Published: February 2022

Anemia merupakan suatu keadaan dimana sel darah merah atau konsentrasi hemoglobin berkurang sehingga jumlah pengangkutan oksigen tidak cukup atau sel darah merah yang abnormal. Anemia pada kehamilan adalah anemia yang ditandai dengan kadar hemoglobin kurang dari 11 gr/dl pada trimester kedua. Klasifikasi anemia yaitu, anemia ringan dengan kadar hemoglobin (8-9,9 g/dl), anemia sedang (6-7,9 g/dl), anemia berat hemoglobin (< 6,0 g/dL). Deteksi dini merupakan langkah awal untuk pencegahan, dapat dilakukan dengan cara pemeriksaan kadar hemoglobin selama kehamilan.Jenis penelitian adalah deskriptif yang dilakukan di Klinik Helen Tarigan. Populasi semua ibu hamil yang berkunjung di Klinik Helen Tarigan, sampel berjumlah 20 responden. Teknik pengambilan sampel adalah total sampling. Pengumpulan data menggunakan data primer dengan kuesioner. Analisa data dengan menggunakan analisa univariat untuk distribusi frekuensi.Dari hasil penelitian pada pengetahuan tanda dan gejala tentang deteksi dini menunjukkan sebagian besar responden di Klinik Helen Tarigan berpengetahuan cukup (50%), bila dilihat dari usia menunjukkan sebagian besar ibu hamil dalam usia produktif usia 20-35 tahun (90%), pendidikan mayoritas SMA (70%), pekerjaan mayoritas tidak bekerja (75%), paritas mayoritas multigravida (55%) dan kadar hemoglobin paling banyak ibu yang mengalami anemia ringan (45%). Dari penelitian ini, peneliti menyimpulkan bahwa pengetahuan tanda dan gejala tentang deteksi dini anemia di klinik Helen Tarigan adalah kategori cukup sebanyak 10 responden (50%), dan kadar hemoglobin pada ibu hamil yang mengalami anemia ringan sebanyak 9 responden (45%), Hal ini dikarenakan kurangnya pengetahuan serta infomasi yang didapatkan ibu hamil tentang deteksi dini anemia.

Dr. Lourdes A. Manahan Batch 1943 of the University of the Philippines College of Medicine laid the groundwork for the subspecialty of Rheumatology in the Philippines in the 1960s. She established the Section of Rheumatology in 1971, now known as the Division of Rheumatology of the Department of Medicine of the University of the Philippines Manila - Philippine General Hospital.

During those early years, as the only rheumatologist in the country, she multitasked as clinician, teacher, researcher and mentor. She represented the country in various international forums, putting the Philippines and the University of the Philippines in the international Rheumatology community.

In 1981, a formal two-year fellowship program in rheumatology at PGH was established, the first of its kind in the Philippines. From there, the Section of Rheumatology grew by one trainee every 3-5years, By the late 1980, the section had graduated five rheumatologists, all of whom stayed in the country to render service. On its 50th year, the Division which was started by two rheumatologists has produced more than 80 astute specialists to serve patients with rheumatic diseases throughout the country. Its continuing patient advocacy has led to various programs and publications targeted to improve the lives of patients. Its contribution in the field of research has been recognized in local and international venues. It is recognized as, and will continue to be, a significant contributor to the growth of Rheumatology in the Philippines in decades to come.

We hope to honor the legacy of Dr. Lourdes Manahan through this special issue. The Division is eternally grateful for the passion for teaching, service, and research of Professor Clemente Amante and Professor Ester Gonzales-Penserga who continue Dr. Manahan’s work. To my colleagues in the Division, Professor Bernadette Heizel Manapat-Reyes, Professor Michael Tee, Associate Professor Jose Paulo Lorenzo, Associate Professor Eric Jason Amante, Associate Professor Angeline-Therese Santiago, and Associate Professor Geraldine Zamora, the challenge to keep the fire burning lies with us. To all who train and trained in the Division and contribute to the research we share, congratulations!

Jumping the Gap: developing an innovative product from a Social Network Analysis perspective
Authors: Martín Ferron Leandro
Published: February 2022

The creation of new products from the bonding between science and industry incorporates aspects that can be reviewed based on the nature of the academy-business bonds, the structure of the science & technology systems, or the models of academy-industry articulation. This research proposes a novel approach based on the analysis of a case study and uses the perspective of social network analysis to reconstruct the academic-state-business links necessary for the generation of innovation. The main source of data was the narration of a key informant, taking the innovative product as the ego of the network. Knowledge circulation pathways were identified, as well as subgroups of nodes whose attributes are associated with the product's transfer, development, and financing actions. The actor with the highest degree of centrality in the network belongs to the academic sector, and he operated as a bridge that bonded the academic and state sectors. This could be an indication that the promotion of this type of profile within the academic sector could boost the development of innovative products based on scientific knowledge.

