Authors:   Doctor of Philosophy major in Educational Management, University of Perpetual Help System Laguna, Nacario-Arce Remilyn
Published: May 2022

This descriptive-correlational study investigated the relationship between the teachers’ use of higher-order cognitive skills, instructional skills in online science teaching and academic achievement of students in elementary science. The respondents of the study were 91 elementary science teachers who were randomly sampled from the 117 Grade 3-6 elementary science teachers of DepEd Division of the City of Sta. Rosa. The research instrument was validated by experts in the field and its internal consistency reliability was ascertained using Cronbach Alpha. The findings revealed that the teachers always used higher order cognitive skills in online science teaching (WM=3.28). They had very high level of instructional skills in online science teaching (WM=3.42.). Sixty-five (65) or 71.43 percent of the elementary science teachers reported an aggregated GPA of 85 to 89 for their classes; 18 or 19.78 percent had 80 to 84; and 8 or 8.79 percent got 90 to 94. There were no significant relationships between the respondents’ frequency of use of higher-order cognitive skills in online science teaching and the students’ academic achievement in elementary science (p>0.05); and between the respondents’ level of instructional skills in online science teaching and the students’ academic achievement in elementary science(p>0.05). It was concluded in the study that the teachers’ use of higher order teaching skills in online science teaching and their instructional skills have no bearing on the academic achievement of the students. A study on the correlation between higher-order skills of students and their academic achievement in elementary science may be conducted to verify this study’s findings and confirm the other studies’ findings.

Published: May 2022

Vanadyum doğada yaygın olarak dağılmış olan bir iz elementtir ve insan dahil neredeyse tüm canlı organizmalarda bulunur. Vanadyumun önemi insanlarda ve hayvanlarda hala net olmasa da, daha düşük konsantrasyonlarda mikroorganizmalar, bitkiler ve hayvanlar için gereklidir ve canlı organizmalardaki eksikliği birçok yan etkiyle ilişkilidir. İnsanlarda çok çeşitli farmakolojik özellikler sergileyen vanadyum, insülini taklit etme etkisinden dolayı diyabeti tedavi etmek için diyet takviyelerinin bir bileşeni haline gelmiştir. Vanadyum ayrıca plazmayı korur, kan hemoglobini, V eksikliğinden etkilenmez, ancak V eksikliği olan diyetler amino asit metabolizmasını değiştirmeden kreatinin, trigliseritler, β-lipoprotein ve enzim benzeri glutamil transferaz ve sitrat asit döngüsünün aktivitelerini arttırır. Kolesterol düzeylerini, kalp hastalığını, sifilizi, tüberkülozu, anemiyi ve ödemi azalttığı, hemoglobin ve miyoglobinin oksijen afinitesinin artırılmasında rol oynadığı, iyot metabolizması ve tiroid fonksiyonu için gerekli olduğu bildirilmektedir. Kemiklerde kalsiyum birikimini kolaylaştırırarak kemik kollajen sentezinde, osteojenik ve osteoblastik aktivite için gereklidir, serum lipid düşürme kabiliyetine sahiptir, diyabetik koşullarda potansiyel bir antioksidan ajan olarak hareket eder. Vanadyum bileşiklerinin immün regülasyonda rol oynadığı bilinmektedir ve gelecekteki immünoterapiye yönelik umut verici metal ilaçlar olarak kullanılabilir. Kardiyovasküler ve sinir sisteminde rol oynar. Anti-parazitik, anti-viral, anti-HIV, anti-tüberküloz, anti-bakteriyel ve anti-tümör ajanları olarak da rol oynar, ancak ortalama 90 mg/kg konsantrasyonda topraktaki vanadyum, potansiyel olarak tehlikeli kirletici olarak kabul edilmiştir. Yüksek seviyelerde önemli toksik etkiler yaratabilir. İnsanlardaki fazla vanadyum, böbreklerde, karaciğerde, dalakta, kemiklerde ve lökositlerde morfolojik ve fonksiyonel lezyon riskini artırabilir. Bu derleme makalemizde, vanadyumun sağlığımıza nasıl etkileri olduğunu incelemek ve yararının yanında doza bağımlı olarak toksik etkilerini araştırmak amaçlanmıştır.

Published: May 2022

Purpose: The purpose of the study was to investigate the effect of automated teller machines and mobile banking on financial inclusion among commercial banks in Somalia.

