RESUMO

BACKGROUND: Thromboembolic events are a common complicated health problem. Although anticoagulants have several positive effects on these conditions, they also have several characteristics that strongly affect compliance and satisfaction. The purpose of this investigation is to explore the association between treatment satisfaction and self-efficacy in a sample of patients using anticoagulation therapy and determine the influence of sociodemographic and clinical factors on both aspects. METHODS: This was a cross-sectional exploratory study carried out in Palestine. The Arabic version of the Anti-Coagulant Treatment Satisfaction Scale (ACTS) assessed treatment satisfaction. In addition, the Arabic version of the 6-Item Self-Efficacy for Managing Chronic Diseases (SES6C) was used to assess self-efficacy. RESULTS: A total of 300 patients using anticoagulants (average age 51.95 and SD 17.98) were included. There is a modest correlation between treatment satisfaction and self-efficacy (r = 0.345; p <  0.001). The mean and median self-efficacy scores were 38.41 ± 9.88 and 39.00 (interquartile range: 33.00-46.00), respectively. Overall, patients reported a moderate burden and benefit score. The mean and median of the acting burden were 43.30 ± 10.45, and 43.30 (interquartile range: 36.00 to 51.00), respectively. The results showed that young age, higher education, employment, use of fewer medications, and having fewer diseases were significantly associated with higher self-efficacy behaviors. The results also showed that new oral anti-coagulants (NOACs) had a higher degree of self-efficacy and ACTS benefit scores (41.00 (33.75-47.00), p = 0.002; 13.00 (12.00-15.00), p <  0.001, respectively), than vitamin k antagonists (VKA). CONCLUSIONS: The results demonstrated a significant relationship between treatment satisfaction and self-efficacy, and certain sociodemographic and clinical characteristics influence both. We found that there is a higher degree of self-efficacy and treatment satisfaction among patients who use NOACs than those who use UFH / VKA. Therefore, patients should be motivated to increase their knowledge about anticoagulant therapy. Healthcare providers should play an active role in educating patients, increasing their self-esteem, and awareness about anticoagulant drugs. Importantly, this study was an explanatory one, and it includes a low proportion of patients with venous thromboembolism. This encourages future research on a large scale of patients, considering the indications of anticoagulant therapy.

RESUMO

AIMS: Strong evidence indicates that drugs reduce blood lipids and improve cardiovascular end-points, leading to their wide usage. However, the success of these drugs can be affected by poor patient's adherence to prescribed medication. This study aimed to evaluate medication adherence in patients with dyslipidaemia in association with patient beliefs about medicines. METHODS: The study was conducted from January 2019 to July 2019 at the middle governmental primary healthcare clinics in Ramallah and Bethlehem cities, and used a cross-sectional design. Adherence was determined using the 4-item Morisky medication adherence scale, while beliefs were determined using the Beliefs about Medicines Questionnaire. RESULTS: Of 220 patients, 185 agreed to participate in the study, resulting in a response rate of 84.1%. Of the participants, 106 (57.3%) were men, and almost half (88, 46.5%) were ≥56 years. Medication non-adherence was high (47.6%), but a majority (65.5%) reported believing their treatment to be necessary for their continued good health. Accordingly, the mean necessity score (17.3, SD 3.7) significantly outweighed (P < .001) the mean concerns score (14.0, SD 3.5). Multivariate regression demonstrated four variables to be significantly correlated with non-adherence: illiterate (OR = 2.52; CI: 0.9-4.3; P = .03), polypharmacy (OR = 3.18; CI: 1.9-5.7; P = .007), having comorbidity (OR = 3.10; CI: 2.2-4.6; P = .005) and having concerns about side effects (OR = 2.89; CI: 1.1-4.6, P = .04). CONCLUSION: Non-adherence among patients taking lipid-lowering agents was high despite most holding positive beliefs regarding medication necessity. This may be due to concern also being high. Physicians should identify and target high-risk patients and individualise their treatment plans in order to achieve adequate control of dyslipidaemia.

