Comparison of the diagnostic potential of three anti-citrullinated protein antibodies as adjuncts to rheumatoid factor and CCP in a cohort of South African rheumatoid arthritis patients.

PURPOSE: A retrospective comparison of the prevalence and diagnostic value of anti-Sa, anti-CEP-1, and anti-MCV autoantibodies relative to those of the established autoantibodies, composite RF and anti-CCP-IgG used routinely for RA diagnosis as a component of the ACR 2010 criteria, in a cohort of disease-modifying anti-rheumatic drug naïve African RA patients (n = 75). METHODS: Serum concentrations of anti-Sa, anti-CEP-1 and anti-MCV autoantibodies were measured using ELISA procedures, while anti-CCP-IgG antibodies were determined by fluorescence enzyme immunoassay, and composite RF by latex-enhanced laser nephelometry. RESULTS: The seropositivity frequencies of anti-Sa, anti-CEP-1 and anti-MCV antibodies for the RA patients were 82, 72, 85%, respectively, while that of anti-CCP-IgG and RF was 87% for both. Overall, anti-MCV demonstrated the best specificity, positive predictive value (PPV), odds ratio and positive likelihood ratio of all the types of autoantibody tested. CONCLUSION: These observations in this unique cohort of RA patients indicated novel associations of all three autoantibodies in regard to HLA-SE risk alleles, disease severity and tobacco use that were not reported before. Elevated anti-Sa titers designated a propensity of higher disease and high-risk alleles in our cohort. Anti-CEP-1 association with HLA-SE homozygosity and high-risk alleles is also novel in this group. Of note, measurement of anti-MCV antibodies on presentation, either as an adjunctive or even as a stand-alone test, surpassed all other biomarkers investigated here and, therefore, may add value to clinical management.

Exogenous protease supplementation of poultry by-product meal-based diets for broilers: Effects on growth, carcass characteristics and nutrient digestibility.

An experiment was conducted to investigate the effects of three levels (0%, 3% and 6%) of poultry by-product meal (PBM) with or without protease on broiler growth, carcass characteristics and nutrient digestibility from 1 to 35 days. Two hundred and forty birds (n = 240) were fed equi-caloric and equi-nitrogenous (ME 2850 kcal/kg; CP 20%) diets throughout the experiment. The enzyme supplementation increased feed intake (p < .01) and body weight gain (p < .01), but feed:gain remained unaffected (p > .05) from 1 to 21 days. Increasing level of PBM decreased feed intake (p < .05), but body weight gain was improved (p < .05) at 3% PBM level during 1 to 21 days. The feed:gain was improved (p < .05) in birds fed diets containing 3% PBM. The feed:gain was also improved in birds fed diets containing 3% PBM from 1 to 35 days. However, feed intake and body weight gain in birds fed diets containing PBM remained unaffected. An interaction (p < .01) on feed intake between enzyme and PBM was noticed during 1 to 21 days. However, no interaction was recorded for body weight gain and feed:gain. The per cent carcass yield improved (p < .01) in birds fed diets supplemented with enzyme. The per cent breast meat yield was depressed (p < .005) in birds fed diets containing PBM. Apparent metabolizable energy (p < .001), nitrogen retention (p < .01), apparent metabolizable energy corrected for nitrogen (p < .001), and apparent digestibility coefficient for nitrogen (p < .01) improved in birds fed diets containing enzyme; however, a reverse was noticed in those fed diets containing only PBM. In conclusion, inclusion of 3% PBM along with supplementation of exogenous protease improved performance and nutrient digestibility in broilers.

Polarization attraction of 10-Gb/s NRZ-BPSK signal in a highly nonlinear fiber.

Polarization attraction of a 10-Gb/s non-return-to-zero binary phase-shift keyed (NRZ-BPSK) signal has been successfully demonstrated for the first time in a counter-propagating beam configuration using a continuous-wave pump, in a highly nonlinear fiber, by utilizing the Kerr nonlinear cross-polarization process inherent to that fiber. The efficacy of mitigating polarization-dependent loss across polarization-sensitive devices was emulated with a linear polarizer located before the receiver. The receiver sensitivity penalty at 10-9 bit-error-rate relative to the baseline NRZ-BPSK signal was < 0.5 dB, when polarization attraction was employed for a polarization-scrambled signal (after achieving a degree of polarization > 90%). The results confirm that polarization attraction is independent of modulation format.

