RESUMEN
BACKGROUND: Growth hormone (GH)-secreting pituitary adenoma is a severe endocrine disease. Surgery is the currently recommended primary therapy for patients with GH-secreting tumours. However, non-surgical therapy (pharmacological therapy and radiation therapy) may be performed as primary therapy or may improve surgical outcomes. OBJECTIVES: To assess the effects of surgical and non-surgical interventions for primary and salvage treatment of GH-secreting pituitary adenomas in adults. SEARCH METHODS: We searched CENTRAL, MEDLINE, WHO ICTRP, and ClinicalTrials.gov. The date of the last search of all databases was 1 August 2022. We did not apply any language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) and quasi-RCTs of more than 12 weeks' duration, reporting on surgical, pharmacological, radiation, and combination interventions for GH-secreting pituitary adenomas in any healthcare setting. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts for relevance, screened for inclusion, completed data extraction, and performed a risk of bias assessment. We assessed studies for overall certainty of the evidence using GRADE. We estimated treatment effects using random-effects meta-analysis. We expressed results as risk ratios (RR) for dichotomous outcomes together with 95% confidence intervals (CI) or mean differences (MD) for continuous outcomes, or in descriptive format when meta-analysis was not possible. MAIN RESULTS: We included eight RCTs that evaluated 445 adults with GH-secreting pituitary adenomas. Four studies reported that they included participants with macroadenomas, one study included a small number of participants with microadenomas. The remaining studies did not specify tumour subtypes. Studies evaluated surgical therapy alone, pharmacological therapy alone, or combination surgical and pharmacological therapy. Methodological quality varied, with many studies providing insufficient information to compare treatment strategies or accurately judge the risk of bias. We identified two main comparisons, surgery alone versus pharmacological therapy alone, and surgery alone versus pharmacological therapy and surgery combined. Surgical therapy alone versus pharmacological therapy alone Three studies with a total of 164 randomised participants investigated this comparison. Only one study narratively described hyperglycaemia as a disease-related complication. All three studies reported adverse events, yet only one study reported numbers separately for the intervention arms; none of the 11 participants were observed to develop gallbladder stones or sludge on ultrasonography following surgery, while five of 11 participants experienced any biliary problems following pharmacological therapy (RR 0.09, 95% CI 0.01 to 1.47; 1 study, 22 participants; very low-certainty evidence). Health-related quality of life was reported to improve similarly in both intervention arms during follow-up. Surgery alone compared to pharmacological therapy alone may slightly increase the biochemical remission rate from 12 weeks to one year after intervention, but the evidence is very uncertain; 36/78 participants in the surgery-alone group versus 15/66 in the pharmacological therapy group showed biochemical remission. The need for additional surgery or non-surgical therapy for recurrent or persistent disease was described for single study arms only. Surgical therapy alone versus preoperative pharmacological therapy and surgery Five studies with a total of 281 randomised participants provided data for this comparison. Preoperative pharmacological therapy and surgery may have little to no effect on the disease-related complication of a difficult intubation (requiring postponement of surgery) compared to surgery alone, but the evidence is very uncertain (RR 2.00, 95% CI 0.19 to 21.34; 1 study, 98 participants; very low-certainty evidence). Surgery alone may have little to no effect on (transient and persistent) adverse events when compared to preoperative pharmacological therapy and surgery, but again, the evidence is very uncertain (RR 1.23, 95% CI 0.75 to 2.03; 5 studies, 267 participants; very low-certainty evidence). Concerning biochemical remission, surgery alone compared to preoperative pharmacological therapy and surgery may not increase remission rates up until 16 weeks after surgery; 23 of 134 participants in the surgery-alone group versus 51 of 133 in the preoperative pharmacological therapy and surgery group showed biochemical remission. Furthermore, the very low-certainty evidence did not suggest benefit or detriment of preoperative pharmacological therapy and surgery compared to surgery alone for the outcomes 'requiring additional surgery' (RR 0.48, 95% CI 0.05 to 5.06; 1 study, 61 participants; very low-certainty evidence) or 'non-surgical therapy for recurrent or persistent disease' (RR 1.22, 95% CI 0.65 to 2.28; 2 studies, 100 participants; very low-certainty evidence). None of the included studies measured health-related quality of life. None of the eight included studies measured disease recurrence or socioeconomic effects. While three of the eight studies reported no deaths to have occurred, one study mentioned that overall, two participants had died within five years of the start of the study. AUTHORS' CONCLUSIONS: Within the context of GH-secreting pituitary adenomas, patient-relevant outcomes, such as disease-related complications, adverse events and disease recurrence were not, or only sparsely, reported. When reported, we found that surgery may have little or no effect on the outcomes compared to the comparator treatment. The current evidence is limited by the small number of included studies, as well as the unclear risk of bias in most studies. The high uncertainty of evidence significantly limits the applicability of our findings to clinical practice. Detailed reporting on the burden of recurrent disease is an important knowledge gap to be evaluated in future research studies. It is also crucial that future studies in this area are designed to report on outcomes by tumour subtype (that is, macroadenomas versus microadenomas) so that future subgroup analyses can be conducted. More rigorous and larger studies, powered to address these research questions, are required to assess the merits of neoadjuvant pharmacological therapy or first-line pharmacotherapy.

