Comparison between a Flash Glucose Monitoring System and a Portable Blood Glucose Meter for Monitoring of Cats with Diabetic Ketosis or Ketoacidosis.

Cats with diabetic ketosis or ketoacidosis DK(A) require intensive glucose monitoring. The aim of this study was to assess the agreement between a portable blood glucose meter (PBGM) and a flash glucose monitoring system (FGMS; FreeStyle Libre 2.0 Abbott®) measuring interstitial glucose in cats with DK(A). Ten client-owned cats with naturally occurring DK(A) were prospectively enrolled. Glucose concentrations were assessed with both methods every 1-3 h until resolution of DK(A), and every 4-8 h thereafter. While the median FGMS measured glucose concentration (14.3 mmol/L) was significantly lower than the median PBGM measured glucose concentration (19 mmol/L) (p < 0.001), the overall correlation between the FGMS and PBGM was high (r = 0.88; p < 0.001). In the Parkes error grid analysis, 98.3% of measurements fell in zones A and B. Bland-Altman plot analysis demonstrated that in the low glycaemic range (BG < 5.5 mmol/L), 50% of FGMS measurements deviated more than ±0.83 mmol/L, and in the high glycaemic range (BG > 5.5 mmol/L), 81% of results deviated >15% from the PBGM measurements. There was significant inter-individual variation in the difference between glucose concentrations measured by the FGMS and PBGM (p < 0.001). In spite of being more easily tolerated and easier to use, currently this method cannot be recommended for routine monitoring of cats with DK(A).

Performance of an interstitial glucose monitoring device in patients with type 1 diabetes during haemodialysis.

Background: The use of interstitial glucose monitoring devices such as flash glucose monitoring has been shown to be beneficial in patients with type 1 diabetes mellitus (T1DM). However, these devices have been little studied in patients with diabetes treated by chronic haemodialysis (HD). Methods: The goal of this prospective, observational, multicentric study was to evaluate the analytical performance of the FreeStyle Libre 2 (FSL2) sensor in T1DM patients during HD sessions. During three HD sessions, interstitial fluid glucose (ISFG) concentrations given by the FSL2 were compared every 15 minutes with blood glucose (BG) concentrations obtained simultaneously. BG concentrations were measured by two different glucometers: the Accu-Chek Guide and StatStrip meters. Results: Twelve HD patients were included, with a mean age of 54 ± 11 years and a mean diabetes duration of 36.5 ± 11.6 years. Dialysis vintage was 35 ± 22 months. A total of 565 pairs of ISFG/BG values were available for analysis. The mean absolute relative difference, defined as the mean of the absolute relative differences between the ISFG and BG measurements, was 17.4% and 20.9% when the ISFG was compared with the StatStrip meter or Accu-Chek Guide, respectively. Interstitial results tend to underestimate blood results, but all values were classified as having clinically acceptable error. The differences observed remained stable during the dialysis session and were not associated with the ultrafiltration rate. Conclusion: Use of the FSL2 interstitial glucose monitoring device in HD patients with T1DM is clinically acceptable, even though the accuracy of the device is generally poorer than in studies including non-dialysis patients.

Breaking through diabetes management barriers: Assessing the accuracy of Freestyle Libre Pro flash continuous glucose monitoring in diabetes patients with myocardial infarction.

Purpose: The objective of this study was to assess the accuracy of FreeStyle Libre Pro (FSL-Pro) flash continuous glucose monitoring (CGM) in patients with type 2 diabetes mellitus (T2DM) and acute myocardial infarction (AMI). Methods: A single-arm, single-center prospective study was conducted in the cardiac care unit from January 2021 to September 2023. Patients underwent finger-prick blood glucose (FPBG) testing before breakfast (6:00 am) and after meals (at 9:00, 13:00, 19:00 pm), along with CGM during their hospitalization. Statistical analyses included mean differences (MDs), mean absolute relative difference (MARDs) of blood glucose levels, and hypoglycemia occurrences. A Bland-Altman plot analysis and Pearson correlation were performed. Results: Ninety-seven T2DM and AMI patients underwent CGM for up to 72 h (1142 monitoring point). Mean daily BG, Fasting plasma glucose (FPG) and mean postprandial plasma glucose (PPG) were significantly lower by CGM than by FPBG with an estimated MD of -0.89 mmol/L in BG, -0.88 mmol/L in FPG, and -0.90 mmol/L in PPG, respectively. The maximum effect was mainly in the first day and then the difference was gradually declined (falling range, Day1, -1.24; Day 2, -0.70; Day 3, -0.68, mmol/L, respectively). The incidence rates of hypoglycemia and potential hypoglycemia was 1.57% and 8.5% higher, respectively, in CGM than in FBPG. A Bland-Altman Plot revealed some variability and bias between the two methods of measurement of glucose monitoring (p < .001). Pearson's correlation coefficient demonstrated a significant correlation between the mean BG, FPG, and PPG of CGM and FBPG (Pearson's coefficient: 0.92, 0.87, 0.92, respectively, p < .001). Conclusion: Compared with FPBG, FSL Pro-CGM showed lower mean glucose and higher hypoglycemia detection in T2DM and AMI patients, especially in the first 24 h.

