side effects.

These unique results suggest the potential efficacy of sound healing in alleviating chronic pain and associated insomnia. Further research with a larger sample size is warranted to validate these findings. Combining sound healing with other treatments may offer enhanced outcomes for individuals dealing with both chronic pain and comorbid insomnia. This study lays the groundwork for future investigations into the promising intersection of sound healing, chronic pain management, and sleep improvement.

PTEN hamartoma tumour syndrome (PHTS) comprises a group of genetic disorders with varied clinical presentations, including macrocephaly, developmental delay, and increased cancer susceptibility. Recent reports have highlighted the occurrence of tonsil-related issues in PHTS.

Clinical data focusing on tonsil-related pathology and tonsillectomy details (indications, histology and post-operative complications) were collected from 53 patients with PHTS.

Tonsil issues affected 58 per cent of the cohort, with 43 per cent requiring tonsillectomy. Primary indications for tonsillectomy included obstructive sleep apnoea (43 per cent), recurrent tonsillitis (17 per cent) and other causes (17 per cent). Tonsil-related problems were observed both before (45 per cent) and after (55 per cent) PHTS. Tonsillectomy with adenoidectomy was the predominant surgical intervention performed (87 per cent), spanning a broad age range (1–27 years old).

Our findings highlight the complex nature of PHTS and its association with tonsil-related pathology, demonstrating its relevance for ENT surgeons. Early recognition and intervention are pivotal for managing sleep apnoea and the associated health problems.

To compare how clinical researchers generate data-driven hypotheses with a visual interactive analytic tool (VIADS, a visual interactive analysis tool for filtering and summarizing large datasets coded with hierarchical terminologies) or other tools.

We recruited clinical researchers and separated them into “experienced” and “inexperienced” groups. Participants were randomly assigned to a VIADS or control group within the groups. Each participant conducted a remote 2-hour study session for hypothesis generation with the same study facilitator on the same datasets by following a think-aloud protocol. Screen activities and audio were recorded, transcribed, coded, and analyzed. Hypotheses were evaluated by seven experts on their validity, significance, and feasibility. We conducted multilevel random effect modeling for statistical tests.

Eighteen participants generated 227 hypotheses, of which 147 (65%) were valid. The VIADS and control groups generated a similar number of hypotheses. The VIADS group took a significantly shorter time to generate one hypothesis (e.g., among inexperienced clinical researchers, 258 s versus 379 s, p = 0.046, power = 0.437, ICC = 0.15). The VIADS group received significantly lower ratings than the control group on feasibility and the combination rating of validity, significance, and feasibility.

The role of VIADS in hypothesis generation seems inconclusive. The VIADS group took a significantly shorter time to generate each hypothesis. However, the combined validity, significance, and feasibility ratings of their hypotheses were significantly lower. Further characterization of hypotheses, including specifics on how they might be improved, could guide future tool development.

Depression is common in persons with MS (PwMS), substantially contributing to morbidity and mortality. Depression can dually impact PwMS as both a psychosocial reaction to living with the disease and a neurological effect of it. Cardinal features of depression include reduced ability to seek and experience pleasure, often attributed to dysregulation of the brain's reward system. People with depression exhibit atypical reward processing, as do fatigued PwMS. However, it is unclear whether MS itself affects reward processing, and whether it interacts with depression. The current study explored the associations of depression, MS, and their interaction on reward responsiveness. We hypothesized that depression and MS would independently be associated with poorer reward responsiveness and that they would interact synergistically to impair reward responsiveness.

Forty PwMS and 40 healthy age- and education-matched healthy controls (HC) participated in a computerized switching task with high- and low-reward manipulations. The Chicago Multiscale Depression Inventory (CMDI) Mood subscale measured depressive symptoms. The Behavioral Inhibition/Activation Scales (BIS/BAS) measured self-reported reward responsiveness and behavioral inhibition. Switching task performance was measured as response time (RT) and accuracy. Performance differences between the high- and low-reward conditions represented performance-based reward responsiveness. Linear mixed effects models were used to estimate the associations of MS and depression with reward responsiveness, behavioral inhibition, and task performance.

Depression, but not MS, was associated with higher BIS scores (p=.007). Neither depression nor MS was associated with BAS subscales. On the switching task, participants who reported lower depression responded to reward such that they were slightly faster in the high-reward condition compared to the low-reward condition (p=.07). By contrast, in participants who reported higher depression, there was no effect of reward on response time. Additionally, MS (p=.009) and depression (p=.018) were each associated with slower response times. Regarding accuracy, no effects of reward were observed; however, there was an interaction between MS and depression. Among HC participants, depression was not related to accuracy. In comparison, PwMS who reported higher depression were more accurate than PwMS who reported less depression (p=.043).

Consistent with hypotheses, higher depressive symptoms were associated with increased behavioral inhibition. Depression was not associated with self-reported reward responsiveness, but it was associated with reduced reward responsiveness on a cognitive task. Contrary to hypotheses, MS was not associated with reduced reward responsiveness. Additionally, higher depression and an MS diagnosis were related to slower response time, consistent with prior findings that psychomotor slowing is a hallmark feature of both disorders. Interestingly, we observed a unique behavioral trend in PwMS, such that PwMS with higher depressive symptoms were more accurate than PwMS with lower depressive symptoms, whereas this relationship was not present among HCs. Altogether, depression in both PwMS and cognitively healthy individuals may be associated with blunted reward responsiveness, but MS does not exacerbate this relationship. In fact, PwMS with depression may be more conscientious in their functioning and therefore perform better on cognitive task accuracy. Continued work should examine how reward processing and its underlying mechanisms may differ in depressed PwMS.