RESUMO

AIMS: Inappropriate use of antibiotics is one of the most important factors contributing to the emergence of drug resistant pathogens. The purpose of this study was to measure the clinical impact of antimicrobial stewardship programme (ASP) interventions on hospitalized patients at the Intensive care unit at Palestinian Medical Complex. METHODS: A prospective audit with intervention and feedback by ASP team within 48-72 h of antibiotic administration began in September 2015. Four months of pre-ASP data were compared with 4 months of post-ASP data. Data collected included clinical and demographic data; use of antimicrobials measured by defined daily doses, duration of therapy, length of stay, readmission and all-cause mortality. RESULTS: Overall, 176 interventions were made the ASP team with an average acceptance rate of 78.4%. The most accepted interventions were dose optimization (87.0%) followed by de-escalation based on culture results with an acceptance rate of 84.4%. ASP interventions significantly reduces antimicrobial use by 24.3% (87.3 defined daily doses/100 beds vs. 66.1 defined daily doses/100 beds P < 0.001). The median (interquartile range) of length of stay was significantly reduced post ASP [11 (3-21) vs. 7 (4-19) days; P < 0.01]. Also, the median (interquartile range) of duration of therapy was significantly reduced post-ASP [8 (5-12) days vs. 5 (3-9); P = 0.01]. There was no significant difference in overall 30-day mortality or readmission between the pre-ASP and post-ASP groups (26.9% vs. 23.9%; P = 0.1) and (26.1% vs. 24.6%; P = 0.54) respectively. CONCLUSIONS: Our prospective audit and feedback programme was associated with positive impact on antimicrobial use, duration of therapy and length of stay.

RESUMO

Irradiation of an acetonitrile solution of 4-aryl-3,5-dibenzoyl-1,4-dihydropyridine derivatives 1a-c and maleimides 2a-c using medium pressure Hg-arc lamp (λ > 290) nm afforded three different cycloadducts 4, 5, 6 in addition to the oxidation products 3. These results indicate that compounds 1a-c undergoes intermolecular cycloaddition reaction through three biradical intermediates and behave photochemically different than those reported previously for the analogous 3,5-diacetyl and 3,5-dicarboxylic acid derivatives. The present work also offers simple access to novel tricyclic and tetracyclic nitrogen heterocyclic ring systems of potential biological and synthetic applications. The structure of the photoproducts was established spectroscopically and by single crystal X-ray crystallography.

RESUMO

The use of single-sideband subcarrier modulation (SCM) with Nyquist (N) pulse shaping for cost-effective spectrally-efficient wavelength division multiplexed transmission with direct detection is described. Transmission of digitally pre-compensated 7 × 11 GHz-spaced QPSK SCM channels at 14 Gb/s per channel is experimentally demonstrated over distances of up to 800 km of uncompensated standard single-mode fiber (SSMF) (13440 ps/nm chromatic dispersion).

RESUMO

BACKGROUND: Complex anatomy of the forearm may impact on local control and survivals of soft tissue sarcoma. Little is known about characteristics and oncologic outcomes following surgical treatment. METHODS: Demographic and tumor data of 117 patients with forearm soft tissue sarcoma were collected and analyzed. Following limb salvage, survivals, and prognostic factors were studied. RESULTS: Seventy-three patients were males (62%) and 53 (45%) were referred after unplanned excision. Pleomorphic undifferentiated sarcoma was most frequent (45%). The average tumor size was 5.1 cm and grade III histology was mostly identified (53%). With radiotherapy, local recurrence occurs in 8 patients (7%) and 30 patients (24%) developed metastasis. Overall survival, disease free survival, local recurrence free survival, and metastasis free survival were 83%, 74%, 93%, and 74%, respectively. Better survival was found for grade I (80% vs. 60%) and small size (<5 cm) (72% vs. 47%). Large size tumor, extra-compartmental site, extramuscular, and virgin tumor were positive predictors of metastasis. CONCLUSION: Soft tissue sarcomas of the forearm are often referred after unplanned excision. Limb salvage was achieved for most and local recurrence remained low in context of radiotherapy. Metastatic progression remained frequent. Low grade and small size were predictors of survival.

RESUMO

In situ and ex situ Raman analyses of porous Ni/CGO electrodes reveal differences in the amount, location and type of carbon formed during CO/CO2 electrolysis. The results demonstrate the limitations of optical in situ techniques applied to Solid Oxide Cells (SOCs) operated in electrolysis conditions. Increased carbon deposition close to the electrode-electrolyte interface is likely to be the result of high charge-transfer current in that area. The positive effect of a CGO interlayer on reducing carbon formation on the fuel electrode is demonstrated.

