ESTABLISHING RELIABILITY AND VALIDITY OF AN INSTRUMENT MEASURING JORDANIAN MUSLIM WOMEN'S CONTRACEPTIVE BELIEFS

We tested the psychometric properties of an instrument entitled intention to use oral contraceptive tool (IUOCT). This instrument was developed to evaluate Jordanian Muslim women's intention to use oral contraceptives (OCs). We used the theory of planned behavior (TPB) as a conceptual framework for developing the IUOCT. The internal consistency of the IUOCT ranged from .70 to .94. The stability of IUOCT ranged from .79 to .85. Factor analysis identified four factors that represented the three constructs of the TPB. The known-group technique showed significant difference between past users and nonpast users of OCs. The predictive validity analysis showed that each scale contributed to the variability in the intention.     

Septicaemia and meningitis with campylobacter fetus subspecies intestinalis

Summary Two cases of infection with Campylobacter fetus subspecies intestinalis are reported. In a 46-year-old farmer the development of septicaemic campylobacteriosis with acute gastroenterocolitis was favoured by malnutrition due to chronic alcoholism. After treatment with erythromycin the patient recovered completely. The second patient, a 40-year-old worker with meningitis, recovered after combined streptomycin-erytromycin therapy. In both patients antibiodies against homologous and reference strains of Campylobycter fetus subspecies intestinalis, serotype 1 (Mitscherlich) were demonstrated in titres ranging from 1 : 16 to 1 : 64 by type the complement-fixation test.

Sepsis und Meningitis durch Campylobacter fetus Subspezies intestinalis

Zusammenfassung Zwei Fälle von Campylobacter fetus-Infektion mit Sepsis und Meningitis wurden beobachtet. Bei einem 46jährigen Bauern wurde eine septische Campylobacteriosis durch extreme Mangelernährung infolge von chronischem Alkoholismus begünstigt. Die Therapie mit Erythromycin war erfolgreich. Der andere Patient war ein 40jähriger Arbeiter mit Meningitis; auch dieser hat nach einer kombinierten Erythromycin- und Streptomycinkur das Krankenhaus gesund verlassen. Das Serumantikörpertiter war 1 : 16 bis 1 :64 in der Komplementbindungsreaktion gegen Homologe und Referenzstämme der Campylobacter fetus subspecies intestinalis serotype I (Mitscherlich).

     

Prevalence of tuberculosis infection and its relationship to stunting in children (under five years) household contact with new tuberculosis cases

BackgroundChildren who inhabit the same house with tuberculosis (TB) patients are at high risk for infection and illness with TB. Nutritional status (stunting) in children is related to the child's ability to withstand MTB (Mycobacterium Tuberculosis). This study aims to estimated the prevalence of tuberculosis infection and its relationship to stunting in children (under five years) with household contact (HHC) with new TB cases.MethodsA cross-sectional design was implemented. Conducted in July 2018–April 2019 at 13 Public Health Center in Makassar City. The sample size was calculated using one sample situation-about precision formula. Samples were children under five who had contact with new diagnosed TB cases. Tuberculosis infection was measured by TST (tuberculin skin test). Logistic regression with causal model to examine TB infection relationship with stunting and covariate variable, analyzed using Stata/MP 13.0 software.ResultsOne hundred twenty-six (126) eligible children. Prevalence of tuberculosis infection was 38.10%. Frequency of stunted was 31 children (24.60%). Stunted nutritional status (aPR): 2.36, 95% CI 1.60–3.44), boys (aPR: 1.47, 95% CI 0.96–2.25), not getting BCG immunization (aPR: 1.58, 95%) CI 0.89–2.82), and high contact intensity (aPR: 2.62, 95% CI 1.10–6.22) best predicted the tuberculosis infection in children with TB case household contacts with a model contribution of 64%.ConclusionStunted nutritional status (moderate and severe), boys, not getting BCG immunization, and high contact intensity are the determinants of TB infection transmission in children HHC with TB. Children under five years of age who have close contact with TB cases should be targeted for priority interventions to prevent the transmission of TB infection and progressing to TB cases.     

