Abstract
Introduction
Given that maternal mortality is a major global health concern, multiple measures including antenatal care visits have been promoted by the global community. However, most pregnant women in Ghana and other sub-Saharan African countries do not attain the recommended timelines, in addition to a slower progress towards meeting the required minimum of eight visits stipulated by the World Health Organization. Therefore, this study explored the trends in antenatal care visits and the associated factors in Ghana from 2006 to 2018 using the Multiple Indicator Cluster Surveys.

Methods
The study used women datasets (N = 7795) aged 15 to 49 years from three waves (2006, 2011, and 2017-2018) of the Ghana Multiple Indicator Cluster Surveys (GMICS). STATA version 14 was used for data analyses. Univariable analyses, bivariable analyses with chi-square test of independence, and multivariable analyses with robust multinomial logistic regression models were fitted.

Results
The study found a consistent increase in the proportion of women having adequate and optimal antenatal attendance from 2006 to 2018 across the women’s sociodemographic segments. For instance, the proportion of mothers achieving adequate antenatal care (4 to 7 antenatal care visits) increased from 49.3% in 2006 to 49.98% in 2011 to 58.61% in 2017-2018. In the multivariable model, women with upward attainment of formal education, health insurance coverage, increasing household wealth, and residing in the Upper East Region were consistently associated with a higher likelihood of adequate and/or optimal antenatal care attendance from 2006 to 2018.

Conclusion
Women who are less likely to achieve optimal antenatal care visits should be targeted by policies towards reducing maternal mortalities and other birth complications. Poverty-reduction policies, promoting maternal and girl-child education, improving general livelihood in rural settings, expanding health insurance coverage and infrastructural access, harnessing community-level structures, and innovative measures such as telehealth and telemedicine are required to increase antenatal care utilization.

Published: January 2022

Abstract
Background
Robotic-arm-assisted knee arthroplasty allows for more accurate component positioning and alignment and is associated with better patient-reported outcomes compared to manually performed jig-based knee arthroplasty. However, what is not known is whether the addition of an intra-articular sensor (VerasenseTM) to aid intraoperative balancing of the total knee replacement (TKR) offers improved functional outcomes for the patient. The purpose of this research is to compare the outcomes of patients undergoing a conventional manual knee replacement to those undergoing TKR using robotic-assisted surgery and the VerasenseTM to optimise alignment and balance the knee joint, respectively, and assess the associated cost economics of such technology.

Methods and analysis
This randomised controlled trial will include 90 patients with end-stage osteoarthritis of the knee undergoing primary TKR. Patients meeting the inclusion/exclusion criteria that consent to be in the study will be randomised at a ratio of 1:1 to either manual TKR (standard of care) or robotic-arm-assisted TKR with VerasenseTM to aid balancing of the knee. The primary objective will be functional improvement at 6 months following surgery between the two groups. The secondary objectives are to compare changes in knee-specific function, joint awareness, patient expectation and fulfilment, satisfaction, pain, stiffness and functional ability, health-related quality of life, cost-effectiveness, and gait patterns between the two groups. Ethical approval was obtained by the Tyne & Wear South Research Ethics Committee, UK. The study is sponsored by the Newcastle Hospitals NHS Foundation Trust.

Discussion
This study will assess whether the improved accuracy of component positioning using the robotic-arm-assisted surgery and the VerasenseTM to aid balancing of the TKR offers improved outcome relative to standard manual jig-based systems that are currently the standard of care. This will be assessed primarily according to knee-specific function, but several other measures will also be assessed including whether these are cost-effective interventions.

BACKGROUND:
Maintaining the patency of extracranial-to-intracranial (EC-IC) bypass is critical for long-term stroke prevention. However, reports on the factors influencing long-term bypass patency and quantitative assessments of bypass patency are limited.

OBJECTIVE:
To quantitatively evaluate blood flow in EC-IC bypass using four-dimensional (4D) flow magnetic resonance imaging (MRI) and investigate factors influencing the long-term patency of EC-IC bypass.

