Developed in this work are the principles for creation of a system to control and governing the energy efficiency of solar panels providing power supply for LED luminaires. Realization of these principles allows the most efficient using the electric power generated by solar panels, to save in a real-time scale the data about system functions as well as provide a complex analysis of these data. Optimization of using the electric energy generated by solar panels will enable to determine the maximum possible power in each specific moment and to automatically tune its consumption. The complex data obtained with this system can be further used for not only statistical fixation of the produced and consumed electric energy in fact but also for prediction of the energy amount that will be generated by these solar panels in future. The analysis of results will enable to optimize the area of solar panels and more exactly determine parameters of electronic components both for illumination systems and designing solar photoelectric stations of various purposes.

In this paper, we study a field plate high electron mobility transistor (FP-HEMT) device with Al2O3 passivation, InAlN/GaN lattice matched, and a gate of 30-nm length. We simulate its performances evaluation in function of the thermal effect mode. We also show the analysis and simulation of this device with the proposed equivalent circuit that consists of inter-electrode distributed extrinsic parasitic and additional intrinsic feedback. Then, a study on how it can be used in thermal environment for satellite application. The simulator Tcad-Silvaco software has been used to predict results of the characteristics specified with a genetic algorithm, to improve the computation time and model accuracy. The obtained results confirm the feasibility of using this new device model with InAlN thin barrier, Filip Chip and field plate at the same time and in one structure at high amplifier signal mode, as well as in a geostationary thermal orbital.

The issues discussed in this paper provide for further development of studies in the sphere of imaging spectroscopy and laser vision. In terms of forming the information fields (radiation fields), the electro-optical systems are subdivided into the passive and active ones. Passive electro-optical systems use the information fields formed by natural radiation sources, whereas the active ones suggest using artificial sources. Comparative analysis of mathematical and physical issues of designing the electro-optical systems with dynamic spectral processing of optical radiation of the passive and active types has been performed. It has been shown that the controlled dynamic spectral processing of optical radiation can be implemented within the passive and active electro-optical systems on the basis of the same algorithm that represents operation of the optical processor performing the mathematical operation of dot product. The authors have developed the block diagram of an active electro-optical system with dynamic spectral processing. The algorithm for optimal detection of optical signals has been developed using basics of the signal detection theory. Mathematical modeling of target detection against an inhomogeneous background has been performed. It has been shown that the optimal dynamic spectral processing of optical radiation in active electro-optical system enables to separate the desired optical signal by suppressing the background signal.

BACKGROUND AND OBJECTIVES

Blunt use is a popular mode of marijuana consumption among adolescents in the United States, but little is known about how its prevalence has changed over time or factors associated with its use. With this study, we assessed trends and correlates of past (ever used but not in the past 30 days) and current (used in past 30 days) blunt use among adolescents in Florida.

METHODS

We analyzed data from 2010–2020 cross-sectional, statewide representative Florida Youth Tobacco Surveys that comprised 461 706 middle and high schoolers using Joinpoint to calculate annual percentage change (APC) in the weighted prevalence of past and current blunt use. A weighted multivariable regression model was developed by using 2019–2020 Florida Youth Tobacco Survey data to examine the factors associated with past and current blunt use.

RESULTS

Whereas the prevalence of past (APC = −5.32%) and current (APC = −5.28%) blunt use significantly decreased from 2010 to 2015, an increasing trend in current use prevalence (APC = 14.91%) was observed from 2015 to 2018 and has been approximately constant ever since. Similar increasing trends were observed in current blunt use among female students (APC = 14.92%), middle schoolers (19.57%), and non-Hispanic (NH) white students (APC = 11.12%) from 2016 to 2020. Several factors were consistently associated with greater odds of both past and current blunt use for both middle and high schoolers, including older age, being NH Black (versus NH white), past and current use of cigarettes, electronic cigarettes, hookah, cigars, and ever vaping marijuana.

