Shining a Spotlight on Stigma: Exploring Its Impact on Oral Health-Seeking Behaviours Through the Lenses of Patients and Caregivers.

Introduction The unique nature of a lack of good oral health, coupled with the lack of discussion and recognition surrounding the associated stigma, highlights it as a distinct issue. This stigma causes discomfort, devalues individuals, and necessitates urgent care and intervention. In Pakistan, a variety of reasons, including cultural beliefs, socioeconomic gaps, and poor access to dental care services, tend to exacerbate the stigma that is associated with dental care. This study aimed to determine the impact of stigma on oral health-seeking behaviours amongst the population of South Punjab in Pakistan. Methodology The study employed a qualitative design with a phenomenological approach, and the data collection was preceded by the administration of semi-structured interview guides and discussion guides to the patients and the consultant group, respectively. The targeted population was composed of patients who had reported stigmatization and a focus group of 10 dental consultants from various specialisations in dentistry. Data was collected until saturation from 16 patients who were recruited through the purposive convenience sampling technique. Results The study identified three themes, including perceived stigma impact on health-seeking behaviours and coping mechanisms; 10 subthemes emerged. Results showed social attitudes and unhealthy perceptions of oral conditions that lead to shame, loss of self-esteem, and lack of confidence among affected individuals. Behavioural reactions like mockery and discrimination further made it difficult for the participants who sought dental care and treatment. The study highlighted that stigma resulted in the avoidance of dental care, deterioration of oral health, and a tendency towards self-medication. People also used coping strategies such as hiding dental issues by avoiding social gatherings and seeking help from close friends to manage oral health stigma. Dental consultants had the strong opinion that care quality could be enhanced by utilising compassionate communication and patient education campaigns. Conclusions The experiences of patients and consultants related to dental stigma highlighted the complex interplay of sociocultural norms and healthcare practices. The study demonstrated that perceived stigma impacted the health-seeking behaviours of patients. Social support and education about oral health helped patients overcome this stigma. The study revealed that patients avoided dental treatments due to stigmatised behaviour from health professionals, a lack of affordability, and a feeling of shame to show and discuss the condition of their teeth, which got even worse due to self-remedy. The experiences of patients and consultants highlighted the need for increased advocacy, educational campaigns, and policies that can reduce inequalities in oral health and improve health equity. The study recommends specific intervention strategies and policy formulation to address oral health inequalities and contribute to advancing oral health equity in Pakistan.

Understanding the awareness of health and safety signs amongst health care workers in Pakistan - A cross-sectional study.

BACKGROUND: Safety signs are very important communication tools for accident prevention, fire safety, health hazard information, and emergency evacuation. However, they are helpful only when properly designed and understood by employees. OBJECTIVES: The purpose of the present study was to assess the awareness of health and safety signs amongst health care workers including doctors, dentists and paramedics in different health care sectors across Pakistan. METHODS: Data was collected via Google forms circulated through WhatsApp social media to predetermined groups of health care professionals to assess their understanding of safety signs across different health sectors. The survey included questions pertaining to awareness of 19 different health and safety signs complied with International Organization for Standardization 1710 and the Safety Signs and Signal Regulations 1996 chosen randomly. RESULTS: A total of 987 people participated in our study and were asked to comprehend the meaning of nineteen health and safety signs. The mean comprehension score for 19 signs was 42.2%. The mean score for warning signs was the lowest and fire safety signs was highest. The lowest comprehension scores were for oxygen cylinder sign (W029) 7.5% and highest for first aid sign (E003) 75.9%. Only two signs, that are first aid (E003) and mandatory gloves (M009) had acceptable comprehensive score of 75.9% and 73.7% respectively as per ISO 7010 i.e. >67%. Statistically significant differences were found only for trip hazard sign (W007) with respect to education and for risks of bomb explosion (W002), ionising radiation (W009), evacuation assembly point (E007), location of automated external heart defibrillator (E010) and mandatory gloves (M009) with work experience. CONCLUSION: Based on our results, we conclude that there is dire need of special and frequent training to better recognize the safety signs amongst health care employees since these kinds of interventions promote early detection of hazards and their associated risks. Thus, we propose that health care safety sign training must be included in every health care profession curriculum.

Biocatalytic PEI-PSS membranes through aqueous phase separation: influence of casting solution pH and operational temperature.

