Achieving an 80% Carbon Free Electricity System in China by 2035. iScience 2022; 25:105180. [PMID: 36217546 PMCID: PMC9547298 DOI: 10.1016/j.isci.2022.105180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 08/08/2022] [Accepted: 09/19/2022] [Indexed: 11/23/2022] Open
Abstract
Dramatic reductions in solar, wind, and battery storage costs create new opportunities to reduce emissions and costs in China’s electricity sector, beyond current policy goals. This study examines the cost, reliability, emissions, public health, and employment implications of increasing the share of non-fossil fuel (“carbon free”) electricity generation in China to 80% by 2035. The analysis uses state-of-the-art modeling with high resolution load, wind, and solar inputs. The study finds that achieving an 80% carbon-free electricity system in China by 2035 could reduce wholesale electricity costs, relative to a current policy baseline, while maintaining high levels of reliability, reducing deaths from air pollution, and increasing employment. In our 80% scenario, wind and solar generation capacity reach 3 TW and battery storage capacity reaches 0.4 TW by 2035, implying a rapid scale up in these resources that will require changes in policy targets, markets and regulation, and land use policies. China could reach 80% carbon-free electricity by 2035 at 6% lower cost China’s power grids can be reliably operated with a high level of non-fossil generation Exceeding existing non-fossil goals can reduce additional emission and health impacts Job gains in clean energy more than offset those lost in coal-related industries

Top 100 #PCOS influencers: Understanding who, why and how online content for PCOS is influenced. Front Endocrinol (Lausanne) 2022; 13:1084047. [PMID: 36568090 PMCID: PMC9768020 DOI: 10.3389/fendo.2022.1084047] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 11/23/2022] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND With the exponential increase in digital space of social media platforms, a new group called social media influencers are driving online content of polycystic ovary syndrome (PCOS) which eventually influences behaviour and decision-making process. The objective of this study was to identify the top 100 social media (Twitter) influencers and organizations from across the globe who are advocating for PCOS. We further explored the origin and journey of these social media influencers. METHODS We identified the top 100 PCOS influencers and organizations between July and August 2022 using three social network analysis tools- Cronycle, Symplur and SocioViz. These influencers were invited to a semi-structured interview to explore why they chose to become an influencer and the support they have to deliver their online content. Two independent authors coded the anonymised transcripts from these interviews and broad themes were identified by thematic inductive analysis. RESULTS 95.0% of individual influencers and 80% of organisations are from high-income countries. Most influencers in our study agree that social media is an essential tool in the present day to raise awareness of PCOS. However, they reiterated social media also has significant disadvantages that require consideration and caution. Most influencers were driven by poor personal experience and worked voluntarily to reduce misinformation and improve the experiences of women diagnosed with PCOS in the future. Although there is an interest in working together, there is currently minimal collaborative work between influencers. CONCLUSION There is a global inequity of #PCOS influencers online. Establishing standards and support based on evidence may help develop more influencers, especially in low- and middle-income countries, so we can counter misinformation and provide locally acceptable guidance.

Observing the use of knee arthroplasty appropriateness tools in clinical practice: do appropriateness criteria tools predict surgeon decision-making? Osteoarthritis Cartilage 2021; 29:1275-1281. [PMID: 34217825 DOI: 10.1016/j.joca.2021.06.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2021] [Revised: 06/09/2021] [Accepted: 06/22/2021] [Indexed: 02/02/2023]
Abstract
OBJECTIVE The primary aim of this study was to evaluate the agreement between surgeons and two validated total knee arthroplasty (TKA) appropriateness tools, and secondarily to compare Australian appropriateness rates to those reported internationally. METHODS A consecutive sample of patients from one public hospital arthroplasty clinic and a convenience sample from private rooms of surgeons in New South Wales, Australia (n = 11), referred for surgical opinion regarding TKA were enrolled over 1 year. Surgeons applied appropriateness tools created by Escobar et al. and the American Academy of Orthopaedic Surgeons (AAOS). Correlation between the appropriateness tools and surgeon's decisions were evaluated. RESULTS There were 368 patients enrolled, and contrasting rates of being "appropriate" for surgery were identified between the Escobar (n = 109, 29.6%) and AAOS (n = 292, 79.3%) tools. Surgeon agreement with the Escobar tool was substantial (ĸ = 0.61, 95%CI: 0.53-0.69) compared to slight with the AAOS tool (ĸ = 0.11, 95%CI: 0.06-0.16). Of those advised against TKA (n = 179, 48.6%), the AAOS tool suggested many patients (n = 111, 62.0%) were "appropriate" compared to the Escobar tool (n = 12, 6.7%). CONCLUSIONS Surgeons rated patients seeking opinion for TKA as appropriate over half the time, however the AAOS tool had low correlation with surgeons as opposed to the Escobar tool. This was illustrated by both tools rating a majority of patients to be operated on as appropriate, but only the AAOS tool considering most patients not chosen for surgery to be appropriate. When comparing previously published appropriateness rates, appropriateness in Australia, USA, Spain and Qatar was found to be similar.