CONCLUSIONS

Although blunt use among Florida youth decreased from 2010 to 2015, substantial increases were observed since 2015, suggesting that existing tobacco control programs should incorporate marijuana (and blunt) modules into existing tobacco and nicotine prevention programs.
Carga puntiforme, equações de Maxwell e o significado da corrente de deslocamento
Authors: Facin Paulo Cesar
Published: June 2021

Consideramos o caso de uma carga puntiforme se deslocando em relação ao referencial do laboratório com velocidade constante, assumimos os campos elétrico e magnético dados pela transformação de Lorentz do quadri-potencial eletromagnético. Assumindo um limite que tende a zero para o volume da carga mostramos que, como era esperado, essa escolha para os campos respeita perfeitamente as quatro equações de Maxwell, além disso, para nossa surpresa, o termo da corrente de deslocamento generaliza o termo de densidade de corrente e torna a lei de Ampere-Maxwell mais simétrica em relação a lei de Faraday. Percebemos então que a natureza discreta desse problema possibilitou capturar a variação do campo elétrico com o tempo que é fundamental para o entendimento da corrente de deslocamento e a lei de Ampère-Maxwell.

Prevalence, determination, and control of histamine formation in food concerning food safety aspect
Authors: Hoang Chuyen , Nguyen Thi-Van , Le Thanh Do
Published: June 2021

Histamine is a toxic metabolite produced in foods containing a high level of free histidine. This compound can be present in various food sources, especially seafood, dairy products, and fermented foods. Histamine poisoning is one of the most common health risks caused by consuming spoiled foods or improper processed and stored foods. This food poisoning usually causes mild symptoms with higher recovery rates, so people underestimate this hazard. Thus, understanding histamine formation food sources with a high risk for this poisonous agent is critical in improving the awareness of this hazard for food producers and consumers. To avoid histamine-associated food poisoning, the development of control solutions to minimize the formation of histamine and the sufficient detection methods to examine the content of this metabolite in food products are vital. In addition to quality control application and hazards management programs in food processing, the appropriate food regulations identifying the precise limit of histamine in foods are essential for preventing this poisoning from occurring in the food supply chain. This review discusses the prevalence, control strategies, detection techniques, and regulations related to histamine hazards in foods.

Published: June 2021

The aim of the study was to investigate the effectiveness of different schemes of basic asthma therapy depending on the polymorphism of the LTC4 gene.

Materials and methods. 181 patients with asthma were recruited to participate in the study. All patients included in the study underwent a general clinical study, spirometry, the level of asthma control was determined by Asthma control questionnaire 5 (ACQ-5), by studying the polymorphism of the LTC4 gene, it was determined that patients belong to the A/A, A/C and C/C genotypes.

Results. Allelic -444C polymorphism of the LTC4-S gene (rs 730012) had the following genotype frequency among asthma patients: A/A – 77 people (42.6 %), A/C – 73 people (40.3 %) and C/C – 31 people (17.1 %).

In groups of patients with genotypes A/A and A/C, during treatment with a low dose of ICS and montelukast, there was a significant improvement in FEV1 and the score according to the ACQ-5 questionnaire (asthma control level). However, in the group of patients with the C/C genotype, there were no significant changes in FEV1 and the score according to the ACQ-5 questionnaire.

In the groups of patients with genotypes A/A and C/C on the background of increasing the dose of ICS to medium in a fixed combination with LABA compared with the results of treatment with low-dose ICS and montelukast, there was a significant improvement in FEV1 and asthma control – ACQ- 5. At the same time, in the group of patients with genotype A/C, there were no reliable indicators of FEV1 and ACQ-5 score changes.

Conclusions. The frequency of genotypes A/A, A/C and C/C for LTC4S polymorphism in the studied population are 42.6 %, 40.3 % and 17.1 %, respectively.

Patients with genotypes A/A and C/C have a significant response to treatment with a low dose of ICS and montelukast in the form of an improvement in FEV1 and ACQ-5 score.