OBJECTIVE: This study examined the perspectives of occupational health providers (OHPs) on the most frequently encountered clinically relevant reasons for employee vaccine hesitancy. METHODS: We conducted an anonymous, online, cross-sectional survey of US OHPs ( N = 217). The survey asked OHPs about the major reasons that employees cite for being unwilling to receive the following three categories of vaccines: COVID-19, annual influenza, and others relevant to the workplace. RESULTS: Concern about adverse effects was the most frequently reported reason for employee vaccine hesitancy for each vaccine category. Mistrust was reported more frequently for COVID-19 than for the influenza vaccine or other vaccines (χ 2P < 0.05). Targets of employee mistrust included government and researchers or scientists, but mistrust of healthcare providers was uncommon. CONCLUSIONS: These results can be used to inform interventions to address vaccine hesitancy in the occupational health setting.

OBJECTIVE: The aim of this study was to determine an optimal follow-up imaging surveillance strategy in terms of cost-effectiveness after resection of nonfunctioning pituitary adenomas with curative intent. METHODS: An individual-level state-transition microsimulation model was used to simulate costs and outcomes associated with three postoperative imaging strategies over a lifetime time horizon: 1) annual MRI surveillance, 2) tapered MRI surveillance (annual surveillance for 5 years followed by surveillance every 2 years), and 3) personalized surveillance (annual surveillance for 5 years followed by surveillance every 2 years when MRI shows remnant disease/postoperative changes, and surveillance at 7, 10, and 15 years for disease-free MRI). Transition probabilities, utilities, and costs were estimated from recent published data and discounted by 3% annually. Model outcomes included lifetime costs (2022 US dollars), quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs). RESULTS: Under base case assumptions, annual surveillance yielded higher costs and lower health effects (QALYs) compared with the tapered and personalized surveillance strategies (dominated). Personalized surveillance demonstrated an additional 0.1 QALY at additional cost ($1298) compared with tapered surveillance (7.7 QALYs at a cost of $12,862). The ICER was $11,793/QALY. The optimal decision was most sensitive to the probability of postoperative changes on MRI after surgery and MRI cost. Accounting for parameter uncertainty, personalized surveillance had a higher probability of being a cost-effective surveillance option compared with the alternative strategies at 79%. CONCLUSIONS: Using standard cost-effectiveness thresholds in the US ($100,000/QALY), personalized surveillance that accounted for remnant disease or postoperative changes on MRI was cost-effective compared with alternative surveillance strategies.

Older adults residing in long-term care facilities (LTCFs) were an at-risk group during the coronavirus disease 2019 (COVID-19) pandemic. Actions to prevent transmission in LTCFs included visitation restrictions, suspension of group activities, and isolating residents in their rooms. Despite these measures, this vulnerable cohort experienced high levels of infection and mortality. The current article reports RNs' and health care assistants' perceptions of the impact of COVID-19 on residents in a LTCF. Using a descriptive qualitative design, semi-structured interviews, which were conducted with seven RNs and four health care assistants, were thematically analyzed. Three themes emerged: Impact on Daily Routine, Disruption to Relationships With Staff, and Vulnerability. Staff perceived residents were negatively impacted physically, emotionally, and socially as a direct consequence of COVID-19 and by strategies introduced to protect them contracting the virus. It is recommended that the long-term impact of the COVID-19 pandemic on this cohort be evaluated from the perspective of all stakeholders (i.e., residents, staff, and families) using a longitudinal research design.