Obesity became recognized in the classification of diseases 79 years ago (1948-2017). Since then, it has risen exponentially to become a global treat to health affecting different populations. The estimation of obesity prevalence cannot be overstressed. Therefore, this study investigated the prevalence of overweight and obesity among secondary school students in Ilorin Metropolis, Nigeria. A cross-sectional design was adopted for this study; the population for this study comprised all the secondary school students in the metropolis. Multistage sampling method comprising stratified; proportionate and simple random was used to select 1,569 participants for this study. Four research questions and hypotheses were answered and tested for this study. Frequency counts and percentage was used to answer the questions and independent sample t-test was used to test the hypotheses at 0.05 significance level. Anthropometric measures of Body Mass Index. (BMI) and Waist-Hip Ratio (WHR) conducted for classifications into overweight and obesity using percentile ranking. The standardized instruments for data collection were weight scale (BF9015B model) and inelastic tape rule that provides 100g tension. All the measurements for this study were ISAK compliant. The four hypotheses were rejected and the percentage analysis of the data indicated that; 28.1% of the male students in the private schools were obese, 20.1% were obese in the public schools. In the female category, 23.0% were obese in the private schools while 21.8% were obese in the Public schools. The mean WHR for female in the private and public schools were 0.87 and 0.80 respectively. It was concluded that; overweight and obesity was prevalent in the schools but higher prevalent was recorded in the private schools. Regular participation in physical activity and routine assessment of overweight and obesity status of the students using BMI and WHR methods for monitoring and timely interventions were part of the recommendations.

Published: February 2022

The proportion of individuals with depression has rapidly increased along with the growth of the global population. Depression has been the currently most prevalent mental health disorder. An effective depression recognition system is especially crucial for the early detection of potential depression risk. A depression-related dataset is also critical while evaluating the system for depression or potential depression risk detection. Due to the sensitive nature of clinical data, the availability and scale of such datasets are scarce. Depression is classified as a mood disorder. It may be described as feelings of sadness, anger, or loss that interfere with a person’s everyday activities. People experience depression in different ways. In certain cases, depression may lead to fatal cases. To avoid all of these, depression must be detected at the earliest and victim must be treated with appropriate remedies. The objective of the project is to analyze the emotion of a user using real-time video. This is achieved using Convolutional Neural Networks [CNN]. The final decision result comes from the combination of the two models. Finally, we evaluate all proposed deep models on our built dataset. The experimental results demonstrate that (1) our proposed method can identify patients/users with potential depression risk; (2) the recognition performance of combined 2D and 3D features model outperforms using either 2D or 3D features model only; (3) the performance of depression recognition is higher in the positive and negative emotional stimulus. Meanwhile, we compare the performance with other methods on the same dataset.

Pectin is complex polysaccharides contains 1, 4-linked x and β galactosyluronic acid residues extracted using alcohol precipitation method from citrus peels. The color of pectin from orange peel was pale yellow. Pectin is soluble in hot and cold alkaline water. The pectin is polysaccharide use as a stabilizer in foods. The pectin was extracted from various citrus fruit peels and its optimization by varying pH using hydrochloric acid and citric acid. Pectin can be used to improve the mouth feel and the pulp stability in juice-based drinks and as a stabilizer in acidic protein beverages. Extraction of pectin from citrus fruit peels like Orange peels, sweet orange and lemon gives higher yield of pectin. % Yield and rate of extraction for pectin from orange and sweet lemon (Mosambi) peels depends on parameters such as pH, temperature, solvent, time of extraction. Extraction carried out at pH 1.5 at 60 min with 60,70 & 80 OC temperature. The higher yield of pectin at pH value 1.5 and contact time 60 min. The extraction of pectin such as Citric Acid, Hydrochloric Acid, Sulphuric Acid, Nitric Acid and oxalic acid (C2H2O4). The time of extraction increased to an extreme there is less effect on yield of pectin reported and also decreased from maximum level due to thermal degradation of the extracted pectin.

Interventions for Instrumental Activities of Daily Living Among Adults With Multiple Sclerosis: A Systematic Review
Authors: Cunningham Rebecca , Uyeshiro Simon Ashley
Published: February 2022

Importance: Occupational therapy practitioners need updated information about interventions that may improve or maintain functional changes in instrumental activity of daily living (IADL) engagement caused by multiple sclerosis (MS).