RESUMO

Irradiation of benzotriazoles 1a-e at λ = 254 nm in acetonitrile solution generated the corresponding 1,3-diradicals which underwent intermolecular cycloaddition with maleimides to afford the corresponding dihydropyrrolo[3,4-b]indoles and with acetylene derivatives to afford indoles as the major products. This offers an interesting and simple access to such ring systems of potential synthetic and biological interest. The structures of the photoproducts were established spectroscopically and by single crystal X-ray crystallography.

RESUMO

Introduction: Moderate-to-high physical activity participation is associated with a reduced risk of infertility. Yet, exercise interventions that target cardiorespiratory fitness, independent of weight loss, are lacking in obesity and female fertility research. Purpose: The primary objective of the PRO-FIT-CARE (PROmoting FITness for CArdiometabolic & REproductive Health) study was to assess the feasibility of a moderate-to-high-intensity online exercise program for persons with obesity and female infertility. Methods: Feasibility, safety, acceptability, and efficacy were assessed by examining: (1) recruitment and consent rate, (2) study retention, (3) adverse events, (4) participant satisfaction, (5) adherence, and (6) cardiorespiratory fitness. Results: Eleven of thirty-two women contacted agreed to participate in the program (34.4% consent rate). Eight participants (72.7%) completed the study. One musculoskeletal injury was reported. There was a 30% adherence rate based on prescribed exercise intensity (60%-80% of heart rate maximum). One of eleven participants attended 80% of the exercise intervention. Based on a weekly satisfaction survey, the program had an overall high level of satisfaction. Compared to sex and age normative data, post-intervention, two of eight participants improved their cardiorespiratory fitness percentile rank. Conclusion: The study highlights challenges with adherence to an online exercise program. While the program was safe and participants reported high levels of program satisfaction, approaches to improve adherence must be incorporated.

RESUMO

AIM: To summarise our centre's experience managing patients with neuroendocrine tumours (NETs) in the first 5 years after the introduction of peptide receptor radionuclide therapy (PRRT) with [177Lu]Lu-DOTA-octreotate (LUTATE). The report emphasises aspects of the patient management related to functional imaging and use of radionuclide therapy. METHODS: We describe the criteria for treatment with LUTATE at our centre, the methodology for patient selection, and the results of an audit of clinical measures, imaging results and patient-reported outcomes. Subjects are treated initially with four cycles of ~ 8 GBq of LUTATE administered as an outpatient every 8 weeks. RESULTS: In the first 5 years offering LUTATE, we treated 143 individuals with a variety of NETs of which approx. 70% were gastroentero-pancreatic in origin (small bowel: 42%, pancreas: 28%). Males and females were equally represented. Mean age at first treatment with LUTATE was 61 ± 13 years with range 28-87 years. The radiation dose to the organs considered most at risk, the kidneys, averaged 10.6 ± 4.0 Gy in total. Median overall survival (OS) from first receiving LUTATE was 72.5 months with a median progression-free survival (PFS) of 32.3 months. No evidence of renal toxicity was seen. The major long-term complication seen was myelodysplastic syndrome (MDS) with a 5% incidence. CONCLUSIONS: LUTATE treatment for NETs is a safe and effective treatment. Our approach relies heavily on functional and morphological imaging informing the multidisciplinary team of NET specialists to guide appropriate therapy, which we suggest has contributed to the favourable outcomes seen.

RESUMO

Temporal lobectomy can be complicated by somatoform disorders, psychiatric illnesses and non-epileptic psychogenic seizures. We report a woman who developed astasia-abasia and psychogenic tremor following temporal lobectomy for refractory epilepsy. To our knowledge, this type of conversion reaction following temporal lobectomy has not been previously reported.

