Além da terapia medicamentosa, muitos pacientes utilizam plantas medicinais para o tratamento da hipertensão e do diabetes, muitas vezes sem o conhecimento sobre a eficácia e a segurança delas. Esta pesquisa investigou a prevalência dessa prática por diabéticos e hipertensos e analisou sua associação com variáveis sociodemográficas. Foi realizado um estudo epidemiológico, descritivo e transversal com 300 pacientes atendidos pela Unidade Básica de Saúde (UBS) Ouro Branco, em Umuarama-PR, que responderam a um questionário sociodemográfico e sobre o uso de plantas medicinais. A maioria dos participantes eram mulheres, com baixa escolarização e renda mensal. Em relação ao uso dessas plantas, foram citadas 27 espécies, mas apenas 7,7% dos respondentes as utilizavam de maneira preconizada. Concluiu-se que pacientes hipertensos e diabéticos recorrem a plantas medicinais sem o conhecimento da forma correta de preparo e da potencialidade dessas espécies em causar efeitos adversos.

Published: June 2021

O objetivo deste estudo foi avaliar o efeito do uso do Mapa da Empatia em Saúde (MES) na empatia médica percebida pelo paciente durante atendimento ambulatorial. Trata-se de um estudo experimental, em três fases, realizado com 22 médicos residentes de ortopedia. Na primeira fase, avaliou-se a empatia do médico na percepção dos pacientes atendidos no ambulatório de ortopedia, através do instrumento Consultation and Relational Empathy (CARE). Na segunda fase, após um treinamento, foi implantado o uso do MES pelo médico residente no atendimento ambulatorial por quatro semanas. Uma semana após a interrupção do uso do MES (3ª fase), foi novamente aplicada a escala CARE nos pacientes. Os resultados demonstraram aumento da percepção da empatia médica percebida pelos pacientes após a intervenção, sugerindo que o MES favoreceu o desenvolvimento do comportamento empático e, portanto, pode ser considerado como estratégia auxiliar para o desenvolvimento da empatia.

O objetivo deste estudo foi identificar a incidência da COVID-19 segundo positividade dos testes rápidos e os fatores associados na população do estado do Pará. Trata-se de um estudo transversal, analítico, retrospectivo, desenvolvido com os casos da COVID-19 em indivíduos notificados e residentes no estado do Pará. As informações foram coletadas no Portal de Transparência do Estado. Considerou-se a positividade para os testes rápidos da doença como variável desfecho. Análise de regressão logística foi utilizada para identificar associação entre as variáveis. A incidência da COVID-19 foi de 46% (IC 95%: 45,7-46,2). Ser do sexo masculino, ter idade acima de 80 anos e tempo de 22 dias ou mais para realização dos testes após o início dos sintomas aumentaram as chances para o resultado positivo. Conclui-se que existe a alta incidência da COVID-19 no estado. As estratégias de medidas não farmacológicas e de rastreamento de casos são importantes alternativas para mitigar a pandemia.

Published: June 2021

This paper presents the long-term experience of using reflex gymnastics according to the Vojta method in several medical centers in Russia, which is an important aspect of this method of therapeutic exercises, since no study has provided enough information about such experience. Combining the results of studies from Moscow and Russian cities made it possible to demonstrate the advantages of a highly effective method of treating a serious disease such as cerebral palsy. The variability and variety of technical approaches of the Vojta method depend on the severity and orthopedic manifestations of various diseases, which is an undoubted advantage of the technique. Vojta therapy not only works with human motor activity but has a pronounced and varied effect on numerous actions that are of higher nervous activity. Based on the presented experience of working with patients of different ages diagnosed with cerebral palsy, we can confidently recommend the need to use Vojta therapy in the complex treatment of the disease.

