Psammoperca datnioides Richardson 1848, long considered a synonym of P. waigiensis (Cuvier in Cuvier & Valenciennes 1828), is redescribed as a valid species of Psammoperca Richardson 1848. The species is likely to be endemic to Australia, where it was formerly considered to be P. waigiensis, but differs from P. waigiensis in having the following characters: more slender body (mean depth 28.9% of SL vs. mean depth 36.7% of SL in P. waigiensis), pored lateral-line scales 49–54 (vs. 46–48 in P. waigiensis), scale rows above and below lateral line 6½ / 10½–11½ (vs 4½ / 9½–10½ in P. waigiensis), and vertical at hind margin of maxilla posterior/behind center of eye (vs. vertical at hind margin of maxilla anterior to/in front of hind margin of eye in P. waigiensis). Live specimens of Psammoperca datnioides have a uniformly dense black or brownish body, with this dark colour on body scales and pored lateral-line scales persisting even in preserved specimens. Live specimens of Psammoperca waigiensis have a brownish body, often golden in colour, and pored lateral-line scales that are yellow-edged. The COI sequence (cytochrome c oxidase subunit I, 612 bp) of P. datnioides also is distinct from P. waigiensis, and the related and poorly known Hypopterus macropterus (Günther 1859). The latter species is redescribed and diagnosed with eight indistinct dark bands on the head and body, and dorsal-fin rays VII-I, 14–15 (vs. no dark bands and dorsal-fin rays VII-I, 12–13 in Psammoperca). Nominal species in the genus Psammoperca are discussed and Cnidon chinensis Müller & Troschel 1849 (type locality: Manila, Philippines) is included as a junior synonym of P. waigiensis. Psammoperca vaigiensis Boulenger 1895 is an unneeded emendation and thus an invalid name. Psammoperca macroptera Günther 1859 is retained in the monotypic genus Hypopterus Gill 1861 in the family Latidae, although the species has been overlooked in most studies on the Latidae and/or Centropomidae. A key to the Latidae is provided.
Evaluation of a Time-Dependent Model for the Intensification of Tropical Cyclones

Abstract
Axisymmetric and three-dimensional simulations are used to evaluate the theory of tropical cyclone (TC) intensification proposed by K. A. Emanuel, which is based on gradient wind balance and moist-neutral ascent along angular momentum (M) surfaces. According to the numerical model results, the intensification of the TC can be divided into two periods, phase I and phase II. During phase I, the TC intensifies while the M and saturation entropy (s*) surfaces evolve from nearly orthogonal to almost congruent. During phase II, the M and s* surfaces in the eyewall and outflow are congruent as the TC intensifies, which is consistent with Emanuel’s study. Therefore, the condition of moist slantwise neutrality in Emanuel’s study is sufficiently satisfied throughout the intensification in phase II. It is also found that the sensitivity of the intensification rates to the surface exchange coefficient for entropy Ck matches Emanuel’s theoretical result, which is that the intensification rate is proportional to Ck. However, the intensification rate varies in proportion to the surface exchange coefficient for momentum Cd, while the Emanuel model growth rate is insensitive to Cd. Furthermore, although the tendency diagnosed by Emanuel is qualitatively similar to the numerical model result during phase II, it is not quantitatively similar. The present analysis finds the inclusion of non–gradient wind effects in the theoretical framework of Emanuel’s study produces an intensification rate that is quantitatively similar to the numerical model results. The neglect of non–gradient wind effects in Emanuel’s study may be the reason for the different dependence of its intensification rate on Cd compared to that of the numerical model. Other aspects of Emanuel’s study in the context of recent research on TC intensification are discussed.
Comment on “Abyssal Upwelling and Downwelling Driven by Near-Boundary Mixing”
Authors: Ledwell James R. 
Published: March 2018

AbstractMcDougall and Ferrari have estimated the global deep upward diapycnal flow in the boundary layer overlying continental slopes that must balance both downward diapycnal flow in the deep interior and the formation of bottom water around Antarctica. The decrease of perimeter of isopycnal surfaces with depth and the observed decay with height above bottom of turbulent dissipation in the deep ocean play a key role in their estimate. They argue that because the perimeter of seamounts increases with depth, the net effect of mixing around seamounts is to produce net downward diapycnal flow. While this is true along much of a seamount, it is shown here that diapycnal flow of the densest water around the seamount is upward, with buoyancy being transferred from water just above. The same is true for midocean ridges, whose perimeter is constant with depth. It is argued that mixing around seamounts and especially midocean ridges contributes positively to the global deep overturning circulation, reducing the amount of turbulence demanded over the continental slopes to balance the buoyancy budget for the bottom and deep water.
Shelf Flows Forced by Deep-Ocean Anticyclonic Eddies at the Shelf Break
Authors: Cherian Deepak A. , Brink K. H. 
Published: March 2018