Abstract
Amylase is elevated in the foregut and has been used to confirm anastomotic integrity after pancreatic surgery. The physiological activity of pancreatic enzymes in the ileum has been studied in healthy volunteers but not quantitated with the simple and readily available amylase measurements employed with serum tests. We aim to quantitate the levels of amylase in the terminal ileum. This was a prospective, non-randomised, non-blinded, consecutive cohort study conducted at the Royal Brisbane and Women's Hospital. Consecutive patients undergoing routine surgery with an ileostomy were invited to participate in the study. Ileostomy effluent was collected and analysed daily for the first 5 post-operative days. This validation cohort included 8 males and 3 females, with a mean age of 49 years. Median daily amylase levels ranged from 4470 U/L to 23,000 U/L, with no specimens falling within the laboratory serum reference range of 40 to 130 U/L. Two specimens were not available on day one post-operative due to complete ileus. The sample size of 11 patients is small but was considered sufficient given that 55 effluent specimens were anticipated for analysis. Amylase levels remain highly elevated as the enzyme transits through the length of the small intestine and measured in the terminal ileum, and can be readily quantitated by the existing testing methodology routinely available.

Anastomotic leak does not affect long-term and longitudinal functional outcomes after ileal pouch surgery for ulcerative colitis when managed aggressively. Tech Coloproctol 2020; 24:1285-1292. [PMID: 32856185 DOI: 10.1007/s10151-020-02331-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 08/13/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND Ileal pouch-anal anastomosis (IPAA) is an effective surgical alternative to a permanent ileostomy following proctocolectomy in patients with ulcerative colitis (UC). Anastomotic leakage (AL) is a serious postoperative complication of an intestinal anastomosis that is associated with increased morbidity and mortality. The aim of this study was to evaluate the longitudinal long-term functional outcomes of patients who had IPAA that was complicated by AL. METHODS A retrospective longitudinal cohort study was performed of patients who had an IPAA procedure at a tertiary referral centre and a metropolitan private centre in Australia, over a 14-year period (October 2003-October 2017). The long-term functional outcome was assessed using objective clinical measures such as the number of bowel motions during the day and overnight, ability to defer defaecation and the presence of faecal incontinence, and repeated at annual intervals. RESULTS A total of 138 patients [mean age 38.5 (± 16.9) years, 72 males] satisfied the inclusion criteria. AL was diagnosed in 14 (10%) patients [mean age 38.8 (± 17) years, 10 males], 11 (79%) of which were managed with surgery. The median bowel motion frequency during the day and overnight remained stable over a median of 62 (28-91) months follow-up, with no significant difference between those who had AL or not (p = 0.6, p = 0.1 respectively). The incidence of faecal incontinence remained low, and the majority of patients in both groups were able to defer defaecation for more than 60 min. Six patients (4.3%) had their pouch excised. CONCLUSIONS There is no statistical difference in longitudinal function between patients who experienced AL after IPAA surgery for UC compared with those who did not. Therefore, an acute AL does not negatively impact long-term functional outcomes in IPAA patients.

Abstract
BACKGROUND Tumour extension beyond the mesorectal plane (ymrT4) occurs in 5-10 per cent of patients with rectal cancer and 10 per cent of patients develop locally recurrent rectal cancer (LRRC) after primary surgery. There is global variation in healthcare delivery for these conditions. METHODS An international benchmark trial of the management of ymrT4 tumours and LRRC was undertaken in France and Australia between 2015 and 2017. Heterogeneity in management and operative decision-making were analysed by comparison of surgical resection rates, blinded intercountry reading of pelvic MRI, quality-of-life assessment and qualitative evaluations. RESULTS Among 154 patients (97 in France and 57 in Australia), 31·8 per cent had ymrT4 disease and 68·2 per cent LRRC. The surgical resection rates were 88 and 79 per cent in France and Australia respectively (P = 0·112). The concordance in operative planning was low (κ = 0·314); the rate of pelvic exenteration was lower in France than Australia both in clinical practice (36 of 78 versus 34 of 40; P < 0·001) and in theoretical conditions (10 of 25 versus 50 of 57; P = 0·002). The R0 resection rate was lower in France than Australia for LRRC (25 of 49 versus 18 of 21; P = 0·007) but not for ymrT4 tumours (21 of 26 versus 15 of 15; P = 0·139). Morbidity rates were similar. Patients who underwent non-exenterative procedures had higher scores on the mental functioning subscale at 12 months (P = 0·047), and a lower level of distress at 6 months (P = 0·049). Qualitative analysis highlighted five categories of psychosocial factors influencing treatment decisions: patient, strategy, specialist, organization and culture. CONCLUSION This international benchmark trial has highlighted the differences in worldwide treatment of locally advanced and LRRC. Standardized care should improve outcomes for these patients.

