RESUMO
UK guidelines recommend liraglutide 3.0 mg in adults treated within specialist weight management services with BMI ≥35 kg/m2, prediabetes and high cardiovascular disease risk. We aimed to clinically evaluate liraglutide 3.0 mg in specialist weight management services. We evaluated liraglutide 3.0 mg in weight management services at Guys and St Thomas' NHS Foundation Trust. Objective body weight (BW) was measured at baseline and 4 months, allowing classification as 'responders' (≥5% BW reduction) and 'non-responders' (<5% BW reduction). One hundred and twenty-one patients were evaluated. At 4 months, 76.0% attended follow-up (82.6% responders, 17.4% non-responders); BW (-8.6 kg, 95%CI:-9.8, -7.4 kg), BMI (-3.2 kg/m2, 95%CI: -3.6, -2.8) and %-BW (-6.6%, IQR: -8.8%, -5.2%) significantly reduced. In responders, HbA1c reduced by -5.0 mmol/mol (IQR: -7.0. -4.0 mmol/mol). In responders BW continued to reduce up to 12 months (4 m: -10.2 kg, p < .0001; 6 m: -15.6 kg, p < .0001; 9 m: -16.5 kg, p < .0001; 12 m: -16.7 kg, p < .01). Those of Black African and Caribbean ethnicity experienced less BW loss than those of white ethnicity (4.12 kg, p = .017) and had a greater attrition rate. In adults with obesity and prediabetes who are treated within specialist weight management services, liraglutide 3.0 mg reduces BW and HbA1c. Those of Black African and Caribbean ethnicity experienced less BW reduction and greater attrition at 4 months. Further evaluation of the ethnic differences in response to obesity pharmacotherapy is required.

Cobalt (Co), copper (Cu), manganese (Mn), molybdenum (Mo), and zinc (Zn) are essential trace elements (ETEs) and important cofactors for intermediary metabolism or redox balance. These ETEs are crucial during pregnancy, their role on specific pregnancy outcomes is largely unknown. This prospective study (#NCT04010708) aimed to assess urinary levels of these ETEs in pregnancy and to evaluate their association with pregnancy outcomes. First trimester pregnant women of Porto and Lisbon provided a random spot urine sample, and sociodemographic and lifestyle data. Clinical data were obtained from clinical records. Urinary ETEs were quantified by inductively coupled plasma mass spectrometry (ICP-MS). A total of 635 mother:child pairs were included. Having urinary Zn levels above the 50th percentile (P50) was an independent risk factor for pre-eclampsia (PE) (aOR [95% CI]: 5.350 [1.044-27.423], p = 0.044). Urinary Zn levels above the P50 decreased the risk of small for gestational age (SGA) birth head circumference (aOR [95% CI]: 0.315 [0.113-0.883], p = 0.028), but it increased the risk SGA length (aOR [95% CI]: 2.531 [1.057-6.062], p = 0.037). This study may provide valuable information for public health policies related to prenatal nutrition, while informing future efforts to de-fine urinary reference intervals for ETEs in pregnant women.
RESUMO
INTRODUCTION: Obesity drives type 2 diabetes (T2DM) development. Laparoscopic adjustable gastric banding (LAGB) has lower weight reduction than other bariatric procedures. Liraglutide, a GLP-1 receptor agonist, improves weight and glycaemic control in patients with T2DM. This study aimed to determine the efficacy and safety of liraglutide 1.8 mg in participants undergoing LAGB. METHODS: GLIDE, a pilot randomised, double-blind, placebo-controlled trial, evaluated LAGB with either liraglutide 1.8 mg or placebo in participants with T2DM and obesity. Participants were randomised (1:1) to 6-months therapy post-LAGB, with further 6 months off-treatment follow-up. The primary outcome was change in HbA1c from randomisation to the end of treatment, secondary outcomes included body weight change. A sample size of 58 (29 per group) had 80% power to detect a 0.6% difference in HbA1c between groups. RESULTS: Twenty-seven participants were randomised to liraglutide (n = 13) or placebo (n = 14). Multivariate analysis showed no difference between placebo and liraglutide arms in HbA1c at 6 months (HbA1c:0.2 mmol/mol, -11.3, 11.6, p = 0.98) however, at 12 months HbA1c was significantly higher in the liraglutide arm (HbA1c:10.9 mmol/mol, 1.1, 20.6, p = 0.032). There was no difference between arms in weight at 6 months (BW:2.0 kg, -4.2, 8.1, p = 0.50), however, at 12 months weight was significantly higher in the liraglutide arm (BW:8.2 kg, 1.6, 14.9, p = 0.02). There were no significant differences in adverse events between groups. CONCLUSIONS: Our pilot data suggest no additional improvement in glycaemic control or BW with LAGB and liraglutide therapy. However, this trial was significantly underpowered to detect a significant change in the primary or secondary outcomes. Further trials are needed to investigate whether GLP-1 agonists, and particularly with more effective weekly agents (i.e. semaglutide or tirzepatide), are of benefit following metabolic surgery. CLINICAL TRIAL REGISTRATION: EudraCT number 2015-005402-11.

