Authors: Ravani Swati A , Agrawal Garima A , Leuva Parth A , Modi Palak H , Amin Krisha D
Published: June 2021

Purpose:

Rhino-orbital mucormycosis in times of ongoing COVID-19 pandemic.

Aims:

The aim of the study was to document cases of rhino-orbital mucormycosis seen at our Regional Institute of Ophthalmology during COVID-19 (coronavirus disease 2019) times.

Methods:

The study is a retrospective, institutional cohort, interventional study. It was carried out at our Regional Institute of Ophthalmology from September 2020 to mid-March 2021. All patients of biopsy-proven mucormycosis were enrolled in the study. The patients were subjected to complete history taking, ophthalmological examination, and imaging studies. The patients were treated via a multidisciplinary approach with intravenous liposomal amphotericin B and debridement of local necrotic tissue. Exenteration was done when indicated. A minimum 75-day follow-up period was accorded to all study patients. Statistical analysis was done using Chi-square test. A P value ≤0.05 was taken as significant.

Results:

Thirty-one patients were seen, with a mean age of 56.3 years. The major risk factors included uncontrolled diabetes (96.7%) and COVID-19 positivity (61.2%), with concomitant steroid use in 61.2% patients. The most common presentation was diminution of vision (<6/60 in 80.64% patients) and ophthalmoplegia (77.4%). The most common imaging findings were orbital cellulitis (61.29%) and pansinusitis (77.4%). Intravenous liposomal amphotericin B was given to all patients for an average 18.93 days. Exenteration was required in (n = 4) 12.9% of cases. Twenty-eight patients recovered and were alive on follow-up. Mortality was seen in three patients. The presence of cerebral involvement and a HbA1c value of ≥8 were found to be significant in the prediction of survival of patients with mucormycosis.

Conclusion:

We present the largest institutional cohort of rhino-orbital mucormycosis patients during the ongoing COVID-19 pandemic era from our unique perspective.
Immediate sequential bilateral cataract surgery and its relevance in COVID-19 era
Authors: Bhalla Jatinder S , Zakai Mohmad Uzair , Mehtani Amit
Published: June 2021

Immediately sequential bilateral cataract surgery (ISBCS) involves performing phacoemulsification with intraocular lens implantation in both the eyes of a patient, sequentially in the same operative sitting. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. As a result of the COVID-19 pandemic, all elective surgeries were stopped. This has resulted in a large backlog of deferred cataract surgeries. Now more than ever before, we should consider ISBCS as an excellent alternative to delayed sequential bilateral cataract surgery in the right hospital or surgical setting. In the age of COVID-19, it can help to decrease surgical scheduling and follow-up visits. The one change in practice that could have the most significant benefit in reducing infection exposure risk is ISBCS.

Authors: Assiri Hassan Ahmed , Alkhaldi Yahia Matter , Alsaleem Safar Abadi , Alqarni Hassan Mohammad
Published: June 2021

Objectives:

This study aims to explore knowledge, attitude and practices of physicians working at primary health care (PHC) in Abha, KSA, regarding assessment and management of acute bronchial asthma.

Subjects and Methods:

This is a cross-sectional study that was conducted among PHC physicians in Abha, Khamis Mushayt and Ahad Rufeida cities, Aseer region KSA in 2018. A questionnaire that was constructed by the investigators was used to assess the knowledge, attitude and practices of PHC physicians regarding the diagnosis and management of patients with acute asthma. The questionnaire was distributed under the supervision of the first investigator. Data management was carried out using SPSS version 23.

Results:

A total of 200 PHC physicians participated in this study. About two-thirds of them (63.5%) had good grade of knowledge regarding acute asthma management, whereas 44% had positive attitude toward acute asthma management. The main knowledge gaps were doses of drugs used in the management of acute severe asthma attack (36%), and diagnosis of acute severe asthma attack (51.5%). Physicians' main source of knowledge on asthma included textbooks (26%) and guidelines (61.5%). Physicians' practice grades were significantly higher among those with less experience in PHC (p = 0.011). Almost all PHC centers (PHCC) (98%) had oxygen and nebulizers, 72.5% had steroids, 71.5% had salbutamol, 50.5% had ipratropium and 41% had peak flow meter, whereas 73.5% had the Saudi Initiative for Asthma (SINA) guidelines.