Increasing the dose of ICS up to moderate in a fixed combination with β2-LABA in groups of patients with genotypes A/A and C/C leads to a significant improvement in the FEV1, as well as in the asthma control level - ACQ-5
Morphological manifestations of experimental paclitaxel-induced sciatic neuropathy under correction of 2-ethyl-6-methyl-3-hydroxypyridine succinate
Authors: Ostrovskyi Mykola
Published: June 2021

Paclitaxel is an effective chemotherapeutic agent for many cancers, but it has a number of limiting side effects that not only significantly reduce the quality of life of patients, but also limit their further treatment. Peripheral neuropathy is one of these, but there are currently no proven effective druHS for the prevention or treatment of paclitaxel-induced neuropathic pain (PINP) in particular, or chemotherapy-induced peripheral neuropathy (CIPN) in general. 2-ethyl-6-methyl-3-hydroxypyridine succinate (HS) is a derivative of succinic acid with neuroprotective, antihypoxic, membrane-protective, nootropic, sedative effects.

The aim of the study was to study the effect of the neuroprotective agent HS on the pathomorphogenesis of the sciatic nerves under conditions of paclitaxel-induced peripheral neuropathy in the experiment.

Materials and methods. The experiment was carried out on 80 white rats, which were injected intraperitoneally with paclitaxel (Actavis, Romania), previously dissolved in isotonic saline at a dose of 2 mg / kg of body weight four times every other day until a total dose of 8 mg / kg was reached. Then forty of these animals were injected intraperitoneally with 2-ethyl-6-methyl-3-hydroxypyridine succinate at a dose of 10 mg / kg (the remaining 40 rats received intraperitoneal water for injection). Morphological studies were carried out on the first, seventh, fifteenth, twenty-eighth, sixtieth, ninetieth and one hundred and twentieth days after the last injection of the drug. We investigated the pharmacological potential of HS in the prevention and treatment of CIPN at the level of sciatic nerve (SN) morphology.

Results. The maximum value of the average profile area of myelinated nerve fibers with the use of HS is significantly lower than with uncorrected flow, and is (78.12±2.24) μm2 compared to (94.04±1.03) μm2 (p <0.001). The introduction of HS provides a stable content of the value of the ratio of the areas of the axial cylinder and the fiber within 0.39±0.01 (first day) - 0.44±0.01 (ninetieth day), and a rapid recovery of the indicator value to normal values during the final 30 days of the experiment. the maximum value of the index of the profile area of the myelin sheath with the introduction of HS is 1.4 times less than with an uncorrected flow, and is, respectively, (49.01±1.59) μm2 and (69.77±1.87) μm2 (p <0.001). HS provides a more intensive restoration of the indicator of the area of the myelin sheath during the 90th - 120th day of the experiment.

Conclusions. Our results allow us to conclude that the introduction of HS creates a protective effect against paclitaxel-induced peripheral neuropathy (PIPN) by acting on both the axial cylinder and the myelin sheath of the heart failure. Due to the known pathophysiological mechanisms of the development of neuropathy, this method can be a promising therapeutic agent for the prevention and treatment of PIPN

Background. Monitoring of documented vaccination is one of the indicators of the epidemiological supervision quality of preventive vaccination. It is crucial for epidemical situation prevention. Objective. The aim of the study is to estimate immunization and immunization coverage levels according to National Immunization Schedule (NIS) for children population in Russia. Methods. Immunization rates were estimated according to preventive vaccination cards (form №063/y) and children development cards (form №112/y) among children aged from 6 months to 15 years in 8 towns of Russia. Immunization was determined by the ratio of people who has fully performed all the vaccines from NIS (version of the year 2014), while immunization coverage – by the ratio people who has received at least one dose of corresponding vaccine. Results. The study has included data from 2,687 vaccinated children. The highest levels of immunization and immunization coverage were against tuberculosis (98.1% each), hepatitis B (85.9% and 96.5%), measles, mumps and rubella (84.4% and 93.9%). Immunization against diphtheria, pertussis and tetanus significantly differed from their immunization coverage (60.5% and 94.9%), as well as for poliomyelitis (65.0% and 94.9%). Relatively low immunization and immunization coverage levels were observed for pneumococcal infection (27.6% and 47.1%) and influenza (5.8% and 30.5%). The increase in the immunization level with age was observed for all vaccines, except pneumococcal vaccine. Conclusion. Immunization and immunization coverage against infections included in NIS vary significantly. The highest immunization and immunization coverage levels for all age groups were revealed for tuberculosis vaccine, and the lowest — for influenza vaccine.