RESUMEN
Poor health at birth can have long-term consequences for children's development. This paper analyses an important factor associated with health at birth: the time of year that the baby is born, and hence seasonal risks they were exposed to in utero. There are multiple potential explanations for seasonality in newborns' health. Most previous research has examined these in isolation. We therefore do not know which explanations are most important - and hence which policy interventions would most effectively reduce the resulting early-life inequalities. In this paper, I use administrative data to estimate and compare the magnitudes of several seasonal risks, seeking to identify the most important drivers of seasonality in the Northern Territory of Australia, a large territory spanning tropical and arid climates and where newborn health varies dramatically with the seasons. I find that the most important explanations are heat exposure and disease prevalence. Seasonality in food prices and road accessibility have smaller effects on some outcomes. Seasonal fertility patterns, rainfall and humidity do not have statistically significant effects. I conclude that interventions that protect pregnant women from seasonal disease and heat exposure would likely improve newborn health in the Northern Territory, with potential long-term benefits for child development. It is likely that similar impacts would apply in other locations with tropical and arid climates, and that, without action, climate change will accentuate these risks.

Mice systemically lacking dipeptidyl peptidase-4 (DPP4) have improved islet health, glucoregulation, and reduced obesity with high-fat diet (HFD) feeding compared to wild-type mice. Some, but not all, of this improvement can be linked to the loss of DPP4 in endothelial cells (ECs), pointing to the contribution of non-EC types. The importance of intra-islet signaling mediated by α to ß cell communication is becoming increasingly clear; thus, our objective was to determine if ß cell DPP4 regulates insulin secretion and glucose tolerance in HFD-fed mice by regulating the local concentrations of insulinotropic peptides. Using ß cell double incretin receptor knockout mice, ß cell- and pancreas-specific Dpp4-/- mice, we reveal that ß cell incretin receptors are necessary for DPP4 inhibitor effects. However, although ß cell DPP4 modestly contributes to high glucose (16.7 mM)-stimulated insulin secretion in isolated islets, it does not regulate whole-body glucose homeostasis.
RESUMEN
Objectives: During the COVID-19 pandemic, healthcare resources including staff were diverted from paediatric services to support COVID-positive adult patients. Hospital visiting restrictions and reductions in face-to-face paediatric care were also enforced. We investigated the impact of service changes during the first wave of the pandemic on children and young people (CYP), to inform recommendations for maintaining their care during future pandemics. Design: A multi-centre service evaluation was performed through a survey of consultant paediatricians working within the North Thames Paediatric Network, a group of paediatric services in London. We investigated six areas: redeployment, visiting restrictions, patient safety, vulnerable children, virtual care and ethical issues. Results: Survey responses were received from 47 paediatricians across six National Health Service Trusts. Children's right to health was largely believed to be compromised by the prioritisation of adults during the pandemic (81%; n = 33). Sub-optimal paediatric care due to redeployment (61%; n = 28) and the impact of visiting restrictions on CYP's mental health (79%; n = 37) were reported. Decreased hospital attendances of CYP were associated with parental fear of COVID-19 infection-risks (96%; n = 45) and government 'stay at home' advice (89%; n = 42). Reductions in face-to-face care were noted to have disadvantaged those with complex needs, disabilities and safeguarding concerns. Conclusion: Consultant paediatricians perceived that paediatric care was compromised during the first wave of the pandemic, resulting in harm to children. This harm must be minimised in subsequent pandemics. Recommendations for future practice which were developed from our findings are provided, including maintaining face-to-face care for vulnerable children.
RESUMEN
Experiences of staff working in residential long-term care facilities (LTCFs) during the coronavirus disease 2019 (COVID-19) pandemic are likely to differ from that of staff working in acute hospitals. The aim of the current study was to describe the experiences of the nursing team supporting frail older adults with high medical and care needs living in a LTCF. Using a descriptive qualitative design, data were gathered via one-to-one semi-structured interviews and thematically analyzed. Four themes emerged: Providing Care During COVID-19, Impact of COVID-19 on Staff, Organizational Management of COVID-19, and Training and Education. Visitation restrictions and staff shortages impacted all aspects of work life. Staff reported increased stress and exhaustion with COVID-19 infection resulting in long-term health issues. It is important to learn from these experiences to inform and empower staff to manage future outbreaks of infectious diseases. [Journal of Gerontological Nursing, 49(3), 40-46.].

