The impact of childhood food allergy on quality of life of the paediatric population in Jeddah, Saudi Arabia

BackgroundFood allergy is an allergic reaction to any type of food that differs in its severity and impact on the patient's life as well as on caregivers. AimsTo measure the quality of life in the paediatric population with food allergy at National Gourd Health Affairs Jeddah, Saudi Arabia.Methods The food allergy quality of life-parent form was used in this study. The sample size is 75 participants. An Arabic translated and validated version of both questionnaires, with minor modifications were used. Demographic profile, allergy profile, and symptoms profiles were described as frequencies. Cronbach’s alpha was calculated for each food allergy quality of life domain. Food allergy quality of life domains were described using the average scores of the summed corresponding variables. A two-way MANOVA was carried out.Results The total score for patients aged 0–3, 4–6, and 7–12 are 2.01, 2.56, 2.33, respectively. There was no significant interaction between the independent variables (p=0.123). Age group and gender had no effect on the combined score measuring the quality of life (p=0.061, and 0.465, respectively). The total score for parental concern about food safety is 3.56±1.15 (SD) and the total score for child's concern about food safety is 2.81±1.45 (SD). Total score for these domains general health perceptions, parental emotional impact, general mental health, and family and child's activities are 1.6±0.79, 2.84±1.36, 3.09±1.28, 2.39±1.27, respectively.ConclusionThere were no significant differences between age groups or gender in the overall score. Only minimal differences were observed in (emotional, social and dietary limitation). We highly recommend further studies in the same field to be able to generalize the results in the Saudi paediatric population

Antimicrobial effect of different types of honey on Staphylococcus aureus

Honey exhibits antimicrobial activities against a wide range of bacteria in different milieu. This study aims to compare the effects of five types of honey (both imported and local Saudi honey) against Staphylococcus aureus. The five types of honey (Manuka Honey UMF +20, Manuka Honey UMF +16, Active +10 Manuka Honey, Sidr honey and Nigella sativa honey) were evaluated for their bactericidal/bacteriostatic activities against both methicillin resistant and sensitive S. aureus. The inhibitory effect of honey on bacterial growth was evident at concentrations of 20% and 10% (v/v). Manuka Honey showed the best results. Manuka Honey UMF +20 had a bactericidal effect on both methicillin resistant and sensitive S. aureus. However, Sidr and N. sativa honey exerted only a bacteriostatic effect. The efficacy of different types of honey against S. aureus was dependent on the type of honey and the concentration at which it was administered. Manuka Honey had the best bactericidal activity. Future experiments should be conducted to evaluate the effects of honey on bacterial resistance. Keywords: Manuka Honey, Sidr honey, Nigella sativa honey, Methicillin resistant Staphylococcus aureus (MRSA), Saudi Arabi

Prevalence and molecular characterization of hepatitis D virus in Saudi Arabia: A single-center study

Background/Aims: Hepatitis D virus (HDV) is a defective RNA virus that is dependent on hepatitis B surface antigen (HBsAg) for transmission and replication. HDV significance arises from the possibility of poor prognosis of hepatitis B virus (HBV) infection. In Saudi Arabia, HDV prevalence varied from 8 to 32% before the HBV vaccination program and ranged from 0 to 14.7% after the vaccination program was started. The last study, performed in 2004, showed a prevalence of 8.6% in hospital-based HBV cases and 3.3% in healthy donors. The aim of this study was to investigate the prevalence and molecular characterization of HDV in chronic hepatitis B (CHB) patients at the King Abdulaziz University Hospital in Jeddah, Saudi Arabia by molecular and serological techniques. To the best of our knowledge, this is the first study to detect HDV at the molecular level in Saudi Arabia. Patients and Methods: The study included samples from 182 CHB patients from Jeddah; 13 samples with HBsAg negative were excluded. Samples were tested for HDV-Ab, viral RNA by reverse transcriptase–polymerase chain reaction (RT-PCR) in the HDV L-Ag region and sequence analysis. Results: The mean age of the participants was 44.36 years; 75.1% of the participants were Saudi nationals, 58% were males. Nine samples were positive for HDV-Ab and four were borderline; all were subjected to RT-PCR amplification. Three of the positive HDV-Ab cases and 1 borderline case were positive by RT-PCR. All the positive cases had HBV genotype D, and the positive RT-PCR cases were positive for HBV DNA. One of the HDV viremic samples was of genotype 1 by sequencing. The prevalence of HDV in the study was 7.7%, which was lower in Saudis (6.3%) than in non-Saudis (11.9%). Conclusion: HDV coinfection does not seem to have an effect on the clinical status of the recruited CHB cases in this study. More studies are needed to investigate the genetic diversity in other areas such as the southern parts of the Kingdom

Global variation in postoperative mortality and complications after cancer surgery: a multicentre, prospective cohort study in 82 countries

© 2021 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY-NC-ND 4.0 licenseBackground: 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. Methods: This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. Findings: Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70–8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39–8·80) and upper-middle-income countries (2·06, 1·11–3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26–11·59) and upper-middle-income countries (3·89, 2·08–7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. Interpretation: Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

© 2022 The Author(s). Published by Elsevier Ltd. This is an Open Access article under the CC BY 4.0 licenseBackground: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p<0·0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63·0% vs 82·7%; OR 0·35 [0·23–0·53]; p<0·0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer. Interpretation: Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised.
