Background: Hypoglycemia, especially at old age, can lead to several major problems, such as falls and cognitive deficits. The aim of our study was to detect hypoglycemia in older persons with and without diabetes mellitus type 2 (T2DM).Methods: The frequency and duration of hypoglycemia/hyperglycemia was studied in ambulatory geriatric (>75 years), non-diabetic persons (Group 1, n=10), using real time Continuous Glucose Monitoring (CGM, Dexcom G6), and in age- and sex-matched cognitively-healthy, T2DM patients having HbA1c levels < 9.0% (Group 2, n=10). The device was used during 20 days per person, who was blinded for the values on the receiver (except in case of severe hypo- or hyperglycemia). Data were stored for further analysis on the Dexcom Clarity Portal.Results: Hypoglycemia occurred frequently in older persons without T2DM, despite absence of hypoglycemia-inducing medication. In this group, people had 0.50% (median value) of the time glycemic values below 70 mg/dL, most of the episodes happened during nighttime. Conclusions: Our study demonstrates that hypoglycemia occurs frequently in non-diabetic older persons. Further studies are needed to determine whether this could be part of the normal aging process, and to determine if hypoglycemia might contribute to cognitive deterioration.

Objectives To explore the quality of interprofessional teamwork in acute geriatric care and to build a model of team types. Design Cross-sectional multicenter study. Setting Acute geriatric units in Belgium. Participants Team members of different professional backgrounds. Measurements Perceptions of interprofessional teamwork among team members of 55 acute geriatric units in Belgium were measured using a survey covering collaborative practice and experience, managerial coaching and open team culture, shared reflection and decision-making, patient files facilitating teamwork, members’ belief in the power of teamwork, and members’ comfort in reporting incidents. Cluster analysis was used to determine types of interprofessional teamwork. Professions and clusters were compared using analysis of variance. Results The overall response rate was 60%. Of the 890 respondents, 71% were nursing professionals, 20% other allied health professionals, 5% physicians, and 4% logistic and administrative staff. More than 70% of respondents scored highly on interprofessional teamwork competencies, consultation, experiences, meetings, management, and results. Fewer than 55% scored highly on items about shared reflection and decision-making, reporting incidents from a colleague, and patient files facilitating interprofessional teamwork. Nurses in this study rated shared reflection and decision-making lower than physicians on the same acute geriatric units (P < .001). Using the mean score on each of the six areas, four clusters that differed significantly in all areas were identified using hierarchical cluster analysis and scree plot analysis (P < .001). Conclusion Interprofessional teamwork in acute geriatric units is satisfactory, but shared reflection and decision-making needs improvement. Four types of interprofessional teamwork are identified and can be used to benchmark the teamwork of individual teams.

Plasma gonadotropins were measured in 126 postmenopausal women (age range 69-90 years) admitted to a geriatric ward. After clinical examination, patients were classified as 'acutely or severely ill' or as 'not ill'. Plasma gonadotropins were compared between both groups. Logistic regression was used to select clinical and/or biochemical parameters which differentiated patients with abnormal, low gonadotropins from patients with high gonadotropin concentrations. Plasma gonadotropins were significantly lower in the 'acutely or severely ill' than in the 'healthy' patient group. By logistic regression, blood sedimentation rate, total protein concentration, and serum thyrotropin concentration were significantly correlated with low gonadotropins. Linear regression analysis showed a significant linear relationship between plasma gonadotropins and age (at least for ages over 80 years), blood sedimentation rate (at values more than 65 mm) and total protein concentration. Marked suppression of plasma gonadotropins was frequently found to occur in acutely ill postmenopausal women, in relation to biochemical parameters of acute illness such as blood sedimentation rate, total protein concentration, and serum thyrotropin. In addition, ageing per se seems characterized by a progressive attenuation of the high postmenopausal gonadotropin levels.