An acoustic medical diagnostic device was used to develop a prognostic criterion for assessing scar formation in these patients, and factors influencing the scarring process have been determined. Results of this study demonstrated that it is possible to determine the type of scarring at the early stage of wound healing in patients with purulent inflammatory diseases in the face and neck area using an acoustic medical diagnostic device that allows the assessment of the scarring type, prescribing adequate treatment, and taking preventive measures against pathological scarring of tissues.
On the frequency distribution of earthquake magnitude and intensity
Authors: Makjanić Berislav
Published: June 2021

abstract

Since the usual Gutenberg and Richter distribution of magnitudes does not give good fit to the observed data except in the middle of the range, it is proposed to find a new distribution of magnitudes starting from the two principles: (a) distribution of all magnitudes (initial distribution) has to be limited; and (b) distribution of the largest values (extremal distribution) has to be asymptotic extremal distribution for the given initial distribution. Since it is well established that the largest values of intensity and magnitude follow the so-called third asymptote, which is conveniently written in Jenkinson's form, the initial distribution which belongs to this extremal distribution is determined. A procedure for determining the parameters of the initial distribution is proposed. For the time being, better results are obtained from macroseismic intensities, since often the magnitudes are being determined from these intensities by means of the linear regression. As an example, the frequency distribution of the 100-yr series of intensity of Zagreb earthquakes is analyzed. It seems that this initial distribution, which turns out to be the generalized exponential distribution, gives good fit to the data.
Source inversion of seismic waveforms: The Koyna, India, earthquakes of 13 September 1967
Authors: Langston Charles A.
Published: June 2021

abstract

The treatment of the seismic source inverse problem, when diverse forms of waveform data are available, is simple and elegant using a moment tensor formalism. If earth structure is known and its effects predictable in terms of vertically inhomogeneous elastic-layered models, then all types of wave phenomena (e.g., surface waves, body waves, leaky modes, etc.) for a purely deviatoric moment tensor point source may be represented by, at most, a sum of three Green's functions. For an arbitrary symmetric moment tensor point source, one additional Green's function is needed for the P-SV system. However elegant this formalism may be for posing the linear inverse problem, the major difficulties lie in earth structure unknowns and resultant nonlinearities in the Green's functions which can cause significant trade-offs with source parameters. A hybrid inversion procedure is set up to gain insight into the probable unknowns in particular problems by incorporating both a linearized least-squares gradient method for the moment tensor or double couple, and smoothed time function parameters, and a nonlinear systematic trial-and-error search for moment tensor or double couple parameters for several assumptions of Green's function. The inversion technique is applied to near-regional waveform data from a small earthquake associated with the Koyna Reservoir which occurred 13 September 1967, as the second in a group of three events with very similar waveshapes, but differing amplitudes. The magnitudes of the second and third events are smaller by −0.2 and −0.8 units, respectively, compared to the first. The absolute magnitude for the first event is poorly constrained but is estimated to be 4.0 to 4.5 rather than the previously published value of 5.5 to 6.0. From the similarity of waveshapes, all three events are inferred to have the same mechanism and occurred within about 2 km of the same hypocenter. The results from moment tensor and double couple inversions for event 2 data indicate that source depth was 5 km and that left-lateral faulting occurred on a plane with a strike of N20°E ± 5°, dip of 90° ± 15°, and a rake of 0° ± 35°. The inferred far-field time function is approximately 3 sec in duration, unusually long for the seismic moment of 9 × 1022 dyne-cm, yielding a possible stress drop of about 0.05 bars. A fault map was constructed from LANDSAT image interpretation and shows a predominance of NNW to NNE striking faults in the Koyna area which is used to infer the appropriate nodal plane in the inversion results. These faults tend to define a broad en-echelon zone which parallels the Western Ghats in this area.
Seismic source functions and attenuation from local and teleseismic observations of the NTS events jorum and handley
Authors: Helmberger Donald V. , Hadley David M.
Published: June 2021

abstract

Several strong-motion seismograms recorded at 8 km from a large nuclear test at Pahute Mesa, Nevada Test Site, are modeled using the Cagniard-de Hoop technique. The ratio of vertical to radial motions suggest that the peak values are produced by ray paths that penetrated to a depth several kilometers below the source. A homogeneous layered Earth model with velocity increasing with depth was used in the modeling of the velocity time histories. The upper portion of the velocity model was determined by averaging bore-hole data and the lower portion was obtained from regional refraction measurements. Assuming a modified Haskell (1967) source representation,

