Feeding tube use and complications in Prader-Willi syndrome: Data from the Global Prader-Willi Syndrome Registry.

Guidance on indications for, and types of, feeding tubes recommended in Prader-Willi syndrome (PWS) is needed. A Global PWS Registry survey was developed to investigate nasogastric (NG) and gastrostomy (G) tube use and associated complications. Of 346 participants, 242 (69.9%) had NG-tubes, 17 (4.9%) had G-tubes, and 87 (25.1%) had both NG- and G-tubes. Primary indication for placement was "feeding difficulties and/or poor weight gain" for both NG- (90.2%) and G-tubes (71.2%), while "aspiration/breathing difficulties" was the procedural indication for 6.4% of NG-tubes and 23.1% of G-tubes. NG-tubes were generally removed by age 6 months (NG Only: 82.9%; NG/G: 98.8%), while G-tubes were often removed by age 2 years (G Only: 85.7%; NG/G: 70.5%). The severe complication rate from G-tubes was 31.7% and from NG-tubes was 1.2%. Overall, caregivers indicated the presence of an NG- or G-tube had a positive effect on quality of life. Feeding difficulties in PWS are largely managed by NG-tube alone. The severe complication rate from G-tubes was about 25 times higher than from NG-tubes; yet, G-tube placement rates have generally increased. G-tube placement puts individuals with PWS at risk for anesthesia and surgery-related complications and should be considered judiciously by a multidisciplinary team.

The activities of suaveolol and other compounds from Hyptis suaveolens and Momordica charantia against the aetiological agents of African trypanosomiasis, leishmaniasis and malaria.

African trypanosomiasis and malaria are among the most severe health challenges to humans and livestock in Africa and new drugs are needed. Leaves of Hyptis suaveolens Kuntze (Lamiaceae) and Momordica charantia L. (Cucurbitaceae) were extracted with hexane, ethyl acetate, and then methanol, and subjected to silica gel column chromatography. Structures of six isolated compounds were elucidated through NMR and HR-EIMS spectrometry. Callistrisic acid, dehydroabietinol, suaveolic acid, suaveolol, and a mixture of suaveolol and suaveolic acid (SSA) were obtained from H. suaveolens, while karavilagenin D and momordicin I acetate were obtained from M. charantia. The isolated biomolecules were tested against trypomastigotes of Trypanosoma brucei brucei and T. congolense, and against Plasmodium falciparum. The most promising EC50 values were obtained for the purified suaveolol fraction, at 2.71 ± 0.36 µg/mL, and SSA, exhibiting an EC50 of 1.56 ± 0.17 µg/mL against T. b. brucei trypomastigotes. Suaveolic acid had low activity against T. b. brucei but displayed moderate activity against T. congolense trypomastigotes at 11.1 ± 0.5 µg/mL. Suaveolol and SSA were also tested against T. evansi, T. equiperdum, Leishmania major and L. mexicana but the antileishmanial activity was low. Neither of the active compounds, nor the mixture of the two, displayed any cytotoxic effect on human foreskin fibroblast (HFF) cells at even the highest concentration tested, being 200 µg/mL. We conclude that suaveolol and its mixture possessed significant and selective trypanocidal activity.

SEROEPIDEMIOLOGY OF HBV ANTIGEN AND ANTI-HCV AMONG GENERAL POPULATION IN A RURAL LOCAL IN BAUCHI STATE, NIGERIA.