Difference in the accuracy of the third-generation algorithm and the first-generation algorithm of FreeStyle Libre continuous glucose monitoring device.

BACKGROUND: FreeStyle Libre uses the algorithm to calculate the sensor glucose (SG) levels. The manufacturer announced that they had changed the algorithm from the first generation (Gen. 1) to the third generation (Gen. 3). To assess the difference, we conducted an observational study to analyze the characteristics of the measurements by these two algorithms compared to the capillary blood glucose (BG) levels. METHODS: Participants with type 1 diabetes wore two FreeStyle Libre sensors, one on the left arm used with Gen. 3 algorithm, and another on the right arm used in combination with the FreeStyle Libre Reader with Gen. 1 algorithm. RESULTS: Data were collected from 11 participants. The Bland-Altman analysis of the measurements by Gen. 3 algorithm showed bias of 7.4 mg/dl and no proportional bias was observed (r=0.130). In contrast, the Bland-Altman analysis of the measurements by Gen. 1 algorithm showed bias of 4.4 mg/dl and proportional bias was observed (r=0.424). The MARD of Gen. 3 algorithm and Gen. 1 algorithm was 11.9±9.0% and 9.7±8.3%, respectively (P=0.053). CONCLUSION: No proportional bias in the measurements by Gen. 3 algorithm was observed, but in those by Gen. 1 algorithm. J. Med. Invest. 71 : 225-231, August, 2024.

Age-dependent haemogram and sex-dependent serum biochemistry values in semi-feral Konik horses.

INTRODUCTION: Semi-feral, free-roaming Konik polski horses are used in some European countries for preserving semi-open pasture landscapes. The estimation of their health status is still limited by insufficient data on various blood parameters. Therefore, our study aimed at the sex- and age-dependent analysis of haemogram and selected biochemistry parameters in healthy, semi-feral Koniks. In order to reach this aim, we took blood samples from 53 female and 18 male (8 uncastrated, 10 castrated) Koniks living in two Middle German nature reserves. They were of different age (9-266 months) and without signs of illness. Blood samples were analysed by an accredited laboratory. We identified age- but not sex-dependent changes in the white blood cell count (WBC). Higher age mainly caused a decrease in lymphocytes. Therefore, WBC correlated negatively and granulocyte-to-lymphocyte ratio positively with increasing age. Serum values of selected biochemical parameters did not depend on age but showed some sex-related differences. In this regard, serum total protein, triglyceride and the enzymatic activities of alkaline phosphatase, aspartate transaminase and g-glutamyltransferase were higher in males than females. However, the sex dependency of these enzymatic activities was restricted to uncastrated males. They also showed higher serum values for calcium and selenium than castrated males or all females. As far as the respective group sizes permitted, we then calculated age- or sex-dependent reference interval values for all parameters analysed. These values improve now the estimation of the health status of semi-feral, free-roaming Konik horses and provide a stable basis for future studies.

