Mineralization of the In Ateï gold district (Central Hoggar, South Algeria)
Authors: Boutrika Rabah
Published: October 2023

The In Ateï gold district is located in the eastern part of the Laouni “LATEA” terrane (acronym of Laouni, Azrou-n-Fad, Tefedeset, Egéré-Aleksod) (central Hoggar, southern Algeria). In fact, during the post-collision period of the Pan-African orogeny (600 and 570 Ma), this microcontinent was partly destabilized until it corresponded to a meta-craton.
The In Abeggui gold deposit is part of the In Ateï district and is located 210 km southeast of the town of Tamanrasset. It is located in a large gabbro-diorite massif of the Neoproterozoic volcano-sedimentary series.
The In Abeggui deposit shows two morphological types of gold veins and a mineral paragenesis different from the rest of the Hoggar.
In the In Abeggui deposit, a biotite granite pluton comprising contemporary gabbro-diorite bodies is intrusive in the Neoproterozoic volcano-sedimentary series. The mineralized veins are mainly hosted in one of these mafic bodies. Numerous dykes of mafic and felsic rocks cut both the biotite granite and the gabbro-diorite massif. Felsic dikes include granites, microgranites, pink aplo-pegmatites and aplites.
The main objective of this work is to study the types of gold mineralization expressed in the Laouni terrane (central Hoggar) based more particularly on those of the In Atei region.
Two generations of gold-bearing quartz from the In Abeggui deposit can be distinguished: Veins 1: Tourmaline quartz veins predominantly N30° embedded in the gabbro massif, and Veins 2: Stockwork and quartz veinlets, hosted in aplite dykes covering the vein system1

Authors: La Spina Vincenzina , Navarro-Moreno David , Martínez Gil Joaquín
Published: October 2023

La ejecución de cubiertas planas de tierra ha sido una técnica frecuente en el Mediterráneo. El Campo de Cartagena no queda ajeno a esta práctica, empleándose una tierra local conocida como láguena. Aunque las cubiertas planas de tierra han sido objeto de diversos estudios, ninguno ha abordado de forma conjunta y monográfica sus características materiales y constructivas en esta comarca. El objetivo del artículo es identificar sus particularidades, tanto materiales, mediante la caracterización química y mineralógica de la láguena, como técnicas, a partir de las soluciones constructivas identificadas. La metodología seguida se fundamenta en una investigación histórica, una toma de datos in situ y un estudio de laboratorio. Los resultados confirman que la láguena procede de la meteorización de la filita, atribuyendo su coloración violácea al óxido férrico. Además, corroboran su empleo desde la Antigüedad hasta el s.XX y han permitido establecer similitudes constructivas con otras zonas del ámbito español.
Indoor air quality in naturally ventilated dwellings in Spain
Authors: Garcia-Ortega Sonia , Linares-Alemparte Pilar
Published: October 2023

This article presents the results of the exploratory study on indoor air quality in existing dwellings with traditional ventilation systems based on natural ventilation. A preliminary study of the most representative typology of the Spanish housing stock has been conducted and, based on it, twelve dwellings located in Madrid have been monitored in different periods. Monitored indoor air quality has been compared to that required in the regulations in Spain, the Código Técnico de la Edificación (Technical Building Code). According to the results of the research, 50 % of the monitored dwellings do not comply with the CO2-based air quality quantification offset in the regulations. Such non-compliance is primarily caused by high CO2 concentrations in winter, especially in bedrooms. These high concentrations and their seasonality are attributed to the interference of the occupant’s behaviour, influenced by weather conditions, that is affecting the efficiency of the existing natural ventilation systems.
COVID-19 and Social and Health Inequalities in Italy: A Syndemic Approach
Authors: Giarelli Guido
Published: October 2023

The article begins by introducing three questions that make the Italian case of health inequalities during the COVID-19 pandemic particularly interesting and goes on to discuss the problem of an appropriate and valid model to analyse the outbreak, defining it as a “syndemic” and not simply a pandemic. Given the unsatisfactory heuristic value of the current, most common models of social determinants of health inequalities in terms of the syndemic approach, a new non-linear circular causal model is proposed. Its application to the case of Italy to analyse the COVID-19 syndemic outcomes in terms of exposure, susceptibility, access to healthcare, and quality of life is then presented and discussed in detail. The conclusions reached highlight how the responses to the three initial questions confirm the validity of the application of the model proposed and the possible utilization of the results obtained for policy action.
O vírus não escolhe grupos sociais? – Impactos da COVID-19 nas desigualdades sociais
Authors: Tavares David
Published: October 2023

