Mobile Device Usage by Gender Among High-Risk HIV Individuals in a Rural, Resource-Limited Setting.

Background: Mobile health (mHealth) is a promising tool to deliver healthcare interventions to underserved populations. We characterized the use of mobile devices in rural KwaZulu-Natal, South Africa to tailor mHealth interventions for people living with HIV and at risk for acquiring HIV in the middle-income country. Methods: We surveyed participants in community settings and offered free HIV counseling and testing. Participants self-reported their gender, age, relationship, and employment status, receipt of monthly grant, condomless sex frequency, and circumcision status (if male). Outcomes included cell phone and smartphone ownership, private data access, health information seeking, and willingness to receive healthcare messages. We performed multivariable logistic regression to assess the relationship between demographic factors and outcomes. Results: Although only 10% of the 788 individuals surveyed used the phone to seek health information, 93% of cell phone owners were willing to receive healthcare messages. Being young, female, employed, and in a relationship were associated with cell phone ownership. Smartphone owners were more likely to be young, female, and employed. Participants reporting condomless sex or lack of circumcision were significantly less likely to have private data access or to purchase data. Conclusions: mHealth interventions should be feasible in rural KwaZulu-Natal, though differ by gender. As women are more likely to own smartphones, smartphone-based mHealth interventions specifically geared to prevent the acquisition of or to support the care of HIV in young women in KwaZulu-Natal may be feasible. mHealth interventions encouraging condom use and medical male circumcision should consider the use of nonsmartphone short message service and be attuned to mobile data limitations-especially when targeting men.

Understanding the Transfer Deficit: Contextual Mismatch, Proactive Interference, and Working Memory Affect Toddlers' Video-Based Transfer.

Researchers tested the impact of contextual mismatch, proactive interference, and working memory (WM) on toddlers' transfer across contexts. Forty-two toddlers (27-34 months) completed four object-retrieval trials, requiring memory updating on Trials 2-4. Participants watched hiding events on a tablet computer. Search performance was tested using another tablet (match) or a felt board (mismatch). WM was assessed. On earlier search trials, WM predicted transfer in both conditions, and toddlers in the match condition outperformed those in the mismatch condition; however, the benefit of contextual match and WM decreased over trials. Contextual match apparently increased proactive interference on later trials. Findings are interpreted within existing accounts of the transfer deficit, and a combined account is proposed.

Systematic Quality Assessment of Published Antishivering Protocols.

Shivering is a common side effect of targeted temperature modulation and general anesthesia. Antishivering strategies often employ a stepwise approach involving both pharmacological and physical interventions. However, approaches to treat shivering are often empiric and vary widely across care environments. We evaluated the quality of published antishivering protocols and guidelines with respect to methodological rigor, reliability, and consistency of recommendations.Using 4 medical databases, we identified 4027 publications that addressed shivering therapy, and excluded 3354 due to lack of relevance. After applying predefined eligibility criteria with respect to minimal protocol standards, 18 protocols/guidelines remained. Each was assessed using a modified Appraisal of Guidelines for Research and Evaluation II (mAGREE II) instrument containing 23 quality items within 6 domains (maximal score 23). Among 18 protocols/guidelines, only 3 incorporated systematically reviewed recommendations, whereas 15 merely targeted practice standardization. Fifteen of 18 protocols/guidelines addressed shivering during therapeutic cooling in which skin counterwarming and meperidine were most commonly cited. However, their mAGREE II scores were within the lowest tertile (1 to 7 points) and the median for all 18 protocols was 5. The quality domains most commonly absent were stakeholder involvement, rigor of development, and editorial independence. Three of 18 protocols/guidelines addressed postanesthetic antishivering. Of these, the American Society of Anesthesiologists guidelines recommending forced-air warming and meperidine received the highest mAGREE II score (14 points), whereas the remaining 2 recommendations had low scores (<5 points).Current published antishivering protocols/guidelines lack methodological rigor, reliability, and strength, and even the highest scoring of the 18 protocols/guidelines fulfilled only 60% of quality items. To be consistent with evidence-based protocol/guideline development processes, future antishivering treatment algorithms should increase methodological rigor and transparency.

