Retrospective review of medicine utilization for noncommunicable diseases in three public sector pharmacies in Jamaica / Revisión retrospectiva del uso de medicamentos para enfermedades no transmisibles en tres farmacias del sector público de Jamaica / Revisão retrospectiva do uso de medicamentos para doenças não transmissíveis em três farmácias da rede pública na Jamaica

ABSTRACT Objective. The rational use of medicines offers a cost-saving strategy to maximize therapeutic outcomes for developing and developed countries. The aim of this study was to evaluate the rational use of medicines for selected noncommunicable diseases (NCDs) at three pharmacies at public hospitals in Jamaica using the World Health Organization's (WHO's) prescribing indicators. Methods. In this retrospective cross-sectional study, prescriptions for adult outpatients containing at least one medicine for cardiovascular disease, diabetes, cancer, chronic obstructive pulmonary disease or asthma that were filled between January and July 2019 were reviewed using WHO's prescribing indicators for the rational use of medicines. Data were analyzed and expressed as descriptive and inferential statistics. For all analyses conducted, significance was determined at P < 0.05. Results. A total of 1 500 prescriptions covering 5 979 medicines were reviewed; prescriptions were mostly written for female patients aged 42-60 years. Polypharmacy was observed in 35.6% (534) of prescriptions, and there was an average of 4 medicines per prescription, with a maximum of 17. Most of the prescriptions at each site were filled, with the main reason for not dispensing a medicine being that it was out of stock. Generic prescribing was high for all sites, accounting for more than 95% (5 722) of prescribed medicines. There was full compliance with prescribing according to the WHO Model List of Essential Medicines at two of the sites, but it was just off the target at Site 1, by 1.4%. Conclusions. The WHO guidelines for the rational use of medicines were followed with respect to the proportion of medicines prescribed from the WHO Model List and the proportion of antibiotics prescribed. The number of medicines per prescription and the proportion of medicines prescribed by generic name did not meet the WHO criteria. However, prescribing was aligned with treatment guidelines for the selected NCDs.

RESUMEN Objetivo. El uso racional de los medicamentos proporciona una estrategia de ahorro de costos para maximizar los resultados terapéuticos tanto en los países en desarrollo como en los países desarrollados. El objetivo de este estudio fue evaluar el uso racional de medicamentos para algunas enfermedades no transmisibles (ENT) seleccionadas en tres farmacias de hospitales públicos de Jamaica, usando los indicadores de prescripción de la Organización Mundial de la Salud (OMS). Métodos. En este estudio transversal retrospectivo se examinaron las prescripciones realizadas a pacientes ambulatorios adultos que incluían al menos un medicamento para enfermedades cardiovasculares, diabetes, cáncer, enfermedad pulmonar obstructiva crónica o asma, dispensadas entre enero y julio del 2019, utilizando los indicadores de prescripción para el uso racional de medicamentos de la OMS. Los datos se analizaron y expresaron mediante estadística descriptiva e inferencial. Para todos los análisis realizados se estableció un nivel de significación de p <0,05. Resultados. Se examinó un total de 1 500 prescripciones que incluían 5 979 medicamentos; la mayor parte de ellas correspondían a pacientes de sexo femenino de 42 a 60 años. Se observó que había polimedicación en el 35,6% (534) de las prescripciones, con un promedio de 4 y un máximo de 17 medicamentos por receta. En todos los centros se dispensó la mayor parte de los medicamentos prescritos, y el motivo principal para no hacerlo fue la falta de existencias del medicamento en cuestión. La prescripción de genéricos fue elevada en todos los centros y supuso más del 95% (5 722) de los medicamentos prescritos. En dos centros la prescripción se realizó en su totalidad de acuerdo con la Lista Modelo de Medicamentos Esenciales de la OMS, pero en el centro 1 no se alcanzó el objetivo por un 1,4%. Conclusiones. Se siguieron las directrices de la OMS para el uso racional de medicamentos en cuanto a la proporción de medicamentos prescritos de la Lista Modelo de la OMS y la proporción de antibióticos prescritos. El número de medicamentos por receta y la proporción de medicamentos prescritos mediante su nombre genérico no cumplieron con los criterios de la OMS. Sin embargo, las prescripciones estaban en consonancia con las directrices de tratamiento de las enfermedades no transmisibles seleccionadas.