INTRODUCTION: Les chevaux Konik Polski semi-sauvages en liberté sont utilisés dans certains pays européens pour préserver les paysages de pâturages semi-ouverts. L'estimation de leur état de santé est encore limitée par le manque de données sur divers paramètres sanguins. C'est pourquoi notre étude visait à analyser, en fonction du sexe et de l'âge, l'hémogramme et certains paramètres biochimiques chez des Konik semi-sauvages en bonne santé. Pour ce faire, nous avons prélevé des échantillons de sang sur 53 femelles et 18 mâles (8 non castrés, 10 castrés) vivant dans deux réserves naturelles d'Allemagne centrale. Ils étaient d'âges différents (9-266 mois) et ne présentaient aucun signe de maladie. Les échantillons de sang ont été analysés par un laboratoire accrédité. Nous avons identifié des changements dans la numération des globules blancs (WBC) qui dépendent de l'âge mais non du sexe. L'augmentation de l'âge a principalement entraîné une diminution des lymphocytes. Par conséquent, le nombre de globules blancs est corrélé négativement et le rapport granulocytes/lymphocytes positivement avec l'augmentation de l'âge. Les valeurs sériques de certains paramètres biochimiques ne dépendaient pas de l'âge, mais présentaient certaines différences liées au sexe. À cet égard, les protéines totales sériques, les triglycérides et les activités enzymatiques de la phosphatase alcaline, de la transaminase aspartate et de la γ-glutamyltransférase étaient plus élevés chez les mâles que chez les femelles. Cependant, la dépendance de ces activités enzymatiques par rapport au sexe était limitée aux mâles non castrés. Ces derniers présentaient également des valeurs sériques de calcium et de sélénium plus élevées que les mâles castrés ou que toutes les femelles. Dans la mesure où la taille des groupes respectifs le permettait, nous avons ensuite calculé des valeurs d'intervalle de référence dépendant de l'âge ou du sexe pour tous les paramètres analysés. Ces valeurs améliorent désormais l'estimation de l'état de santé des chevaux Konik semi-sauvages en liberté et fournissent une base stable pour les études futures.

Assessment of pulmonary nodules using [18F]-FDG PET/CT in deep inspiration breath-hold.

The characterization of pulmonary nodules (PN) is a primary indication for [18F]-FDG PET/CT. However, respiratory movements hinder this characterization, especially for PN located in the lower lobes. Various methods have been developed to improve image resolution. OBJECTIVE: Our objective was to compare the diagnostic efficacy of [18F]-FDG PET/CT in deep inspiration breath-hold (DIBH) versus free-breathing corrected by software, in the evaluation of PN. METHODS: We prospectively analyzed 51 patients to assess PN using [18F]-FDG PET/CT in DIBH and free-breathing corrected by software. A total of 84 nodules with an average size of 10 mm were analyzed, with pathological anatomy or medical treatment decisions by a multidisciplinary tumor board used as reference. RESULTS: A total of 84 PN were evaluated, comparing those in DIBH versus free-breathing, finding statistically significant differences in SUVmax values (p < 0.05) (mean SUVmax 3.7 in free-breathing vs. 5.33 in DIBH). When analyzed by location in lobes, we did not find statistically significant differences, though there was a trend towards higher SUVmax values in the lower lobes. [18F]-FDG PET/CT in DIBH showed high sensitivity (95%) and negative predictive value (NPV) (92%), indicating it may be a promising tool for PN characterization. CONCLUSIONS: The acquisition of [18F]-FDG PET/CT in DIBH significantly improves the sensitivity and diagnostic efficacy in the assessment of PN. Although no statistically significant differences were found based on location, there is a potential benefit for the lower lobes. These findings could support its use in clinical practice.

Hair reconstruction of the burned chin region using a pre-expanded free temporo-parietal skin flap. About a case.

Reconstruction of the chin region represents a technical challenge due to its three-dimensional configuration and its location close to the mouth. It requires both a functional approach by restoring mobility and an aesthetic approach by restoring the perioral furrows. For men who want to wear a beard, it becomes more difficult to choose the donor site for hairy skin. In that case, strategies of full thickness skin graft or pre-expanded loco-regional flaps are unusable. We propose here a functional, aesthetic and hairy reconstruction by performing a pre-expanded temporal free flap which allowed to resolve the problem of adjacent cervical contractures and to restore an integrated the bearded chin subunit.

Fat-free noncontrast whole-heart CMR with fast and power-optimized off-resonant water excitation pulses.