Associations Between Toddlers' Naturalistic Media Experience and Observed Learning from Screens.

Using secondary analysis, researchers examined associations between two-year-olds' (N = 135) naturalistic use of interactive and noninteractive media with performance on a screen-based learning task. Parents reported the number of minutes that children spent the previous day doing nine media-related activities (e.g., watching television, playing handheld videogames). The object-retrieval task required children to watch a hiding event on video and then search for the object on another screen or a real felt board. Results indicated that toddlers' naturalistic experience with interactive (but not noninteractive) media predicted their screen-based learning in the laboratory. This was true regardless of whether children were tested using interactive or noninteractive video, suggesting that using interactive media (but not watching noninteractive video) is associated with children's learning from screen media generally.

Neonatal inflammatory pain and systemic inflammatory responses as possible environmental factors in the development of autism spectrum disorder of juvenile rats.

BACKGROUND: Autism spectrum disorder (ASD) affects many children and juveniles. The pathogenesis of ASD is not well understood. Environmental factors may play important roles in the development of ASD. We examined a possible relationship of inflammatory pain in neonates and the development of ASD in juveniles. METHODS: Acute inflammation pain was induced by 5 % formalin (5 µl/day) subcutaneous injection into two hindpaws of postnatal day 3 to 5 (P3-P5) rat pups. Western blot, immunohistochemical, and behavioral examinations were performed at different time points after the insult. RESULTS: Formalin injection caused acute and chronic inflammatory responses including transient local edema, increased levels of inflammatory cytokines, TNF-α, and IL-1ß in the blood as well as in the brain, and increased microglia in the brain. One day after the pain insult, there was significant cell death in the cortex and hippocampus. Two weeks later, although the hindpaw local reaction subsided, impaired axonal growth and demyelization were seen in the brain of P21 juvenile rats. The number of bromodeoxyuridine (BrdU) and doublecortin (DCX) double-positive cells in the hippocampal dentate gyrus of P21 rats was significantly lower than that in controls, indicating reduced neurogenesis. In the P21 rat's brain of the formalin group, the expression of autism-related gene neurexin 1 (NRXN1), fragile X mental retardation 1 (FMR1), and oxytocin was significantly downregulated, consistent with the gene alteration in ASD. Juvenile rats in the formalin group showed hyperalgesia, repetitive behaviors, abnormal locomotion, sleep disorder, and distinct deficits in social memory and social activities. These alterations in neuroinflammatory reactions, gene expression, and behaviors were more evident in male than in female rats. Importantly, an anti-inflammation treatment using indomethacin (10 mg/kg, i.p.) at the time of formalin injections suppressed inflammatory responses and neuronal cell death and prevented alterations in ASD-related genes and the development of abnormal behaviors. CONCLUSIONS: These novel observations indicate that severe inflammatory pain in neonates and persistent inflammatory reactions may predispose premature infants to development delays and psychiatric disorders including ASD. The prevention of pain stimuli and prompt treatments of inflammation during development appear vitally important in disrupting possible evolution of ASD syndromes.

Touch or Watch to Learn? Toddlers' Object Retrieval Using Contingent and Noncontingent Video.

The experiment reported here was designed to examine the effect of contingent interaction with touch-screen devices on toddlers' use of symbolic media (video) during an object-retrieval task. Toddlers (24-36 months old; N = 75) were randomly assigned to watch an animated character hiding on screen either in a no-contingency video (requiring no action), a general-contingency video (accepting touch input anywhere on screen), or a specific-contingency video (requiring touch input on a particular area of interest). After the hiding event, toddlers searched for the character on a corresponding felt board. Across all trials, younger toddlers were more likely to search correctly after a specific-contingency video than after a no-contingency video, which suggests that contingent interaction designed to emphasize specific information on screen may promote learning. However, this effect was reversed for older toddlers. We interpret our findings with respect to the selective encoding of target features during hiding events and the relative strength of memory traces during search.

Toddlers' Word Learning From Contingent and Noncontingent Video on Touch Screens.