Description of the S-Apple mixed rotation and transposition flap: preliminary note / Descrição do retalho misto de rotação e transposição S-Apple: nota prévia

Introduction: The flaps, whose function is to reduce or redirect tension during a closure, are classified based on their primary movement: transposition, advancement, and rotation, each with its characteristics, indications, and peculiarities. Combining the qualities of the transposition flaps with those of rotation, which make up the S-Apple flap, makes it more versatile and with better aesthetic results than the bilobed flap, which denotes the archetype for the appearance of the S-Apple. Method: Having the rotation and transposition flaps as an archetype, four flaps are made in the S-Apple flap, which are rotated and transposed to close the defect. This is excised in a circular format for the oncological safety of margins. The "S" of the flap is traced at a 30º angle in relation to the defect. The arm dimension must be the same diameter as the defect, with the flaps transposed as in a z-plasty, and the flap rotated to cover the defect, resulting from the exeresis of the lesion. Results: No necrosis, infection, dehiscence, recurrences, trapdoor scars, or rotation point elevation were observed. The scars were classified as satisfactory and extremely satisfactory. Conclusion: The S-Apple flap proved versatile and easy to mark with excellent aesthetic and functional results.

O arregimentar das qualidades dos retalhos de transposição com os de rotação, que compõem o retalho S-Apple, tornam-no mais versátil e com melhores resultados estéticos em relação ao retalho bilobado, que denota o arquétipo para o surgimento do S-Apple. Método: Tendo como arquétipo os retalhos de rotação e transposição, no retalho S-Apple são confeccionados quatro retalhos, que são rotacionados e transpostos para fechamento do defeito. Este é excisado em formato circular para segurança oncológica de margens. O "S" do retalho é traçado em um ângulo de 30º em relação ao defeito. A dimensão do braço deve ser do mesmo diâmetro do defeito, sendo os retalhos transpostos como em uma zetaplastia e o retalho rotacionado para cobrir o defeito, resultante da exérese da lesão. Resultados: Não foram observadas necroses, infecção, deiscências, recidivas, cicatrizes em alçapão e elevação em ponto de rotação. As cicatrizes foram classificadas como satisfatórias e extremamente satisfatórias. Conclusão: O retalho S-Apple se mostrou um retalho versátil de fácil marcação com excelentes resultados estéticos e funcionais.

Paying close attention to the therapeutic effect of brolucizumab on polypoidal choroidal vasculopathy and its clinical application / 中华实验眼科杂志

Polypoidal choroidal vasculopathy (PCV) occurs in the middle-aged and elderly population and is characterized by abnormal intrachoroidal vascular patterns such as branching choroidal vascular networks and polypoidal dilatation of vessel terminals, subretinal orange nodular lesions and hemorrhagic or plasma retinal pigment epithelial detachment (PED), which can cause retinal hemorrhage or vitreous hematopoiesis and is one of the major blinding fundus lesions.Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs is currently the main method of PCV treatment, and has certain advantages in eliminating abnormal vascular networks and removing polypoidal lesions, reducing vascular exudation and promoting exudate absorption, and improving visual prognosis.However, frequent intravitreal drug injections increase the risk of infection and the treatment burden for patients.In addition, the high recurrence rate after treatment poses a significant challenge to clinical practice, so the search for new therapeutic agents that are durable and less costly is a focus of clinical research in PCV.The literature from abroad suggests that brolucizumab is a novel small-molecule anti-VEGF humanized monoclonal antibody with the advantages of high tissue penetration, high local drug concentration and bioavailability, small injectable dose, long-lasting efficacy and long injection interval, which brings new hope for the clinical treatment of PCV and improving the prognosis of affected eyes.Although the efficacy and safety of brolucizumab in the treatment of PCV have been well documented, the literature is mainly from Japan, India and Korea, and clinical practice data from China are still lacking.With the approval of the drug in several countries, it is believed that more PCV patients could benefit from this treatment in the near future.Ophthalmologists and researchers in China should closely follow the progress of brolucizumab in the treatment of PCV.

The white blood cell, neutrophil percentage (NEUT%) and D-Dimer at admission, day 1 and day 3 after operation were analyzed and compared retrospectively. The time of abdominal pain at admission, YOO classification, angle from superior mesenteric artery to abdominal aorta(ASA), conservative treatment time, operation time, type and length of stent, vascular remodeling rate and long-term patency rate of stent were analyzed. The measurement data conforming to normal distribution was expressed as mean ± standard deviation ( ± s), t-test was used for comparison between the two groups. Measurement data of skewed distribution were expressed as M ( Q1, Q3), and non-parametric test was used for comparison between groups. Count data were expressed as rate or component ratio(%). The same variable was compared at different time points by repeated measurement data analysis of variance. Results:There were significant differences in white blood cell, NEUT% and D-Dimer between admission and postoperative day 3 in 15 patients. The time to admission for abdominal pain was 24.0(15.0, 78.0) hours. IVS type accounted for 46.7% of YOO type, and the ASA beyond 60° accounted for 66.7%. The conservative treatment time was (34.0±8.6) hours, moreover, the operation time was(153.0±37.8) min. Besides, self-expanding bare stent accounted for 85% of the stent types, moreover, the length of the stents beyond 60 cm was 50%. All patients were followed up for more than 24 months, and the vascular remodeling rate was(89.7±9.7)%.Conclusion:Endovascular self-expanding thin-wall stent placement has better vascular remodeling rate and patency rate for patients with IVS type.

