Introduction: Tuberculosis is closely linked to poverty, with patients facing significant indirect treatment costs. Treating drug-resistant tuberculosis further increases these expenses. Notably, there is a lack of published data on the indirect costs incurred by patients with drug-resistant tuberculosis in Mozambique. Objective: To assess the indirect costs, income reduction, and work productivity incurred by patients undergoing diagnosis and treatment for Drug-Resistant Tuberculosis (DRTB) in Mozambique during their TB treatment. Methods: As part of a comprehensive mixed-methods study conducted from January 2021 to April 2023, this research utilized a descriptive cross-sectional approach, incorporating both quantitative and qualitative methods. The primary goal was to evaluate the costs incurred by the national health system due to drug-resistant TB. Additionally, to explore the indirect costs experienced by patients and their families during treatment, semi-structured interviews were conducted with 27 individuals who had been undergoing treatment for over six months. Results: All survey participants unanimously reported a significant decline in labour productivity, with 70.3% experiencing a reduction in their monthly income. Before falling ill, the majority of respondents (33.3%) earned up to $76.92 monthly, representing the minimum earnings range, while 29.2% had a monthly income above $230.77, the maximum earnings range. Among those who experienced income loss, the majority (22.2%) reported a decrease of up to $76.92 per month, and 18.5% cited a loss exceeding $230.77 per month. Notably, patients with Drug-Resistant Tuberculosis (DRTB) have not incurred the direct costs of the disease, as these are covered by the government. Conclusion: The financial burden of treating Drug-Resistant Tuberculosis (DRTB), along with the income reduction it causes, is substantial. Implementing a patient-centred, multidisciplinary, and multisector approach, coupled with strong psy

An Analysis of the Accounting Costs Associated with 20-Month DR TB Regimens in Maputo City, Mozambique

Introduction: Socioeconomic and demographic conditions in a country can influence tuberculosis incidence and mortality, with nearly 95% of tuberculosis-related deaths occurring in poorer countries. Mozambique is among the 30 countries with the highest TB burden. Objective: The study aimed to estimate the average direct medical cost of treating drug-resistant tuberculosis in 19 health centers in Maputo City, Mozambique. Methods: A retrospective analysis of direct medical costs was conducted on patients aged 18 and older who completed 20-month drug-resistant tuberculosis treatment regimens in Maputo City in 2019. Results: This analysis covered 140 patients who completed a 20-month treatment regimen, with 64.3% (78) being male and 35.7% (62) female. Approximately 50% of the participants were aged between 29 and 47. The average direct medical cost of DRTB treatment was $4789.43, reaching up to $6568.00, with a standard deviation of $753.26, including clinical interventions and treatment. Conclusion: The direct medical costs for a basic treatment package for a patient with drug-resistant TB in Mozambique equal 36 minimum wages. Developing alternative and innovative funding mechanisms and identifying ways to mitigate costs through the use of generic medicines would be beneficial.

In forest modeling to estimate the volume of wood,artificial intelligence has been shown to be quite effi-cient,especially using artificial neural networks(ANNs).Here we tested whether diameter at breast height(DBH)and the total plant height(Ht)of eucalyptus can be pre-dicted at the stand level using spectral bands measured by an unmanned aerial vehicle(UAV)multispectral sensor and vegetation *** do so,using the data obtained by the UAV as input variables,we tested different configurations(number of hidden layers and number of neurons in each layer)of ANNs for predicting DBH and Ht at stand level for different Eucalyptus *** experimental design was randomized blocks with four replicates,with 20 trees in each experimental *** treatments comprised five Eucalyptus species(***,***,***,***-dis,and ***)and Corymbria *** and Ht for each plot at the stand level were measured seven times in separate overflights by the UAV,so that the multispectral sensor could obtain spectral bands to calculate vegetation indices(VIs).ANNs were then constructed using spectral bands and VIs as input layers,in addition to the categorical variable (species), to predict DBH and Ht at the stand level simultaneously. This report represents one of the first appli-cations of high-throughput phenotyping for plant size traits in Eucalyptus species. In general, ANNs containing three hidden layers gave better statistical performance (higher esti-mated r, lower estimated root mean squared error-RMSE) due to their greater capacity for self-learning. Among these ANNs, the best contained eight neurons in the first layer, seven in the second, and five in the third (8 − 7 − 5). The results reported here reveal the potential of using the gener-ated models to perform accurate forest inventories based on spectral bands and VIs obtained with a UAV multispectral sensor and ANNs, reducing labor and time.

A Review on Renewable Energy Systems for Irrigation in Arid and Semi-Arid Regions

Journal of Power and Energy Engineering 2019年第10期7卷 21-58页

The lack of water in arid and semi-arid regions has often limited agricultural production. Indeed, even where water is available for irrigation, the lack of electricity, as well as the high costs of diesel, has created constraints on small farmers. The purpose of this research is to review the renewable energy potential available in arid and semi-arid zones that can be used for irrigation as a substitute for fossil fuels. In this review, the solar thermal irrigation, solar photovoltaic (PV) irrigation, wind pumping and biomass pumping are discussed. The comparison of different hybrid pumping systems and analyses of renewable sources irrigation assessment in arid and semi-arid regions of Mozambique also are discussed. The results of this study showed that there are still certain technological limitations regarding the use of solar thermal energy for irrigation. As far as wind power is concerned, the analysis of the pumping water life cycle cost showed that the wind power water pumping system is more economical and viable compared to the diesel based system. However, the study concluded that photovoltaic solar energy has been shown to be more viable for pumping water for irrigation in arid and semi-arid regions.

BACKGROUND:Obstructive jaundice is a common condition in advanced digestive *** procedures can improve quality of life and allow patients to attempt a systemic *** anastomosis is still the procedure of choice for patients in many *** a surgical bypass is not possible,biliary drainage can be done by placing endoscopic or transparietal stents,which are less durable methods even when an expandable stent is employed. METHODS:A 47-year-old male with an excellent clinical status and a previous cholecystectomy and an exploratory laparotomy for advanced gastric cancer was referred with obstructive jaundice.A preoperative CT scan showed a dilated bile duct and a small mass at the distal hepatic *** other signs of metastasis were found.A surgical bilioenteric anastomosis was *** surgery,a distal choledochal obstruction and a mesenteric retraction by a lymph node mass prevented the jejunum to ascend for a bilioenteric anastomosis. Surgically,an alternative bilioenteric bypass was performed by means of an ileal loop interposition between the bile duct and the jejunum. RESULT:The recovery of the patient was uneventful and his bilirubin levels normalized after one *** patient was then referred for systemic chemotherapy. CONCLUSIONS:This alternative biliary bypass can be safely and easily performed,and may be a good alternative for patients already referred for surgery because of a better life expectancy and when the jejunum is not an alternative.