Background: HBV and HCV infections are a significant public health issue in developing countries with weak healthcare systems, high poverty rates, illiteracy, low HBV immunization coverage, and low public health education. A study assessed the sero epidemiology of HBV antigen, anti- HCV markers, biochemical and heamatological indices of 559 participants in Dambam local government during hepatitis day. A structured questionnaire was administered to assess demographic information and risk factors. Rapid latex immunochromtographic kits were used for HBV, HCV, and HBV Combo serological markers, with positive and negative control included in each batch analysis. Descriptive statistics analysis was conducted on the data. Results: The 559 study participants, had a mean age of 35.5+10.9years, majority within the age- group, 18-39years 279(49.04%), female accounted for 291(52.1%) compared to male 268(47.9), educational background, tertiary 244(43.6%), married, 356(68.7%) and student were 254(45.4%). Seroprevalence of HBsAg was 10.7%, serological markers as follows, HbsAb 1.7%, HbeAg 13.3%, HbeAb 60.0% HbcAb 95.0% and Anti-HCV of 3.4%. Gender breakdown(M vs F) of HBV(13.4% vs 8.2%) and HCV(3.0% vs 3.8%). Significant association was observed in the seroprevalence of HBV and HCV with age-group, gender, marital status and occupation(<0.05). No significant difference was observed with the risk factors of HBV and HCV. Biochemical and heamatological indices showed a significant difference between seropositive and negative study participants(<0.05). Conclusion: The study's findings affirmed the endemicity of HBV infection and the increasing trend of HCV infection in Bauchi state, posing serious public health concerns. HBV serological markers suggest a low HBV immunization coverage rate and exposure of participants to the viral etiology in the community. Strengthening immunization coverage and population-based surveillance is strategic in the prevention and control of viral hepatitis in Bauchi state.

Correlation between Echocardiographic Left Ventricular Hypertrophy and various Electrocardiographic Criteria of Left Ventricular Hypertrophy among Black Hypertensives.

BACKGROUND: Systemic hypertension remains an important risk factor for cardiovascular diseases and a major global public health problem. Left ventricular hypertrophy (LVH) is a recognized complication of systemic hypertension and strongly predicts cardiovascular morbidity and mortality. In Nigeria, few studies have evaluated the correlation of ECG criteria in the diagnosis of left ventricular hypertrophy among hypertensives and almost all the previous studies on ECG LVH used only one or two criteria. This study sets out to determine the correlations between various ECG criteria of LVH and echocardiographic LVH among patients with hypertension using six ECG LVH criteria. METHODS: One hundred and seventy-eight hypertensives and eighty- nine age and sex matched controls were recruited consecutively into the study. All participants including hypertensives and control subjects had echocardiography whereas only hypertensive subjects had both echocardiography and ECG. ECG LVH was determined using Sokolow-Lyon, Cornell voltage, Goldberger, Massoleini, Romhilt-Estes and Cornell duration product ECG criteria. RESULTS: Sokolow-Lyon and Cornell voltage criteria had significant positive correlation with echocardiographic LVH (p=0.001 and 0.003, respectively). Although Goldberger and Massoleini criteria had positive correlation coefficients, these were not statistically significant. CONCLUSION: There are significant correlations between echocardiographic LVH and ECG LVH determined by Cornell voltage and Sokolow-Lyon criteria.

CONTEXTE: L'hypertension systémique reste un facteur de risque important pour les maladies cardiovasculaires et un problème majeur de santé publique mondiale. L'hypertrophie ventriculaire gauche (HVG) est une complication reconnue de l'hypertension systémique et prédit fortement la morbidité et la mortalité cardiovasculaires. Au Nigeria, peu d'études ont évalué la corrélation des critères ECG dans le diagnostic de l'hypertrophie ventriculaire gauche chez les hypertendus et presque toutes les études précédentes sur l'ECG HVG n'utilisaient qu'un ou deux critères. Cette étude vise à déterminer les corrélations entre divers critères ECG de l'HVG et l'HVG échocardiographique chez les patients hypertendus à l'aide de six critères ECG LVH. MÉTHODES: Cent soixante-dix-huit hypertendus et quatre-vingtneuf témoins appariés selon l'âge et le sexe ont été recrutés consécutivement dans l'étude. Tous les participants, y compris les hypertendus et les sujets témoins, ont eu une échocardiographie alors que seuls les sujets hypertendus ont eu à la fois une échocardiographie et un ECG. ECG L'HVG a été déterminée en utilisant les critères ECG de produit de durée de Sokolow-Lyon, de tension de Cornell, de Goldberger, de Massoleini, de Romhilt-Estes et de Cornell. RÉSULTATS: Les critères de tension de Sokolow-Lyon et de Cornell avaient une corrélation positive significative avec l'HVG échocardiographique (p=0,001 et 0,003, respectivement). Bien que les critères de Goldberger et Massoleini aient des coefficients de corrélation positifs, ceux-ci n'étaient pas statistiquement significatifs. CONCLUSION: Il existe des corrélations significatives entre l'HVG échocardiographique et l'HVG ECG déterminées par le voltage de Cornell et les critères de Sokolow-Lyon. MOTS-CLÉS: Corrélation; échocardiographie; électrocardiographie; Hypertrophie ventriculaire gauche; Hypertendus noirs.