Objetivo: Avaliar o impacto da implantação do inventário rotativo diário na acurácia do estoque de medicamentos em um hospital público de médio porte. Metodologia: Trata-se de um estudo descritivo exploratório transversal que avaliou a implantação de um inventário rotativo de janeiro a julho de 2022. Foram selecionados 143 medicamentos que posteriormente foram inventariados, uma vez por mês, ao longo de sete meses. Esses medicamentos foram classificados segundo a curva ABC, XYZ e o grau de divergência em: baixo, médio e alto. Foi calculada a acurácia para cada grupo, ao longo dos meses analisados, e o Percentual de Mudança Relativa (PMR) para comparação entre o período inicial e final. Resultado: Houveum aumento de 64% na acurácia do estoque de medicamentos, sendo observada diferença entre os grupos ABC e XYZ. Em relação a curva ABC, o grupo A teve um aumento de 170%, o B de 358% e o C de 23% no mesmo período. Em relação a criticidade, o grupo Z foi o que teve maior acurácia, seguido dos grupos Y e X. Os medicamentos classificados como de alta taxa de divergência tiveram redução de 80% e o de baixa 25% após implantação do inventário. Conclusão: A implantação do inventário rotativo aumentou a acurácia do estoque de medicamentos ao longo dos meses avaliados. Essa ferramenta pode ser uma estratégia utilizada na melhoria do gerenciamento de estoque de medicamentos. (AU)
Objective: To evaluate the impact of implementing a daily rotating inventory on the accuracy of medicines stocks in a medium-sized public hospital. Methodology: This is a cross-sectional exploratory descriptive study that evaluated the implementation of a rotating inventory from January to July 2022. 143 medicines were selected and subsequently inventoried once a month over seven months. These medicines were classified according to the ABC, XYZ curve and the degree of divergence in low, medium and high. Accuracy was calculated for each group, over the analyzed months, and the Relative Percentage Change (RPC) for comparison between the initial and final period. Result: There was a 64% increase in the accuracy of medicines inventory, with a difference being observed between the ABC and XYZ groups. Regarding the ABC curve, group A had an increase of 170%, group B 358% and group C 23% in the same period. Regarding criticality, group Z had the highest accuracy, followed by groups Y and X. Medicines classified as having a high rate of divergence had a reduction of 80% and the low rate of 25% after implementation of the inventory. Conclusion: The implementation of the rotating inventory increased the accuracy of the medicines stock over the evaluated months. This tool can be a strategy used to improve medicine inventory management. (AU)
RESUMO
Obesity is a significant public health concern which is implicated in cardiometabolic disease, mechanical complications and psychiatric sequelae. BMI is currently used for diagnosis; however, it has limited sensitivity for adiposity in certain circumstances. This has led to the development of risk stratification tools like the Edmonton Staging criteria and the Kings Obesity Staging Criteria: these facilitate and guide comprehensive obesity-related complication assessment. Healthcare professionals working within obesity clinics should adopt evidence-based communication strategies, including shared decision-making, motivational interviewing, and realistic goal setting. It is also vital to avoid weight-stigmatising terminology in all aspects of care, as this can negatively impact patients. Primary care plays an essential part in obesity care and should work to promptly identify cases, initiate treatment and forward on to specialist services where appropriate. Clinical evaluation of the patient living with obesity should take a holistic approach and involve input from bariatric physicians, dietitians, psychologists, and bariatric surgeons, wider members of the multi-disciplinary team should be involved where needed. Clinicians should take a detailed history, examination and order laboratory tests to investigate for complications. Overall, with appropriate evaluation, these assessments can guide patient management and facilitate long-term improvement in health.