BACKGROUND: Cardiovascular MRI (CMR) faces challenges due to the interference of bright fat signals in visualizing structures like coronary arteries. Effective fat suppression is crucial, especially when using whole-heart CMR techniques. Conventional methods often fall short due to rapid fat signal recovery, leading to residual fat content hindering visualization. Water-selective off-resonant radiofrequency (RF) pulses have been proposed but come with tradeoffs between pulse duration, which increases scan time, and increased RF energy deposit, which limits their applicability due to specific absorption rate (SAR) constraints. The study introduces a lipid-insensitive binomial off-resonant (LIBOR) RF pulse, which addresses concerns about SAR and scan time, and aims to provide a comprehensive quantitative comparison with published off-resonant RF pulses for CMR at 3T. METHODS: A short (1ms) LIBOR pulse, with reduced RF power requirements, was developed and implemented in a free-breathing respiratory-self-navigated 3D radial whole-heart CMR sequence at 3T. A binomial off-resonant rectangular (BORR) pulse with matched duration, as well as previously published lipid-insensitive binomial off-resonant excitation (LIBRE) pulses (1ms and 2.2ms), were implemented and optimized for fat suppression in numerical simulations and validated in volunteers (n=3). Whole-heart CMR was performed in volunteers(n=10) with all four pulses. The signal-to-noise ratio (SNR) of ventricular blood, skeletal muscle, myocardium, and subcutaneous fat and the coronary vessel detection rates and sharpness were compared. RESULTS: Experimental results validated numerical findings and near homogeneous fat suppression was achieved with all four pulses. Comparing the short RF pulses (1ms), LIBOR reduced the RF power nearly two-fold compared with LIBRE, and three-fold compared with BORR, and LIBOR significantly decreased overall fat SNR from cardiac scans, compared to LIBRE and BORR. The reduction in RF pulse duration (from 2.2ms to 1ms) shortened the whole-heart acquisition from 8.5min to 7min. No significant differences in coronary arteries detection and sharpness were found when comparing all four pulses. CONCLUSION: LIBOR pulses enabled whole-heart CMR under 7minutes at 3T, with large volume fat signal suppression, while reducing RF power compared with LIBRE and BORR pulses. LIBOR is an excellent candidate to address SAR problems encountered in CMR sequences where fat suppression remains challenging and short RF pulses are required.

Case report: Hybrid reconstruction of quadriceps function after sarcoma resection using a reinnervated free flap and tendon transfer.

We describe a case of a leiomyosarcoma of the thigh, the resection of all the anterior muscular compartment, and the reanimation of knee extension, using a latissimus dorsi (LD) free flap and tendon transfer. Surgical technique and postoperative care management are described. Functional results, neuropathic pain, and range of motion (ROM) were assessed at 3 months and 12 months after discharge. A complete excision (R0) was carried out and rapid wound healing was obtained despite developing a seroma infection. The patient was able to walk without technical support nor limping at 3 months post-surgery. The patient was still in remission at 12 months follow-up, with Medical Research Council (MRC) scale assessed at 4/5 and ROM rated at 5-105°. In case of total quadriceps resection, knee extension reconstruction can be obtained with tendon transfers and reinnervated free muscular flaps. Combining these techniques could be a good strategy for rapid recovery, with optimal scarring and tissue coverage.

Treatment adherence to oral chemotherapy in patients with locally advanced or metastatic non-small cell lung cancer: Protocol for a hospital pharmacy-based real-world study.

OBJECTIVE: This article describes a study protocol for evaluating adherence to oral chemotherapy (OCT) in patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) in Spain. METHODS: This multicenter, observational, prospective study will be conducted by 6 hospital pharmacists from 6 Spanish hospitals. The study will include men and women aged 18 years or older with a diagnosis of locally advanced or metastatic NSCLC who are being treated or have been prescribed OCT. Once included, the patient will be active and prospectively followed up for 3 months, including 4 study visits to record information on sociodemographic variables, antineoplastic treatment and adherence, pharmaceutical care, clinical variables, and patient-reported outcomes (PRO) (the 3-level version of EQ-5D, the EORTC Core Quality of Life Questionnaire, the Brief Illness Perception Questionnaire, the Treatment Satisfaction with Medicines Questionnaire, and the PRO version of Common Terminology Criteria for Adverse Events). Twelve months after patient inclusion, we will record information on the disease progression status and dispensed prescriptions. The primary outcome is the percentage of treatment adherence that will be calculated based on the pill count as follows: the difference between the number of pills dispensed minus the number of unused pills will be divided by the number of days of treatment multiplied by the number of pills/day prescribed by the oncologist; this quotient will be multiplied by 100 to obtain the percentage of adherence. Based on the that pill count reconciliation, those with a percentage adherence >80% will be primarily categorized as adherent. Secondarily, treatment adherence will be also calculated based on the proportion of days covered and the 4-items Morisky Green Levine Medication Adherence Scale. To analyze the impact of patients' and treatment characteristics on adherence, bivariate analyses will be performed using different adherence cut-off points. To evaluate the impact of adherence on treatment efficacy as evaluated by progression-free survival, we will be using the Kaplan-Meier method and compare it with the log-rank test and univariate Cox regression analysis. CONCLUSIONS: We expect that our study will provide initial information on key aspects of adherence to OCT (i.e., measurement, facilitators, and barriers) and its relationship with patients' and clinically relevant outcomes in the setting of NSCLC, and that this information will help in designing pharmaceutical interventions to improve adherence.