RESUMO

AIMS: To investigate the effect of a range of demographic and psychosocial variables on medication adherence in chronic obstructive pulmonary disease (COPD) patients managed in a secondary care setting. METHODS: A total of 173 patients with a confirmed diagnosis of COPD, recruited from an outpatient clinic in Northern Ireland, participated in the study. Data collection was carried out via face-to-face interviews and through review of patients' medical charts. Social and demographic variables, co-morbidity, self-reported drug adherence (Morisky scale), Hospital Anxiety and Depression (HAD) scale, COPD knowledge, Health Belief Model (HBM) and self-efficacy scales were determined for each patient. RESULTS: Participants were aged 67 ± 9.7 (mean ± SD) years, 56 % female and took a mean (SD) of 8.2 ± 3.4 drugs. Low adherence with medications was present in 29.5 % of the patients. Demographic variables (gender, age, marital status, living arrangements and occupation) were not associated with adherence. A range of clinical and psychosocial variables, on the other hand, were found to be associated with medication adherence, i.e. beliefs regarding medication effectiveness, severity of COPD, smoking status, presence of co-morbid illness, depressed mood, self-efficacy, perceived susceptibility and perceived barriers within the HBM (p < 0.05). Logistic regression analysis showed that perceived ineffectiveness of medication, presence of co-morbid illness, depressed mood and perceived barriers were independently associated with medication non-adherence in the study (P < 0.05). CONCLUSIONS: Adherence in COPD patients is influenced more by patients' perception of their health and medication effectiveness, the presence of depressed mood and co-morbid illness than by demographic factors or disease severity.

RESUMO

A series of new monoazo disperse dyes containing pyrazolopyrimidine moieties was synthesized by coupling malononitrile or 3-aminocrotononitrile with 4-hydroxy- benzenediazonium chloride. Treatment of the resulting products with hydrazine hydrate yields the corresponding 4-arylazoaminopyrazoles, which then react with either 2,4-pentanedione and enaminonitriles or aryl-substituted enaminoketones to give the target pyrazolopyrimidine monoazo disperse dyes. Structural assignments of the dyes were made using both NMR spectroscopic and X-ray crystallographic methods. A high temperature dyeing method, by microwave irradiation, was employed with polyester fabrics. Most of the dyed fabrics tested displayed moderate light fastness and excellent washing and perspiration fastness levels.

RESUMO

An efficient three component reaction with enaminones, primary amines and aldehydes resulted in easy access to 1,4-dihydropyridines with different substituents at the 1-, 3-, 4- and 5-positions. Microwaves improved the reaction yield, reducing also considerably the reaction time and the amount of solvent used. Chiral primary amines gave chiral 1-substituted-1,4-dihydropyridines. The 4-(1-naphthyl) and 4-(phenanthren-9-yl)dihydropyridine derivatives exhibited an interesting photoluminescence behavior, which suggests their potential application as suitable photoinduced intramolecular electron-transfer systems.

RESUMO

BACKGROUND: Myogenic Arthrogryposis Multiplex Congenita type 3 (AMC-3), is a rare congenital condition characterized by severe hypotonia, club feet, and multiple joint contractures often affecting both arms and legs which start prior to birth. CASE PRESENTATION: We report a full-term neonate born to first-degree cousins from fourth-generation consanguineous families, who had with antenatal history of reduced fetal movements. At birth, he was noticed to have bilateral club feet, arthrogryposis, severe hypotonia, and absent deep tendon reflexes. The patient developed difficulty in breathing probably attributed to his generalized severe hypotonia, necessitating mechanical ventilation. His creatinine-phospho-kinase, electromyogram, and brain magnetic resonance imaging were normal. Whole-exome sequencing (WES) was requested for the genetic diagnosis of the case. WES identified a novel homozygous variant c.23415-3799C > G p. in the synaptic nuclear envelope protein1 [SYNE1] gene. Seven out of 20 bioinformatic in silico programs predicted a pathogenic effect for this variant. Segregation analysis of the variant in the parents and siblings revealed that both parents and one sibling were heterozygous for the same mutation which proved the variant significance and its autosomal recessive pattern of inheritance. CONCLUSIONS: AMC3 should be suspected in patients with decreased fetal movements, severe hypotonia, absent deep tendon reflexes, and arthrogryposis. SYNE1 gene mutations can be the underlying genetic defect and molecular genetic testing can prove the diagnosis.

RESUMO

A series of novel monoazo-disperse dyes containing pyrazolo[1,5-a]pyrimidine structures were synthesized starting with the coupling reaction between ethyl cyanoacetate and 4-hydroxybenzenediazonium chloride, followed by treatment of the resulting hydrazone product with hydrazine hydrate. The pyrazolohydrazone 6 is then treated with either 2,4-pentandione and enaminonitrile or aryl-substituted enaminoketones to give the target pyrazolo[1,5-a]pyrimidine dyes 7 and 15a-d. Structural assignments to the dyes were made using NMR spectroscopic methods. A new high temperature method, using microwave heating, was employed to apply these dyes to polyester fibers. Most of the dyed fabrics tested displayed moderate light fastness and excellent washing fastness properties.

