Lack of safety data on pregnant women determines difficulty in choosing the correct biologic agent to treat psoriasis in women of childbearing potential. Studies have postulated a role of IL-23 in unexplained recurrent spontaneous abortions. This gives rise to consideration about use of anti-IL-23 drugs in treatment of psoriasis in women of childbearing potential.Marine photosynthetic microalgae are ubiquitously associated with bacteria in nature. However, the influence of these bacteria on algal cultures in bioreactors is still largely unknown. In this study, eighteen different bacterial strains were isolated from cultures of Nannochloropsis sp. CCAP211/78 in two outdoor pilot-scale tubular photobioreactors. The majority of isolates was affiliated with the classes Alphaproteobacteria and Flavobacteriia. To assess the impact of the eighteen strains on the growth of Nannochloropsis sp. CCAP211/78, 24-well plates coupled with custom-made LED boxes were used to simultaneously compare replicate axenic microalgal cultures with addition of individual bacterial isolates. Co-culturing of Nannochloropsis sp. CCAP211/78 with these strains demonstrated distinct responses, which shows that the technique we developed is an efficient method for screening the influence of harmful/beneficial bacteria. Two of the tested strains, namely a strain of Maritalea porphyrae (DMSP31) and a Labrenzia aggregata strain (YP26), significantly enhanced microalgal growth with a 14% and 12% increase of the chlorophyll concentration, respectively, whereas flavobacterial strain YP206 greatly inhibited the growth of the microalga with 28% reduction of the chlorophyll concentration. Our study suggests that algal production systems represent a ‘natural’ source to isolate and study microorganisms that can either benefit or harm algal cultures.
To document pregnancy outcome in homozygous sickle cell (SS) disease and in age-matched controls with a normal haemoglobin genotype followed from birth for up to 45years.
A total of 100000 consecutive non-operative deliveries screened for sickle cell disease at the main Government maternity hospital in Kingston, Jamaica between 1973 and 1981 detected 311 (149 female) babies with SS disease who were matched by age and gender with 250 (129 female) controls with an AA haemoglobin phenotype. These individuals have been followed from birth with prospective assessment of menarche and detailed documentation of all pregnancies.
There were 177 pregnancies in 71 SS patients and 226 pregnancies in 74 AA controls. Mothers with SS disease had more spontaneous abortions (adjusted relative risk 3.2, 95% CI 1.6-6.1), fewer live births (aRR 0.7, 95% CI 0.6-0.9) and their offspring were more likely to have a gestational age <37weeks (aRR 2.1, 95% CI 1.1-3.7) and low birthweight <2.5kg (aRR 3.0, 95% CI 1.6-5.3). GPNA supplier They were more prone to acute chest syndrome (aRR 13.7, 95% CI 4.1-45.5), urinary tract infection (aRR 12.8, 95% CI 1.3-125.9), pre-eclampsia/eclampsia (aRR 3.1, 95% CI 1.1-8.8), retained placenta (aRR 10.1, 95% CI 1.1-90.3), sepsis (Fisher’s Exact test 0.04) and pregnancy-related deaths (Fisher’s Exact test 0.02). Four of five deaths were attributable to acute chest syndrome. There was no genotypic difference in pregnancy-induced hypertension or postpartum haemorrhage.
Pregnancy in SS disease carries risks for both mother and child. The variable characteristics of pregnancy-related deaths complicate their prevention.
Pregnancy in SS disease compared with controls showed increased abortions and stillbirths, fewer live births and maternal deaths in 7% patients.

This phenomenon is well documented in nursing literature. Persistent and unresolved moral distress is frequently linked to high nursing staff turnover and shortages. Engagement in a structured hermeneutic critical reflective process facilitated identification of micro, meso, and macro factors influencing the experience of moral distress. Following this process, a theorized model was developed to illustrate interactions between influences contributing to the experience of moral distress in nurses. The model highlights where opportunities lay to take action to avoid or minimize the negative consequences of this phenomenon. Professional resilience is achieved via the conscientious development of professional identity and practice of critical reflection, as components of enculturation of nurses into the profession. Undergraduate and further nurse education activities must focus on developing the necessary attitude, confidence, and skills to address issues in practice which contribute to the experience moral distress to build resilience.Peritoneal equilibration test (PET) is the gold standard for evaluating peritoneal transport, and measurement of the drain volume after 4-h dwell time with glucose 4.25% is a simple means of evaluating failure of ultrafiltration. The study objective was to verify if the measurement of the volume drained after 4 h dwell of icodextrin at 7.5% (ICO), has a better correlation with the parameters of PET. Patients in a peritoneal dialysis program (N = 35) underwent three procedures PET; determination of the drain volume after a 4-h dwell with glucose 4.25%; and determination of the drain volume after a 4-h dwell with ICO. Among patients who were classified as high transporters, the ultrafiltration volume was greater after ICO use. The ICO ultrafiltration volume correlated negatively with the ratio between the 4- and 0-h dialysate glucose concentrations (D4/D0 ratio, r = -0.579; P = 0.002), correlating positively with the dialysate-to-plasma ratio for creatinine (D/PCr ratio, r = 0.474; P = 0.002). For ICO, the area under the receiver operating characteristic curve was 0.867 and 0.792 for the D/PCr and D4/D0 ratios (P less then 0.0001 and P = 0.004, respectively), compared with 0.738 and 0.710 for glucose 4.25% (P = 0.020 and P = 0.041, respectively). A cut-off volume of 141 mL discriminated high/high-average transporters from low/low-average transporters. Volume drained after ICO use better predicts peritoneal transport patterns than does that drained after the use of glucose 4.25%.
