RESUMO

Metabolic/bariatric surgery as a treatment for obesity and related diseases, such as type 2 diabetes mellitus (T2DM), has been increasingly recognised in recent years. However, compared with conventional pharmacologic therapy, the long-term effect (≥ 5 years) of metabolic surgery in T2DM patients is still unclear. This study aimed to evaluate the diabetes remission rate, incidence of diabetic microvascular complications, incidence of macrovascular complications, and mortality in T2DM patients who received metabolic surgery versus pharmacologic therapy more than 5 years after the surgery. Searching the database, including PubMed, Embase, Web of Science, and Cochrane Library from the inception to recent (2024), for randomised clinical trials (RCTs) or cohort studies comparing T2DM patients treated with metabolic surgery versus pharmacologic therapy reporting on the outcomes of the diabetes remission rate, diabetic microvascular complications, macrovascular complications, or mortality over 5 years or more. A total of 15 articles with a total of 85,473 patients with T2DM were eligible for review and meta-analysis in this study. There is a significant long-term increase in diabetes remission for metabolic surgery compared with conventional medical therapy in the overall pooled estimation and RCT studies or cohort studies separately (overall: OR = 4.58, 95% CI: 1.89-11.07, P < 0.001). Significant long-term decreases were found in the pooled results of microvascular complications incidence (HR = 0.57, 95% CI: 0.41-0.78, P < 0.001), macrovascular complications incidence (HR = 0.59, 95% CI: 0.50-0.70, P < 0.001) and mortality (HR = 0.53, 95% CI: 0.53-0.79, P = 0.0018). Metabolic surgery showed more significant long-term effects than pharmacologic therapy on diabetes remission, macrovascular complications, microvascular complications incidence, and all-cause mortality in patients with T2DM using currently available evidence. More high-quality evidence is needed to validate the long-term effects of metabolic surgery versus conventional treatment in diabetes management.

RESUMO

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a common condition that causes irreversible airway obstruction. Fatigue and exertional dyspnoea, for example, have a detrimental impact on the patient's daily life. Current research has revealed the need to empower the patient, which can result in not only educated and effective decision-making, but also a considerable improvement in patient satisfaction and treatment compliance. The current study aimed to investigate the perspectives and requirements of people living with COPD to possibly explore new ways to manage their disease. METHODS: Adults with COPD from 8 European countries were interviewed by human factor experts to evaluate their disease journey through the gathering of information on the age, performance, length, and impact of diagnosis, symptoms progression, and family and friends' reactions. The assessment of present symptoms, services, and challenges was performed through a 90-min semi-structured interview. To identify possible unmet needs of participants, a generic thematic method was used to explore patterns, themes, linkages, and sequences within the data collected. Flow charts and diagrams were created to communicate the primary findings. Following analysis, the data was consolidated into cohesive insights and conversation themes relevant to determining the patient's unmet needs. RESULTS: The 62, who voluntarily accepted to be interviewed, were patients (61% females, aged 32-70 years) with a COPD diagnosis for at least 6 months with stable symptoms of different severity. The main challenges expressed by the patients were the impact on their lifestyle, reduced physical activity, and issues with their mobility. About one-fourth had challenges with their symptoms or medication including difficulty in breathing. Beyond finding a cure for COPD was the primary goal for patients, their main needs were to receive adequate information on the disease and treatments, and to have adequate support to improve physical activity and mobility, helpful both for patients and their families. CONCLUSIONS: These results could aid in the creation of new ideas and concepts to improve our patient's quality of life, encouraging a holistic approach to people living with COPD and reinforcing the commitment to understanding their needs.

RESUMO

Nurses in the emergency department often encounter patients exhibiting signs of aggressive behavior. Nurses need to know the pharmacologic treatment appropriate for the patient scenario to ensure safety for the patient and the emergency department team. This case review examines 4 common scenarios where a patient exhibits aggressive behavior. After each case review is a discussion about the appropriate pharmacologic therapy for that patient. The cases portrayed are fictional but based on experience and previous observations.