RESUMO

Flash vacuum pyrolysis (FVP) of 4-aryl-3-buten-2-ols [ArCH=CH-CH(CH3)OH, where Ar is phenyl, p-MeO, p-Me, p-Cl, p-NO2] gave the corresponding buta-1,3-dien-1-ylbenzene (ArCH=CH-CH=CH2, where Ar is Ph, p-MeO, p-Me, p-Cl, p-NO2) and 7-X-1,2-dihydronaphthalene derivatives (where X is H, MeO); FVP of 1-aryl-3-benzyloxy1-1-butenes and benzyl cinnamyl ethers [ArCH=CHCH(X)OCH2Ph, where Ar is phenyl, p-MeO, p-Me, p-Cl, X is H, Me, Ph] gave the corresponding but-2-en-1-ylbenzene derivatives (ArCH2CH=CH-X, where X is H, Me, Ph) together with benzaldehyde. The proposed mechanism of these pyrolytic transformations was supported by kinetic and product analysis.

RESUMO

OBJECTIVES: This review surveys current pharmacotherapies available for the treatment of diabetic peripheral neuropathy (DPN), emphasising their mechanisms of action. METHODS: A comprehensive literature review focusing on the 'pharmacotherapy and treatment of diabetic peripheral neuropathy' was conducted. The Database of International Pharmaceutical Abstracts, EMBASE, PubMed, OVID, Scopus, Google and Google Scholar were searched, and reference lists of relevant articles were also included. KEY FINDINGS: Diabetic peripheral neuropathy is often inadequately treated, and the role of improving glycaemic control specifically in type-2 diabetes remains unclear. It is crucial to explore the mechanisms of action and effectiveness of available therapies. Major international clinical guidelines for the management of DPN recommend several symptomatic treatments. First-line therapies include tricyclic antidepressants, serotonin-noradrenaline reuptake inhibitors, and anticonvulsants that act on calcium channels. Other therapies include opioids and topical agents such as capsaicin and lidocaine. The objectives of this paper are to review current guidelines for the pharmacological management of DPN and to discuss research relevant to the further development of pharmacological recommendations for the treatment of diabetic neuropathy. SUMMARY: Diabetic neuropathy is a highly prevalent, disabling condition, the management of which is associated with significant costs. Evidence supports the use of specific anticonvulsants and antidepressants for pain management in patients with diabetic peripheral neuropathy. All current guidelines advise a personalised approach with a low-dose start that is tailored to the maximum response having the least side effects or adverse events.

RESUMO

OBJECTIVES: This study had the goal of evaluating the role of treatment satisfaction among diabetic patients in the context of health-related quality of life (QoL) and medication adherence. METHODS: This study, which utilized a cross-sectional design, was conducted at the Primary Healthcare Unit in the Ministry of Health in Ramallah between Feb. and May 2019. Medication adherence was evaluated with the 4-item Morisky Green-Levine (MGL) questionnaire, treatment satisfaction using the Treatment Satisfaction Questionnaire for Medication version 1.4 (TSQM 1.4), and health-related quality of life with the European Quality of Life scale (EQ-5D-3L). RESULTS: Study participants consisted of 380 diabetic patients, of which 220 (57.9%) had high adherence to their medications and 160 (42.1%) had low adherence. Based on the classification of patient responses among the EQ-5D domains, pain/discomfort was the most influenced dimension, with 173 patients (36.1%) reporting problems, (36.1%). Also prominent were anxiety and depression (128 patients, 33.7%) and Mobility (115 patients, 30.3%). A significant relation was observed between QoL and treatment satisfaction (73.8 vs. 69.8; P = 0.016). Treatment satisfaction also had a significant association with the anxiety domain (39.4 vs. 28.7; P = 0.031). CONCLUSION: Participants expressed moderate satisfaction with their treatments; more satisfied patients showed greater medication adherence and had better QoL. Anxiety has been shown to be associated with reduced medication adherence and lower QoL.