Methodology: A descriptive survey design was adopted targeting 6 commercial banks in Somalia that had successfully rolled out electronic banking while the respondents covered the Banks staff, like managers and officers from each institution respectively and census was used. Primary data was collected on automated teller machines, mobile banking and customer deposits with the aid of the questionnaire.  The analysis was conducted through the Statistical Packages for Social Sciences version 24 utilizing descriptive statistics (means and standard deviations) and inferential statistics (correlation and regression analysis) and presented through tables.

Findings: The study found out that automated teller machines banking and mobile banking are significant predictors of financial inclusion among commercial banks in Somalia. Thus, electronic banking is a significant enabler of financial inclusion of commercial banks.

Unique contributions to theory, practice and Policy: The study contributes to the extension of the views of financial intermediation theory and the diffusion of innovation theory. The study implies that the adoption of electronic banking as influenced by the diffusion of innovation theory allow financial institutions to effectively realize their financial intermediation role in the economy.  The senior management team of commercial banks in Somalia should allocate more resources towards financial innovation and enhancement of the existing electronic banking channels and infrastructures.  The policy makers at the Central Bank of Somalia need to develop progressive regulations and rules that would promote the adoption of financial innovation while boosting financial inclusion
A REVIEW ON FAST DISSOLVING TABLET
Authors: Ahmed Mohd. Salman , Upadhyay Nikita , Dubey P.K
Published: May 2022

Fast dissolving tablets (FDTs) emerged as one of the popular and widely accepted dosage forms. Few solid dosage forms like capsules and tablets are present days facing the problems like difficulty in swallowing (dysphagia) resulting many incidences of non-compliance and making the therapy ineffective. Specifically for paediatric patients because of incomplete development of the muscular and nervous system and case of geriatric patients suffering from Parkinson’s disorder. Oral dosage form and oral route are the most preferred administration route for various drugs with limitations like first-pass metabolism, bedridden, psychiatric patients and uncooperative patients. There is no need of excess water to dissolve and disintegrate FDT tablets. Fast dissolving tablets are designed to dissolve in within 60 seconds in saliva remarkably faster. FDTs formulations contain super disintegrants to enhance the disintegration rate of tablet in the buccal cavity. FDTs have disintegrated quickly, absorb faster so, in vitro drug release time improve and this property of drugs (dosage form) enhanced bioavailability. FDTs have advantages such as easy portability and manufacturing, accurate dosing, good chemical and physical stability and an ideal alternative for geriatric and paediatric patients. FDT formulations have advantage over both conventional tablets and liquid dosage form.

Oral route of Mouth dissolving film is the most advanced oral solid dosage form due which it is very much in use now a day because of it’s flexibility and comfort. Mouth dissolving films are oral solid dosage form that disintegrate and dissolve within few minutes when placed in tongue without taking water. This dosage form allows the medication to bypass the first pass metabolism, so that the bioavailability of medication can be improved .Mouth dissolving film has potential to improve onset of action lower the dosing and eliminate the fear of chocking. Formulation of mouth dissolving films involves both the visual and performance characteristics as plasticized hydrocolloids, API’s taste masking agents are being laminated by solvent casting and semisolid casting method. Solvent casting method being the most preferred method over other methods because it offers great uniformity of thickness and films prepared having fine glossy look and gives them the better physical properties. Mouth dissolving films are evaluated for its various parameters like dissolution time, disintegration thickness, physical property like folding endurance. This review gives an idea about formulation techniques, evaluation parameters, overview on packaging and some available marketed products of mouth dissolving films.

A sárgarépa, a burgonya és a zeller tisztítási vesztesége
Authors: Palkovics András , Finta Zita
Published: May 2022

A sárgarépa, a burgonya és a gumós zeller olyan zöldségnövények, amelyeket nagy mennyiségben használnak a termelés folyamán a vendéglátóiparban és a közétkeztetésben egyaránt. Ennek ellenére a gyakorlatban a konyhákon még mindig inkább kézi erővel tisztítják ezeket a gépi tisztításra is alkalmas zöldségeket. Azonban a gépi tisztítás gazdaságosabb és gyorsabb előkészítést eredményezhetne, amely nem elhanyagolható szempont, figyelembe véve azt, hogy a tisztítás fajtájától függően a hulladék mennyisége a feldolgozatlan nyersanyag mennyiségének 10-40%-át is kiteszi. Ebben a kutatásban a kézi és a gépi zöldségtisztításból származó veszteségeket és az ebből eredő gazdaságossági kérdéseket vizsgálom.
A munkahely-választási preferenciák és a munkavégzési szokásaink átalakulása a koronavírus hatására
Authors: Badinszky Réka Gabriella
Published: May 2022