Research progress in surgical diagnosis and treatment of gallstones and acute calculous cholecystitis in the elderly / 国际外科学杂志

Gallstones and acute calculous cholecystitis are common diseases in surgery. China has entered an aging society. Elderly patients are a high incidence group of gallstones and acute calculous cholecystitis. Their surgical diagnosis and treatment strategies need to be formulated individually, and reasonable diagnosis and treatment methods should be comprehensively selected according to the patient′s condition and the medical level of the medical institution. For those who are in good physical condition and can tolerate the operation, it is recommended to give priority to surgical treatment, and the minimally invasive surgery mainly suitable for laparoscopic cholecystectomy (LC) is preferred. Open surgery is more appropriate for complicated conditions or patients whose general conditions are not suitable for laparoscopic surgery. Other minimally invasive treatment measures can be applied at the same time. For patients who can not tolerate surgical treatment, puncture, endoscopy, intervention and other means can be selected, combined with drugs for conservative treatment, so as to obtain the opportunity of surgical treatment or improve the prognosis. In this paper, the latest research literature at home and abroad has been collected to review and summarize the latest research progress in the physiology and aging characteristics of the biliary tract in the elderly, the diagnosis and treatment of gallstones and acute calculous cholecystitis. It is hoped that this paper can provide reference for the clinical diagnosis and treatment of such diseases, and think and prospect the future research.

The important role of tumor microenvironment in the immunotherapy of malignant tumors is gradually recognized. In this paper, the characteristics of immune microenvironment in intrahepatic cholangiocarcinoma has been summarized, and the application of immunotherapy in intrahepatic cholangiocarcinoma has been reviewed, with emphasis on the development of immune checkpoint inhibitors, cancer vaccines and adoptive cellular immunotherapy.

Advances in diagnosis and treatment of hilar cholangiocarcinoma / 国际外科学杂志

Hilar cholangiocarcinoma is the most common extrahepatic malignant tumor in clinic, accounting for about 50%-60% of bile duct tumors. Currently, radical surgical resection is regarded as the best treatment for early hepatic hilar cholangiocarcinoma, but, it’s early lesions have no obvious clinical symptoms. Most patients are already in the advanced stage of the disease when they are admitted to hospital. The surgical resection rate is low, and the 5-year survival rate does not exceed 25%. Locally advanced hepatic hilar cholangiocarcinoma are treated with neoadjuvant chemoradiation therapy followed by surgery, it can prolong survival time of the patient. At the same time, the recurrence rate after surgery can reach 50%-70%, and the cancer easily invades microvessels, lymphatic vessels, peripheral nerves and liver, which is one of the most challenging problems in the field of biliary surgery. Therefore, early diagnosis, perioperative management, adequate and accurate preoperative staging assessment, intraoperative standardized resection, postoperative adjuvant therapy of hilar cholangiocarcinoma, it is of great significance to improve the rate of radical surgical resection and prolong the survival time of patients.

Diagnosis and treatment of hilar cholangiocarcinoma / 国际外科学杂志

Hilar cholangiocarcinoma(HCCA) is a hotpot and a difficult point in the field of hepatobiliary surgery. HCCA is the most common type of cholangiocarcinoma and is characterized by atypical early clinical manifestations, rapid progression and poor prognosis. There is no specific marker for HCCA and its preoperative diagnosis and evaluation mainly relies on imaging examination. Surgical treatment is still the main treatment, but most patients have lost the opportunity of surgical resection by the time of treatment. In recent years, a large number of studies have been conducted on the diagnosis and treatment of HCCA at home and abroad, and the efficacy of HCCA has been improved. Perioperative management, including the selection of preoperative drainage and perioperative chemoradiotherapy and others, improved postoperative survival. Among them, the application of preoperative radiotherapy and chemotherapy in the field of liver transplantation has achieved quite good results. Targeted therapy and immunotherapy have provided new treatment methods for HCCA. This paper reviews the diagnosis and multimodal treatment of HCCA.

Progress in the diagnosis and treatment of Caroli disease / 国际外科学杂志

Caroli disease is a relatively rare genetic disease, also known as congenital intrahepatic cystic cholangiectasis, which is mainly manifested as non-obstructive segmental dilation of large, intrahepatic bile ducts, which is manifested as cysts in imaging and histopathological examination. The pathogenesis of Caroli disease is still unclear, and it is mainly believed to be related to PKHD1 gene mutation. Mutations in this gene often lead to autosomal recessive polycystic kidney disease (ARPKD), so Caroli disease is commonly associated with polycystic kidney disease. Caroli disease usually develops during adolescence and is characterized by recurrent cholangitis, which is diagnosed mainly by imaging. This article reviews the progress of diagnosis and treatment of Caroli disease by reading related literature.
