RESUMO

BACKGROUND: As Artificial Intelligence and social robots are increasingly used in health and social care, it is imperative to explore the training needs of the workforce, factoring in their cultural background. OBJECTIVES: Explore views on perceived training needs among professionals around the world and how these related to country cultures. DESIGN: Cross-sectional, descriptive, mixed-methods international online survey. METHODS: Descriptive statistical analysis explored the ranking across countries and relationships with three Hofstede cultural dimensions. Thematic analysis was conducted on the open-ended text responses. RESULTS: A sample of N = 1284 participants from eighteen countries. Knowing the capabilities of the robots was ranked as the top training need across all participating countries and this was also reflected in the thematic analysis. Participants' culture, expressed through three Hofstede's dimensions, revealed statistically significant ranking differences. CONCLUSIONS: Future research should further explore other factors such as the level of digital maturity of the workplace. IMPACT STATEMENT: Training needs of health and social care staff to use robotics are fast growing and preparation should factor in patient safety and be based on the principles of person- and culture-centred care.

RESUMO

BACKGROUND: Even in developing countries like Nepal, prevalence of ST-elevation myocardial infarction has been shown to be increased with rise in prevalence of conventional risk factors like diabetes, Hypertension, smoking, dyslipidemia and obesity. Our aim is to retrospectively analyze for various risk factors and angiographic patterns of coronary artery disease in patients with ST-elevation myocardial infarction undergoing Primary Percutaneous Intervention. RESULTS: During the period of 1 year (January 2019 to December 2019), 816 patients presented to our ER with acute STEMI, among them 437 (53.6%) patients underwent primary PCI strategy and among them 22 (5.3%) patients were died. Thirty-six (4.4%) patients received thrombolysis, among them 5 (13.9%) patients were died while remaining 343 (42.0%) patients were managed conservatively and among them 20 (5.8%) were died. The mean age of patient who underwent primary PCI was 58.5±12.7 years range from 25 years to 99 years. Among them 55-75 years old 217 (49.6%) were highest in number followed by<55 years old 180 (41.2%). Males 318 (72.8%) were predominant. Among those who underwent primary PCI, hypertension 214 (49%) was the most common risk factor, followed by smoking 198 (45.3%), diabetes mellitus 123 (28.1%), dyslipidemia 53 (12.1%) and family history of premature coronary artery disease 18 (4.1%). Among those patients, 292 patients (66.8%) had single vessel disease, 99 patients (22.7%) had double vessel disease, 41 patients (9.3%) had triple vessel disease and 5 patients (1.1%) had non-significant coronary artery stenosis. Left anterior descending (53.3%) was the most frequently found culprit artery, followed by right coronary artery, left circumflex, ramus intermedius and left main artery. CONCLUSION: Fifty percent of patients presented with acute ST-elevation myocardial infarction and underwent primary PCI were between 55-75 years of age. Hypertension and smoking were the most common risk factors present in those patients. Single vessel disease was most prevalent with left anterior descending found to be the most commonly involved coronary artery followed by right coronary artery and left circumflex.

RESUMO

OBJECTIVE: Erythropoietin (EPO) is neuroprotective after asphyxia in animal studies. The efficacy and safety of EPO monotherapy in term neonates with hypoxic ischemic encephalopathy (HIE) is uncertain. STUDY DESIGN: Hundred term neonates with moderate or severe HIE were randomized by random permuted block algorithm to receive either EPO 500 U kg-1 per dose in 2 ml saline intravenously (50 neonates) on alternate days for a total of five doses with the first dose given by 6 h of age (treatment group) or 2 ml of normal saline (50 neonates) similarly for a total of five doses (placebo group) in a double-blind study. No hypothermia was given. The primary outcome was combined end point of death or moderate or severe disability at mean age of 19 months (s.d., 0.61). RESULTS: Death or moderate or severe disability occurred in 40% of neonates in the treatment group vs 70% in the placebo group (risk ratio, 0.57; 95% confidence interval (CI) 0.38 to 0.85; P=0.003). Death occurred in 16% of patients in both the groups (risk ratio, 1.0; 95% CI 0.33 to 2.9; P=0.61). The risk of cerebral palsy was lower among survivors in the treatment group (risk ratio, 0.52; 95% CI 0.25 to 1.03; P=0.04) and lesser number of babies were on anticonvulsants at assessment (risk ratio, 0.47; 95% CI 0.20 to 1.01; P=0.03). Neonatal brain magnetic resonance imaging showed more abnormalities in the placebo group (relative risk, 0.66; 95% CI 0.42 to 1.03; P=0.04)). Improvement in other neurological outcomes was not significant. CONCLUSION: EPO monotherapy reduces the risk of death or disability in term neonates with moderate or severe encephalopathy.