ψ ( t ) = ψ o [ 1 − e − K t ( 1 + K t + ( K t ) 2 / 2 − B ( K t ) 3 ) ]

we obtain a range of source descriptions with ψ0 varying with K and B, ψ0 (K,B). The range of source models for Jorum are ψ0 (5, 1) = 3.1, ψ0 (5, 2) = 1.7, and ψ0 (5, 3) = 1.2 times 1011 cm3, respectively. Given an explosion source description, it is a straightforward task to determine the teleseismic attenuation from WWSSN observations. From both the short- and long-period observations from these events, an average t* of 1.3 is obtained for compressional waves of a dominant 1-sec period. This estimate is insensitive to the range of K and B obtained from the near-field modeling.
An investigation of discriminants for events in Western USSR based on regional phases recorded at station Kabul
Authors: Gupta Indra N. , Burnetti J. A.
Published: June 2021

abstract

Short-period, vertical-component records at the WWSSN station, Kabul for 13 earthquakes and 8 nuclear explosions occurring within a region of efficient propagation of Lg are examined to explore the possibility of using ratios of amplitudes in different group velocity windows as a discriminant. Each seismogram is divided into 10 windows with boundaries representing Pn and group velocities of 6.0, 5.0, 4.5, 4.0, 3.8, 3.6, 3.4, 3.2, 3.0, and 2.8 km/sec. The first three windows include crustal phases Pn, Pg, and Sn, respectively, whereas the six windows from 4.0 to 2.8 km/sec encompass the expected group velocity of higher mode Rayleigh waves that include Lg. The ratio of the maximum amplitude before the arrival of Sn to the maximum amplitude thereafter is significantly larger for explosions than for earthquakes and provides the largest separation between earthquake and explosion populations. Considerable separation is also shown by amplitude ratios Pn/Lg and Pn/Pg. Amplitude ratios based on earlier- and later-arriving Lg phases and the amplitude ratio Sn/Lg show insignificant discrimination. The ratio (maximum before Sn)/(maximum after Sn) is expected to be a useful regional discriminant for events in the Western USSR.
Seismic gaps and recurrence periods of large earthquakes along the Mexican subduction zone: A reexamination
Authors: Singh S. K. , Astiz L. , Havskov J.
Published: June 2021

abstract

Seismic gaps and recurrence periods of large, shallow interplate earthquakes along the Mexican subduction zone are reexamined after combining information from a catalog of nineteenth century's earthquakes, some relocated epicenters of the early part of this century, source parameters of recent large earthquakes, and redetermined magnitudes of great, shallow earthquakes of this century. Tehuantepec and Michoacan gaps have not experienced a large shock in this century and perhaps none in the past century; they are either aseismic or have anomalously large repeat times. Guerrero, Jalisco, and Ometepec regions presently appear to have a high seismic potential. Observed average repeat times of large earthquakes (Ms ≳ 7.4) in six regions (east, central, and west Oaxaca, San Marcos, Petatlan, and Colima) are between 32 to 56 yr. Data of this century indicate that the strain is released mostly in large events (Ms ≳ 7.4). A simple dislocation model with parameters obtained from the studies of recent earthquakes explains the observed recurrence periods quite well. The b value for this zone is not meaningful, an observation which is of significance for seismic risk estimation. Most of seismic moment (or, equivalently, seismic energy) release since 1800 appears to occur for 15 yr followed by relative quiescence in the next 15 yr.
Study of the Montenegro earthquake sequence (March-July 1979)
Authors: Console R. , Favali P.
Published: June 2021