Objective: To conduct a narrative synthesis of updated evidence on interventions within the scope of occupational therapy to improve or maintain performance of and participation in IADLs among adults with MS.

Data Sources: CINAHL, MEDLINE in PubMed, Cochrane, OTseeker, and PsycINFO.

Study Selection and Data Collection: This systematic review followed the Cochrane Collaboration methodology and is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for conducting a systematic review. Inclusion criteria were Level 1 or 2 evidence, published in English, published from January 2011 to December 2018, intervention within the occupational therapy scope of practice, and at least one IADL outcome measure.

Findings: Nineteen randomized controlled trials (including pilot and feasibility trials) and 1 preintervention–postintervention study met inclusion criteria. Results of this review show strong strength of evidence for coaching interventions in addressing physical activity (PA) routines and moderate support in addressing medication routines. Moderate strength of evidence was found with mixed results for interventions involving coaching plus prescribed PA in improving PA participation.

Conclusions and Relevance: This systematic review supports occupational therapy practitioners addressing PA and medication health management and maintenance IADLs through the use of coaching interventions when treating people with MS. Other IADLs were addressed by the articles in this review but require more evidence to make clinical recommendations.

What This Article Adds: Occupational therapy practitioners’ skills in promoting habits and routines paired with utilization of evidence-supported coaching interventions can support independence with health management and reduce the negative impact of MS on daily activity participation.

The multi-object spectroscopy technique was implemented on the Russian-Turkish 1.5m optical telescope (aka. RTT150)by modifying the slit wheel of its main instrument TFOSC (TÜBİTAK Faint Object Spectrograp and Camera). Remotelycontrolled rotating holders of the multi object masks were installed in the two nests of the slit wheel. The accuracy ofthe mask unit’s rotation is the order of 1 arcminutes, in which the image plane for 2 sources located at a separation of5 arcminutes corresponds to a positional accuracy of 0.1 arcseconds. To investigate the quality of the MOS technique inRTT150, the well-known merging galaxy cluster Abell 1914 was observed spectroscopically. The dispersion of the diﬀerencesbetween known and RTT150 redshift estimations is 0.0006, which is good enough for cosmological studies.

Light-curve modelling in a Roche plus stellar wind model: the massive binary WR22
Authors: Antokhina E. , Antokhin I. , Lenoir-Craig G. , St-Louis N. , Moﬀat A.
Published: February 2022

A code for the synthesis of light curves of close binaries in the Roche model is proposed which incorporates a stellarwind around one of the stars. The code makes it possible to analyze observations of binary systems containing Wolf-Rayetstars. This paper presents the results of the application of this code to the spectroscopic binary WR22, whose componentsare stars of spectral types WN7h and O9III-V (P = 80.336 d , e ∼ 0.6). The light curves were obtained with one of theBRITE-Constellation space-based telescopes. Two solutions to the problem were found, corresponding to two possibleluminosity classes of the O star, O9III and O9V. For each solution, the orbital inclination, the masses of the components,the temperature of the WR star, the WR mass-loss rate, and other parameters were determined. The resulting stellarparameters favour the solution for the WN7h+O9V model

Published: February 2022

We consider the destruction of dust at high galactic altitudes based on an earlier developed model of the movement of dustin the Galaxy, due to the stellar radiation pressure, gravity and gas drag. The possibility of dust sweeping is consideredtaking into account its collisions with the Galactic gas and between dust particles. Also, we clarify the range of grain sizesthat can get into intergalactic space due to the described mechanism.
Migration of planetesimals to planets located in habitable zones in the Solar System and in the Proxima Centauri system
Authors: Ipatov S.I.
Published: February 2022

The values of the probability of a collision of a planetesimal with the Earth were typically greater for smaller distances Rfrom the Sun at 3 < R < 40 AU. The probability varied from about 10 −6 at R ∼ 30 − 40 AU to 10 −3 − 10 −2 at R about3.2-3.3 AU. Though only one of several hundreds of planetesimals from the zone of exoplanet c in the Proxima Centaurisystem reached the inner exoplanet b, it often collides with the planet b. The probability of a collision of such planetesimalwith the exoplanet b could be about several 10 −4 . A lot of icy material could be delivered to inner exoplanets b and d inthe Proxima Centauri system.