Study of anticancer and antibacterial activities of Foeniculum vulgare, Justicia adhatoda and Urtica dioica as natural curatives.

High-throughput technologies, such as synthetic biology and genomics have paved new paths for discovery and utility of medicinally beneficial plants. Bioactive molecules isolated from different plants have significantly higher biological activities. The present study was done to analyze antibacterial potential of some medicinal plants against multi drug resistant (MDR) pathogens and anticancer effect against MCF-7 cell line. Methanolic and ethanolic extracts were tested for their antibacterial activity by disc diffusion method against six MDR bacterial strains and for cytotoxicity evaluation by MTT assay. Ethanolic extracts of the three tested plants exhibited growth inhibitory effect against Klebsiella pneumonia, Serratia marcescens and Methicillin-resistant S. aureus. Pseudomonas aeruginosa was more resistant to all extracts as its growth was least inhibited by the extracts of all tested plants. Ethanol extract of Foeniculum vulgare exhibited significant inhibition of cancer cells proliferation. Methanol extract of Justicia adhatoda also showed considerable inhibition of cancer cells. Future studies must converge on detailed investigation of modes of action of extracts of tested plants.

Anticancer activity of Cynodon dactylon and Oxalis corniculata on Hep2 cell line.

Bioactive chemicals isolated from plants have attracted considerable attention over the years and overwhelmingly increasing laboratory findings are emphasizing on tumor suppressing properties of these natural agents in genetically and chemically induced animal carcinogenesis models. We studied in vitro anticancer activity of organic extracts of Cynodon dactylon and Oxalis corniculata on Hep2 cell line and it was compared with normal human corneal epithelial cells (HCEC) by using MTT assay. Real Time PCR was conducted for p53 and PTEN genes in treated cancer cell line. DNA fragmentation assay was also carried out to note DNA damaging effects of the extracts. The minimally effective concentration of ethanolic extract of Cynodon dactylon and methanolic extract of Oxalis corniculata that was nontoxic to HCEC but toxic to Hep2 was recorded (IC50) at a concentration of 0.042mg/ml (49.48 % cell death) and 0.048mg/ml (47.93% cell death) respectively, which was comparable to the positive control. Our results indicated dose dependent increase in cell death. P53 and PTEN did not show significant increase in treated cell line. Moreover, DNA damaging effects were also not detected in treated cancer cell line. Anticancer activity of these plants on the cancer cell line showed the presence of anticancer components which should be characterized to be used as anticancer therapy.

Successful treatment of generalized granuloma annulare with adalimumab.

We report the case of a 64 year-old woman who demonstrated resolution of recalcitrant, generalized granuloma annulare (GA) following treatment with adalimumab. After showing little response to other treatment techniques, such as steroids and a triple antibiotic regimen, the patient was started on adalimumab. Within 3 months, she showed almost complete resolution of lesions. Within 6 months, she was completely lesion-free, and remained clear following 12 months of adalimumab therapy. This case provides further evidence that tumour necrosis factor-α inhibitors may be a treatment option for patients with recalcitrant, generalized GA.

Preliminary 1 month stability screening of cosmetic multiple emulsions (W/O/W) prepared using cetyl dimethicone copolyol and Polysorbate 80.

OBJECTIVES: The objective of this work was to develop W/O/W emulsions with different concentration of paraffin oil, lipophilic (cetyl dimethicone copolyol) and hydrophilic emulsifiers (polysorbate 80) and to check their stability at different storage conditions. METHODS: Approximately, 20 formulations (W/O/W) multiple emulsions were prepared, and their stability was checked at different storage conditions for the period of 30 days. Stability of some multiple emulsions ME12, ME13, ME14, ME19 and ME20 was also checked with carbomer as viscosity-enhancing agent. Microscopic analysis for droplet size determination and rheological characterization of most stable multiple emulsions, that is, ME20 were also performed. RESULTS: It was observed that stability of multiple emulsion increases with the addition of gelling agent. Formulation (ME20) with 13.6% paraffin oil, 2.4% cetyl dimethicone copolyol and 0.8% polysorbate 80 was found more stable at 25°C and 40°C for the period of 30 days. Rheological analysis indicated a decrease in viscosity with the passage of time, while droplet size analysis indicated an increase in droplet size with the passage of time. CONCLUSION: As a conclusion of this work, a stable multiple emulsion with 13.6% paraffin oil, 2.4% cetyl dimethicone copolyol and 0.8% polysorbate 80 can be formulated and can be further studied for any active ingredient for cosmetic purposes.

