A practical review of watch-and-wait approach in rectal cancer
Authors: Byun Hwa Kyung , Koom Woong Sub
Published: March 2023

Rectal resection surgery after neoadjuvant treatment has been the mainstay treatment of locally advanced rectal cancer. However, functional outcomes and quality of life after radical resection of the rectum remain suboptimal. The excellent oncologic outcomes in patients who achieved pathologic complete response after neoadjuvant treatment questioned the need for radical surgery. The watch-and-wait approach is a noninvasive therapeutic alternative for organ preservation and avoiding operative morbidity. In the watch-and-wait approach, patients with locally advanced rectal cancer who achieve excellent clinical response after neoadjuvant treatment undergo active surveillance rather than rectal cancer surgery. In this practical review, we summarized the main results of studies on the watch-and-wait approach and provided a practical method for implementing the watch-and-wait approach.
Le partage de données à l’échelle transfrontalière : analyse de dispositifs médiatiques de surveillance épidémiologique
Authors: Hermand Marie-Hélène
Published: March 2023

Cet article s’intéresse au processus de territorialisation et de présentation des données épidémiologiques à l’échelle transfrontalière. Après avoir identifié les discours qui légitiment le domaine de l’épidémiologie transfrontalière, nous étudions un corpus de neuf dispositifs médiatiques de surveillance épidémiologique transfrontalière. L’analyse discursive et sémio-pragmatique est complétée par des entretiens. Les résultats permettent de dégager les enjeux du partage transfrontalier de données épidémiologiques, de pointer la prolifération des dénominations des dispositifs, de dégager un principe d’organisation sémiotique et de mettre en évidence les logiques d’acteurs. La conclusion propose d’approfondir deux problématisations : le déséquilibre informationnel et l’articulation des compétences spécialisées.

L’article porte sur les mentions du poivre dans les traités de médecine et de pharmacologie rédigés en grec sur une longue période allant du v e siècle avant notre ère jusqu’au ii e  siècle de notre ère. Il envisage ainsi l’usage thérapeutique en termes de rupture et de continuité, à travers une série de questions : quel type de poivre utilisaient les médecins ? Quelle préparation et quelle voie d’administration préconisaient-ils, et à quelle fin thérapeutique ? Cet ingrédient était-il facilement accessible à leurs contemporains ? Quelle était sa valeur dans l’imaginaire collectif et quel était son statut dans la pharmacopée grecque antique ?

Nous avons parfois la chance de pouvoir suivre l’histoire d’un mot sur la longue durée et à travers l’espace. C’est ce qui est entrepris ici, dans cet article, avec le mot tamoul ancien kaṟi « poivre », dont nous pouvons suivre la trace dans la littérature tamoule sur environ deux millénaires et dont un avatar moderne, mondialement connusous une orthographe anglaise, est le « curry », qui symbolise pour beaucoup la cuisine épicée de l’Inde. Grâce à l’effort soutenu pendant de nombreux siècles des lettrés puis des philologues tamouls nous avons accès à 26 occurences du mot kaṟi dans le corpus de 2362 poèmes tamouls anciens qui est généralement connu sous le nom de « littérature du Sangam ». Nous pouvons également suivre ce terme dans la littérature postérieure, qui contient un important sous-ensemble dévotionnel, ainsi que dans la littérature technique, et tout spécialement dans plusieurs thesauri anciens. Nous entrapercevons, à travers toutes ces attestations, la réalité botanique d’une plante, aussi connue sous le nom de miḷaku , son importance pour le commerce, ainsi que son rôle symbolique, en tant que représentant éminent du paysage de montagne, qui est l’un des cinq paysages traditionnels, dans un ensemble de conventions poétiques codées.
Le poivre, fragments d’histoire globale
Authors: Ménard-Jacob Marie
Published: March 2023