abstract

Data from more than 80 European seismic stations, concerning foreshocks, the main shock, and aftershocks of the earthquake which occurred near the coast of Montenegro on 15 April 1979, have been collected and analyzed. The data have allowed the focal mechanism of the two strongest shocks to be estimated. The hypocentral coordinates of more than 180 aftershocks and some foreshocks have been also computed, giving the time-space distribution of the sequence. The shocks are mostly contained in an area about 100 km long and 30 km wide, almost corresponding to the Adriatic coast line of the Yugoslavia-Albania border region. The hypocentral depths, although determined approximately, appear to be in the order of 15 to 20 km. The results have been compared with previous knowledge of the tectonics of the zone.
Observation and inversion of surface wave group velocities across central India
Authors: Bhattacharya S. N.
Published: June 2021

abstract

Surface wave group velocities across central India are measured from computer plots of frequency-time analysis using multiple-filter technique. Periods range from 5 to 56 sec for fundamental mode Rayleigh wave, 5 to 16 sec for first higher mode Rayleigh wave, and 5 to 49 sec for fundamental mode Love wave. The wave paths from Koyna earthquakes to Bokaro cross purely through the Peninsular Plateau. The group velocities for these paths are found to be similar to those of surface waves recorded at Poona from earthquake which lie to the northeast of Bokaro in sub-Himalayan regions. From this, it is concluded that the shield structure of the peninsula extends to the sub-Himalayan regions to northeast of the Peninsular Plateu with a negligible part of sedimentary layer. Group velocities of fundamental mode Rayleigh and Love waves are also obtained for the paths from Koyna earthquakes to Shillong and are found to be similar to the above-mentioned group velocities except at very low periods where group velocities are affected by the small part of each path through thick sedimentary layer of Bengal Basin. Northern limit of this basin sedimentary layer has been identified.

Mean and standard deviation of observed group velocity at each period are obtained for each of Rayleigh fundamental, Rayleigh first higher, and Love fundamental modes. The group velocities closely agree with those obtained earlier for the path between New Delhi and Kodaikanal and are also found to be similar to those observed in some shield regions.

Monte Carlo inversion method is applied and crust and upper mantle structure of the Indian Shield across central India is obtained. Crustal structure obtained shows a marked resemblance to the results obtained earlier through body wave study.
Regional variation and frequency dependence ofQβin the crust of the United States
Authors: Mitchell Brian J.
Published: June 2021

abstract

Approximate Lg attenuation coefficient values are determined for paths in eastern North America at periods between 2 and 4 sec where no data were previously available. These new data, together with reported values at a period of 1 sec, are consistent with values predicted by a frequency-dependentent Qβ of the crust in which Qβ varies as ω0.2. The new data are inconsistent with values which would be predicted by models having prominent maxima or minima in Qβ−1 within the period range 1 to 5 sec.

Lg attenuation coefficients were computed for the frequency-independent crustal Qβ models of Cheng and Mitchell (1981) for the Basin and Range Province and Colorado Plateau of the Western United States. The predicted values at 1 sec for the Colorado Plateau and Basin and Range Province are about twice as large, and three times as large, respectively, as those predicted for the Eastern United States. Recently reported values of Q for 1-sec Lg in those regions are consistent with the attenuation coefficients and Q values of Lg predicted by the Colorado Plateau and Basin and Range Province models. A model with a small degree of frequency dependence of Qβ would be consistent, but is not required by the data.
A rare earthquake sequence in the Kobuk Trench, northwestern Alaska
Authors: Gedney Larry , Marshall Dianne
Published: June 2021

abstract

Four moderate earthquakes in the magnitude of 4 to 5 range occurred in the Kobuk Trench of northwestern Alaska during October 1980. This is a characteristically aseismic area. All foci were of shallow depth, and focal mechanism solutions from the three largest events are consistent in indicating right-lateral displacement on a fault trending WNW-ESE. This would be in agreement with mapped faults of Quaternary age in the area.
ELECTRICAL CHARACTERISTIC CLASSIFICATION OF THE PV’S USING SUPPORT VECTOR MACHINES
Authors: SERTTAŞ Fatih , HOCAOĞLU Fatih Onur
Published: June 2021

