In vitro and in vivo anthelmintic response of the seeds of Amomum subulatum roxb and Vitex negundo.

The current study was designed to check the anthelmintic activities of some local plants. Seeds of Amomum (A.) subulatum and Vitex (V.) negundo in different solvents were subjected to in vitro (adult motility assay; AMA and egg hatch assay; EHA) and in vivo (faecal egg count reduction test; FECRT) anthelmintic activity testing protocols using Haemonchus (H.) contortus as an experimental model. The results of AMA, EHA, and FECRT were statistically analysed through linear regression and Duncan multiple range test. In AMA test, at 50 mg mL-1 concentration, the percent mortality of H. contortus was higher in A. subulatum than V. negundo, whereas, in EHA test, A. subulatum was proven better ovicidal (LC50=14.2 µg mL-1) than V. negundo (LC50= 65.7405 µg mL-1). The FECRT also indicated the better efficacy of A. subulatum than V. negundo against natural infection of gastrointestinal (GI) parasites. The crude powder of plants used in this study showed 29.6% to 57.7% anthelmintic. The reduction rate was found higher for A. subulatum (3 g kg-1) as compared to V. negundo (7 g kg-1). Reagrding efficacy analysis of solvents used for plants extract, ethyl acetate and chloroform were found better in increasing ovicidal activity in adult worms (in vitro testing), whereas, the crude aqueous methanol was found better than the crude powders in in vivo testing. It will be beneficial to document the indigenous knowledge to standard scientific procedures for their validation. This study will help to motivate the farmers to make a better choice of cultivation of the indigenous plants because of their varying efficacies as an alternative preventive approach against the GI parasitic infections.

A novel treatment of bromelain and acetylcysteine (BromAc) in patients with peritoneal mucinous tumours: A phase I first in man study.

BACKGROUND: Bromelain (Brom) and Acetylcysteine (Ac) have synergistic activity resulting in dissolution of tumour-produced mucin both in vitro and in vivo. The aim of this study was to determine whether treatment of mucinous peritoneal tumour with BromAc can be performed with an acceptable safety profile and to conduct a preliminary assessment of efficacy in a clinical setting. METHODS: Under radiological guidance, a drain was inserted into the tumour mass or intraperitoneally. Each patient could have more than one tumour site treated. Brom 20-60 mg and Ac 1·5-2 g was administered in 5% glucose. At 24 h, the patient was assessed for symptoms including treatment-related adverse events (AEs) and the drain was aspirated. The volume of tumour removed was measured. A repeat dose via the drain was given in most patients. All patients that received at least one dose of BromAc were included in the safety and response analysis. FINDINGS: Between March 2018 and July 2019, 20 patients with mucinous tumours were treated with BromAc. Seventeen (85%) of patients had at least one treatment-emergent AE. The most frequent treatment-related AEs were CRP rise (n = 16, 80%), WCC rise (n = 11, 55%), fever (n = 7, 35%, grade I) and pain (n = 6, 30%, grade II/III). Serious treatment-related AEs accounted for 12·5% of all AEs. There were no anaphylactic reactions. There were no deaths due to treatment-related AEs. An objective response to treatment was seen in 73·2% of treated sites. CONCLUSION: Based on these preliminary results and our preclinical data, injection of BromAc into mucinous tumours had a manageable safety profile. Considerable mucolytic activity was seen by volume of mucin extracted and radiological appearance. These results support further investigation of BromAC for patients with inoperable mucinous tumours and may provide a new and minimally invasive treatment for these patients.

Prevalence and molecular detection of contagious bovine pleuropneumonia in large ruminants in Punjab, Pakistan.

Contagious bovine pleuropneumonia (CBPP) is a highly contagious disease of cattle caused by Mycoplasma mycoides subsp. mycoides. It is characterized by anorexia, fever, dyspnea, polypnea, cough, and nasal discharges. Gross lesions in the lung such as marbling, sequestra, thickening of interlobular septa, and consolidation are evident. Serological tests including complement fixation test and competitive enzyme-linked immunosorbent assay and molecular tests such as polymerase chain reactions are used for diagnostic purposes. In this study, lung samples of suspected large ruminants (cattle n=560, buffalo n=293) were collected from abattoirs of three districts of Punjab namely Lahore, Kasur and Jhang. PCR was performed with specific primers, targeting the 16S ribosomal RNA gene to detect the positive cases. The results indicated that 49 samples (8.75%) of cattle were positive, with maximum prevalence was observed in Jhang with 16 positive samples (10.06%), but CBPP was not detected in any buffalo sample. High prevalence of disease was seen in cattle of more than seven years of age, in female cattle, and in cross-bred cattle. Age and gender were found significantly associated (P<0.05) with the prevalence of the disease. Gene sequencing of identified 5 isolates of Mycoplasma mycoides subsp. mycoides had more than 99% similarities with the strains isolated from China, Italy, Australia and Tanzania and were categorized into a monophyletic group but strain isolated from Portugal had more than 55% variable regions, hence clustered separately. This study confirms the presence of contagious bovine pleuropneumonia in the country which can be a threat to the livestock export market and warrants the implementation of control measures to mitigate the economic losses associated with the disease.

