ABSTRACT

BACKGROUND: Communicating well with patients is a competence central to everyday clinical practice, and communicating statistical information, especially in Bayesian reasoning tasks, can be challenging. In Bayesian reasoning tasks, information can be communicated in two different ways (which we call directions of information): The direction of Bayesian information (e.g., proportion of people tested positive among those with the disease) and the direction of diagnostic information (e.g., the proportion of people having the disease among those tested positive). The purpose of this study was to analyze the impact of both the direction of the information presented and whether a visualization (frequency net) is presented with it on patient’s ability to quantify a positive predictive value.

MATERIAL AND METHODS: 109 participants completed four different medical cases (2⨯2⨯4 design) that were presented in a video; a physician communicated frequencies using different directions of information (Bayesian information vs. diagnostic information). In half of the cases for each direction, participants were given a frequency net. After watching the video, participants stated a positive predictive value. Accuracy and speed of response were analyzed.

RESULTS: Communicating with Bayesian information led to participant performance of only 10% (without frequency net) and 37% (with frequency net) accuracy. The tasks communicated with diagnostic information but without a frequency net were correctly solved by 72% of participants, but accuracy rate decreased to 61% when participants were given a frequency net. Participants with correct responses in the Bayesian information version without visualization took longest to complete the tasks (median of 106 seconds; median of 13.5, 14.0, and 14.5 seconds in other versions).

DISCUSSION: Communicating with diagnostic information rather than Bayesian information helps patients to understand specific information better and more quickly. Patients’ understanding of the relevance of test results is strongly dependent on the way the information is presented.

ABSTRACT

BACKGROUND: To investigate the postoperative effect of dental arch changes in cleft palate patients with modified Sommerlad palatoplasty by intraoral scanning technique in early deciduous dentition children.

METHODS: Patients (n=60) with non-syndromic unilateral complete cleft lip with palate (UCLP) or cleft palate only (CPO) treated by modified Sommerlad palatoplasty without relaxed excision before 18 months old and 95 healthy controls without cleft were included. Three-dimension images of the maxillary dental arches of all subjects aged 3 to 4 years were obtained by intraoral scanning (IOS) technique. Seven parameters including anterior dental arch width (Ar-Al), middle dental arch width (Fr-Fl), posterior dental arch width (Sr-Sl), anterior palatal arch width (Cr-Cl), posterior palatal arch width (Mr-Ml), anterior dental arch length (IP-D) and entire dental arch length (IP-O) were measured.

RESULTS: Compared with male group, the Mr-Ml distance of controls in female group statistically decreased (p=0.039) and the Fr-Fl, Sr-Sl, Mr-Ml distance of female patients decreased (p=0.013, p=0.002, p=0.005). The IP-D, IP-O distance of children in UCLP group was shorter than those of CPO children (p＜0.0001, p＜0.0001). Patient group showed decreased distance of Ar-Al, Cr-Cl, IP-D and IP-O and increased distance of Sr-Sl and Mr-Ml compared with control group (p=0.0002, p=0.002, p<0.0001, p<0.0001, p=0.007, p=0.027).

CONCLUSION: The results indicated that the modified palatoplasty showed no growth inhibition in the middle, posterior dental arch width, and palatal arch width, though slightly but significantly inhibition in the length of anterior and entire dental arch.

