DESIGN: Randomised trial.
SETTING: University Hospital, Malaysia: April 2016-October 2016.
POPULATION: 331 women delivered by caesarean section.
METHOD: Participants were randomised to leaving their wound entirely exposed (n = 165) or dressed (n = 166) with a low adhesive dressing (next day removal).
MAIN OUTCOME MEASURES: Primary outcomes were superficial SSI rate (assessed by provider inspection up to hospital discharge and telephone questionnaires on days 14 and 28) and patient satisfaction with wound coverage management before hospital discharge.
RESULTS: The superficial SSI rates were 2/153 (1.3%) versus 5/157 (3.2%) (relative risk [RR] 0.4, 95% CI 0.1-2.1; P = 0.45) and patient satisfaction with wound management was 7 [5-8] versus 7 [5-8] (P = 0.81) in exposed compared with dressed study groups, respectively. In the wound-exposed patients, stated preference for wound exposure significantly increased from 35.5 to 57.5%, whereas in the wound-dressed patients, the stated preference for a dressed wound fell from 48.5 to 34.4% when assessed at recruitment (pre-randomisation) to day 28. There were no significant differences in inpatient additional dressing or gauze use for wound care, post-hospital discharge self-reported wound issues of infection, antibiotics, redness and inflammation, swollen, painful, and fluid leakage to day 28 across trial groups.
CONCLUSION: The trial is underpowered as SSI rates were lower than expected. Nevertheless, leaving caesarean wounds exposed does not appear to have detrimental effects, provided patient counselling to manage expectations is undertaken.
TWEETABLE ABSTRACT: An exposed compared with a dressed caesarean wound has a similar superficial surgical site infection rate, patient satisfaction and appearance.
DESIGN: A prospective study.
SETTING: A tertiary hospital in Malaysia.
POPULATION: A cohort of 193 term nulliparous women with intact membranes.
METHODS: Prior to labour induction, cervical fluid was obtained via a vaginal speculum and tested for IGFBP-1, followed by TVUS and finally Bishop score. After each assessment the procedure-related pain was scored from 0 to 10. Cut-off values for Bishop score and cervical length were obtained from the receiver operating characteristic (ROC) curve. Multivariable logistic regression analysis was performed.
MAIN OUTCOMES MEASURES: Vaginal delivery and vaginal delivery within 24 hours of starting induction.
RESULTS: Bedside IGFBP-1 testing is better tolerated than Bishop score, but is less well tolerated than TVUS [median (interquartile range) of pain scores: 5 (4-5) versus 6 (5-7) versus 3 (2-3), respectively; P < 0.001]. IGFBP-1 independently predicted vaginal delivery (adjusted odds ratio, AOR 5.5; 95% confidence interval, 95% CI 2.3-12.9) and vaginal delivery within 24 hours of induction (AOR 4.9; 95% CI 2.1-11.6) after controlling for Bishop score (≥4 or ≥5), cervical length (≤29 or ≤27 mm), and other significant characteristics for which the Bishop score and TVUS were not predictive of vaginal delivery after adjustment. IGFBP-1 has 81% sensitivity, 59% specificity, positive and negative predictive values of 82 and 58%, respectively, and positive and negative likelihood ratios of 2.0 and 0.3 for vaginal delivery, respectively.
CONCLUSION: IGFBP-1 better predicted vaginal delivery than BS or TVUS, and may help guide decision making regarding labour induction in nulliparous women.
TWEETABLE ABSTRACT: IGFBP-1: a stronger independent predictor of labour induction success than Bishop score or cervical sonography.
METHOD: Data from 1,538 women were analyzed. At the first visit for prenatal care, the 50-gram glucose challenge test was followed by the 75-gram glucose tolerance test in those who screened positive. GDM was diagnosed based on the WHO (1999) criteria. Maternal complete blood count was obtained at the first visit, hospitalization for birth, and after birth. Receiver operator characteristic curves were generated to establish thresholds. Multivariable logistic regression analyses were performed to establish independent predictors of GDM.
RESULTS: GDM was diagnosed in 182/1,538 (11.8%). GDM was associated with hemoglobin level, hematocrit and erythrocyte count at the first visit for prenatal care only. Hemoglobin threshold at the first visit was established at 11.5 g/dl. After adjustment, high hemoglobin [AOR 1.5 (95% CI 1.0-2.1); p = 0.027] remained predictive of GDM.
CONCLUSIONS: High maternal hemoglobin level at the first prenatal visit is independently predictive of GDM.
CASE PRESENTATION: A 64-year-old Indian male with a past history of coronary artery bypass graft surgery, congestive heart failure, and diabetes mellitus complained of worsening shortness of breath for 2 weeks. Incidentally, a transthoracic echocardiography showed a "thumb-like" mass in his right atrium extending into his right ventricle through the tricuspid valve with each systole. Abdomen magnetic resonance imaging revealed a heterogenous lobulated mass in the upper and mid-pole of his right kidney with a tumor extending into his inferior vena cava and right atrium, consistent with our diagnosis of advanced renal cell carcinoma which was later confirmed by surgical excision and histology. Radical right nephrectomy, lymph nodes clearance, inferior vena cava cavatomy, and complete tumor thrombectomy were performed successfully. Perioperatively, he did not require cardiopulmonary bypass or deep hypothermic circulatory arrest. He had no recurrence during the follow-up period for more than 2 years after surgery.
CONCLUSIONS: Advanced extension of renal cell carcinoma can occur with no apparent symptoms and be detected incidentally. In rare circumstances, atypical presentation of renal cell carcinoma should be considered in a patient presenting with right atrial mass detected by echocardiography. Renal cell carcinoma with inferior vena cava and right atrium extension is a complex surgical challenge, but excellent results can be obtained with proper patient selection, meticulous surgical techniques, and close perioperative patient care.
METHODS: Benchmark Dose (BMD) software was used to model the BMD at a lower end of a one-sided 95% confidence interval with a 10% incremental risk (BMDL10) of PAHs and HCAs from different target organ toxicities. The MOEs of PAHs and HCAs in meat and fish-based products were determined by utilising the calculated BMDL10 values and estimated daily intake of meat and fish-based products from published data.
RESULTS: The calculated BMDL10 values of PAHs (i.e. benzo[a]pyrene [BaP] and fluoranthene [FA]) and HCAs (i.e. 2-amino-3,8,dimethylimidazo[4,5-f]quinoxaline [MeIQx] and 2-amino-1-methyl-6-phenylimidazo[4,5,6]pyridine [PhIP]) ranged from 19 mg/kg bw/day to 71,801 mg/kg bw/day. The MOE of BaP ranged from 41,895 to 71,801 and that of FA ranged from 19 to 1412. As for MeIQx and PhIP, their MOEs ranged from 6,322 to 7,652 and from 2,362 to 14,390, respectively.
CONCLUSION: The MOEs of FA, MeIQx and PhIP were lower than 10,000, indicating a high concern for human health and therefore demanding effective risk management actions.