Frequency and associated factors for anxiety and depression in pregnant women: a hospital-based cross-sectional study.

Antepartum anxiety and/or depression is a major public health problem globally. The aim of this study was to estimate the frequency of antepartum anxiety and/or depression among pregnant women. This was a cross-sectional study conducted in a tertiary care hospital among pregnant women. A total of 165 pregnant women were interviewed by a clinical psychologist using HADS for assessing anxiety and/or depression and also collected information regarding sociodemographic, obstetric, family relationships, and home environment. Out of the total of 165 pregnant women about 70 percent of them were either anxious and/or depressed. The increasing age of women (P-value = 0.073), not having any live birth (P-value = 0.036), adverse pregnancy outcome in past including death of a child, stillbirth or abortion (P-value = 0.013), participant's role in household decision making (P-value = 0.013), and domestic violence (verbal or physical abuse towards mother or children by any family member) (P-value = 0.123). Our study highlights that anxiety and/or depression is quite common among pregnant women. Therefore, there is a need to incorporate screening for anxiety and depression in the existing antenatal programs and development of strategies to provide practical support to those identified.

Effectiveness of counseling for anxiety and depression in mothers of children ages 0-30 months by community workers in Karachi, Pakistan: a quasi experimental study.

BACKGROUND: The prevalence of anxiety/depression is quite high during the perinatal period but unfortunately its detection and treatment have been less than satisfactory. Moreover, many women are reluctant to take pharmacotherapy for fear of excretion of drugs into their breast milk. This study assesses the effectiveness of counseling from minimally trained community health workers in reducing anxiety/depression, the rate of recurrence and the interval preceding recurrence in women during first two and a half years after childbirth. METHODS: In a quasi-experimental study, community women from two under-privileged communities were trained in data gathering, teaching healthy child-rearing practices, basic counseling skills, and screening for anxiety/depression by using an indigenously developed questionnaire, the Aga Khan University Anxiety and Depression Scale (AKUADS). The diagnosis was further confirmed by a clinical psychologist using DSM IV criteria. After obtaining consent, 420 women were screened and 102 were identified as having anxiety/depression. Screening was carried out after 1, 2, 6, 12, 18, 24 and 30 months of a live birth. Only 62 out of 102 agreed to be counseled and received eight weekly sessions. AKUADS was re-administered at 4 weeks and 8 weeks after the beginning of counseling; this was followed by the clinical psychologist's interview for confirmation of response. After recovery, screening was continued every 3 months for detection of recurrence throughout the study period. Out of the women who had declined counseling 12 agreed to retake AKUADS after 4 and 8 weeks of diagnosis. Independent samples t-test, chi-square test, Repeated Measures ANOVA and Kaplan Meier technique were used for the analysis. RESULTS: A significant decline in level of anxiety/depression was found in both the counseled and the non-counseled groups at 4 and 8 weeks (p-value < 0.001) but the counseled group fared better than the non-counseled for recovery, reduction in the rate of recurrence and increase in the duration before relapse. CONCLUSIONS: As our results cannot be generalized; further studies need to be carried out, to assess the benefit of incorporating minimal counseling skills in the training of community health workers.

Association of various reproductive rights, domestic violence and marital rape with depression among Pakistani women.

BACKGROUND: Depression among women is common in developing countries. Gender inequality can contribute to women's risk for depression. Lack of reproductive and sexual rights is an important marker of gender inequality and women do not have the freedom to express their reproductive and sexual needs in many parts of the world. Therefore we designed this study to determine the association of depression with lack of various reproductive rights and domestic violence among married women in Karachi, Pakistan. METHODS: A case-control study with 152 cases and 152 controls, which included women 15-48 years, recruited from two teaching hospitals from 1st June 2007 through 31st August 2007. The SRQ was administered to all subjects. A cut off score of 8 was used to confirm cases of depression diagnosed by physicians, and to exclude cases of depression from the controls. Self-administered questionnaire was used to assess the risk factors. RESULTS: 61% of the cases and 43% of the controls were ever abused by spouse and the frequency of marital rape was 33% in cases and 13% in controls. After adjusting for the effects of other variables in the model, less than 18 years of age at marriage (OR 2.00; 95% CI = 1.07, 3.7), decision for marriage by parents (OR 3.51; 95% CI = 1.67, 7.37), abuse by in laws (OR 4.91; 95% CI = 2.66, 9.06),

Post partum anxiety and depression in peri-urban communities of Karachi, Pakistan: a quasi-experimental study.