Researchers examined whether contingent experience using a touch screen increased toddlers' ability to learn a word from video. One hundred and sixteen children (24-36 months) watched an on-screen actress label an object: (a) without interacting, (b) with instructions to touch anywhere on the screen, or (c) with instructions to touch a specific spot (location of labeled object). The youngest children learned from contingent video in the absence of reciprocal interactions with a live social partner, but only when contingent video required specific responses that emphasized important information on the screen. Conversely, this condition appeared to disrupt learning by slightly older children who were otherwise able to learn words by passively viewing noninteractive video. Results are interpreted with respect to selective attention and encoding.

Efficacy of Nonpharmacological Antishivering Interventions: A Systematic Analysis.

OBJECTIVE: We performed a systematic review of the published evidence regarding nonpharmacologic antishivering interventions in various clinical settings. DATA SOURCES: Studies through November 2014 were identified using predefined search terms in electronic databases, including PubMed, the Cochrane Library, EMBASE: Excerpta Medica (Ovid), and Web of Science. STUDY SELECTION: All identified articles were critically analyzed by applying prespecified criteria. We included experimental trials with comparable baseline data investigating the antishivering efficacy of nonpharmacological interventions in subjects without underlying thermoregulatory dysfunction. DATA EXTRACTION: Sixty-five publications (3,361 subjects) were analyzed by the type of clinical setting, intervention, comparison, and study design. In addition, each study underwent a standardized study quality assessment. DATA SYNTHESIS: Nonpharmacological interventions consisted of active cutaneous warming (forced-air warming, electric heating pad/blanket, radiant heating, and water-circulating mattress), body core warming (fluid or gas warming system), passive cutaneous warming (space blankets or towels), and electroacupuncture. Identified clinical settings included perioperative settings without induced hypothermia (60 of 77 comparisons), perioperative settings with induced hypothermia (8 of 77), and induced hypothermia without anesthesia (9 of 77). Active cutaneous warming was the most commonly studied intervention, and it was associated with the highest prevalence of positive results when compared with controls in all three clinical settings. In contrast, passive cutaneous warming and body core warming showed conflicting efficacy. Comparison evaluations among different antishivering interventions were limited due to the paucity and heterogeneity of studies directly comparing different interventions against one another. CONCLUSION: This systematic review of the effectiveness of nonpharmacological antishivering methods delineates active cutaneous warming as the most effective nonpharmacologic antishivering intervention in the perioperative and induced hypothermia settings.

Fasting Plasma Glucose Levels and Longitudinal Motor and Cognitive Outcomes in Parkinson's Disease Patients.

OBJECTIVE: Hyperglycemia and diabetes mellitus have been identified as poor prognostic factors for motor and nonmotor outcomes in patients with Parkinson's disease (PD), although there is some controversy with this finding. In the present study, we investigated the effects of fasting plasma glucose (FPG) levels on longitudinal motor and cognitive outcomes in PD patients. METHODS: We included a total of 201 patients who were diagnosed with PD between January 2015 and January 2020. The patients were categorized based on FPG level into euglycemia (70 mg/dL < FPG < 100 mg/dL), intermediate glycemia (100 mg/dL ≤ FPG < 126 mg/dL), and hyperglycemia (FPG ≥ 126 mg/dL), and longitudinal FPG trajectories were analyzed using group-based trajectory modeling. Survival analysis was conducted to determine the time until motor outcome (Hoehn and Yahr stage ≥ 2) and the conversion from normal cognition to mild cognitive impairment. RESULTS: Among the patient cohort, 82 had euglycemia, 93 had intermediate glycemia, and 26 had hyperglycemia. Intermediate glycemia (hazard ratio 1.747, 95% confidence interval [CI] 1.083-2.816, p = 0.0221) and hyperglycemia (hazard ratio 3.864, 95% CI 1.996-7.481, p < 0.0001) were found to be significant predictors of worsening motor symptoms. However, neither intermediate glycemia (hazard ratio 1.183, 95% CI 0.697-2.009, p = 0.5339) nor hyperglycemia (hazard ratio 1.297, 95% CI 0.601-2.800, p = 0.5078) demonstrated associations with the longitudinal progression of cognitive impairment. Diabetes mellitus, defined by self-reported medical history, was not related to poor motor or cognitive impairment outcomes. CONCLUSION: Our. RESULTS: suggest that both impaired glucose tolerance and hyperglycemia could be associated with motor progression in PD patients.