This study was carried out at two farms: Carcará Farm, certified by Associação de Certificação Instituto Biodinâmico, and at Estufa Limoeiro Farm, of conventional cultivation. They were located in Guaraciaba do Norte, Ceará, at the geographic coordinates 04°10’52” South, 40°49’41” West, and elevation of 885 m. The main objective of this research was to compare, based on economic, social and environmental indicators, two irrigated production systems, one organic one and a conventional. Data were collected through interviews with the farmers. Generation of jobs, added value, and the farmer’s income were analyzed as variables associated with the socioeconomic dimensions. For the environmental analysis, the biological activity of the soil was evaluated using the variables organic carbon (OC), microbial biomass carbon (MBC), soil basal respiration (SBR), microbial quotient (qMIC) and metabolic quotient (qCO2). The organic cultivation system provided a generation of direct jobs per unit area three times higher than average of irrigated agriculture in the Brazilian semi-arid region, characterizing it as a system of greater social contribution. When compared to the conventional system, the organic farming system showed a lower risk associated with the economic dimension. The production unit with organic cultivation had higher environmental sustainability since the soil is in more satisfactory physical and chemical conditions for the development of microorganisms.

ABSTRACT Objective: to evaluate symmetry after breast-conserving surgery (BCS) for cancer. Methods: a prospective study of patients undergoing BCS. These patients were photographed using the same criteria of evaluation. The references points used were the nipple height difference (NH), the nipple-manubrium distances (NM), nipple-sternum distances (NS) and the angle between the intramammary fold and the nipple (nipple angle; NA). ImageJ software was used. Three breast symmetry models were evaluated: excellent/others (model 1), excellent-good/others (model 2) and others/poor (model 3). The ROC curve was used to select acceptable criteria for the evaluation of symmetry. Decision tree model analysis was performed. Results: a total of 274 women were evaluated. The BCCT.core result was excellent in 5.8% (16), good in 24.1% (66), fair in 46.4% (127) and poor in 23.7% (65). The difference in NH was associated with good breast area (0.837-0.846); acceptable differences were below 3.1 cm, while unacceptable values were greater than 6.4 cm. Differences in the NM were associated with average breast area (0.709-0.789); a difference in value of less than 4.5 cm was acceptable, while values greater than 6.3 cm were unacceptable. In the decision tree combined model, a good-excellent outcome for patients with differential (d) dNH = 1 (0 to 5.30 cm) and dNM ≠ 3 (<6.28 cm); and for a poor/poor result, values dNM = 3 (> 6.35). Conclusions: the results presented here are simple tools that can assist the surgeon for breast symmetry evaluation.

The total number of cases in which the training surgeons participated as first assistant was 418, with an average of 20.9 per surgeon. The time of pre-clinical training had an average of 116 days (48-205). Conclusion: the new model proposed had good acceptance by all surgeons trained and proved safe in the initial sample.
Lumbar and para-iliac hernias: an alternative technique
Authors: SIMÕES MARIA PESSOLE BIONDO , MANSUR ALEXANDRE CONTIN , PIMENTEL SILVANIA KLUG
Published: June 2021