O presente artigo evidencia o impacto da COVID-19 nas desigualdades sociais em Portugal, com base no conhecimento produzido pela sociologia e ciências sociais em geral sobre a realidade portuguesa, cruzando e complementando esta informação com a de outros países e regiões do mundo. Os diferentes contributos demonstram que a mortalidade e morbilidade causadas pela pandemia são maiores entre os grupos sociais mais vulneráveis e que as consequências sociais da COVID-19 se consubstanciam no agravamento das desigualdades sociais, em termos de rendimento, escolaridade, vínculo laboral, pertença étnico-racial, género e local de residência. Todas estas dimensões se cruzam, acumulam e adicionam, produzindo diversos tipos de discriminações. O impacto da pandemia nas desigualdades sociais não se reporta, portanto, ao campo estrito da saúde, mas alarga-se a um horizonte mais amplo e multidimensional.

Published: October 2023

Uropathogenic Escherichia coli (UPEC) is a nosocomial pathogen associated with urinary tract infections and biofilm formation, which contributes to antibiotic resistance. Discovering potent antibacterial agents is crucial. This study aimed to assess the antibacterial and antibiofilm effects of gold and silver nanoparticles on UPEC using Scanning Electron Microscopy (SEM). UPEC biofilms were cultivated on nitrocellulose membranes for 48 hours at 37°C, then treated with gold nanoparticles (50 ppm and 100 ppm) and silver nanoparticles (50 ppm and 100 ppm) for another 48 hours. Antibacterial and antibiofilm activities were evaluated through cell density and SEM analysis. SEM revealed lower cell density, reduced biofilm formation, and altered cell morphology with rough, wrinkled surfaces after nanoparticle treatment. In conclusion, gold and silver nanoparticles exhibit antibacterial and antibiofilm properties, as observed in SEM analysis. SEM is a valuable tool for studying the antimicrobial effects of nano gold and silver on bacterial cell morphology and biofilm populations.

Published: October 2023

Introduction The case study teaching method is important in imparting critical thinking and clinical reasoning skills in nursing students. The self-efficacy of the nurse educators towards the use of the case study teaching method is a critical aspect of determining the quality of teaching using this method. This study, therefore, aimed at assessing the self-efficacy of the nurse educators towards the use of the case study teaching method in Malawi. MethodA cross-sectional study utilizing a quantitative research design was conducted at eight nursing colleges that are under the Christian Health Association of Malawi. Only nursing colleges offering college diplomas in nursing and midwifery technician were involved. A total of 145 nurse educators completed the Self-Efficacy towards Teaching Inventory. The computer software of Statistical Package for Social Sciences version 23.0 was used to analyze the data.Results The results show that the nurse educators are confident in using the case study teaching method (mean=78.4, SD=11.166). The study results also show that there are differences in mean scores between the nurse educators who attended an education workshop and those who did not (t=5.2334; P<0.001). Conclusion The study indicates that Malawian nurse educators have moderate levels of self-efficacy in using the case study teaching method. This study, therefore, has shown a need for nurse educators to participate in strategies that can increase their level of self-efficacy in using case studies.

Published: October 2023

The space industry has grown significantly in importance, with more and more private companies aiming to provide services within the space environment. These include space tourism and the extensive deployment of satellites for earth monitoring, communication, and space exploration. Technological developments have accelerated the ability of private companies to provide services and establish businesses in the space area, with several new businesses providing services worldwide. With the technological advances in AI, the space area has been an essential area for AI to be deployed and the challenges it may face. The challenges with AI in the space sector and regulations in the space sector overall is the global regulatory nature of the environment. This is incredibly challenging given the significant discussion regarding national AI regulations to deal with this fast-developing area. Based on the challenging regulatory environment and associated risks, financing these new business models has presented new complexities that must be taken care of. Asset-based financing of such operations represents vital opportunities to deal with the intricate complexities of such operations and the various legal environments. While liability and other challenges have to be considered both in light of national and international regulations that may have to be taken into account, asset financing represents a very attractive option given the priority and security of the interest in the space asset. Specifically, there are various remedies given that it reduces the risk of various non-compatible regulations in order to secure their concerning asset rights. Furthermore, pre-existing third-party interests can be looked up via online registries, reducing potential risks.