ABSTRACT

Background: Although the beneficial effects of exclusive breastfeeding (EBF) on infants and mothers have been identified, EBF rates remain unsatisfactory. Co-parenting interventions for perinatal couples have not been systematically evaluated and analyzed for their effects on breastfeeding outcomes. Aims and Objectives: To systematically evaluate the effects of co-parenting interventions on the rate of EBF, breastfeeding knowledge, breastfeeding attitude, breastfeeding self-efficacy, parental relationship, and partner support. Methods: Randomized controlled trials and quasi-experimental studies were systematically screened in eight online databases from inception to November 2022. Trials included in this review were assessed using the Cochrane Risk of Bias Assessment Tool. Eligible trials were used to conduct a meta-analysis using Review Manager software. The I² statistic was used to assess heterogeneity between studies. When it was not possible to conduct a meta-analysis, a descriptive analysis was used to present the findings due to insufficient data from the included studies. Results: Fifteen of the 1,869 articles reviewed met the inclusion criteria. Co-parenting interventions significantly improved the EBF rate at 16 weeks (odds ratio [OR] = 3.85, 95% confidence interval, CI [1.84 to 8.03], p < 0.001, I² = 69%) and 6 months (OR = 2.82, 95% CI [1.47 to 5.41], p = 0.002, I² = 85%). This study revealed that co-parenting interventions made statistically significant improvements in parental relationship (standardized mean difference [SMD] = 0.26, 95% CI [0.13 to 0.38], p < 0.001, I² = 80%). There was no evidence of the effectiveness of interventions in terms of overall parental support (SMD = 0.75, 95% CI [-0.46 to 1.97], p < 0.001, I² = 96%). Given the discrepant and limited research data, findings on breastfeeding knowledge, breastfeeding attitudes, and breastfeeding self-efficacy were presented descriptively. Conclusion: Co-parenting interventions effectively increase EBF rates at 16 weeks and 6 months postpartum, and improve breastfeeding knowledge, breastfeeding attitude, and parental relationships.

ABSTRACT

BACKGROUND: Many options for free tissue transfer have been described for head and neck reconstruction. While functional outcomes remain paramount, aesthetic considerations like color match can be equally consequential for patient quality of life. It is important to understand differences in color match based on flap donor site for head and neck reconstruction.

METHODS: A retrospective review was performed of patients who underwent head and neck reconstruction with free tissue transfer at a tertiary care academic medical center between November 2012 and November 2020. Patients with documented pictures of their reconstruction and external skin paddles were considered. Patient demographics and surgery specific factors were recorded. Objective differences in color match were obtained by calculating the International Commission on Illumination Delta E 2000 (dE2000) score. Standard univariate descriptive statistics and multivariable statistical analyses were performed.

RESULTS: Lateral arm, parascapular, and medial sural artery perforator (MSAP) free tissue transfer performed favorably compared to other donor sites, whereas anterolateral thigh flaps had the highest average dE2000 scores. Differences in dE2000 scores were mitigated by post-operative radiation to the flap site and with increasing time beyond 6 months post-operatively.

CONCLUSIONS: We provide an objective assessment of external skin color match in patients undergoing free tissue transfer for head and neck cancer by donor site. MSAP, lateral arm, and parascapular free flaps performed well compared to traditional donor sites. These differences are more significant at the face and mandible when compared to the neck, but diminish 6 months after surgery and with post-operative radiation to the free flap skin paddle.

ABSTRACT

BACKGROUND: Despite young First Nations Australians being typically healthy, happy, and connected to family and culture, high rates of emotional distress, suicide, and self-harm are also observed. Differing worldviews of service providers and First Nations young people regarding illness and treatment practices, language differences, culturally inappropriate service models, geographical remoteness, and stigma can all inhibit access to appropriate mental health support. Mental health treatments delivered digitally (digital mental health; dMH) offer flexible access to evidence-based, nonstigmatizing, low-cost treatment and early intervention on a broad scale. There is a rapidly growing use and acceptance of these technologies among young First Nations people.

OBJECTIVE: The objective was to assess the feasibility, acceptability, and use of the newly developed Aboriginal and Islander Mental Health Initiative for Youth (AIMhi-Y) app and determine the feasibility of study procedures in preparation for future assessments of effectiveness.

METHODS: This was a nonrandomized pre-post study using mixed methods. First Nations young people aged 12-25 years who provided consent (with parental consent where appropriate) and possessed the ability to navigate a simple app with basic English literacy were included. Researchers conducted one face-to-face 20-minute session with participants to introduce and orient them to the AIMhi-Y app. The app integrates culturally adapted low-intensity cognitive behavioral therapy (CBT), psychoeducation, and mindfulness-based activities. Participants received supportive text messages weekly throughout the 4-week intervention period and completed assessments of psychological distress, depression, anxiety, substance misuse, help-seeking, service use, and parent-rated strengths and difficulties at baseline and 4 weeks. Qualitative interviews and rating scales were completed at 4 weeks to gain feedback on subjective experience, look and style, content, overall rating, check-ins, and involvement in the study. App use data were collected.