Correlation of olfactory function factors with cardiac sympathetic denervation in Parkinson's disease.

BACKGROUND: Hyposmia is a common nonmotor symptom of Parkinson's disease (PD) and reportedly associated with dysautonomia in PD. The smell identification test for measuring olfactory function consists of multiple items to discriminate specific scents. In the present study, factor analysis of the smell identification test was performed, and the correlation of extracted factors with cardiac sympathetic denervation (CSD) in patients with PD was investigated. METHODS: The present study included 183 early PD patients who underwent the Cross-Cultural Smell Identification Test (CC-SIT) and 123I-meta-iodobenzylguanidine (123I-MIBG) myocardial scintigraphy. Factor analysis of 12 items on the CC-SIT was performed using the computed correlation matrix for the binary items, and five smell factors were extracted. Multiple linear regression was performed to determine the correlation of olfactory function with late heart-to-mediastinum (H/M) ratio of 123I-MIBG uptake. RESULTS: The mean CC-SIT score was 6.1 ± 2.6, and 133 patients (72.7%) had CSD. The CC-SIT score and five smell factors were not associated with dopamine transporter uptake or cognitive functions. However, the CC-SIT score significantly correlated with age (P < 0.001) and late H/M ratio (P < 0.001). Factors 1 and 5 showed an increasing trend with larger H/M ratio, although it was not statistically significant (ß = 0.203, P = 0.085 and ß = 0.230, P = 0.085, respectively). Factor 5 significantly correlated with the H/M ratio in PD patients with CSD (ß = 0.676, P = 0.036). DISCUSSION: The results showed olfactory dysfunction to be selectively associated with cardiac sympathetic burden in PD. The correlation of certain factors with CSD indicates the possibility of selective hyposmia in PD patients.

A novel stroke therapy of pharmacologically induced hypothermia after focal cerebral ischemia in mice.

Compelling evidence from preclinical and clinical studies has shown that mild to moderate hypothermia is neuroprotective against ischemic stroke. Clinical applications of hypothermia therapy, however, have been hindered by current methods of physical cooling, which is generally inefficient and impractical in clinical situations. In this report, we demonstrate the potential of pharmacologically induced hypothermia (PIH) by the novel neurotensin receptor 1 (NTR1) agonist ABS-201 in a focal ischemic model of adult mice. ABS-201 (1.5-2.5 mg/kg, i.p.) reduces body and brain temperature by 2-5°C in 15-30 min in a dose-dependent manner without causing shivering or altering physiological parameters. Infarct volumes at 24 h after stroke are reduced by ∼30-40% when PIH therapy is initiated either immediately after stroke induction or after 30-60 min delay. ABS-201 treatment increases bcl-2 expression, decreases caspase-3 activation, and TUNEL-positive cells in the peri-infarct region, and suppresses autophagic cell death compared to stroke controls. The PIH therapy using ABS-201 improves recovery of sensorimotor function as tested 21 d after stroke. These results suggest that PIH induced by neurotensin analogs represented by ABS-201 are promising candidates for treatment of ischemic stroke and possibly for other ischemic or traumatic injuries.

Preschoolers' attention to and learning from on-screen characters that vary by effort and efficiency: An eye-tracking study.

Prior findings are mixed regarding the extent to which children understand others' effort in early childhood. Especially, little is known about how character effort impacts children's selective attention and learning. This study examined preschoolers' visual attention to and learning from two on-screen characters: One character exerting high effort with low efficiency and another character exerting low effort with high efficiency in solving problems successfully. Children between 3.5 and 6.5 years of age (N = 70) watched a video of the two on-screen characters successfully solving problems. Children's eye movements were recorded during viewing. Each of the two on-screen characters consistently displayed either high effort/low efficiency or low effort/high efficiency to solve four problems (familiarization). For the final problem (testing), the two characters exerted the same level of effort as each other and used unique solutions to solve the problem. Children then solved the final problem themselves using real objects. Children could selectively use either character's solution demonstrated in the video. Lastly, children explicitly judged how good the characters were at solving problems. Younger children were more likely to use the solution demonstrated by the character with high effort/low efficiency, whereas older children were more likely to use the solution provided by another character with low effort/high efficiency. Younger children allocated more attention to the high effort/low efficiency character than the low effort/high efficiency character, but this pattern was modified by age such that children's gaze to the low effort/high efficiency character increased with age. Children's explicit credibility judgments did not differ by character or child age. The findings are discussed with respect to preschoolers' understanding of effort and implications for children's learning from screen media.