Elevated circulating dipeptidyl peptidase-4 (DPP4) is a biomarker for liver disease, but its involvement in gluconeogenesis and metabolic associated fatty liver disease progression remains unclear. Here, we identified that DPP4 in hepatocytes but not TEK receptor tyrosine kinase-positive endothelial cells regulates the local bioactivity of incretin hormones and gluconeogenesis. However, the complete absence of DPP4 (Dpp4-/-) in aged mice with metabolic syndrome accelerates liver fibrosis without altering dyslipidemia and steatosis. Analysis of transcripts from the livers of Dpp4-/- mice displayed enrichment for inflammasome, p53, and senescence programs compared with littermate controls. High-fat, high-cholesterol feeding decreased Dpp4 expression in F4/80+ cells, with only minor changes in immune signaling. Moreover, in a lean mouse model of severe nonalcoholic fatty liver disease, phosphatidylethanolamine N-methyltransferase mice, we observed a 4-fold increase in circulating DPP4, in contrast with previous findings connecting DPP4 release and obesity. Last, we evaluated DPP4 levels in patients with hepatitis C infection with dysglycemia (Homeostatic Model Assessment of Insulin Resistance > 2) who underwent direct antiviral treatment (with/without ribavirin). DPP4 protein levels decreased with viral clearance; DPP4 activity levels were reduced at long-term follow-up in ribavirin-treated patients; but metabolic factors did not improve. These data suggest elevations in DPP4 during hepatitis C infection are not primarily regulated by metabolic disturbances.

CONTEXT: Pituitary tumors are the third most common brain tumor and yet there is no standardization of the surveillance schedule and assessment modalities after transsphenoidal surgery. EVIDENCE ACQUISITION: OVID, EMBASE and the Cochrane Library databases were systematically screened from database inception to March 5, 2020. Inclusion and exclusion criteria were designed to capture studies examining detection of pituitary adenoma recurrence in patients 18 years of age and older following surgical resection with curative intent. EVIDENCE SYNTHESIS: A total of 7936 abstracts were screened, with 812 articles reviewed in full text and 77 meeting inclusion criteria for data extraction. A pooled analysis demonstrated recurrence rates at 1 year, 5 years and 10 years for non-functioning pituitary adenomas (NFPA; N = 3533 participants) were 1%, 17%, and 33%, for prolactin-secreting adenomas (PSPA; N = 1295) were 6%, 21%, and 28%, and for growth-hormone pituitary adenomas (GHPA; N = 1257) were 3%, 8% and 13%, respectively. Rates of recurrence prior to 1 year were 0% for NFPA, 1-2% for PSPA and 0% for GHPA. The mean time to disease recurrence for NFPA, PSPA and GHPA were 4.25, 2.52 and 4.18 years, respectively. CONCLUSIONS: This comprehensive review of the literature quantified the recurrence rates for commonly observed pituitary adenomas after transsphenoidal surgical resection with curative intent. Our findings suggest that surveillance within 1 year may be of low yield. Further clinical trials and cohort studies investigating cost-effectiveness of surveillance schedules and impact on quality of life of patients under surveillance will provide further insight to optimize follow-up.

BACKGROUND: The interplay between HCV, DM, and DAA therapy is poorly understood. We compared HCV infection characteristics, treatment uptake, and treatment outcomes in patients with and without DM. METHODS: A retrospective cohort study was conducted using data from The Ottawa Hospital Viral Hepatitis Program. Statistical comparisons between diabetes and non-diabetes were made using χ2 and t-tests. Logistic regression analyses were performed to assess predictors of DM and SVR. RESULTS: One thousand five hundred eighty-eight HCV patients were included in this analysis; 9.6% had DM. Patients with DM were older and more likely to have cirrhosis. HCC and chronic renal disease were more prevalent in the DM group. Treatment uptake and SVR were comparable between groups. Regression analysis revealed that age and employment were associated with achieving SVR. Post-SVR HCC was higher in DM group. CONCLUSION: The high prevalence of DM in our HCV cohort supports screening. Further assessment is required to determine if targeted, early DAA treatment reduces DM onset, progression to cirrhosis and HCC risk. Further studies are needed to determine if optimization of glycemic control in this population can lead to improved liver outcomes.

