ABSTRACT

Chemically modified mandua starch was successfully synthesized and applied to coat mesalamine-loaded matrix tablets. The coating material was an aqueous dispersion of mandua starch modified by sodium trimetaphosphate and sodium tripolyphosphate. To investigate the colon-targeting release competence, chemically modified mandua starch film-coated mesalamine tablets were produced using the wet granulation method followed by dip coating. The effect of the coating on the colon-targeted release of the resultant delivery system was inspected in healthy human volunteers and rabbits using roentgenography. The results show that drug release was controlled when the coating level was 10% w/w. The release percentage in the upper gastric phase (pH 1.2, simulated gastric fluid) was less than 6% and reached up to 59.51% w/w after 14 h in simulated colonic fluid. In addition to in vivo roentgenographic studies in healthy rabbits, human volunteer studies proved the colon targeting efficiency of the formulation. These results clearly demonstrated that chemically modified mandua starch has high effectiveness as a novel aqueous coating material for controlled release or colon targeting.

ABSTRACT

OBJECTIVES: Monitoring of Leishmania transmission is considered a strategic priority for sustaining elimination of visceral leishmaniasis as a public health problem in the Indian subcontinent. The objective of this study was to evaluate whether serological surveys can distinguish between communities with and without Leishmania transmission, and to assess which serological marker performs best. METHODS: Seven villages were selected from Bihar and Uttar Pradesh state, India, and categorized as either currently endemic (CE), previously endemic (PE) or nonendemic (NE). Blood samples were analyzed with the rK39 RDT, direct agglutination test (DAT), and rK39 ELISA. RESULTS: Contrary to the rK39 RDT and DAT, the rK39 ELISA showed a significant difference between all three categories of endemicity, with a seroprevalence of 5.21% in CE villages, 1.55% in PE villages, and 0.13% in NE villages. Even when only looking at the seroprevalence among children aged <10 years, the rK39 ELISA was still able to differentiate between villages with and without ongoing transmission. CONCLUSION: Our findings suggest the rK39 ELISA to be the most promising marker for monitoring of Leishmania transmission. Further validation is required, and practical, context-adapted recommendations need to be formulated in order to guide policymakers toward meaningful and sustainable surveillance strategies in the post-elimination phase.

ABSTRACT

In an area endemic with Indian visceral leishmaniasis (VL), we performed direct xenodiagnosis to evaluate the transmission of Leishmania donovani from patients with VL-human immunodeficiency virus (HIV) coinfection to the vector sandflies, Phlebotomus argentipes. Fourteen patients with confirmed VL-HIV coinfection, with a median parasitemia of 42 205 parasite genome/mL of blood, were exposed to 732 laboratory-reared pathogen-free female P argentipes sandflies on their lower arms and legs. Microscopy revealed that 16.66% (122/732) of blood-fed flies were xenodiagnosis positive. Notably, 93% (13/14) of the VL-HIV group infected the flies, as confirmed by quantitative polymerase chain reaction and/or microscopy, and were 3 times more infectious than those who had VL without HIV.

ABSTRACT

OBJECTIVE: To evaluate the utility of color Doppler ultrasonography in assessing infantile hemangioma response to treatment with oral propranolol. METHODS: A prospective study was conducted between January, 2016 and December, 2022, wherein children with symptomatic (ulceration, bleeding, pain and scarring) infantile hemangioma were given oral propranol (2 mg/kg per day in three divided doses) as outpatient therapy. The clinical response was assessed three months post-initiation of treatment (intermediate clinical response) and three months post-completion of treatment (final clinical response, FCR). The primary outcome measurement was a clinical and radiological response (resistivity index (RI), pulsatility index (PI) and peak systolic velocity) to treatment. The secondary outcomes assessed were the complications related to treatment. RESULTS: Out of 601 patients who were started on propranolol, 99 developed severe adverse effects and were excluded from analysis. At FCR assessment, out of 502 participants, 64.3% (n = 323) showed excellent response, 17.7% (n = 89) showed partial, and 17.9% (n = 90) were non-responders. A significant increase in RI and PI values was noted in all children following propranolol treatment for six months. An increase > 7.5% in RI could identify responders with 92% sensitivity, 91% specificity and area under the curve (AUC) of 0.963. An increase of > 11.5% in PI could identify responders with 86% sensitivity, 91% specificity and AUC of 0.896. Patients initially showing no response but later becoming excellent responders had significantly higher RI and PI values. CONCLUSIONS: Color Doppler ultrasonography is a valuable tool in predicting the treatment outcome of infantile hemangioma using propranolol.