RESULTS: Thirty young people (17 males and 13 females) aged between 12 and 18 (mean 14.0, SD 1.55) years were assessed at baseline and 4 weeks. Repeated measures 2-tailed t tests showed improvements in well-being measures that were statistically and clinically significant for psychological distress (Kessler Psychological Distress Scale, 10-item) and depressive symptoms (Patient Health Questionnaire, 2-item). Participants spent on average 37 minutes in the app. The app was rated positively, with mean ratings of 4 out of 5 points (on scales of 1-5). Participants reported that they found the app easy to use, culturally relevant, and useful. The feasibility of the study was demonstrated with a 62% recruitment rate, a 90% retention rate, and high study acceptability ratings.

CONCLUSIONS: This study supports earlier research suggesting that dMH apps that are appropriately designed with and for the target populations are a feasible and acceptable means of lowering symptoms for mental health disorders among First Nations youth.

ABSTRACT

AIM: Empagliflozin (EMPA) is a sodium-glucose transporter-2 inhibitor used in the treatment of type 2 diabetes and has positive effects on cardiovascular outcomes. Amitriptyline (AMT) can be used in many clinical indications but leads to cardiotoxicity by causing QT prolongation. Our aim in this study was to determine how the effects of the concomitant use of empagliflozin and amitriptyline, which have been shown to have effects on sodium and calcium metabolism in cardiomyocytes, would cause an effect on QT and QTc intervals in clinical practice.

METHODS: Twenty-four male Wistar albino rats were randomised into four groups. The control group received only physiological serum (1 ml) via orogastric gavage (OG). The EMPA group received empagliflozin (10 mg/kg) via OG. The AMT group received amitriptyline (100 mg/kg) via OG. The AMT + EMPA group (n = 6) received amitriptyline (100 mg/kg) and empagliflozin (10 mg/kg). Under anaesthesia, QT and QTc intervals were measured at baseline, and in the first and second hours.

RESULTS: In the AMT group, QT intervals and QTc values were found to be statistically longer than in the control group (p ≤ 0.001). Empagliflozin significantly ameliorated amitriptyline-induced QT and QTc prolongation. In the AMT + EMPA group, QT and QTc intervals were significantly lower compared to that in the AMT group (p < 0.01).

CONCLUSION: In this study, we determined that empagliflozin significantly ameliorated amitriptyline-induced QT and QTc prolongation. This effect was probably due to the opposite effects of these two agents in the intracellular calcium balance. With more clinical trials, the routine use of empagliflozin may be suggested to prevent QT and QTc prolongation in diabetic patients receiving amitriptyline.

ABSTRACT

IMPORTANCE: Women with pregnancy-associated stroke might have different risks of stroke recurrence, including during subsequent pregnancies, and other cardiovascular events due to pregnancy-specific stroke risk factors, such as gestational hypertension, preeclampsia, or gestational diabetes.

OBJECTIVE: To estimate the rate of stroke recurrence, cardiovascular hospitalization, and death in women with pregnancy-associated stroke compared with women with non-pregnancy-associated stroke.

DESIGN, SETTING, AND PARTICIPANTS: This cohort study included all women aged 15 to 49 years in France who were affiliated with the general scheme of French health care insurance (94% of women) and had a first hospitalization for stroke between January 1, 2010, and December 31, 2018. Women were followed up until December 31, 2020, with the registration of stroke recurrence, hospitalization for cardiovascular conditions, and death. Data were from the French health care database Système National des Données de Santé. Statistical analyses were conducted between December 2021 and September 2022.

EXPOSURE: Pregnancy status at the time of stroke.

MAIN OUTCOMES AND MEASURES: Poisson regressions were used to estimate incidence rates of these events with 95% CIs. We used Cox proportional hazards regression models to estimate the hazard ratios (HRs) of each event during the follow-up for women with a pregnancy-associated stroke vs women with a non-pregnancy-associated stroke.

