Quality control of selected cosmetics marketed in libya for traces of toxic heavy metals: urgent need of guidelines harmonization

Heavy metals and trace elements such as lead (Pb), mercury (Hg), cadmium (Cd), arsenic (Ar), nickel (Ni), Chromium (Cr), cobalt (Co), copper (Cu), mercury (Mg), iron (Fe) and aluminum (Al) are detected in various types of herbal cosmetics. Heavy metals and elements can accumulate at high concentrations causing serious risks to human health when consumed. In this study, the levels of potential heavy metals of Pb, Ar, Cd, and Ni were quantitatively determined using atomic absorption spectroscopy. Samples of Henna leaves, Henna paste, Khol stones and baby Talcum powder were collected randomly from different public markets of Tripoli city. The results were evaluated by using different international guidelines, US-FDA, EU regulation, German (BVL), World Health Organization (WHO) and Canadian Guidelines. Because of controversial global guidelines, the study urgent the ultimate need for setting up harmonized minimum levels of heavy metals in cosmetics that could be applicable worldwide. Generally, the presence of a higher concentration of some of the studied heavy metals was observed, and the effect of these heavy metals at higher levels will be more harmful to consumer health after prolonged usage. In conclusion, nationally, the need for developing and updating the national specification for cosmetics by the Libyan National Centre for Standardization and Metrology (LNCSM) to protect consumers from more catastrophic cosmetic hazards is urgently required.

Evaluation model of english teaching effect based on neural network algorithm and support vector machine

Abstract- The role of support vector machine in the evaluation of English teaching effect is very important, but there is a problem of inaccurate evaluation of results. The traditional English teaching mode cannot solve the accuracy and efficiency of the effect evaluation of students' English teaching and cannot meet the requirements of English teaching effect evaluation. Therefore, this paper proposes a neural network algorithm to innovate and optimize the analysis of support vector machines. Firstly, the relevant theories are used to construct a multi-index English teaching effect evaluation system with teachers and students as the main body, and the indicators are divided according to the data requirements of English teaching effect evaluation indicators to reduce the support vector machine in the interfering factor. Then, the neural network algorithm is used to solve the optimal solution of kernel function parameters and regularization parameters of the support vector machine, and the support vector machine scheme is formed, and the support vector machine results are carried out Comprehensive analysis. MATLAB simulation shows that the evaluation accuracy of the English teaching effect of the neural network algorithm and the support vector machine under certain evaluation criteria Optimal, short evaluation time.

Continuing pharmacy education and training in libya

Lifelong learning is becoming part of the philosophy of professional education. Continuing medical education is the responsibility of all personnel who are responsible for the delivery of components of the health care delivery system. Continuing education is becoming increasingly obvious for medical universities, hospitals, and health care providers. Pharmacists who practice in a community pharmacy and hospital, and who are participating in residency recognize that the traditional role of the pharmacist is changing. Over the last decades, a host of new services have been identified as a function of the pharmacist [1]. A review of these services revealed a personal commitment to continuing education. It is the absolute need to develop a level of competence that will improve patient care. In Libya, pharmacists working in the community practice setting are pharmacists with a diploma of pharmacy or with a Bachelor of Pharmaceutical Science, Master of Science, and Doctor of Pharmacy (Pharm D). The main objective is that the graduates possess the knowledge and skills needed to perform optimally to man the pharmaceutical services [1, 2]. Patient's expectations from pharmacists are that the medicine should be effective, safe and affordable. Other expectations from Libyan pharmacists would be to dispense the drugs according to the rules with the right advice on how and when the medicines should be used, and what to do in the case of adverse drug reactions, and the provision of advice on common illnesses. Nevertheless, it is an undeniable fact that the pharmacist has failed to provide all these patient-oriented services [3]. It should be noted that the quality of pharmacy education and training can be improved through certain processes of accreditation.