Polarization-insensitive all-optical dual pump-phase transmultiplexing from 2 × 10-GBd OOKs to 10-GBd RZ-QPSK using cross-phase modulation in a birefringent nonlinear PCF.

Polarization-insensitive (PI) all-optical dual pump-phase transmultiplexing from 2 × 10-GBd OOKs to 10-GBd RZ-QPSK was successfully demonstrated in a birefringent nonlinear photonic crystal fiber (PCF), by utilizing cross-phase modulation (XPM) and the inherent birefringence of the device, for the first time. PI operation was achieved by launching the probe and one pump off-axis while the state of polarization (SOP) of the other pump was randomized. Optimum pump-probe detuning, all within the C-Band, was also utilized to reduce the polarization-induced power fluctuation. Receiver sensitivity penalty at 10-9 bit-error-rate was < 5.5 dB in PI operation, relative to the FPGA-precoded RZ-DQPSK baseline.

A population-based cohort study of the effect of Caesarean section on subsequent fertility.

STUDY QUESTION: Is there an association between Caesarean section and subsequent fertility? SUMMARY ANSWER: There is no or only a slight effect of Caesarean section on future fertility. WHAT IS KNOWN ALREADY: Previous studies have reported that delivery by a Caesarean section is associated with fewer subsequent pregnancies and longer inter-pregnancy intervals. The interpretation of these findings is difficult because of significant weaknesses in study designs and analytical methods, notably the potential effect of the indication for Caesarean section on subsequent delivery. STUDY DESIGN, SIZE, DURATION: Retrospective cohort study of 1 047 644 first births to low-risk women using routinely collected, national administrative data of deliveries in English maternity units between 1 April 2000 and 31 March 2012. PARTICIPANTS/MATERIALS, SETTING, METHODS: Primiparous women aged 15-40 years who had a singleton, term, live birth in the English National Health Service were included. Women with high-risk pregnancies involving placenta praevia, pre-eclampsia, eclampsia (gestational or pre-existing), hypertension or diabetes were excluded from the main analysis. Kaplan-Meier analyses and Cox proportional hazard models were used to assess the effect of mode of delivery on time to subsequent birth, adjusted for age, ethnicity, socio-economic deprivation and year of index delivery. MAIN RESULTS AND THE ROLE OF CHANCE: Among low-risk primiparous women, 224 024 (21.4%) were delivered by Caesarean section. The Kaplan-Meier estimate of the subsequent birth rate at 10 years for the cohort was 74.7%. Compared with vaginal delivery, subsequent birth rates were marginally lower after elective Caesarean for breech (adjusted hazard ratio, HR 0.96, 95% CI 0.94-0.98). Larger effects were observed after elective Caesarean for other indications (adjusted HR 0.81, 95% CI 0.78-0.83), and emergency Caesarean (adjusted HR 0.91, 95% CI 0.90-0.93). The effect was smallest for elective Caesarean for breech, and this was not statistically significant in women younger than 30 years of age (adjusted HR 0.98, 95% CI 0.96-1.01). LIMITATIONS, REASONS FOR CAUTION: We used birth cohorts from maternity units with good quality parity information. The data are likely to be nationally representative because the characteristics of the deliveries in included and omitted units were similar. There may be residual bias in our adjusted results due to unmeasured maternal factors such as obesity and voluntary absence of conception. Any residual bias would lead to an overestimate of the effect of Caesarean section on fertility, and the true effect is therefore likely to be smaller than the effect reported in our study. WIDER IMPLICATIONS OF THE FINDINGS: Our results provide strong evidence that there is no or only a slight effect of Caesarean section on future fertility. The clinical and social circumstances leading to the Caesarean section have a greater effect on future fertility than the Caesarean section itself. This finding is important in light of rising Caesarean section rates.

