The purpose of this study was to assess the knowledge of head and neck cancers (HNCs), their risk factors, signs and symptoms among the general public of Karachi, Pakistan.

Initially, 503 individuals were approached for data collection, out of which 404 fit the inclusion criteria (response rate = 80.03%). Nonprobability convenience sampling was utilized to select participants who fell under the age group of 15–60 years, barring the fields of Bachelor of Medicine and Bachelors of Surgery (MBBS) and Bachelors of Dentistry (BDS). Knowledge was evaluated by a 9-item questionnaire, the scores of which yielded the following interpretations: No (0), low (1–3), moderate (4–6) and high (7–9) knowledge.

Of the 404 participants who completed the questionnaire, 357 (88.4%) participants claimed to be aware of HNC. The HNC knowledge scores had a statistical relevance with socioeconomic status (p = <0.01) and level of education (p = 0.02). Most participants recognized a “lump or swelling in the throat” (87.1%) as the most common symptom, followed by “bleeding in mouth or throat” (84.7%). Surprisingly, 75.25% of participants thought HNCs were inclusive of brain cancer.

Overall, knowledge of HNCs among the general public of Karachi surpasses the knowledge in other regions around the world. Our study demonstrated that people indulge in unhealthy habits despite having sufficient knowledge and this warrants prompt interventions and counseling of the people.

Despite the crucial role that healthcare practitioners (HCPs) have in preventing and detecting oral cancer (OC), studies suggest that dentists and physicians do not adequately detect early stage OC which is attributed to their attitude and knowledge. This Saudi Arabian study aims to assess HCP's knowledge and practice vis‐à‐vis OC's risk factors and patient evaluation.

A questionnaire was distributed to HCPs in six different Saudi Arabian settings. A total of 16 items representing a mixture of OC's risk and non‐risk factors were measured.

The study found that only 20.9 percent of HCPs could distinguish 11 items or more correctly. Additionally, when HCPs obtained the patient's medical history, no more than 32.3 percent routinely assessed ten important OC issues. Almost 36 percent of HCPs thought that attending to too many patients prevented them from taking proper medical histories, and 37.6 percent admitted that more training in preventing and detecting OC is needed.

Since there is no effective automated system to reach Saudi Arabian practitioners, the number of practitioners involved in this study is limited.

The knowledge and practice of HCPs with relation to OC do not appear to be sufficient and HCPs should have better and more training in OC prevention and early detection.

It appears that Saudi Arabian HCPs do not adequately participate in OC's prevention and early detection. It is suggested that continuous education strategies in Saudi Arabia should be reassessed and emphasis given to OC diagnosis.

Healthcare practitioners (HCPs) have a major responsibility in the prevention and early detection of oral cancer (OC). Accordingly, adequate training in this area will positively enhance healthcare practitioners' accountability towards their patients. The present study was conducted in Saudi Arabia with the objective of assessing HCPs' opinion vis‐à‐vis OC prevention and early detection.

A cross‐sectional survey was distributed among HCPs in six different settings in Saudi Arabia.

Totals of 41.2 per cent and 63.4 per cent of HCPs thought that they are adequately trained to perform an OC examination and to palpate the lymph nodes, respectively. Similarly, 33.2 per cent and 25.8 per cent thought that they are adequately trained to provide tobacco and alcohol cessation education for their patients, respectively. Of HCPs, 45.1 per cent thought they had a low level of knowledge and training in OC prevention and the early detection thereof, 53.6 per cent agreed that their knowledge about OC was not current, and 82 per cent were comfortable with referring suspicious lesions to specialists.

It appears that the current knowledge and training in OC prevention and early detection among HCPs in Saudi Arabia is not up to the desired level. Accordingly, it is suggested that OC prevention and early detection should be given the necessary attention when establishing new continuous education strategies in Saudi Arabia.

This review deals with the pros and cons of ultraviolet (UV) radiation on human beings and the role of textile clothing and the chemicals used for textiles to protect from their harmful effects.

UV radiation (UVR) which has further divided into UVA, UVB, and UVC. Almost 100% of UVC and major portion of UVB are bounced back to stratosphere by ozone layer while UVA enters the earth atmosphere. Excessive exposure of solar or artificial UVR exhibit potential risks to human health. UVR is a major carcinogen and excessive exposure of solar radiation in sunlight can cause cancer in the lip, skin squamous cell, basal cell and cutaneous melanoma, particularly in people with the fair skin.

This article aims to provide a comprehensive overview of the harmful effects of UVR on human skin, factors affecting UV irradiance and factors affecting UV protection offered by textile clothing.

Effect of fiber properties, yarn properties, fabric construction, fabric treatments and laundering has been reviewed along with the identification of gaps in the reported research. A comparison of inorganic and organic UV absorbers has also been given along with different testing and evaluation methods for UV protective clothing.

The goal was to improve the quality of the hospitalization process and the management of patients, allowing the reduction of costs and the minimization of the preoperative Length of Hospital Stay (LOS).

The methodology used to improve the quality of the hospitalization process and patient management was Lean Thinking. Therefore, the Lean tools (Value stream map and Ishikawa diagram) were used to identify waste and inefficiencies, improving the process with the implementation of corrective actions. The data was collected through personal observations, patient interviews, brainstorming and from printed medical records of 151 patients undergoing oral cancer surgery in the period from 2006 to 2018.