RESUMO

Hepatic encephalopathy (HE) is a potentially reversible neurocognitive complication of cirrhosis. It has been reported in at least 30% of patients with cirrhosis and imposes a significant economic burden on caregivers and the healthcare system. Ammonia has been recognized as the culprit in HE development, and all the currently approved treatments mostly act on this toxin to help with HE resolution. After a brief overview of HE characteristics and pathophysiology, this review explores the current accepted treatments for this debilitating complication of cirrhosis. This is followed by an overview of the novel available therapies and a brief focus on future treatment modalities for HE.

RESUMO

BACKGROUND: Agitated delirium is common and highly distressing. Medications are often needed to reduce agitation, but it is unclear what the desired level of sedation is. This study assessed personalized sedation goals (PSGs) and their predictors for patients in a delirium clinical trial and in clinical vignettes. METHODS: This was a preplanned secondary analysis of a double-blind randomized clinical trial examining the sedative effect of chlorpromazine and/or haloperidol in patients with agitated delirium. At the baseline, caregivers and nurses were independently asked to select the PSG for the trial patient from 5 choices corresponding to Richmond Agitation Sedation Scale (RASS) scores of 0 or higher (no sedation), -1 to -2, -3, -4, and -5 (deep sedation). Respondents also selected a PSG for 6 vignettes that differed by the level of agitation, ability to communicate, and survival. RESULTS: Forty-two caregivers and 39 nurses answered questions regarding PSGs. For the trial patient, caregivers preferred RASS scores of -1 to -2 most often (36%), whereas nurses preferred an RASS score of -3 most often (51 %). Caregivers were significantly more likely than nurses to choose lighter sedation (odds ratio [OR], 4.8; P = .01) despite reporting greater delirium-related distress (P = .0006). Patients were undersedated 33% to 53% of the time and oversedated 0% to 15% of the time according to the PSG response criteria. In the case vignettes, deeper sedation was preferred by nurses (P < .0001) and for patients who were unable to communicate (OR, 3.1-4.4; P < .0001) and had a shorter life expectancy (OR, 1.7; P = .002). CONCLUSIONS: Caregivers often preferred lighter sedation than nurses. Many patients were undersedated in comparison with caregivers' PSGs, and this highlights room for improvement. LAY SUMMARY: In the last days of life, many patients with cancer develop delirium and become restless/agitated; this can be highly distressing. Caregivers and physicians alike are often concerned about the use of sedatives for agitated delirium and try to find a balance between maximizing comfort and maintaining communication. This study examined the concept of a personalized sedation goal for setting an individualized target for the level of sedation. Caregivers often preferred lighter sedation than nurses. Many patients were undersedated in comparison with caregivers' stated goals, and this highlights room for improvement.

RESUMO

BACKGROUND: Hypothalamic obesity causes unrelenting weight gain for childhood brain tumor survivors. No single therapy has proven effective for treatment. We aimed to evaluate effectiveness of long-term methylphenidate therapy on body mass index (BMI) change in children with hypothalamic obesity. METHODS: A retrospective analysis included children with a history of brain tumor and hypothalamic obesity receiving methylphenidate (10-60 mg/day) for hypothalamic obesity. Subjects were evaluated for BMI trajectory before and after methylphenidate start. Given that z-scores can be skewed in severely obese children, we calculated BMI as a percent of the BMI at the 95th percentile for the child's age and gender (BMI% 95th). RESULTS: Twelve patients with hypothalamic obesity completed methylphenidate therapy for at least 6 months (median 3.1 years, range 1.0-5.8 years). All subjects had a suprasellar tumor (nine [75%] with craniopharyngioma) and pituitary dysfunction. Pretreatment median BMI percent of the 95th percentile was 125.6% (interquartile range [IQR] 25-75: 115.3-138.3%) with BMI z-score of 2.4 (IQR 25-75: 2.1-2.6). Following methylphenidate treatment, there was a 69.9% reduction in the median slope of BMI change. Eleven of 12 patients (92%) had a reduction in the slope of their BMI change on methylphenidate treatment. Postmethylphenidate median BMI percent of the 95th percentile decrease to 115.2% (IQR 25-75: 103.6-121.2%) with median BMI z-score of 2.1 (IQR 25-75: 1.8-2.2). Mild side effects were noted in six patients. CONCLUSIONS: Methylphenidate use reduced and sustained BMI change in children with hypothalamic obesity. Stimulant therapy is an effective first-line agent for treatment of hypothalamic obesity.