Antibiotic de-escalation in bacteremic urinary tract infections: potential opportunities and effect on outcome.

PURPOSE: The aim of this study was to examine the safety and efficacy of antibiotic de-escalation in patients admitted with bacteremic urinary tract infection (UTI). METHODS: A retrospective chart review of patients admitted to a community-hospital in West Texas with bacteremic UTI during the year 2008. Antibiotic de-escalation was defined as changing the intravenous empiric antibiotic regimen to a culture-directed single agent, given intravenously or orally, with a narrower spectrum than the original empiric regimen. RESULTS: Ninety-seven patients were admitted with bacteremic UTI. Thirty-two patients were not eligible for de-escalation. Among the 65 patients who were eligible for de-escalation, the treating physicians failed to de-escalate antibiotics in 31 cases (47.7%). Fluoroquinolones' resistance, bacteria other than Escherichia coli and discharge to long-term care facilities predicted failure to de-escalate antibiotics. On multivariate analysis, discharge to long-term care facility was the only risk factor that predicted failure to de-escalate antibiotics. The difference between mean hospital length of stay and mortality between the above two groups was not statistically significant. CONCLUSION: Antibiotic de-escalation is under-recognized and sporadically practiced. In patients admitted with bacteremic UTI, empiric antibiotic regimen can be changed to a culture-directed single antibiotic without an increase in hospital length of stay or patients' mortality.

Association between maternal body mass index during pregnancy, short-term morbidity, and increased health service costs: a population-based study.

OBJECTIVE: To investigate the impact of maternal body mass index (BMI, kg/m(2)) on clinical complications, inpatient admissions, and additional short-term costs to the National Health Service (NHS) in Scotland. DESIGN: Retrospective cohort study using an unselected population database. SETTING: Obstetric units in Scotland, 2003-2010. POPULATION: A total of 124,280 singleton deliveries in 109,592 women with a maternal BMI recorded prior to 16 weeks of gestation. METHODS: Population-based retrospective cohort study of singleton deliveries, with multivariable analysis used to assess short-term morbidity and health service costs. MAIN OUTCOME MEASURES: Maternal and offspring outcomes, number and duration of hospital admissions, and healthcare costs. RESULTS: Using multivariable analysis, in comparison with women of normal weight, women who were overweight, obese, or severely obese had an increased risk of essential hypertension [1.87 (1.18-2.96), 11.90 (7.18-19.72), and 36.10 (18.33-71.10)], pregnancy-induced hypertension [1.76 (1.60-1.95), 2.98 (2.65-3.36), and 4.48 (3.57-5.63)], gestational diabetes [3.39 (2.30-4.99), 11.90 (7.54-18.79), and 67.40 (37.84-120.03)], emergency caesarean section [1.94 (1.71-2.21), 3.40 (2.91-3.96), and 14.34 (9.38-21.94)], and elective caesarean section [2.06 (1.84-2.30), 4.61 (4.06-5.24), and 17.92 (13.20-24.34)]. Compared with women of normal weight, women who were underweight, overweight, obese, or severely obese were associated with an 8, 16, 45, and 88% increase in the number of admissions, respectively, and women who were overweight, obese, or severely obese were associated with a 4, 9, and 12% increase in the duration of stay (all P < 0.001). The additional maternity costs [mean (95% CI), adjusted analyses] for women who were underweight, overweight, obese, or severely obese were £102.27 (£48.49-156.06), £59.89 (£41.61-78.17), £202.46 (£178.61-226.31), and £350.75 (£284.82-416.69), respectively. CONCLUSIONS: Maternal BMI influences maternal and neonatal morbidity, the number and duration of maternal and neonatal admissions, and health service costs.

Vaginal birth after caesarean section: a cohort study investigating factors associated with its uptake and success.