Introduction Heart failure with reduced ejection fraction (HFrEF) patients are prone to developing ventricular arrhythmias. In the PARADIGM-HF trial, sacubitril-valsartan (SV) showed a reduction in the composite endpoint of death and HF hospitalization in HFrEF patients; subgroup analysis of this trial revealed a reduction in both sudden death and deaths from worsening HF. The mechanism by which SV may affect the incidence of ventricular arrhythmias is currently under debate, and the literature provides conflicting results. The aim of our study was to evaluate the potential antiarrhythmic effect of this drug in patients with HFrEF carrying an implantable cardiac defibrillator (ICD) or a cardiac resynchronization therapy with a defibrillator (CRT-D). Methods This was a single-center, observational and retrospective study. Inclusion criteria were implantation of an ICD or CRT-D device between 2009 and 2019, age ≥18 years, left ventricle ejection fraction (LVEF) ≤40%, New York Heart Association (NYHA) functional class ≥II, and treatment with an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker for at least 12 months, followed by replacement with SV. Exclusion criteria were NYHA class IV, frequent alterations in chronic medication for HFrEF, and implantation of an ICD or CRT-D after the introduction of SV. The primary outcome was the occurrence of ventricular arrhythmias in the form of appropriate device shocks, ventricular fibrillation, or ventricular tachycardia. The comparisons were performed between two periods of time (12 months before and 12 months after SV) in the same group of patients. Results Fifty-four patients met the inclusion criteria. The mean age was 69.5 ± 1.65 years, and 74.1% of patients were male. The number of patients experiencing appropriate shocks was significantly lower after SV initiation (2% vs. 18%; p=0.016). The percentage of VT (13 vs. 20%; p=0.549) and VF episodes (4% vs. 13% for VF; p=0.289) were also lower, but these differences were not statistically significant. There were no significant differences in the value of NT-proBNP (1128 vs. 775 pg/mL; p=0.858), LVEF (28.4 vs. 29.6%; p=0.315), and left ventricular end-diastolic diameter (65.0 vs. 66.0 mm; p=0.5492). Conclusion SV seems to reduce the risk of arrhythmic events requiring appropriate shock therapy.
RESUMO
The aims of this study were to characterize the exposure of pregnant women living in Portugal to 3-phenoxybenzoic acid (3-PBA) and to evaluate the association of this exposure with maternal outcomes and newborn anthropometric measures. We also aimed to compare exposure in summer with exposure in winter. Pregnant women attending ultrasound scans from April 2018 to April 2019 at a central hospital in Porto, Portugal, were invited to participate. Inclusion criteria were: gestational week between 10 and 13, confirmed fetal vitality, and a signature of informed consent. 3-PBA was measured in spot urine samples by gas chromatography with mass spectrometry (GC-MS). The median 3-PBA concentration was 0.263 (0.167; 0.458) µg/g creatinine (n = 145). 3-PBA excretion was negatively associated with maternal pre-pregnancy body mass index (BMI) (p = 0.049), and it was higher during the summer when compared to winter (p < 0.001). The frequency of fish or yogurt consumption was associated positively with 3-PBA excretion, particularly during the winter (p = 0.002 and p = 0.015, respectively), when environmental exposure is low. Moreover, 3-PBA was associated with levothyroxine use (p = 0.01), a proxy for hypothyroidism, which could be due to a putative 3-PBA-thyroid hormone antagonistic effect. 3-PBA levels were not associated with the anthropometric measures of the newborn. In conclusion, pregnant women living in Portugal are exposed to 3-PBA, particularly during summer, and this exposure may be associated with maternal clinical features.