BACKGROUND: Postpartum anxiety and depression is a major public health concern because of its adverse effects on the cognitive and social development of the infant. Globally postpartum depression has been widely investigated but as anxiety is a more prominent feature of postpartum depression we assessed the prevalence of anxiety and depression and their associated factors in post partum women. METHODS: A quasi-experimental study investigating the impact of postpartum anxiety and depression on child growth and development was conducted in two peri-urban, multiethnic, communities of Karachi, a mega city of Pakistan. A house to house questionnaire based survey was done by trained field workers; 420 consenting pregnant women were identified and data for socio-demographic, home environment and family relationship variables was collected between 36 weeks of pregnancy and within 10 days of childbirth. Mother's levels of anxiety and depression were assessed after one month, two months, six months and twelve months of childbirth; this was two step process: initially an indigenous, validated screening instrument Aga Khan University Anxiety and Depression Scale was used and diagnostic confirmation was done through a psychologist's interview based on DSM IV criteria. Women found to be anxious and depressed at least once out of four assessments were considered for the computation of overall prevalence of postpartum anxiety and depression as well as its risk factors. However, point prevalence's of postpartum anxiety and depression were also reported at each assessment time. Two sixty seven women could be followed for one year. Data was analyzed using SPSS. Chi-square test, simple and multiple logistic regression were used to see the association of different factors. RESULTS: The overall prevalence of postpartum anxiety and depression was found to be 28.8 percent. Domestic violence, difficulty in breast feeding at birth and unplanned current pregnancy were found to be significantly associated with postpartum anxiety and depression. CONCLUSION: Domestic violence and not having the right to plan pregnancy are related to the patriarchal culture and lack of empowerment of women. The association with difficulties in breast feeding needs to be further explored in future studies.

Massive retroperitoneal pseudotumour in a patient with type 3 von Willebrand disease.

Formation of destructive haemorrhagic pseudocysts or pseudotumours thought to arise from unresolved, encapsulated haematomas is a well-recognized, rare complication of severe haemophilia A or B, and has been reported in a single patient with von Willebrand disease (vWD). We report a 41-year-old patient with type 3 vWD who underwent incomplete resection of a large retroperitoneal pseudocyst in 1995 and presented with a recurrent, extensive right abdominal and flank mass and signs and symptoms of large bowel obstruction. He required emergency partial colectomy for bowel ischaemia and removal of his right kidney, which was hydronephrotic due to prolonged ureteral obstruction by the pseudocyst. Following repeat partial resection of the pseudotumour, he developed persistent bleeding into the operative site despite aggressive administration of von Willebrand factor (vWF)-rich factor VIII concentrates, resulting in retroperitoneal haematomas and abscesses, which resolved after 13 months of percutaneous drainage, extended supplementation of vWF and antibiotic therapy.

Mechanisms of Ca2+ antagonism in imipramine-induced toxicity of isolated adult rat cardiomyocytes.

Classic explanations of cyclic antidepressant toxicity often focus on Na+ channel blockade; however, cyclic antidepressant toxicity often causes decreased myocardial contractile function. The present experiments first examine inhibition of cytosolic Ca2+ signals by imipramine. Second, the experiments test if alkalinization prevents the inhibition of Ca2+ signals. Cardiomyocytes from adult rat hearts were loaded with fura-2 dye, and intracellular calcium, [Ca2+]i, was quantified using ratio fluorescence techniques. Changes in [Ca2+]I were induced by electrical pacing, depolarization with KCl (84 mM), or treatment with caffeine (10 mM). Imipramine (10-30 microM) inhibited [Ca2+]i transients in electrically paced cardiomyocytes. Imipramine (7.5-30 microM) also inhibited Ca2+ signals in KCl depolarized cells. These inhibitory effects were similar to those observed with nisoldipine (100-2000 nM), a selective L-channel blocker. The rise in [Ca2+]i that was triggered with caffeine (10 mM) was not significantly changed by imipramine (30 microM). Inhibition of KCl-induced Ca2+ signals by imipramine was prevented by alkalinization of the medium (tris(hydroxymethyl)aminomethane, pH 7.6), but not by elevation of extracellular sodium to 170 mM. Alkalinization was effective in the presence of HOE642, a selective Na+/H+ (NHE) subtype 1 inhibitor. These data show that imipramine causes Ca2+ antagonism in heart cells which is independent of sarcoplasmic reticulum Ca2+, and that alkaline treatment prevents this Ca2+ antagonism rather than stimulating an alternate source of Ca2+ via Na+/H+ and subsequent Na+/Ca2+ exchange.