OBJECTIVES: To investigate the demographic and obstetric factors associated with the uptake and success rate of vaginal birth after caesarean section (VBAC). DESIGN: Cohort study using data from Hospital Episode Statistics. SETTING: English National Health Service. POPULATION: Women whose first birth resulted in a live singleton delivery by caesarean section between 1 April 2004 and 31 March 2011, and who had a second birth before 31 March 2012. METHODS: Logistic regression to estimate adjusted odds ratios (OR). MAIN OUTCOME MEASURES: Attempted and successful VBAC. RESULTS: Among the 143,970 women in the cohort, 75,086 (52.2%) attempted a VBAC for their second birth. Younger women, those of non-white ethnicity and those living in a more deprived area had higher rates of attempted VBAC. Overall, 47,602 women (63.4%) who attempted a VBAC had a successful vaginal birth. Younger women and women of white ethnicity had higher success rates. Black women had a particularly low success rate (OR, 0.54; 95% confidence interval [CI], 0.50-0.57). Women who had an emergency caesarean section in their first birth also had a lower VBAC success rate, particularly those with a history of failed induction of labour (OR, 0.59; 95% CI, 0.53-0.67). CONCLUSION: In this national cohort, just over one-half of women with a primary caesarean section who were eligible for a trial of labour attempted a VBAC for their second birth. Of these, almost two-thirds successfully achieved a vaginal delivery.

Impact of third- and fourth-degree perineal tears at first birth on subsequent pregnancy outcomes: a cohort study.

OBJECTIVE: To investigate, among women who have had a third- or fourth-degree perineal tear, the mode of delivery in subsequent pregnancies as well as the recurrence rate of third- or fourth-degree tears. DESIGN: A retrospective cohort study of deliveries using a national administrative database. SETTING: The English National Health Service between 1 April 2004 and 31 March 2012. POPULATION: A total of 639,402 primiparous women who had a singleton, term, vaginal live birth between April 2004 and March 2011, and a second birth before April 2012. METHODS: Multivariable logistic regression models were used to estimate odds ratios, adjusted for other risk factors. MAIN OUTCOME MEASURES: Mode of delivery and recurrence of tears at second birth. RESULTS: The rate of elective caesarean at second birth was 24.2% for women with a third- or fourth-degree tear at first birth, and 1.5% for women without (adjusted odds ratio, aOR 18.3, 95% confidence interval, 95% CI 16.4-20.4). Among women who had a vaginal delivery at second birth, the rate of third- or fourth-degree tears was 7.2% for women with a third- or fourth-degree tear at first birth, compared with 1.3% for women without (aOR 5.5, 95% CI 5.2-5.9). CONCLUSIONS: The risk of a severe perineal tear is increased five-fold in women who had a third- or fourth-degree tear in their first delivery. This increased risk should be taken into account when decisions about mode of delivery are made.

Common pathogens associated with infected diabetic foot ulcers: A retrospective cohort study in a specialized medical center in Jeddah, Saudi Arabia.

Background: Foot infections, a frequent complication of diabetes mellitus, are associated with heavy resource utilization, including antibiotic therapy and surgeries. However, the most common type of isolated pathogen in diabetic foot infections remains unknown. We aimed to identify the most common types of isolated pathogens in diabetic foot infections. Methods: This retrospective cohort study was conducted in a specialized medical center in Jeddah, Saudi Arabia. A total of 96 patients diagnosed with diabetes and presented with a foot ulcer showing clinical signs of infection were included. Results: The mean age was 63.03 ± 10.88 years, and 67.7% were males. The mean duration of diabetes diagnosis was 21.86 ± 9.66 years, and the majority had foot ulcers for over six weeks. Bacteria were present in 65 patients (67.7%), Gram-negative organisms were observed in 37 patients (38.5%), and Gram-positive organisms were present in 28 patients (29.2%). In the 65 patients with bacterial culture, Staphylococcus aureus was the most common isolated organism and was observed in 18 patients (27.7%), followed by Escherichia coli in 11 (16.9%) and Pseudomonas aeruginosa in 10 (15.4%). Binary regression analyses found that Gram-negative organisms were significantly more multidrug-resistant than Gram-positive organisms (P = 0.012, OR = 7.172, 95% CI = 1.542-33.352). Patient outcomes included healed ulcers (n = 10, 10.4%), minor amputation (n = 16, 16.7%), major amputation (n = 1, 1%), and debridement (n = 48, 50%). Conclusion: Gram-negative organisms were predominant in patients with diabetes and foot ulcers having clinical signs of infection. Treatment with an individualized antibiotic regimen is vital in ensuring optimal outcomes and preventing major amputations.