ABSTRACT Lumbar and para-iliac hernias are rare and occur after removal of an iliac bone graft, nephrectomies, retroperitoneal aortic surgery, or after blunt trauma to the abdomen. The incidence of hernia after the removal of these grafts ranges from 0.5 to 10%. These hernias are a problem that surgeons will face, since bone grafts from the iliac crest are being used more routinely. The goal of this article was to report the technique to correct these complex hernias, using the technique of fixing the propylene mesh to the iliac bone and the result of this approach. In the period of 5 years, 165 patients were treated at the complex hernia service, 10 (6%) with hernia in the supra-iliac and lumbar region, managed with the technique of fixing the mesh to the iliac bone with correction of the failure. During the mean follow-up of 33 months (minimum of 2 and maximum of 48 months), there was no recurrence of the hernias.

Published: June 2021

ABSTRACT: This study determined the meteorological variable that most contribute to the productivity of sugarcane stalks in the northwest and central regions of Rio Grande do Sul. The following sugarcane genotypes were used: UFSM XIKA FW, UFSM LUCI FW, UFSM PRETA FW, UFSM DINA FW, UFSM MARI FW, and IAC87-3396. The UFSM cultivars originate from a mutation process in the breeding program conducted at the Federal University of Santa Maria, Frederico Westphalen campus, and have low temperature tolerance. The productivity-associated morphological characters included in the models were average stem diameter, average stem number per meter of furrow, and average stem height. The following meteorological variables were used: minimum air temperature, precipitation, incident solar radiation, and accumulated thermal sum. Pearson’s correlation, canonical correlations, and Stepwise regression were performed between morphological characters and meteorological variables: minimum air temperature had the greatest influence on sugarcane productivity in the studied regions, and accumulated thermal sum showed the highest correlation and contributed most to stem diameter and average stem height. Thus, the models indicated that the growth of sugarcane is positively associated with the accumulated thermal sum, and sugarcane can be cultivated at the studied regions.

Published: June 2021

ABSTRACT: Meloidogyne enterolobii is known as the most aggressive root-knot nematode (RKN) in Brazil. Common bean (Phaseolus vulgaris) cultivated in the experimental field in Morrinhos, Southern Goiás State, exhibited symptoms typical to those caused by RKN. In order to clarify the etiology of the disease, root systems were analyzed. Typical galls of varying thickness were observed, with thickening larger than 3 cm in diameter containing RKN females inside roots and egg masses on the root surface. The identification of the nematode species was confirmed by isoenzyme electrophoresis (esterase and malate dehydrogenase phenotypes). This is the first report of M. enterolobii in Goiás and in Brazil parasitizing common bean under field conditions. This result is an alert to producers and to the State phytosanitary defense authorities, in order to prevent the further dissemination of this pest, especially in fields of common bean and industrial tomato in the State.

ABSTRACT: This study aimed to evaluate the effects of Reiki therapy on postoperative pain in bitches undergoing elective minimally invasive ovariohysterectomy (OVH). Thirty bitches were randomly assigned to three groups: Control, Placebo, or Reiki. All dogs received methadone as preanesthetic medication (PAM), meloxicam in the preoperative period, propofol for anesthetic induction, and isoflurane for anesthetic maintenance. Immediately after OVH, the dogs in the Reiki were submitted to a single session of Reiki therapy, dogs in the Placebo received simulated Reiki therapy from a non-therapist, and dogs in the Control received no treatment. All dogs were evaluated for pain using short-form Glasgow composite measure pain scale (CMPS-SF) and visual analog scale (VAS) before (M0) and 2 (M2), 4 (M4), 8 (M8), 12 (M12), and 24 hours (M24) after administration of PAM. Comparing the CMPS-SF scores between the groups, at M2 Reiki scores were lower than those of the Placebo and at M4 those in the Reiki were lower than those of the Control or Placebo groups. Comparing the VAS scores, at M4 and M8, Reiki scores were lower than those of the Control or Placebo groups. Additional analgesia (morphine 0.2 mg.kg-1 intramuscularly) was administered to three bitches in Control and to four bitches of the Placebo. Reiki did not require additional opioid analgesia in the postoperative period. It was concluded that Reiki therapy provided analgesic effect and contributed to improve postoperative comfort of bitches submitted to elective OVH.