Quand la Compagnie des Indes est créée en 1664, le poivre fait partie des produits contenus dans son monopole. Ainsi, un demi-siècle après les autres Européens, les Français investissent la côte ouest de la péninsule indienne avec les comptoirs de Tilcéry et Rajapour, et l’Asie du Sud-Est avec celui de Bantam. En outre, à partir de 1681, surgit un projet politique, religieux et militaire dans le royaume du Siam dont le poivre constitue le prétexte commercial. Aucune de ces entreprises n’est couronnée de succès. Paradoxalement, malgré ces multiples échecs, le poivre, tout au long du xvii e  siècle, garde une place dans les cargaisons françaises et apparaît à l’aube du siècle suivant comme un produit stratégique et nécessaire.
La problématique du conflit père/fils dans le malaise et la thérapie d’une famille camerounaise
Authors: Mboua Célestin Pierre , Nguepy Keubo François Roger
Published: March 2023

Les thérapies systémiques familiales restent peu pratiquées au Cameroun et en Afrique. Ceci s’explique souvent par le fait que les modèles transactionnels familiaux traditionnels, de nature asymétrique, restent vivaces. Ils sont véhiculés à travers les mythes et rituels qui organisent la vie des familles, malgré la diversité des espaces de socialisation et d’enculturation qui se proposent à l’idiosyncrasie des générations actuelles. Ceci est souvent à l’origine de crises ou pannes du fonctionnement familial. Les thérapeutes eux-mêmes, sont souvent porteurs de ces modèles inconscients dans leurs interventions et leurs pratiques, qui agissent comme des contraintes à la formation et l’exercice des thérapies systémiques. L’article présente et analyse la prise en charge d’une famille dont les difficultés transactionnelles, portées par la mère, sont des symptômes d’une crise du fonctionnement familial dont le conflit père/fils est le nœud. L’observation clinique suggère que la famille négocie péniblement la transition entre traditions et modernité. La réponse proposée est une approche systémique-fonctionnelle conduisant à une réorganisation autonome et guidée du fonctionnement familial, laquelle a montré son efficacité dans la disparition des symptômes névrotiques chez le malade désigné.
Quelles évolutions dans la prise en compte du vieillissement des personnes en situation de handicap par les politiques publiques en France ?
Authors: Ennuyer Bernard
Published: March 2023

Dans les années 1980, l’augmentation spectaculaire de l’espérance de vie des personnes en situation de handicap a posé la question de leurs lieux et de leurs modes de vie après 50 ans. C’est ainsi que les établissements et services médicosociaux pour « adultes handicapés » se sont trouvés dépourvus devant cette avance en âge. Les professionnels de terrain et les familles des personnes en situation de handicap ont fait face en « bricolant » localement des réponses, soit à domicile, soit en institution. Les politiques publiques ont tardé à prendre en compte cette évolution, mais la politique publique en direction du champ du handicap a quand même bougé. Ce que les personnes en situation de handicap vieillissantes ont surtout mis en évidence, c’est l’incapacité des « politiques vieillesse » à satisfaire leurs souhaits en matière de modes et de lieux de vie. De ce fait, elles ont surtout mis en lumière, de façon plus générale, l’incapacité des « politiques vieillesse » actuelles à répondre aux besoins de toutes les « personnes âgées en incapacité ». En 2020, l’avance en âge des personnes en situation de handicap a donc contribué, parmi beaucoup d’autres facteurs, à la promesse législative de la création d’une nouvelle branche de Sécurité sociale, la branche Autonomie, pour répondre au besoin d’accompagnement de toutes les personnes « indépendamment de leur âge et de leur état de santé ». L’opérationnalité rapide de cette branche Autonomie pilotée par la cnsa et son financement pérenne doivent devenir une des priorités de l’actuel gouvernement.