Conclusion:

This study revealed that knowledge of PHC physicians regarding the management of bronchial asthma was suboptimal, their attitude is not completely positive, and their adherence to asthma management guidelines is quite low. Some PHCCs were lacking important drugs and equipment for management acute asthma that should be provided. Well-structured training of PHCC doctors on SINA is mandatory to upgrade their knowledge, promote their attitude and improve their skills.

Published: June 2021

Respiratory infections like influenza infections have been found to increase the risk of coronary artery disease and precipitate cardiac failure. However, Indian data is lacking. A retrospective observational study was done to describe patients with influenza infection who had concomitant heart failure (HF) requiring admission over 5 years (January 2013-December 2017). A total of 93 influenza cases were hospitalised during this time, of which 14 (15%) also had features of HF. Among them, the types of influenza infection were AH1N1 (6,43%), BH1N1 (4,29%), AH3N2 (3,21%) with one patient having both strains. Two-thirds of the HF were new onset (10, 71%), whereas rest were due to acute worsening of pre-existing HF (4, 29%). Ten (64.3%) of the patients had HF with reduced ejection fraction (HFrEF). The average hospital stay was 10 days with 2 (14%) deaths. The peak of influenza in August and September preceded the peak admission for HF. A total of 15% of influenza admissions have concomitant HF. They are predominantly due to influenza A H1N1 (43%), influenza A H3N2 (21%) and influenza B (29%). Only 7% had preceding influenza vaccination. Influenza during August and September appears to precede the peak of HF admissions which happen in October and November. Overall mortality was 14%
Asymptomatic Bacteriuria (ASB) in diabetic patients
Authors: Tauseef Abubakar , Zafar Maryam , Syyed Erum , Thirumalareddy Joseph , Sood Akshat , Mirza Mohsin
Published: June 2021

Background:

The term asymptomatic bacteriuria (ASB) refers to the isolation of bacteria in a urine specimen of individuals who denied symptoms of urinary tract infection. Diabetes mellitus (DM) is a disease involving multiple organ systems, hallmarked for its chronicity and thus-forth endless complications including asymptomatic bacteriuria.

Objectives:

This study aimed to determine the characteristics of asymptomatic bacteriuria and antibiotic susceptibility pattern amongst patients with diabetes.

Settings and Design:

A prospective observational study was conducted at a tertiary care hospital in Karachi, Pakistan.

Methods and Material:

The study included all those patients with a diagnosis of diabetes with no signs and symptoms of urinary tract infection but showing the growth of an organism in urine culture. Pregnant females and subjects who used antibiotics in last two weeks were excluded. A total of 222 urine cultures were observed prospectively who met the inclusion criteria through non-probability consecutive sampling.

Results:

Out of 222 urine cultures observed, mean age of subjects were 62.89 ± 13.77 out of which 76% were females, and 61% had a family history of diabetes. The most frequent organisms isolated were Escherichia. Coli (E. Coli), Enterococcus, Klebsiella, Pseudomonas, and Enterobacter species. A total of 20 subjects got dual bacterial growth in their cultures among which 17 subjects had a growth of Enterococcus with any other pathogen causing UTI. Gender, family history of diabetes, levels of HBA1c, and older age groups all were found significantly associated with ASB.

Conclusions:

Our study is the first to analyze and study the associated risk factors amongst ASB in DM patients, and to identify the pathogens involved along with assessing their antibiotic resistance profiles. Also, due to the increase resistance to antibiotics we would recommend to use antibiotics in ASB patients only if they have any two or more comorbidities.

Authors: Mukhopadhyay Kaushik , De Soumita , Kundu Sunanda , Ghosh Parasar , Chatterjee Suparna , Chatterjee Mitali
Published: June 2021

Objectives:

One of the most prevalent autoimmune disease globally, rheumatoid arthritis (RA) is caused by interplay of multiple inflammatory mediators in specific joints. Altered redox balance is one of the key factors in pathophysiology of RA. This study aims to find whether oxidative stress in peripheral blood neutrophil correlates with the disease activity and disability associated with it.