A koronavírus az elmúlt két évben gyökereiben változtatta meg a munkavállalói attitűdöket és a korábbi HR gyakorlatokat. A munkáltatóknak szembe kell néznie a változásokkal, illetve reagálniuk kell a munkaerőpiaci változásokra. A munkavállalók számára munkahely-választásnál továbbra is az alapbér az elsődleges szempont és fontos a rugalmas munkarend és munkaidő. Azonban fontos kiemelni, hogy a vezetői közvetlen, nyílt és őszinte kommunikáció előtérbe került az online tér hódításával. A távmunkát végzők száma 2009-hez képest megháromszorozódott és 2020. tavaszán elérte a 760 ezer főt is. A primer kutatás eredménye alapján elmondható, hogy a felmérésben résztvevők csupán közel egyharmad részének nem elérhető semmilyen formában az otthonról történő munkavégzés. Jelen tanulmány célja a dolgozók munkahelyválasztási preferenciáinak felmérése és a bekövetkezett változások bemutatása egy kérdőíves vizsgálat eredményei alapján.

Published: May 2022

The frequent removal of sediment accumulation from reservoirs by dredging requires interruption of power generation. Alternatively, this can be avoided by using a slit weir. In the present study, the impact of sediment nonuniformity, slit weir dimensions, weir slit position, and discharge on the effectiveness of sediment removal was experimentally investigated using a flume with a length of 12m, a width of 0.30m, and a depth of 0.30m. In the flume, a slit weir was tightly fixed at the end of a 2m working section filled with nonuniform sediments up to 110mm. Results showed that using coarser sediment (d50 = 0.70mm) reduces the scour volume by 22-folds compared to finer sediment (d50=0.30mm). This study tested five different slit weir dimensions using two weir slit positions (slit positioned in the center and slit positioned on the side). The maximum scour volume was recorded when the crest level, z of the slit weir, was 0 cm from the mobile bed. The study concluded that a 3-fold increase in discharge corresponds to a 10-fold increase in scour volume regardless of bed material nonuniformity. The existing model for estimating scour volume for uniform sediments was validated using the data of this study, and it was observed that the model predicts the scour volume in nonuniform sediments with sufficient accuracy. Thus, the model can determine the scour volume, and maximum scour depth occurring upstream of a slit weir near a hydropower intake in reservoirs.

Authors: Massey Stephi Grove
Published: May 2022

A quantitative research approach with experimental research design, with pre-test and posttest control group design and multiple time series design in this study. The purpose was, to assess the effectiveness of the video assisted teaching module was evaluated in terms of the knowledge gain on polycystic ovarian syndrome among 480 samples from a total of 652 over-weight women diagnosed with polycystic ovarian syndrome in selected hospitals of Madhya Pradesh. The subjects were randomly divided into two groups of equal size of 240 each using lottery method. On the 7th month of data collection sample size reduced from 240 to 210 in experimental and control group 210. The pre-test knowledge of over-weight women diagnosed with PCOS showed that majority of them had poor (50.95%), 48.80 percent of them had average and only 0.5% of total selected over-weight women had good knowledge scores. In the pre-test attitude of over-weight women diagnosed with polycystic ovarian syndrome was evaluated. 90.5 percent women’s attitude towards polycystic ovarian syndrome was strongly unfavourable, 9.05 percent had unfavourable attitude and only 1.0 percent of total selected over-weight women had favourable attitude towards polycystic ovarian syndrome. Experimental and control group comparisons was carried out to identify the differences in improvement of knowledge. Before administration of video-assisted teaching module, 92.4 percent had strongly unfavourable, after administration no one was found in this grade. 7.6 percent had unfavorable attitude regarding polycystic ovarian syndrome before administration of video-assisted teaching module but after administration post-test attitude data showed that none (0.0%) were over-weight under unfavourable attitude category. There was signi cant association between knowledge and demographic variables at 0.05 level of signi cance with the demographic variables of: educational quali cation, menstrual cycle, exercise habits and BMI status. Over-weight women with PCOS do not have adequate knowledge, or an appropriate attitude towards their diagnosed disease, whereas post intervention the knowledge score and attitude both were good, positive and favourable.

