Fístula gastrocólica como causa infrecuente de diarrea persistente en un paciente portador de gastrostomía radiológica percutánea / Gastrocolic fistula as infrequent cause of chronic diarrhea in a patient with percutaneous radiological gastrostomy

Introducción: la fístula gastrocólica supone una complicación infrecuente pero potencialmente grave de las sondas de gastrostomía. La sospecha clínica ante una diarrea de origen incierto que comienza tras el recambio de la sonda es clave para la detección y el tratamiento precoces. Caso clínico: se presenta el caso de un paciente portador de gastrostomía radiológica percutánea (PRG) que comienza con diarrea persistente tras el primer recambio de la sonda y desnutrición grave secundaria. Tras el fracaso de las medidas terapéuticas iniciales se amplían los estudios, con hallazgo de esta complicación en la imagen de TC. Se suspende el uso de esta sonda con resolución de la diarrea y evolución nutricional favorable. Discusión: este caso pone de manifiesto la importancia de incluir la fístula gastrocólica en el diagnóstico diferencial de la diarrea persistente en un paciente portador de sonda de gastrostomía.(AU)

Introduction: gastrocolic fistula is an infrequent but severe complication of percutaneous gastrostomy. Clinical suspicion in the presence of chronic diarrhea of unknown etiology manifesting after percutaneous radiological gastrostomy (PRG) tube replacement is key to early detection and treatment. Case report: we report the case of a patient with PRG that began with chronic diarrhea after tube replacement and developed severe malnutrition. Initial treatment was not effective, studies were extended with the finding of this complication in a CT image. The use of this tube was discontinued with resolution of diarrhea and a favorable nutritional outcome. Discussion: this case report shows the importance of considering gastrocolic fistula in the differential diagnosis of persistent diarrhea in a patient with a gastrostomy tube.(AU)

Trabecular bone score and bone remodelling markers identify perimenopausal women at high risk of bone loss.

CONTEXT: Bone loss is accelerated in the late perimenopause and early menopause. The date of the final menstrual period cannot be stated until 1 year after it has ended, and at that time, most of the rapid bone loss phase will have elapsed. Therefore, early detection of bone loss is crucial. OBJECTIVES: To evaluate the utility of bone turnover markers (BTM) to identify the women who are more likely to lose more bone mass during the transition to menopause and quantify the loss of bone quality measured by trabecular bone score (TBS). DESIGN, PATIENTS AND SETTING: Sixty-four healthy premenopausal women, mean age between 44 and 57 years old, were enrolled and followed up for 5 years. Clinical features, lifestyle, bone densitometry, TBS and BTM (CTX, P1NP and osteocalcin) were measured at baseline and follow-up. RESULTS: All women had densitometrically normal bone at the time of enrolment. After 5 years, 48.4% had normal bone mineral density, 45.8% low bone mass and 6.3% osteoporosis. Women with osteopenia/osteoporosis at follow-up had higher CTX and P1NP at enrolment compared with women with densitometrically normal bone. The areas under the curve for the prediction of low bone mass or osteoporosis were 0.69 (P = 0.011) for P1NP, 0.69 for CTX (P = 0.013) and 0.77 (P 0.001) for OC. A significant correlation was found between P1NP increase after 5 years and the decrease in lumbar bone density (r = -0.383, P = 0.002). At baseline, 7 (10.9%) women had deteriorated microarchitecture (TBS < 1.3). Three of these women developed osteoporosis and four osteopenia at follow-up. CONCLUSIONS: Women with higher P1NP and CTX and lower TBS at baseline had lower BMD in the transition to menopause suggesting these novel tools could have potential use in identifying women at high risk of rapidly decreasing bone mass.

Global epidemiology of hyperthyroidism and hypothyroidism.

Thyroid hormones are essential for growth, neuronal development, reproduction and regulation of energy metabolism. Hypothyroidism and hyperthyroidism are common conditions with potentially devastating health consequences that affect all populations worldwide. Iodine nutrition is a key determinant of thyroid disease risk; however, other factors, such as ageing, smoking status, genetic susceptibility, ethnicity, endocrine disruptors and the advent of novel therapeutics, including immune checkpoint inhibitors, also influence thyroid disease epidemiology. In the developed world, the prevalence of undiagnosed thyroid disease is likely falling owing to widespread thyroid function testing and relatively low thresholds for treatment initiation. However, continued vigilance against iodine deficiency remains essential in developed countries, particularly in Europe. In this report, we review the global incidence and prevalence of hyperthyroidism and hypothyroidism, highlighting geographical differences and the effect of environmental factors, such as iodine supplementation, on these data. We also highlight the pressing need for detailed epidemiological surveys of thyroid dysfunction and iodine status in developing countries.