METHODS:
Thirty-six adult Japanese patients who underwent EC-IC bypass for symptomatic internal carotid or middle cerebral artery occlusive disease were included. We examined the relationships between decreased superficial temporal artery (STA) blood flow volume and perioperative complications, long-term ischemic complications, patient background, and postoperative antithrombotic medications in patients for whom STA flow could be quantitatively assessed for at least 5 months using 4D flow MRI.

RESULTS:
The mean follow-up time was 54.7 ± 6.1 months. One patient presented with a stroke during the acute postoperative period that affected postoperative outcomes. No recurrent strokes were recorded during long-term follow-up. Two patients died of malignant disease. Seven cases of reduced flow occurred in the STA, which were correlated with single bypass (P = .0294) and nonuse of cilostazol (P = .0294). STA occlusion was observed in 1 patient during the follow-up period. Hypertension, age, smoking, dyslipidemia, and diabetes mellitus were not correlated with reduced blood flow in the STA.

CONCLUSION:
Double anastomoses and cilostazol resulted in long-term STA blood flow preservation. No recurrence of cerebral infarction was noted in either STA hypoperfusion or occlusion cases.

Background. Earlier, we found a close correlation between EEG and gas-discharge image (GDI) parameters. The aim of this study is to analyze the relationship of EEG parameters with the energy and asymmetry of virtual chakras, reconstructed on the basis of GDI parameters. Material and Methods. We observed twice 31 women and 29 men aged 26-76 years with dysfunction of neuroendocrine-immune complex. In the morning in basal conditions at first registered GDI by the method of GDV by the device “GDV Chamber” (“Biotechprogress”, SPb, RF). Than we registered EEG. Results processed by method of canonical analysis, using the software package “Statistica 64”. Results. The coefficients of canonical correlation between the EEG parameters and virtual Chakras Energy are in the interval 0,415÷0,564 and 0,358÷0,528 when registering without a filter and with a filter, respectively. Additional inclusion of HRV and endocrine parameters increases the strength of the canonical correlation to 0,768 and 0,772, respectively. The coefficients of canonical correlation between the EEG parameters and individual virtual Chakras Asymmetry are in the interval 0,284÷0,634 and 0,152÷0,458 when registering without a filter and with a filter, respectively. Integral coefficient of the canonical correlation is 0,820. Conclusion. The above data, taken together with the previous ones, state that between parameters of neuroendocrine-immune complex and GDV exist strong canonical correlation suggesting suitability of the latter method.

Published: January 2022

El presente texto analiza la relación entre el mundo indígena, la cinematografía documental y el audiovisual como artefactos de representación en Colombia. Mediante una selección y revisión historiográfica de películas documentales que visibiliza títulos representativos de cada periodo, se analizó la intrincada relación entre la antropología visual, la identidad indígena y sus estrategias comunicativas, la evolución de los procesos de representación y la intensa vinculación de todos estos factores con el cine documental de corte etnográfico. Todo en un contexto histórico y social complejo, afectado por numerosos factores. Esta evolución contribuye a explicar las características actuales del cine documental de corte etnográfico en Colombia, conectado con el documental de autor en un momento en el que el discurso reflexivo se ha instalado en el formato documental. Hay que resaltar el papel que ha desempeñado el cine documental como formato por excelencia para la representación de las poblaciones indígenas. La evolución general de la cinematografía documental colombiana y latinoamericana, así como las transformaciones que han sufrido los enfoques teóricos en la antropología visual frente al objeto de estudio, han influido en la configuración de un tipo de cine que hoy enfrenta grandes retos en cuanto a las formas de representación.