As longevity increases, the population of menopausal age group women is rising in India as elsewhere. According to the Indian Menopausal Society, the number of menopausal women is around 43 million. Fortunately, menopause is now better understood and more openly discussed than ever before. This study sought to assess and compare the effect of Yoga on somato-vegetative menopausal symptoms of women before and after administration of Yoga between Yoga and Non–Yoga groups and to associate the post-test somato-vegetative menopausal symptoms with the selected demographic variables in two groups. It had a true experimental design involving random assignment to treatment group and control group. The study was conducted between June 2015 and July 2016 among menopausal women coming in selected Sub Centres in two Primary Health Centres. The sample size was 120 each in Yoga group and Non-Yoga group. There were 12 drop outs in the Yoga group. The study adopted cluster sampling technique with randomisation. Majority (61.1%) of them experienced mild somato-vegetative symptoms and signi cant (34.3%) of them experienced moderate level of somato-vegetative symptoms after post-test in the Yoga group. The study showed a reduction in menopausal somato-vegetative symptoms in Yoga group of menopausal women thus proving Yoga intervention to be effective. Women in menopause showed a positive attitude towards performing Yoga as they found it safe in their home settings.
Analyzing Factors Responsible For Non- Acceptance of Hearing Aids
Authors: Niyogi Anjan , Kumari Pallavi
Published: May 2022

Hearing loss relates to missing certain sounds. The problem is certain sounds in the hearing nerve in our brain do not get enough stimulation. The nerves need stimulation. When it is not stimulated, the nerve stops working. When the nerve stops working, there arises complexity in our hearing nerves, which processes sounds that we hear. Similar to exercising which we do to keep your body healthy, our ears also need to hear sounds and recognize them to function at its best. So, the longer waiting time prior to hearing aids purchase, or to wear them, the less stimulation the brain and hearing nerves get. The speech recognition becomes worse. Studies by WHO shows that nearly 40% of the age group in between age group 55-74 yrs (McCormack A. & Fortnum H., May2013) suffers from this type of problem. If we compare with vision impairment Hearing Impairment users do not take this matter quite seriously. The problem of Hearing Loss is not only restricted to senior citizens but all age groups. Once the nerve is affected, there is no way to reverse the damage. There are also other side effects of not wearing Hearing aids. These include higher risk of cognitive decline, forgetfulness, depression, low performance at work leading to income, less productivity and the list goes on. The factors which responsible for non-acceptance are not single but rather they are multi faced. Starting from financial problems, Physical looks, Perception, discomfort, are some of the few reasons. In this paper has tried to identify the factors which are responsible for this challenge. There needs to be further research and findings which can provide more factors responsible. Major studies in this field in the near future can identify many other factors which are even date beyond our knowledge.
Characterization and Classification of Brain Tissue and Stroke Lesions in Non-Contrast Computed Tomography Images of Stroke Patients Using Statistical Texture Descriptors and Artificial Neural Network

Published: May 2022

Aim: To characterize and classify stroke lesions and normal brain tissue in computed tomography (CT) images using statistical texture descriptors.

Patients and methods: Two experienced radiologists blinded to each other inspected CT images of 164 stroke patients to identify and categorize stroke lesions into ischaemic and haemorrhagic subtypes. Four regions of interest (ROIs) in each CT slice that demonstrated the lesion; two each representing the lesion and normal tissue were selected. Statistical texture descriptors namely, co-occurrence matrix, run-length matrix, absolute gradient and histogram were calculated for them.  Raw data analysis was performed to identify the parameters that best discriminate between normal brain tissue and stroke lesions. Artificial neural network (ANN) was used to classify the ROIs into normal tissue, ischaemic and haemorrhagic lesions using the radiologists’ identification and categorization as the gold standard, and further analyzed using the receiver operating characteristic curve.

Results: Three parameters in each texture class discriminated between normal tissue, ischaemic and haemorrhagic stroke lesions. The discriminating co-occurrence matrix parameters were sum average parameters namely S1-1 SumAverg, S1-0 SumAverg and S0-1 SumAverg.  For the run-length matrix, short run emphasis in horizontal, 1350 and 450 directions were the discriminating features. The discriminating absolute gradient parameters were gradient non-zeros, gradient variance and gradient mean. For the histogram class, the mean, 90th and 99th percentiles were the discriminating parameters. The ANN achieved a sensitivity of 0.637, specificity 0.753, false positive rate (FPR) 0.247, and false negative rate (FNR) 0.363 with co-occurrence matrix. With run-length matrix the sensitivity was 0.544, specificity 0.607, FPR 0.393, and FNR 0.456 while with absolute gradient the sensitivity was 0.546, specificity 0.586, FPR 0.414, FNR 0.454. With histogram, the sensitivity was 0.947, specificity 0.962, FPR 0.038, and FNR 0.053.

