Exploring Patient Safety Culture: A Study of Community Pharmacies in Karachi, Pakistan.

Background Community pharmacies are integral to the healthcare system, actively contributing to patient safety through accurate dispensing, education, collaboration, monitoring, and the implementation of safety protocols. Their accessibility and role as medication experts make them key partners in promoting positive health outcomes for individuals and communities. Objective The current study will evaluate the patient safety culture (PSC) among community pharmacies in Karachi, Pakistan. Additionally, this study will measure the association between patient safety culture in community pharmacies and the demographic characteristics of the pharmacy staff. Methods A cross-sectional survey of pharmacy staff was conducted using a survey instrument developed by the US Agency for Healthcare Research and Quality (AHRQ). Demographic variables and assessments of safety culture in pharmacies were studied. The data were analyzed using descriptive statistics. Results Among the 102 participants, positive responses ranged from 30% to 87.5%. The highest positive response was for the dimension "mistakes in communication" (86.3%), followed by "communication across shifts" (82.2%) and "communication openness" (81.7%). The dimensions "overall perceptions of patient safety" and "response to mistakes" had the lowest positive responses (56.0% and 60.9%, respectively). Furthermore, many staff did not regularly record the errors, even if they impacted the practices. Conclusion There was an overall unfavorable perception of patient safety culture among the surveyed pharmacies of Karachi, Pakistan. However, the communication dimensions showed the highest positive response. There is a strong need to improve the overall perception of patient safety among the staff and develop an optimistic response to mistakes.

Hughes-Stovin Syndrome: A Case Report on a Rare, Life-Threatening Vasculitis.

Hughes-Stovin Syndrome (HSS) is a rare vasculitic disorder characterised by widespread pulmonary artery aneurysms. It shares some features with Behçet disease. Currently, the diagnosis is based on clinical suspicion. Our case describes a young male who presented with haemoptysis and previous history of pulmonary embolism. Workup was essentially unremarkable, but imaging revealed multiple pulmonary artery aneurysms. Timely initiation of glucocorticoids and immunosuppression with cyclophosphamide led to improvement. High-dose glucocorticoids and immunosuppressants are the mainstays of treatment. Untreated cases can result in fatal outcomes.

Neuroprotective potential of polydatin against motor abnormalities and dopaminergic neuronal loss in rotenone induced Parkinson model / Potencial neuroprotector de la polidatina contra las anomalías motoras y la pérdida neuronal dopaminérgica en un modelo de Parkinson inducido por la rotenona

Among the neurodegenerative disorders, Parkinson disease (PD) is ranked as second most common. The pathological hallmark is selective degeneration of the dopaminergic neurons in the nigro-striatal regions of brain with appearance of the Lewy bodies. Present study explores the neuro-protective potential of polydatin in terms of amelioration of degeneration of dopaminergic neurons in nigro-striatal regions of brain and distorted neuromotor behavior in the rotenone model of Parkinson's disease. Thirty-six male Sprague Dawley rats were divided into three groups. Group A (control), Group B (rotenone treated) and Group C (rotenone+polydatin treated). Rotenone was administrated intraperitoneally (i.p) at a dose of 3 mg/kg/body weight while polydatin was given i.p. at a dose of 50 mg/ kg/body weight for four weeks. Then, animals were sacrificed; substantia nigra (SN) & striatum isolated from brain and five micron thick sections were prepared. Cresyl violet (CV), H&E and Immuno-histochemical staining using anti-TH antibody was done. Motor behavior was assessed weekly throughout the experiment using five different methods. Rotenone treated parkinsonian animals showed deterioration of motor behavior, weight loss, loss of dopaminergic neurons and diminished immune-reactivity in the sections from the nigrostriatal regions of these animals Polydatin+rotenone treatment showed contradicting effects to parkinsonism, with amelioration in weight loss, neuro-motor behavior, dopaminergic loss and immune-reactivity against dopaminergic neurons. Present study revealed a neuro-protective potential of polydatin in animal model of PD by ameliorating the neuro-motor abnormalities and degeneration of dopaminergic neurons in nigrostriatal regions.