PURPOSE: The objective of this study was to compare the cost-effectiveness of preoperative octreotide therapy followed by surgery versus the standard treatment modality for growth-hormone secreting pituitary adenomas, direct surgery (that is, surgery without preoperative treatment) from a public third-party payer perspective. METHODS: We developed an individual-level state-transition microsimulation model to simulate costs and outcomes associated with preoperative octreotide therapy followed by surgery and direct surgery for patients with growth-hormone secreting pituitary adenomas. Transition probabilities, utilities, and costs were estimated from recent published data and discounted by 3% annually over a lifetime time horizon. Model outcomes included lifetime costs [2020 United States (US) Dollars], quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios (ICERs). RESULTS: Under base case assumptions, direct surgery was found to be the dominant strategy as it yielded lower costs and greater health effects (QALYs) compared to preoperative octreotide strategy in the second-order Monte Carlo microsimulation. The ICER was most sensitive to probability of remission following primary therapy and duration of preoperative octreotide therapy. Accounting for joint parameter uncertainty, direct surgery had a higher probability of demonstrating a cost-effective profile compared to preoperative octreotide treatment at 77% compared to 23%, respectively. CONCLUSIONS: Using standard benchmarks for cost-effectiveness in the US ($100,000/QALY), preoperative octreotide therapy followed by surgery may not be cost-effective compared to direct surgery for patients with growth-hormone secreting pituitary adenomas but the result is highly sensitive to initial treatment failure and duration of preoperative treatment.

In 2007, Australia introduced its most radical welfare reform in recent history, targeting Aboriginal communities with the aim of protecting children from harm. The 'income management' policy forced Aboriginal welfare recipients to spend at least half of their government transfers on essentials (e.g. food, housing), and less on non-essentials (e.g. alcohol, tobacco). By exploiting its staggered rollout, we estimate the impact of in utero exposure to the policy rollout on birthweight. We find that exposure to the income management policy reduced average birthweight robustly by 85 g and increased the risk of low birth weight by 3 percentage points. This finding is not explained by behavioral change (fertility, maternal risk behavior, access to care), or survival probabilities of at-risk fetuses. More likely, a lack of policy implementation planning and infrastructure led to acute income insecurity and stress during the rollout period, exacerbating the existing health inequalities it sought to address.

Long-term care facility (LTCF) residents have been disproportionately affected by coronavirus disease 2019 (COVID-19), from increased mortality and restrictive public health measures. The current study aims to describe the experiences of residents relocating between LTCFs at the onset of the COVID-19 pandemic. Emphasis was placed on residents' sense of home and how the pandemic and ensuing isolation affected their transition. This qualitative study follows the principles of constructivist grounded theory. Seven of 10 residents interviewed had cognitive impairment (mean age = 84 years). Four primary themes were elicited from the interviews focusing on residents' perceptions of their environment and highlights the value placed on privacy and control, the multifaceted feeling of loss during the pandemic, the importance of relationships as a source of comfort and pleasure, and resilience shown by residents in times of hardship. Our study indicates that residents experienced dichotomy and paradox during the pandemic, attempting to strike a balance between isolation and camaraderie, infection risk and mental health, and loss and resilience. The need for familial contact and socialization must be balanced against infection control measures. [Journal of Gerontological Nursing, 48(1), 29-33.].