Botulinum toxin A injection is a safe alternative procedure to surgery in the management of different types of strabismus. Serious complications such as globe perforation are rare in expert hands. The authors report a case of a child known to have a muscle-eye-brain disease with high myopia who developed endophthalmitis following inadvertent penetrating intraocular botulinum toxin A injection for strabismus correction. To their knowledge, this serious complication after penetrating botulinum toxin A injection has not been previously reported.

On Mereology and Metricality
Authors: Perry Zee R
Published: March 2023

This article motivates and develops a reductive account of the structure of certain physical quantities in terms of their mereology. That is, I argue that quantitative relations like "longer than" or "3.6-times the volume of" can be analyzed in terms of necessary constraints those quantities put on the mereological structure of their instances. The resulting account, I argue, is able to capture the intuition that these quantitative relations are intrinsic to the physical systems they’re called upon to describe and explain.
Decolonization and the Right to Self-Determination
Authors: Shikova Natalija
Published: March 2023

Self-determination has been defined as the right of people to freely determine their political status and pursue their economic, social, and cultural development. During decolonization, the right aimed towards the establishment of the self-government for the peoples – inhabitants of nonself-governed colonial territories. Over the last half century, the process of decolonization resulted in a successful attainment of formal sovereignty for the former colonies. However, the liberation movements reached self-determination externally but failed to reach it internally. Since the process of decolonization is formally over, there is a change in a right holder and the mode for practicing self-determination. Except for an aggregate population – people within the state that can practice an external form of self – determination, as a process internal self-determination can be granted to different subnational groups. The ones that reached external self-determination should accept legal norms that grant forms of internal self-determination.

Published: March 2023

In this monocentric, open label, randomized controlled trial we aimed to compare the efficacy of combined High Flow Nasal Cannula (HFNC) and Non invasive Ventilation (NIV) versus HFNC alone in acute hypoxemic respiratory failure (hARF) in patients affected by Community Acquired Pneumonia (CAP). We enrolled 49 patients affected by CAP with moderate to severe hypoxemic respiratory failure (P/F < 300). The patients were randomized into two groups: one has been treated with HFNC alone (group A) while the other received NIV alternated to HFNC every 3 hours (group B). The primary outcome was P/F change from baseline to 21 hours. Secondary outcomes included variation of pH and pCO2, need to continue HFNC or NIV/HFNC after 45 hours, orotracheal intubation, mortality rate, and the devices comfort. Not statistical significant differences between the two arms were shown in the P/F change at 21 hours since baseline, in pCO2 and pH variation, mortality at hospital and at follow-up. We emphasize the importance of combined HFNC with NIV as a first step for severe pneumonia treatment whereas HFNC might represent as the first step treatment in less severe patients and during the NIV intervals.
Ultrasound assessment of diaphragmatic dysfunction and its improvement with levosimendan in patients with chronic obstructive pulmonary disease
Authors: De Rosa Clarissa Anna , Cristiano Giovanna , Guarino Mario
Published: March 2023

Diaphragmatic Dysfunction (DD) is a clinical condition in which the diaphragm becomes weak or paralyzed, because of muscle strength reduction. It can be due to muscular issues or loss of proper innervation, but, also, to pulmonary hyperinflation or air trapping, such as in Chronic Obstructive Pulmonary Disease (COPD). DD impacts on COPD induced dyspnea, determining its progressive worsening, but levosimendan, an inodilator better known as Ca2+ sensitizer, may limit this phenomenon and diaphragmatic ultrasound assessment can be useful in monitoring its effect. Here, we show the case of a 77-year-old woman admitted to the Emergency department for acute exacerbation of chronic dyspnea in COPD, related to right ventricular failure and DD, which did not respond to medical therapy and non-invasive mechanical ventilation but did experience a favorable outcome after intravenous administration of levosimendan.