RESULTS: Among women aged between 15 and 49 years between 2010 and 2018 and living in France, 1204 had a pregnancy-associated stroke at a mean (SD) age of 31.5 (5.8) years, and 31 697 had a non-pregnancy-associated stroke at a mean age of 39.6 (8.2) years. Among the 1204 women with a pregnancy-associated stroke, the incidence rate was 11.4 (95% CI, 9.0-14.3) per 1000 person-years, with 2 recurrent events during a subsequent pregnancy. Compared with women with non-pregnancy-associated stroke, women with pregnancy-associated stroke had lower risks of ischemic stroke (adjusted HR, 0.53; 95% CI, 0.36-0.77), cardiovascular events (adjusted HR, 0.58; 95% CI, 0.49-0.69), and death (adjusted HR, 0.42; 95% CI, 0.22-0.79). In contrast, the risk of recurrent intracerebral hemorrhage and cerebral venous thrombosis did not differ significantly, whereas the risks of venous thromboembolism (HR, 2.02; 95% CI, 1.14-3.58) and acute coronary syndrome with ST-segment elevation (HR, 3.93; 95% CI, 1.10-14.0) were increased.

CONCLUSIONS AND RELEVANCE: In this cohort study, although the risks of ischemic stroke, overall cardiovascular events, and mortality were lower after a pregnancy-associated stroke than after a non-pregnancy-associated stroke, the risks of venous thromboembolism and acute coronary syndrome with ST-segment elevation were higher. Recurrent stroke during a subsequent pregnancy remained rare.

ABSTRACT

IMPORTANCE: Suicidal behavior is a significant clinical concern in individuals with borderline personality disorder (BPD), but the effectiveness of pharmacotherapy on reducing suicide risk has remained unknown.

OBJECTIVE: To study the comparative effectiveness of different pharmacotherapies in preventing attempted or completed suicides in patients with BPD in Sweden.

DESIGN, SETTING AND PARTICIPANTS: In this comparative effectiveness research study, nationwide Swedish register databases of inpatient care, specialized outpatient care, sickness absences, and disability pensions were used to identify patients aged 16 to 65 years with registered treatment contact due to BPD during 2006 to 2021. Data were analyzed from September to December 2022. A within-individual design was used, in which each patient was used as their own control to eliminate selection bias. To control protopathic bias, sensitivity analyses were conducted, in which the first 1 or 2 months of medication exposure were omitted from the analyses.

MAIN OUTCOMES AND MEASURES: Hazard ratio (HR) for attempted or completed suicide.

RESULTS: A total of 22 601 patients with BPD (3540 [15.7%] men; mean [SD] age, 29.2 [9.9] years) were included. During the 16-year follow-up (mean [SD] follow-up, 6.9 [5.1] years), 8513 hospitalizations due to attempted suicide and 316 completed suicides were observed. Attention-deficit/hyperactive disorder (ADHD) medication treatment, compared with its nonuse, was associated with a decrease in the risk of attempted or completed suicide (HR, 0.83; 95% CI, 0.73-0.95; false discovery rate [FDR]-corrected P = .001). Treatment with mood stabilizers did not have a statistically significant association with the main outcome (HR, 0.97; 95% CI, 0.87-1.08; FDR-corrected P = .99). Antidepressant (HR, 1.38; 95% CI, 1.25-1.53; FDR-corrected P < .001) and antipsychotic (HR, 1.18; 95% CI, 1.07-1.30; FDR-corrected P < .001) treatments were associated with an elevated risk of attempted or completed suicide. Of the investigated pharmacotherapies, treatment with benzodiazepines was associated with the highest risk of attempted or completed suicide (HR, 1.61; 95% CI, 1.45-1.78; FDR-corrected P < .001). These results remained similar when controlling for potential protopathic bias.

CONCLUSIONS AND RELEVANCE: In this comparative effectiveness research study of a Swedish nationwide cohort, ADHD medication was the only pharmacological treatment associated with reduced risk of suicidal behavior among patients with BPD. Conversely, the findings suggest that benzodiazepines should be used with care among patients with BPD due to their association with increased risk of suicide.