AbstractIsolated monopolar eddies in the ocean tend to move westward. Those shed by western boundary currents may then interact with the continental margin. This simple picture is complicated by the presence of other flow features, but satellite observations show that many western boundary continental shelves experience cross-shelfbreak exchange flows forced by mesoscale eddies translating near the shelf break. Here we extend our previous study of eddy interaction with a flat shelf to that with a sloping shelf. Using a set of primitive equation numerical simulations, we address the vertical structure of the onshore and offshore flows forced by the eddy, the origin of the exported shelf water, and the extent to which eddy water can penetrate onto the shelf. The simulations reveal an asymmetry in the vertical structure of cross-shelfbreak flows: the offshore flow is generally barotropic, whereas the onshore flow is always baroclinic. The exported shelf water is sourced from downstream of the eddy in the coastal-trapped wave direction and is supplied by a barotropic alongshore jet. This “supply jet” has a Rhines-like cross-shore length scale proportional to (eddy velocity scale/shelf topographic beta)1/2 measured from the shelf break. Eddy water is forced onto the shelf and is present up to a distance of one internal Rossby deformation radius, defined using shelf properties, from the shelf break. We rationalize these horizontal and vertical scales, connect them to existing observations, and extend our previous parameterization of eddy-forced offshore shelf-water flux to account for nonzero shelf slopes.

Published: March 2018

Aim: The aim of this study was to assess sociodemographic factors and factors connected with treatment of mental illness and to decide whether they can influence the level of self-stigma. Method: Sociodemographic characteristics (age, gender, family status, level of employment, level of education) and characteristics related to illness and treatment (diagnosis, length of treatment, adherence to treatment) were gathered in a group of patients in stable mental condition, without acute symptoms of mental illness. Self-stigma was measured using the Self-stigma of Mental Illness Scale – short form (SSMIS-SF). Results: The sample included 197 patients: 99 patients in group 1 (G1) with psychosis and 98 in group 2 (G2) with anxious and affective disorders. The average age was 44.15 ± 12.91 years, the length of illness was 11.67 ± 9.21 years and 48% of patients were men. The total average SSMIS-SF score was 61.54 ± 23.34. We found no statistically significant difference in the total level of self-stigmatisation between these groups ( t(197) = 0.77; p = .441). The level of self-stigmatisation (total score of SSMIS-SF) in patients in G1 (psychosis) increased with the length of illness r(99) = .253; p = .011. Employment status seems to correlate with the level of self-stigmatisation ( F(3, 184) = 5.27; p = .002). Patients unemployed and on disability pension had higher levels of self-stigmatisation than patients working full-time. Patients who took medication regularly (full medical adherence) had lower scores of SSMIS-SF total scores in comparison with patients with lower compliance ( t(195) = 3.476; p = .001; Cohen’s d = .25). Conclusion: According to our results, with regard to the factors that were followed, self-stigmatisation correlates with the presence of employment (social inclusion), duration of illness in patients with psychosis and treatment adherence. We did not find a statistically significant influence of age, gender, marital status or clinical diagnosis on the level of self-stigma.

Published: March 2018

Background: The American Academy of Pediatrics and the National Academy of Medicine recommend vitamin D supplementation for breastfeeding infants. However, compliance with this recommendation is poor. Maternal supplementation with vitamin D is a safe and effective alternative to achieving vitamin D sufficiency in breastfeeding infants, and mothers have indicated a preference for self-supplementation over infant supplementation. Research aim: We sought to explore Family Medicine clinicians’ knowledge, attitudes, and practices regarding vitamin D supplementation recommendations for breastfeeding dyads. Methods: Fifty-six Family Medicine clinicians (including faculty physicians, resident physicians, and nurse practitioners/physician assistants) completed an online, anonymous survey regarding their knowledge and practices concerning vitamin D supplementation for breastfeeding infants. Results: The vast majority of clinicians (92.9%) correctly identified the American Academy of Pediatrics’ 2008 recommended dose for vitamin D supplementation in breastfeeding infants and estimated recommending vitamin D supplementation of exclusively breastfeeding infants 70.1% of the time. If all options were equivalent, clinicians would prefer to offer maternal or infant supplementation (50%) or maternal supplementation (37.5%) over infant supplementation (12.5%). Most (69.6%) preferred daily over monthly supplementation regimens. Conclusion: Family Medicine clinicians are knowledgeable regarding current recommendations for vitamin D supplementation in breastfeeding infants. They are also open to recommending maternal supplementation or offering parents a choice of maternal or infant vitamin supplementation.