The value of PET/CT radiomic texture analysis of primary mass and mediastinal lymph node on survival in patients with non-small cell lung cancer.

OBJECTIVE: This study was designed to determine the potential prognostic value of radiomic texture analysis and metabolic-volumetric parameters obtained from positron emission tomography (PET) in primary mass and metastatic hilar/mediastinal lymph nodes in stage 2-3 non-small cell lung cancer (NSCLC). METHODS: Images of patients diagnosed with stage 2-3 NSCLC who underwent 18F-FDG PET/CT imaging for staging up to 4 weeks before the start of treatment were evaluated using LIFEx software. Volume of interest (VOI) was generated from the primary tumor and metastatic lymph node separately, and volumetric and textural features were obtained from these VOIs. The relationship between the parameters obtained from PET of primary mass and the metastatic hilar/mediastinal lymph nodes with overall survival (OS) and progression-free survival (PFS) was analyzed. RESULTS: When radiomic features, gender and stage obtained from lymph nodes were evaluated by Cox regression analysis; GLCM_correlation (p: 0.033, HR: 4,559, 1.660-12.521, 95% CI), gender and stage were determined as prognostic factors predicting OS. In predicting PFS; stage, smoking and lymph node MTV (p: 0.033, HR: 1.008, 1.001-1.016, 95% CI) were determined as prognostic factors. However, the radiomic feature of the primary tumor could not show a significant relationship with either OS or PFS. CONCLUSIONS: In a retrospective cohort of NSCLC patients with Stage 2 and 3 disease, volumetric and radiomic texture characteristics obtained from metastatic lymph nodes were associated with PFS and OS. Tumor heterogeneity, defined by radiomic texture features of 18 F-FDG PET/CT images, may provide complementary prognostic value in NSCLC.

Use of perfusion device for free flap salvage after ischemia in swine.

INTRODUCTION: In free flap reconstruction, improving flap tolerance to warm ischemia (WI) is fundamental. WI is the result of a venous or arterial thrombosis, which can only be addressed through surgical revision. No additional treatments have shown superior efficacy at salvaging free flaps after or during WI. Custom perfusion machines (PM), used to reduce the intensity of lesions of the flap stored in cold ischemia, have not been evaluated for WI flap salvage. This proof-of-concept study assessed whether the Lifeport® perfusion machine could improve the salvage procedure's success rates after one hour of venous WI. METHODS: Five different groups were evaluated with four porcine latissimus dorsi free flaps included in each group. Depending on the group, the flaps were subjected to one hour of WI followed by revascularization, static hypothermic submersion, or dynamic Lifeport® perfusion. Additionally, two flap perfusion liquids were evaluated: KPS-1® and IGL-1®. Biopsies were performed before in vivo warm ischemia of the flap, after in vivo warm ischemia of the flap, and after one and two hours of preservation. Interstitial edema, muscular cell size and muscular diffuse necrosis were quantified by histological assessment. RESULTS: Static submersion did not demonstrate any efficacy for venous flap salvage. Dynamic perfusion on Lifeport® machine showed a significant improvement in tissue parameters. Thrombi and fibrine, present during the WI period, were no longer visible inside vessels and the perfusion machine flow evacuated the inflammatory cells and their substrates from the flap. The flap weights did not increase during perfusion time, confirming the benefits of the Lifeport® perfusion machine. CONCLUSION: Evaluating Lifeport® advantages on human free flap salvage is necessary to confirm the benefits for the tissue and to increase post-operative results after congestive free flap revision surgery.

Can flash glucose monitoring improve glucose management for Aboriginal and Torres Strait Islander peoples with type 2 diabetes? A protocol for a randomised controlled trial.