Comparing machine learning classification models on a loan approval prediction dataset

In the last decade, we have observed the usage of artificial intelligence algorithms and machine learning models in industry, education, healthcare, entertainment, and several other areas. In this paper, we focus on using machine learning algorithms in the loan approval process of financial institutions. First, we briefly review some prior research papers that dealt with loan approval predictions using machine learning models. Next, we analyze the loan approval prediction dataset we downloaded from Kaggle, which was used in this paper to compare several machine learning classification models. During this analysis, we observed that credit scores and loan terms are the attributes that probably most affect the result. Next, we divided the dataset into a training set (80%) and a test set (20%). We trained 27 various machine learning models in MATLAB. Three models were optimized with Bayesian optimization to find the best hyperparameters with minimum error. We used 5-fold cross-validation for the validations to prevent overfitting during the training. In the following step, we used the test set on trained models to measure the models’ accuracy on unseen data. The result showed that the best accuracy both on validation and test data, more than 98%, was reached with neural networks and ensemble classification models.

Improving public hospital efficiency and fiscal space implications: the case of mauritius

Background General Government Health Expenditure (GGHE) in Mauritius accounted for only 10% of General Government Expenditure for the fiscal year 2018. This is less than the pledge taken under the Abuja 2001 Declaration to allocate at least 15% of national budget to the health sector. The latest National Health Accounts also urged for an expansion in the fiscal space for health. As public hospitals in Mauritius absorb 70% of GGHE, maximising returns of hospitals is essential to achieve Universal Health Coverage. More so, as Mauritius is bracing for its worst recession in 40 years in the aftermath of the COVID-19 pandemic public health financing will be heavily impacted. A thorough assessment of hospital efficiency and its implications on effective public health financing and fiscal space creation is, therefore, vital to inform ongoing health reform agenda. Objectives This paper aims to examine the trend in hospital technical efficiency over the period 2001–2017, to measure the elasticity of hospital output to changes in inputs variables and to assess the impact of improved hospital technical efficiency in terms of fiscal space creation. Methods Annual health statistics released by the Ministry of Health and Wellness and national budget of the Ministry of Finance, Economic Planning and Development were the principal sources of data. Applying Stochastic Frontier Analysis, technical efficiency of public regional hospitals was estimated under Cobb–Douglas, Translog and Multi-output distance functions, using STATA 11. Hospital beds, doctors, nurses and non-medical staff were used as input variables. Output variable combined inpatients and outpatients seen at Accident Emergency, Sorted and Unsorted departments. Efficiency scores were used to determine potential efficiency savings and fiscal space creation. Findings Mean technical efficiency scores, using the Cobb Douglas, Translog and Multi-output functions, were estimated at 0.83, 0.84 and 0.89, respectively. Nurses and beds are the most important factors in hospital production, as a 1% increase in the number of beds and nurses, result in an increase in hospital outputs by 0.73 and 0.51%, respectively. If hospitals are to increase their inputs by 1%, their outputs will increase by 1.16%. Hospital output process has an increasing return to scale. With technical efficiencies improving to scores of 0.95 and 1.0 in 2021–2022, potential savings and fiscal space creation at hospital level, would amount to MUR 633 million (US$ 16.2 million) and MUR 1161 million (US$ 29.6 million), respectively. Conclusion Fiscal space creation through full technical efficiency, is estimated to represent 8.9 and 9.2% of GGHE in fiscal year 2021–2022 and 2022–2023, respectively. This will allow without any restrictions the funding of the national response for HIV, vaccine preventable diseases as well as building a resilient health system to mitigate impact of emerging infectious diseases as experienced with COVID-19.

Preferred learning techniques among bachelor’s level students

Learning styles describe how individuals acquire, interpret, and assimilate knowledge differently. The effective use of learning styles is essential for effective classroom education. The three most popular learning styles are kinaesthetic, auditory, and visual. This study pursued to learn more about the preferred learning modes of college students. There were 152 respondents from Baneshwor Multiple Campus, Kathmandu Nepal. The data were collected from first year students of BBS, B.Ed. and BA. The researchers used a scale of learning styles (VAK) with 28 items to accomplish the study's goal, and after confirming its validity and reliability, it was applied to the sample. The results show that there are no statistically significant differences in the types of learning patterns preferred by students. Based on these findings, the study recommends that teachers are encouraged to diversify college teaching strategies and methods to suit the preferred learning styles of their students, particularly new students, in order to motivate them to learn in the college environment and to provide the training needs and requirements necessary to enable them to take individual differences among their students into account when identifying educational goals.

