Rotavirus-associated acute diarrhea outbreak in West Shewa Zone of Oromia Regional State, Ethiopia, 2017

Incidence and predictors of postoperative severe acute pain within 24 hours after cesarean section performed under spinal anesthesia at public hospitals in West Shoa, Ethiopia, 2022 prospective cohort study

Background

Acute postoperative pain is common after a caesarean section; the mother suffers severe pain in the first 24 h after the caesarean section compared to spontaneous birth. Failure to discover predictors of pain leads to maternal dissatisfaction, increased expenses, and restricted movement; it increases the risk of deep vein thrombosis, lengthens hospital stays, and decreases social intimacy.

Methods and materials

An institution-based prospective cohort study was conducted among 422 women who went to undergo caesarean sections under spinal anaesthesia at public hospitals in West Shoa from 30 July to 30 October. Participants were selected by systematic random sampling. Data were collected by a structured questionnaire, and the collected data were entered into SPSS version 20 and exported into STATA 64 for analysis. The results were presented in tables and figures. Risk factors were assessed by Poisson regression with a robust standard error.

Results

The overall incidence of severe postoperative pain after a caesarean section performed under spinal anaesthesia within 24 h of follow-up was 50.4% [95% confidence interval (CI): 40.7, 60.1]. Preoperative anxiety risk ratio 1.7 (95% CI: 1.4-2.0), preoperative pain risk ratio 1.3 (95% CI: 1.0-1.48), type of incision risk ratio 11.3 (95% CI: 1.1-1.6), spinal anaesthesia without adjuvants risk ratio 4.1 (95% CI: 1.5-10.9), and duration of surgery risk ratio 1.5 (95% CI: 1.3-1.8) were found to be predictors for postoperative severe acute pain after caesarean section performed under spinal anaesthesia.

Conclusion

In this study, the overall incidence of severe acute pain after a caesarean section under spinal anaesthesia was high. Preoperative fear, duration of the operation, preparatory pain, spinal anaesthesia without the use of adjuvants, and the type of incision were risk factors for severe acute postoperative pain after a caesarean section under spinal anaesthesia.

Prospecting Human Milk Oligosaccharides as a Defense Against Viral Infections

In addition to providing maximal nutritional value for neonatal growth and development, human milk functions as an early defense mechanism against invading pathogens. Human milk oligosaccharides (HMOs), which are abundant in human milk, are a diverse group of heterogeneous carbohydrates with wide ranging protective effects. In addition to promoting the colonization of beneficial intestinal flora, HMOs serve as decoy receptors, effectively blocking the attachment of pathogenic bacteria. HMOs also function as bacteriostatic agents, inhibiting the growth of gram-positive bacteria. Based on this precedence, an emerging area in the field has focused on characterizing the antiviral properties of HMOs. Indeed, HMOs have been evaluated as antiviral agents, with many possessing activity against life-threatening infections. This targeted review provides insight into the known glycan-binding interactions between select HMOs and influenza, rotavirus, respiratory syncytial virus, human immunodeficiency virus, and norovirus. Additionally, we review the role of HMOs in preventing necrotizing enterocolitis, an intestinal disease linked to viral infections. We close with a discussion of what is known broadly regarding human milk oligosaccharides and their interactions with coronaviruses.