BACKGROUND: Aboriginal and Torres Strait Islander peoples are disproportionately impacted by type 2 diabetes. Continuous glucose monitoring (CGM) technology (such as Abbott Freestyle Libre 2, previously referred to as Flash Glucose Monitoring) offers real-time glucose monitoring that is convenient and easy to use compared to self-monitoring of blood glucose (SMBG). However, this technology's use is neither widespread nor subsidised for Aboriginal and Torres Strait Islander peoples with type 2 diabetes. Building on existing collaborations with a national network of Aboriginal and Torres Strait Islander communities, this randomised controlled trial aims to assess the effect of CGM compared to SMBG on (i) haemoglobin A1c (HbA1c), (ii) achieving blood glucose targets, (iii) reducing hypoglycaemic episodes and (iv) cost-effective healthcare in an Aboriginal and Torres Strait Islander people health setting. METHODS: This is a non-masked, parallel-group, two-arm, individually randomised, controlled trial (ACTRN12621000753853). Aboriginal and Torres Strait Islander adults with type 2 diabetes on injectable therapy and HbA1c ≥ 7.5% (n = 350) will be randomised (1:1) to CGM or SMBG for 6 months. The primary outcome is change in HbA1c level from baseline to 6 months. Secondary outcomes include (i) CGM-derived metrics, (ii) frequency of hypoglycaemic episodes, (iii) health-related quality of life and (iv) incremental cost per quality-adjusted life year gained associated with the CGM compared to SMBG. Clinical trial sites include Aboriginal Community Controlled Organisations, Aboriginal Medical Services, primary care centres and tertiary hospitals across urban, rural, regional and remote Australia. DISCUSSION: The trial will assess the effect of CGM compared to SMBG on HbA1c for Aboriginal and Torres Strait Islander people with type 2 diabetes in Australia. This trial could have long-term benefits in improving diabetes management and providing evidence for funding of CGM in this population.

Reduced Rate of Hospitalizations for Acute Diabetes Events Before and After FreeStyle Libre® System Initiation in Some People With Type 2 Diabetes on Insulin-Secretagogue Oral Drug Therapy Without Insulin in France.

Objective: Glycemic management in people with type 2 diabetes mellitus (T2DM) on insulin-secretagogue regimens without insulin is of importance, as this group still represents a significant proportion of patients. Risks for acute diabetes events (ADEs), including diabetic ketoacidosis (DKA) or hypoglycemia, using insulin-secretagogue drugs are well established. Few studies have suggested that continuous glucose monitoring (CGM) could be useful for monitoring glucose dynamics associated with the use of such therapies. To document this point an exploratory analysis was conducted in a group of individuals with noninsulin treated T2DM in France who are managed with oral insulin-secretagogues and initiating the FreeStyle Libre® system (FSL). Methods: A retrospective study of the French national SNDS reimbursement claims database (≈66 million French people) was conducted to identify people with T2DM on oral insulin-secretagogues and receiving a first reimbursement of FSL between August 1, 2017 and December 31, 2018. The analysis included data for the 12 months before and up to 24 months after FSL initiation. Hospitalizations for diabetes-related acute events were identified using ICD-10 codes as main or related diagnosis, for: hypoglycemic events; DKA events; comas; and hyperglycemia-related admissions. Results: A total of 1272 people with T2DM on insulin-secretagogues without insulin initiated FSL during the selection period. Of these, 7.15% had at least one hospitalization for any ADE in the year before FSL initiation, compared with 2.52% at 12 months and 2.83% at 24 months following FSL initiation. Reductions in ADEs were driven by -73% fewer admissions for ADEs related to diabetic ketoacidosis (DKA) or other hyperglycemia-related events. These patterns of reduced ADEs persisted after 2 years. Conclusions: This study suggests the value of the FSL system in reducing ADEs in some people with T2DM in France being treated with insulin-secretagogues without insulin. Characteristics of these patients remain to be documented.

A dose titration protocol for once-daily insulin glargine 300 U/mL for the treatment of diabetes mellitus in dogs.