Cardiovascular toxicity in breast cancer patients – contributors and role of cardioprotective drugs
Authors: Martins Carvalho Miguel , Alves Pinto Ricardo , Proença Tânia , Costa Inês , Tavares Nuno , Paiva Mariana , Sousa Carla , Macedo Filipe
Published: March 2023

Breast cancer (BC) patients treated with anthracyclines and/or anti-HER2-targeted therapies (AHT) are highly associated with cardiovascular toxicity (CVT). Our objective was to evaluate the risk of CVT secondary to cancer treatment and the role of cardioprotective-drugs (CPD) in BC patients. We collected a retrospective cohort of females with BC treated with chemotherapy and/or AHT from 2017 to 2019. CVT was defined as LVEF<50% or decline ≥10% during follow-up. As CPD, we considered renin-angiotensin-aldosterone-system inhibitors and beta-blockers. A subgroup analysis of the AHT patients was also performed. A total of 203 women were enrolled. The majority had high or very-high CVT risk score and normal cardiac function at presentation. As for CPD, 35.5% were medicated pre-chemotherapy. All patients were submitted to chemotherapy; AHT were applied to 41.7%. During a 16 months follow-up, 8.5% developed CVT. There was a significant decrease of GLS and LVEF at 12-months (decrease of 1.1% and 2.2%, p<0.001). AHT and combined therapy were significantly associated with CVT. In the AHT sub-group analysis (n=85), 15.7% developed CVT. Patients previously medicated with CPD had a significative lower incidence of CVT (2.9% vs 25.0%, p=0.006). Patients already on CPD presented a higher LVEF at 6-months follow-up (62.5% vs 59.2%, p=0.017). Patients submitted to AHT and anthracycline therapy had higher risk of developing CVT. In the AHT sub-group, pre-treatment with CPD was significantly associated with a lower prevalence of CVT. These results highlight the importance of cardio-oncology evaluation and strengthen the value of primary prevention.
Effects of adding functionalized graphene oxide nanosheets on physical, mechanical, and anti-biofilm properties of acrylic resin: In vitro- experimental study
Authors: Teimoorian Mehran , Mirzaie Maysam , Tashakkorian Hamed , Gholinia Hemmat , Alaghemand Homayoon , Pournajaf Abazar , Ghorbanipour Reza
Published: March 2023

Background:

Polymethyl methacrylate resin is widely used in orthodontic treatments. Graphene oxide (GO) has reactive functional groups on its surface that facilitate binding to various materials such as polymers, biomolecules, DNA, and proteins. This study aimed to investigate the impact of adding functionalized GO nanosheets on the physical, mechanical, cytotoxicity, and anti-biofilm properties of acrylic resin.

Materials and Methods:

In this experimental study, fifty samples (for each test) were divided into groups of 10, in the form of acrylic resin discs with concentrations of 0, 0.25, 0.5, 1, and 2 weight percentage (wt%) of functionalized GO nanosheets and also the control group. Samples were evaluated in terms of physical properties (surface hardness, surface roughness, compressive strength, fracture toughness, and flexural strength), anti-biofilm properties (On four groups of micro-organisms, including Streptococcus mutans, Streptococcus sanguis, Staphylococcus aureus, and Candida albicans), and cytotoxicity. Data were analyzed using SPSS software version 22, descriptive statistics, one-way analysis of variance test, and Tukey post hoc test. The significance level was considered P < 0.05.

Results:

No significant difference was observed between the different groups with weight percentages of 0.25, 0.5, 1, and 2% nano GO (nGO) and the control group (without nGO) in terms of surface roughness and toughness. However, compressive strength, three-point flexural strength, and surface hardness showed significant differences between the groups. Furthermore, the degree of cytotoxicity increased by increasing the weight percentage of nano-GO.

Conclusion:

The addition of functionalized nGO in appropriate concentrations to polymethyl methacrylate can improve the anti-bacterial and anti-fungal biofilm properties without changing or increasing their physical and mechanical properties.