Relationship between "a body shape index (ABSI)" and body composition in obese patients with type 2 diabetes.

BACKGROUND: Obesity is known to be related to the development of type 2 diabetes mellitus (T2D). The most commonly used anthropometric indicator (body mass index [BMI]) presents several limitations such as the lack of possibility to distinguish adipose tissue distribution. Thus, this study examines the suitability of a body shape index (ABSI) for prediction of body composition and sarcopenic obesity in obese or overweight T2D subjects. METHODS: Cross-sectional study in 199 overweight/obese T2D adults. Anthropometric (BMI, ABSI) and body composition (fat mass [FM], fat-free mass [FFM], fat mass index [FMI] and fat-free mass index, and the ratio FM/FFM as an index of sarcopenic obesity) data was collected, as well as metabolic parameters (glycated haemoglobin [HbA1c], mean blood glucose, fasting plasma glucose [FPG], high-density-lipoprotein cholesterol [HDL], low-density-lipoprotein cholesterol, total cholesterol, and triglycerides [TG] levels; the ratio TG/HDL was also calculated as a surrogate marker for insulin resistance). RESULTS: ABSI was significantly associated with age and waist circumference. It showed a statistically significant correlation with BMI exclusively in women. Regarding body composition, in men, ABSI was associated with FM (%), while in women it was associated with both FM and FFM. Both males and females groups with high ABSI scores were significantly older (men: 59.3 ± 10.8 vs 54.6 ± 10.1, p ≤ 0.05; women: 65.1 ± 9.8 vs 58.1 ± 13.3, p ≤ 0.005) and showed lower FFM values (men: 62.3 ± 9.0 vs 66.2 ± 9.3, p ≤ 0.05; women: 48.7 ± 5.6 vs 54.5 ± 8.9, p ≤ 0.001) compared with low-ABSI groups. Multiple linear regression revealed that ABSI independently predict FMI and the FM/FFM ratio in women. Sarcopenic obesity was identified in 70 (36.5%) individuals according to the FM/FFM ratio. The AUROC of ABSI was 63.1% (95% CI 54.6-71.6%; p = 0.003) and an ABSI value of 0.083 m11/6 kg-2/3 was the optimal threshold in discriminating patients with sarcopenic obesity (sensitivity: 48%, specificity: 73%). Moreover, a significant association between ABSI and FPG was found in men. CONCLUSIONS: ABSI could be useful to identify visceral and sarcopenic obesity in overweight/obese adults with T2D, adding some relevant clinical information to traditional anthropometric measures.

Is HOMA-IR a potential screening test for non-alcoholic fatty liver disease in adults with type 2 diabetes?

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the commonest hepatic disease in many parts of the World, with particularly high prevalence in patients with type 2 diabetes (T2DM). However, a good screening test for NAFLD in T2DM has not been established. Insulin resistance (IR) has been associated with NAFLD, and homeostatic model assessment of insulin resistance (HOMA-IR), a good proxy for IR, may represent an affordable predictive test which could be easily applied in routine clinical practice. We aimed to evaluate the diagnostic accuracy of HOMA-IR for NAFLD in T2DM and sought to estimate an optimal cut-off value for discriminating NAFLD from non-NAFLD cases. METHODS: We conducted a retrospective analysis of 56 well-controlled patients with T2DM (HbAc1<7%, on oral anti-diabetic and/or glucagon-like peptide-1 agonist treatment), who had at least one glucose and insulin level determined, and at least one hepatic imaging test (ultrasonography or computed tomography scanning). RESULTS: The prevalence of NAFLD was 73.2% (95% CI: 59.7-84.2) in our population. An association between HOMA-IR and NAFLD was found (OR 1.5; 95% CI: 1.03-2.1; p=0.033), independently of transaminases, fat percentage, BMI and triglyceride levels. The AUROC curve of HOMA-IR for identifying NAFLD was 80.7% (95% CI: 68.9-92.5). A value of HOMA-IR of 4.5 was estimated to be an optimal threshold for discriminating NAFLD from non-NAFLD cases. CONCLUSION: HOMA-IR is independently associated with the presence of NAFLD in adults with T2DM, and might potentially be applied in clinical practice as a screen for this condition.
