Factors Influencing Utilization of Routine Health Information For Decision Making Among Health Workers: A Case Study of Health Facilities in Moyo District, Uganda
Authors: Aggrey ASEGA Pam Charles , Odongo Alfred Owino , Kerochi Atei
Published: December 2022

Health information is a powerful vehicle for enhancing community health
and it highlights both the problems and opportunities that exist for
development. In Uganda, there are cases where decisions have been made
without using health information in primary health care units. The
existing capacity inadequacy to efficiently utilize information to track
service use patterns over time to determine the impacts of policy and
service delivery improvements in Uganda is one of the key weaknesses.
With the support of the Ministry of Health, the government of Uganda is
implementing projects to build and enhance the nation’s web-based
national health information system (DHIS2), which collects data from all
health systems and allows for making decisions based on evidence on the
delivery of health services. The broad study objective was to establish
the factors influencing the utilization of routine health information
for decisions making among the health workers. The research design was
based on an analytical cross-sectional design. The target population for
this study was 260 health workers specifically targeting those involved
in the use of routine utilization of health information. Purposive
sampling was used to select the key informants and other respondents
were selected using simple and stratified random sampling. The
self-administered structured questionnaire and key informants’
interviews were used to collect data from respondents. The analysis of
the quantitative data was done using descriptive statistics consisting
of tables, bar graphs, pie charts, frequency, percentages, mean and
standard deviations. Logistic regression analysis was conducted for
establishing the association amongst the variables. The study
established that technical factors (χ2=801.069; p=0.001), organizational
factors (χ2=895.224; p=0.000), and behavioural factors (χ2=994.559;
p=0.000) had a significant influence on utilization of routine health
information for decision making. Talk of significant predictors of
utilization of routine health information for decision making, technical
factors (p = 0.013) had the greatest influence on utilization of routine
health information for decision making among health workers at health
facilities followed by organizational factors (p = 0.049). The study
recommends that management of health facilities in Moyo district to
create organizational culture through increased demand for and use of
routine health information for evidence-based decision making in all
aspects. The study further established areas of the routine health
information system that requires to be reinforced and backed up to
ensure the use of routine data in health facility to make decisions.

During the first 2934 sols of the Curiosity rover’s mission 33,468
passive visible/near-infrared reflectance spectra were taken of the
surface by the mast-mounted ChemCam instrument on a range of target
types. ChemCam spectra of bedrock targets from the Murray and Carolyn
Shoemaker formations on Mt. Sharp were investigated using principal
component analysis (PCA) and various spectral parameters including the
band depth at 535 nm and the slope between 840 nm and 750 nm. Four
endmember spectra were identified. Passive spectra were compared to
Laser Induced Breakdown Spectroscopy (LIBS) data to search for
correlations between spectral properties and elemental abundances. The
correlation coefficient between FeOT reported by LIBS and BD535 from
passive spectra was used to search for regions where iron may have been
added to the bedrock through oxidation of ferrous-bearing fluids, but no
correlations were found. Rocks in the Blunts Point-Sutton Island
transition that have unique spectral properties compared to surrounding
rocks, that is flat near-infrared (NIR) slopes and weak 535 nm
absorptions, are associated with higher Mn and Mg in the LIBS spectra of
bedrock. Additionally, calcium-sulfate cements, previously identified by
Ca and S enrichments in the LIBS spectra of bedrock, were also shown to
be associated with spectral trends seen in Blunts Point. A shift towards
steeper near-infrared slope is seen in the Hutton interval, indicative
of changing depositional conditions or increased diagenesis.

Published: December 2022

  

Objective: To investigate whether serum uric acid (SUA) level was associated with all-cause and cardiovascular disease (CVD) mortality among individuals with diabetes. 

Research design and methods: In this prospective cohort, we included the patients with diabetes from the National Health and Nutritional Examination Survey (NHANES) 1999-2018. Mortality and underlying causes of death were ascertained by linkage to national death records through December 31, 2019. Weighted Cox proportional hazards regression models were used to evaluate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause and CVD mortality. We further performed a meta-analysis of available cohort studies to combine the association between SUA and mortality in diabetes.

Results: Among the 7,101 diabetes from NHANES 1999-2018, the weighted mean of SUA level was 5.7 mg/dL. During 57,926 person-years of follow-up, 1,900 deaths (674 deaths from CVD) occurred. In the fully adjusted model, when compared to patients with diabetes in the lowest SUA quintile, those in the highest SUA quintile had the HRs (95% CIs) of 1.28 (1.03, 1.58) for all-cause mortality and 1.41 (1.03, 1.94) for CVD mortality. We included 13 cohort studies in the meta-analysis, and found that the pooled HRs (95% CIs) were 1.08 (1.05, 1.11) for all-cause mortality and 1.05 (1.03, 1.06) for CVD mortality, with per 1 mg/dL increment of SUA level in diabetes. 

Conclusions: This study indicated that higher SUA levels were associated with increased risks of all-cause and CVD mortality in diabetes. Interventional studies are needed to elucidate the health effect of lowering uric acid treatments.