RESUMO

After an episode of myocardial infarction (MI), patients remain at risk for recurrent ischemic events, heart failure (HF), and sudden death. Post-MI patients with left ventricular systolic dysfunction (LVSD) have an even greater risk of mortality and morbidity. Randomized clinical trials that included post-MI patients with LVSD have demonstrated that pharmacologic therapies aimed at preventing post-MI remodeling with neurohormonal antagonists can significantly improve short- and long-term outcomes, including death, reinfarction, and worsening HF. Recent trials have also demonstrated benefits in terms of cardiovascular event reduction with effective antithrombotic therapies and cholesterol-lowering agents in post-MI setting, especially in patients at very high risk such as those with LVSD. This paper reviews clinical trials that included post-MI patients with LVSD, with or without signs and symptoms of HF, assessing the efficacy of established and emerging pharmacological therapies.

RESUMO

OBJECTIVES: Although cross-sectional studies have shown that ankylosing spondylitis-specific factors correlate with depressive symptom severity, the association of these factors over time is unresolved. We examined the demographic and clinical factors associated with longitudinal depressive symptom severity in AS patients. METHODS: We analyzed sociodemographic, clinical, behavioral and medication data from 991 patients from the Prospective Study of Outcomes in Ankylosing spondylitis cohort, and measured depression severity with the Center for Epidemiological Studies Depression (CES-D) Scale administered at approximately 6-month visit intervals. Multivariable longitudinal negative binomial regression models were conducted using generalized estimating equation modeling to assess the demographic, clinical, and medication-related factors associated with depression severity by CES-D scores over time. RESULTS: The median baseline CES-D score (possible range 0-60) was 10.0 (interquartile range = 5, 17). In longitudinal multivariable analyses, higher CES-D scores were associated with longitudinal smoking, greater functional impairment, greater disease activity, self-reported depression, and poor global health scores. Marital status (e.g., being married) was associated with lower CES-D. Adjusted mean CES-D scores in our model decreased over time, with a significant interaction between time and gender observed. CONCLUSION: This study identified longitudinal clinical factors such as greater disease activity, greater functional impairment, and poor global health to be associated with longitudinal depression severity. These factors are potentially modifiable and may help manage depressive symptoms in AS.

RESUMO

Background and Objectives: Currently, one in eight people over the age of 65 have dementia, and approximately 75% of caregiving is provided by volunteer family members with little or no training. This study aimed to quantify points of stress for home-based caregivers with the aim of reducing stress for them while concurrently supporting quality of life for the people with dementia whom they cared for. The overreaching purpose was to increase our knowledge of the caregiver stress burden and explore potential technologies and behaviors to ease it. Materials and Methods: We interviewed home-based and professional caregivers regarding causes of emotional and physical stress and methods they used to alleviate it. Results: This study found that: (1) dementia symptoms created a burden of stress for home-based caregivers primarily in the areas of medication management, memory loss, hygiene care and disruptive behaviors; (2) home-based caregivers identified "finding available resources" as the most important source of stress relief; (3) a minority of home-based caregivers possessed a resource network and knew how to find resources but all professional caregivers were able to find resources and support; (4) home-based caregivers combated dementia symptoms with positive distractions and human touch with little use of technology, since it was mostly unknown; and 5) facility-based caregivers were knowledgeable and readily used dementia-based technology. Conclusion: Since professional caregivers have access to technological resources that our home-based caregivers lack, one might logically conclude that we should transfer technology used by professionals to those with dementia. However, great caution needs to be in place before we take that step. Successful technology should address the human experience as home-based caregivers try to use new technologies. Human-centric technology addresses the needs of both people with dementia and the home-based caregiver.