Analysis on digital implementation of sigma-delta adc with passive analog components

Sigma-Delta (SD) analog to digital converters (ADCs) have several advantages over the nyquist rate type ADCs. The linearity over high dynamic range makes the SD ADCs an ideal choice for voice and precise instrumentation applications. The SD-ADC architecture is well established and analyzed [5, 6]. It is heavily based on digital processing and provides a high resolution, low noise output with very low analog implementation effort. The technique of sigma delta ADC is in practice from several decades. The feature of digital dominated design of SD-ADC makes it different from other types of ADCs. As the technologies are evolving, new realization methodologies are emerging for realizing SD-ADC. The conventional approach of realizing an ADC as a separate ASIC and providing the interface to digital IC (either Microprocessor or FPGA) for providing mixed signal processing platform has following limitations.

Removing the stigma and discrimination for people with hiv/aids: the main role of civil society

HIV/AIDS cases in Indonesia continue to increase and have spread to all provinces in Indonesia. Bandung is one of the cities with a high number of people living with HIV/AIDS in Indonesia. As one of the areas with the highest number of reported HIV cases, the Bandung city government seeks prevention and treatment through the role of existing stakeholders. However, stigma and discrimination against people living with HIV & AIDS, now referred to as PLHIV, are still found and are difficult to eliminate. People diagnosed as contaminated with the HIV & AIDS virus often get a negative stigma. This study aims to analyze how to remove the stigma and discrimination of people with HIV/AIDS through the role of civil society. The research results show that stigma against HIV is often directed at certain minority groups and is often associated with morals and religion. Meanwhile, discrimination against people with HIV is manifested in violations of individual rights in the economic, social, and cultural spheres. The issue of stigma and discrimination against PLWHA has not received serious attention. Therefore, the role of civil society is very important because it can open a dialogue with the community regarding HIV/AIDS to dispel myths that tend to discriminate against PLHIV.

Effect of antimicrobial susceptibility testing on treating libyan outpatients with a suspected bacterial infection

Clinical microbiology serves as a partner to clinicians in the diagnosis and treatment of infectious diseases. Antibiotics are prescribed empirically before the availability of antimicrobial susceptibility testing data, especially when the patient's medical status could deteriorate by suspending the treatment. To investigate the impact of antimicrobial susceptibility testing on the management of outpatients with suspected bacterial infection in Libyan patients, a cross-sectional prospective study concluded on microbial microdroplet culture by including outpatients with suspected bacterial infection, who have done antimicrobial susceptibility testing. Thus, 53 Libyan patients with urinary tract infections and 14 Libyan patients with skin infections were included in this study. Before the availability of antimicrobial susceptibility testing data, 25 patients were appropriately treated while 42 patients were inappropriately treated. After the availability of antimicrobial susceptibility testing data, the number of appropriately treated patients increased to 57 patients. Thus, antimicrobial susceptibility testing improved the management of 41 patients by discontinuing an unnecessary antibiotic in four patients, starting necessary antibiotic therapy in 18 patients, and changing to more appropriate antibiotic in 19 patients. However, the antimicrobial susceptibility testing has no impact on the management of 24 patients and has led to the worsening of the management of two patients. The effect of antimicrobial susceptibility testing of antibiotic de-escalation was assessed in 35 patients; however, antibiotic de-escalation occurred in six patients. Thus, data of antimicrobial susceptibility testing has improved the management of Libyan outpatients with bacterial infection but their role in antibiotic de-escalation was slight

Knowledge, attitude and practice of healthcare professionals on dose adjustment of acenocoumarol in algeria