AIM: Periventricular leukomalacia (PVL) is a term reserved to describe white matter injury in the premature brain. In this review article, the authors highlight the common and rare pathologies mimicking the chronic stage of PVL and propose practical clinico-radiological criteria that would aid in diagnosis and management. METHODS AND RESULTS: The authors first describe the typical brain MRI (magnetic resonance imaging) features of PVL. Based on their clinical presentation, pathologic entities and their neuroimaging findings were clustered into distinct categories. Three clinical subgroups were identified: healthy children, children with stable/nonprogressive neurological disorder, and those with progressive neurological disorder. The neuroradiological discriminators are described in each subgroup with relevant differential diagnoses. The mimics were broadly classified into normal variants, acquired, and inherited disorders. CONCLUSIONS: The term "PVL" should be used appropriately as it reflects its pathomechanism. The phrase "white matter injury of prematurity" or "brain injury of prematurity" is more specific. Discrepancies in imaging and clinical presentation must be tread with caution and warrant further investigations to exclude other possibilities.

BACKGROUND: Pituitary adenomas (PAs) are common and often require complex multidisciplinary care with multiple specialists. This may result in a healthcare system that is challenging for patients to navigate. Audits of care at our institution revealed opportunities for improvement to better align care with patients' needs. METHODS: A quality improvement initiative that incorporated a patient advisory committee of patients who had received treatment for PA at our center and their family members were used to help identify opportunities for improvement. The patient-identified gaps in care included the need to coordinate and minimize appointments and the desire for better communication and education. Based on this information, changes were implemented to the pituitary program, including increasing access to the Multidisciplinary Clinic and developing a standardized and centralized triage process. RESULTS: A pre- and post-intervention analysis consisting of retrospective chart reviews revealed that these changes had an impact on wait times for first assessment, and a significant shift in the location of this first visit - with a larger proportion of patients being seen in the Multidisciplinary Clinic after an intervention. CONCLUSIONS: We demonstrate that patient involvement, beyond individual patient-physician interactions, can lead to meaningful and observable changes, and can improve the quality of care for PA.

