Patient Navigation by Community Health Workers Increases Access to Surgical Care in Rural Haiti

Introduction

In the Hôpital Albert Schweitzer district in rural Haiti, patients from mountain areas receive fewer operations per capita than patients from the plains. Possible additional barriers for mountain patients include lower socioeconomic status, lack of awareness of financial support, illiteracy and unfamiliarity with the hospital system. We sought to increase the rate of elective surgery for a mountain population using a patient navigation program.

Materials and methods

Patient navigators were trained to guide subjects from a mountain population through the entire hospital process for elective surgery. We compared the rate of elective operations before and after the patient navigation intervention between three groups: a control group from a mountainous area, a control group from the plains and an intervention group from a mountainous area.

Results

The baseline elective operation rate differed significantly between the plains control group, the mountain control group and the mountain intervention group (361 vs. 57 vs. 68 operations per 100,000 population per year). The rate of elective surgery between the two mountain groups was not statistically different prior to the intervention. After the intervention, the elective operation rate in the mountain group that received patient navigation increased from 68 to 131 operations per 100,000 population per year (p = 0.017).

Discussion

Patient navigation doubled the elective operation rate for a mountain population in rural Haiti. While additional barriers to access remain for this vulnerable population, patient navigation is an essential augmentation to financial assistance programs to ensure that the poor gain access to surgical care.

     

Patterns of Suicide Ideation Across Eight Countries in Four Continents During the COVID-19 Pandemic Era: Repeated Cross-sectional Study

BackgroundThe COVID-19 pandemic and countries’ response measures have had a globally significant mental health impact. This mental health burden has also been fueled by an infodemic: an information overload that includes misinformation and disinformation. Suicide, the worst mental health outcome, is a serious public health problem that can be prevented with timely, evidence-based, and often low-cost interventions. Suicide ideation, one important risk factor for suicide, is thus important to measure and monitor, as are the factors that may impact on it.ObjectiveThis investigation had 2 primary aims: (1) to estimate and compare country-specific prevalence of suicide ideation at 2 different time points, overall and by gender and age groups, and (2) to investigate the influence of sociodemographic and infodemic variables on suicide ideation.MethodsA repeated, online, 8-country (Canada, the United States, England, Switzerland, Belgium, Hong Kong, Philippines, and New Zealand), cross-sectional study was undertaken with adults aged ≥18 years, with measurement wave 1 conducted from May 29, 2020 to June 12, 2020 and measurement wave 2 conducted November 6-18, 2021. Self-reported suicide ideation was derived from item 9 of the Patient Health Questionnaire-9 (PHQ-9). Age-standardized suicide ideation rates were reported, a binomial regression model was used to estimate suicide ideation indication rates for each country and measurement wave, and logistic regression models were then employed to relate sociodemographic, pandemic, and infodemic variables to suicide ideation.ResultsThe final sample totaled 17,833 adults: 8806 (49.4%) from measurement wave 1 and 9027 (50.6%) from wave 2. Overall, 24.2% (2131/8806) and 27.5% (2486/9027) of participants reported suicide ideation at measurement waves 1 and 2, respectively, a difference that was significant (P<.001). Considerable variability was observed in suicide ideation age-standardized rates between countries, ranging from 15.6% in Belgium (wave 1) to 42.9% in Hong Kong (wave 2). Frequent social media usage was associated with increased suicide ideation at wave 2 (adjusted odds ratio [AOR] 1.47, 95% CI 1.25-1.72; P<.001) but not wave 1 (AOR 1.11, 95% CI 0.96-1.23; P=.16). However, having a weaker sense of coherence (SOC; AOR 3.80, 95% CI 3.18-4.55 at wave 1 and AOR 4.39, 95% CI 3.66-5.27 at wave 2; both P<.001) had the largest overall effect size.ConclusionsSuicide ideation is prevalent and significantly increasing over time in this COVID-19 pandemic era, with considerable variability between countries. Younger adults and those residing in Hong Kong carried disproportionately higher rates. Social media appears to have an increasingly detrimental association with suicide ideation, although having a stronger SOC had a larger protective effect. Policies and promotion of SOC, together with disseminating health information that explicitly tackles the infodemic’s misinformation and disinformation, may importantly reduce the rising mental health morbidity and mortality triggered by this pandemic.     

Fundus imaging with a nasal endoscope

Wide field fundus imaging is needed to diagnose, treat, and follow-up patients with retinal pathology. This is more applicable for pediatric patients as repeated evaluation is a challenge. The presently available imaging machines though provide high definition images, but carry the obvious disadvantages of either being costly or bulky or sometimes both, which limits its usage only to large centers. We hereby report a technique of fundus imaging using a nasal endoscope coupled with viscoelastic. A regular nasal endoscope with viscoelastic coupling was placed on the cornea to image the fundus of infants under general anesthesia. Wide angle fundus images of various fundus pathologies in infants could be obtained easily with readily available instruments and without the much financial investment for the institutes.     

