The Development of School Based Curriculum in Ghana Schools: The Effects on Students

The concept of school based curriculum development has been of keen interest through my profession as a teacher. Since end of school test is based on the central curriculum, teachers and stakeholders usually pay less attention to other curriculum types, like school-based curriculum development (SBCD). Can students achieve something out of SBCD? Does it have any positive effect on students learning? With different learning needs of learners and dynamism in education. I argue that SBCD should be introduced in Ghana schools. Through literature mining, mine and colleague’s experience, I discuss the following as to why SCBD should be introduced into Ghana schools: First to meet the needs and interests of students and the school community; Second, to insert school learning into local contexts, knowledge, and resources, and meet local and national aspirations; Thirdly, respond to new social issues and technology in education. Keywords: School based curriculum development (SBCD), central curriculum, student learning, Student interest, community interest, social issues, local learning context.

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Inhibition of prostaglandin synthesis does not alter the decrease in pre-capillary resistance in the human calf in response to small cumulative increases in venous congestion

Metadata onlyThe decrease in pre-capillary resistance in the human calf during gradual cumulative increases in venous congestion pressure has been proposed to represent vasodilator signalling between the venous and arterial microcirculations. The present study investigated whether prostaglandins are involved in this local flow regulation by measuring calf blood flow and microvascular filtration capacity using strain gauge plethysmography in young male subjects before (baseline) and after taking either ibuprofen, an inhibitor of prostaglandin synthesis (1600 mg over 2 days), or placebo. At baseline, inflation of a thigh cuff to 50 mmHg in steps of 10 mmHg, each held for 5 min, did not decrease arterial inflow, confirming a reduction of pre-capillary resistance. Ibuprofen reduced resting calf blood flow by 35% (P<0.001), but flow at a Pcuff (cuff pressure) of 50 mmHg was 97% of this value, i.e. pre-capillary resistance had decreased to the same extent as before inhibition of prostaglandin synthesis. Ibuprofen also reduced microvascular filtration capacity (2.98±1.20 compared with 3.71±0.89 ml·min-1·100 ml-1·mmHg-1×10-3; P<0.05), probably due to a combination of reduced arterial inflow and lower venous pressure (8.5±5.2 compared with 12.6±2.8 mmHg; P<0.05) that moderated capillary hydrostatic pressure to override direct effects of inhibition of prostaglandin synthesis on permeability. Placebo was without effect on any measurement. It is unlikely therefore that prostaglandin-mediated vasodilator signals, which have been demonstrated between paired veins and arteries, are important in local vasodilation in response to venous congestion