Authors: Elline Elline , Ismiyatin Kun , Budhy Theresia Indah
Published: March 2023

Background:

Biodegradable hydrogel scaffold is one of the crucial characteristics that determine the success of pulp regeneration. The degradation should be suitable for the growth of new tissue establishment. The aim of this study is to synthesize and compare the novel biodegradable hydrogel scaffold based on hydroxyapatite (HAp) eggshell, collagen, and epigallocatechin-3-gallate (HAp-Col-EGCG) with different HAp concentrations in vitro.

Materials and Methods:

This study is original research. HAp-Col-EGCG hydrogel scaffolds were prepared using 1:1, 1:2, and 1:4 ratios of collagen and HAp with 10 μmol/L EGCG. The samples were freeze-dried and immersed in phosphate buffer saline containing lysozyme enzyme. The dried samples were weighed to determine the percentage of biodegradation value (P < 0.05).

Results:

The result showed HAp-Col-EGCG was biodegradable but it has not been concluded that it can be completely eliminated. The data were analyzed by one-way analysis of variance and it indicated significant differences in percentage values.

Conclusion:

Hydrogel scaffold based on HAp-Col-EGCG can be degraded and have the potential to be used as a biodegradable scaffold in supporting tissue regeneration.
Antimicrobial properties of glass-ionomer cement incorporated with zinc oxide nanoparticles against mutans streptococci and lactobacilli under orthodontic bands: An in vivo split-mouth study
Authors: Shirazi Maryam , Qazvini Fatemeh Fotoohi , Mohamadrezaie Saeed
Published: March 2023

Background:

The aim of this study was to assess the effect of incorporation of zinc oxide nanoparticles (ZnO-NPs) to glass-ionomer cement (GIC) (Fuji II SC, GC Corp., Tokyo, Japan) on subgingival accumulation of mutans streptococci and lactobacilli under orthodontic bands.

Materials and Methods:

In order to conduct this in vivo split-mouth study, 20 patients aged between 7 and 10 years who required lingual holding arch on their mandibular first molars were divided into two groups. In one group, Fuji II SC GIC was used for cementation of the right molar band, and the same cement containing 2 wt% ZnO-NPs was used for the left one. The opposite was performed for the second group while the operator was blinded to the cement types. Subgingival microbial sampling was performed 16 weeks after cementation of lingual arch. Mutans streptococci and lactobacilli colony counts were compared. Paired t-test was used to compare the two cement groups. Data were analyzed using SPSS version 21, and P ≤ 0.05 was considered statistically significant.

Results:

The mean colony counts of mutans streptococci, lactobacilli, and total bacterial count in Fuji II SC containing ZnO-NPs were significantly lower than the corresponding values in plain Fuji II SC group.

Conclusion:

Incorporation of ZnO-NPs into GIC reveals antimicrobial features against mutans streptococci and lactobacilli under orthodontic bands.
COVID–19 vaccination and associated factors in Turkish healthcare workers practicing chest medicine
Authors: Sandal Abdulsamet , Cifci Aylin Güngör , Arbak Peri M
Published: March 2023

Objective:

To evaluate the COVID-19 vaccination status and related characteristics of Turkish healthcare workers practicing chest medicine.

Methods:

A cross-sectional online survey was conducted among the Turkish Thoracic Society members. The survey was started on May 17, 2021, and kept open for seven weeks. The 39-item survey included the COVID-19 vaccination status and demographic, clinical, and occupational characteristics.

Results:

Of 378 healthcare workers participated in the survey, 354 (93.7%) reported receiving at least one dose of the COVID-19 vaccine. A total of 323 (91.2%) healthcare workers received CoronaVac vs. BioNTech/Pfizer in 31 (8.8%). In the CoronaVac group, 77 (23.8%) contracted COVID-19 when not fully vaccinated, and 13 (4.0%) when fully vaccinated; however, 16 (51.6%) healthcare workers in the BioNTech/Pfizer group got COVID-19 when not fully vaccinated, but any fully vaccinated participants did not contract COVID-19 (P=0.003). Regarding vaccine dosing, 328 (86.8%) were fully vaccinated, while 50 (13.2%) were not. Multiple regression analysis for being a non-fully vaccinated healthcare worker demonstrated a significant relationship with having any SARS-CoV-2 infection history (adjusted OR 9.57, 95% CI 3.93-23.26, P<0.001) and being a non-physician healthcare worker (adjusted OR 5.86, 95% CI 2.11-16.26, P=0.001), but a significant negative relationship with full-time working at the time of survey (adjusted OR 0.13, 95% CI 0.03-0.56, P=0.006).