BACKGROUND: Kidney transplant immunosuppressive medications are known to impair glucose metabolism, causing worsened glycemic control in patients with pre-transplant diabetes mellitus (PrTDM) and new onset of diabetes after transplant (NODAT). OBJECTIVES: To determine the incidence, risk factors, and outcomes of both PrTDM and NODAT patients. DESIGN: This is a single-center retrospective observational cohort study. SETTING: The Ottawa Hospital, Ontario, Canada. PARTICIPANT: A total of 132 adult (>18 years) kidney transplant patients from 2013 to 2015 were retrospectively followed 3 years post-transplant. MEASUREMENTS: Patient characteristics, transplant information, pre- and post-transplant HbA1C and random glucose, follow-up appointments, complications, and readmissions. METHODS: We looked at the prevalence of poor glycemic control (HbA1c >8.5%) in the PrTDM group before and after transplant and compared the prevalence, follow-up appointments, and rate of complications and readmission rates in both the PrTDM and NODAT groups. We determined the risk factors of developing poor glycemic control in PrTDM patients and NODAT. Student t-test was used to compare means, chi-squared test was used to compare percentages, and univariate analysis to determine risk factors was performed by logistical regression. RESULTS: A total of 42 patients (31.8%) had PrTDM and 12 patients (13.3%) developed NODAT. Poor glycemic control (HbA1c >8.5%) was more prevalent in the PrTDM (76.4%) patients compared to those with NODAT (16.7%; P < .01). PrTDM patients were more likely to receive follow-up with an endocrinologist (P < .01) and diabetes nurse (P < .01) compared to those with NODAT. There were no differences in the complication and readmission rates for PrTDM and NODAT patients. Receiving a transplant from a deceased donor was associated with having poor glycemic control, odds ratio (OR) = 3.34, confidence interval (CI = 1.08, 10.4), P = .04. Both patient age, OR = 1.07, CI (1.02, 1.3), P < .01, and peritoneal dialysis prior to transplant, OR = 4.57, CI (1.28, 16.3), P = .02, were associated with NODAT. LIMITATIONS: Our study was limited by our small sample size. We also could not account for any diabetes screening performed outside of our center or follow-up appointments with family physicians or community endocrinologists. CONCLUSION: Poor glycemic control is common in the kidney transplant population. Glycemic targets for patients with PrTDM are not being met in our center and our study highlights the gap in the literature focusing on the prevalence and outcomes of poor glycemic control in these patients. Closer follow-up and attention may be needed for those who are at risk for worse glycemic control, which include older patients, those who received a deceased donor kidney, and/or prior peritoneal dialysis.
CONTEXTE: Les médicaments immunosuppresseurs prescrits à la suite d'une transplantation rénale sont connus pour altérer le métabolisme du glucose, rendant plus difficile le contrôle de la glycémie chez les patients diabétiques avant l'intervention (DbAvT diabétiques avant la transplantation) et chez les patients devenus diabétiques après l'intervention (NDbApT nouveaux diabétiques après la transplantation). OBJECTIF: Déterminer l'incidence d'un contrôle de la glycémie déficient, les facteurs de risque et les résultats chez les patients DbAvT et NDbApT. TYPE D'ÉTUDE: Il s'agit d'une étude de cohorte rétrospective et observationnelle qui s'est tenue dans un seul center. CADRE: L'hôpital d'Ottawa (Ontario), au Canada. SUJETS: Les adultes receveurs d'une greffe rénale entre 2013 et 2015 (n=132) ont été suivis rétrospectivement sur une période de trois ans post-transplantation. MESURES: Les caractéristiques des patients, les informations relatives à la greffe, les taux d'HbA1C et la glycémie pré- et post-transplantation, les rendez-vous de suivi, les complications et les réadmissions. MÉTHODOLOGIE: Nous nous sommes d'abord penchés sur la prévalence d'un contrôle glycémique déficient (HbA1c >8,5 %) dans le groupe DbAvT avant et après la greffe, puis nous avons comparé la prévalence, les rendez-vous de suivi et les taux de complications et de réadmission pour les deux groupes. Nous avons déterminé les facteurs de risque d'un mauvais contrôle glycémique chez les patients DbAvT et NDbApT. Les moyennes ont été comparées à l'aide du test t de Student, et le test du chi carré a servi à comparer les pourcentages. L'analyze univariée pour déterminer les facteurs de risque a été effectuée par régression logistique. RÉSULTATS: Parmi les 132 patients étudiés, 42 (31,8 %) étaient DbAvT et 12 (13,3 %) le sont devenus après l'intervention (NDbApT). La prévalence d'un mauvais contrôle de la glycémie (HbA1c >8,5 %) était plus élevée chez les patients DbAvT que chez les patients NDbApT (76,4 % contre 16,7 %; p<0,01). Les patients DbAvT étaient plus susceptibles d'être suivis par un endocrinologue (p<0.01) et une infirmière spécialisée en diabète (p<0.01) comparativement aux patients NDbApT. Aucune différence n'a été observée entre les deux groupes pour les taux de complications et de réadmission. Un greffon provenant d'un donneur décédé a été associé à un contrôle glycémique déficient (RC=3,34; IC 95 :1,08-10,4; p=0,04). Le développement d'un NDbApT a été associé à la fois à l'âge du patient (RC=1,07 IC 95: 1,02-1,3; p<0,01) et à un traitement de dialyze péritonéale (OR=4,57; IC 95: 1,28-16,3; p=0,02) avant la greffe. LIMITES: Nos résultats sont limités par la faible taille de l'échantillon. Nous n'avons pu rendre compte des dépistages effectués hors de notre center ni des rendez-vous de suivi avec un médecin de famille ou un endocrinologue dans la communauté. CONCLUSION: Un contrôle glycémique déficient est fréquent chez les patients greffés d'un rein. Les cibles glycémiques des patients DbAvT ne sont pas rencontrées dans notre center et notre étude met en lumière les lacunes de la littérature sur la prévalence et les résultats d'un mauvais contrôle glycémique chez ces patients. Un suivi plus étroit et une plus grande attention pourraient être nécessaires pour les patients susceptibles de voir leur contrôle glycémique se détériorer, notamment les personnes âgées, les receveurs d'un rein provenant d'un donneur décédé et les patients traités par dialyze péritonéale avant l'intervention.
RESUMEN
The hepatitis C virus (HCV) infects 185 million people worldwide, and diabetes mellitus (DM) affects 415 million. There has long been a possible association between DM and liver outcomes for patients with HCV infection. We present two cases of worsening glucose resistance and one case of emergent type 1 DM after completion of HCV. The complex interactions between HCV infection and both type 1 and type 2 DM have not yet been elucidated. In addition, consequences and side effects of treatment options for HCV have not been fully studied in the diabetic population. Our case series illustrates a potential complication of HCV treatment, which may warrant additional consideration prior to initiation of therapy as well as monitoring and surveillance post-cure.
Le virus de l'hépatite C (VHC) infecte 185 millions de personnes dans le monde, et le diabète en atteint 415 millions. On sait depuis longtemps qu'il y a une association possible entre le diabète et les affections hépatiques chez les patients infectés par le VHC. Les auteurs présentent deux cas d'aggravation de la résistance au glucose et un cas d'apparition du diabète de type 1 après la fin du traitement du VHC. Les interactions complexes entre l'infection par le VCH et le diabète de type 1 et de type 2 ne sont pas encore établies. De plus, les conséquences et les effets secondaires des possibilités de traitement du VHC n'ont pas fait l'objet d'études approfondies dans la population diabétique. La présente série de cas fait état d'une complication potentielle du traitement du VHC, qui pourrait justifier un examen supplémentaire avant le début du traitement, de même qu'un contrôle et une surveillance par la suite.
RESUMEN
BACKGROUND AND OBJECTIVES: Agitation is common in people living with dementia especially at the end of life. We examined how staff interpreted agitation behavior in people with dementia nearing end of life, how this may influence their responses and its impact on the quality of care. RESEARCH DESIGN: Ethnographic study. Structured and semi-structured non-participant observations (referred to subsequently in this paper as "structured observations") of people living with dementia nearing the end of life in hospital and care homes (south-east England) and in-depth interviews with staff, conducted August 2015-March 2017. METHODS: Three data sources: 1) detailed field notes, 2) observations using a structured tool and checklist for behaviors classed as agitation and staff and institutional responses, 3) staff semi-structured qualitative interviews. We calculated the time participants were agitated and described staff responses. Data sources were analyzed separately, developed continuously and relationally during the study and synthesized where appropriate. RESULTS: We identified two main 'ideal types' of staff explanatory models for agitation: In the first, staff attribute agitated behaviors to the person's "moral judgement", making them prone to rejecting or punitive responses. In the second staff adopt a more "needs-based" approach in which agitation behaviors are regarded as meaningful and managed with proactive and investigative approaches. These different approaches appear to have significant consequences for the timing, frequency and quality of staff response. While these models may overlap they tend to reflect distinct organizational resources and values. CONCLUSIONS: Care worker knowledge about agitation is not enough, and staff need organizational support to care better for people living with dementia towards end of life. Positional theory may help to explain much of the cultural-structural context that produces staff disengagement from people with dementia, offering insights on how agitation behavior is reframed by some staff as dangerous. Such behavior may be associated with low-resource institutions with minimal staff training where the personhood of staff may be neglected.