ABSTRACT

IMPORTANCE: Lymphedema is a debilitating condition that affects approximately 1 in 1000 individuals in the United States. Complete decongestive therapy is currently the standard of care, and innovative surgical techniques have demonstrated potential to further improve outcomes. Despite the growing armamentarium of treatment options, a large proportion of patients with lymphedema continue to struggle because of limited access to care.

OBJECTIVE: To define the current state of insurance coverage for lymphedema treatments in the United States.

DESIGN, SETTING, AND PARTICIPANTS: A cross-sectional analysis of insurance reimbursement for lymphedema treatments in 2022 was designed. The top 3 insurance companies per state based on market share and enrollment data maintained by the Kaiser Family Foundation were included. Established medical policies were gathered from insurance company websites and phone interviews, and descriptive statistics were performed.

MAIN OUTCOMES AND MEASURES: Treatments of interest included nonprogrammable pneumatic compression, programmable pneumatic compression, surgical debulking, and physiologic procedures. Primary outcomes included level of coverage and criteria for coverage.

RESULTS: This study included 67 health insurance companies representing 88.7% of the US market share. Most insurance companies offered coverage for nonprogrammable (n = 55, 82.1%) and programmable (n = 53, 79.1%) pneumatic compression. However, few insurance companies offered coverage for debulking (n = 13, 19.4%) or physiologic (n = 5, 7.5%) procedures. Geographically, the lowest rates of coverage were seen in the West, Southwest, and Southeast.

CONCLUSIONS AND RELEVANCE: This study suggests that in the United States, less than 12% of individuals with health insurance, and even fewer patients without health insurance, have access to pneumatic compression and surgical treatments for lymphedema. The stark inadequacy of insurance coverage must be addressed through research and lobbying efforts to mitigate health disparities and promote health equity among patients with lymphedema.

ABSTRACT

IMPORTANCE: Modeling genetic nurture (ie, the effects of parental genotypes through influences on the environment experienced by their children) is essential to accurately disentangle genetic and environmental influences on phenotypic variance. However, these influences are often ignored in both epidemiologic and genetic studies of depression.

OBJECTIVE: To estimate the association of genetic nurture with depression and neuroticism.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study jointly modeled parental and offspring polygenic scores (PGSs) across 9 traits to test for the association of genetic nurture with lifetime broad depression and neuroticism using data from nuclear families in the UK Biobank, with data collected between 2006 and 2019. A broad depression phenotype was measured in 38 702 offspring from 20 905 independent nuclear families, with most of these participants also reporting neuroticism scores. Parental genotypes were imputed from sibships or parent-offspring duos and used to calculate parental PGSs. Data were analyzed between March 2021 and January 2023.

MAIN OUTCOMES AND MEASURES: Estimates of genetic nurture and direct genetic regression coefficients on broad depression and neuroticism.

RESULTS: This study of 38 702 offspring with data on broad depression (mean [SD] age, 55.5 [8.2] years at study entry; 58% female) found limited preliminary evidence for a statistically significant association of genetic nurture with lifetime depression and neuroticism in adults. The estimated regression coefficient of the parental depression PGS on offspring neuroticism (β = 0.04, SE = 0.02, P = 6.63 × 10-3) was estimated to be approximately two-thirds (66%) that of the offspring’s depression PGS (β = 0.06, SE = 0.01, P = 6.13 × 10-11). Evidence for an association between parental cannabis use disorder PGS and offspring depression was also found (β = 0.08, SE = 0.03, P = .02), which was estimated to be 2 times greater than the association between the offspring’s cannabis use disorder PGS and their own depression status (β = 0.04, SE = 0.02, P = .07).

CONCLUSIONS AND RELEVANCE: The results of this cross-sectional study highlight the potential for genetic nurture to bias results from epidemiologic and genetic studies on depression or neuroticism and, with further replication and larger samples, identify potential avenues for future prevention and intervention efforts.