RESUMO
Parathyroid carcinoma is one of the least common endocrine malignancies and accounts for approximately 1% of all patients with primary hyperparathyroidism. A systematic review of peer-reviewed literature published between January 2000 and March 2022 via Medline, Embase, Cochrane Central Register of Controlled Trials, EudraCT, ClinicalTrials.gov, CINAHL and SCOPUS was conducted. Manuscripts were eligible if they included data on adult non-pregnant populations with parathyroid carcinoma. No restrictions regarding interventions, comparators or duration of follow-up were imposed. Single case reports, reviews or meta-analyses were excluded. Outcomes of interest were molecular pathogenesis, clinical presentation, differential diagnosis, treatment, follow-up and overall survival. Study quality was evaluated using the Newcastle-Ottawa Scale for observational studies. This review included 75 studies from 17 countries, reporting on more than 3000 patients with parathyroid carcinoma. CDC73 mutation has been recognised as playing a pivotal role in molecular pathogenesis. Parathyroid carcinoma typically presents with markedly increased calcium and parathyroid hormone levels. The most frequently described symptoms were bone and muscle pain or weakness. En bloc resection remains the gold standard for the surgical approach. The 5-year overall survival ranged from 60 to 93%, with resistant hypercalcaemia a significant cause of mortality. Emerging evidence indicating that targeted therapy, based on molecular biomarkers, presents a novel treatment option. The rarity of PC and need for personalised treatment warrant multidisciplinary management in a 'centre of excellence' with a track record in PC management.

Resumo Objetivo Verificar a prevalência e fatores associados ao uso de medicamentos potencialmente inapropriados (MPI) pela população idosa e a concordância entre duas metodologias de avaliação no contexto da Atenção Primária à Saúde (APS). Método Estudo observacional transversal. Foi estimada a prevalência de pessoas idosas que utilizam MPI e fatores associados. Inicialmente foi calculada a frequência de medicamentos, entre os utilizados, considerados MPI. A classificação como MPI foi pelos Critérios de Beers 2019 e Consenso Brasileiro de Medicamentos Potencialmente Inapropriados para idosos (CBMPI) 2016. Também avaliou-se a concordância entre as duas classificações. Foram construídos modelos de regressão logística multivariada para avaliação da associação pelo Odds Ratio (OR), e calculado Kappa para concordância entre os dois critérios de classificações. Resultados A prevalência de pessoas idosas que usavam MPI foi 32,9% pelos Critérios de Beers e 27,6% pelo CBMPI. Associações estatisticamente significativas (p<0,001) ao uso de medicamentos inapropriados, pelos Critérios de Beers foram: relato de diabetes (OR=1,96), depressão (OR=2,25) e polifarmácia (OR=4,11). Pessoas idosas satisfeitas com a própria saúde tiveram menor chance de usarem MP, em ambas classificações, Critérios Beers (OR=0,02) e CBMPI (OR=0,09). A concordância entre as classificações foi muito boa (k=0,75, p<0,001). Conclusão Foram associados ao uso de MPI relato de diabetes e depressão, polifarmácia e satisfação negativa com a saúde. As associações foram semelhantes entre as duas classificações, indicando que ambas são pertinentes na identificação do uso de MPI em pessoas idosas usuárias da APS.
Abstract Objective To verify the prevalence of potentially inappropriate medications (PIM) in use and possible associated factors in older adults and the agreement between two assessment tool in Primary Health Care (PHC) contex Methods Cross-sectional study. The prevalence of older adults in use of PIM and associated factors were estimated. First of all was calculated the frequency of drugs, among those used, considered PIM. Classification as PIM was based on the 2019 Beers Criteria and the 2016 Brazilian Consensus on Potentially Inappropriate Medications 2016 (BCPIM) for the older adults. The agreement between the two classifications was also evaluated. Multivariate logistic regression models were estimated. Association was evaluated by Odds Ratio (OR). Kappa was calculated for agreement between both classifications. Results The prevalence of older adults using MPI was 32.9%, according to Beers Criteria and 27.6% according to the BCPIM. The reports of diabetes (OR=1.96), depression (OR=2.25) and polypharmacy (OR=4.11) were associated (p<0.001) with the use of inappropriate medication, according to the Beers Criteria. Older adults who were very satisfied with their own health were less likely to use inappropriate medication both according to the Beers Criteria (OR=0.02) and the BCPIM (OR=0.09). Agreement between classifications was considered good (k=0.75, p<0.001). Conclusion Reports of diabetes and depression, polypharmacy and negative self-rated health and satisfaction were associated with PIM's use. The associations were similar between the two classifications, indicating that both are relevant in identifying PIM use in older adults in the context of PHC.