Conclusions:

Although a majority of healthcare workers were fully vaccinated, occupational and non-occupational characteristics were related to being non-fully vaccinated. Active surveillance regarding the COVID-19 vaccination in healthcare workers is necessary to address specific parameters as barriers to vaccination.
Knowledge, perceptions, and practice towards adverse events following immunization surveillance among vaccination workers in Zhejiang province, China
Authors: Lv Huakun , Pan Xuejiao , Wang Ying , Liang Hui , Yu Hu
Published: March 2023

Objective:

To access the level of knowledge, perceptions, and practice towards adverse events following immunization (AEFI) surveillance among vaccination workers in Zhejiang province, China.

Methods:

This was a cross-sectional survey involving 768 vaccination workers. Data were collected using self-administered questionnaires and analyzed by using SAS 9.3 software. Knowledge, perceptions, and practice on AEFI surveillance were summarized using frequency tables. The mean±SD value was used as the cut-off for defining good (values≥mean) and poor (values<mean) knowledge, perceptions or practice. Binary logistic regression analysis was used to determine sociodemographic variables associated with knowledge, perceptions, and practice towards AEFI.

Results:

The proportions of good knowledge, perceptions and practice on AEFI surveillance were 78.13%, 57.81% and 66.15%, respectively. Having a higher education background, longer years of experience, previous training on AEFI and ≥30 years of age were factors associated with good knowledge, perceptions and practice on AEFI surveillance among vaccination workers.

Conclusions:

Over half of the respondents had good knowledge, perceptions and practice on AEFI surveillance work. Interventions on improving the vaccination workers’ knowledge, perceptions and practice on AEFI surveillance should be considered in order to develop a more effective surveillance system.
Dengue and falciparum malaria co-infection in travelers returning from Burkina Faso
Authors: Mastroianni Antonio , Vocale Caterina , Sambri Vittorio , Lazzarotto Tiziana , Gaibani Paolo , Rossini Giada , Varani Stefania
Published: March 2023

Rationale:

Malaria and dengue are the most prevalent vector-borne diseases in tropical countries. Plasmodium parasite and dengue virus (DENV) concurrent infection is possible and often under-recognized in geographical areas where these infections are both endemic.

Patients concern and diagnosis:

We describe the first two cases of Plasmodium falciparum and DENV-3 co-infection in travelers returning to northeastern Italy from Burkina Faso during 2013-2014.

Interventions:

Malaria infection in both patients was treated with mefloquine. Due to the persistence of symptoms despite of the antimalaria treatment, dengue was also investigated; the treatment of dengue was symptomatic.

Outcomes:

The patients were discharged in good general condition.

Lessons:

The need for surveillance of potential malaria and dengue co-infection in travelers returning to Europe from endemic areas is highlighted, as infection with Plasmodium does not exclude arboviral co-infection.

