ABSTRACT

Background: The Corona Virus Disease-19 (COVID-19) has been declared a pandemic by the World Health Organization (WHO). We state the consolidated and systematic approach for academic medical centres in response to the evolving pandemic outbreaks for sustaining medical education.Discussion: Academic medical centres need to establish a 'COVID-19 response team' in order to make time-sensitive decisions while managing pandemic threats. Major themes of medical education management include leveraging on remote or decentralised modes of medical education delivery, maintaining the integrity of formative and summative assessments while restructuring patient-contact components, and developing action plans for maintenance of essential activities based on pandemic risk alert levels. These core principles must be applied seamlessly across the various fraternities of academic centres: undergraduate education, residency training, continuous professional development and research. Key decisions from the pandemic response teams that help to minimise major disruptions in medical education and to control disease transmissions include: minimising inter-cluster cross contaminations and plans for segregation within and among cohorts; reshuffling academic calendars; postponing or restructuring assessments.Conclusions: While minimising the transmission of the pandemic outbreak within the healthcare establishments is paramount, medical education and research activities cannot come to a standstill each time there is a threat of one.

ABSTRACT

The neuro-anatomical sites and molecular mechanism of action of gabapentin (GBP)-morphine interaction to prevent and reverse morphine side effects as well as enhancement of the analgesic effect of morphine is not known. Therefore, we examined the combined effects of GBP-Morphine on acute morphine induced c-Fos expression in rat striatum. The combined effect of GBP-Morphine was examined by means of c-Fos immunohistochemistry. A single intraperitoneal injection (i.p.) of morphine (10 mg/kg), saline (control), co-injection of GBP (150 mg/kg) with morphine (10 mg/kg) was administered under anaesthesia. Ninety minutes after drugs administration the deeply anesthetized rats were perfused transcardially with 4% paraformaldehyde. Serial 40 mum thick sections of brain were cut and processed by immunohistochemistry to locate and quantify the sites and number of neurons with c-Fos immunoreactivity. Detection of c-Fos protein was performed using the peroxidase-antiperoxidase (PAP) detection protocol. Our present study demonstrated that, administration of GBP (150 mg/kg, i.p.) in combination with morphine (10 mg/kg, i.p.) significantly (p < 0.01) attenuated the acute morphine (10 mg/kg, i.p.) induced c-Fos expression in the rat striatum. Present results showed that GBP-morphine combination action prevented the acute morphine induced c-Fos expression in rat striatum. Moreover, this study provides first evidence of neuro-anatomical site and that GBP neutralized the morphine induced activation of rat striatum.

ABSTRACT

Gabapentin (neurontin), a GABA analogue anticonvulsant has proven to be effective in anti-nociceptive activity as well as for the treatment of anxiety. Gabapentin (GBP) is well tolerated and shows very favorable side effects profile: The exact molecular mechanism of action of GBP to block postoperative pain and stress is not known. Therefore, to identify the functional neuroanatomical target sites of GBP in post-surgery as well as its effect on postsurgical process, we examined the effects of GBP on c-Fos expression in the supraspinal part of the central nervous system in rats. Using a well-validated rat model of surgical pain, we studied the neuroanatomical functional target sites of gabapentin after paw surgery. The effect of GBP was examined by means of c-Fos immunohistochemistry. A single intraperitoneal injection (i.p.) of GBP (150 mg/kg) or saline (control) was administered 20 min before surgical incision in the paw under anesthesia. Ninety minutes after surgical incision, the deeply anesthetized rats were perfused transcardially with 4% paraformaldehyde. Serial 40-microm-thick sections of whole brain (except spinal cord) were cut and processed by immunohistochemistry to locate and quantify the sites and number of neurons with c-Fos immunoreactivity. Detection of c-Fos protein was performed using the peroxidase-antiperoxidase detection protocol. Our present study demonstrated that compared to control, administration of GBP (150 mg/kg, i.p.) before paw surgery significantly (p < 0.01) attenuated the incision-induced c-Fos expression only in the paraventricular nucleus of the hypothalamus. In addition, GBP-induced increase in c-Fos expression was observed in the dorsal raphe (DRN) and in the nucleus raphe magnus. Present results indicate that GBP may differentially modulate c-Fos expression in surgical paw incision. Moreover, this study provides some clue to examine whether GBP exerts its action simultaneously through two separate pathways in post-surgery.
