Assessment of lifestyle changes in combating the COVID-19 pandemic among people of Karachi, Pakistan.

COVID-19 arose as a pandemic that wreaked havoc all over the world. Study determines lifestyle changes adopted by people of Karachi in response to COVID-19 pandemic. This was the cross-sectional study and carried out at public sector hospital and 218 participants were selected through random sampling method.

Assessment of Patient Safety in a Low-Resource Health Care System: Proposal for a Multimethod Study.

Background: The high prevalence of adverse events (AEs) globally in health care delivery has led to the establishment of many guidelines to enhance patient safety. However, patient safety is a relatively nascent concept in low- and middle-income countries (LMICs) where health systems are already overburdened and underresourced. This is why it is imperative to study the nuances of patient safety from a local perspective to advocate for the judicious use of scarce public health resources.

Insight into Private General Physicians' Practices: an Exploratory Qualitative Study in a Rural District of Pakistan.

Objective: The study aimed to assess private general physicians'(GPs) healthcare practices, identifying perceived malpractices, the support they receive, and barriers they experience in providing healthcare services.

Design: Qualitative exploratory study.

Setting: Rural district, Thatta in Province of Sindh, Pakistan.

Multi-Segment Leads To Reduce RF Heating in MRI: A Computational Evaluation at 1.5T and 3T.

Implanted neurostimulators are currently in widespread use and allow patients to receive therapeutic nerve stimulation for a variety of conditions. Such devices often make use of long leads extending from the device to the relevant nerve to deliver their stimulation. These leads carry a significant radiofrequency (RF) safety concern for patients who also receive magnetic resonance imaging (MRI) scans.

Effect of direct voltage induction by low-frequency security systems on neurostimulator lead.

Low-frequency (LF) security systems, such as antitheft electronic article surveillance (EAS) gates emit strong magnetic fields that could potentially interfere with neurostimulator operation. Some patients reported pain and shocking sensations near EAS gates, even after they turned off their pulse generator. To investigate the direct voltage induction of EAS systems on neurostimulator leads, we evaluated voltages induced by two EAS systems (14 kHz continuous wave or 58 kHz pulsed) on a 40 cm sacral neurostimulator lead formed in a circular loop attached to a pulse generator that was turned off.