The authors identified, through Value Stream Map, waste and inefficiencies during preoperative activities, consequently influencing preoperative LOS, considered the best performance indicator. The main causes were identified through the Ishikawa diagram, allowing reflection on possible solutions. The main corrective action was the introduction of the pre-hospitalization service. A comparative statistical analysis showed the significance of the solutions implemented. The average preoperative LOS decreased from 4.90 to 3.80 days (−22.40%) with a p-value of 0.001.

The methodology allowed to highlight the improvement of the patient hospitalization process with the introduction of the pre-hospitalization service. Therefore, by adopting the culture of continuous improvement, the flow of hospitalization was redrawn. The benefits of the solutions implemented are addressed to the patient in terms of lower LOS and greater service satisfaction and to the hospital for lower patient management costs and improved process quality. This article will be useful for those who need examples on how to apply Lean tools in healthcare.

“Healthy public policy” in tobacco control is essential to support other efforts to reduce smoking prevalence, especially among the young. The government of Guernsey in the Channel Islands has recently agreed to implement a comprehensive and integrated package of measures intended to make tobacco smoking less acceptable, less accessible and less affordable to young people. Such measures include raising the legal age of purchase, a substantial price rise over a period of years, a total ban on local tobacco advertising and specially funded initiatives in health education and promotion. Summarizes the process and barriers to achieving “Healthy public policy” in tobacco control.

In writing a paper to honour Professor Clem Tisdell, it is apt to focus attention on the environmental and human costs of commercial agricultural production, especially the Green Revolution technology in South Asia during the last few decades. This is an area where Professor Tisdell has done much research, amongst the multitude of other research interests he has pursued in his very illustrious career. Modern commercial agricultural practices involving chemical inputs such as fertilizers and pesticides have been associated with huge increases in food production never witnessed before and, in the case of cereal production (especially wheat) under Green Revolution technology, recorded spectacular growth. As statistics show, production and productivity have increased. However, the high chemical usage of fertilizers and pesticides to bring about these spectacular increases in food production is not without its problems. A visible parallel correlation between higher productivity, high chemical input use and environmental degradation and human health effects is evident in many countries where commercial agriculture is widespread. This paper discusses the environmental and health effects/costs arising from the high use of chemical inputs to increase production and productivity in South Asia, with a field study carried out in Sri Lanka to show the health costs arising from direct exposure to pesticides during pesticide handling and spraying on farms by small‐scale farmers.

The purpose of this paper is to explore the perceived responsibilities of five not‐for‐profit hospitals in Bangalore, India, towards society.

The method used is qualitative design with some quantitative elements. Data were collected through a survey of 79 physicians and 104 managers and other stakeholders of the hospitals.

The analysis reveals the existence of highly significant differences in the perception about workplace responsibilities between the doctors and other stakeholders. It also highlights the importance of top management involvement with various stakeholders in effectively carrying out the overall social responsibilities of the hospitals. It was found that the hospitals must take into account the social, cultural and financial characteristics of the patients while fulfilling societal obligations. Training needs, environmental impact audit and encouragement for employees to join local voluntary organizations are the immediate needs for improving the CSR activities of the hospitals.

The study had a small sample and referred only to the perceptions of physicians/management personnel. Further studies should be done with larger samples, comparing different cohorts of stakeholders and, more importantly, patients/their carers.

The study draws attention to issues that emerge from the social responsibilities of healthcare organizations. Its findings provide new insights into the meaning of social responsibility in the healthcare sector in an Indian context from a stakeholder perspective.

The paper is based on an original study that addresses the current gap in the understanding of issues related to social responsibility by the various stakeholders of hospitals. It is particularly valuable for both the internal and external stakeholders of the healthcare organizations.

Investigation of the smoking model is important as it has a direct effect on human health. This paper focuses on the numerical analysis of the fractional order giving up smoking model. Nonetheless, due to observational or experimental errors, or any other circumstance, it may contain some incomplete information. Fuzzy sets can be used to deal with uncertainty. Yet, there may be some inconsistency in the membership as well. As a result, the primary goal of this proposed work is to numerically solve the model in a type-2 fuzzy environment.

Triangular perfect quasi type-2 fuzzy numbers (TPQT2FNs) are used to deal with the uncertainty in the model. In this work, concepts of r2-cut at r1-plane are used to model the problem's uncertain parameter. The Legendre wavelet method (LWM) is then utilised to solve the giving up smoking model in a type-2 fuzzy environment.

LWM has been effectively employed in conjunction with the r2-cut at r1-plane notion of type-2 fuzzy sets to solve the model. The LWM has the advantage of converting the non-linear fractional order model into a set of non-linear algebraic equations. LWM scheme solutions are found to be well agreed with RK4 scheme solutions. The existence and uniqueness of the model's solution have also been demonstrated.

To deal with the uncertainty, type-2 fuzzy numbers are used. The use of LWM in a type-2 fuzzy uncertain environment to achieve the model's required solutions is quite fascinating, and this is the key focus of this work.