Body Mass Index Is a Better Indicator of Body Composition than Weight-for-Length at Age 1 Month.

OBJECTIVE: To assess whether body mass index (BMI) provides a better assessment of measured adiposity at age 1 month compared with weight-for-length (WFL). STUDY DESIGN: Participants were healthy term-born infants in the Infant Growth and Microbiome (n = 146) and the Baby Peas (n = 147) studies. Length, weight, and body composition by air displacement plethysmography were measured at 1 month. World Health Organization-based WFL and BMI z-scores were calculated. Within-cohort z-scores of percent fat-Z, fat mass-Z, fat mass/length2-Z, fat mass/length3-Z, fat-free mass-Z, and fat-free mass/length2-Z were calculated. Correlation and multiple linear regression (adjusted for birth weight) analyses tested the associations between body composition outcomes and BMI-Z vs WFL-Z. Quantile regression was used to test the stability of these associations across the distribution of body compositions. RESULTS: The sample was 52% female and 56% African American. Accounting for birth weight, both BMI-Z and WFL-Z were strongly associated with fat mass-Z (coefficients 0.56 and 0.35, respectively), FM/L2-Z (0.73 and 0.51), and FM/L3-Z (0.79 and 0.58), with stronger associations for BMI-Z compared with WFL-Z (P < .05). Even after accounting statistically for birth weight, BMI-Z was persistently more strongly associated than WFL-Z with body composition outcomes across the distribution of body composition outcomes. CONCLUSIONS: We demonstrate in 2 distinct cohorts that BMI is a better indicator of adiposity in early infancy compared with WFL. Our findings support the preferred use of BMI for growth and nutritional status assessment in infancy.

Comparison of QuantiFERON-TB Gold In-Tube (QFT-GIT) and tuberculin skin test (TST) for diagnosis of latent tuberculosis in haemodialysis (HD) patients: a meta-analysis of κ estimates.

Diagnosis of latent tuberculosis infection (LTBI) is a concern in haemodialysis (HD) patients. Many studies have compared QuantiFERON-TB Gold In-Tube (QFT-GIT) and tuberculin skin test (TST) for detecting LTBI and reported the κ statistic of agreement between QFT-GIT and TST in HD patients. The present study aimed to systematically review this literature and conduct meta-analysis of individual studies that estimated the κ between QFT-GIT with TST among HD patients. All relevant published studies that were available as full-text were obtained by searching Medline (1950), Web of Sciences (1945), Scopus (1973) through May 2016. The κ was re-estimated from the individual studies and pooled using random effect meta-analysis. Subgroup analysis and meta-regression were applied to evaluate the effect of Bacillus Calmette-Guérin (BCG) vaccination, TST cut-off points, quality of studies, sample size and age on variation of κ estimate. Eight studies involving 901 HD patients were included in meta-analysis. The pooled κ estimate was 0·28 (I 2 = 18·4%, P = 0·239, 95% confidence intervals 0·22-0·34). The discordance of TST-/QFT-GIT+ was more than TST+/QFT-GIT-. History of BCG vaccination, TST cut-off points and age are related to variation of κ estimates. TST and QFT-GIT are not comparable in detecting LTBI in HD patients. The higher TST-/QFT-GIT+ ratio compared with TST+/QFT-GIT- ratio, may indicate the superiority of QFT-GIT over TST for detection LTBI in HD patients.

Iatrogenic Necrolytic Migratory Erythema in an Infant with Congenital Hyperinsulinism.

Necrolytic migratory erythema (NME) is a rare cutaneous finding characterized by painful, pruritic, scaly red patches and plaques, bullae, and superficial erosions. Typically NME is a paraneoplastic phenomenon associated with glucagonoma. We report the exceptional case of an infant who developed iatrogenic NME arising secondary to glucagon therapy for congenital hyperinsulinism.

Acardius Acephalus in an Undiagnosed Twin Gestation; Case Report and review of Literature from Federal Medical Centre Gusau, Zamfara State, Northwestern Nigeria.