Abstract
Abstract
Objective
This study provides normative data on the SCAT5 Cognitive Screening, establishes test-retest reliability, and creates clinically relevant cut points for low performance.
Method
The multisport baseline sample was composed of 727 uninjured college athletes (52% female) at a Division I university who were administered the SCAT5 before the 2017–2018 season. Descriptive statistics, including base rates of low performance, were calculated for SCAT5 indices. Repeat baseline testing was completed by 325 athletes (48% female) at 1 year (days M = 352.56;SD = 56.03) who were included in the test-retest reliability and practice effect analyses. Reliable change indices were calculated.
Results
Descriptive statistics for SCAT5 were computed for both baselines (Baseline 1: SAC total M = 35.15,SD = 4.93; immediate recall total M = 20.01,SD = 3.46; delayed recall total M = 6.43,SD = 1.75). A difference in descriptive statistics and practice effects by sex on the SCAT5 Cognitive Screening has been demonstrated (Bailey, Meyer, Tangen et al., under review). For female athletes, the 1st administration cutoff scores for abnormal performance (<10th%ile) included SAC total score = 33, immediate recall score = 18, and delayed recall score = 6. For male athletes, the 1st administration cutoff scores for abnormal performance (<10th%ile) included SAC total score = 30, immediate recall score = 17, and delayed recall score = 5. Test-retest reliability of the SAC was similar to previous versions but varied by sex. Reliable change indices (RCI) were created with cut points for significant change.
Conclusions
The present study provides clinically relevant normative data for the SCAT5 Cognitive Screening. Cut points for low performance on both reliable chance indices (RCIs) and normative performance reflected meaningful sex differences that could influence clinical interpretation.

Abstract
BACKGROUND Technological developments have allowed advances in minimally invasive techniques for total mesorectal excision such as laparoscopy, robotics, and transanal surgery. There remains an ongoing debate about the safety, benefits, and appropriate clinical scenarios for which each technique is employed. The aim of this study was to provide a panel of expert opinion on the role of each surgical technique currently available in the management of rectal cancer using a modified Delphi method. METHODS Surveys were designed to explore the key patient- and tumor-related factors including clinical scenarios for determining a surgeon's choice of surgical technique. RESULTS Open surgery was favoured in obese patients with an extra-peritoneal tumor and a positive circumferential resection margin (CRM) or T4 tumor when a restorative resection was planned. Laparoscopy was favoured in non-obese males and females, in both intra- and extra-peritoneal tumors with a clear CRM. Robotic surgery was most commonly offered to obese patients when the CRM was clear and if an abdominoperineal resection was planned. Transanal total mesorectal excision (taTME) was preferred in male patients with a mid or low rectal cancer, particularly when obese. Transanal endoscopic microsurgery/transanal minimally invasive surgery local excision was only offered to frail patients with small, early stage tumors. CONCLUSIONS All surgical techniques for rectal cancer dissection have a role and may be considered appropriate. Some techniques have advantages over others in certain clinical situations, and the best outcomes may be achieved by considering all options before applying an individualised approach to each clinical situation.

Abstract
AIM We studied the levels of amylase in drain fluid to investigate its utility as a biomarker of anastomotic leak in ileal pouch patients who did not have a covering loop ileostomy. The luminal contents of the small intestine are high in amylase. Ileal J pouches are formed for restoration of continuity in patients with ulcerative colitis after removal of the colon and rectum. A drain is placed alongside the ileal pouch in the pelvis. METHOD This study is a retrospective analysis of prospectively collected daily drain fluid amylase levels in consecutive patients undergoing restorative proctectomy and ileal J pouch anal anastomosis, without a covering loop ileostomy, between November 2016 and April 2018. RESULTS Thirteen patients underwent surgery without a covering loop ileostomy. Two patients suffered an anastomotic leak and were returned to theatre, one on day 5 and the other on day 6 postoperatively. The mean daily drain fluid amylase level in those who did not leak was between 25 and 46 U/l with a range of 22-139 U/l for all samples collected. In the two patients who suffered a clinical leak the drain fluid amylase level rose to 22 432 and 10 212 U/l on the day of clinical leak diagnosis. The mean rectal tube (intraluminal) amylase level was 63 097 U/l as measured on day 1 postoperatively. CONCLUSION In this small cohort of patients, the measurement of drain fluid amylase is a highly sensitive biomarker of clinical anastomotic leak.

Abstract
Background: Early cancer diagnosis is a critical component of comprehensive cancer control, however more than 50% of head and neck cancers (HNCs) are diagnosed at advanced stage. HNC patients from regional/remote areas are less likely to use radiotherapy during treatment and have poorer survival outcomes than metropolitan patients. Aim: The aim of this study was to examine pathways to treatment of patients with HNC in New South Wales (NSW) and associations between duration of components of the pathway with survival. Methods: Patients diagnosed with squamous cell carcinoma (SCC) of the oral cavity, oropharynx, or cutaneous SCC from 1st July 2008 to 30th June 2013 were identified from a prospectively maintained database. Data were extracted and supplemented by a retrospective audit of medical records at Royal Prince Alfred Hospital and specialists' records. Results: Two hundred and fifty eligible patients were identified (78% male) with mean (SD) age at diagnosis 64.5 (13.5) years. At diagnosis, 75%, 24% and 1% lived in metropolitan, regional and remote areas of NSW, respectively. Twelve per cent of patients lived > 100 km from a hospital with a HNC multidisciplinary team (median [IQR] 7.5 km [25.1]). More than two-thirds (69%) of tumors were diagnosed as advanced stage, and mean follow-up time was 3.5 years. We will present additional findings quantifying intervals along the pathway to treatment (from symptom onset, first specialist visit, diagnosis and treatment), and the associations with survival, and compare findings to those from a second regional site on the mid north coast of NSW. Conclusion: An increasing proportion of the NSW population resides outside major cities. This study is the first step in understanding patient and health system factors that facilitate and impede early diagnosis of HNC. Findings from this study may be used to develop interventions aimed at improving early HNC diagnosis.