On the Need for Empirical Research in Pedagogy: Some Reflections and Theoretical and Methodological Demands:
The purpose of this article is to describe and evaluate theoretical and methodological approaches in designed empirical research in pedagogy. We point out that pedagogy and with it educational research are crucial to the overall development of various fields of study and learning as a whole. They are important because they seek to describe, understand and explain how learning takes place throughout a person’s life and how the formal and informal contexts of education affect all forms of learning at different levels (from micro to macro) of understanding educational processes. Educational research should therefore become a priority, as it plays an important role for understanding the processes of upbringing, teaching, learning, educating, etc., and their theoretical and conceptual definition and reliability testing within the framework of adequate curricula for the individual and society and the formulation of educational policy. So that pedagogical sciences guarantee the highest quality of upbringing and education in the country and can develop at the height of the international educational research. Therefore, attention should be paid to the aspects that will allow pedagogy and educational research to obtain the appropriate appropriate status in the field of domestic social sciences and humanities and, as a result, their internationalization.

Authors: Azmi Yantri Ulul , Setyowati Lilis
Published: October 2023

This research aims to analyze the influence of financial performance on company value in banking sub-sector companies listed on the Indonesia Stock Exchange (IDX) for the 2018-2021 period. The data used is secondary data in quantitative form in the form of annual financial reports. The sampling method used purposive sampling, which resulted in a sample of 43 companies. The analytical method used is multiple linear regression analysis. Company size is proxied by SIZE, liquidity is proxied by a loan-to-asset ratio (LAR), profitability is proxied by operating costs and operating income (OCOI), and leverage is proxied by capital adequacy ratio (CAR) as an independent variable, company value is measured using price-to-book value (PBV) as the dependent variable. The results of this research show that company size does not have a significant effect on company value. In contrast, loan-to-asset ratio (LAR), operational costs and operating income (OCOI), and capital adequacy ratio (CAR) positively and significantly affect company value. This research provides practical implications that company value can be used as a measure of the success of company management in future operational prospects to create trust for company shareholders.

Authors: Qoda'ah Gn , Abdurrahman Abdurrahman
Published: October 2023

This research aims to prove the influence of financial performance on company value, which is mediated by Islamic performance. The method used is panel data regression and path analysis using secondary data from Islamic commercial bank's (ICBs) annual reports in Indonesia. The population in this research is ICBs in Indonesia registered with the Financial Services Authority (FSA) in 2017-2021, totaling 14 ICBs. The sampling technique uses purposive sampling to obtain a sample of 10 ICBs. The research results prove that return on assets (ROA) and capital adequacy ratio (CAR) partially have a positive effect on the sharia maqashid index (SMI). Operational cost operational income (OCOI) partially does not affect SMI and firm value. CAR and SMI partially have a positive effect on firm value. ROA partially does not affect firm value. SMI can mediate the influence of ROA and CAR on firm value, but SMI cannot mediate the influence of OCOI on firm value. This research can complement existing theories and be a reference for Islamic banking in improving the implementation of SMI indicators and for the government in designing Islamic banking performance measurement models integrated with SMI indicators.

This research is a type of case study research with a qualitative approach. The data sources used are primary and secondary. Data collection techniques use interviews, observation, and literature. The results of the research show that the implementation of Islamic marketers includes Theistic (rabbaniyyah) implemented because the appearance of Islamic marketers is closed, covering the private parts and wearing the hijab; Ethical (akhlaqiah) implementation always behaves well, speaks politely, and not differentiate between one customer and another; Realistic (waqiyyah), namely the officer is honest in offering the product and does not exaggerate the product's advantages; Humanism (insaniyyah) implemented because officers always respect customers who come and are friendly regardless of ethnicity, religion, and race. The results of this research can be a reference for Islamic banking or other Islamic financial institutions to implement Islamic marketers in marketing products to the public.
A Systematic Literature Review Of Religiosity On Customers' Decisions In Choosing Islamic Bank
Authors: Chusniah Dita Nur Amaliatul , Samsuri Andriani
Published: October 2023