BACKGROUND: Acardiusacephalusfoetal anomaly is a rare abnormality occurring in multifoetal gestation particularly monozygous twin gestation. It is commonly characterized by varying gross structural malformations incompatible with extra uterine life. Reports on acardiusacephalusfoetal anomaly remain sparse. We report a case of acardiusacephalusin an undiagnosed twin with striking gross malformation delivered to a 28 year old un-booked multipara. Objective To report an acardiusacephalic anomaly in the second of an undiagnosed twin pregnancy delivered to a multipara and review relevant literature. METHOD: A Case was fully documentedat the Federal medical centre Gusau, Nigeria and local and international literature search conducted and reviewed. CONCLUSION: Acardiusacephalus may have additional malformations in the other organs. The current case, the first in our centre, shows yet other striking gross and severe malformations characterizing acardiusacephalus.

Family caregiver outcomes after participating in a hospital-based family involvement program after major gastrointestinal surgery: a subgroup analysis of a patient preferred cohort study.

BACKGROUND: Engaging families in postsurgical care is potentially beneficial for improving cancer patient outcomes and quality of care. The authors developed a family involvement program (FIP) and in this study, the authors aim to evaluate the impact of the FIP on family caregiver burden and well-being. Moreover, the authors aim to assess the fidelity of the program. MATERIALS AND METHODS: This is a preplanned subgroup analysis of a patient-preferred prospective cohort study that included family caregivers of patients who underwent major oncological surgery for gastrointestinal tumors. Only patient-nominated family caregivers could participate in the FIP. Caregivers received structured training in fundamental caregiving tasks from healthcare professionals and then actively participated in these tasks. Caregiver burden and well-being were measured four times (at hospital admission, at hospital discharge, and at 1 and 3 months posthospital discharge) using the Caregiver Strain Index+ (CSI+) and the Care-related Quality of Life instrument (CarerQoL-7D). The fidelity of the FIP was assessed by recording completion of care activities. In addition, family caregivers were asked whether they would participate in the FIP again. RESULTS: Most of the 152 family caregivers were female (77.6%), and their mean age was 61.3 years (SD=11.6). Median CSI+ scores ranged between -1 and 0 and remained below the cutoff point of experiencing burden. CarerQoL-7D results indicated no significant differences in family caregivers' well-being over time. Upon discharge, over 75% of the family caregivers stated that they would recommend the FIP to others. The highest compliance with all fundamental care activities was observed during postoperative days 2-4. CONCLUSION: The family caregivers of oncological surgical patients who participated in the FIP exhibited acceptable levels of caregiver burden and well-being. These findings suggest that the FIP is a valuable intervention to equip family caregivers with the skills to navigate the uncertain period following a patient's hospital discharge.

Surgical outcomes in surgical oncology patients who participated in a family involvement program.

BACKGROUND: There is a lack of evidence regarding the relationship between family involvement and outcomes in gastrointestinal oncology patients after surgery. To evaluate the effect of a family involvement program for patients undergoing oncologic gastrointestinal surgery on unplanned readmissions within 30 days after surgery. METHODS: A multicenter patient-preference cohort study compared 2 groups: patients who participated in the family involvement program versus usual care. The program comprised involvement of family caregivers in care and training of health care professionals in family-centered care. Multivariable regression analyses were used to evaluate the effect of the FIP on the number of unplanned readmissions up to 30 days after surgery. Secondary outcomes included complications sensitive to fundamental care activities, emergency department visits, intensive care unit admissions, hospital length of stay, and the need for professional home care after discharge. RESULTS: Of the 301 patients included, 152 chose the family involvement program, and 149 chose usual care. Postoperative readmissions occurred in 25 (16.4%) patients in the family involvement program group, and 15 (10.1%) in the usual care group (P = .11). A significant reduction of 16.2% was observed in the need for professional home care after discharge in the family involvement program group (P < .01). No significant differences were found between the 2 groups in the other secondary outcomes. CONCLUSION: The family involvement program did not reduce the number of unplanned readmissions, but it led to a substantial reduction in-home care, which suggests an economic benefit from a societal perspective. Implementation of the family involvement program should, therefore, be considered in clinical practice.