RESUMO

Angiogenesis, which is the process of sprouting of new blood vessels from pre-existing vessels, is vital for tumor progression. Proteolytic remodeling of extracellular matrix is a key event in vessel sprouting during angiogenesis. Urokinase type plasminogen activator receptor (uPAR) and cathepsin B are both known to be overexpressed and implicated in tumor angiogenesis. In the present study, we observed that knockdown of uPAR and cathepsin B using puPAR (pU), pCathepsin B (pC), and a bicistronic construct of uPAR and cathepsin B (pCU) caused significant inhibition of angiogenesis by disrupting the janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway-dependent expression of vascular endothelial growth factor (VEGF). Further, transcriptional suppression of uPAR and cathepsin B inhibited tumor-induced migration, proliferation of endothelial cells and decreased tumor-promoted expression of VEGF receptor-2, Rac1, gp91phox, cyclin D1, cyclin dependent kinase 4 and p-Rb in human dermal microvascular endothelial cell. Furthermore, U251 and SNB19 xenograft tissue sections from nude mice treated with pCU showed reduced expression of VEGF and CD31, which is a blood vessel visualization marker. Overall, results revealed that knockdown of uPAR and cathepsin B inhibited tumor-induced angiogenesis by disrupting the JAK/STAT pathway-dependent expression of VEGF. These data provide new insight in characterizing the pathways involved in the angiogenic cascade and for the identification of novel target proteins for use in therapeutic intervention for gliomas.

RESUMO

Left Ventricular Noncompaction (LVNC) is a genetic cardiac disease of emerging importance with a distinct clinical and pathophysiological presentation. The most common clinical manifestations include heart failure, arrhythmias and embolic events, and in children it may be associated with facial dysmorphisms and Wolff-Parkinson-White syndrome. The diagnosis of LVNC, however, is often missed, most often as a consequence of ignorance of the condition. Echocardiography is considered the reference standard for the diagnosis of LVNC. Prognosis remains poor for patients with impaired systolic left ventricular function, as treatment options are very limited. Because of the familial association of LVNC, first-degree relatives should be screened by Echocardiography.

RESUMO

This is a cross-sectional study of patients with inferior wall Myocardial Infarction (MI), who attended emergency and got admitted in ICU/CCU of TU Teaching Hospital, Maharajgunj and Bir Hospital, Kathmandu, Nepal during November 1999 to October 2000. This study was undertaken to compare the in-hospital complications and mortality of patients of inferior wall myocardial infarction with or without associated right ventricular infarction. Total 53 consecutive patients with acute inferior wall myocardial infarction were enrolled in the study. Right ventricular infarction was determined by the presence of ST elevation of more than 0.1 mv in V4R. All the patients of inferior wall myocardial infarction were divided into two groups. Group A consisted of patients of inferior wall MI with right ventricular infarction and group B consisted of patients of inferior wall MI without right ventricular infarction. In-hospital complications and mortality of group A were compared with group B. Among 20 patients of group A and 33 patients of group B, incidence of cardiogenic shock was significantly higher in patients of group A compared to group B (p=0.05). Ten patients of group A developed third degree AV Block compared to only one in group B; the incidence of which was significantly higher (p<0.001). Sinus nodal dysfunction, manifested by junctional rhythm was found in six patients of group A compared to only two patients of group B (p<0.05). Mortality was found higher in patients of group A, but it was not statistically significant. Two patients of group A expired on first day whereas only one patient of group B expired on the eighth day of admission. In hospital complications especially cardiogenic shock, complete A-V block and junctional rhythm are significantly higher in inferior wall MI when associated with RV infarction.