RESUMO

Machado-Joseph disease (MJD), also known as Spinocerebellar Ataxia type 3 (SCA3), is the most common autosomal dominant ataxia worldwide. MJD integrates a large group of disorders known as polyglutamine diseases (polyQ). To date, no effective treatment exists for MJD and other polyQ diseases. Nevertheless, researchers are making efforts to find treatment possibilities that modify the disease course or alleviate disease symptoms. Since neuroimaging studies in mutation carrying individuals suggest that in nervous system dysfunction begins many years before the onset of any detectable symptoms, the development of therapeutic interventions becomes of great importance, not only to slow progression of manifest disease but also to delay, or ideally prevent, its onset. Potential therapeutic targets for MJD and polyQ diseases can be divided into (i) those that are aimed at the polyQ proteins themselves, namely gene silencing, attempts to enhance mutant protein degradation or inhibition/prevention of aggregation; and (ii) those that intercept the toxic downstream effects of the polyQ proteins, such as mitochondrial dysfunction and oxidative stress, transcriptional abnormalities, UPS impairment, excitotoxicity, or activation of cell death. The existence of relevant animal models and the recent contributions towards the identification of putative molecular mechanisms underlying MJD are impacting on the development of new drugs. To date only a few preclinical trials were conducted, nevertheless some had very promising results and some candidate drugs are close to being tested in humans. Clinical trials for MJD are also very few to date and their results not very promising, mostly due to trial design constraints. Here, we provide an overview of the pharmacological therapeutic strategies for MJD studied in animal models and patients, and of their possible translation into the clinical practice.

RESUMO

PURPOSE OF REVIEW: The aim of this study is to characterize, diagnose, evaluate, and treat severe childhood asthma. RECENT FINDINGS: Understanding the occurrence of the physiologic and clinical presentations of childhood severe asthma, the treatment and response may be predicted by biomarkers, but the patient's response is highly variable. The onset of severe asthma occurs early and is primarily predicted by severity of viral infection and coexistence of the atopic state.

RESUMO

DESCRIPTION OF SITUATION: Stargardt disease, an inherited macular dystrophy caused by mutations in the ABCA4 gene encoding a retinal transporter protein, is the most prevalent form of macular degeneration in children. Patients with Stargardt disease develop severe vision loss within their first or second decades of life, which progresses to irreversible decreased visual acuity in almost all cases. Presently, there are no standard treatments for Stargardt disease. However, encouraging progress has been made in the development of innovative approaches to preventing vision loss in Stargardt patients. OBJECTIVE OF STUDY: Among the promising treatment candidates include ALK-001, fenretinide, and A1120 as pharmacological agents to modulate the visual cycle, StarGenTM as a vector for supplementation of a functional ABCA4 gene, and stem-cell transplantation of hESC-RPE cells for regeneration of the retinal pigment epithelium. This study aims to systematically review and summarize evidence concerning the most up-to-date developments in pharmacologic, gene, and stem-cell therapies as novel therapeutic strategies to improve vision for patients with Stargardt disease.