Methods:

Ten healthy controls and 29 RA patients with moderate to severe disease activity (DAS28 score >3.2) were recruited and reactive oxygen species (ROS) level in peripheral blood neutrophil was measured using flow cytometry at baseline visit and after 6 months follow-up. Functional status of RA patients was measured using Health Assessment Questionnaire Disability Index (HAQ-DI).

Results:

RA patients showed significantly higher level of ROS in compared to healthy control. DAS28 correlated well with ROS at baseline visit (Pearson's r = +0.63) as well as follow-up visit (Pearson's r = +0.75). HAQ-DI showed weak positive correlation at baseline visit (Pearson's r = 0.1) but it was negative at follow-up visit (Pearson's r = -0.19).

Conclusions:

Oxidative stress mirrors the disease activity in RA and can be considered as a biomarker, but it is not related with functional ability of the patients.

Authors: Chopra Deepti , Bhandari Bharti , Dwivedi Shridhar
Published: June 2021

Coronavirus disease 2019 (COVID-19) pandemic has had a severe impact globally. As of now, very little is available for the cure of this disease. The rapid increase in the number of confirmed cases makes prevention and control extremely important. In view of the success of traditional Indian medicine drugs during the several epidemics in the past, it is logical and essential to examine the contributions of the Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homeopathy (AYUSH) in managing the COVID-19 pandemic. The Indian traditional medicines interventions are well known and have several potential drug candidates that can be used as an add-on therapy along with current modern drugs. Herbal medicines containing bioactive compounds that possess anti-inflammatory, anti-pyretic, anti-viral, and immune-modulating properties like Tinospora cordifolia, Ocimum sanctum, Allium sativum, Citrus limon can be explored as therapeutic agents for COVID-19. Health-promoting immunomodulators like Withaniasomnifera, Tinospora cordifolia, Piper longum, Glycyrrhiza glabra may improve host defense and could be an effective prophylaxis approach against COVID-19. The present mini-review is aimed to survey and introduce important medicinal herbs and plants which can be used against Covid-19.

Courant-sharp property for Dirichlet eigenfunctions on the Möbius strip
Authors: Bérard Pierre , Helffer Bernard , Kiwan Rola
Published: June 2021

The question of determining for which eigenvalues there exists an eigenfunction which has the same number of nodal domains as the label of the associated eigenvalue (Courant-sharp property) was motivated by the analysis of minimal spectral partitions. In previous works, many examples have been analyzed corresponding to squares, rectangles, disks, triangles, tori, .... A natural toy model for further investigations is the Möbius strip, a non-orientable surface with Euler characteristic 0, and particularly the ‘‘square’’ Möbius strip whose eigenvalues have higher multiplicities. In this case, we prove that the only Courant-sharp Dirichlet eigenvalues are the first and the second, and we exhibit peculiar nodal patterns.
Including Explicit Priors on Phase Duration in Bayesian 14C Dating
Authors: Yanovich Igor
Published: June 2021

Bayesian modelling of radiocarbon dates directly integrates information obtained through archaeological analysis. Here, I explain how to add known information/reasonable assumptions about the length of a deposition phase, using the example of date sequences from two Early Neolithic communities in the Aegean whose dating has been hotly debated, i.e. basal Knossos (Crete) and Nea Nikomedeia (Northern Greece). The consequences of the re-evaluation of their dates are discussed for the broader picture of the Neolithisation in the Aegean and for the chronology of the regional use of stamps.