RESUMO

BACKGROUND: We conducted a nested case-control study in 397 rural Egyptian children <36 months of age to assess the correlation between serum levels of antibodies against toxin and colonization factors (CFs) and the risk of homologous enterotoxigenic Escherichia coli (ETEC) diarrhea. METHODS: Active case detection was performed via semiweekly home visits, and blood was obtained at 3-month intervals. After each serosurvey, case subjects were selected from children experiencing a CF antigen (CFA)/I-, CFA/II-, CFA/IV-, or heat-labile enterotoxin (LT)-ETEC diarrheal episode during the subsequent 3 months. Up to 5 control subjects per case subject were selected from children who did not experience an ETEC diarrheal episode during the corresponding interval. Serum titers of immunoglobulin G antibodies against CFA/I, coli surface antigen (CS) 3, CS6, and LT were measured by enzyme-linked immunosorbant assay. RESULTS: The distribution of serum titers of LT, CS3, and CS6 antibodies did not differ between the case and control subjects. For children <18 months of age, serum titers of CFA/I antibody were inversely related to the risk of CFA/I-ETEC diarrhea; reciprocal serum titers of CFA/I antibody > or =76 were associated with a 77% reduction in the odds of CFA/I-ETEC diarrhea. CONCLUSION: Induction of reciprocal serum titers of antibodies against CFA/I within or above the 76-186 range should be further evaluated as a predictor for assessment of the ability of candidate vaccines to protect against CFA/I-ETEC diarrhea.

RESUMO

Enterotoxigenic Escherichia coli (ETEC) causes substantial diarrheal morbidity and mortality in young children in countries with limited resources. We determined the phenotypic profiles of 915 ETEC diarrheal isolates derived from Egyptian children under 3 years of age who participated in a 3-year population-based study. For each strain, we ascertained enterotoxin and colonization factor (CF) expression, the O:H serotype, and antimicrobial susceptibility. Sixty-one percent of the strains expressed heat-stable enterotoxin (ST) only, 26% expressed heat-labile enterotoxin (LT) alone, and 12% expressed both toxins. The most common CF phenotypes were colonization factor antigen I (CFA/I) (10%), coli surface antigen 6 (CS6) (9%), CS14 (6%), and CS1 plus CS3 (4%). Fifty-nine percent of the strains did not express any of the 12 CFs included in our test panel. Resistance of ETEC strains to ampicillin (63%), trimethoprim-sulfamethoxazole (52%), and tetracycline (43%) was common, while resistance to quinolone antibiotics was rarely detected. As for the distribution of observed serotypes, there was an unusually wide diversity of O antigens and H types represented among the 915 ETEC strains. The most commonly recognized composite ETEC phenotypes were ST CS14 O78:H18 (4%), ST (or LTST) CFA/I O128:H12 (3%), ST CS1+CS3 O6:H16 (2%), and ST CFA/I O153:H45 (1.5%). Temporal plots of diarrheal episodes associated with ETEC strains bearing common composite phenotypes were consistent with discrete community outbreaks either within a single or over successive warm seasons. These data suggest that a proportion of the disease that is endemic to young children in rural Egypt represents the confluence of small epidemics by clonally related ETEC strains that are transiently introduced or that persist in a community reservoir.

RESUMO

During the period from February 1995 to February 1998, the epidemiology of Shigella diarrhea was studied among children less than three years of age residing in Egypt's Nile Delta. Children were visited twice a week and a stool sample was collected from any of them with diarrhea. The incidence of Shigella-associated diarrhea was 0.2 episodes/child-year, with S. flexneri being the most common serogroup isolated (55% of Shigella episodes). Younger age and the warm months increased the risk of developing Shigella-associated diarrhea, while breastfeeding was protective. Children with Shigella were ill for a mean of four days and passed a mean of six stools per day. Common symptoms included fever (35%), vomiting (19%), and dehydration (16%). Dysentery, however, was unusual, occurring in only 11% of the cases. In conclusion, Shigella-associated diarrhea remains relatively common in Egyptian children and supports the need for additional control measures including vaccine development.