ABSTRACT: The P-glycoprotein (P-gp) is a transmembrane protein encoded by the MDR1 gene that functions as a biological barrier by extruding toxins and xenobiotics out of cells. The MDR1 gene can carry a mutation called nt230(del4), which is a deletion of four base pairs resulting in the formation of a non-functional protein that may predispose to severe toxicosis, as observed in dogs with sensitivity to ivermectin. Several breeds have been described as carriers of the mutation, including German Shepherds (GS). However, the presence of the mutant allele in this breed has not been described in Brazil. This study aimed to determine the genotypic and allelic frequency of the nt230(del4) mutation in the MDR1 gene in GS from Southern Brazil. Blood samples were collected from 79 GS in the state of Rio Grande do Sul and genotype for the MDR1 gene was performed. Seventy-eight (98.7%) dogs were dominant homozygous genotype (wild) and one (1.3%) was heterozygous. This study showed that there is a low frequency (0.6%) of the mutant allele while the frequency of the wild allele is high (99.4%) in this specific population. This is the first report of the presence of the nt230(del4) mutation in the MDR1 gene in GS in Brazil. This information is important for breeders to prevent dissemination of the mutant allele in the national breeding population and international exchange of animals for breeding; for owners and veterinarians to be aware when dispensing and administering medications for GS dogs in Brazil.

Published: June 2021

ABSTRACT: Left ventricular false tendons are fibrous or fibromuscular bands that transverse the ventricular cavity and have no attachment to the mitral valve in many species. In cats it is considered a congenital defect that is rarely related to clinical disease and death in adult cats. A 45 days-old mixed breed cat had a history of inappetence since birth. At the physical exam the patient was lethargic and presented restrictive dyspnoea. At necropsy, there were marked ascites, hydrothorax, hepatomegaly with enhanced lobular pattern (nutmeg liver), and the lungs were markedly diminished (compressive pulmonary atelectasis). The heart was enlarged due to marked dilation of the cardiac chambers. Moreover, multiple slightly whitish and irregular cord-like structures were connecting the posterior papillary muscle to the interventricular septum (excessive moderator bands /left ventricular false tendons) at the left ventricle. Microscopically, these structures were characterized by a marked proliferation of fibrous connective tissue intermixed with Purkinje cells and well-differentiated cardiomyocytes lined by a single layer of endocardium. This study described a case of excessive moderator bands (left ventricular false tendons) in a young cat associated with congestive heart failure and death.

ABSTRACT: Onion is an important vegetable crop, predominantly grown under conventional tillage system management. Alternatively, the vegetable no-tillage system uses cover crops to form a residue layer, which improves soil physical, chemical, and biological attributes. Aiming to understand the interaction of mycorrhizal and non-mycorrhizal cover crops, phosphatase activity, and soil phosphorus availability and uptake by plants, a no-tillage vegetable production system experiment with onion was carried out in Ituporanga, Southern Brazil. The treatments were black oats (Avena strigosa); rye (Secale cereale); oilseed radish (Raphanus sativus); rye + oilseed radish; black oats + oilseed radish, and a control with spontaneous plants. Additionally, two plots, a conventional tillage system area and a forest, both adjacent to the experiment, were evaluated. We measured cover crop biomass, onion yield, acid phosphatase activity, and resin-extracted phosphorus in the soil, shoot and root phosphorus content, and root colonization in cover crops, spontaneous plants, and onions. The treatments with cover crops had the highest plant biomass in winter and onion yield. Available soil phosphorus and acid phosphatase activity were higher in no-tillage plots than in the conventional tillage system area. The presence of non-mycorrhizal oilseed radish was associated with decreased colonization of rye and onion roots by arbuscular mycorrhizal fungi. No-tillage areas with cover crops or spontaneous plants in winter accumulated more phosphorus than conventional tillage system areas. The conventional tillage system showed adverse effects on most soil attributes, as shown by a Principal Component Analysis.