Published: February 2022

The origin of supermassive black holes (SMBH) in galaxy centers still remains uncertain. There are two possible ways oftheir formation — from massive (10 5 − 10 6 M ⊙ ) and low-mass (100 M ⊙ ) BH nuclei. The latter scenario should leave behinda large number of intermediate mass black holes (IMBH, 10 2 − 10 5 M ⊙ ). The largest published sample of bona-ﬁde IMBH-powered AGN contains 10 objects conﬁrmed in X-ray. Here we present a new sample of 15 bona-ﬁde IMBHs, obtainedby conﬁrming the optically selected IMBH candidates by the presence of radiation from the galactic nucleus in the X-rayrange, which increases the number of conﬁrmed IMBHs at the centers of galaxies by 2.5 times. In the same way, 99 blackholes with masses of 2 · 10 5 − 10 6 M ⊙ were conﬁrmed. The sources of X-ray data were publicly available catalogs, archivesof data, and our own observations on XMM-Newton, Chandra and Swift. The Eddington coeﬃcients for 30% of the objectsfrom both samples turned out to be close to critical, from 0.5 to 1, which is an unusually high fraction. Also for the ﬁrsttime for light-weight SMBH the correlations between the luminosity in the [OIII] emission line or the broad component ofthe Hα line and the luminosity in the X-ray range were plotted.

Giant low surface brightness galaxies (gLSBGs) with the disk radii of up to 130 kpc represent a challenge for currentlyaccepted theories of galaxy formation and evolution, because it is diﬃcult to build-up such large dynamically cold systemsvia mergers preserving extended disks. We summarize the in-depth study of the sample of 7 gLSBGs based on the resultsof the performed spectral long-slit observations at BTA SAO RAS, surface photometry and Hi data available in literature.Our study revealed that most gLSBGs do not deviate from the Tully-Fisher relation. We discovered compact elliptical (cE)satellites in 2 out of these 7 galaxies. Provided the low statistical frequencies of gLSBGs and cEs, the chance alignment isimprobable, so it can indicate that gLSBGs and cE are evolutionary connected and gives evidence in favor of the majormerger formation scenario. Other formation paths of gLSBGs are also discussed.

The correlation of optical and γ-ray emission of the blazar 3C 454.3 during the multi-wavelength ﬂare from 2012 to 2017 isanalyzed. The light curves have a complex structure, especially during the period of maximum radiation in 2014, when theactivity in the form of a series of 4-5 small ﬂares is observed. The cross-correlation functions exhibit almost zero lag betweenBVR and γ-ray emission at diﬀerent periods of the long-term ﬂares. This suggests that optical and γ-ray emission come fromapproximately the same location (probably the base of the jet) and are physically connected. In general, optical emission lagsbehind gamma radiation except a few cases. It is assumed that both synchrotron radiation and inverse Compton scatteringby relativistic electrons and protons, which is typical for strong ﬂares, are present. The rotation of γ-ray radiation regionrelative to optical one is supposed.

We present a study of the distribution of dust in the nearby edge-on galaxy NGC 4437 by modelling its surface brightnessdistribution based on the Herschel data at 250 µm. Our model utilizes a 3D exponential disk function with two exponentialscales and a break radius which is suitable to describe the observed galaxy proﬁle in great detail. The model is improved bymasking background and foreground galaxies and by analysing the brightness distribution of separate bright sources insidethe galaxy. As a result, we found that this galaxy has a second dust disc. We also discuss the possibility of detecting asecond dust disc component in other edge-on galaxies.

We ﬁt theoretical isochrones from diﬀerent models of internal structure and evolution of stars to photometric data for thestars in globular clusters of our Galaxy. To select cluster members, determine cluster sizes and calculate systemic propermotions, we use parallaxes and proper motions from Gaia EDR3. To calculate the most probable distance, age, interstellarextinction in a variety of ﬁlters and diﬀerential reddening in cluster ﬁelds, we use photometry in more than 26 ﬁlters betweenthe ultraviolet and mid-infrared waverange from HST, Gaia EDR3, Pan-STARRS DR1, DES, SDSS, unWISE, SAGE andother datasets in combination with the PARSEC, MIST, DSEP, and BaSTI-IAC isochrones, as for the solar metallicityscale as for alpha- and helium-enriched scales. The metallicity and enrichment of the clusters is taken from spectroscopicobservations and tested for compliance with the photometric results. We carry out a thorough analysis of random andsystematic uncertainties of the obtained results. The derived extinctions in many ﬁlters allow us to estimate an empiricalextinction law for each cluster. A complete analysis has been performed for ﬁve clusters (NGC288, NGC362, NGC5904,NGC6205, and NGC6218), a preliminary analysis, based on the Gaia EDR3 astrometry and photometry only, has beendone for 38 more clusters. The main conclusions are as follows. First, unprecedentedly accurate astrometry of Gaia EDR3allows us to segregate the cluster members from fore- and background stars and to indicate that the size of many clustersis much larger than previously thought. Second, the distances, derived by us from the photometry-to-isochrone ﬁtting, arestill more precise than distances from the Gaia EDR3 parallaxes. Third, contrary to the popular 2D reddening maps ofSchlegel-1998 and Planck, we found no clusters at high Galactic latitudes with an extinction A V < 0.1. Fourth, for thehorizontal branch second parameter quartet NGC 288–NGC 362–NGC 5904–NGC 6218, the age is undoubtedly the secondparameter.