Investigate and mitigate a cluster of Candida auris cases among incarcerated patients in a maximum-security prison hospital utilizing contact tracing, screening, whole genome sequencing, and environmental sampling and decontamination.

Outbreak investigation.

Inpatient prison hospital affiliated with an academic tertiary referral center.

Inmates of the Texas Department of Criminal Justice.

Epidemiologic and environmental investigations were conducted including contact tracing, point prevalence surveys, and environmental sampling. Whole genome sequencing was performed on positive patient isolates.

Following a clinical case of C. auris fungemia, 344 patients underwent C. auris surveillance screening. Eight (2.3%) patients were identified with C. auris colonization. All patients were male. Our index patient was the only clinical case and death. Whole genome sequencing was performed on the nine patient isolates. All isolates were clade III (Africa) and clustered together with the largest SNP difference being 21. Environmental cultures from 7 of 61 rooms (11.5%) were positive following terminal disinfection with bleach. Sites nearest to the patient were most often positive including the hospital bed rails and bedside table. The transmission cluster was successfully mitigated within 60 days of identification.

Implementation of an aggressive surveillance and decontamination program resulted in mitigation of a C. auris transmission cluster among our incarcerated patients. This investigation provides valuable insight into C. auris transmission in the incarcerated population, which is not considered a classic high-risk population as well as the challenges faced to stop transmission in a facility that requires the use of shared patient environments.

We sought to evaluate the impact of antibiotic selection and duration of therapy on treatment failure in older adults with catheter-associated urinary tract infection (CA-UTI).

We conducted a population-based cohort study comparing antibiotic treatment options and duration of therapy for non-hospitalized adults aged 66 and older with presumed CA-UTI (defined as an antibiotic prescription and an organism identified in urine culture in a patient with urinary catheterization documented within the prior 90 d). The primary outcome was treatment failure, a composite of repeat urinary antibiotic prescribing, positive blood culture with the same organism, all-cause hospitalization or mortality, within 60 days. We determined the risk of treatment failure accounting for age, sex, comorbidities, and healthcare exposure using log-binomial regression.

Of 4,436 CA-UTI patients, 2,709 (61.1%) experienced treatment failure. Compared to a reference of TMP-SMX (61.9% failure), of those treated with fluoroquinolones, 56.3% experienced failure (RR 0.91, 95% CI: 0.85–0.98) and 60.9% of patients treated with nitrofurantoin experienced failure (RR 1.02, 95% CI: 0.94–1.10). Compared to 5–7 days of therapy (treatment failure: 59.4%), 1–4 days was associated with 69.5% failure (RR 1.15, 95% CI: 1.05–1.27), and 8–14 days was associated with a 62.0% failure (RR 1.05, 95% CI: 0.99–1.11).

Although most treatment options for CA-UTI have a similar risk of treatment failure, fluoroquinolones, and treatment durations ≥ 5 days in duration appear to be associated with modestly improved clinical outcomes. From a duration of therapy perspective, this study provides reassurance that relatively short courses of 5–7 days may be reasonable for CA-UTI.

Preventing psychiatric admissions holds benefits for patients as well as healthcare systems. The Clinical Global Impression-Severity (CGI-S) scale is a 7-point measurement of symptom severity, independent of diagnosis, which has shown capability of predicting risk of hospitalisation in schizophrenia. Due to its routine use in clinical practice and ease of administration, it may have potential as a transdiagnostic predictor of hospitalisation.

To investigate whether early trajectories of CGI-S scores predict risk of hospitalisation over a 6 month-follow-up period.

A retrospective cohort study was conducted, analysing Electronic Health Record (EHR) data from the NeuroBlu Database (Patel et al. BMJ Open 2022;12:e057227). Patients were included if they had a psychiatric diagnosis and at least 5 recorded CGI-S scores within a 2-month period, defined as the ‘index’ period. The relationship between early CGI-S trajectories and risk of hospitalisation was investigated using Cox regression. The analysis was adjusted for age, gender, race, number of years in education, and psychiatric diagnosis. Early CGI-S trajectories were estimated as clinical severity (defined as the mean CGI-S score during the index period) and clinical instability (defined as a generalised Root Mean Squared Subsequent Differences of all CGI-S scores recorded during the index period). The primary outcome was time to psychiatric hospitalisation up to 6 months following the index period. Patients who had been hospitalised before or within the index period were excluded.

A total of 36,914 patients were included (mean [SD] age: 29.7 [17.5] years; 57.3% female). Clinical instability (hazard ratio: 1.09, 95% CI 1.07-1.10, p<0.001) and severity (hazard ratio: 1.11, 95% CI 1.09-1.12, p<0.001) independently predicted risk of hospitalisation. These associations were consistent across all psychiatric diagnoses. Patients in the top 50% of severity and/or instability were at a 45% increased risk of hospitalisation compared to those in the bottom 50% (Figure 1).

Image:

Early CGI-S trajectories reflecting clinical severity and instability independently predict risk of hospitalisation across diagnoses. This risk was compounded when instability and severity were present together. These results have translation potential in predicting individuals who are at high risk of hospitalisation and could benefit from preventative strategies to mitigate this risk.