Abstract. Kurniawan FH, Nazar L, Anjarwati R, Sasono HD, Rahayuningsih M. 2021. Orchids of Mount Ungaran (Indonesia) compiled from a decade of data collections between 2010 and 2021. Nusantara Bioscience 13: 245-259. Orchid is well known as a plant group widely used as ornamental plants because of their uniqueness. But, high exploitation, deforestation, and land-use changes have threatened orchid species and triggered extinction. It also happened in Mount Ungaran, Central Java, Indonesia, despite designation as an essential ecosystem area. This research was conducted to add an updated list of wild orchid species that can serve as biodiversity baseline data for conservation management in Mount Ungaran. The study was carried out through exploration activities from 2010 to 2021. The study area covered eleven sites namely Gentong Hills, Kalisidi, Pasigitan, Banyuwindu, Gajahmungkur, Watuondo, Mawar Camp, Indrakila, Gondang and Puncak which were all included in the buffer zone of Mount Ungaran. A total of 115 species from 54 genera of orchids were successfully identified, including 78 species of epiphyte and 37 species of terrestrial orchids. Among the species recorded, at least 27 species were known to be endemic to Indonesia, and 8 species were endemic to the island of Java, which four species were listed in the IUCN Red List. In addition, all the species found were listed in Appendix II of the CITES, except one species, Paphiopedilum javanicum which was listed in Appendix I. This study recorded the new distribution records of several species of orchids that were previously only found in West Java or East Java, i.e., Ania penangiana, Pholidota convallariae, and Crepidium junghuhnii. This study has also documented a species from genus Crepidium, which morphological characters have not been described in any identification guides. The Gentong area has potential as a priority for in-situ orchid protection area by the highest number of species were reached 54% of all orchids found on Mount Ungaran.

Endocarditis tricuspídea secundaria a infección asociada a catéter venoso central. Reporte de dos casos
Authors: Salamanca Max A. 
Published: January 2022

Se describen a dos pacientes portadores de catéteres intravasculares que desarrollaron una complicación grave como la endocarditis infecciosa secundaria a infección asociada al catéter. Estos pacientes tuvieron una buena resolución mediante antibioticoterapia y retiro del catéter infectado sin necesidad de llegar a cirugía cardiaca. Las infecciones asociadas al catéter vascular son complicaciones frecuentes en los portadores de catéteres vasculares que conllevan a posibles consecuencias graves como bacteriemia o fungemia pues funcionan como vía de entrada para gérmenes que pueden infectar un órgano noble predispuesto. Por lo tanto, el presente reporte de casos remarca la importancia de considerar a la endocarditis como una complicación latente en pacientes con riesgo infeccioso asociado a los catéteres intravasculares y cómo evitar el uso innecesario de un catéter venoso central.

Authors: Santa Cruz-Vega Katia , Huamán-Gutiérrez Oscar 
Published: January 2022

Objetivos. Evaluar el efecto de la harina de Myrciaria dubia (camu camu) sobre el tejido hepático inducido a toxicidad por acetaminofén en ratones. Métodos. Diseño experimental. Se preparó una suspensión de harina de camu camu (HCC) con almidón al 1,6%. Se emplearon 40 ratones machos de la cepa BALB/c, con un peso promedio de 30,8 g y de dos meses de edad, los cuales fueron divididos en cinco grupos, recibiendo el siguiente tratamiento, vía orogástrica, por un período de 10 días, grupos I y II: almidón 1,6% 10 mL/kg; grupo III: HCC 200 mg/kg, grupo IV: HCC 500 mg/kg y grupo V: HCC 800 mg/kg. Al 6to día de tratamiento se le administró acetaminofén (300 mg/kg) a los grupos II-V hasta el 10mo día. Terminada la intervención los animales fueron puestos en ayunas de 12 horas, para luego ser sacrificados previaanestesia con pentobarbital sódico. Se extrajo el hígado, se identificó y seccionó el lóbulo mayor para el estudio bioquímico e histológico. Resultados. La harina de camu camu redujo los niveles del índice hepático, y presentó un mejor perfil del sistema glutatión, comparado con el grupo II; sin embargo, las cifras de lipoperoxidación no mostraron diferencia significativa. A nivel histológico, en los grupos que recibieron HCC se observaron hepatocitos binucleados, así como un mayor mantenimiento de la polaridad; sin embargo, algunas muestras evidenciaron microvacuolas y leve fragmentación de la cromatina. Conclusión: La harina de camu camu evidenció efecto hepatoprotector frente a la toxicidad por acetaminofén en ratones.
Strain-ageing effects on the residual low-cycle fatigue life of low-carbon steel reinforcement
Authors: Loporcaro Giuseppe , Cuevas Alberto , Pampanin Stefano , Kral Milo V. 
Published: January 2022