Background: An association between thyroid disease and tinnitus has been described previously but further longitudinal, population-based studies are limited. Objective: To investigate the incidence of tinnitus in patients with hyperthyroidism in a national sample, and to identify risk level and associated factors for tinnitus in hyperthyroidism patients. Design: Retrospective cohort study. Patient data were collected from the Longitudinal Health Insurance Database (LHID 2000), which includes national claims data of patient expenditures for admissions or ambulatory care from 1996 to 2011. Setting: Taiwan hospitals and clinics providing healthcare nationwide. Participants: Patients aged 20 years and older with newly diagnosed hyperthyroidism (ICD-9-CM code 242) between 2000-2010 were selected as the study cohort. Hyperthyroidism patient cohort were identified from the LHID2000. Those with tinnitus history (ICD-9-CM code 388.3) before the index date (first hyperthyroidism diagnosis), younger than 20 years, and with incomplete demographic data were excluded. The non-hyperthyroidism cohort included patients with no history of hyperthyroidism and no documented tinnitus. Main Outcomes and Measures: Incidence of tinnitus was the primary outcome. Baseline demographic factors and comorbidities possibly associated with tinnitus, including age, sex, and comorbidities of hearing loss, vertigo, insomnia and anxiety, were retrieved from the LHID 2000. Patients were followed until end of 2011. Results: During the study period, 780 (4.9%) hyperthyroidism patients and 2007 (3.2%) non-hyperthyroidism controls developed tinnitus. Incidence rate of tinnitus in the hyperthyroidism cohort was significantly higher in hyperthyroidism cohort (7.86 vs. 5.05 per 1000 person-years) than that in non-hyperthyroidism cohort. A higher proportion of patients with hyperthyroidism had comorbid insomnia (45.1% vs. 30.9%) and anxiety (14.0% vs. 5.73%) than those without hyperthyroidism. After adjusting for age, gender and comorbidities (vertigo, insomnia, anxiety, hearing loss), hyperthyroidism patients had 1.38-fold higher risk of tinnitus (95% CI = 1.27-1.50) than those without hyperthyroidism. Conclusions: This large population-based study suggests patients with diagnosed hyperthyroidism was more prone to develop tinnitus. Our findings suggest evaluation for comorbid vertigo, insomnia, anxiety and/or hearing loss may identify patients who are at high risk of developing tinnitus in patients with hyperthyroidism.

PURPOSE OF REVIEW: The aim of this review is to outline the obesity physician's role in managing patients with severe obesity with a particular emphasis on bariatric surgery candidates. RECENT FINDINGS: Obesity is a chronic, relapsing and progressive disease. Scoring systems that evaluate the severity of obesity based on the clinical assessment, rather than the Body Mass Index, are a valuable tool. The clinical assessment should explore the underlying contributors for weight gain and screen for obesity-related complications. Bariatric surgery remains the most effective management approach for severe and complex obesity. Nevertheless, pharmacotherapy and other non-surgical approaches play an important role. The bariatric-metabolic physician's role is paramount in delivering effective care to patients with obesity. The multiple complications of patients with clinically severe obesity highlight the complexity of their management and reinforce the need for adequate assessment and long-term follow-up to ensure optimal clinical outcomes.

The role of milk and dairy products in supplying iodine to pregnant women is unknown in Portugal. The aim of this study was to evaluate the association between milk and dairy product consumption and the iodine status of pregnant women in the IoMum cohort of the Oporto region. Pregnant women were recruited between 10 and 13 weeks of gestation, when they provided a spot urine sample and information on lifestyle and intake of iodine-rich foods. Urinary iodine concentration (UIC) was determined by inductively coupled plasma MS. A total of 468 pregnant women (269 iodine supplement users and 199 non-supplement users) were considered eligible for analysis. Milk (but not yogurt or cheese) intake was positively associated with UIC, in the whole population (P = 0·02) and in the non-supplement users (P = 0·002), but not in the supplement users (P = 0·29). In non-supplement users, adjusted multinomial logistic regression analysis showed that milk consumption <3 times/month was associated with a five times increased risk of having UIC < 50 µg/l when compared with milk consumption ≥2 times/d (OR 5·4; 95 % CI 1·55, 18·78; P = 0·008). The highest UIC was observed in supplement users who reported consuming milk once per d (160 µg/l). Milk, but not yogurt or cheese, was positively associated with iodine status of pregnant women. Despite the observed positive association, daily milk consumption may not be sufficient to ensure adequate iodine intake in this population.