Biocatalytic membranes combine the separation properties of membranes and the catalytic abilities of enzymes, holding great promise for industries where both purification and conversion are required. In this work, polyelectrolyte complex membranes incorporated with lysozyme were prepared using polyethyleneimine (PEI) and poly(sodium 4-styrenesulfonate) (PSS) through a one-step and mild pH shift aqueous phase separation (APS) approach. The effects of lysozyme addition and casting solution pH on the membrane properties were studied. All the membranes, both with and without added lysozyme, exhibited asymmetric structures with relatively dense top surfaces and porous cross-sections with finger-like macrovoids. The incorporation of lysozyme did not significantly influence the structure and permeability of the formed membranes. The PEI-PSS biocatalytic membranes exhibited temperature dependent enzymatic activity. The activity strongly increased with increased operational temperature, with the highest activity of 4.30 ± 0.15 U cm-2 at 45 °C. This indicates a responsive effect, where a higher temperature leads to some swelling of the polyelectrolyte complex membrane, making the enzyme more accessible to the used substrate. Moreover, the biocatalytic membranes demonstrate desirable enzymatic stability, maintaining 60% activity even after 60 days of storage. This study validates the potential of the water-based APS process as a straightforward approach for integrating enzymes into responsive biocatalytic membranes.

Unleashing an Underlying Serious Cardiac Arrhythmia: A Case of Coronary Vasospasm With Atypical Presentation.

This case report highlights the atypical presentation of coronary artery vasospasm in a 59-year-old patient presenting with syncope due to ventricular arrhythmia. Despite initially elevated troponin levels and non-significant lesions observed during left heart catheterization, the patient experienced recurrent chest pain and dizziness, prompting further evaluation. Ultimately, coronary vasospasm was identified as the likely differential diagnosis, supported by various diagnostic modalities including electrocardiogram, Zio patch monitoring, transthoracic echocardiogram, cardiac MRI, and CT angiography. Management involved the initiation of calcium channel blocker therapy, leading to a non-eventful follow-up in the cardiology clinic.

The diaphragmatic defect was repaired with mesh via robotic surgery. The patient reported resolution of his symptoms at the six-month follow-up.

Traumatic optic neuropathy from an air gun pellet injury: a case report.

Orbital apex fractures are a debilitating condition that can cause vision problems and are often associated with intracranial injury. Traumatic Optic Neuropathy (TON), which results in vision loss following a traumatic injury to the optic nerve, can be caused by various mechanisms, but most cases involve injuries to the globe, orbit, or adnexa. We are reporting a case of an 18 year old male with a history of an air gun being accidentally discharged into his left eye. He was evaluated and found to have an Orbital apex fracture with left eye TON. Patient was administered high dose steroids. Detailed evaluation by Ophthalmology revealed a left eye traumatic stage I macular hole which was conservatively treated with visual improvement reported during patient follow up.

Effectiveness of Chitosan versus Natural Aloe Vera on Candida Adherence in Denture Soft Lining Material.

Background: Soft denture lining materials act as a cushion between the denture base and tissues. Alongside having many advantages, its main problem is candida growth due to its rubbery and porous texture. Many interventions have been performed to halt the growth of candida within soft lining materials such as the use of antifungal therapy and strict oral and denture hygiene but there are consequences such as recurrence, drug resistance, and toxicity related to these interventions. Since natural agents such as aloe vera and chitosan have been proven to have antibacterial and antifungal properties with minimum adverse effects, this study aimed to study the effectiveness of chitosan and aloe vera powders incorporated within denture soft lining materials against candida adherence. Methodology. A total of 60 soft-lining material samples were prepared that were equally divided into three groups, viz., group 1 (chitosan incorporation), group 2 (aloe vera incorporation), and group 3 (control). Candida was obtained from the microbiology lab to form a candidal suspension, diluted in 0.9% NaCl to match the McFarland standard bacteriologic solution. Samples were incubated at 37°C for 24 hours in test tubes containing 100 mL of the candidal suspension and 9.9 mL of the previously prepared Sabouraud dextrose agar. Crystal violet stain was used to stain the adhering cells by fixing them with methanol 80%. For each sample, the adhering candida cells were counted on three standard fields by using an inverted light microscope, and the mean of those fields was recorded. Results: The mean value for samples containing aloe vera was 41.15, while the mean values for samples containing chitosan and the control group were 16.05 and 79.1, respectively. Of all the three groups, aloe vera powder had a significant efficacy against candida growth as compared to the chitosan and control groups (P value = 0.001). Conclusion: Both herbal agents were effective against candida growth. In comparison, aloe vera was more effective against candida growth compared to chitosan.

Association between non-alcoholic fatty liver disease and coronary artery disease outcomes: A systematic review and meta-analysis.