Abstract
The incidence of acute kidney injury (AKI) and its impact on chronic kidney disease (CKD) following pediatric nonkidney solid organ transplantation is unknown. We aimed to determine the incidence of AKI and CKD and examine their relationship among children who received a heart, lung, liver, or multiorgan transplant at the Hospital for Sick Children between 2002 and 2011. AKI was assessed in the first year posttransplant. Among 303 children, perioperative AKI (within the first week) occurred in 67% of children, and AKI after the first week occurred in 36%, with the highest incidence among lung and multiorgan recipients. Twenty-three children (8%) developed CKD after a median follow-up of 3.4 years. Less than 5 children developed end-stage renal disease, all within 65 days posttransplant. Those with 1 AKI episode by 3 months posttransplant had significantly greater risk for developing CKD after adjusting for age, sex, and estimated glomerular filtration rate at transplant (hazard ratio: 2.77, 95% confidence interval, 1.13-6.80, P trend = .008). AKI is common in the first year posttransplant and associated with significantly greater risk of developing CKD. Close monitoring for kidney disease may allow for earlier implementation of kidney-sparing strategies to decrease risk for progression to CKD.

Abstract
The discovery of a novel, selective and fully efficacious CB2 agonist with satisfactory pharmacokinetic and pharmaceutical properties is described. Compound 6 was efficacious in a rat model of osteoarthritis pain following oral administration and, in contrast to morphine, maintained its analgesic effect throughout a 5-day subchronic treatment paradigm. These data were consistent with our hypothesis that full agonist efficacy is required for efficient internalization and recycling of the CB2 receptor to avoid tachyphylaxis. Based on its overall favorable preclinical profile, 6 (APD371) was selected for further development for the treatment of pain.

Abstract
OBJECTIVES To determine pregnancy risk and receptiveness to emergency department (ED)-based pregnancy prevention interventions among adolescents accessing care in the ED. STUDY DESIGN Cross-sectional electronic survey of adolescent females in a pediatric ED used to calculate the Pregnancy Risk Index, a validated measure estimating the annual risk of becoming pregnant based on recent sexual activity, contraceptive method(s), method-specific contraceptive failure rates, and interest in receipt of ED-based contraceptive services. RESULTS Of 229 participants, 219 were not pregnant, and 129 reported sexual experience. Overall, 72.4% (n = 166) endorsed negative pregnancy intentions. The overall Pregnancy Risk Index for the 219 nonpregnant participants was 9.6 (95% CI 6.8-12.4), and was 17.5 (95% CI 12.8-22.2) for the 129 sexually experienced participants. A Pregnancy Risk Index greater than the national average of 5 was associated with older age (aOR 3.0; 95% CI 1.5-5.85), nonprivate insurance (aOR 7.1; 95% CI 1.6-32.1), prior pregnancy (aOR 2.7; 95% CI 1.2-6.0), and chief complaint potentially related to a reproductive health concern (aOR 2.6; 95% CI 1.4-5.1). In this cohort, 85.1% (n = 194) believed that the ED should provide information about pregnancy prevention, the majority of whom (64.9%; n = 148) believed that pregnancy prevention services should be offered at all ED visits. CONCLUSION This study demonstrates a high unintended pregnancy risk among adolescents accessing care in the ED. Adolescents report interest in receiving pregnancy prevention information and services in the ED, regardless of reason for visit. Strategies to incorporate successfully the provision of reproductive health services into ED care should be explored.

Abstract
The Mental Health Commission of Canada defines peer support as "a supportive relationship between people who have a lived experience in common … in relation to a mental health challenge or illness … related to their own mental health or that of a loved one" (Sunderland et al. 2013: 11). In Ontario, a key resource for peer support is the Ontario Peer Development Initiative (OPDI), which is an umbrella organization of mental health Consumer/Survivor Initiatives (CSIs) and peer support organizations across the province of Ontario. Member organizations are run by and for people with lived experience of a mental health or addiction issue and provide a wide range of services and activities within their communities. The central tenet of member organizations is the common understanding that people can and do recover with the proper supports in place and that peer support is integral to successful recovery. Nationally, Peer Support Accreditation and Certification Canada has recently been established. The relatively new national organization focuses on training and accrediting peer support workers. This paper focuses on a range of diverse peer support groups and CSIs that operate in London and surrounding areas.

Abstract
OBJECTIVE To detail the presentation of calcium pyrophosphate deposition disease (CPPD) in the ankle joint. The aim of this case report is to inform health-care practitioners about the presentation of this condition in an uncommon location and discuss the diagnosis, potential treatment, and management strategies for a patient with CPPD. CLINICAL FEATURES A 36-year-old male patient presented to a chiropractic clinic with an acute, painful, and swollen ankle, which was later diagnosed by plain film radiograph as CPPD. A rheumatology follow-up was recommended and at-home treatment was prescribed to treat acute symptoms and monitor progress. OUTCOME No chiropractic treatment was provided and the patient has been referred to a rheumatologist for further assessment. The diagnosis of CPPD was confirmed and he was advised to take an anti-inflammatory if symptoms recurred and booked for further follow-up in six months. SUMMARY Although the presentation is less common, CPPD can present in the ankle joint and mimic other inflammatory disorders. Conservative treatment can be applied to treat acute symptoms and referral to a rheumatologist is suggested to monitor progress of this condition.