RESUMO

OBJECTIVE: Violent media exposure has been associated with aggressive behavior, and it has been suggested that child health professionals counsel families on limiting exposure. Effective violence prevention counseling requires an understanding of norms regarding parental attitudes, practices, and influencing factors. Both theories of reasoned action and planned behavior emphasize that subjective norms and attitudes affect people's perceptions and intended behavior. Few data exist on violent television viewing and monitoring from a cross-section of families. By understanding the spectrum of parental attitudes, community-sensitive interventions for violence prevention can be developed. The objective of this study was to assess attitudes about and monitoring of violent television viewing from the perspective of parents. METHODS: An anonymous self-report assisted survey was administered to a convenience sample of parents/guardians who visited child health providers at 3 sites: an urban children's hospital clinic, an urban managed care clinic, and a suburban private practice. The parent questionnaire included questions on child-rearing attitudes and practices and sociodemographic information. RESULTS: A total of 1004 adults who accompanied children for health visits were recruited for the study; 922 surveys were completed (participation rate: 92%). A total of 830 (90%) respondents were parents and had complete child data. Of the 830 respondents, 677 had questions on television viewing included in the survey and were the focus of this analysis. Seventy-five percent of families reported that their youngest child watched television. Of these, 53% reported always limiting violent television viewing, although 73% believed that their children viewed television violence at least 1 time a week. Among television viewers, 81% reported usually or always limiting viewing of sexual content on television and 45% reported usually or always watching television with their youngest child. Among children who watched television, parents reported that they spent an average of 2.6 hours per day watching television. Limitation of television violence was associated with female parents and younger children. CONCLUSIONS: There was variability in attitudes and practices regarding television violence viewing and monitoring among parents. Attitudes and practices varied on the basis of the age of the child and the gender of the parent.

RESUMO

The incidence of enterotoxigenic Escherichia coli diarrhea among Egyptian children was 1.5 episodes per child per year and accounted for 66% of all first episodes of diarrhea after birth. The incidence increased from 1.7 episodes per child per year in the first 6 months of life to 2.3 in the second 6 months and declined thereafter.

RESUMO

Demographic indicators such as fertility rates and infant mortality rates are often measured in census surveys by interviewing mothers to obtain their pregnancy histories and child deaths. The validity of such surveys depends upon accurate recall of histories, truthful reporting of events and understanding of the questions posed. To measure the reliability of maternal reporting, two census surveys conducted in a rural Egyptian population were compared. Women between 15 and 55 years of age residing in 20 villages were asked their histories of live births, stillbirths and child deaths. An identical set of questions was posed 2 years later. Twice-monthly home visits were conducted in the intervening 2-year interval to identify accurately any new births, stillbirths and deaths occurring in the population. The maternal reports from the first census were combined with the prospectively identified births, stillbirths and deaths and compared with the maternal reports from the second census. For 1502 women, the discrepancies in the total number of births, stillbirths and child deaths reported between the two surveys were 0.6%, 4% and 0.6% respectively. However, when the consistency of responses was analysed, the proportion of women with discordant responses was 10%, 6% and 7% for the same measures. These results suggest that, despite the large number of births and deaths that women may experience in developing countries, maternal interviews provide reliable responses that can be used to estimate mortality and fertility rates in settings where vital records are incomplete or unreliable.

RESUMO

BACKGROUND: Rheumatic heart disease remains a major public health problem in developing countries with its very high prevalence. Rheumatic and congenital heart disease are significant causes of morbidity and mortality among Nepalese schoolchildren. The aim of our study was to determine the prevalence of rheumatic and congenital heart disease among schoolchildren of the Kathmandu valley in Nepal. METHODS AND RESULTS: The study included 9420 students, of whom 4466 were male and 4954 were female, with ages ranging from 5 to 18 years. A clinical survey was conducted by the examining team in selected schools, and involved answering standard questionnaires. A total of 83 children were suspected of having heart disease. Out of these 83 children, 23 were confirmed to have heart disease; 11 had rheumatic heart disease, and 12 congenital heart disease, giving a prevalence of 1.2/1000 and 1.3/1000, respectively. The commonest cardiac lesions were mitral regurgitation in the rheumatic heart disease group, and atrial septal defect in the congenital heart disease group. A higher prevalence of congenital heart disease was detected in females. CONCLUSIONS: The prevalence of rheumatic heart disease and congenital heart disease among schoolchildren of Kathmandu is 1.2/1000 and 1.3/1000, respectively, with mitral regurgitation and atrial septal defect being the commonest lesions.