Authors: Miyata Kazuhiro , Tamura Shuntaro , Kobayashi Sota , Takeda Ren , Iwamoto Hiroki
Published: December 2022

Objectives: After confirming the measurement properties of the Berg Balance Scale (BBS) in patients with stroke by conducting a Rasch analysis, this study sought: (i) to generate a keyform as a tool for goal-setting and intervention-planning; and (ii) to determine the appropriate strata for separating patients’ postural balance ability. Design: Methodological analyses of cross-sectional study data.Patients: A pooled sample of 156 patients with stroke: mean (standard deviation) age 74.4 (12.9) years.Methods: This study evaluated the BBS’s rating scale structure, unidimensionality, and measurement accuracy (0: unable to perform or requiring help, to 4: normal performance) and then generated a keyform and strata.Results: The BBS rating scale fulfilled the category functioning criteria. Principal component analysis of standardized residuals confirmed the unidimensionality of the test. All items fit the Rasch analysis. Person ability-item difficulty matching was good. Person reliability was 0.96, and the patients were divided into 9 strata. The keyform for the BBS will enable clinicians and investigators to estimate patients’ postural balance ability and monitor their progress.Conclusion: The BBS has strong measurement properties. This study generated both a keyform that can contribute to clinicians’ decision-making in goalsetting and intervention-planning and strata that can facilitate understanding of patients’ abilities.
LAY ABSTRACTPeople who have had a stroke often have difficulty maintaining postural balance and controlling their posture. The Berg Balance Scale (BBS) measures a person’s ability to maintain postural balance. Several analyses were performed to investigate the measurement properties of the BBS in patients who have had a stroke. Then, a keyform tool was generated and some strata (levels) determined that separate patients according to postural balance ability. A keyform can help therapists to identify items that a patient finds relatively  difficult. Use of a keyform can contribute to both rehabilitation goal-setting and planned interventions for patients. The strata can be  used to detect and measure changes in a patient’s postural balance ability. The findings of this study demonstrate that the BBS has  strong measurement properties and provides an appropriate keyform and 9 strata. Use of these tools can facilitate the rehabilitation of patients with stroke through quantification of a patient’s postural balance ability.

Consideramos a importância de ambientes dialógicos que permitam o exercício de habilidades favorecedoras da autonomia, senso de responsabilidade e comunicação eficiente, capacidades relevantes para ressignificação de comportamentos considerados indisciplinados na escola.
Apoio psicológico ao universitário
Authors: Lomba Jonas Cardoso , Pan Miriam Aparecida Graciano de Souza
Published: December 2022

Este artigo apresenta uma proposta metodológica de apoio psicológico no Ensino Superior, desenvolvida por meio de rodas de conversa presenciais e oficinas realizadas em ambiente virtual, voltadas a estudantes que apresentam algum grau de sofrimento que possa culminar em questões de saúde mental e a subsequente evasão nesse nível da educação no Brasil. Tem por objetivo descrever os procedimentos metodológicos e avaliar seus resultados, considerando a adesão, o tipo de participação nas diferentes etapas propostas e a avaliação de uma das participantes, em entrevista individual, presencial. Constatou-se que a fase presencial da pesquisa representou uma dificuldade aos estudantes que tinham interesse na participação, mas não aderiram à proposta. Na fase virtual, fica evidenciado que escrever, para alguns estudantes, pode representar uma maneira possível para que sentimentos e pensamentos sejam expressos de modo intenso, também promovendo a troca entre participantes e o consequente ganho coletivo.

Etnomusikologisia näkökulmia musiikintutkimuksen dekolonisaatioon
Authors: Seye Elina
Published: December 2022

Suomessakin on alkanut keskustelu akateemisen maailman ja tieteellisen tiedon dekolonisaatiosta, jonka yhtenä keskeisenä lähtökohtana on tietämisen tapojen moninaisuus maailmassa ja tavoitteena akateemisen tiedekäsityksen laajentaminen niin, että se ei perustuisi vain eurosentriselle käsitykselle tiedosta. Hahmottelen aihetta käsittelevän tutkimuskirjallisuuden pohjalta, mitä dekolonisaatio voisi tarkoittaa nimenomaan musiikintutkimuksen kannalta ja millaisia muutoksia tiedon dekolonisaatio mahdollisesti vaatisi suomalaisen musiikintutkimuksen kentällä.
Väitän, että etnomusikologian tutkimusperinne voisi toimia lähtökohtana musiikintutkimuksen dekolonisaatiolle, sillä se on jo lähtökohdiltaan globaali, kaikkien maailman musiikkien tutkimisen tarpeellisuutta korostava tutkimusala. Vaikka etnomusikologian juuret juontavat kolonistista hallintoakin palvelleeseen antropologiseen tutkimukseen, alaa on jo vuosikymmenien ajan leimannut vahva eettinen ja itsekriittinen asenne tutkimuksen tekemisessä, samoin kuin etnografiselle kenttätyölle ominainen tapa tuottaa tietoa tiiviissä yhteistyössä niiden ihmisten kanssa, joiden musiikista on kyse. Juuri siksi etnomusikologit ovat jo vuosikymmenien ajan pohtineet monia niistä kysymyksistä, joista nyt puhutaan dekolonisaation otsikon alla.