Published: March 2023

Neurologists address diagnosis, modification of disease course and management of symptoms of people with long-term neurological conditions such as Parkinson’s disease, multiple sclerosis, motor neuron disease and sequelae of stroke. Neurorehabilitation specialists focus on management of symptoms and alleviation of activity limitations. Palliative care specialists are involved in end-of-life care of these patients. Guidance and protocols of palliative care services have been directed towards the care of patients with cancer. While it may be possible to extrapolate some of these to people with long-term neurological conditions, there are obvious differences between the two groups. The time course of progressive neurological conditions varies widely between and within the disorders which make timing of initiation of these discussions challenging. Common issues during end-of-life care are when to start discussions about end-of-life care, advanced care planning, management of common symptoms, withdrawal of life-sustaining treatments, support for family and caregivers and when to involve specialist palliative care team. The unique social, economic and cultural aspects of India influence these decisions. End-of-life care cannot be seen in isolation and as such close collaboration between neurology, neurorehabilitation and specialist palliative care is imperative. In this article, we will discuss the end-of-life care of people with long-term neurological condition in India.
Vocal Habits, Dysphonia Severity Index, and Voice-Related Quality of Life in Indian Primary School Teachers
Authors: Khateeb Zaiba , Narasimhan S. V.
Published: March 2023

Context:

Only a handful of studies have explored the relationship between vocal habits, Dysphonia Severity Index (DSI) scores, and Voice-Related Quality of Life (VRQOL), especially among Indian primary school teachers.

Aims:

We aimed to document the factors affecting DSI and VRQOL scores among Indian primary school teachers and to study the correlation between these measures in Indian teachers with and without dysphonia.

Settings and Design:

This was a retrospective standard group comparison study.

Subjects and Methods:

A total of 90 primary school teachers (33 males and 57 females) were administered a vocal health questionnaire, and based on the questionnaire responses, participants were classified into two groups. Group 1 consisted of 33 participants without any self-reported symptoms of voice problems. Group 2 included 57 participants with self-reported symptoms of voice problems. Further, the phonation samples were recorded, and DSI scores were calculated. Participants were also instructed to fill out the VRQOL questionnaire.

Statistical Analysis Used:

Shapiro-Wilk test, the Mann-Whitney U-test, and Spearman's rank correlation coefficient were carried out as a part of statistical analyses.

Results:

Teachers with self-reported vocal symptoms exhibited more frequent habits such as consumption of beverages, intake of spicy and oily food, less time interval between intake of meals and sleep, coughing, speaking at uncomfortable volumes, and frequent screaming or yelling or cheering. There was a significant positive correlation between VRQOL and the DSI values.

Conclusion:

Future studies can be carried out to discern the impact of the classroom's size, population, background noise, and amplification equipment on teachers.
Medial Olivocochlear Functioning and Speech Perception in Noise in Individuals with Polycystic Ovary Syndrome
Authors: Kumar Durga S. , Mahendra Saranya , Devi N. , Jain Chandni
Published: March 2023

Introduction

The current study aimed to evaluate the olivocochlear bundle functioning and speech perception in the presence of noise in females with Polycystic ovary syndrome (PCOS).

Method

Twenty participants in the age range of 18-25 years were included in the study. They were equally divided into two groups: group 1 included females diagnosed with PCOS, and group 2 included healthy adult male participants. Medial olivocochlear (MOC) functioning was evaluated using contralateral suppression of transient otoacoustic emissions (TEOAE). In addition, speech perception in noise was assessed using a quick speech perception in noise test in Malayalam.

Results

Results showed a significant difference for the TEOAE amplitude and signal to noise ratio (SNR) of TEOAEs in quiet and in the presence of contralateral noise and the speech perception in noise between the two groups. Also, no contralateral suppression was noted in the clinical group suggesting that MOC functioning is affected in individuals with PCOS.

Conclusion

It can be concluded that medial olivocochlear bundle functioning and speech perception in noise is affected in individuals with PCOS, which can be attributed to the abnormality in the hormonal status of PCOS.