Prevalence and factors associated with human Taenia solium taeniosis and cysticercosis in twelve remote villages of Ranomafana rainforest, Madagascar.

BACKGROUND: Infections with the tapeworm Taenia solium (taeniosis and cysticercosis) are Neglected Tropical Diseases (NTD) highly endemic in Madagascar. These infections are however underdiagnosed, underreported and their burden at the community level remains unknown especially in rural remote settings. This study aims at assessing the prevalence of T. solium infections and associated risk factors in twelve remote villages surrounding Ranomafana National Park (RNP), Ifanadiana District, Madagascar. METHODOLOGY: A community based cross-sectional survey was conducted in June 2016. Stool and serum samples were collected from participants. Tapeworm carriers were identified by stool examination. Taenia species and T. solium genotypes were characterised by PCR and sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene. Detection of specific anti-cysticercal antibodies (IgG) or circulating cysticercal antigens was performed by ELISA or EITB/Western blot assays. PRINCIPAL FINDINGS: Of the 459 participants with paired stool and blood samples included ten participants from seven distinct villages harbored Taenia spp. eggs in their stools samples DNA sequencing of the cox1 gene revealed a majority of T. solium Asian genotype (9/10) carriage. The overall seroprevalences of anti-cysticercal IgGs detected by ELISA and EITB were quite similar (27.5% and 29.8% respectively). A prevalence rate of 12.4% of circulating cysticercal antigens was observed reflecting cysticercosis with viable cysts. Open defecation (Odds Ratio, OR = 1.5, 95% CI: 1.0-2.3) and promiscuity with households of more than 4 people (OR = 1.9, 95% CI: 1.1-3.1) seem to be the main risk factors associated with anticysticercal antibodies detection. Being over 15 years of age would be a risk factor associated with an active cysticercosis (OR = 1.6, 95% CI: 1.0-2.7). Females (OR = 0.5, 95% CI: 0.3-0.9) and use of river as house water source (OR = 0.3, 95% CI: 0.1-1.5) were less likely to have cysticercosis with viable cysts. CONCLUSIONS/SIGNIFICANCE: This study indicates a high exposure of the investigated population to T. solium infections with a high prevalence of cysticercosis with viable cysts. These data can be useful to strengthen public health interventions in these remote settings.

Touchscreens for Whom? Working Memory and Age Moderate the Impact of Contingency on Toddlers' Transfer From Video.

Toddlers exhibit poor transfer between video and real-world contexts. Contingently responsive video such as that found in touchscreen apps appears to assist transfer for some toddlers but not others. This study investigated the extent to which toddlers' working memory moderates the impact of contingency on toddler's transfer of learning from video. Toddlers (24-36 months; N = 134) watched a hiding event on either (a) contingent video that advanced only after touch input or (b) non-contingent video that proceeded automatically. Toddlers then searched for a corresponding object on a felt board. Additionally, toddlers' working memory (WM) was assessed. Findings indicate WM and age moderated the impact of contingency on transfer: Contingency decreased transfer in younger children while increasing transfer among older children. However, this was only true for children with relatively low WM. Contingency had little impact on transfer among children with relatively high WM, regardless of age. Results from this study suggest that WM is one specific moderator that predicts whether toddlers are likely to learn from contingent vs. non-contingent video, yet WM does not operate in isolation. Together, these findings underscore the importance of considering multiple child characteristics when identifying the optimal conditions for toddlers' learning from symbolic media.

Why do parents use screen media with toddlers? The role of child temperament and parenting stress in early screen use.