Photovoltaics have more attraction day by day due to increasing technologies and decreasing prices. However, in practice, the applicants encounter fundamental problems such as shadow effects and degradation. Due to these problems, the amount of produced annual electricity decreases considerably. Moreover, it is not easy to understand if the company's PV satisfies the requirements or is appropriate for the application. In order to solve such problems, it is instructed to examine the electrical characteristics of the modules. An initial task should be the classification of PV modules according to performance results. Here in this study, it is aimed to classify different PV modules, including different output characteristics. It is aimed to show whether it is possible to classify different PV modules including the same output power or not? To find the answer to this question, a test platform is built. 4 different panels are tested on the platform. While the test, the panels produced by different companies split into two groups, each has the same output power. Under a different insulation condition, the test is performed, and the cells' current-voltage curves are constructed. Different statistics are extracted by using this information. Different variations of these statistics are presented to multi-SVM. Finally, accurate classification results are obtained.

Published: June 2021

In this paper, we try to investigate the contribution of digitalization on economic growth in both developed and developing countries over the period 1990-2020. For this end, different econometric tools are applied on a panel dataset. Overall, we show that the digital technologies seem to significantly and positively affect economic growth in both groups of countries. The digitalization impact level tends to differ across countries. Our empirical results also display that the short- and long-term relationship between information and communication technologies and economic growth is well documented. Such results can be useful for policymakers to enhance the digital economy and provide novel channels to develop adequate policies and promote new institutions. So, benefits from digitalization can lead to realize substantial economic growth.

Regulating News and Disinformation on Digital Platforms
Authors: Wilding Derek
Published: June 2021

In February 2021 two initiatives for regulating digital platforms in Australia were implemented. The News Media Bargaining Code (“News Code”) attracted international attention as a legislative means of forcing platforms to pay for news content, while the Australian Voluntary Disinformation and Misinformation Code (“Disinformation Code”) was modelled on an international initiative. Both were developed to meet Government policy formulated in response to Australia’s Digital Platforms Inquiry. Whereas the Inquiry recommended the use of co-regulation, Government policy switched to voluntary codes for both, then to a legislative scheme for the News Code. This article examines the schemes and critiques the policy on which they are based. It applies a conceptual framework to assess the optimum conditions for the use of co-regulation and self-regulation. It finds that a self-regulatory scheme of voluntary codes was never a suitable approach for the News Code, and that the close involvement of the regulator on the Disinformation Code — without a suitable remit or enforcement powers — distorts the self-regulatory model. This can in part be explained by the failure to address well-recognised flaws in the co-regulatory framework for telecommunications and broadcasting, the consequences of which are now being seen in attempts to regulate digital platforms.
Lüks Algısı Bağlamında Reklamda Sanat Eseri Kullanımı: “İnci Küpeli Kız” Reklamları Örneği
Authors: KARŞU CESUR Damla , TOSUN Nurhan Zeynep
Published: June 2021