AbstractLow-cycle fatigue (LCF) failures can be expected when rebars are subjected to a small number of cycles at large stress/strain amplitudes. Major seismic events are often preceded or followed by other events of smaller/larger magnitude. During each event, the residual fatigue life of the steel reinforcement may reduce, eventually leading to failure of the bars due to the cumulative damage. Strain ageing may reduce even more the residual fatigue life of steel. This paper presents the results of an experimental testing campaign conducted on samples fabricated from New Zealand Grade 300E steel. A benchmark LCF life was obtained for 12-mm steel reinforcing bars subjected to axial-strain-controlled completely reversed cyclic tests at amplitudes ranging between 0.78 and 2.75%. The reduction in fatigue life attributed to strain ageing was obtained by comparing the benchmark fatigue life with that of steel reinforcing bars precycled up to 33% and 66% of the benchmark life and artificially strain aged for an equivalent period of 1 year at 15 °C. The Coffin-Manson and Koh-Stephens models were employed to evaluate the experimental results. The study demonstrates that, depending on the strain amplitude, strain ageing can cause a reduction in total and residual fatigue life ranging from 20 to 70%. Strain ageing should not be ignored during the assessment of earthquake-damaged steel reinforcing bars.
Hebephrenia Hecker-Kahlbaum and E. Kraepelin's teaching on dementia praecox
Authors: Obraztsov Vladimir N. 
Published: January 2022

In the 90s of the last century, to the arena of clinical psychiatry, the former Heidelberg, now Munich, prof. E. Kraepelin put forward a group of mental disorders under the name "dementia praecox" - early or premature dementia.
Since then, the question of dementia praecox has not left the pages of psychiatric literature; it is dealt with at conferences, special journals are devoted to it, but despite the 20-year existence of the issue, which grew in the Kraepelin's school into a whole doctrine, even now it cannot be considered definitively resolved.

Authors: MEHDI SYED HASAN 
Published: January 2022

The human being is the noblest of all the creations by Allah Rabbul-Izzat. Allah gave special commands to humans which made differences over other species, the hygiene practice is one of them. The researches on toilets, defecation, urination and self-cleansing may be supposed as unthinkable subjects in daily discussions, but these topics are important for health and hygiene perspectives. Designers and manufacturers are busy making aesthetically attractive, ergonomically and anthropometrically defined toilet seats. But there is a need for some adjustments in the size and design of modern toilet seats as per the hygiene perspective. This paper presents a conceptual design framework aimed, increasing the level of hygiene and introduced the three-dimensional designs of sitting and squatting types of toilet seats with some amendments as compared to modern designs, concerning hygiene perspective. The present conceptual design of toilet seats can become the integration of human hygiene practice. In this study, Solidworks Designing Software was used for three-dimensional designs. This framework study dedicates to Iranian society.
Region based Feature Fusion of Imperfect Face and Gait cues for human recognition using Median-LBPF and Median-LBPG based PCA followed by LDA
Authors: K Annbuselvi , N Santhi , Sivakumar Dr.S. 
Published: January 2022

Abstract— Conventional computer-based multimodal biometric systems for human recognition based on face and gait cues are mainly based on recognition of perfect images of face and gait. There are situations, where perfect face and gait images may not be available which means probe images are imperfect. This paper proposes new methods Median Local Binary Pattern of Face image (Median-LBPF) and Gait image (Median-LBPG) to extract the features of imperfect face and gait images efficiently representing such imperfect images for better recognition. Initially the given imperfect face and gait images are divided into six overlapped regions called top, bottom, left, right, vertical center, horizontally center overlapped half images. The features of these six overlapped regions of imperfect face and gait images in the spatial domain are extracted by using Median-LBPF and Median-LBPG. Subsequently the dimensionality of the feature sets are reduced by a two stage feature reduction algorithms Principal Component Analysis (PCA) followed by Linear Discriminant Analysis (LDA). Next the individual face features and gait features are normalized to have their values lie within similar ranges and are concatenated at feature level. For classification, Euclidean distance measure is used to calculate the minimum of minimum distance between the six overlapped regions of given imperfect face and gait probe images and the corresponding regions of all six overlapped regions in the training sets. The proposed methods are tested by using publically available data sets ORL face and CASIA gait. The experimental results show that features of a region of face and gait images are adequate for recognition and its average recognition performance is same as perfect face and gait images.