Conclusion: The histogram texture features showed the highest sensitivity and specificity in the classification of brain tissue and stroke lesions using the artificial neural network.

Institutional capabilities that endow the individual and collective agency for institutional change (Revisiting Selznick)
Authors: Braga Ana Carolina Simões , Bataglia Walter
Published: May 2022

Organisational neoinstitutionalism is formed by a plethora of analytic approaches for understanding the institutions, presenting both macro and micro-sociological perspectives. In the former, the action is defined by the institutions and, in the latter, there is an emphasis on the social actors in institutional life. This study conducts a critical review of the literature of the old organisational institutionalism, focusing on the construct of institutional capabilities proposed by Selznick, and develops a comparative analysis between these capabilities and those of the organisational neoinstitutionalism, as well as approaches derived from it. From this analysis it is possible to synthesise an alternative for studying the institutional change, i.e., re-institutionalisation, based upon the institutional organisational capabilities.

Authors: Cassol Alessandra , Marietto Marcio Luiz , Martins Cibele Barsalini
Published: May 2022

A inovação está diretamente relacionada à criação e atualização do conhecimento e é vital para a sobrevivência das pequenas e medias empresas (PME). Este estudo examinou empiricamente a influência dos elementos que compõem as dimensões da capacidade absortiva (CA) na inovação das PMEs. A pesquisa realizou uma survey em 309 PMEs. A análise foi realizada por meio da técnica de modelagem de equações estruturais utilizando o Software Smart PLS. Os resultados mostraram que os elementos que compõem as dimensões de PACAP e RACAP tem um efeito positivo na inovação das PMEs, porém influenciam de forma diferente o processo de inovação das PMEs. O estudo contribuiu teoricamente para comprovar que o modelo de CA mantém a mesma configuração no universo de PMEs e contribuiu gerencialmente ao demonstrar aos gestores/proprietários que especial atenção deve ser disponibilizada à dimensão da RACAP nos processos de inovação nas PMEs.

Para tanto, foi aplicado um questionário, utilizado no trabalho original de Kahneman e Tversky (1979) e adaptado por Faveri et al. (2013), em 73 alunos do curso de graduação de Ciências Contábeis da Universidade Federal de Juiz de Fora. Tal questionário ocorreu em dois momentos, sendo o primeiro sem conhecimento e discussão sobre a teoria da utilidade esperada, e, em um segundo momento, após a explicação do conceito do valor esperado. Além da análise das questões frente aos efeitos certeza, reflexão e isolamento da TP, a originalidade do estudo consiste nas comparações dos resultados obtidos nessa pesquisa com os resultados apresentados no artigo de Faveri et al. (2013), que inspirou esse trabalho. Realizou-se, também, uma análise comparativa, em âmbito geral, dos resultados obtidos no momento subsequente (segunda aplicação) à presente pesquisa, com os resultados de outras pesquisas selecionadas, para que por fim, fosse realizada uma análise sob a ótica do gênero. Conforme evidenciam os resultados, a amostra deste trabalho possui indícios da presença dos mesmos vieses encontrados por Kahneman e Tversky (1979) e por outros estudos empíricos, fortalecendo as inferências de que aspectos comportamentais podem influenciar as escolhas dos indivíduos.
Update of treatment of heart failure with reduction of left ventricular ejection fraction
Authors: Aronow Wilbert
Published: May 2022