Abstract
Aims The pelvis rotates in the sagittal plane during daily activities. These rotations have a direct effect on the functional orientation of the acetabulum. The aim of this study was to quantify changes in pelvic tilt between different functional positions. Patients and Methods Pre-operatively, pelvic tilt was measured in 1517 patients undergoing total hip arthroplasty (THA) in three functional positions – supine, standing and flexed seated (the moment when patients initiate rising from a seated position). Supine pelvic tilt was measured from CT scans, standing and flexed seated pelvic tilts were measured from standardised lateral radiographs. Anterior pelvic tilt was assigned a positive value. Results The mean pelvic tilt was 4.2° (-20.5° to 24.5°), -1.3° (-30.2° to 27.9°) and 0.6° (-42.0° to 41.3°) in the three positions, respectively. The mean sagittal pelvic rotation from supine to standing was -5.5° (-21.8° to 8.4°), from supine to flexed seated was -3.7° (-48.3° to 38.6°) and from standing to flexed seated was 1.8° (-51.8° to 39.5°). In 259 patients (17%), the extent of sagittal pelvic rotation could lead to functional malorientation of the acetabular component. Factoring in an intra-operative delivery error of ± 5° extends this risk to 51% of patients. Conclusion Planning and measurement of the intended position of the acetabular component in the supine position may fail to predict clinically significant changes in its orientation during functional activities, as a consequence of individual pelvic kinematics. Optimal orientation is patient-specific and requires an evaluation of functional pelvic tilt pre-operatively. Cite this article: Bone Joint J 2017;99-B:184–91.

The adaptation of health care marketing to the digital era. J Med Life 2017; 10:44-46.

Abstract
The purpose of health care marketing is to learn and understand the needs and desires of prospective patients in order to be able to meet those necessities at the highest standards. A big advantage is the targeting capability of the electronic media that has led to its being used by managers of marketing in medical institutions as means of advertisement when they develop the marketing strategies. Regarding social media, it is safe to say that there are communication platforms that can promote certain behaviours thus influencing decision-making. Through social media, people stay in touch with other people and they can provide a mean for medical institutions to permanently communicate with the existing patients or with the potential ones. In addition, social media can be used in advertising and promoting strategies, by posting information about discounts, offers and advantages of accessing the products provided by a certain institution. A study was conducted on 126 patients of a dental clinic in Bucharest. 126 new patients were selected on a period of 22 months from January 2015 until October 2016. The patients never had any treatment in this clinic and were influenced by the Internet to seek for dental care services. The purpose of this study was to evaluate the digital methods of promoting medical services, bringing new patients to a clinic. The results of the study demonstrated the need for digital methods of promoting medical care services in order to expand a business. A strategic way of thinking in this case implied attracting new patients and offering them quality health care services, which ensured their satisfaction and the probability of their recommending the health facility further. This study revealed an important role of social networking sites in promoting. This high response was probably responsible due to targeted promoting services. Almost all the new patients who completed the form will remain patients of this clinic in future.

Impact of schizophrenia on anterior and posterior hippocampus during memory for complex scenes. NEUROIMAGE-CLINICAL 2016; 13:82-88. [PMID: 27942450 PMCID: PMC5133646 DOI: 10.1016/j.nicl.2016.11.017] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/08/2016] [Revised: 11/15/2016] [Accepted: 11/16/2016] [Indexed: 11/30/2022]
Abstract
Objectives Hippocampal dysfunction has been proposed as a mechanism for memory deficits in schizophrenia. Available evidence suggests that the anterior and posterior hippocampus could be differentially affected. Accordingly, we used fMRI to test the hypothesis that activity in posterior hippocampus is disproportionately reduced in schizophrenia, particularly during spatial memory retrieval. Methods 26 healthy participants and 24 patients with schizophrenia from the UC Davis Early Psychosis Program were studied while fMRI was acquired on a 3 Tesla Siemens scanner. During encoding, participants were oriented to critical items through questions about item features (e.g., “Does the lamp have a square shade?”) or spatial location (e.g., “Is the lamp on the table next to the couch?”). At test, participants determined whether scenes were changed or unchanged. fMRI analyses contrasted activation in a priori regions of interest (ROI) in anterior and posterior hippocampus during correct recognition of item changes and spatial changes. Results As predicted, patients with schizophrenia exhibited reduced activation in the posterior hippocampus during detection of spatial changes but not during detection of item changes. Unexpectedly, patients exhibited increased activation of anterior hippocampus during detection of item changes. Whole brain analyses revealed reduced fronto-parietal and striatal activation in patients for spatial but not for item change trials. Conclusions Results suggest a gradient of hippocampal dysfunction in which posterior hippocampus – which is necessary for processing fine-grained spatial relationships – is underactive, and anterior hippocampus – which may process context more globally - is overactive. Patients with schizophrenia show impaired memory for spatial relationships amongst objects in scenes. Patients have less posterior hippocampal activation during spatial memory and more anterior hippocampal activation during item memory. This gradient of hippocampal dysfunction in schizophrenia, suggests that it should not be examined as a unitary structure in future studies.