Comercio, sobreexplotación laboral y ciclos en la periferia: una propuesta teórica y el caso ecuatoriano desde un modelo PVAR
Authors: Cajas-Guijarro John , Pérez-Almeida Bryan
Published: June 2021

El presente artículo interpreta teóricamente cómo la competencia real capitalista internacional presiona a que en las sociedades periféricas los balances comerciales dependan de ventajas absolutas de costo basadas en una sobreexplotación laboral-natural, lo que crea dinámicas cíclicas en dichas sociedades. Para reforzar tal interpretación, el artículo toma como caso de estudio al capitalismo periférico ecuatoriano, sobre el que se presentan tendencias histórico-cíclicas de mediano y largo plazo, ejemplos de actividades económicas que al parecer sustentan sus superávits comerciales desde la sobreexplotación laboral-natural, y evidencia estadística de tendencias cíclicas de corto plazo a nivel sectorial, estimando un modelo PVAR sobre un panel de datos compuesto por 43 actividades económicas observadas en el período 2007-2016. Todos los resultados empíricos muestran la importancia de las ventajas absolutas de costo basadas en la sobreexplotación sobre los balances comerciales y el surgimiento de ciclos que refuerzan la condición dependiente del capitalismo ecuatoriano.

Authors: Solano Sanchez Miguel Ángel , Núñez Tabales Julia M. , Caridad y Ocerin José M.
Published: June 2021

El auge de los nuevos tipos de alojamiento denominados alquileres turísticos (apartamentos turísticos y viviendas con fines turísticos) experimentado en los últimos años a nivel mundial, gracias a la expansión de Internet y las redes P2P, despierta el interés por el análisis de estas nuevas fórmulas de estancia. El objetivo de este estudio es la elaboración de un modelo a través del método de precios hedónicos (MPH) que establezca cuáles son las variables fundamentales en la determinación del valor diario de la estancia en alquileres turísticos. Dicha metodología, ha sido ampliamente usada en valoración inmobiliaria y determinación del precio en alojamientos turísticos (mayoritariamente hoteles), aunque se encuentran pocos trabajos en lo que respecta a su uso para valoración de alquileres turísticos. A partir de los datos recogidos sobre Sevilla -la mayor ciudad del sur de España- se obtiene un modelo econométrico para valoración de alquileres turísticos en el que destacan como principales variables explicativas del mismo la ubicación del inmueble, el tamaño, el equipamiento, así como el momento del tiempo en que es tomado el precio. Los resultados del presente estudio pueden resultar de interés tanto a propietarios como a potenciales clientes de alquileres turísticos, para conocer si el precio de la estancia está en concordancia con lo que normalmente ofrecería el mercado en esas circunstancias.

Government-Opposition Relations during Benazir Bhutto’s Rule in Pakistan
Authors: Rehman Ashfaq U. , Khan Arif , Khan Bakhtiar
Published: June 2021

Democracy, transition to democracy and democratic consolidation have widely been debated across the world and have prominent position in third world countries. Democracy in developing countries particularly in Pakistan is confronting long standing problem of consolidation of power by civilians. In democracy the strength of the state institutions depends on the relationship among central government with opposition and with provincial governments. Pakistan consists of a centre and four federating units having mix nationalities. This paper investigates the factors which have provoked confrontational politics both within the parliament between ruling and opposition parties and with provincial governments especially Punjab during Benazir Bhutto’s rule. The paper focuses on the question whether it was the same follies which Benazir Bhutto played with during her second term with opposition in the centre and their governments in provinces. To find answers to these questions, secondary data has been used and to supplement newspapers have been consulted for obtaining first-hand information of public officials. The relationship among the ruling party in the centre with opposition and the provincial governments often remained unpleasant and unfriendly. It is argued that personal the national considerations augmented the confrontation and conflicts among national and regional level political parties.
Tasavvuf ve Hanbelî Gelenek: Kādî Ebū Yaʿlâ el-Ferrâ’nın Tasavvufa Yaklaşımı Bağlamında Bir Değerlendirme
Authors: BAŞER Hacı Bayram
Published: June 2021