ABSTRACT: The objective of this study was to evaluate the acute effects of ropivacaine hydrochloride on the corneal endothelium of horses. Forty-eight eyes were obtained from a commercial slaughterhouse and were randomly divided into three groups. In group A, the corneal endothelium was exposed to 0.75% ropivacaine hydrochloride for 60 seconds. In group B, the corneal endothelium was exposed to 0.75% ropivacaine hydrochloride for 15 minutes. In group C, the corneal endothelium was exposed to a balanced saline solution for 60 seconds. Afterwards, all samples were prepared for evaluation with scanning electron microscopy. Random electromicrographs were obtained from each sample. The images were analysed and, with the aid of software, areas with no endothelial cells were measured. The average endothelial loss, expressed as a percentage in relation to the total area, of the samples in group A was 5.28%. The average endothelial loss of samples from group B, expressed as a percentage in relation to the total area, was 20.39%. The damage to the corneal endothelium was significantly greater in group B compared to groups A and C. It was possible to conclude that 0.75% ropivacaine hydrochloride induced acute damage to corneal endothelium cells.
The health workforce demand: a systematic literature review
Authors: Lopes Diana Fernandes , Ramos Ana Luísa , Castro Eduardo Anselmo de
Published: June 2021

Abstract Understanding imbalances between the supply and demand of the human resour- ces for health (HRH) is essential for enhancing health outcomes. Addressing the HRH demand is particularly challenging, especially given the deficit of accurate data and surplus of unresolved methodological flaws. This study presents a systematic review of the literature surrounding HRH demand and answers the following key questions: How has HRH demand been addressed? What are the harms and barriers that accompany HRH demand modeling? This systematic review was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) statement. Relevant keywords were used in a thorough search of the PubMed/MEDLINE, SCOPUS, and Web of Science databases. A total of 2,599 papers were retrieved and evaluated according to their title and abstract. Of these, the full-text of 400 papers was analyzed, 53 of which successfully met the inclusion criteria in our study. While the topic’s relevance is widespread, it still lacks a validated approach to model HRH demand adequately. The main characteristics of the applied methods are presented, such as their application complexity by health policymakers. Opportunities and orientations for further research are also highlighted.
A new formula for managing family doctors’ patient list in Portugal
Authors: Maricoto Tiago , Nogueira Rui
Published: June 2021

Abstract In Portugal, family doctors work with a well-defined list of patients to whom they provide healthcare throughout their lives. Several studies showed that larger list sizes are associa- ted with poorer health outcomes and compromise the quality of care. A significant increase in the average list size has been observed in recent years due to the Portuguese unfavorable socioeconomic context and the lack of family doctors. In 2017, the Portuguese Association of General and Fa- mily Medicine (APMGF) developed technical and scientific research that ultimately typified a set of different clinical practice contexts. It considers the geographic and socioeconomic characteristics and a set of population-based indicators, adjusting the list size according to the population’s specific needs. Such adjustments ensure health care services with better quality, safety, efficacy, and personalized to their features. In this paper, a brief review is made on this topic, focusing on the work developed by APMGF and its main results.
The role of the State, the private sector and the social sector in the different health political cycles in Portugal
Authors: Simões Jorge , Fronteira Inês
Published: June 2021

Abstract The Portuguese health system comprises three critical sectors: The State, which intervenes as a regulator of the entire system, and as a planner, provider, and financer of the National Health Service (NHS); the social sector, with a relevant intervention, mainly in continued care; and the private sector, with an essential role in the provision of some types of care. During the last forty years, the State, social, and private sectors’ roles have changed either in its definition or terms of the relationship between them. In general, it is possible to identify, and we shall present them in this opinion article, eight political cycles that reflect the political contexts in Portugal, and, consequently, the ideological framework of each cycle.