Abstract
This article reviews the state of the art of rural health research and evaluation with par ticular emphasis on the questions of access, health personnel, and financing. The current state of knowledge both in the published and in the unpublished literature in each area is summarized and a series of unresolved issues is proposed. A strategy for further research to include the various types of rural health care programs is described. Major findings suggest that, although rural populations do have somewhat less access to care than do urban populations, our ability to quantify precisely the extent and importance of this discrepancy is underdeveloped. Despite a substantial investment in a variety of rural health care programs there is inadequate information as to their effectiveness. Programs designed to increase the supply of health personnel to rural areas have met with mixed success. Sites staffed by National Health Service Corps personnel show consistently lower productivity than do sites under other sponsorship. Nonphysician personnel (physician assistants and nurse practitioners) offer apromising source of primary carefor rural areas; recent legislation that reimburses such care should increase their utilization. A persistent problem is the expectation (often a mandate) incorporated into many rural health care demonstration efforts that the programs become financially self-sufficient in a finite period of time. Self-sufficiency is a function of utilization, productivity, and the ability to recover charges for services. In many instances stringent enforcement of the self-suf ficiency requirement may mean those those who need the services most will be least likely to receive them.

Abstract
The development of DSM-III through DSM-5 has relied heavily on expert consensus. In this essay, we provide an historical and critical perspective on this process. Over the last 40 years, medicine has struggled to find appropriate methods for summarizing research results and making clinical recommendations. When such recommendations are issued by authorized organizations, they can have widespread influence (i.e. DSM-III and its successors). In the 1970s, expert consensus conferences, led by the NIH, reviewed research about controversial medical issues and successfully disseminated results. However, these consensus conferences struggled with aggregating the complex available evidence. In the 1990s, the rise of evidence-based medicine cast doubt on the reliability of expert consensus. Since then, medicine has increasingly relied on systematic reviews, as developed by the evidence-based medicine movement, and advocated for their early incorporation in expert consensus efforts. With the partial exception of DSM-IV, such systematic evidence-based reviews have not been consistently integrated into the development of the DSMs, leaving their development out of step with the larger medical field. Like the recommendations made for the NIH consensus conferences, we argue that the DSM process should be modified to require systematic evidence-based reviews before Work Groups make their assessments. Our suggestions - which would require leadership and additional resources to set standards for appropriate evidence hierarchies, carry out systematic reviews, and upgrade the group process - should improve the objectivity of the DSM, increase the validity of its results, and improve the reception of any changes in nosology.

Abstract
BACKGROUND For people with mental illness (psychiatric survivors), seeking and securing employment involves personal, social, and environmental factors. In Canada, psychiatric survivors are under-represented in the workforce, and services can help by tailoring their supports to help make the most gains in employment. OBJECTIVE Determine whether individual socio-demographic and health factors predict seeking and securing employment among psychiatric survivors. METHODS A community sample of psychiatric survivors from a Southwestern Ontario region participated in this study. Stepwise logistic regression was used to analyze data from 363 participants who had completed a variety of questionnaires to ascertain individual characteristics and employment outcomes. RESULTS Health service utilization, living circumstances, homelessness, substance use issues, general health, social integration, ethnicity, having children under 18, and being a student emerged as significant predictors of seeking and securing work. Other commonly accepted human capital indicators, such as education and age, were not predictive of employment search behavior and outcomes. CONCLUSIONS Individual characteristics that predict employment search and success outcomes for psychiatric survivors include aspects related to treatment and living circumstances, which stands in contrast to predictors of employment for the general population, suggesting that employment support services may need to be tailored to psychiatric survivors specifically.

Abstract
AIM The surgical management of locally recurrent rectal cancer (LRRC) has become widely accepted to afford cure and improve quality of life in this subset of patients. Thus far, traditional surgical and oncological markers have been used to highlight the success of surgical intervention. The use of patient-reported outcomes, specifically health-related quality of life (HRQoL), is sparse in these patients. This may be in part due to the lack of well-designed, validated instruments. This study identifies HRQoL issues relevant to patients undergoing surgery for LRRC, with the aim of developing a conceptual framework of HRQoL specific to LRRC to enable measurement of patient-reported outcomes in this cohort of patients. METHOD Qualitative focus groups were undertaken at two institutions to identify relevant HRQoL themes. The principles of thematic content analysis were used to analysis data. NViVo10 was used to analyse data. RESULTS Twenty-one patients participated in six consecutive focus groups. Two patterns of themes emerged related to HRQoL and healthcare service delivery and utilization. Identified themes related to HRQoL included symptoms, sexual function, psychological impact, role and social functioning and future perspective. Under healthcare service and delivery and utilization the subdomain of disease management, treatment expectations and healthcare professionals were identified. CONCLUSION This is the first qualitative study undertaken exclusively in patients with LRRC to ascertain relevant HRQoL outcomes. The impact of LRRC on patients is wide-ranging and extends beyond traditional HRQoL outcomes. The study operationalizes the identified outcomes into a conceptual framework, which will provide the basis for the development of a LRRC-specific patient-reported outcome measure.