Underlying and precipitating causes of heart failure (HF) with reduced left ventricular ejection fraction (HFrEF) should be identified and treated when possible. Hypertension should be treated with diuretics, angiotensin-converting enzyme (ACE) inhibitors, and β-blockers. Diuretics are the first-line drugs in the treatment of patients with HFrEF and volume overload. Angiotensin-converting enzyme inhibitors and β-blockers (carvedilol, sustained-release metoprolol succinate, or bisoprolol) should be used in treatment of HFrEF. Use an angiotensin II receptor blocker (ARB) (candesartan or valsartan) if intolerant to ACE inhibitors because of cough or angioneurotic edema. Sacubitril/valsartan may be used instead of an ACE inhibitor or ARB in patients with chronic symptomatic HFrEF class II or III to further reduce morbidity and mortality. Add an aldosterone antagonist (spironolactone or eplerenone) in selected patients with class II–IV HF who can be carefully monitored for renal function and potassium concentration. (Serum creatinine should be ≤ 2.5 mg/dl in men and ≤ 2.0 mg/dl in women. Serum potassium should be < 5.0 mEq/l). Add isosorbide dinitrate plus hydralazine in patients self-described as African Americans with class II–IV HF being treated with diuretics, ACE inhibitors, and β-blockers. Ivabradine can be used in selected patients with HFrEF.

Introduction:  Inflammation plays a key role in atherosclerosis, and discovering new biomarkers of inflammation is becoming important in order to uncover the pathogenesis of atherosclerotic coronary artery disease (CAD). Recent studies have focused on polymorphonuclear neutrophils. It has been suggested that human neutrophil peptide 1-3 (HNP1-3) is proatherogenic. In this study, we aimed to investigate the associations between plasma HNP1-3 levels and the severity of atherosclerosis via a generally accepted scoring system.

Material and methods: This cross-sectional, observational study included 107 consecutive patients suffering from stable angina pectoris and undergoing coronary angiography (CAG). Patients were divided into two groups according to the Gensini scoring (GS) system evaluating disease severity. Group 1 was composed of mild CAD patients with GS < 20 and group 2 consisted of severe CAD patients with GS ≥ 20. Plasma HNP1-3 levels were assessed by the ELISA method.

Results: The mean HNP1-3 levels were found to be lower in group 1 than group 2 (134.7 ng/ml vs. 147.5 ng/ml). HNP1-3 levels were significantly higher in the severe CAD group than the mild CAD group according to GS (p < 0.001). The results of multivariate logistic regression analysis revealed that only age > 62 years and HNP1-3 > 134 ng/ml were independent predictors of the severity of CAD after adjusting for gender, smoking, hypertension, hyperlipidemia, diabetes, family history of CAD and white blood cell count. In predicting the severity of CAD, the sensitivity and specificity of HNP1-3 were 83.9% (p < 0.001) and 58.8% (p < 0.001), respectively.

Conclusions: This study revealed that the plasma levels of HNP1-3 were significantly higher in severe CAD than mild CAD.

Introduction: Primary percutaneous coronary intervention (PPCI) is the preferred treatment of ST segment elevation myocardial infarction (STEMI). Manual thrombectomy catheters developed to prevent distant embolization are theoretically attractive; however, their clinical efficacy remains controversial. The effects of manual thrombectomy catheters on angiographically visible distal embolisation (AVDE) have not been studied so far. The aim of this study was to evaluate the effects of manual thrombectomy during PPCI on AVDE and to investigate whether there are differences in the incidence of AVDE according to the catheters used.

Material and methods: Six hundred thirty-six consecutive patients undergoing primary PCI were included in the study between January 2010 and December 2012. Patients were divided into two groups: the PCI only group (465 patients) and the PCI plus manual thrombectomy group (171 patients).

Results: Thrombus aspiration was associated with higher AVDE (13.55% vs. 26.9%, p = 0.0001), lower thrombolysis in myocardial infarction frame rate (2.49 ±0.86 vs. 2.79 ±0.57, p = 0.0001), lower myocardial blush grade (2.31 ±0.87 vs. 2.47 ±0.7, p = 0.016), lower ejection fraction (EF) (49.9 ±8.5 vs. 46.1 ±9.6, p = 0.0001) and higher maximal troponin release (15.7 ±16 vs. 9.4 ±11, p = 0.0001). No difference was observed in terms of mortality between the groups in follow-up (5.2% vs. 9.03%, p = 0.12). Angiographically visible distal embolisation was observed more frequently with Invatec catheters (p = 0.0001).

Conclusions: Angiographically visible distal embolisation during primary PCI occurs in a significant number of patients treated with manual thrombectomy. The results indicated that the incidence of AVDE may be different depending on the thrombectomy catheters used.

