RESUMO

BACKGROUND: Electronic clinical decision-making support systems (eCDSS) aim to assist clinicians making complex patient management decisions and improve adherence to evidence-based guidelines. Integrated management of Childhood Illness (IMCI) provides guidelines for management of sick children attending primary health care clinics and is widely implemented globally. An electronic version of IMCI (eIMCI) was developed in South Africa. METHODS: We conducted a cluster randomized controlled trial comparing management of sick children with eIMCI to the management when using paper-based IMCI (pIMCI) in one district in KwaZulu-Natal. From 31 clinics in the district, 15 were randomly assigned to intervention (eIMCI) or control (pIMCI) groups. Computers were deployed in eIMCI clinics, and one IMCI trained nurse was randomly selected to participate from each clinic. eIMCI participants received a one-day computer training, and all participants received a similar three-day IMCI update and two mentoring visits. A quantitative survey was conducted among mothers and sick children attending participating clinics to assess the quality of care provided by IMCI practitioners. Sick child assessments by participants in eIMCI and pIMCI groups were compared to assessment by an IMCI expert. RESULTS: Self-reported computer skills were poor among all nurse participants. IMCI knowledge was similar in both groups. Among 291 enrolled children: 152 were in the eIMCI group; 139 in the pIMCI group. The mean number of enrolled children was 9.7 per clinic (range 7-12). IMCI implementation was sub-optimal in both eIMCI and pIMCI groups. eIMCI consultations took longer than pIMCI consultations (median duration 28 minutes vs 25 minutes; p = 0.02). eIMCI participants were less likely than pIMCI participants to correctly classify children for presenting symptoms, but were more likely to correctly classify for screening conditions, particularly malnutrition. eIMCI participants were less likely to provide all required medications (124/152; 81.6% vs 126/139; 91.6%, p= 0.026), and more likely to prescribe unnecessary medication (48/152; 31.6% vs 20/139; 14.4%, p = 0.004) compared to pIMCI participants. CONCLUSIONS: Implementation of eIMCI failed to improve management of sick children, with poor IMCI implementation in both groups. Further research is needed to understand barriers to comprehensive implementation of both pIMCI and eIMCI. (349) CLINICAL TRIALS REGISTRATION: Clinicaltrials.gov ID: BFC157/19, August 2019.

RESUMO

BACKGROUND: Potassium permanganate (KMnO4), which is widely available, is often used by traditional health practitioners (THPs) in South Africa (SA) without taking its potentially harmful properties into account. The crystalline KMnO4 salt is sold at traditional medicine markets and shops throughout SA. However, to date, traditional uses of KMnO4 remain undocumented. OBJECTIVE: To describe KMnO4 use by THPs in KwaZulu-Natal, SA. METHODS: This sub-study is part of a larger study investigating substances used in SA traditional medicine that are collectively known as imikhando in isiZulu - literally translated as 'ore'. THPs (N=201) were interviewed in the local language (isiZulu) by trained interviewers. Information on the reasons for using/not using KMnO4, the source of information on its use and modes of administration were collected. RESULTS: KMnO4 was used as a constituent of traditional medicine by 158 (79%) THPs. Their knowledge of KMnO4 use was acquired predominantly from fellow THPs (n=134; 85%). Reasons for use included skin rash or wounds (n=99, 63%) and to treat aches, pains and swelling (n=74; 47%). The main modes of administration were in the bath (n=94; 60%), orally (n=67; 42%) and in herbal compresses (n=66; 42%). The principal reason of the 43 THPs for not administering KMnO4 was not knowing how to use it (n=29; 71%). CONCLUSIONS: This study has identified traditional medicine users at risk of manganese toxicity owing to commonly used sociocultural practices. In particular, reports of oral ingestion and use in enemas are cause for concern. This public health issue needs regulatory measures and education programmes to enlighten the population against possible harm caused by KMnO4 exposure.

RESUMO

Nowadays, 70 % of global monogastric feeds contains an exogenous phytase. Phytase supplementation has enabled a more efficient utilisation of phytate phosphorous (P) and reduction of P pollution. Trace minerals, such as iron (Fe), zinc (Zn), copper (Cu) and manganese (Mn) are essential for maintaining health and immunity as well as being involved in animal growth, production and reproduction. Exogenous sources of phytase and trace elements are regularly supplemented to monogastric diets and usually combined in a premix. However, the possibility for negative interaction between individual components within the premix is high and is often overlooked. Therefore, this initial study focused on assessing the potential in vitro interaction between inorganic and organic chelated sources of Fe, Zn, Cu and Mn with three commercially available phytase preparations. Additionally, this study has investigated if the degree of enzyme inhibition was dependent of the type of chelated sources. A highly significant relationship between phytase inhibition, trace mineral type as well as mineral source and concentration, p < 0.001 was verified. The proteinate sources of OTMs were consistently and significantly less inhibitory than the majority of the other sources, p < 0.05. This was verified for Escherichia coli and Peniophora lycii phytases for Fe and Zn, as well as for Cu with E. coli and Aspergillus niger phytases. Different chelate trace mineral sources demonstrated diversifying abilities to inhibit exogenous phytase activity.