Tasavvufun İslâm toplumunda yaygınlaştığı erken dönemdeki gelişmeleri anlamak, tasavvuftan diğer disiplinlere yönelik çalışmaları zorunlu kıldığı gibi, diğer dinî ilimlerden tasavvufa bakışın da ele alınmasını gerektirmektedir. Bu kapsamda dikkati çeken isimlerden birisi de ünlü Hanbelî âlim Ebū Yaʿlâ el-Ferrâ’dır (ö. 458/1066). Ebū Yaʿlâ el-Ferrâʾ hadis, fıkıh ve tefsir ilimlerinin yanı sıra tasavvufî ve kelâmî konularla ilgilenerek bu alanda yazdığı eserlerle bilhassa Hanbelî geleneği içerisinde önemli bir yere sahiptir. Ehl-i sünnet kelâm mekteplerinin teşekkül edip yaygınlaştığı ve tesirini icra ettiği bir dönemde yetişen Ebū Yaʿlâ, Hanbelî bakış açısını korumakla birlikte kelâm metodunu kullanarak hem bazı kelâm ekollerini hem de sûfîleri eleştirmiştir. Dolayısıyla onun görüşlerini tahlil etmek, ilk dönem dinî ilim geleneğinin teşekkül şartlarını anlamak bakımından önem arz ettiği gibi tasavvuf ve Hanbelî gelenek arasındaki ilişkiye dair de ipuçları verecektir. Bu makalede Ebū Yaʿlâ’nın Kitâbu’l-Muʿtemed ve Kitâbü’t-tevekkül eserlerinde onun zühd, tasavvuf ve tevekkül anlayışı irdelenmekte, tasavvuf ve Hanbelî gelenek arasındaki ilişkiyi anlamadaki önemi vurgulanmaktadır.

Authors: S. M. Attiogbe , L. Adetunde , S. A. Abagale
Published: June 2021

Chewing of nuts of Cola acuminata is a cultural practice in any African countries especially Ghana and Nigeria. The current study investigated antibacterial activity and phytochemical composition of methanol and ethanol Soxhlet extracts of raw, steamed and roasted cola nut on Pseudomonas aeruginosa and Staphylococcus aureus using the agar well diffusion method. Amoxillin and distilled water were used as controls. The ranges of mean zones of inhibition of the methanol and ethanol extracts of raw cola nut at 200mg/ml tested against Staphylococcus aureus and Pseudomonas aeruginosa were 10.00±0.00 to 15.00±0.00 and 10.50±1.50 to 12.00±0.00 respectively. The ranges of the mean zones of inhibition of the methanol and ethanol extracts of steamed cola nut at 200mg/ml tested against Staphylococcus aureus and Pseudomonas aeruginosa were 8.00±0.00 to 7.00±0.00 and 7.50±0.50 to 8.50±0.50 respectively. Those of the methanol and ethanol extracts against Pseudomonas aeruginosa and Staphylococcus aureus were 6.00±0.00 to 7.00±0.00 and 5.00±0.00 to 6.00±1.00 respectively. Raw cola nut was found to be most effective against the two microbes. However, Amoxicillin at concentration 200mg/ml presented the highest mean zones of inhibition against Staphylococcus aureus (36.00±0.00) and Pseudomonas aeruginosa (29.00±0.00), while distilled water had no inhibitory on the two microbes. Extract concentrations from 120–30 mg/ml had similar trends of inhibition with the 200mg/ml concentration. Phytochemical screening revealed the presence of saponins, terpenoids, alkaloids, tannins, flavonoids and phenols in both methanol and ethanol extracts of the raw, steamed and roasted cola nut.

The modern person lives in conditions of a new environment in which the share of a natural basis is reduced. There is a falling interest of young generation to studying and research of the nature. The modern environment is multicomponent system. The natural, public and modified components are included in the structure of the environment.
Teaching / learning subjects of a school natural science cycle – biology, geography, physics and chemistry have connections not only in the theoretical plan, but also a uniform basis of the empirical character (scientific supervision, measurement, experiment etc.). The interaction of the theory and practice during knowledge of an environment enables pupils to analyze the World as a whole. The combination of pupils' knowledge and their dialogue with natural objects in a concrete and real environment, allows them not only to observe, describe and analyze different situations, but also to predict and design further development of such situations.