This research aims to identify the influence of religiosity in determining customers' decisions to choose an Islamic bank using a systematic literature review (SLR) approach. The SLR stages start from identifying, assessing, and interpreting literature, resulting in 18 articles in 18 journals published in 2015-2022, indexed by SINTA, and having E-ISSN. The results of this research indicate that the influence of customer religiosity still has opportunities and challenges to be improved, as indicated by the low religiosity factors of each customer, such as the lack of religious calling that underlies attitudes and behavior, the basis for prohibiting usury and use limited to profit interests. The indicators of religiosity used to influence customers' decisions to choose an Islamic bank are the quality of Islamic products, avoiding riba transactions, the principle of profit sharing, and Islamic features. The research in the sample has a gap in results so it can become a gap for further research. The research proposals obtained in improving customer decisions are increasing religiosity, meeting customer needs, and the effectiveness of Islamic financial literacy. This research can be used as a reference for further research regarding the role of religiosity in influencing customers' decisions to choose Islamic banks.

Published: October 2023

The sciatic nerve damage can cause symptoms such as loss of muscle strength and pain as a result of trauma to the nerve due to pressure, stretching or cutting, as well as lifelong disability. Despite the increasing knowledge about sciatic nerve regeneration mechanisms, full functional recovery is still insufficient. It is well known that exercise improves overall health. The current study aimed to reveal the therapeutic effects of swimming exercises using electrophysiological methods in rats with experimental sciatic nerve injury. Eighteen male Wistar Albino rats were used in this study. The subjects were randomly divided into three groups (n=6): 1-Control (C), 2-Intact Exercise (IntE), 3-Operated Exercise (OpE) groups. Sciatic nerve injury was performed by inducing experimental damage to the left hind extremity sciatic nerve of rats. Swimming exercise was applied for 45 minutes a day, five days a week (25°C) for four weeks. The level of regeneration was evaluated by taking motor function test-sciatic function index and EMG recording performed at the beginning of the experiment (day 0), after nerve damage (day 3), and at the end of the experiment (day 35). It was determined that sciatic function index, amplitude of motor and sensory nerves, peak-peak amplitude, percentage of compound muscle action potential, motor and sensory nerve conduction velocities, which decreased after sciatic nerve injury, increased with swimming exercise (p

Multimodal Antiemetic Therapy and Emetic Risk Profiling
Authors: Ho KY , Chiu JW
Published: October 2023

Introduction: Postoperative nausea and vomiting (PONV) is a common problem with no simple solution. This review highlights factors that are known to increase the risk of PONV. It examines the various data on pharmacological and non-pharmacological methods that have been used to prevent PONV. Methods: Peer-reviewed journals on the subject were covered. Conclusion: Patient, surgical and anaesthetic factors increase the risk of PONV. While patient and surgical factors are understandably difficult to control, a multimodal approach involving both pharmacological and non-pharmacological interventions has been successfully adopted to reduce the incidence of PONV. Various factors have been identified to categorise patients into different profiles to determine their risk of PONV. Perioperative strategies can then be targeted at these patient groups.

Published: October 2023

A key factor in the tissue engineering approach to tissue repair and regeneration is the use of appropriate cells. Mesenchymal stem cells (MSCs) are derived from bone marrow stroma or connective tissues and they have the potential to differentiate into various mesenchymal cell lines in vitro and in vivo. These cells hold great promise for musculoskeletal tissue engineering. This review is based mainly on the work which has been done in the National University of Singapore on the use of MSCs for engineering cartilage, growth plate, bone and tendon/ligament as well as the clinical trail of autologous chondrocyte implantation. It can help to shape future research on musculoskeletal tissue engineering.
Laparoscopic-assisted Colon and Rectal Surgery – Lessons Learnt from Early Experience
Authors: Koh DCS , Wong KS , Sim R , Ng YP , Hu ZQ , Cheong DMO , Foo A
Published: October 2023