Lack of knowledge about iodine has been suggested as a risk factor for iodine deficiency in pregnant women, but no studies have addressed this issue in Portugal. So, the aim of this study was to investigate iodine knowledge among Portuguese pregnant women and its association with iodine status. IoMum, a prospective observational study, included 485 pregnant women recruited at Centro Hospitalar e Universitário de S. João, Porto, between the 10th and 13th gestational weeks. Partial scores for knowledge on iodine importance, on iodine food sources or on iodised salt were obtained through the application of a structured questionnaire. Then, a total iodine knowledge score was calculated and grouped into low, medium and high knowledge categories. Urinary iodine concentration (UIC) was measured in spot urine samples by inductively coupled plasma MS. Of the pregnant women, 54 % correctly recognised iodine as important to neurocognitive development, 32 % were unable to identify any iodine-rich food and 71 % presented lack of knowledge regarding iodised salt. Of the women, 61 % had a medium total score of iodine knowledge. Knowledge on iodine importance during pregnancy was positively associated with iodine supplementation and also with UIC. Nevertheless, median UIC in women who correctly recognised the importance of iodine was below the cut-off for adequacy in pregnancy (150 µg/l). In conclusion, knowledge on iodine importance is positively associated with iodine status. Despite this, recognising iodine importance during pregnancy may not be sufficient to ensure iodine adequacy. Literacy-promoting actions are urgently needed to improve iodine status in pregnancy.

BACKGROUND/AIMS: Overall, 2-13% of patients with thyroid cancer develop bone metastases (BM). In addition to decreased survival, patients with BM may present skeletal-related events (SRE) that impair the quality of life. Our objectives were to characterize clinical features, treatment approaches, and outcomes of patients with thyroid cancer and BM. MATERIAL AND METHODS: We identified patients diagnosed with thyroid carcinoma of follicular origin and BM followed at the Instituto Português de Oncologia de Lisboa Francisco Gentil (IPOLFG), Lisbon, Portugal, from 1991 to 2017. SRE were defined as the need for bone irradiation, bone surgery, spinal cord compression, or pathologic fractures. RESULTS: The final cohort consisted of 86 patients, with a median follow-up time of 54 months (IQR 22.8-82.8), mainly women (67.4%), and a median age of 64 years (IQR 53.6-71.2). BM was the initial presentation of thyroid cancer in 36.0% of the patients. Bone involvement was multiple in 59.3% of the cases. Papillary carcinoma was the most frequent histological type, present in 47.7% of the patients, of which 56.1% presented the follicular variant. SRE were found in 76.7% of the patients. The most frequent SRE was radiotherapy (66.3%). Treatment with bisphosphonates was initiated in 19.8% of the patients. The 5-year specific survival was 60%, whereas the 10-year specific survival decreased to 50%. There were no differences in 5- or 10-year specific survival regarding gender, the occurrence of SRE, or histological type. However, patients with initial radioiodine non-avid lesions had a lower 5- and 10-year specific survival (p = 0.002). DISCUSSION: The high frequency of patients with SRE was notable. The follicular variant of papillary thyroid cancer was the variant most commonly associated with BM, reflecting a more similar behavior to follicular carcinoma than the classic variant.
RESUMO
INTRODUCTION: Nyssomyia intermedia is an important vector of American cutaneous leishmaniasis. METHODS: Sand flies were captured in a Shannon trap and after landing on human collectors and retrieved monthly. Nocturnal activity was estimated using a log-linear model. RESULTS: Peak sand fly collection in the Shannon trap occurred in summer and winter, and peak fly collection on humans occurred in spring and summer. CONCLUSIONS: Ny. intermedia was captured in both the hottest and coldest months, indicating its adaptability to different seasons and the possibility of disease transmission at any time of the year in Campus Fiocruz Mata Atlântica, Brazil.