RESUMO

PURPOSE OF REVIEW: Chronic pain is usually managed by various pharmacotherapies after exhausting the conservative modalities such as over-the-counter choices. The goal of this review is to investigate current state of opioids and non-opioid medication overuse that includes NSAIDs, skeletal muscle relaxants, antidepressants, membrane stabilization agents, and benzodiazepine. How to minimize medication overuse and achieve better outcome in chronic pain management? RECENT FINDINGS: Although antidepressants and membrane stabilization agents contribute to the crucial components for neuromodulation, opioids were frequently designated as a rescue remedy in chronic pain since adjunct analgesics usually do not provide instantaneous relief. The updated CDC guideline for prescribing opioids has gained widespread attention via media exposure. Both patients and prescribers are alerted to respond to the opioid epidemic and numerous complications. However, there has been overuse of non-opioid adjunct analgesics that caused significant adverse effects in addition to concurrent opioid consumption. It is a common practice to extrapolate the WHO three-step analgesic ladder for cancer pain to apply in non-cancer pain that emphasizes solely on pharmacologic therapy which may result in overuse and escalation of opioids in non-cancer pain. There has been promising progress in non-pharmacologic therapies such as biofeedback, complementary, and alternative medicine to facilitate pain control instead of dependency on pharmacologic therapies. This review article presents the current state of medication overuse in chronic pain and proposes precaution to balance the risk and benefit ratio. It may serve as a premier for future study on clinical pathway for comprehensive chronic pain management and reduce medication overuse.

RESUMO

PURPOSE OF REVIEW: This review aims to summarize the growing body of literature of HF with reduced ejection fraction (HFrEF) and preserved ejection fraction (HFpEF) with a focus on recent pharmacologics. RECENT FINDINGS: HFrEF continues to be more widely investigated than HFpEF. Ivabradine and combinatorial treatment with sacubitril and valsartan are promising newly approved therapies. Other experimental therapies have emerged, which include Serelaxin, Empagliflozin, Neuregulin, and Omecamtive mecarbil, among others. These drugs need to continue to be investigated for safety and efficacy. We predict ivabradine and combinatorial treatment with sacubitril-valsartan to develop as a widespread therapy. New therapies should be aimed at treating HFpEF or target the cardiomyocyte itself.

RESUMO

Quantum advances have occurred in the field of human genetics in the six decades since Watson and Crick expressed their "wish to suggest a structure for the salt of deoxyribose nucleic acid." These culminated with the human genome project, which has opened up myriad possibilities, including that of individualized genetic medicine, the ability to deliver medical advice, management, and therapy tailored to an individual's genetic blueprint. Advances in genetic diagnostic capabilities have been rapid, to the point where the genome can be sequenced for several thousand dollars. Crucially, it has facilitated the identification of targets for "precision" treatments to combat genetic diseases at their source. This manuscript will review the innovative, pathogenesis-based therapies that are revolutionizing management of skeletal dysplasias, giving patients and families new options and outcomes. © 2016 Wiley Periodicals, Inc.

RESUMO

Baroreflex activation therapy (BAT) produces a central inhibition of cardiac sympathetic outflow and, concomitantly, an increased cardiac vagal activity via a physiological reflex pathway. In a pilot study in 11 patients with NYHA class III heart failure (HF), BAT produced a persistent significant reduction of muscle sympathetic nerve activity over a 21-month follow-up and a dramatic decrease in the number and length of hospitalizations. In a multinational, prospective, randomized, parallel-controlled, clinical trial in 146 NYHA functional class III HF, BAT produced a significant N-terminal pro-brain natriuretic peptide reduction (p = 0.02). This was associated with a trend toward few in hospital days for HF. BAT might become a powerful tool to manipulate autonomic alterations of HF at their origin and thus profoundly affect advanced HF patient prognosis.

RESUMO

Atrial fibrillation (AF) is the most frequently encountered arrhythmia. Prevalence increases with advancing age and so as its associated comorbidities, like heart failure. Choice of pharmacologic therapy depends on whether the goal of treatment is maintaining sinus rhythm or tolerating AF with adequate control of ventricular rates. Antiarrhythmic therapy and conversion of AF into sinus rhythm comes with the side effect profile, and we should select best antiarrhythmic therapy, individualized to the patient. New antiarrhythmic drugs are being tested in clinical trials. Drugs that target remodeling and inflammation are being tested for their use as prevention of AF or as upstream therapy.