Introduction: Current evidence shows that laparoscopic bowel surgery is associated with a lower incidence of postoperative ileus, lower postoperative pulmonary and wound complication rates, shorter hospital stays and a quicker return to activity than open surgery. This paper aims to report our early experience with laparoscopic-assisted colorectal procedures in our Centre for Advanced Laparoscopic Surgery and the important lessons we have learnt from this. Materials and Methods: All laparoscopic-assisted colon and rectal surgical (LAC) procedures performed between January 2000 and December 2003 were reviewed. Clinical and operative records of these patients were reviewed. Data retrieved included patient demographics, selected intra-operative parameters, and postoperative outcomes. In order to provide a comparable reference, an equal number of matched open procedures over the same period were accrued and similarly analysed. All patients were managed on a standard carepath. All data were entered into a database and analysed using a statistical software package. Results: Forty-two laparoscopic-assisted colorectal procedures were performed from June 2000 to December 2003. A similar number of diagnosis-matched patients with open colorectal procedures were used as comparison. The diagnoses included cancer (68.5% versus 73.8%), diverticulosis (5.7% versus 9.5%) and polyps (14.3% versus 9.5%). Seven were converted to open surgery because of bleeding, adhesions and locally advanced disease. Laparoscopic-assisted procedures performed included 1 right hemicolectomy, 5 left hemicolectomies, 9 anterior resections, 1 abdominal-perineal resection, 3 sigmoid colectomies, 11 colostomies and 1 Hartmann’s procedure. Mean perioperative time (146 min versus 125 min, P = 0.173) was comparatively longer. Mean duration for analgesic requirement (2.25 days versus 2.64 days, P = 0.05), mean length of stay (5.31 days versus 9.07 days, P <0.05), mean time to commencement of diet (2.91 days versus 4.05 days, P <0.001) and mean time to first bowel movement (2.57 days versus 4.10 days, P <0.001) were all comparatively shorter. General morbidity rates (17.1% versus 21.4%, P = 0.35) were lower. No local wound complications were found in our laparoscopic-assisted group. Patients who had undergone open surgery instead of the planned laparoscopic-assisted procedures fared more poorly. Conclusions: Laparoscopic-assisted colorectal procedures performed in well-selected patients are associated with shorter hospital stays, quicker return of bowel function and lower morbidity when compared to the matched open procedures. Early experience should be acquired from performing technically simple procedures in patients with benign conditions before progressing to definitive resections in those with cancer.

Authors: See HT , Cheung YB , Yong F , Khoo KS , Ang P
Published: October 2023

Introduction: In addition to surveillance practices, chemoprevention and prophylactic surgery can reduce the risk of cancer in individuals at high risk. Sociocultural factors may have a role to play in such decision making. Little is known regarding the factors that play a role in decision making in Singapore. Materials and Methods: One hundred and two individuals at normal risk completed a questionnaire on the concept of chemoprevention and prophylactic surgery. The results were analysed using the convenience sampling method. Results: Participants were mostly Chinese (94.1%). More than 90% of the respondents answered the section on prophylactic surgery and chemoprevention. Thirty-eight individuals (41.3%) would not consider prophylactic surgery, while 42 (45.7%) would not consider prophylactic surgery now but might consider it in the future. Twenty-five individuals (26.9%) would not consider chemoprevention by taking a medication, 57% would not consider it now but might in the future. Conclusion: A cross-sectional public view suggests that medical prophylaxis is likely to be more acceptable to the general public compared to surgical prophylaxis.
Diffuse Idiopathic Skeletal Hyperostosis with Cervical Spinal Cord Injury – A Report of 3 Cases and a Literature Review
Authors: Sreedharan S , Li YH
Published: October 2023

Introduction: Diffuse idiopathic skeletal hyperostosis (DISH), though common, is often asymptomatic. However, spinal hyperostosis can predispose the affected to chronic myelopathic symptoms and acute spinal cord injury. Clinical Picture: We report on 3 patients with DISH, who sustained traumatic cervical cord injuries. Two were tetraplegic at presentation. The radiologic findings of the patients are also discussed. Treatment: Both the tetraplegic patients were treated non-surgically in view of high surgical risk. Outcome: Both the tetraplegic patients died due to mechanical respiratory failure. Conclusions: The potential catastrophic neurological sequelae of DISH from relatively minor trauma must be understood. Further studies are needed to aid in evidence-based clinical management of asymptomatic patients with DISH.
Endovascular and Surgical Management of Vertebral Artery Dissecting Aneurysms Presenting With Subarachnoid Haemorrhage: Medium-term Experience
Authors: Sheah K , Lim W , Chan Chumpon
Published: October 2023