In this short note, we investigate persistence in two climate risk measures – climate policy uncertainty index (cpu_index) and the Global Land and Ocean Temperature Anomalies (GLOT). Using the fractional integration method, we find that cpu_index and GLOT exhibit high, but mean reverting persistence, both in full and sub-samples.
An Image-Based Rice Weighing Estimation Approach on Clock Type Weighing Scale Using Deep Learning and Geometric Transformations
Authors: An Cong Tran  , Thanh Trinh Thi Kim  , Hai Thanh Nguyen
Published: March 2023

AI impacts surrounding human life, such as the economy, health, education, and agricultural production; however, the crop prices in the harvest season are still on manual calculation, which causes doubts about accuracy. In this study, an image-based approach is proposed to help farmers calculate rice prices more accurately. YOLOv5 is used to detect and extract the scales in the images taken from the harvesting of rice crops. Then, various image processing techniques, such as brightness balance, background removal, etc., are compiled to determine the needle position and number on the extracted scale. Lastly, geometric transformations are proposed to calculate the weight. A real dataset of 709 images is used for the experiment. The proposed method achieves good results in terms of mAP@0.5 at 0.995, mAP@[0.5:0.95] at 0.830 for scale detection, and MAE at 3.7 for weight calculation.
DOPING AMONG MINNOWS IN GHANA: IS ELIGIBILITY THE MAIN ISSUE?
Authors: Adu Nathanael , Aboagye Emmanuel , Addae Stephen Kyenkyehene
Published: March 2023

Despite the use of drugs among amateur athletes linked to inadvertent doping, there is a gap in the literature about other factors that prompted doping behaviour. The present study examined if eligibility to participate in sports competitions is the main cause of doping among young athletes in Ghana. To achieve this, an interpretative qualitative research design approach was adopted. Purposive and snowballing sampling techniques were employed to recruit 10 former basic school student-athletes who admitted to using drugs to participate in school competitions. Semi-structured interviews were the instruments used to collect the data to answer the research questions. Thematic analysis was employed after the data have been transcribed verbatim. The findings of the study revealed that students take performance-enhancing drugs to “become eligible to participate in the competitions”, “to improve stamina”, and “gives them extra energy to perform without getting tired”. Again, it was found that the former student-athletes were unaware of the effects of taking the drugs. The study further exposed some effects of performance-enhancing drugs which included addictiveness and physiological health challenges on the individual. The study recommends that stakeholders should educate minnows on the adverse effects of taking drugs without a doctor’s prescription. Again, age should be used when organising competitions for student-athletes at the basic school level rather than weight, height and facial description.

Published: March 2023

This paper aims to identify the factors that characterize students’ attitudes toward learning social studies. This study employed a quantitative, non-experimental research design utilizing the exploratory factor analysis technique involving 365 junior high school students in secondary school. A researcher-made instrument developed from an in-depth interview with 12 high school students, from a literature review, and related studies have been utilized. To validate the questionnaire, the researcher employs the Content Validity Ratio (CVR) method where ten (10) experts were selected to review the self-made questionnaire. Item statements that pass the threshold of 0.80 were selected as part of the survey questionnaire while those item statements which failed to reach the 0.80 thresholds were eliminated. Utilizing the Exploratory Factor Analysis (EFA), a total of 40 item statements qualified within the threshold of >0.40 after 16 rotations and iterations thus, making them the factors characterizing students’ attitudes toward learning social studies. These measures are the attitude of students in learning different areas under social studies, cognitive attitude, future academic and career planning, positive behavioral attitude, personal attitude, affective attitude, negative behavioral attitude, practical attitude, reflective attitude, and obtaining a degree in social studies.

There was a Time When Board Certification in Pediatric Dentistry Meant Something
Authors: Nathan John E
Published: March 2023

As one reflects on their time on this planet, it’s become apparent that change is inevitable and conceptualization of what was once thought definitive carries new meaning and interpretation. In the political world, while we continually witness diversion and disagreement amongst our elected representatives, we nevertheless once held them in high respect for their competence, commitment to serve and intellect. Today, general discontent and distrust let alone blatant hatred, prevail predicated upon human bias and disrespect for fundamental beliefs in what is fair, ethical, the rule of law and in the best interest of all.