Introduction In South Africa homoeopathy is relatively unfamiliar, even though it has been in existence with formal qualification from 1989 at the Durban University of Technology, (formerly Durban Institute of Technology and Techikon Natal) as well as the University of Johannesburg formerly Wits Technikon). A large portion of the South African public is unclear with regards to homoeopathic understanding and homoeopathic medicine use. South African studies exploring the perception of homoeopathy have revealed that there is a degree of ignorance or misinterpretation of homeopathy. The objectives of this study were to expand the database of knowledge regarding the patients’ experiences of homoeopathy, by investigating their experiences of homoeopathic care rendered at a PHC facility in the eThekwini district, namely, the Redhill homoeopathic clinic. This study was guided by the following grand tour question: What are the experiences of patients of homoeopathic care rendered at a primary healthcare clinic in the eThekwini District? Aim of the study The aim of this study was to determine the experiences of patients receiving homoeopathic care rendered at a primary healthcare facility in the eThekwini district. Methodology A qualitative, explorative, descriptive and contextual design was employed. Qualitative research in this study was considered the most appropriate method to gain an in-depth understanding of the patients’ experiences of homoeopathic care. Convenience sampling was used to recruit a minimum of 10 potential research participants from patients receiving homoeopathic care at the Redhill homoeopathic clinic, but the sample size was only determined once data saturation was obtained. The study population were patients who were visiting the Redhill homoeopathic clinic for the second time or more and those who had utilized homoeopathic remedies. The data was collected and analysed using Tesch’s eight-step procedure. Results Results from this study showed that the study group had knowledge of homoeopathy and that there is growth in the knowledge of homoeopathy as compared to previous studies. The researcher observed that Indian participants had a better understanding of homoeopathy than African participants. Participants showed great confidence in homoeopathy and most of them revealed a high level of satisfaction with the homoeopathic treatment and were very happy with the service delivery. Results showed that there had been an improvement of the patients’ ailments since the commencement of homoeopathic treatment.
Implementation of the basic antenatal care approach : a tailored practice framework for eThekwini district, KwaZulu-Natal

Published: February 2022

Globally antenatal care is advocated as the cornerstone for reducing children’s deaths and improving maternal health. The World Health Organization designed and tested a Focussed Antenatal Care model for the developing countries to improve their quality of antenatal care services. South Africa has not successfully implemented this approach, referred to by South Africa as the Basic Antenatal Care approach. A convergent parallel mixed methods design was used to assess how the Basic Antenatal Care approach was implemented in the eThekwini district. Data were collected from 12 Primary Health Care clinics using observations, retrospective record reviews and semi-structured interviews conducted with pregnant women. The quantitative data was analysed using version 21.0 of the Statistical Package of Social Services and qualitative data was analysed using Tech’s method of data analysis. The Basic Antenatal Care approach was not being successfully implemented in the Primary Health Care clinics. Several aspects of planning, people, processes and performance were not done according to the Basic Antenatal Care Principles of Good Care and Guidelines. Although good communication was observed between the clinic staff members and the referral institutions, communication problems existed between the Primary Health Care clinics and the Emergency Medical Rescue Services and also with the pregnant women. Antenatal care and delivery plans and the midwives’ counter checking of maternity charts were not recorded. Some pregnant women had positive perceptions about the antenatal care services but others had negative perceptions. Recommendations pertaining to institutional management and practice, nursing education and research were made. A tailored practice framework and an implementation guide were developed based on setting and client-specific factors to facilitate the implementation of the Basic Antenatal Care approach. The framework highlights the importance of cooperation between management and administration, in-service education and skills development departments/units and the operational level. Effective implementation of the Basic Antenatal Care approach could help to reduce South Africa’s high maternal and neonatal mortality rates. Thus the tailored practice framework and implementation guide, developed as part of this study, could help to improve maternal and neonatal health-related outcomes in South Africa.