Introduction: Dissecting aneurysms of the vertebral artery are associated with a high incidence of rebleeding and mortality if untreated. Current endovascular alternatives to surgery are being evaluated. Materials and Methods: We conducted a retrospective review of our experience with endovascular as well as surgical treatments of dissecting vertebral artery aneurysms in 6 patients. Three patients were treated with a combination of coils in the proximal artery and aneurysm sac; 1 with a combination of coils and balloon; and 2 with aneurysm clipping surgery. All patients were treated with the primary intention of coil deposition within the aneurysm sac and proximal vertebral artery. No proximal flow arrest was used. Anticoagulation was given during and after the procedure. Results: Technical success was achieved in all patients, and there was no post-procedural neurological deficit. Follow-up for a mean of 40 months (range, 7 to 64) confirmed the clinical stability of symptoms, as well as the cessation of flow to the aneurysm. Conclusions: Endovascular treatment of vertebral artery dissections is a viable alternative to surgery in the appropriate setting. It has the benefit of being minimally invasive, allowing concomitant balloon testing as well as retaining the option to convert to surgery.

Authors: Pant R , Poh ACC , Hwang SG
Published: October 2023

Introduction: Intramuscular lipomas of the pectoralis major muscle are rare and may mimic malignant breast tumours. Clinical Picture: A 58-year-old Chinese woman presented with a 2- year history of an enlarging left breast mass. Clinical examination revealed a palpable hard mass in the left breast. Treatment: Standard mammographic views revealed a radiolucent mass deep in the left pectoralis major muscle. The mass was homogeneously hypoechoic with smooth margins on ultrasound. Outcome: Surgical excision of the mass was performed. Histological diagnosis was an intramuscular lipoma of the left pectoralis major muscle. Conclusions: Recognition of the radiolucent density and submammary location of a pectoralis major muscle lipoma is important as it allows the correct diagnosis to be made.

The Prevention of Neuroma Formation by Diathermy: An Experimental Study in the Rat Common Peroneal Nerve
Authors: Tay SC , Teoh LC , Yong FC , Tan SH
Published: October 2023

Introduction: There have been anecdotal reports of the efficacy of diathermy (electrocoagulation) in the prevention of neuroma formation. However, this has not been investigated in the laboratory. In this experiment involving 40 rats, diathermy was applied to the terminal proximal ends of transected rat common peroneal nerves to evaluate its effect on neuroma formation. Materials and Methods: Monopolar and bipolar diathermy set at 45 W, applied for different durations (4 seconds and 10 seconds), were evaluated. Under histological control, the presence of neuroma formation and the diameter of the nerve ends were evaluated at 3 months. The contralateral common peroneal nerve in the same rat served as the control. The dorsal root ganglia of 2 rats in each group were also harvested for histological study. Results: The incidence of neuroma formation was 30% in the group which received high-duration monopolar diathermy (10-second application), versus 90% in the control group (P <0.05). The mean diameter of the nerve ends was smaller at 0.51 mm [standard deviation (SD), 0.29] versus 0.85 mm (SD, 0.24) in the control (P <0.05). The incidence of neuroma formation was 30% in the group which received low-duration monopolar diathermy (4-second application), and 83% in the control group (P <0.05). The diameter was 0.43 mm (SD, 0.14) versus 0.85 mm (SD, 0.28) (P <0.05). High-duration bipolar diathermy applied for 10 seconds, showed a neuroma formation of 25% versus 100% in the control group (P <0.05). The diameter of the nerve ends was 0.48 mm (SD, 0.07) versus 0.79 mm (SD, 0.36) in the control group (P <0.05). The incidence of neuroma formation was 60% in the low-duration bipolar group, which received bipolar diathermy application for 4 seconds, and 90% in the control group (P = 0.25). The diameter of the nerve ends in the low-duration bipolar group was 0.52 mm (SD, 0.24) versus 0.76 mm (SD, 0.40). The incidence of neuroma formation and the difference in diameter in the low duration-bipolar group were both not statistically significant. Conclusion: This study demonstrates the effectiveness of monopolar diathermy in reducing the rate of neuroma formation. For bipolar diathermy, an application of 10 seconds was effective in reducing neuroma formation but an application of 4 seconds was not associated with a significant reduction in neuroma formation.