Musiikki kotouttavana tekijänä: analyysi viiden nuoren musiikille antamista merkityksistä
Authors: Rytkönen Aino
Published: December 2022

Artikkelin aiheena on musiikin merkitys nuorten maahanmuuttajien kotouttamisessa suomalaiseen yhteiskuntaan. Aihe on tärkeä muun muassa musiikkikasvatuksen näkökulmasta, sillä kulttuurien moninaisuuden ymmärtäminen ja huomioiminen osana opetusta on entistä oleellisempaa. Tavoitteena on tutkia, millaisia merkityksiä musiikki luo Suomeen tulleille nuorille. Samalla selvitetään, mikä asema musiikilla on nuorten turvan tunteen muodostumisessa ja oman tulevaisuuden rakentamisessa uudessa kasvuympäristössä.
Kiinnostus aiheen tutkimiseen juontuu sen ajankohtaisuudesta. Vuonna 2015 maailma oli uuden äärellä, kun kymmenet tuhannet Lähi-idän pakolaiset hakivat turvaa Euroopasta. Kulttuuristen erojen ollessa suuria, laajempien kotouttamistoimien tarkastelu on tarpeen, minkä vuoksi laajempien kotoutumistoimien tarkastelu on tarpeen. Globalisoituneen maailman äärellä tarvitsemme yhä enemmän ymmärrystä eri kulttuureista ja onnistuneen integraation rakentumisesta.
Tutkimuksen aineisto koostuu viidelle Lähi-idästä tulleelle varhaisaikuiselle pidetystä teemahaastattelusta. Haastattelun kysymykset rakentuvat kolmen teeman varaan: haastateltavien henkilöhistoriaan, musiikin arvoon heille itselleen sekä sosiaalisen identiteetin rakentamiseen. Haastateltavista neljä on kotoisin alueilta, joissa musiikki koettiin ‘haramina’ eli kiellettynä.
Haastatteluaineistoa analysoitiin kokonaisuutena, ja sitä tulkittiin aiemman sosiologisen, kulttuurintutkimuksellisen ja musiikkikasvatuksellisen tutkimustiedon pohjalta. Keskeisin tulkinta tapahtui akkulturaatiomallin, psykososiaalisen kehitysteorian ja minätietoisuuden -mallin kautta.
Tutkimustulokset viittaavat siihen, että musiikilla on merkitystä nuorten maahanmuuttajien kotoutumisessa, joka parhaimmillaan johtaa integroitumiseen. Valtaosa haastateltavista esimerkiksi koki suomenkielisen musiikin tukeneen uuden kielen omaksumista nopeammin sekä auttaneen ymmärtämään suomalaista kulttuuria laajemmin.  Lisäksi laulettu musiikki oli helpottanut tutkimukseen osallistuneiden vaihtelevien tunteiden, kuten kotimaan kaipuun käsittelyä ja voimaannuttavien tunnetilojen tavoittelua. Tutkimustulosten pohjalta, voidaan nähdä, että musiikkia tulisi hyödyntää entistä johdonmukaisemmin nuorten integroitumisessa.

Hubungan Laju Infiltrasi Terhadap Peningkatan Aliran Permukaan di Daerah Pengembangan Permukiman Kota Padang
Authors: Sari Rani Widya , Andayono Totoh
Published: December 2022

Permasalahan yang terjadi pada lahan permukiman yaitu aliran permukaan (run off) akibat limpasan air hujan pada saat terjadinya curah hujan yang tinggi. Perubahan lahan akibat lahan permukiman diperkirakan akan berdampak pada perubahan arah limpasan yang akan mengarah ke permukiman. Pengujian ini bertujuan mengetahui berapa besar peningkatan nilai infiltrasi terhadap aliran permukaan di lahan permukiman kota Padang. Jenis penelitian kuantitatif dengan menggunakan pendekatan eksperimen dimana data terkait parameter infiltrasi seperti data laju infiltrasi, kapasitas infiltrasi, aliran permukaan dan intensitas hujan. Pengambilan data parameter infiltrasi dilakukan dengan menggunakan (double ring infiltrometer digital) dan data curah hujan untuk menunjukan hubungan laju infiltrasi terhadap aliran permukaan. Berdasarkan hasil penelitian yang telah dilakukan didaerah pengembangan permukiman kota Padang, maka diperoleh nilai infiltrasi dan aliran permukaan pada masing-masing lokasi. Pada saat curah hujan diperkirakan konstan, infiltrasi yang terbesar terjadi di awal hujan (f0) pada waktu ke 0,02 jam, sedangkan tanah mulai jenuh pada saat air keluar yaitu pada waktu jam ke 0.20. Tanah mulai jenuh total pada saat berpotongan pada jam ke 0,40 dengan intensitas hujan sebesar 128,24cm3/jam. Dimana semakin besar laju infiltrasi maka semakin kecil aliran permukaan (run off) begitu juga sebaliknya. Artinya semakin besar laju infiltrasinya maka semakin kecil terjadi banjir ataupun terjadinya genangan.