Reduced basal salivary cortisol in children with asthma and allergic rhinitis

Aim: Reduced basal cortisol is reported in allergic disease. We investigated if basal salivary cortisol levels were reduced in children with asthma or allergic rhinitis, controlling for inhaled corticosteroids (ICS) use. Methods: Morning and evening saliva of asthmatic children aged 7–12 years (n = 50) and that of controls (n = 52) were sampled. A total of 19 asthmatics and four controls had allergic rhinitis. Healthy children were controls without rhinitis. Of all, 14 asthmatic children used low, and 12 used moderate or high doses of ICS. Cortisol was analysed by radioimmunoassay. Results: Morning salivary cortisol median (95% CI) was lower in asthmatics (8.7 (7.1, 9.7)) compared with that in controls (10.4 (9.6, 11.8); p = 0.006), which was similar for evening cortisol levels. Regression analyses demonstrated that asthmatics using moderate or high doses of ICS had reduced morning salivary cortisol adjusted (for age and gender) odds ratio (aOR) (95% CI) (0.54 (0.37, 0.80); p = 0.002) and reduced evening cortisol aOR (0.09 (0.01, 0.6); p = 0.02) compared with that in healthy children. Asthmatics with rhinitis on no or low doses of ICS had reduced morning cortisol aOR (0.73 (0.56, 0.96); p = 0.02) compared with that in healthy children. Conclusion: Asthmatic children on moderate or high doses of inhaled corticosteroids had reduced salivary cortisol, but co‐morbidity of asthma and rhinitis was also associated with reduced cortisol levels.     

Use of Portfolio-based Learning and Assessment in Community-based Field Curriculum

Portfolio-based learning is recognized in medical education. It helps students to assess themselves as per the key learning objectives and outcomes expected out of them. The faculty could also get feedback regarding individual student''s progress toward learning outcomes and facilitate the students achieve the same. This article addresses the process of portfolio development and assesses from students feedbacks, if portfolio-based learning is an improvement over record-based study in community-based field studies. The results of this study shows that involving students in framing objectives, developing a mechanism for self-introspection and self-assessment by the students and a mechanism by which faculty can monitor each student''s progress toward the defined objectives can significantly enhance the learnability of the students.     

Treatment of lipomas assisted with tumescent liposuction

BACKGROUND: Lipoma is a common soft-tissue tumour of mature fat cells. Although surgical excision is effective, treatments that are less invasive and not associated with disfigurement of scar would be ideal for the treatment of lipomas. Recently, tumescent liposuction has been used for the treatment of lipomas. OBJECTIVE: To evaluate the efficacy of tumescent liposuction in lipoma treatment, we reviewed our experience of lipoma treatment by tumescent liposuction. METHODS: A total of 21 patients presenting with 31 lipomas were treated with tumescent liposuction. After liposuction, remaining stromas were removed by a haemostat through the small incision. Tumour size and post-operative complications were recorded before and after treatment. RESULTS: A total of 31 lipomas of 21 patients were treated by tumescent liposuction. The size of lipomas ranged between 1.2 and 11 cm (mean size, 4.1 cm). In 23 cases, there were no complications. However, remnant lipomas, bruise, haematoma and immediate dimpling were found as complications. CONCLUSION: Tumescent liposuctions with extracting remnant fat tissue and fibrous tissue through the opening for liposuction can be an effective treatment technique in lipoma treatment in the efficacy and cosmetic outcomes and this method can be a substitute for excision in treating large lipomas.     

Effect of chymopapain on the meninges studied in an experimental model

The effect of chymopapain and contrast media in the epidural space on meninges has not been studied conclusively. The authors injected chymopapain into the epidural space of monkeys and measured the degree of arachnoid fibrosis that resulted. Animals were given injections of 1.2 mL of diatrizoate (280 mg iodine per milliliter), chymopapain (100 IU/mL), kaolin (100 mg/mL) (as a positive control), or saline (0.9%) (as a negative control). Three months later the animals were killed; the dural sac was removed intact and was fixed, sectioned, stained, and examined with light microscopy. Kaolin-treated animals developed mild to marked fibrosis of the dura. The saline- and diatrizoate-treated animals developed little or no evidence of fibrosis. One of four chymopapain-treated animals developed degenerative changes in dorsal nerve roots and fibrosis in the adjacent arachnoid. The other chymopapain-treated animals had little or no evidence of fibrosis. The studies suggest that neither diatrizoate nor chymopapain causes arachnoid fibrosis.