Introduction: Epidemiological data on latex sensitisation among Asian healthcare workers is lacking. The aim of the study is to determine the rate of latex sensitisation in our healthcare workers. Materials and Methods: We recruited 313 healthcare workers, of which 46.6% were operating theatre staff and 53.4% were non-operating theatre staff. Seventy-one administrative staff served as controls. All participants answered a self-administered questionnaire relating to latex exposure and glove-related symptoms. Latex sensitisation was determined by skin prick testing to latex and latex-specific IgE detection. Results: The prevalence of latex sensitisation among healthcare workers was 9.6%, with no difference between operating theatre and non-operating theatre staff. Glove-related symptoms were reported in 13.7% of all healthcare workers, of which 22.9% were sensitised to latex. Only 26.7% of latex-sensitised healthcare workers had glove-related symptoms while the rest were asymptomatic. The most common symptoms were itch and hand eczema but the most important discriminating symptom was contact urticaria. Personal history of atopy was more common in sensitised healthcare workers (40.0%) compared to non-sensitised workers (31.8%). Only 1 out of 9 (11.2%) symptomatic latex-sensitised subjects had sought previous medical attention for the problem. Conclusions: Latex sensitisation among healthcare workers in Singapore should be considered a significant occupational health risk, as it is in the West. Increased screening and awareness of this problem is essential to identify those at risk.

Supervision of students is carried out together with educators and parents because the learning process can reduce juvenile delinquency, including drug abuse and the spread of HIV/AIDS, so with the educational process, some students who have the potential to behave positively will become examples, icons or ambassadors for each other, in school. This research analyzes risk factors for HIV/AIDS transmission in adolescents based on knowledge, attitude, gender, and socio-economic status. The type of research used is observational research with a Cross-Sectional Study design. This type of research is based on collecting and analyzing data in numerical form, namely quantitative research with a sample size of 187 teenage students at SMA Negeri 1 Limboto, Gorontalo Regency, consisting of class 10, class 11th, and 12th grades. Research results show that there is a relationship between knowledge and risk behavior for HIV/AIDS transmission in adolescents (p-value 0.025 < 0.05), there is a relationship between attitude and risk behavior for HIV/AIDS transmission in adolescents (p-value 0.036 < 0, 05), there is a relationship between religious adherence and risk behavior for HIV/AIDS transmission in adolescents (p-value 0.013 < 0.05). The research conclusion is that knowledge, attitudes, and religious observance are related to the risk of HIV/AIDS transmission based on the Plan Behavior theory in adolescents.

Infection control refers to a specific procedure that the hospital follows in order to ensure that the medical staff and the patients are not exposed to any kind of infection. Even though there are different procedures that the hospitals follow, the working staff as well as their patients are still exposed to different diseases. However, hospital settings must have the ideal conditions to prevent infection. Therefore, the purpose of this research is to improve the infection control systems and procedures in Saudi hospitals and to ensure that every person in the hospital is fully safe from any infection that may occur. A questionnaire was created to determine whether the infection control procedures are being used effectively and accurately in Saudi hospitals. Depending on the results of the questionnaire, infection can be reduced if any medical institution followed and improved the infection control procedures.
Microbial bioremediation: Effective Strategy for Removal of Pollutants from Contaminated Industrial Water of Textile Mills Plants. An Overview

Bioremediation is a process used to treat contaminated water by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants. Microbial bioremediation uses microorganisms to break down contaminants by using them as a food source. These toxic compounds are metabolized by enzymes of microorganisms. The industrial water contaminated by heavy metals and other pollutants are common throughout the world. Many strategies are developed to encourage the degradation of pollutants from such affected sites. Bioremediation as one feasible way to be used. It is a technology that employs living microorganisms such as bacteria and fungi to remove harmful contaminants from the polluted environment. The basis of bioremediation is that microorganisms remove substances from the environment to carry out their growth and metabolism. The microorganisms used in this strategy can be both indigenous and non-indigenous. These microorganisms take part in the degradation, immobilization, and detoxification of various harmful chemical wastes and contaminants. Microorganisms which perform the function of bioremediation are known as bio-remediators or bio-reformers. The treatment of contaminated water by the conventional method is found to be unfeasible due to its high cost and generates secondary pollutants. Therefore, bioremediation is not effective only for the degradation of pollutants but it can also be used to clean unwanted substances in industrial water and raw materials form industrial waste through the biological activities of microorganisms. Microbial growth depends on several environmental factors such as pH, temperature, and nutrients. The practice bio-stimulation that involves the addition of nutrients to the contamination site enhances the growth of microbes that assist in bioremediation. One of the main nutrients is molasses, in Iraq we used a natural material (dates extracts) in bioremediation of industrial water of textile mills plants.
