Psychosocial Characteristics and Obstetric Health of Women Attending a Specialist Substance Use Antenatal Clinic in a Large Metropolitan Hospital

Objective. This paper reports the findings comparing the obstetrical health, antenatal care, and psychosocial characteristics of pregnant women with a known history of substance dependence (n = 41) and a comparison group of pregnant women attending a general antenatal clinic (n = 47). Method. Face-to-face interviews were used to assess obstetrical health, antenatal care, physical and mental functioning, substance use, and exposure to violence. Results. The substance-dependent group had more difficulty accessing antenatal care and reported more obstetrical health complications during pregnancy. Women in the substance-dependent group were more likely to report not wanting to become pregnant and were less likely to report using birth control at the time of conception. Conclusions. The profile of pregnant women (in specialised antenatal care for substance dependence) is one of severe disadvantage and poor health. The challenge is to develop and resource innovative and effective multisectoral systems to educate women and provide effective care for both women and infants

Effects of Chemical Amendments to Swine Manure on Runoff Quality

Land-applied swine manure can be an environmental concern when runoff losses of manure constituents occur. The use of chemical amendments to mitigate these losses has been investigated for poultry litter, but materials such as swine manure have received less attention in this context, particularly at the plot scale or larger. The objective of this experiment was to evaluate the impacts of aluminum sulfate (alum; Al2(SO4)3), aluminum chloride (AlCl3), and ferric chloride (FeCl3) addition on runoff of selected constituents of land-applied swine manure. Manure was collected from feeder pigs fed a standard diet. Alum and FeCl3 were added at a stoichiometric ratio of 1.1:1 [Al:total P (TP)], and AlCl3 was added at a ratio of 1.3:1 [Al:TP]. The amended manure was incubated for six days prior to land application to fescue (Festuca arundinacea Schreber) plots. Simulated rainfall (100 mm h-1 for 0.5 h of runoff) was applied to the plots on the day of application and followed by two additional simulated rainfall events at 7 d intervals. Runoff samples were collected and analyzed for dissolved reactive phosphorus (DP), TP, ammonia nitrogen (NH3-N), nitrate nitrogen (NO3-N), total Kjeldahl nitrogen (TKN), total suspended solids (TSS), fecal coliform (FC), and 17 β-estradiol. Runoff concentrations of all constituents except NO3-N were highest for the first simulated rainfall event, approaching background levels thereafter. Relative to untreated manure, all chemical amendments were effective in reducing first-event DP, TP, and TKN concentrations. Both AlCl3 and FeCl3 reduced first-event NH3-N concentrations, and FeCl3 addition led to FC concentrations indistinguishable from the control (no manure) plots. The results indicate that these amendments have potential for promoting both environmental and agronomic benefits, implying that studies involving practicality and long-term considerations should be undertaken

Perceptions of Academic Fieldwork Coordinators Regarding the Value of Fieldwork in Emerging Areas of Practice

This study investigated the perceptions of academic fieldwork coordinators (AFWCs) regarding emerging areas of practice as fieldwork experiences for entry-level occupational therapy (OT) students. Further, this study explored several aspects of fieldwork experiences in emerging areas of practice on student personal and professional development, academic curriculum, partnering community agencies, and the profession at large. A survey designed through Qualtrics®, an electronic survey system, was sent to 163 AFWCs of fully accredited master’s and doctoral entry-level OT programs. Forty-four participants (27%) completed the 16-question survey. Significance at p \u3c .05 was found in higher levels of Bloom’s taxonomy student performance when compared to traditional areas of practice. Common perceptions found among the AFWCs related to emerging areas of practice fieldwork experiences included: improved student professional and personal skills, increased connections and collaborations across and in health care disciplines, an enhanced ability to define and understand OT. Continued opportunities for fieldwork in emerging areas of practice are essential as the profession contemplates new markets and avenues in a changing health care environment

Pretend Play and Social Engagement in Toddlers at High and Low Genetic Risk for Autism Spectrum Disorder

Toddlers with an older sibling with autism spectrum disorder (ASD) and low risk (LR) toddlers with typically-developing older siblings were observed during free play with a parent and elicited pretend with an examiner at 22-months. Functional and pretend play, children’s social engagement, and parent sensitivity were assessed during free play. Complexity of play was assessed during the elicited pretend task. Toddlers with an ASD diagnosis showed less pretend play across contexts and less social engagement with parents or the examiner than either LR toddlers or high risk toddlers without a diagnosis (HR-noASD). Lower levels of pretend play and social engagement were associated with symptom severity within the high risk group, reflecting emerging ASD in toddlerhood

Evidence for polyploidy in the globally important diazotroph Trichodesmium

Polyploidy is a well-described trait in some prokaryotic organisms; however, it is unusual in marine microbes from oligotrophic environments, which typically display a tendency towards genome streamlining. The biogeochemically significant diazotrophic cyanobacterium Trichodesmium is a potential exception. With a relatively large genome and a comparatively high proportion of non-protein-coding DNA, Trichodesmium appears to allocate relatively more resources to genetic material than closely related organisms and microbes within the same environment. Through simultaneous analysis of gene abundance and direct cell counts, we show for the first time that Trichodesmium spp. can also be highly polyploid, containing as many as 100 genome copies per cell in field-collected samples and >600 copies per cell in laboratory cultures. These findings have implications for the widespread use of the abundance of the nifH gene (encoding a subunit of the N2-fixing enzyme nitrogenase) as an approach for quantifying the abundance and distribution of marine diazotrophs. Moreover, polyploidy may combine with the unusual genomic characteristics of this genus both in reflecting evolutionary dynamics and influencing phenotypic plasticity and ecological resilience

Characterization of Retinal Structure in ATF6-Associated Achromatopsia.

PurposeMutations in six genes have been associated with achromatopsia (ACHM): CNGA3, CNGB3, PDE6H, PDE6C, GNAT2, and ATF6. ATF6 is the most recent gene to be identified, though thorough phenotyping of this genetic subtype is lacking. Here, we sought to test the hypothesis that ATF6-associated ACHM is a structurally distinct form of congenital ACHM.MethodsSeven genetically confirmed subjects from five nonconsanguineous families were recruited. Foveal hypoplasia and the integrity of the ellipsoid zone (EZ) band (a.k.a., IS/OS) were graded from optical coherence tomography (OCT) images. Images of the photoreceptor mosaic were acquired using confocal and nonconfocal split-detection adaptive optics scanning light ophthalmoscopy (AOSLO). Parafoveal cone and rod density values were calculated and compared to published normative data as well as data from two subjects harboring CNGA3 or CNGB3 mutations who were recruited for comparative purposes. Additionally, nonconfocal dark-field AOSLO images of the retinal pigment epithelium were obtained, with quantitative analysis performed in one subject with ATF6-ACHM.ResultsFoveal hypoplasia was observed in all subjects with ATF6 mutations. Absence of the EZ band within the foveal region (grade 3) or appearance of a hyporeflective zone (grade 4) was seen in all subjects with ATF6 using OCT. There was no evidence of remnant foveal cone structure using confocal AOSLO, although sporadic cone-like structures were seen in nonconfocal split-detection AOSLO. There was a lack of cone structure in the parafovea, in direct contrast to previous reports.ConclusionsOur data demonstrate a near absence of cone structure in subjects harboring ATF6 mutations. This implicates ATF6 as having a major role in cone development and suggests that at least a subset of subjects with ATF6-ACHM have markedly fewer cellular targets for cone-directed gene therapies than do subjects with CNGA3- or CNGB3-ACHM