BACKGROUND: Diabetic ketoacidosis (DKA) and hyperglycemic hyperosmolar state (HHS) are life-threatening complications of diabetes mellitus which require prompt treatment with large volume crystalloid fluid administration. A variety of crystalloid fluids is currently available for use and differs in their composition and ion concentrations. While there are potential pros and cons for different crystalloid fluids, it remains unknown if any particular fluid confers a clinical outcome benefit over others in the treatment of hyperglycemic emergencies. METHODS: A systematic search of MEDLINE, Embase, and the Cochrane Library of Systematic Reviews will be conducted to identify eligible studies, which will include observational and interventional studies involving adult and pediatric patients admitted to the hospital with either DKA or HHS. The interventions will include intravenous treatment with 0.9% saline versus other buffered (Ringer's lactate, Hartmann's, etc.), and non-buffered (0.45% saline) crystalloid fluids. The primary outcome is mortality at the latest follow-up time point. Secondary outcomes will include mortality at specific time points, length of hospital stay, development of acute kidney injury, requirement for renal replacement therapy, altered level of consciousness, and the time to normalization of several serum biochemical parameters. Where appropriate, meta-analyses will be performed for the outcomes and conducted separately for adult and pediatric patient populations. DISCUSSION: DKA and HHS are dangerous complications of diabetes mellitus and account for significant morbidity and mortality. Given the importance of crystalloid fluid administration in the management of these conditions, a systematic synthesis of the existing evidence base will identify potential evidence gaps and may help guide future clinical practice.