RESUMO

We analyzed long-term sustainability of improved blood Phenylalanine (Phe) control and changes to dietary Phe tolerance in 11 patients (1 month to 16 years), with various forms of primary PAH deficiency (classic, moderate, severe phenylketonuria [PKU], mild hyperphenylalaninemia [HPA]), who were treated with 15-20mg/kg/d Sapropterin-dihydrochloride during a period of 13-44 months. 7/11 patients had a sustainable, significant reduction of baseline blood Phe concentrations and 6 of them also had an increase in mg/kg/day Phe tolerance. In 2 patients with mild HPA, blood Phe concentrations remained in the physiologic range even after a 22 and 36% increase in mg/kg/day Phe tolerance and an achieved Phe intake at 105% and 268% of the dietary reference intake (DRI) for protein. 2 of these responders had classic PKU. 1 patient with mild HPA who started treatment at 2 months of life, had a significant and sustainable reduction in pretreatment blood Phe concentrations, but no increase in the mg/kg/day Phe tolerance. An increase in Phe tolerance could only be demonstrated when expressing the patient's daily Phe tolerance with the DRI for protein showing an increase from 58% at baseline to 78% of normal DRI at the end of the observation. Long-term follow-up of patients with an initial response to treatment with Sapropterin is essential to determine clinically meaningful outcomes. Phenylalanine tolerance should be expressed in mg/kg/day and/or % of normal DRI to differentiate medical therapy related from physiologic growth related increase in daily Phe intake.

RESUMO

BACKGROUND: In previous studies, teriflunomide significantly reduced the annualised relapse rate (ARR) and disability progression. OBJECTIVE: This phase 3, rater-blinded study (NCT00883337) compared teriflunomide with interferon-beta-1a (IFNß-1a). METHODS: Patients with relapsing multiple sclerosis were randomised (1:1:1) to oral teriflunomide 7-or 14 mg, or subcutaneous IFNß-1a 44 µg. The primary composite endpoint was time to failure, defined as first occurrence of confirmed relapse or permanent treatment discontinuation for any cause. Secondary endpoints included ARR, Fatigue Impact Scale (FIS) and Treatment Satisfaction Questionnaire for Medication (TSQM). The study was completed 48 weeks after the last patient was randomised. RESULTS: Some 324 patients were randomised (IFNß-1a: 104; teriflunomide 7 mg: 109; teriflunomide 14 mg: 111). No difference in time to failure was observed. There was no difference in ARR between teriflunomide 14 mg and IFNß-1a, but ARR was significantly higher with teriflunomide 7 mg. FIS scores indicated more frequent fatigue with IFNß-1a, though differences were only significant with teriflunomide 7 mg. TSQM scores were significantly higher with teriflunomide. There were no unexpected safety findings. CONCLUSION: Effects on time to failure were comparable between teriflunomide and IFNß-1a. There was no difference between teriflunomide 14 mg and IFNß-1a on ARR, though ARR was higher with teriflunomide 7 mg. The teriflunomide safety profile was consistent with previous studies.

RESUMO

Pelizaeus-Merzbacher disease (PMD) is a rare leukodystrophy that causes severe dysmyelination in the central nervous system in infancy and early childhood. Many previous studies showed that various proteolipid protein 1 (plp1) mutations, including duplications, point mutations, and deletions, lead to oligodendrocyte dysfunction in patients with PMD. PMD onset and clinical severity range widely, depending on the type of plp1 mutation. Patients with PMD exhibit a delayed mental and physical development phenotype, but specific pharmacological therapy and clinical treatment for PMD are not yet well established. This review describes PMD pathology and establishment of new clinical treatment for PMD. These findings support the development of a new therapy for PMD and these treatments may improve the quality of life in patients with PMD.