Acetaminophen toxicity up-regulates MRP2 expression in the liver of cats: an old story with new vision

This study was conducted to clarify the role of efflux transporter MRP₂ in acetaminophen-induced hepatotoxicity in cats. Sixteen mixed bred male cats and four liver samples from mixed breed male dogs were used. The cats were assigned into four groups (n?=?4), received saline and 2, 10 and 50?mg/kg doses of acetaminophen orally for 14 days. Unlike the intact dogs, the MRP₂ was not detectable in control cats. MRP₂ at mRNA level was expressed in the liver of cats, which received the medium and high doses. Data suggest that the MRP₂ expression may involve in the acetaminophen-induced hepatotoxicity in cats.

Flixweed vs. Polyethylene Glycol in the Treatment of Childhood Functional Constipation: A Randomized Clinical Trial

Background:

Polyethylene glycol (PEG) is often considered as the first-line treatment for functional constipation in children. Descurainia sophia (L.) Webb et Berth (D. sophia) is a safe recommended medicine in Iranian folk and Traditional Persian Medicine for the treatment of constipation.

Objectives:

To clinically compare D. sophia with PEG 4000 (without electrolyte) in pediatric constipation and to assess its efficacy and side effects.

Patients and Methods:

120 patients aged 2 - 12 years with constipation for at least 3 months were included in an 8 weeks lasting randomized controlled trial within two parallel-groups. Children received either PEG, 0.4 g/kg/day, or D. sophia seeds, 2 grams (for children aged 2 - 4 years) and 3 grams (for those aged > 4 years) per day.

Results:

A total of 109 patients completed the study (56 in D. sophia and 53 in PEG group). At the end of the study, 36 (64.3%) patients in D. sophia group and 29 (54.7%) in PEG group were out of Rome III criteria (P = 0.205). Median weekly stool frequency in 0, 1, 2, 3 weeks of the treatment was found to be 2, 5, 5, 5 in D. sophia and 3, 4, 4, 5 in PEG group (P = 0.139, 0.076, 0.844, 0.294), respectively. The number of patients who suffered flatulence was less (5, 8.9%) in D. sophia group as compared to PEG group (6, 11.3%) at the end of the trial (P = 0.461). D. sophia taste was less tolerated.

Conclusions:

D. sophia is introduced as a cheap and available medication which can be applied as a safe alternative to conventional PEG in the management of pediatric chronic functional constipation.     

Enhanced electron transfer mediated detection of hydrogen peroxide using a silver nanoparticle–reduced graphene oxide–polyaniline fabricated electrochemical sensor

The current study aims at the development of an electrochemical sensor based on a silver nanoparticle–reduced graphene oxide–polyaniline (AgNPs–rGO–PANI) nanocomposite for the sensitive and selective detection of hydrogen peroxide (H₂O₂). The nanocomposite was fabricated by simple in situ synthesis of PANI at the surface of rGO sheet which was followed by stirring with AEC biosynthesized AgNPs to form a nanocomposite. The AgNPs, GO, rGO, PANI, rGO–PANI, and AgNPs–rGO–PANI nanocomposite and their interaction were studied by UV-vis, FTIR, XRD, SEM, EDX and XPS analysis. AgNPs–rGO–PANI nanocomposite was loaded (0.5 mg cm⁻²) on a glassy carbon electrode (GCE) where the active surface area was maintained at 0.2 cm² for investigation of the electrochemical properties. It was found that AgNPs–rGO–PANI–GCE had high sensitivity towards the reduction of H₂O₂ than AgNPs–rGO which occurred at −0.4 V vs. SCE due to the presence of PANI (AgNPs have direct electronic interaction with N atom of the PANI backbone) which enhanced the rate of transfer of electron during the electrochemical reduction of H₂O₂. The calibration plots of H₂O₂ electrochemical detection was established in the range of 0.01 μM to 1000 μM (R² = 0.99) with a detection limit of 50 nM, the response time of about 5 s at a signal-to-noise ratio (S/N = 3). The sensitivity was calculated as 14.7 μA mM⁻¹ cm⁻² which indicated a significant potential as a non-enzymatic H₂O₂ sensor.