BACKGROUND: In purpose-bred dogs, insulin glargine 300 U/mL (IGla300) has long duration of action, peakless time-action profile, and low potency, making it suitable for use as a basal insulin. HYPOTHESIS: To evaluate IGla300 in client-owned diabetic dogs monitored using a flash glucose monitoring system (FGMS). ANIMALS: Ninety-five client-owned diabetic dogs, newly diagnosed or previously treated with other insulin formulations, with or without concurrent diseases. METHODS: Prospective multi-institutional study. Clinical signs and standardized assessment of FGMS data, using treatment and monitoring guidelines established a priori, guided dose adjustments and categorization into levels of glycemic control. RESULTS: The initial IGla300 dose was 0.5 U/Kg q24h for newly diagnosed dogs and (median dose [range]) 0.8 U/Kg (0.2-2.5) q24h for all dogs. Glycemic control was classified as good or excellent in 87/95 (92%) dogs. The IGla300 was administered q24h (1.9 U/kg [0.2-5.2]) and q12h (1.9 U/kg/day [0.6-5.0]) in 56/95 (59%) and 39/95 (41%) dogs, respectively. Meal-time bolus injections were added in 5 dogs (0.5 U/kg/injection [0.3-1.0]). Clinical hypoglycemia occurred in 6/95 (6%) dogs. Dogs without concurrent diseases were more likely to receive IGla300 q24h than dogs with concurrent diseases (72% vs 50%, respectively; P = .04). CONCLUSIONS AND CLINICAL IMPORTANCE: Insulin glargine 300 U/mL can be considered a suitable therapeutic option for once-daily administration in diabetic dogs. Clinicians should be aware of the low potency and wide dose range of IGla300. In some dogs, twice-daily administration with or without meal-time bolus injections may be necessary to achieve glycemic control. Monitoring with FGMS is essential for dose titration of IGla300.

Continuous glucose monitoring with FreeStyle Libre PRO sensor in patients with type 2 diabetes and end-stage renal failure on haemoDIALysis (FSLPRO-DIAL pilot study).

AIMS: For end-stage renal disease (ESRD) patients with diabetes on haemodialysis, diabetes control is difficult to achieve. Hypoglycaemia is a major problem in these frailty subjects. Continuous glucose monitoring (CGM) devices appear therefore to be a good tool to help patients monitor their glycaemic control and to help practitioners optimize treatment. We aimed to compare the laboratory value of Hba1c with the sensor-estimated value of Hba1c (= glucose management indicator, GMI) in ESRD patients with type 2 diabetes (T2D) (with or without insulin treatment) on haemodialysis. Secondly, we aimed to identify CGM-derived monitoring parameters [time in range, time in hypo/hyperglycaemia, glycaemic variability (coefficient of variation, CV)] to identify patients at risk of frequent hypo- or hyperglycaemia. METHODS: The FSLPRO-DIAL pilot study (NCT04641650) was a prospective monocentric cohort study including 29 subjects with T2D who achieve the protocol. Inclusion criteria were: age ≥ 18 years, haemodialysis duration for at least 3 months, type 2 diabetes with no change in treatment for at least 3 months. Demographic data and blood sample were collected at the day of inclusion. Freestyle Libre pro IQ sensor (blinded CGM) was inserted for 14 days. After this period, all CGMs data were collected and analysed. RESULTS: Data were available for 27 patients. Mean age was 73 ± 10, mean BMI 27.2 kg/m2, mean duration of diabetes 16.9 years and mean dialysis duration 2.9 years. Twenty-four subjects were treated with insulin. Mean HbA1c was 6.6% (SD 1.2), and mean GMI was 6.7% (SD 0.9) (no significant difference, p = 0.3). Twelve subjects (44.4%) had a discordance between HbA1c and GMI of < 0.5%, 11 (40.8%) had a discordance between 0.5 and 1%, and only 4 (14.8%) had a discordance of > 1%. Mean time in range (70-180 mg/dl) was 71.9%, mean time below range (< 70 mg/dl) was 5.6%, and mean time above range (> 180 mg/dl) was 22.1%. Mean CV was 31.8%. For 13 out of 27 patients, we reduced antidiabetic treatment by stopping treatments or reducing insulin doses. CONCLUSION: In this pilot study, there was no global significant difference between HbA1c and GMI in this particular cohort with very well-controlled diabetes. However, the use of the sensor enabled us to identify an excessive time in hypoglycemia in this fragile population and to adapt their treatment.

The use of FreeStyle libre improves glycaemic control along with reducing diabetes burden and hospital admissions in a socially deprived Northwest English population.