Kitlesel üretimle birlikte daha erişilebilir olan lüksün günümüzde yeni lüks olarak adlandırılmakta olduğu görülmektedir. Ancak yeni lüks kapsamında markaların, bir yandan kitlelere seslenirken diğer yandan da tüketicide lüks algısı uyandırma noktasında bir açmaza düştüğü fark edilmektedir. Bu sebeple, tüketicide lüks algısı yaratabilmek amacıyla gerek lüks gerekse kitlesel markaların kimi zaman, enderlik ve lüks gibi anlamları doğal olarak bünyesinde bulunduran görsel sanatlar ile çeşitli biçimlerde iş birliklerine gittikleri gözlemlenmektedir. Bu çalışma da, reklamda sanat eseri kullanımını tüketicinin lüks algısı çerçevesinde ele alır. Vermeer’in “İnci Küpeli Kız” adlı eserini biri doğrudan canlandıran ve hedonik mesaj veren; diğeri ise aynı eseri manipüle ederek kullanan ve faydacı anlayışa dayanan iki reklam özelinde gerçekleşen araştırma, reklamda yer verilen sanat eserine yönelik tüketici algısının, reklamı yapılan ürünün lüks algısına yansıyıp yansımadığını yol analizi (path analysis) tekniği aracılığıyla nicel olarak sorgulamaktadır. Bununla birlikte kurduğu aracılık modeliyle araştırma, sanat eserine yönelik algı ile lüks algısı arasındaki potansiyel ilişkiye reklam prestij algısının aracılık edip etmediğini de incelemektedir. Araştırma neticesinde ise reklamda kullanılan sanat eserine yönelik tüketici algısının her iki reklam bazında da reklamı yapılan ürüne yönelik lüks algısını etkilediği, ayrıca reklama yönelik prestij algısının söz konusu ilişkiye aracılık ettiği sonuçlarına ulaşılmıştır.

Published: June 2021

This paper analyzes the relationship of educational skills that students should achieve for each computer programming class using a student self-assessment questionnaire. The questionnaire survey, containing 25 educational skills, was conducted in computer programming classes in my university using a computer-assisted web-interviewing technique. The questionnaire results are analyzed using an agglomerative hierarchical clustering based on Ward’s method and a self-organizing map, which is a machine learning method. This study shows that the students can be classified into four clusters: highly skilled students, students with high learning and thinking skills but low executing skills, students with high leaning and executing skills but low thinking skills, and students with lower skills.

Authors:   the Department of Language Pedagogy and Intercultural Studies at Constantine the Philosopher University in Nitra, Slovakia, Datko Juraj
Published: June 2021

The paper aims to find out the outcomes of homework and bonus activities on Facebook through three categories, namely “participation”, “preference”, and “convenience”. University students (N=34) participated in this research which was conducted in the “English for Academic Purposes 1” course taught by the author. The case study uses statistical data from our Facebook study group and qualitative data from student diaries. The results indicate a moderate-to-high students’ participation in Facebook assignments and that participation in these activities is influenced by reward, effort, study environment, and workload from other subjects. The findings also show that students prefer collaborative tasks.

This study aims to describe the mitigation-based MDMC enlightenment da'wah in handling the impact of the pandemic, especially providing psychological assistance to the COVID-19 survivors' community. Research data were obtained through in-depth interviews, observation, and document review. All data obtained were analyzed using the Miles and Huberman paradigm. The results showed that Muhammadiyah first carried out mitigation-based enlightenment da'wah through various social activities by providing public awareness in dealing with the COVID-19 pandemic. Second, da'wah based on a mitigation approach was carried out by the Southeast Sulawesi MDMC, with three approaches, an oral approach, brochures, and social media. The bil hal or bi al-amal approach was carried out through measured and planned actions, such as spraying disinfectants, distributing masks, sharing food, and providing scholarships to survivors. Third, the enlightenment da'wah based on the mitigation movement conducted by MDMC was inclusive and universally humanitarian oriented. This activity has proven to improve the psychological condition of the COVID-19 survivors. The pandemic period requires physical distancing, but social attachment must be solid because caring for each other can reduce stress levels and make the body's immune stronger.
The Role of Ex Combatants Party Against The Advocacy of Political Representation of Women In The Post-Conflict in Aceh, Indonesia
Authors: Satris Rezki
Published: June 2021

This study discusses the role of ex-combatant parties in advocating post-conflict women by using the Aceh Party case study. Aceh Party is one of the parties that transformed the struggle movement from the armed movement into a political party movement through general elections. The ex-combatant party was formed by post-conflict combatants after peace negotiations. The ex-combatant party which later became the case study material in this study was the ex-combatant party (Aceh Party) in Aceh. The presence of ex-combatant parties as part of the democratization process has a different reception towards the equality discourse of women in the participation and representation of public spaces, especially representation in politics. The Aceh Party has a tendency for women only as a formality to fulfill a 30 percent quota, without involving women seriously in political matters. This certainly can be seen how the party programs tend to be gender biased. The purpose of this study is to look at the phenomenon of the presence of post-conflict ex-combatant parties as part of the democratization process in providing advocacy for women. Through this research with a qualitative approach both sourced from primary and secondary data by tracing various literature, documents, and other supporting materials.