Maculatin 1.1 disrupts Staphylococcus aureus lipid membranes via a pore mechanism.

Maculatin 1.1 (Mac1) showed potent activity against Staphylococcus aureus with an MIC of 7 µM. The mode of action of Mac1 was investigated by combining assays with S. aureus cells and lipid vesicles mimicking their membrane composition. A change in Mac1 conformation was monitored by circular dichroism from random coil to ca. 70% α-helix structure in contact with vesicles. Electron micrographs of S. aureus incubated with Mac1 showed rough and rippled cell surfaces. An uptake of 65% of small (FD, 4 kDa [FD-4]) and 35% of large (RD, 40 kDa [RD-40]) fluorescent dextrans by S. aureus was observed by flow cytometry and indicate that Mac1 formed a pore of finite size. In model membranes with both dyes encapsulated together, the full release of FD-4 occurred, but only 40% of RD-40 was reached, supporting the flow cytometry results, and indicating a pore size between 1.4 and 4.5 nm. Finally, solid-state nuclear magnetic resonance showed formation of an isotropic phase signifying highly mobile lipids such as encountered in a toroidal pore structure. Overall, Mac1 is a promising antimicrobial peptide with the potent capacity to form pores in S. aureus membranes.

Splenectomy in children with "mild" hereditary spherocytosis.

Splenectomy is considered the treatment of choice for patients with "symptomatic" hereditary spherocytosis (HS). Published guidelines offering recommendations for splenectomy in HS categorize patients primarily based on hemoglobin concentration. We performed a retrospective review of 64 children having splenectomy for HS at Children's Medical Center Dallas. On the basis of hemoglobin concentration alone, 16 children (25%) had mild, 38 (59%) moderate, and 10 (16%) severe HS. However, when reticulocyte count was used to categorize disease severity, only 3 patients (5%) having splenectomy would be considered mild, 17 (27%) moderate, and 42 (66%) severe. Despite otherwise having "mild" disease defined by near-normal hemoglobin levels, many children with nontraditional or subjective signs and symptoms related to hemolytic rate received a splenectomy, and, therefore, reticulocyte count might be a more reliable laboratory marker suggesting consideration of splenectomy. A validated assessment tool incorporating quality of life indicators in addition to the traditional medical indications for splenectomy in HS would be valuable in assessing indications for the procedure.

Assessing the readiness to integrate tobacco control in medical curriculum: experiences from five medical colleges in Southern India.

BACKGROUND: Making tobacco cessation a normative part of all clinical practice is the only way to substantially reduce tobacco-related deaths and the burden of tobacco-related morbidity in the short term. This study was undertaken because information on receptivity to integrate tobacco control education in the medical curriculum is extremely limited in low- and middle-income countries. METHODS: From five medical colleges (two government) in southern India, 713 (men 59%) faculty and 2585 (men 48%) students participated in our cross-sectional survey. Information on self-reported tobacco use and readiness to integrate tobacco control education in the medical curriculum was collected from both the faculty and students using a pretested structured questionnaire. Multiple logistic regression analysis was done to find the associated factors. RESULTS: Current smoking was reported by 9.0% (95% CI 6.6-12.1) of men faculty and 13.7% (CI 11.8-15.9) by men students. Faculty who were teaching tobacco-related topics [odds ratio (OR) 2.29; 95% CI 1.65-3.20] compared to those who were not, faculty in government colleges (OR 1.69; CI 1.22-2.35) compared to those in private colleges and medical pecialists (OR 1.79; CI 1.23-2.59) compared to surgical and non-clinical specialists were more likely to be ready to integrate tobacco control education in the medical curriculum. Non-smoking students (OR 2.58; CI 2.01-3.33) compared to smokers, and women students (OR 1.80; CI 1.50-2.17) compared to men were more likely to be ready to integrate a tobacco control education in the curriculum. CONCLUSION: Faculty and students are receptive to introduce tobacco control in the medical curriculum. Government faculty, medical specialists and faculty who already teach tobacco-related topics are likely to be early introducers of this new curriculum.

Synchronous Primary Parosteal Osteosarcoma and Primary Mediastinal Germ Cell Tumour with Atypical Mycobacterial Infection - A Rare Phenomenon: A Case Report.