Purpose: Development of a new, fiber-free, single-use endo-illuminator for pars plana vitrectomy as a replacement for fiber-based systems with external light sources. The hand-guided intraocularly placed white micro light-emitting diode is evaluated for its illumination properties and potential photochemical and thermal hazards. Methods: A micro light-emitting diode was used to develop a single-use intraocular illumination system. The light-source-on-tip device was implemented in a prototype with 23G trocar compatible outer diameter of 0.6 mm. The experimental testing was performed on porcine eyes. All calculations of possible photochemical and thermal hazards during the application of the intraocular micro light-emitting diode were calculated according to DIN EN ISO 15007–2: 2014. Results: The endo-illuminator generated a homogeneous and bright illumination of the intraocular space. The color impression was physiologic and natural. Contrary to initial apprehension, the possible risk caused by inserting a light-emitting diode into the intraocular vitreous was much smaller when compared to conventional fiber-based illumination systems. The photochemical and thermal hazards allowed a continuous exposure time to the retina of at least 4.7 h. Conclusion: This first intraocular light source showed that a light-emitting diode can be introduced into the eye. The system can be built as single-use illumination system. This light-source-on-tip light-emitting diode–endo-illumination combines a chandelier wide-angle illumination with an adjustable endo-illuminator.
Alternative surgical procedure for treating superior vena cava syndrome in a hemodialysis patient

Published: March 2018

Background: The incidence of superior vena cava syndrome has been increasing in hemodialysis patients with the widespread use of dialysis catheters. Although endovascular intervention remains the primary choice for treatment, the long-term patency rate is not optimistic. Occlusive lesions are often encountered that cannot be opened using this intervention. Therefore, we chose to present this case involving a pericardial patch used to reconstruct the superior vena cava in the treatment of catheter-associated chronic superior vena cava occlusion. Methods: Here, we report a case of facial swelling and severe bilateral pleural effusion secondary to superior vena cava occlusion in a 41-year-old woman. An endovascular venous intervention was attempted initially but failed. Finally, we adopted a procedure using the pericardium as a patch to reconstruct the superior vena cava, maintaining most of the original anatomical structure. Results: This patient’s facial swelling and bilateral pleural effusion disappeared after the operation. In addition, her symptoms of coughing and dyspnea were relieved. The Brescia-Cimino fistula in her left forearm functioned well. Conclusion: The use of a pericardial patch to reconstruct the superior vena cava is a reliable approach in patients who are not candidates for endovascular treatment.

Published: March 2018

Background: There is a discrepancy between the reported increase in donor conversion rates and the number of organs available for transplant. Methods: Secondary analysis of data obtained from the Scientific Registry of Transplant Recipients from January 2003 through December 2015 was performed. The primary outcomes were the (1) number of brain-dead donors from whom solid organs were recovered and (2) number of the organs transplanted. Descriptive statistics and growth plots were used to examine the trajectory of organ donation, recovery, and transplantation outcomes over the 11-year period. Results: From 2003 to 2006, the number of brain-dead donors increased from 6187 to 7375, remaining relatively stable at approximately 7200 thereafter. The average eligible deaths per organ procurement organization dropped from 182.7 (standard deviation [SD]: 131.3) in 2003 to 149.3 (SD: 111.4) in 2015. This suggests a total of 12 493 unrealized potential donors (2006-2015). Conclusions: Since 2006, a steady decline in the number of donor-eligible deaths was reported. In 2003, the reported eligible deaths was 11 326. This number peaked in 2004 at 11 346, tumbling to 9781 eligible donors in 2015, despite a 9% increase in the US population. From 2006 to 2015, the data indicate an artificial depression and underestimation of the true potential of brain-dead donors in the United States of conservatively 12 493 donors or 39 728 missing organs. New metrics providing objective but verifiable counts of the donor pool are needed.
Fertility and pregnancy in cancer survivors
Authors: Tang Monica , Webber Kate 
Published: March 2018

Summary Cancer survivors are increasing as improvements in cancer diagnosis and treatment translate to improved outcomes. As cancer survivors in their reproductive years contemplate pregnancy, it is important to understand the impact of cancer and its treatment on fertility and pregnancy outcomes. Cancer treatments such as chemotherapy and radiotherapy can affect patients’ fertility, and strategies are available to help preserve the future fertility of survivors. The potential impact of previous cancer diagnoses and treatments on pregnancy and maternal and fetal outcomes needs to be assessed and discussed with survivors, with support from materno-fetal medicine specialists and high-risk antenatal services as needed.