The study's findings show that among the green initiatives implemented by SMMEs, which resulted in the reduction of total costs and expenses, were the proper disposal and segregation of waste materials, water management by recycling wastewater and using water-efficient equipment, natural resources, and raw materials management.  SMMEs should encourage active participation and support of suppliers and customers in achieving G.E.D.'s objectives by developing incentive schemes. Furthermore, SMMEs should continue to benchmark with G.E.D. Practitioners are operating locally and abroad to adopt best greening strategies and regularly network with concerned government agencies for continuous updating on G.E.D. Initiatives that may benefit the firm.  Further research may be conducted on green initiatives implemented by small and medium enterprises in other industry sectors.
Design and Development of a Genetic Algorithm Based on Fuzzy Inference Systems for Personnel Assignment Problem
Authors: Rabiei Peyman , Arias-Aranda Daniel
Published: June 2021

In today’s competitive markets, the role of human resources as a sustainable competitive advantage is undeniable. Reliable hiring decisions for personnel assignation contribute greatly to a firms’ success. The Personnel Assignment Problem (PAP) relies on assigning the right people to the right positions. The solution to the PAP provided in this paper includes the introducing and testing of an algorithm based on a combination of a Fuzzy Inference System (FIS) and a Genetic Algorithm (GA). The evaluation of candidates is based on subjective knowledge and is influenced by uncertainty. A FIS is applied to model experts’ qualitative knowledge and reasoning. Also, a GA is applied for assigning assessed candidates to job vacancies based on their competency and the significance of each position. The proposed algorithm is applied in an Iranian company in the chocolate industry. Thirty-five candidates were evaluated and assigned to three different positions. The results were assessed by ten staff managers and the algorithm results proved to be satisfactory in discovering desirable solutions. Also, two GA selection techniques (tournament selection and proportional roulette wheel selection) were used and compared. Results show that tournament selection has better performance than proportional roulette wheel selection.
Estratigrafía, paleoambientes y correlación del Paleozoico Superior en la localidad Río Francia, Cuenca Paganzo, Argentina
Authors: Correa Gustavo , Gutiérrez Pedro Raúl
Published: June 2021

The Tupe and Patquía formations are known for their marine, deltaic, river, and eolian deposits that record different Late Paleozoic events in the Paganzo Basin. However, in the area of the Río Francia (Province of San Juan, Argentina), these units are relevant because they are located in a strategic place of connection with the southernmost sedimentary sequences in the Paganzo Basin on the Central Precordillera. The Tupe Formation (which by palynological data would represent the late Serpukhovian-Gzhelian interval) has a minimum thickness of 140 m of bioturbed mudstones with a minor percentage of coarse to fine sandstones intercalated. In this work they are grouped into 3 facies associations: I lagoon; II barrier island and III shoreface. The Patquía Formation (from palynological data, in this locality, of Cisuralian in age), it is a typical succession of red beds with deposits of fine -grained sandstones with cross-bedding, and alternation of sandstones with mudstones. 3 facies associations were differentiated: IV anastomosed fluvial; V eolian and VI playa lake. A correlation analysis between these formations and their lithostratigraphic equivalents provided possible scenarios for the western sector of the Paganzo Basin, showing a lineament of units with coastal environment features for the Tupe Formation and equivalents at these latitudes.

For any insurance contract to see the light of day, a particular process flow is usually followed. This process flow begins with the customer calling an agent to obtain insurance, and ends with the customer receiving a quote for the coverage. Precision methods focus on improving precision and quality and on planning measures that absolutely address issues and meet the necessary requirements. Unlike automation where the focus is on speeding up tasks and processes, a precision-based approach is centered around improving the quality of the process. More current practices call for ceaselessly examining and retooling tasks/operations to achieve ever more noteworthy business esteem. In this paper, the Insurance Policy Administration System is covered in detail. The format, layout, and key details that the insurance policy entails are thoroughly covered. Some key functionalities like The Policy Submission, Risk Analysis, Policy changes and renewals, Policy cancellation in a typical Policy Administration System are reviewed. Since the Policy Administration System cannot be a standalone service and has to be used along with external systems, the integration of this typical policy administration system with an external system like a user management system is also discussed.