Mediastinal germ cell tumours are a rare group of extragonadal germ cell tumours with less than 5% prevalence of all germ cell tumours. Primary mediastinal germ cell tumours themselves account for 16-36% of the extragonadal germ cell tumours. Along the spectrum of osteosarcoma, parosteal osteosarcoma is a well-differentiated surface osteosarcoma with a prevalence of 4% of all osteosarcoma. As such synchronous primary parosteal osteosarcoma and primary mediastinal germ cell tumour are exceedingly rare. This leads to complexity in determining the most appropriate chemotherapy for two different types of tumours and its potential side effects of reduced immunity leading to potential secondary infection. Here we report a case of a 16-year-old boy who presented with synchronous primary osteosarcoma and primary mediastinal germ cell tumour, complicated with atypical mycobacterial infection post-operatively. Additionally, we discuss our choice of chemotherapy and the management of the atypical mycobacterial infection.

Urinary proteomics combined with home blood pressure telemonitoring for health care reform trial-First progress report.

High blood pressure (BP) and type-2 diabetes (T2DM) are forerunners of chronic kidney disease and left ventricular dysfunction. Home BP telemonitoring (HTM) and urinary peptidomic profiling (UPP) are technologies enabling risk stratification and personalized prevention. UPRIGHT-HTM (NCT04299529) is an investigator-initiated, multicenter, open-label, randomized trial with blinded endpoint evaluation designed to assess the efficacy of HTM plus UPP (experimental group) over HTM alone (control group) in guiding treatment in asymptomatic patients, aged 55-75 years, with ≥5 cardiovascular risk factors. From screening onwards, HTM data can be freely accessed by all patients and their caregivers; UPP results are communicated early during follow-up to patients and caregivers in the intervention group, but at trial closure in the control group. From May 2021 until January 2023, 235 patients were screened, of whom 53 were still progressing through the run-in period and 144 were randomized. Both groups had similar characteristics, including average age (62.0 years) and the proportions of African Blacks (81.9%), White Europeans (16.7%), women 56.2%, home (31.2%), and office (50.0%) hypertension, T2DM (36.4%), micro-albuminuria (29.4%), and ECG (9.7%) and echocardiographic (11.5%) left ventricular hypertrophy. Home and office BP were 128.8/79.2 mm Hg and 137.1/82.7 mm Hg, respectively, resulting in a prevalence of white-coat, masked and sustained hypertension of 40.3%, 11.1%, and 25.7%. HTM persisted after randomization (48 681 readings up to 15 January 2023). In conclusion, results predominantly from low-resource sub-Saharan centers proved the feasibility of this multi-ethnic trial. The COVID-19 pandemic caused delays and differential recruitment rates across centers.

Antinociceptive Activity of Methanol Extract of Muntingia calabura Leaves and the Mechanisms of Action Involved.

Muntingia calabura L. (family Elaeocarpaceae) has been traditionally used to relieve various pain-related ailments. The present study aimed to determine the antinociceptive activity of methanol extract of M. calabura leaves (MEMC) and to elucidate the possible mechanism of antinociception involved. The in vivo chemicals (acetic acid-induced abdominal constriction and formalin-, capsaicin-, glutamate-, serotonin-induced paw licking test) and thermal (hot plate test) models of nociception were used to evaluate the extract antinociceptive activity. The extract (100, 250, and 500 mg/kg) was administered orally 60 min prior to subjection to the respective test. The results obtained demonstrated that MEMC produced significant (P < 0.05) antinociceptive response in all the chemical- and thermal-induced nociception models, which was reversed after pretreatment with 5 mg/kg naloxone, a non-selective opioid antagonist. Furthermore, pretreatment with L-arginine (a nitric oxide (NO) donor), N(G)-nitro-L-arginine methyl esters (L-NAME; an inhibitor of NO synthase (NOS)), methylene blue (MB; an inhibitor of cyclic-guanosine monophosphate (cGMP) pathway), or their combination also caused significant (P < 0.05) change in the intensity of the MEMC antinociception. In conclusion, the MEMC antinociceptive activity involves activation of the peripheral and central mechanisms, and modulation via, partly, the opioid receptors and NO/cGMP pathway.
