HbA1c levels in schoolchildren with type 1 diabetes are seasonally variable and dependent on weather conditions
Aims/hypothesis: We evaluated seasonal HbA changes in children with type 1 diabetes and its relation with measures of weather conditions. Methods: HbA changes over more than 3 years were evaluated in type 1 diabetic patients who were younger than 18 years and had diabetes duration of more than 12 months, and correlated with measures of weather conditions (ambient temperature, hours of sunshine and solar irradiance). After comparison of autocorrelation patterns, patterns of metabolic control and meteorological data were evaluated using Spearman rank correlation. Results: A total of 3,935 HbA measurements in 589 school (â„7 years) and 88 preschool (<7 years) children were analysed. Mean (±SD) HbA level for the whole study period was 7.65±1.12%. The lowest HbA levels were observed in late summer and the highest in winter months, with differences consistently exceeding 0.44%. Autocorrelation analysis of HbA levels in schoolchildren showed a sine-wave pattern with a cycle length of roughly 12 months, which mirrored changes in ambient temperature. Strong negative correlations of HbA with ambient temperature (R=â0.56; p=0.0002), hours of sunshine (R=â0.52; p=0.0007) and solar irradiance (R=â0.52; p=0.0006) were present in schoolchildren, but not in preschoolers (pâ„0.29 for each correlation). Conclusions/interpretation: Seasonal changes of HbA levels in schoolchildren with type 1 diabetes are a significant phenomenon and should be considered in patient education and diabetes management. They may potentially affect the results of clinical trials using HbA levels as their primary outcome, as well as HbA-based diagnosis of diabetes
Consumer and staff perspectives of the implementation frequency and value of recovery and wellbeing oriented practices
Background: Despite advances in our understanding of what mental health systems and services can do to enhance recovery and wellbeing outcomes for people seeking support, there is limited evidence demonstrating that this body of work has translated successfully into mental health service practice. The Collaborative Recovery Model (CRM) is a practice framework that has been designed to support application of recovery and wellbeing oriented principles and practices within mental health service delivery. The aims of this study were to assess consumer and staff perceptions of implementation frequency during service engagement and the value of this approach for assisting recovery within a setting where the CRM approach had been adopted. Methods: The setting was a large Australian community managed mental health organisation. The study involved a cross-sectional analysis of consumer (n = 116) and staff practitioner (n = 62) perspectives. A series of paired sample t-tests assessed for differences between consumer and staff perceptions of the: (i) importance of key practice elements for assisting recovery, and the (ii) frequency that key practice elements are utilised during engagement sessions. Spearman\u27s r correlational analysis explored associations between importance, frequency and helpfulness of sessions. Results: Key practice elements of the model were applied during service interactions at a high level and perceived by the majority of consumers and staff participants as being important or very important for assisting recovery. Significant moderate correlations were found between the extent that practice elements were valued and the level at which they were applied. Higher levels of implementation of CRM practices were associated with higher ratings of perceived session helpfulness. The strongest association was between \u27encouragement to set tasks to complete between support visits\u27 and perceived helpfulness. Conclusions: Consumer and staff responses revealed that the key practice elements of the CRM were frequently implemented during service engagement interactions and were seen as valuable for assisting recovery. The level of agreement between raters suggests firstly, that the key practice elements were apparent and able to be rated as occurring, and secondly that the CRM approach is seen as responsive to consumer needs. The results have implications for translating recovery and wellbeing oriented knowledge into mental health service practice

Improving health-related quality of life and reducing suicide in primary care: Can social problemâsolving abilities help?
Problem-solving deficits and poor healthârelated quality of life are associated with suicide risk; yet, little is known about the interrelations between these variables. In 220 primary care patients, we examined the potential mediating role of physical and mental healthârelated quality of life on the relation between social problemâsolving ability and suicidal behavior. Participants completed the Suicidal Behaviors Questionnaire-Revised, Social Problem Solving Inventory-Revised, and Short-Form 36 Health Survey. Utilizing bootstrapped mediation, our hypotheses were partially supported; mediating effects were found for mental healthârelated quality of life on the relation between social problem-solving and suicidal behavior. Physical healthârelated quality of life was not a significant mediator. Greater social problemâsolving ability is associated with better mental healthârelated quality of life and, in turn, to less suicidal behavior. Interventions promoting social problemâsolving ability may increase quality of life and reduce suicide risk in primary care patients
The effects of storage conditions on long-chain polyunsaturated fatty acids, lipid mediators, and antioxidants in donor human milk - A review.
Donor human milk (DHM) is the recommended alternative, if maternal milk is unavailable. However, current human milk banking practices may negatively affect the nutritional quality of DHM. This review summarises the effects of these practices on polyunsaturated fatty acids, lipid mediators and antioxidants of human milk. Overall, there is considerable variation in the reported effects, and further research is needed, particularly with lipid mediators and antioxidants. However, to preserve nutritional quality, DHM should be protected from light exposure and storage at 4âŻÂ°C minimised, to prevent decreases in vitamin C and endocannabinoids and increases in free fatty acids and lipid peroxidation products. Storage at -20âŻÂ°C prior to pasteurisation should also be minimised, to prevent free fatty increases and total fat and endocannabinoid decreases. Storage â€-70âŻÂ°C is preferable wherever possible, although post-pasteurisation storage at -20âŻÂ°C for three months appears safe for free fatty acids, lipid peroxidation products, and total fat content
Optimized sequential extraction for carbonates: Quantification and ÎŽ13C analysis of calcite, dolomite and siderite
Siderite is present in diverse types of rocks and sediments, but its quantification is cumbersome when present in relatively low contents. A new analytical method for the sequential separation of different carbonate phases is presented. The separation, quantification and characterization of the carbonates is based on different kinetic reactions during acid digestion in combination with monitoring the solution composition and the concomitant release of CO2. Trapping the released gasses permits the isotopic characterization (ÎŽ13C) of the different phases. Based on published rate laws, an idealized model was built to identify pH and temperature conditions for optimal separation of the various carbonates by taking the size distribution of carbonate particles into consideration. Results from the theoretical survey were implemented in an extraction scheme, which was optimized and evaluated by tests on pure mineral phases and their mixtures. Further tests on a diverse array of sediment and rock samples validated the specificity and reproducibility of the method
Long Covid-19: Proposed Primary Care Clinical Guidelines for Diagnosis and Disease Management
Long COVID-19 may be defined as patients who, four weeks after the diagnosis of SARS-Cov-2 infection, continue to have signs and symptoms not explainable by other causes. The estimated frequency is around 10% and signs and symptoms may last for months. The main long-term manifestations observed in other coronaviruses (Severe Acute Respiratory Syndrome (SARS), Middle East respiratory syndrome (MERS)) are very similar to and have clear clinical parallels with SARS-CoV-2: mainly respiratory, musculoskeletal, and neuropsychiatric. The growing number of patients worldwide will have an impact on health systems. Therefore, the main objective of these clinical practice guidelines is to identify patients with signs and symptoms of long COVID-19 in primary care through a protocolized diagnostic process that studies possible etiologies and establishes an accurate differential diagnosis. The guidelines have been developed pragmatically by compiling the few studies published so far on long COVID-19, editorials and expert opinions, press releases, and the authors' clinical experience. Patients with long COVID-19 should be managed using structured primary care visits based on the time from diagnosis of SARS-CoV-2 infection. Based on the current limited evidence, disease management of long COVID-19 signs and symptoms will require a holistic, longitudinal follow up in primary care, multidisciplinary rehabilitation services, and the empowerment of affected patient groups