Published: March 2018

Objectives: Corticosteroid injections (CSI) are frequently utilized in the nonoperative management of rotator cuff tears. However, recent literature suggests that injections may reduce biomechanical strength of tendons and ligaments in animal models and increase the risk of postoperative infections following surgery. The goal of this study was to determine if the timing of CSI is associated with an increased risk of reoperation following primary rotator cuff repair (RCR). Methods: A retrospective analysis of claims data of privately-insured subjects from the MarketScan® database for the years 2010-2014 was conducted. A cohort of subjects aged 18-64 who were diagnosed with a rotator cuff tear and underwent repair in 2011 was identified. Multivariable logistic regression models were used to compare the odds of reoperation between groups. Results: A total of 4,959 subjects with an arthroscopic RCR were identified. Of this, 553 subjects required reoperation within the following 3 years (Table 1). Patients who had a CSI within 6 months preceding the RCR were at a much higher risk of undergoing reoperation (Figure 1): 0-3 months prior, AOR 1.536 (95% CI: 1.201 -1.965); 3-6 months, AOR 1.843 (95% CI: 1.362-2.494); and 6-12 months AOR 1.339 (95% CI: 0.914 -1.962). Of those patients that underwent a reoperation, the most common surgery performed was revision rotator cuff repair followed by arthroscopic debridement (48.5% versus 38.9% respectively). Conclusion: Patients who had received a CSI within 6 months prior to RCR were much more likely to undergo a subsequent reoperation within the following 3 years. These odds diminished as more time passed between CSI and primary repair. Consideration should therefore be given to delaying primary rotator cuff repair for 6 months following injection.

‘A good fit?’ Bringing the sociology of footwear to the clinical encounter in podiatry services: a narrative review
Authors: Nicholls Emily , Robinson Victoria , Farndon Lisa , Vernon Wesley 
Published: March 2018

AbstractBackgroundThis narrative review explores the ways in which drawing on theories and methods used in sociological work on footwear and identity can contribute to healthcare research with podiatrists and their patients, highlighting recent research in this field, implications for practice and potential areas for future development.Traditionally, research within Podiatry Services has tended to adopt a quantitative, positivist focus, developing separately from a growing body of sociological work exploring the importance of shoes in constructing identity and self‐image. Bringing qualitative research drawing on sociological theory and methods to the clinical encounter has real potential to increase our understanding of patient values, motivations and – crucially – any barriers to adopting ‘healthier’ footwear that they may encounter. Such work can help practitioners to understand why patients may resist making changes to their footwear practices, and help us to devise new ways for practitioners to explore and ultimately break down individual barriers to change (including their own preconceptions as practitioners). This, in turn, may lead to long‐term, sustainable changes to footwear practices and improvements in foot health for those with complex health conditions and the wider population.ConclusionA recognition of the complex links between shoes and identity is opening up space for discussion of patient resistance to footwear changes, and paving the way for future research in this field beyond the temporary ‘moment’ of the clinical encounter.

Purpose Mutations in the mitochondrial enzyme succinate dehydrogenase (SDH) subunit genes are associated with a wide spectrum of tumors, including pheochromocytomas and paragangliomas, GI stromal tumors, renal cell carcinomas, and pituitary adenomas. SDH-related tumorigenesis is believed to be secondary to accumulation of the oncometabolite succinate. Our aim was to investigate the potential clinical applications of proton-1 magnetic resonance spectroscopy (1H-MRS) in a range of suspected SDH-related tumors. Patients and Methods Fifteen patients were recruited to this study. Respiratory-gated single-voxel 1H-MRS was performed at 3T to quantify the content of succinate at 2.4 ppm and choline at 3.22 ppm. Results A succinate peak was seen in six patients, all of whom had germ line SDHx mutations or loss of SDHB by immunohistochemistry. Succinate peaks were also detected in two patients with metastatic wild-type GI stromal tumors and no detectable germ line SDHx mutations but with somatic epimutations in SDHC. Three patients without tumor succinate peaks retained SDHB expression, consistent with SDH functionality. In six patients with borderline or absent peaks, technical difficulties such as motion artifact rendered 1H-MRS difficult to interpret. Sequential imaging in a patient with a metastatic abdominal paraganglioma demonstrated loss of the succinate peak after four cycles of [177Lu]DOTATATE, with a corresponding biochemical response in normetanephrine. Conclusion This study has demonstrated the translation into clinical practice of in vivo metabolomic analysis using 1H-MRS in patients with SDH-deficient tumors. Potential applications include noninvasive diagnosis and disease stratification, as well as monitoring of tumor response to targeted treatments.