RESUMO

A randomized controlled trial was carried out to assess the effectiveness of azithromycin versus a standard regimen with doxycycline/ciprofloxacin in the treatment of sexually transmitted infections in a resource-poor environment. Infection with Chlamydia trachomatis was cured in 23/24 (95.8%) of women in the azithromycin arm versus 19/21 (90.5%) in the doxycycline arm (P = 0.6), resulting in three treatment failures. Gonorrhoea was cured in 55/56 (98.2%) women, with one treatment failure in a patient with concomitant C. trachomatis infection. These results indicate that a single oral dose of azithromycin may prove to be a more effective and convenient treatment for sexually transmitted infections in women in a resource-poor environment

RESUMO

Yucca schidigera Roezl ex Ortgies, family Lillaceae, was fractionated with butan-1-ol to yield a butanol extractable fraction (BE; saponin fraction) and a non-butanol fraction (NBE; non-saponin fraction). Four groups of eight male rats were allowed ad libitum access to diets supplemented with water (control) or 200 mg x kg(-1) total Y. schidigera (TOT) or 200 mg x kg(-1) of each of the fractions (NBE or BE). The effects of dietary supplementation with the fractions and their interactions in TOT were analyzed according to the factorial experimental design by two-way analysis of variance. All three supplementation groups displayed significantly reduced serum urea levels (P < 0.05). The TOT and NBE fractions were found to significantly increase serum insulin levels (P < 0.01) in the absence of any fluctuations in serum glucose levels. Urea cycle enzyme activities, namely, arginase (EC 3.5.3.1) and argininosuccinate lyase (EC 4.3.2.1), were significantly decreased (P < 0.05) in vivo, although no effect was observed in vitro. Both fractions displayed effects, indicating that the active constituents are present in both fractions.

RESUMO

BACKGROUND: Dietary fish oil (FO) has been shown to modulate the immune system. The purpose of this study was to explore the effects of FO supplementation on the production of dienoic eicosanoids and cytokines in patients with human immunodeficiency virus (HIV) infection. METHODS: This was a randomized, prospective, double-blind study that included homosexual males with HIV infection. Patients were asked to consume voluntarily five food bars daily containing FO (n = 10) or safflower oil (SO) (n = 9) for 6 weeks. At baseline and week 6, plasma was obtained to measure incorporation of omega-3 fatty acids. At baseline, week 3, and week 6, measurements were made of changes in dienoic eicosanoids and cytokines from lipopolysaccharide (LPS)-stimulated peripheral blood mononuclear cells (PBMC) or spontaneously releasing cells. RESULTS: In the FO group but not the SO group, there was increased incorporation of the omega-3 fatty acid docosahexaenoic acid (DHA) into the phospholipids of the fatty acids of the plasma. In the FO group, there was a significant decrease (p = .01) in 6-keto prostaglandin (PG) F1 alpha released from PBMC. There was a significant increase (p = .01) in interleukin (IL)-6 released from the PBMC in the FO group between baseline and week 3 and between week 3 and week 6. At week 6, there was significantly more IL-6 (p = .01) released from the PBMC in the FO group compared with the SO group. There was no change in CD4 cell counts by analysis of variance. CONCLUSIONS: The FO-containing food bars were well tolerated and allowed incorporation of omega-3 fatty acids to occur. Despite evidence of significant metabolic effects on eicosanoid and cytokine production, widespread clinical use of FO for HIV-infected patients is not warranted without further study, particularly given the trend toward a decline in CD4 cell numbers at this dose and with this type of fish oil.

RESUMO

Pediatric rehabilitation is a specialty that will need more nurses in the future. A clinical rotation in this specialty was incorporated into the pediatric experience of junior-year baccalaureate nursing students at the University of Maryland School of Nursing. The experience helped students to learn more about the nursing care involved in pediatric rehabilitation, to appreciate the different disciplines within the specialty, and to view pediatric nursing from a holistic long-range perspective. The experience also strengthened ties between nursing education and practice.