Entre los trastornos neurodegenerativos, la enfermedad de Parkinson (EP) se clasifica como la segunda más común. El sello patológico es la degeneración selectiva de las neuronas dopaminérgicas en las regiones nigro-estriatales del cerebro, con la aparición de los cuerpos de Lewy. El presente estudio explora el potencial de protección neuronal de la polidatina en términos de la mejora de la degeneración de las neuronas dopaminérgicas en las regiones nigro-estriatales del cerebro y el comportamiento neuromotor distorsionado en el modelo de rotenona de la enfermedad de Parkinson. Treinta y seis ratas macho Sprague Dawley se dividieron en tres grupos: Grupo A (control), Grupo B (tratado con rotenona) y Grupo C (tratamiento con rotenona + polidatina). La rotenona se administró por vía intraperitoneal (i.p.) a una dosis de 3 mg/kg/peso corporal, mientras que la polidatina se administró i.p. a una dosis de 50 mg/kg/ peso corporal durante cuatro semanas. Posteriormente, los animales fueron sacrificados. Se aislaron la substantia nigra (SN) y cuerpo estriado de los cerebros y se realizaron secciones de cinco micras de espesor. Se realizó una tinción de violeta de cresilo (CV), H&E y tinción inmunohistoquímica usando anticuerpo anti-TH. El comportamiento motriz se evaluó semanalmente durante todo el experimento utilizando cinco métodos diferentes. Los animales parkinsonianos tratados con rotenona mostraron deterioro del comportamiento motriz, pérdida de peso, pérdida de neuronas dopaminérgicas y disminución de la reactividad inmune en las secciones de las regiones nigroestriadas. El tratamiento con polidatina + rotenona mostró efectos contrarios al parkinsonismo, con mejoría en la pérdida de peso, en el comportamiento motor, en la pérdida dopaminérgica y en la reactividad inmune contra las neuronas dopaminérgicas. El presente estudio reveló un potencial de protección neuronal de la polidatina en el modelo animal de la EP al mejorar las anomalías neuro-motoras y la degeneración de las neuronas dopaminérgicas en las regiones nigroestriatales.

Efeitos do óleo de Nim (Neem) na estrutura e função de ovários de ratas albinas adultas / Effect of Neem oil on the structure and function of the mature female albino rat ovaries

Objetivo: Esse estudo foi realizado para observar o efeito do tratamento com óleo de Nim sobre a fertilidade, a estrutura microscópica do ovário e as alterações associadas ao nível sérico dos hormônios reprodutivos em ratas albinas adultas. Métodos: Os animais foram divididos em grupos – Grupo A1: fêmeas tratadas com baixa dose (0,6 ml de óleo de Nim/animal); Grupo A2: fêmeas tratadas com alta dose (1,2 ml de óleo de Nim/animal); Grupo A3: controles para Grupo A1, receberam dose equivalente de óleo de amendoim; Grupo A4: controles para Grupo A2, receberam dose equivalente de óleo de amendoim. Os animais foram observados por seis semanas. No fim desse período, os animais foram anestesiados, o sangue coletado por punção cardíaca e, depois, sacrificados. Os ovários foram removidos e fixados em solução de formol a 10% para microscopia e em metanol, para cromatografia líquida de alto desempenho. Rresultados: À microscopia, os cortes dos ovários revelaram diminuição do número de folículos maduros. Alterações significativas nos níveis de hormônios reprodutivos e a presença de concentrações maiores dos componentes ativos do óleo de Nim nas gônadas entre as ratas tratadas, também foram demonstradas neste estudo. Cconclusões: Esses achados permitem concluir que o óleo de Nim tem potencial anticonceptivo dose-dependente em ratas albinas.