Abstract
BACKGROUND Cutaneous leishmaniasis (CL) due to Leishmania major (L. major) is common in the Middle East; however, this skin infection may be under-diagnosed when it presents atypically. OBJECTIVE To highlight the occurrence of uncommon presentations of CL that may elude diagnosis. MATERIALS AND METHODS A retrospective study was performed among patients who presented at The Sheba Medical Center between 2005 and 2014 with atypical clinical presentations of CL due to L. major. RESULTS Twelve patients with unusual clinical presentations of L. major CL were identified. All infections were acquired in L. major - endemic areas of Israel. The average age was 37 years. The average number of lesions was 2. Nine patients presented with a form that mimicked other forms of CL, such as lupoid, giant ulcer, sporotrichoid and recidivans, and three had a variant resembling other infectious skin diseases, such as erysipeloid and verruciform. All patients required systemic therapy. CONCLUSION Cutaneous leishmaniasis due to L. major can masquerade as many other infectious and inflammatory diseases. In addition, it can mimic clinical forms of New World CL. We suggest that in endemic countries or in travellers returning from countries where L. major is endemic, polymerase chain reaction (PCR) for Leishmania-specific DNA should be performed routinely in cases of unusual presentations of dermatitis with a single or a few lesions, even if a diagnosis of CL was not considered by the referring clinician.

Abstract
APD334 was discovered as part of our internal effort to identify potent, centrally available, functional antagonists of the S1P1 receptor for use as next generation therapeutics for treating multiple sclerosis (MS) and other autoimmune diseases. APD334 is a potent functional antagonist of S1P1 and has a favorable PK/PD profile, producing robust lymphocyte lowering at relatively low plasma concentrations in several preclinical species. This new agent was efficacious in a mouse experimental autoimmune encephalomyelitis (EAE) model of MS and a rat collagen induced arthritis (CIA) model and was found to have appreciable central exposure.

Abstract
BACKGROUND Onchocerciasis is an infectious disease caused by the filaria Onchocerca volvulus. Very little is known regarding onchocerciasis imported from endemic to nonendemic areas. OBJECTIVES To evaluate pruritic dermatitis simulating atopic dermatitis in Ethiopian immigrants in Israel. PATIENTS AND METHODS A retrospective study of 27 Ethiopian immigrants to Israel was conducted. Demographics and clinical and laboratory data were collected. RESULTS Of the group of 27 patients, 10 (37%) were men and 17 (63%) were women. The average age at referral was 29 years. All of the patients emigrated from Kuwara, Ethiopia. Diagnosis was done by either positive skin snip test or immunoglobulin (Ig) G4 serology of onchocerciasis in 14 patients. The most common presentation was a combination of lichenified onchodermatitis with atrophy and depigmentation (36%). Eosinophilia and elevated IgE levels were common. Seventeen patients were treated with a single administration of oral ivermectin 200 μg mg(-1). Thirteen patients responded to the treatment. CONCLUSIONS Immigrants from endemic regions to developed countries presenting with pruritic diseases, especially those with a clinical picture suggestive of atopic dermatitis, should be evaluated for possible onchocerciasis infection. Ivermectin, a relatively safe and low-cost treatment, should be considered even in the absence of a proven disease. Physicians should have a high index of suspicion in patients with the corresponding residential history.

Abstract
AIM The decision to create a stoma after anterior resection has significant consequences. Decisions under uncertainty are made with a variety of cognitive tools, or heuristics. Past experience has been shown to be a powerful heuristic in other domains. Our aim was to identify whether the misfortune of recent anastomotic leakage or surgeon propensity to take everyday risks would affect their decision to defunction a range of anastomoses. METHOD Questionnaires were sent to members of the Colorectal Surgical Society of Australia and New Zealand. Participants were asked for demographic information, questions regarding risk-taking propensity, when their last anastomotic leakage occurred and whether they would defunction a range of hypothetical rectal anastomoses grouped according to height, American Society of Anesthesiologists grade and use of preoperative radiotherapy. Scores were derived for hypothetical patient likelihood of having a stoma created and individual surgeon propensity for stoma formation. Hazard regression analysis was used to assess demographic predictors of stoma formation. RESULTS In total, 110 (75.3%) of 146 surveyed surgeons replied; 72 (65.5%) reported anastomotic leakage within the last 12 months. Surgeons' propensity for risk-taking was comparable (24.6 vs 27.53, 95% confidence interval, Mann-Whitney-U) to previously studied participants in economic models. Surgeon age (< 50 years) and lower propensity for risk-taking were demonstrated to be independent predictors of stoma formation on regression analysis. CONCLUSION Although the decision to create a stoma after anterior resection may be made in the belief that its foundation derives from rational thought, it appears that other unrecognized operator factors such as age and risk-taking exert an effect.