All-optical amplitude-phase transmultiplexing of RZ-OOK and RZ-BPSK to RZ-QPSK by polarization-insensitive XPM using a nonlinear birefringent AlGaAs waveguide.

Polarization-insensitive (PI) phase-transmultiplexing (PTM) of a 10-Gb/s return-to-zero ON-OFF keying (RZ-OOK) pump and a 10-Gb/s RZbinary phase-shift keying (RZ-BPSK) probe to 20-Gb/s RZ-quadrature-PSK (RZ-QPSK) has been successfully demonstrated for the first time in a passive, birefringent AlGaAs waveguide, utilizing PI cross-phase modulation (PI-XPM). For differential QPSK (DQPSK)-detection, a 10 − 9-BER pre-amplified receiver sensitivity penalty of ≈ 2.5 dB for the in-phase component and ≈ 4.9 dB for the quadrature component were found. The penalties were relative to the FPGA-precoded RZ-DQPSK baseline for a pump-probe detuning of ≈ 12 nm, when the probe state of polarization was scrambled and the pump was launched off-axis into the waveguide.

Impact of Caesarean section on subsequent fertility: a systematic review and meta-analysis.

STUDY QUESTION: Is there an association between a Caesarean section and subsequent fertility? SUMMARY ANSWER: Most studies report that fertility is reduced after Caesarean section compared with vaginal delivery. However, studies with a more robust design show smaller effects and it is uncertain whether the association is causal. WHAT IS KNOWN ALREADY: A previous systematic review published in 1996 summarizing six studies including 85 728 women suggested that Caesarean section reduces subsequent fertility. The included studies suffer from severe methodological limitations. STUDY DESIGN, SIZE, DURATION: Systematic review and meta-analysis of cohort studies comparing subsequent reproductive outcomes of women who had a Caesarean section with those who delivered vaginally. PARTICIPANTS/MATERIALS, SETTING, METHODS: Searches of Cochrane Library, Medline, Embase, CINAHL Plus and Maternity and Infant Care databases were conducted in December 2011 to identify randomized and non-randomized studies that compared the subsequent fertility outcomes after a Caesarean section and after a vaginal delivery. Eighteen cohort studies including 591 850 women matched the inclusion criteria. Risk of bias was assessed by the Newcastle-Ottawa scale (NOS). Data extraction was done independently by two reviewers. The meta-analysis was based on a random-effects model. Subgroup analyses were performed to assess whether the estimated effect was influenced by parity, risk adjustment, maternal choice, cohort period, and study quality and size. MAIN RESULTS AND THE ROLE OF CHANCE: The impact of Caesarean section on subsequent pregnancies could be analysed in 10 studies and on subsequent births in 16 studies. A meta-analysis suggests that patients who had undergone a Caesarean section had a 9% lower subsequent pregnancy rate [risk ratio (RR) 0.91, 95% confidence interval (CI) (0.87, 0.95)] and 11% lower birth rate [RR 0.89, 95% CI (0.87, 0.92)], compared with patients who had delivered vaginally. Studies that controlled for maternal age or specifically analysed primary elective Caesarean section for breech delivery, and those that were least prone to bias according to the NOS reported smaller effects. LIMITATIONS, REASONS FOR CAUTION: There is significant variation in the design and methods of included studies. Residual bias in the adjusted results is likely as no study was able to control for a number of important maternal characteristics, such as a history of infertility or maternal obesity. WIDER IMPLICATIONS OF THE FINDINGS: Further research is needed to reduce the impact of selection bias by indication through creating more comparable patient groups and applying risk adjustment.

Rates of subsequent surgery following endometrial ablation among English women with menorrhagia: population-based cohort study.