ABSTRACT

Objectives: To investigate the efficacy and safety of individualized homeopathic medicines (IHMs) in treating hemorrhoids compared with placebo. Design: This is a double-blind, randomized (1:1), two parallel arms, placebo-controlled trial. Setting: The trial was conducted at the surgery outpatient department of the State National Homoeopathic Medical College and Hospital, Lucknow, Uttar Pradesh, India. Subjects: Patients were 140 women and men, aged between 18 and 65 years, with a diagnosis of primary hemorrhoids grades I-III for at least 3 months. Excluded were the patients with grade IV hemorrhoids, anal fissure, and fistula, hypertrophic anal papillae, inflammatory bowel disease, coagulation disorders, rectal malignancies, obstructed portal circulation, patients requiring immediate surgical intervention, and vulnerable samples. Interventions: Patients were randomized to Group 1 (n = 70; IHMs plus concomitant care; verum) and Group 2 (n = 70; placebos plus concomitant care; control). Outcome measures: Primary-the anorectal symptom severity and quality-of-life (ARSSQoL) questionnaire, and secondary-the EuroQol 5-dimensions 5-levels (EQ-5D-5L) questionnaire and EQ visual analogue scale (VAS); all of them were measured at baseline, and every month, up to 3 months. Results: Out of the 140 randomized patients, 122 were protocol compliant. Intention-to-treat sample (n = 140) was analyzed. The level of significance was set at p < 0.05 two tailed. Statistically significant between-group differences were elicited in the ARSSQoL total (Mann-Whitney U [MWU]: 1227.0, p < 0.001) and EQ-5D-5L VAS (MWU: 1228.0, p = 0.001) favoring homeopathy against placebos. Sulfur was the most frequently prescribed medicine. No harm or serious adverse events were reported from either of the groups. Conclusions: IHMs demonstrated superior results over placebo in the short-term treatment of hemorrhoids of grades I-III. The findings are promising, but need to be substantiated by further phase 3 trials. Clinical Trial Registration Number: CTRI/2020/03/024342.

ABSTRACT

Background: Patients' satisfaction with healthcare services contributes to their compliance with the treatment and thus impacts their health. Therefore, patient satisfaction is increasingly being used as an indicator of health system performance in a country. Though several studies have been reported from different parts of India, most did not include psychiatric patients. This study assessed the level of satisfaction of psychiatric outpatients and its association with socio-demographic, hospital-related, and treatment-related variables. Methods: This cross-sectional study assessed 152 patients attending psychiatry outpatient department (OPD) of a tertiary care hospital. Treatment-related satisfaction was measured using the Short Assessment of Patient Satisfaction (SAPS) scale, and variables not related to treatment were assessed using Likert scales. Results: Most participants were satisfied with the overall cleanliness of the hospital (82.9%), the useable condition of toilets (73%), and waiting time in the OPD ticket counter, doctor's room, and pharmacy. More than 80% were pleased with the OPD staff's behavior and working efficiency. In the seven dimensions of the SAPS scale, satisfaction level was variable. Overall satisfaction with the care received in the hospital was 60.5%. Conclusions: The level of patient satisfaction is good in psychiatry OPD services of our hospital, and it depends on treatment-independent variables also. So, liaison between the medical- and non-medical-management teams is crucial to augment patient satisfaction.