Considering child characteristics may be an important piece to understanding parental decision-making for children's screen use. The current cross-sectional study examined the mediating role of maternal parenting stress in the relation of child temperament to young children's screen use. Recognizing the multidimensional aspects of temperament, three mediated pathways for three temperament domains (i.e., negative affectivity, surgency, and effortful control) were tested. Mothers of toddlers, 18-36 months (N = 296), completed an online survey, reporting on child temperament, total parenting stress, and child screen use. The results showed that mother-child dynamics were related to toddlers' screen use. Toddlers' negative affectivity and effortful control were each associated with toddlers' screen use through maternal parenting stress. Higher negative affectivity was associated with higher maternal parenting stress, which in turn, was related to greater screen use in toddlers. Toddlers' lower effortful control was related to higher maternal parenting stress, which in turn, was associated with greater screen use. Toddlers' surgency was not related to either maternal parenting stress or toddlers' screen use. The findings from this study contribute to an understanding of media-related parenting in toddlerhood and may help with the development of strategies for supporting healthy media habits in families with young children.

Feasibility of a community-based delivery model for HIV pre-exposure prophylaxis among bar patrons in rural South Africa.

INTRODUCTION: South Africa, home to the world's largest HIV epidemic, has made great strides in improving access to HIV services, but specific groups, particularly young men, remain difficult to engage in the HIV care cascade. Alcohol use disorder, prevalent in South Africa, further complicates engagement. Congregate settings where alcohol is served, known as shebeens, are an ideal place to engage young people for HIV testing, treatment and prevention, including pre-exposure prophylaxis (PrEP). Here, we characterize the uptake of PrEP in shebeen patrons and explore the effect of alcohol consumption on PrEP uptake by piloting a community-based delivery model. METHODS: In the rural Kwazulu-Natal province (KZN) of South Africa, a field team made up of all men offered screenings outside of shebeens at 27 events over 6 months in 2020. Screenings included rapid HIV testing and Alcohol Use Disorder Identification Test (AUDIT). Participants who tested negative for HIV were offered PrEP as once daily oral tenofovir disoproxil fumarate/emtricitabine. Short-term retention was determined. Logistic regression was performed to identify predictors of PrEP uptake, including unadjusted and adjusted odds ratios (OR) with 95% confidence interval. RESULTS: One hundred and sixty-two shebeen patrons were screened, and 136 (84%) were eligible for PrEP. Among those eligible, 37 (27%) completed clinical evaluation and initiated PrEP. Among PrEP initiators, 91.9% were men, median age was 26.0 years (interquartile range 21-31), 32.4% were employed, 18.9% had running water and 70.3% had AUDIT scores indicating hazardous drinking. Among 37 initiators, 25 (68%) were retained at 1 month, and 19 (51%) were retained at 4 months. Independent predictors of PrEP uptake among all bar patrons, and only men (108 screened and 34 initiators), included younger age (OR 0.92 [0.88-0.97]) and lifetime number of sexual partners (OR 1.07 [1.02-1.13]). CONCLUSIONS: Community-based PrEP delivery after engagement at shebeens in rural South Africa is a feasible and novel approach to reach a traditionally difficult-to-engage population, particularly young men. In this small sample, sexual risk behaviours predicted PrEP uptake. Hazardous drinking was not a barrier to PrEP initiation.

Factors associated with low tuberculosis preventive therapy prescription rates among health care workers in rural South Africa.

BACKGROUND: Despite extensive rollout of tuberculosis preventive therapy (TPT) in South Africa to reduce the incidence of tuberculosis among people living with HIV (PWH), rates of initiation and completion have remained suboptimal. OBJECTIVE: This study aimed to identify factors associated with low TPT prescription rates among health care workers (HCWs) in rural South Africa. METHODS: A cross-sectional study was conducted using an anonymous 39-item questionnaire guided by the Consolidated Framework for Implementation Research (CFIR). HCWs from a government district hospital and 14 primary healthcare clinics (PHCs) in the rural Msinga sub-district of KwaZulu-Natal were surveyed from November 2019 to January 2020. Self-reported data on prescription rates as well as knowledge, attitudes, beliefs, and practices regarding isoniazid preventative therapy, the current TPT regimen, were obtained. Factor analysis and logistic regression were used to determine associations with low prescription rates (< 50% of PWH) for TPT prescribers, and results were placed within CFIR-driven context. RESULTS: Among 160 HCWs, the median (IQR) age was 39 (33-46) years, 76% were women, 78% worked at a PHC, and 44% had experience prescribing TPT. On multivariable analysis, prescribers (n = 71) who believed their patients would not disclose TPT use to others were significantly less likely to prescribe TPT (aOR 4.19 95% CI 1.35-13.00; p = 0.01). Inadequate isoniazid supplies trended towards significance (aOR 10.10 95% CI 0.95-106.92; p = 0.06) in association with low prescription rates. CONCLUSIONS: Strengthening HCW training to emphasize TPT prescription to all eligible PWH regardless of beliefs about patient disclosure and ensuring a consistent isoniazid supply at the health systems-level are both critical steps to enhancing TPT implementation in rural South Africa.