Abstract
Purpose: Management of the ICBN during axillary dissection is controversial and the division of ICBN is often trivialised.The effect of dividing the ICBN, and its association with sensory disturbance, is unclear. A systemic review and meta-analysis was performed to evaluate the effect of preserving the ICBN during axillary dissection.
Methods: A systemic literature review and meta-analysis was performed according to the PRISMA and Cochrane Collaboration guidelines. Two authors (SW and SH) independently searched Medline, Pubmed, Embase, Cochrane Database of Systemic Reviews and the Cochrane Controlled Trials Register from 1950 to December 2012 for studies comparing preservation or division of the ICBN in axillary dissection for breast cancer. The primary outcome of this meta-analysis was sensory disturbance, defined as objectively assessed change in sensation in the distribution of the ICBN after axillary dissection. The nature of sensory disturbance was assessed as a secondary outcome, categorised into two types: “hypersensitivity” and “hyposensitivity”.
Results: Three RCTs and four non-RCTs were reviewed. A meta-analysis demonstrated that the incidence of sensory disturbance was significantly lower with preservation of ICBN compared to division of the ICBN with Mantel-Haenzel combined odds ratio 0.31 (0.17-0.57, 95% CI). There was relatively low level of heterogeneity (I2 = 19%, c2 = 2.48, df = 2).
The sensory disturbance was more likely to be hyposensitivity when compared to hypersensitivity (p <0.0001). No difference on number of lymph nodes dissected or operating time was noted.
Conclusion: This meta-analysis demonstrates that division of the ICBN is associated with higher risk of sensory disturbance, and that the nature of this sensory disturbance is more likely to be hyposensitivity, attributable to reduced nerve function.

Abstract
Cognitive abilities are impaired in neurodevelopmental disorders, including autism spectrum disorder (ASD) and schizophrenia. Preclinical models with strong endophenotypes relevant to cognitive dysfunctions offer a valuable resource for therapeutic development. However, improved assays to test higher order cognition are needed. We employed touchscreen technology to design a complex transitive inference (TI) assay that requires cognitive flexibility and relational learning. C57BL/6J (B6) mice with good cognitive skills and BTBR T+tf/J (BTBR), a model of ASD with cognitive deficits, were evaluated in simple and complex touchscreen assays. Both B6 and BTBR acquired visual discrimination and reversal. BTBR displayed deficits on components of TI, when 4 stimuli pairs were interspersed, which required flexible integrated knowledge. BTBR displayed impairment on the A > E inference, analogous to the A > E deficit in ASD. B6 and BTBR mice both reached criterion on the B > D comparison, unlike the B > D impairment in schizophrenia. These results demonstrate that mice are capable of complex discriminations and higher order tasks using methods and equipment paralleling those used in humans. Our discovery that a mouse model of ASD displays a TI deficit similar to humans with ASD supports the use of the touchscreen technology for complex cognitive tasks in mouse models of neurodevelopmental disorders.

Abstract
This prospective interventional study investigated the impact of a three-month, ambulatory HA or HB, semi-individualized, PT-prescribed exercise program following pediatric HTx or LTx. SMW distance, strength, and flexibility were assessed at start and completion of the program and one yr after enrollment. Subjects received either an HB or HA exercise program three times per week. The cohort demonstrated clinically and statistically significant improvements in SMW distances at three months (425.7 ± 109.4-500.6 ± 93.6 m, p < 0.001) and at one yr (528.5 ± 66.6 m, p = 0.001), although there was no difference between the two groups at any time. Similar improvements were also observed in strength and flexibility measures. Correlates with higher SMW distance at three months and one yr included older age, male gender, and underlying diagnosis other than CHD. Male gender and diagnosis other than CHD were associated with a slower improvement in the SMW distance. This is the first report of institutionally based, outpatient exercise rehabilitation in the recovery following pediatric thoracic transplantation. We found similar improvements to HB interventions up to one yr after surgery. Further study of the role of exercise rehabilitation and long-term fitness outcomes is needed.

Abstract
BACKGROUND AND AIMS Airway evaluation following infant cardiac surgery often reveals evidence of tracheobronchial narrowing. We studied the association between airway narrowing and extubation failure (EF) in this population. METHODS Prospective cohort study of infants (age ≤6 months) from March-September 2009. Flexible bronchoscopy (FB) evaluations were obtained using a standardised protocol after operative intervention. The primary endpoint was the development of extubation failure (EF; defined as the need for invasive mechanical ventilation ≤48 h after primary extubation) and several secondary endpoints. RESULTS Fifty-three patients were evaluated at a median age of 81 [interquartile range (IQR) 13-164] days and weight of 4.2 (IQR 3.2-6.0) kg; 13 (25 %) of the patients had single ventricle palliations and two subsequently underwent heart transplantation. Significant airway narrowing was noted in 15 of 30 [50 %, 95 % confidence interval (CI) 31-69 %] patients who underwent FB; ten of the 53 patients (19 %, 95 %CI 10-32 %) subsequently developed EF. Narrowed airway calibre on bronchoscopy had a sensitivity and specificity of 50 % (95 %CI 28-71 %) and 50 % (95 %CI 28-71 %), respectively, for EF. The single greatest predictor of EF by univariate analysis was the need for preoperative ventilation [odds ratio (OR) 6.5, 95 %CI 1.3-33.2, p = 0.03]. Patients with EF had a greater likelihood of intensive care readmission (OR 4.8, 95 %CI 1.1-21, p < 0.04) during the same hospital admission. CONCLUSIONS Airway narrowing on FB is noted frequently after infant cardiac surgery. Overall assessment and presence of narrowing on bronchoscopy had poor sensitivity and specificity for EF in our cohort. Expert assessment of tracheobronchial narrowing on FB has poor to moderate inter-rater reliability.