Background: This study aimed to evaluate the efficiency of immunostaining with p16 and Ki-67 in cervical cytology specimens for the detection of cervical intraepithelial neoplasia (CIN) in a high risk population.Methods: This was a prospective review of 287 women who underwent pap smear, human papilloma virus (HPV) testing and colposcopy examination, respectively. There were cervical smear abnormalities in 108 women (37.6%) and 141 patients (49.1%) tested positive for HPV. Cervical biopsy revealed normal cervix in 28 patients (9.75%), cervicitis in 48 patients (16.72%), CIN1 in 178 patients (62.02%), CIN2 in 26 patients (9.05%) and CIN3 in 7 patients (2.43%).Results: Positive staining for p16 had a sensitivity of 78.2% and a specificity of 97.4% while positive staining for Ki67 had a sensitivity of 80.6% and a specificity of 57.9% for distinguishing CIN lesions in cervical cytology specimens (p=0.001 for both). Concurrent positive staining for p16 and Ki67 in cervical cytology specimens had a sensitivity of 80.6% and a specificity of 97.4% for CIN lesions (p=0.001). Positive staining for p16 had a sensitivity of 94% and a specificity of 90.6% whereas positive staining for Ki67 had a sensitivity of 97% and a specificity of 33% for differentiating CIN lesions in colposcopic biopsy specimens (p=0.001 for both). Concurrent positive staining for p16 and Ki67 in colposcopic biopsy specimens had a sensitivity of 91% and a specificity of 94% for CIN lesions (p=0.001).Conclusions: p16/Ki-67 immunostaining applied on cervical cytology specimens can screen CIN lesions with high sensitivity and specificity in a low risk population.

Background: Stillbirth is one of the common adverse outcomes of pregnancy that occur worldwide. The prevalence differs in different continents of the world and even within different localities in the same country. The objective of this study was to determine the prevalence and social determinants of health that affect still birth in Enugu state, Nigeria.Methods: The study was a prospective hospital-based study conducted at the obstetrics and gynecology department of a tertiary health facility in Nigeria. All the data were retrieved from the ante natal and delivery card of all the women that delivered at the unit within the time of data collection. Data was analyzed using SPSS version 25 and variables were presented as frequencies, percentages, means, and standard deviation. Bivariate analysis was done using chi-square test. The level of significance was set at p value≤0.05.Results: The mean age of the mothers was 29.76±4.69 while most of them were aged 21-30 years 431(56.0%). Majority of them were employed 529 (68.7%) and had tertiary education 484 (62.9%). The prevalence of still birth was 40.3 per 1000 births. Maternal age, marital status, educational levels and booking status affected the prevalence of still birth.On logistic regression, un-booked mothers had 25 times odds of having still birth when compared to those that booked after 28 weeks gestationConclusions: The prevalence of still birth is high in Enugu state with un-booked mothers contributing about 88.6%. Early booking helps to detect possible complications early with timely interventions.

Authors: Kruthipati Rashmi , Chethan Radhika , Shiva Anitha Gabbalkaje , Suresh Sukanya
Published: June 2021

