Modified Early Warning Score (MEWS) as a predictor of intensive care unit admission in cancer patient on chemotherapy with positive blood culture: A retrospective cohort study.

BACKGROUND: Although the usefulness of the Modified Early Warning Score (MEWS) in predicting clinical deterioration or the need for intensive care unit (ICU) admission has been evaluated in several studies, only few reports have considered the immune status of the patient. Patients receiving chemotherapy for cancer are at risk of sepsis. This study aimed to assess the validity of MEWS in predicting clinical deterioration, ICU admission, and mortality among immunocompromised cancer patients on chemotherapy (CPOC). METHODS: This retrospective cohort study was conducted at a tertiary care center in Jeddah, Saudi Arabia. Subjects aged>14 years with positive blood cultures, who were hospitalized between June 2016 and June 2017, were included. MEWS was calculated at different time intervals: before, after, and at the time (0-time) of positive blood culture. RESULTS: Overall, 192 patients were enrolled, including 89 CPOC and 103 immunocompetent individuals (controls). ICU admission rate was significantly lower in the CPOC group than in the control group (21 % vs. 50 %, P < .001). Positive MEWS rate (score ≥4) at 0-time was lower in the CPOC group, but the difference was not significant (39.7 % vs. 60.3 %, P = .129). In the CPOC group, positive MEWS rate (score ≥4) had a sensitivity, specificity, positive predictive value, and negative predictive value of 52.6 %, 70 %, 32.3 %, and 84 %, respectively, which was comparable to that observed in the control group. Furthermore, the receiver operating characteristic curve in the CPOC group showed that MEWS calculated 12-36 h before positive blood culture was a significant predictor of ICU admission. The optimal threshold of MEWS with the best sensitivity and specificity was ≥ 3 for the CPOC group and ≥ 4 for the control group to predict ICU admission. MEWS was a generally poor predictor of mortality. CONCLUSION: MEWS ≥ 3 calculated 12-36 h before positive blood culture is the best predictor of ICU admission for CPOC.

Smoking behaviour after enforcement of a 100% tax on tobacco products in Saudi Arabia: a cross-sectional study.

BACKGROUND: Raising the prices of cigarettes is a common intervention to control tobacco use. In June 2017, Saudi Arabia imposed a 100% excise tax on tobacco products and energy drinks. AIMS: This study aimed to evaluate the impact of the increase in prices on tobacco products and the resulting cigarette smoking behaviour in Jeddah, Saudi Arabia before and after the increase in tobacco product prices. METHODS: This cross-sectional study was conducted between December 2017 and March 2018 in Saudi Arabian smokers aged 18 years and more. A validated questionnaire was distributed to a convenience sample in public places and through Twitter. The McNemar matched pairs chi-squared test was used to evaluate the self-reported difference in cigarette smoking before and after the tax came into effect. Binary logistic regression analysis was done to identify the socioeconomic and health factors associated with stopping smoking. RESULTS: In all, 376 participants (80.0% men) completed the questionnaire. A large proportion of the participants (39.6%) reported no change in their smoking behaviour after the tax was imposed, whereas 29.8% switched to cheaper brands. Before the tax, 154 participants smoked 15 cigarettes or more a day; this figure decreased to 134 after the tax (McNemar test, P < 0.001). Respondents who were married, unemployed, had a higher income or who rated their health as fair were significantly more likely to have stopped smoking after the tax. CONCLUSION: The sharp increase in cigarette prices in Saudi Arabia has led to a statistically significant reduction in smoking. Future research should assess the long-term effects of this intervention on smoking onset, prevalence and relapse.

Biliary atresia with an unusual abdominal orientation: A case report.

INTRODUCTION: Biliary atresia (BA) is a rare condition where the hepatic or common bile ducts get obliterated by fibrous tissue for unknown causes. It is diagnosed in 5-10 per 100,000 live births worldwide in whom liver injury and death are definite if untreated. PRESENTATION: We report a case of BA with associated malrotation and situs ambiguous discovered incidentally during Kasai procedure. The small intestine was found to be malrotated with the duodenojejunal junction to the right of the vertebral column. The liver, stomach, and spleen were in the center, right side, and left side of the abdomen respectively. The malrotation was corrected by performing a Ladd's procedure in addition to the Kasai. She had an uneventful postoperative course. At follow-up on the second, sixth and 12th weeks postoperatively, she had normal stool color and liver function. DISCUSSION: BA patients with associated structural anomalies might have a worse outcome after the Kasai procedure. Several studies demonstrated that the coexistence of malrotation with BA to be in the range of 0.3%-9.4% among BA patients. Also, the presence of situs abnormalities with BA has been reported in some studies to be present in 0.01-0.045% of BA cases. However, the presentation of BA with both situs inversus and intestinal malrotation has seldom been reported. CONCLUSION: The diagnosis of BA should prompt further investigation for other anatomical abnormalities as the presence of which might affect the management plan.

Hoarseness of Voice as a Rare Presentation of Tuberculosis: A Case Report Study.

BACKGROUND: Having hoarseness of voice as the first clinical manifestation of tuberculosis is rare. This atypical presentation causes some confusion since other more common conditions, such as laryngeal carcinoma, present similarly and might require more invasive tests to confirm the diagnosis. CASE PRESENTATION: A 38-year-old male presented to the otorhinolaryngology clinic with a four-month history of change in voice. Laryngoscopy demonstrated a right glottic mass, raising suspicion of laryngeal cancer. The computed tomography showed a mass and incidental finding of opacities in lung apices. Chest x-ray demonstrated findings suggestive of tuberculosis. Polymerase chain reaction and culture of sputum samples confirmed the diagnosis and the patient was started on anti-tuberculosis treatment. CONCLUSION: Despite accounting for only 1% of pulmonary tuberculosis cases and having a similar presentation to laryngeal carcinoma, we recommend considering laryngeal tuberculosis when evaluating hoarseness of voice in endemic areas.