Aim: This retrospective study aimed to use mixed (qualitative and quantitative) methods to evaluate the role of FSL in reducing hospital admissions due to all causes, HbA1c, and reported hypoglycaemic episodes in people with diabetes living in a socially deprived region of Northwest England. Methods: Data were collected retrospectively from previous consultations, which coincided with the 6th -week, 6th -month and annual review including blood tests, hospital admissions due to any cause and reported hypoglycaemia. Also, FSL assessment and satisfaction semi-structured questionnaire was done to assess the impact of FSL on diabetes management and quality of life. Mixed-effects models were used to assess glycaemic control and reductions in hospital admissions and reported hypoglycaemic episodes. Results: Just 127 patients met the inclusion criteria. A multivariate linear mixed model method that analyses HbA1c data longitudinally revealed mean differences (mmol/mol) between baseline and post-FSL measurements, estimated by restricted maximum likelihood method (REML) of 9.64 (six weeks), 7.68 (six months) and 7.58 (annual review); all with a corresponding p-value of < 0.0001. For DKA patients, the bootstrap method revealed a significant reduction in mean HbA1c of 25.5, 95% confidence interval (CI) [8.8, 42.6] mmol/mol. It is demonstrated that FSL use for one year resulted in 59% reduction in hospital admissions and 46% reduction in reported hypoglycaemic episodes. Conclusion: The use of FSL resulted in statistically significant reductions in hospital admissions, HbA1c and reported hypoglycaemic episodes among diabetics in a socially deprived Northwest region of England. These outcomes show a direct association with a higher questionnaire score. Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-024-01424-4.

Dietary Sugar and Anthropometrics among Young Children in the Guelph Family Health Study: Longitudinal Associations.

Purpose: Our understanding of the influence of sugar intake on anthropometrics among young children is limited. Most existing research is cross-sectional and has focused on sugar-sweetened beverages. The study objective was to investigate longitudinal associations between young children's total, free, and added sugar intake from all food sources at baseline with anthropometric measures at baseline and 18 months.Methods: The Guelph Family Health Study (GFHS) is an ongoing randomized controlled trial and a family-based health promotion study. Food records and anthropometric data were collected at baseline (n = 109, 55 males; 3.7 ± 1.1 y, mean ± SD) and 18 months (n = 109, 55 males; 5.1 ± 1.1 y) of the GFHS pilots. Associations between sugar intakes and anthropometrics were estimated using linear regression models with generalized estimating equations adjusted for age, sex, household income, and intervention status.Results: Total sugar intake was inversely associated with body weight at 18 months (P = 0.01). There was no effect of time on any other associations between total, free, and added sugar intakes and anthropometrics.Conclusions: Early life dietary sugar intakes may not relate to anthropometric measures in the short term. Further investigation into potential associations between dietary sugar intakes and anthropometric variables over longer time periods is warranted.

Cribado prenatal de aneuploidías mediante análisis de ácido desoxirribonucleíco libre total circulante en plasma materno. Revisión narrativa / Prenatal screening for aneuploidies by analysis of circulating total free deoxyribonucleic acid in maternal plasma. Narrative review

La prueba prenatal no invasiva es un método de cribado de aneuploidías fetales y de resultar con riesgo alto debe ser confirmado a través de prueba genética diagnóstica. Es la prueba de detección más sensible y específica para las aneuploidías fetales comunes y minimiza la realización de técnicas invasivas, solo para las gestantes con riesgo elevado. Se debe realizar asesoramiento genético pre- y poscribado. Este estudio tiene como objetivo describir los fundamentos básicos de la prueba prenatal no invasiva mediante el análisis del ácido desoxirribonucleíco libre circulante en plasma materno para cribado de aneuploidías, y de los métodos primordiales y avances en biología molecular incluyendo las tecnologías de secuenciación de nueva generación, que lo han facilitado, considerando sus beneficios y limitaciones al aplicarla en la práctica clínica, en este campo que cambia con tanta rapidez(AU)

The non-invasive prenatal test is a screening method for fetal aneuploidies and if the result is at high risk, it must be confirmed through diagnostic genetic test. It is the most sensitive and specific detection test for common fetal aneuploidies and minimizes the use of invasive techniques, only for pregnant women at high risk. Genetic counseling should be performed before and after screening. This study aims to describe the basic fundamentals of non-invasive prenatal testing by analyzing free circulating deoxyribonucleic acid in maternal plasma for aneuploidy screening, and the primary methods and advances in molecular biology, including next-generation sequencing technologies, which have facilitated it, considering its benefits and limitations when applying it in clinical practice, in this rapidly changing field(AU)