Thiếu hormon tăng trưởng là nguyên nhân thường gặp gây tầm vóc thấp, được điều trị bằng phác đồ thay thế hormon tăng trưởng tái tổ hợp tiêm dưới da. Bệnh nhân thường đạt được vận tốc chiều cao tối đa trong năm đầu điều trị, sau đó sẽ giảm dần trong những năm sau cho đến khi ngừng điều trị. Mục tiêu: nhận xét kết quả điều trị lâu dài ở các bệnh nhân sử dụng GH tái tổ hợp. Đối tượng và phương pháp: nghiên cứu một loạt ca bệnh bao gồm 3 bệnh nhân thiếu hụt hormon tăng trưởng được bắt đầu điều trị hormon tái tổ hợp thay thế ở tuổi 47 tháng và 75 tháng. Tất cả bệnh nhân tại thời điểm bắt đầu điều trị đều có tầm vóc thấp (< - 4SD theo tuổi và giới), nồng độ IGF1 thấp hơn so với chuẩn, tuổi xương thấp hơn so với tuổi thực. Phim chụp MRI sọ não không phát hiện khối bất thường. Đối với ca bệnh đầu tiên, trẻ được làm test kích thích hormon tăng trưởng với glucagon và kết quả nồng độ GH đỉnh thấp 0.024 ng/ml. Phác đồ hormon thay thế đã được điều trị trong vòng  3- 5 năm. Kết quả: tốc độ tăng chiều cao được cải thiện sau điều trị: 14 - 18 cm trong năm đầu tiên, giảm dần trong các năm tiếp theo. Trẻ bắt kịp tốc độ tăng trưởng bình thường theo WHO sau 3 năm điều trị. Kết luận: tầm vóc thấp là triệu chứng lâm sàng chính. Điều trị hormon thay thế sớm trên trẻ bị GHD giúp trẻ có được tốc độ tăng trưởng chiều cao bình thường.

A preocupação com a sustentabilidade contribuiu para o aparecimento de práticas empresariais que ficaram conhecidas como gestão ambiental e que visam reduzir riscos e impactos ambientais negativos. Para legitimar isso, as empresas buscam divulgar informações sociais nos relatórios anuais de administração, o que pode servir para mitigar a intervenção política, pois gestores podem decidir acerca da quantidade e da natureza da evidenciação social e ambiental que a empresa faz. Entre as formas de divulgação dessas práticas de sustentabilidade, diversas empresas têm priorizado os Relatórios da Administração (RA). Nesse sentido, esta pesquisa tem o objetivo de identificar as estratégias de legitimidade da tipologia de Suchman (1995) que a companhia de mineração Vale S. A. mencionou nos seus relatórios da administração no período de 2010 a 2016. Para atingir o objetivo proposto foi utilizada metodologia de cunho exploratória, com base numa análise documental e abordagem qualitativa. Foram analisados os Relatórios da Administração publicados pela companhia nos anos citados, centrando-se a atenção em relação aos critérios “ganho”, “manutenção” e “reparação”, sendo identificadas 1.647 menções relacionadas com a legitimidade. Constatou-se que o critério “ganho” apresentou a maior quantidade de itens presentes nos relatórios dos sete anos abrangidos, com 51,67% das citações. Por outro lado, ao se considerar as estratégias de legitimidade geral, pragmática, moral e cognitiva, os resultados demonstram que a estratégia geral foi a mais citada, seguida pela cognitiva, pragmática e moral, respectivamente. Quanto às possíveis contribuições do estudo, considera-se que o aspecto mais relevante está ligado ao comparativo efetuado com estudos realizados em outras empresas (nacionais e estrangeiras), o que permite comparações nas formas de conduta de suas atividades relacionados à legitimidade.

O objetivo deste estudo foi realizar uma proposta de implementação do custeio baseado em atividades na gestão de serviços funerários. A pesquisa se caracteriza como um estudo de multi-casos, de caráter descritivo e exploratório, com uso de um roteiro de entrevista. A proposta de implementação do ABC contempla quatro micro etapas: identificação das atividades; atribuição dos custos às atividades; identificação dos objetos de custos; e atribuição dos custos das atividades aos objetos de custos. Com os resultados da pesquisa foram possíveis identificar os custos indiretos, os recursos, as atividades e os principais direcionadores de custos para posterior análise dos serviços prestados. Apesar das limitações da pesquisa acerca do cálculo do valor de cada atividade, os resultados contribuíram para o desenvolvimento de futuros estudos referentes aos custos de serviços funerários, uma vez que pesquisas nesse tema são bastante escassas.