Acenocoumarol is the only oral antivitamin K anticoagulant prescribed and marketed in Algeria for the prevention and treatment of thromboembolic diseases. Nevertheless, the difficulty of handling this drug linked to a narrow therapeutic index and to great inter- and intra- individual variabilities of the response to the treatment poses a major public health issue because of its iatrogenic risk. To improve the management of patients on acenocoumarol and optimize its dosage adjustment and reduce iatrogenic secondary to vitamin K antagonists, our main objective work is to assess the knowledge, attitude and practice of health care professionals regarding this anticoagulant agent. We conducted a multicenter descriptive cross-sectional study from April to May 2021. We interrogated 152 health professionals of all ages, all sexes and all grades from different health departments in Oran City (Algeria) prescribing anticoagulants, through a validated questionnaire made up of 26 questions. Statistical analysis was achieved by SPSS version 20 software. Thus, 59.9% were women with a sex ratio of 0.67, 92.8% knew that acenocoumarol belongs to the antivitamin K class, 45.0% chose INR and PT as follow-up parameters, 36.0% chose INR alone and 78.9% were unaware of acenocoumarol dose adjustment algorithms as well as 82.0% were unaware of the existence of pharmacogenetics testing. 54.0% use the recommendations of the HAS for dosage adjustment of patients on acenocoumarol. 07.9% suggested using pharmacogenetic tests to improve the dosage adjustment of acenocoumarol, 06.6% suggested patient follow-up and 05.9% suggested therapeutic patient education as well as 74.3%, wanted to do training on. Therefore, this study highlighted gaps in the medical practice of physicians in terms of dosage adjustment, pharmacogenetics and its impact on dosage optimization. However, the evaluation of their knowledge was considered unsatisfactory. To overcome this lack of knowledge, it seems necessary to make physicians aware of the contribution of pharmacogenetics of acenocoumarol in Algeria.

Natural and anthropogenic changes threatening the ecological and limnological integrity of lake baringo, kenya: a review

Lakes are characterized by dynamic responses to ecological and limnologic disturbances that occur within a constrained timeframe. Some endorheic lakes in the Kenyan Rift valley are presently regarded as environmental hotspots because of complex changes that are revealed through multiple proxies; changing lake levels and surface area, turbidity and sedimentation, and the proliferation of macrophytes, and loss of aquatic biodiversity. Lake Baringo is characterized by widespread catchment degradation accompanied by high levels of turbidity during erratic and decline of the native fishery based on Oreochromis niloticus baringoensis. A careful analysis implicates potential natural factors such as catchment topography and increasing anthropogenic pressure as the main causes of lake ecosystem degradation. This paper recommends several strategies for restoration of Lake Baringo based on an integrated multi-faceted approach that combines catchment rehabilitation, pollution control, and provision of alternative livelihoods such as agriculture to the riparian communities

Tetra-block: ultrasound femoral, lateral femoral-cutaneous, obturator, and sciatic nerve blocks in lower limb anesthesia: a case series

The gold standard anesthesiologic procedure for urgent femur fracture surgery is Spinal Anesthesia. It is not always feasible because of patients' severe comorbidities and difficulties in optimizing drug therapy in the appropriate time frame such as discontinuation of anticoagulant drugs. The use of four peripheral nerve blocks (tetra-block) can be a winning weapon when all seems lost. We present, in this case series, three Caucasian adult femur fractures (an 83-year-old woman, a 73-year-old man, and a 68-year-old woman) with different and major comorbidities (cardiac or circulatory disorders on anticoagulants therapy that were not discontinued on time; breast cancer and others) underwent the same anesthesiologic approach in the urgent setting. Ultrasound peripheral nerve blocks, that is femoral, lateral femoral cutaneous, obturator, and sciatic with parasacral approach were successfully performed in all patients who underwent intramedullary nailing for intertrochanteric fracture. We evaluated the adequacy of the anesthesia plane, postoperative pain control with the VAS scale, and the incidence of postoperative side effects. Four peripheral nerve blocks (Tetra-block) can be alternative anesthesiologic management in urgent settings, in patients where drug therapy cannot be optimized, as in antiplatelet and anticoagulant therapy.