RESUMO

Comparative and trend analysis was conducted on annual prevalence of antimicrobial susceptibility among Campylobacter jejuni and Campylobacter coli recovered from rural Egyptian children from 1995 through 2000. C. jejuni and C. coli demonstrated significant decreasing trends in ciprofloxacin susceptibility over the study period (p < 0.001 for both). In general, C. coli demonstrated a higher degree of susceptibility than C. jejuni, however, there was no statistical difference (p = 0.2) comparing the linear trends over the duration of the study. There was no indication of frank macrolide (erythromycin or azithromycin) resistance among any Campylobacter. Moreover, there were statistically significant positive trends in both the MIC(50) and MIC(90) values for the erythromycin and azithromycin during the study period, suggesting a possible decreasing trend in susceptibility among Campylobacter. This study demonstrated that antimicrobial susceptibility in Campylobacter has significantly decreased from 1995 through 2000 among pediatric diarrhea cases in rural Egypt.

RESUMO

The objective of this study was to describe a mass-immunization campaign of a locally-produced oral, killed whole-cell cholera vaccine in Hue city, Vietnam. Mass immunization with a 2-dose regimen of the vaccine was conducted in 13 communes in early 1998. The total, age- and sex-specific vaccine coverage was calculated using data from the vaccination records and the government census. The number of vaccine doses procured, administered, wasted, and left over, and the human and other resources required to prepare and conduct the vaccination campaign were systematically recorded. Government expenditure for planning, procurement, and delivery of the vaccine were documented. In total, 118,555 (79%) of the 49,557 targeted population were fully vaccinated during the mass-vaccination campaign. The total expenditure for the project was US dollar 105,447, resulting in a cost per fully-vaccinated person of US dollar 0.89. Mass immunization with this locally-produced oral, killed cholera vaccine was found to be feasible and affordable with attainment of high vaccination coverage.

RESUMO

BACKGROUND: Hepatitis C virus (HCV) infection and schistosomiasis are major public health problems in the Nile Delta of Egypt. To control schistosomiasis, mass treatment campaigns using tartar emetic injections were conducted in the 1960s through 1980s. Evidence suggests that inadequately sterilized needles used in these campaigns contributed to the transmission of HCV in the region. To corroborate this evidence, this study evaluates whether HCV infections clustered within houses in which household members had received parenteral treatment for schistosomiasis. METHODS: A serosurvey was conducted in a village in the Nile Delta and residents were questioned about prior treatment for schistosomiasis. Sera were evaluated for the presence of antibodies to HCV. The GEE2 approach was used to test for clustering of HCV infections, where correlation of HCV infections within household members who had been treated for schistosomiasis was the parameter of interest. RESULTS: A history of parenteral treatment for schistosomiasis was observed to cluster within households, OR for clustering: 2.44 (95% CI: 1.47-4.06). Overall, HCV seropositivity was 40% (321/796) and was observed to cluster within households that had members who had received parenteral treatment for schistosomiasis, OR for clustering: 1.76 (95% CI: 1.05-2.95). No such evidence for clustering was found in the remaining households. CONCLUSION: Clustering of HCV infections and receipt of parenteral treatment for schistosomiasis within the same households provides further evidence of an association between the schistosomiasis treatment campaigns and the high HCV seroprevalence rates currently observed in the Nile delta of Egypt.

RESUMO

Prior to the evaluation of protective efficacy, experimental vaccines conventionally undergo phase II randomized controlled clinical trials to evaluate safety and immunogenicity. Typically, an experimental vaccine is compared to another vaccine or to a placebo with respect to adverse events or immune responses, or both. Various strategies and methods are available for design and analysis of such studies. A key aspect of design is the determination of sample size. Often a sample size is chosen that gives a high probability ("power") of finding a statistically significant difference in an outcome of interest, if a difference of a specified size exists. This approach is appropriate when the primary goal of the study is to demonstrate that a difference exists between two groups or treatments. It may not, however, give adequate assurance that a confidence interval around the observed difference will be narrow enough to exclude the possibility of an unacceptably low immune response or unacceptably high adverse event frequency in recipients of the experimental vaccine. In this paper, we apply the "non-inferiority" trial design to phase II vaccine studies; that is, we design the trial to rule out a difference between the vaccine and control in immunogenicity or reactogenicity that is considered unacceptable. We also consider a setting in which the desire is to show that the difference between immune response rates for vaccine and control is greater than a specified value.