Background: Vaginal candidial infections are due to excessive growth of Candida. These are normally present in the vagina in small numbers. Vaginal infections are typically caused by the yeast species Candida albicans. It is found that candidial infection increases the risk of preterm labour. Aims and objectives of the study were to determine the prevalence of vulvovaginal candidiasis and influence of maternal age, parity and weeks of 2nd trimester on its occurrence among pregnant women in 2nd trimester, attending the antenatal clinic in our hospital.Methods: A prospective study conducted in BMCRI for a period of 3 months (October 2019-December 2019) on patients in second trimester. Consent of patients taken. High vaginal swabs were collected from the pregnant patients in second trimester and sent for culture. Candida positive cases were noted and results were analysed.Results: A total of 100 high vaginal swabs were collected and reported in our study. Among them 54 swabs were positive for Candida growth (54%) and 46 swabs were negative for growth (46%). Culture positive patients’ clinical details were analysed and tabulated.Conclusions: Our study concluded that candidiasis is more prevalent in pregnant women but there was no statistical significance in occurrence of vaginal candidiasis among various age groups, parity or trimester. Hence it is better to screen all the patients in I early II trimester in order to find out and treat positive cases early to prevent preterm births attributed to vaginal candidiasis.

Published: June 2021

Background: Utero-placental insufficiency is one of the major causes of oligoamnios and diminished fetal movements (FM). Rapid intravenous isotonic fluid infusion within the cardiovascular reserve improves tissue perfusion in all systems. We tested the hypothesis that isotonic fluid challenge may improve uteroplacental perfusion, which may, in turn improve fetal oxygenation, liquor formation, and FM.Methods: In this descriptive study, twenty-three antenatal mothers with gestational age >26 weeks, and with amniotic fluid index (AFI) <8 cm were included. Intravenous isotonic fluid challenge with 2 or 3 pints of ringer’s lactate, at the rate of 180-200 drops/minute, twice daily for 2-3days and, L-arginine infusion, 300 ml/day alternate days for 2-3 doses were given. Women were advised to take more than 3 litres of water a day. AFI was recorded once daily for 5 days, and then biweekly. The fluid challenge was repeated whenever AFI diminished <8.00 cm. AFI and perceived FM were graded. Pregnancies were terminated when there was no response to fluid challenge. The trend of changes in AFI and FM grades, number of days pregnancies continued, and perinatal outcomes were recorded.Results: We noted recurrent fall in AFI after an initial arise in 20 women, which required recurrent fluid challenges. Pregnancies could be continued for 18±8.5 days (median±SD). Three women, with case of absent FM, reported FM within 1 hour after initiation of the fluid challenge. There were no perinatal deaths.Conclusions: Intravenous isotonic fluid challenge and L-arginine infusion, improves AFI and FM, and helps to prolong pregnancies towards viability.

Background: Menstrual irregularities are common with thyroid disorders. It has been reported that hyperthyroidism the most common manifestation is simple oligomenorrhea and hypothyroidism usually is associated with polymenorrhea. Present study has been designed to evaluate the menstrual and endometrial patterns in women with thyroid disorders in costal Andhra Pradesh.Methods: During the study period of two years and ten months we have enrolled 110 patients with clinical presentation of thyroid disorder with menstrual irregularities as per our study criteria. Based on report patients were divided in to three groups, hyperthyroid, hypothyroid and subclinical hypothyroidism. Based on abnormal menstrual pattern patients were divided in to menorrhagia, oligomenorrhea, polymenorrhea, and amenorrhea groups. Endometrial biopsy was taken from women in perimenopausal age group and histopathological examination was done to know the pattern of endometrium.Results: Subclinical hypothyroidism was present in 24 (21.81%) patients, hypothyroidism was present in 52 (47.27%) patients and hyperthyroidism was present in 34 (30.90%) patients. amenorrhea was present in 26 (23.63%) patients, oligomenorrhea was present in 12 (10.90%) patients, Intermenstrual bleeding was present in 2 (1.81%) patients, Menorrhagia was present in 44 (40%) patients which was most common type of menstrual disorder and Polymenorrhagia was present in 26 (23.63%) patients.Conclusions: Hypothyroidism is most common thyroid disorder followed by hyperthyroidism and subclinical hypothyroidism is least common. We have found that menstrual irregularities are more common in hypothyroid patients than hyperthyroid. Menorrhagia and Polymenorrhagia is more common than amenorrhoea and oligomenorrhea in hypothyroid patients.