OBJECTIVE: To assess the risk of further surgery amongst women who had an initial endometrial ablation (EA) for the treatment of heavy menstrual bleeding (HMB). DESIGN: A retrospective cohort study using a national administrative database. SETTING: Population-based study of hospital care in the English National Health Service. POPULATION: A cohort of 114,910 women who had EA for HMB between January 2000 and December 2011. METHODS: Multiple Cox regressions were performed to identify the risks of a further procedure, adjusted for age, social deprivation, year and type of initial EA, and presence of fibroids/polyps. MAIN OUTCOME MEASURES: Time to repeat EA or hysterectomy after initial surgery. RESULTS: Of 114,910 women undergoing EA, 16.7% had at least one subsequent procedure within 5 years. Higher rates of subsequent surgery were associated with younger age at initial EA, with women aged under 35 years having an adjusted hazard ratio of 2.83 (95% CI 2.67-2.99), compared with women aged over 45 years. Women who had radiofrequency ablation were less likely to have subsequent surgery as compared with first-generation techniques (HR 0.69, 95% CI 0.63-0.76). The rate of a subsequent hysterectomy within 5 years was 13.5%. Younger women (OR 0.59, 95% CI 0.51-0.69) and those who had balloon, microwave, or radiofrequency ablation were less likely to have a second EA procedure, rather than a hysterectomy. CONCLUSIONS: One in six women have further surgery after EA for HMB, which is a higher rate than reported in clinical trials. This risk of further surgery decreases with age.

Third- and fourth-degree perineal tears among primiparous women in England between 2000 and 2012: time trends and risk factors.

OBJECTIVE: To describe the trends of severe perineal tears in England and to investigate to what extent the changes in related risk factors could explain the observed trends. DESIGN: A retrospective cohort study of singleton deliveries from a national administrative database. SETTING: The English National Health Service between 1 April 2000 and 31 March 2012. POPULATION: A cohort of 1 035 253 primiparous women who had a singleton, term, cephalic, vaginal birth. METHODS: Multivariable logistic regression was used to estimate the impact of financial year of birth (labelled by starting year), adjusting for major risk factors. MAIN OUTCOME MEASURE: The rate of third-degree (anal sphincter is torn) or fourth-degree (anal sphincter as well as rectal mucosa are torn) perineal tears. RESULTS: The rate of reported third- or fourth-degree perineal tears tripled from 1.8 to 5.9% during the study period. The rate of episiotomy varied between 30 and 36%. An increasing proportion of ventouse deliveries (from 67.8 to 78.6%) and non-instrumental deliveries (from 15.1 to 19.1%) were assisted by an episiotomy. A higher risk of third- or fourth-degree perineal tears was associated with a maternal age above 25 years, instrumental delivery (forceps and ventouse), especially without episiotomy, Asian ethnicity, a more affluent socio-economic status, higher birthweight, and shoulder dystocia. CONCLUSIONS: Changes in major risk factors are unlikely explanations for the observed increase in the rate of third- or fourth-degree tears. The improved recognition of tears following the implementation of a standardised classification of perineal tears is the most likely explanation.

Glasgow Coma Score Predicting the Poor Outcome of the Patients Presenting Fever with Altered Sensorium.

To assess the role of the Glasgow Comma Score (GCS) for predicting the outcome of the patient with fever and altered sensorium was the objective of the study. This prospective observational study was conducted for six months following ethical approval. Informed consent was obtained prior enrollment. A total of 50 patients with complaints of fever for <2 weeks duration with altered sensorium with or without seizure were included in the study. GCS was calculated for all patients just after admission and before starting interventions. All patients were investigated and managed according to the hospital protocol. The outcome of the patients (living or dead within the hospital) was evaluated against the admission GCS score. The study was performed in accordance with the current Declaration of Helsinki. Of all, 42.0% (n=21) of the patients had bacterial meningitis, followed by viral encephalitis, cerebral malaria and coma vigil. Complete recovery occurred in 60.0% of cases, while recovery with disability occurred in 28.0% of cases. Death occurred in 12.0% of cases (n=6) due to cerebral malaria, viral encephalitis and bacterial meningitis (n=2 each cause). A higher number of deaths occurred in the lower GCS group (n=5 in GCS group 3-5) and this difference was statistically significant (p<0.05). Moreover, considering death as an outcome, multivariate logistic regression showed that GCS (OR 70.598, 95% CI-1.243-4009.41; p=0.039) was an independent predictor of the outcome. GCS seemed to be a predictor of the short-term outcome of the patient presenting with fever and altered sensorium in our setting. However, further exploration in larger setting with appropriate study design is recommended.