The association between myofascial trigger points of the quadriceps femoris muscle and the clinical presentation of patellofemoral pain syndrome using a piloted patellofemoral pain severity scale
Authors:   , Dippenaar Donna Lisa
Published: May 2022

The purpose of this study was to investigate the role of Myofascial Trigger Points of the quadriceps femoris muscle in the clinical presentation of Patellofemoral Pain syndrome. Patellofemoral Pain Syndrome according to current literature suggests an extensor mechanism dysfunction as the most probable etiology, however this syndrome has posed many unsolved mysteries and challenges to the medical community and remains a difficult condition to treat. Myofascial pain syndrome in contrast to this is a regional muscular disorder that results from myofascial trigger points within the muscle. The presence of these trigger points could result in anterior knee pain, imbalance of the extensor mechanism and instability of the patellofemoral joint, which could present as a Patellofemoral Pain Syndrome.
Guidelines to enhance patient centred care for mental health care users in community psychiatric clinics in uMgungundlovu District, KwaZulu-Natal

The implementation of the Mental Health Policy Framework and Strategic Plan 2013-2020 promotes the integration of mental health into the general health care stream, intending to reduce the stigma and discrimination associated with mental health disorders. The policy on the integration of services suggests a more holistic and patient-centred approach to nursing mental health care users (MHCUs) in community psychiatric clinics. A substantial amount of research has been done on the integration of services and patient-centred care (PCC) in South Africa. No studies have been found that were conducted specifically with professional nurses and the provision of guidelines on enhancing PCC for MHCUs in the community psychiatric settings taking into consideration the integration of services. Aim The aim of the study was to identify the extent to which mental health has been integrated into the general health stream and ultimately develop guidelines to enhance patient - centred care for MHCUs in community psychiatric clinics in the uMgungundlovu District, KwaZulu Natal (KZN). Methodology A convergent parallel mixed-methods approach was used in the current study. The professional nurses and operational managers who met the inclusion criteria were purposely included in the sample. Data collection was achieved through three phases, namely; by observation using an observation checklist, surveys in the form of individually structured questionnaires and one -on - one interviews guided by a list of pre-set questions. Data from phases one and two were analysed using the Statistical Package for Social Sciences (SPSS) Software Version 25. Descriptive statistics were used to summarise and describe the analysed data and the findings were also presented in the form of tables and graphs. Inferential statistics were applied to identify significant trends. Data from the one-on-one interviews were coded and analysed until relevant themes and sub-themes were realised. Findings Professional nurses reported that the integration of services was in line with the prescripts of the ideal clinic. The policy on the integration of services was implemented although professional nurses expressed that it was not effective due to MHCUs temperament. Professional nurses that were in direct contact with MHCUs daily tried to give off their best to MHCUs and practice PCC. They reported that open communication, teamwork, appropriate nurse-patient relationships, adequate and updated in-service on PCC were essential components in the delivery of PCC. However professional nurses also faced barriers that prevented the successful implementation of PCC; namely: staff shortages, time constraints, and large numbers of patients, impatient patients and inexperienced nurses. The findings of all three phases were triangulated with the integration of the Neuman’s Systems model which guided this study to assist in the development of the proposed guidelines to enhance PCC.

Water pollutants are a major problem for the world. Especially, heavy metals are significant environmental pollutants due to their tendency on accumulation in organisms and causing toxic effects on humans, animals, and aquatic organisms. Therefore, qualitative and quantitative analyses of pollutants are important. Especially the analysis of contaminants in tap water is important. In this study, unlike previous studies, physicochemical water quality parameters were also studied for the first time along with heavy metal analysis. Water-quality parameters (pH, temperature, conductivity, and dissolved oxygen) were determined in tap-water by YSI 556 MPS, other parameters such as biochemical oxygen demand (BOD) and chemical oxygen demand (COD) were determined by electrometric and titrimetric methods. Various anions were analysed with the UV-VIS spectroscopy technique. Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn were analysed as pollutants by ICP-OES. Amount of Cr, Cd, Ni, and Pb were found as detectable limits, but Cu, Fe, Mn, and Zn were found 0.003 ppm, 0.173 ppm, 0.009 ppm, and 2.343 ppm, respectively. The pH of the tap water was in the interval 6.64 and 7.12 (mean: 6.85 ± 0.12). Nitrite varied between 0.20 and 0.60 mg/L (average: 0.36±0.001 mg/L) revealing that the tap waters exceeded the TSE standards for first quality drinking waters (0.20 mg/L). The data were evaluated using the relevant statistical analyses