Drawing across media: A cross-sectional experiment on preschoolers' drawings produced using traditional versus electronic mediums.

Young children's growing access to touchscreen technology represents one of many contextual factors that may influence development. The focus of the current study was the impact of traditional versus electronic drawing materials on the quality of children's drawings during the preschool years. Young children (2-5 years, N = 73) and a comparison group of adults (N = 24) copied shapes using three mediums: marker on paper, stylus on touchscreen tablet, finger on touchscreen tablet. Drawings were later deemed codable or uncodable (e.g., scribbles), and codable drawings were then scored for subjective quality on a 4-point scale. Girls and older children (vs. boys and younger children) produced more codable drawings; however, this gap closed when children drew with their finger on a tablet. Medium also affected the quality of adults' drawings, favoring marker on paper. Thus, drawing on a tablet helped younger children produce drawings but resulted in lower quality drawings among adults. These findings underscore the importance of considering environmental constraints on drawing production. Moreover, since clinical assessments often include measures of drawing quality, and sometimes use tablet computers for drawing, these findings have practical implications for education and clinical practice.

Epidemiology of soil transmitted helminth and Strongyloides stercoralis infections in remote rural villages of Ranomafana National Park, Madagascar.

Soil-transmitted helminth (STH) infections carry the highest number of disability adjusted life years among all neglected tropical diseases, disproportionately affecting low-income countries such as Madagascar.  This study describes the epidemiology of STH and S. stercoralis infections in twelve remote villages surrounding Ranomafana National Park (RNP), Ifanadiana, Madagascar. Questionnaires and stool samples were collected from 574 subjects from random households. The Kato-Katz method and spontaneous sedimentation technique were used to examine stool samples for evidence of infection. Infection prevalence rates were 71.4% for Ascaris lumbricoides (95% CI: 67.7-75.1), 74.7% for Trichuris trichiura (95% CI: 71.1-78.2), 33.1% for hookworm (95% CI: 29.2-36.9), and 3.3% for Strongyloides stercoralis (95% CI: 1.84-4.77). Participants who were older in age (OR = 0.96; 95% CI: 0.95-0.99) and who had a high school education (OR = 0.17; 95% CI: 0.04-0.77) were less likely to be infected with a STH. Females were less likely to be infected with A. lumbricoides (OR = 0.52; 95% CI: 0.33-0.82). Participants living in villages further from the main road were more likely to be infected with a STH (F = 4.00, p = 0.02). Overall, this study found that 92.5% (95% CI: 90.3-94.6) of the people living in rural regions near RNP have at least one STH infection. This calls into question the current preventative chemotherapy (PC) program in place and suggests that further medical, socioeconomic, and infrastructural deveopments are needed to reduce STH prevalence rates among this underserved population.

Superficial Siderosis of the Central Nervous System due to Spinal Ependymoma.

A 75-year-old woman presented with a 3-year history of progressive hearing loss, gait ataxia, and cognitive impairment. Brain magnetic resonance imaging (MRI) with a time gradient echo sequence showed deposition of hemosiderin along the surface of the cerebral cortex, brainstem, and cerebellum, as well as severe atrophy in the diffuse cerebral cortex and cerebellum. We established the diagnosis of superficial siderosis of the central nervous system on the grounds of former pathognomonic MRI findings. The thoraco-lumbar spine MRI demonstrated a myxopapillary ependymoma in the T11-L2 spinal canal that was considered to be the cause of a chronic subarachnoid hemorrhage, affecting the leptomeninges and subpial layers of the central nervous system.