OBJECTIVES: To evaluate the association between non-alcoholic fatty liver disease (NAFLD) and cardiovascular outcomes, including angina, coronary artery disease (CAD), coronary artery calcification (CAC), myocardial infarction (MI), and calcified coronary plaques. METHODS: A comprehensive search of databases, including PubMed, EMBASE, and Cochrane Library, was conducted up to January 2023. Studies were included investigating the relationship between NAFLD and cardiovascular outcomes in adult populations. Exclusion criteria were studies on animals, pediatric populations, and those not published in English. Two reviewers assessed the risk of bias in the included studies using the Newcastle-Ottawa Scale. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using random-effects models. RESULTS: The meta-analysis included 32 studies with a total of 5,610,990 participants. NAFLD demonstrated significant associations with increased risks of angina (Relative Risk (RR): 1.45, 95% CI: 1.17, 1.79), CAD (RR: 1.21, 95% CI: 1.07, 1.38), CAC >0 (RR: 1.39, 95% CI: 1.15, 1.69), and calcified coronary plaques (RR: 1.55, 95% CI: 1.05, 2.27). However, no significant association was found between NAFLD and CAC >100 (RR: 1.16, 95% CI: 0.97, 1.38) or MI (RR: 1.70, 95% CI: 0.16, 18.32). CONCLUSION: The meta-analysis demonstrated a significant association between NAFLD and cardiovascular outcomes independent of conventional cardiovascular disease (CVD) risk factors. These findings emphasize the importance of prevention, early detection, and proper management of NAFLD.

Early Assessment of Impact of Increased Value Added Tax on Smoking Behaviors and Financing among Adult Smokers in Saudi Arabia.

Background: Cigarette smoking has been identified as most perilous risk factor for several health ailments. Increased price may discourage smoking habits. There is limited literature available on impact of price rise on smoking behaviors in Saudi Arabia, which is the fourth largest importer of cigarettes and this study assessed the impact of tax increase (in 2020) on smoking behaviors. Methods: A cross-sectional survey was carried out between July 2021 and December 2021.i.e.one year after new value added tax (VAT) system came into force. Data was collected with 14-item pretested questionnaire from 721 adult smokers in Al-Jouf Region of Saudi Arabia selected through stratified cluster ransom sampling. We measured effects of tax increase on smoking behaviors, its impact on decision to quit and perceived health improvements as outcome variables. Results: Nearly 40% of the respondents said that increased price lead them to smoke less number of cigarettes per day (P=0.000), decreased smoking improved their health in terms of breathing capacity, mood, ability to exercise and sleep in hierarchy. 67.4% of the participants are currently thinking of quitting smoking due to increased prices (P=0.001) and logistic regression models identified reduced smoking due to tax rise (Odds=5.68), improvement in health (Odds=2.94) and excess spending of above 20% (Odds=1.72) significantly associated with intentions to quit smoking. Conclusion: Increased price of cigarettes due to VAT significantly decreased smoking behaviors and has impact on smokers' decision to quit smoking. Future studies needed to assess the long-term effect of increased tax on smoking behaviors and its relapse.

Carotidynia presenting as an atypical cause of unilateral neck pain in the emergency department.

Carotidynia is a rare presentation of atypical neck and face pain, which is due to inflammation around the carotid artery. Symptoms can get aggravated by head and neck movements, jaw movements and deglutition. It is usually a self- limiting illness, and it is treated conservatively with analgesics. Because of it is rarity, and partly due to physician's lack of understanding, it remains underdiagnosed. Our case report aims to shed light on the importance of how its diagnosis cannot be missed.

Assessment of parental acceptance towards different non-pharmacological behaviour management techniques in pediatric dental care-a cross-sectional study.

It is imperative to manage children with empathy and concern for their well-being in order to carry out any dental procedure smoothly. Owing to the inherent fear of dental operatory, behaviour management of children is an important aspect of pediatric dental care. Many techniques are available to help manage the behaviour of children. It is, however important to educate parents about these techniques and to get their cooperation for these techniques to be used on their children.This study aimed to familiarize the parents with non-pharmacological behavior management techniques and to determine the parental acceptance of such techniques in children seeking dental treatment in specialty care dental units. A total of 303 parents were evaluated through online questionnaires in this research. They were shown videos of randomly selected non-pharmacologic behaviour management techniques including tell-show-do, positive reinforcement, modelling and voice control. Parents were asked to watch the videos and give their response on seven-items inquiring about their acceptance levels regarding the respective techniques. The responses were recorded on a Likert scales ranging from strongly disagree to strongly agree. According to parental acceptance score (PAS), positive reinforcement was the most accepted technique whereas voice control was the least acceptable technique. Majority of the parents were more receptive towards those techniques that involved a healthy and friendly communication between a dentist and the pediatric patient such as, positive reinforcement, tell show do and modelling. Most significantly the people having low socio-economic status (SES) in Pakistan were more acceptable of voice control than people with high SES.

Late-onset pulmonary complications among survivors of coronavirus Disease 2019.

Objectives: To assess the late-onset pulmonary complications among survivors of coronavirus disease 2019. Methods: The cross-sectional analytical study was conducted in the department of Pulmonology, Sir Ganga Ram Hospital Lahore between October 2020 and March 2021. Total 288 patients visiting the hospital 12-week after recovery from COVID-19 enrolled using convenience sampling. After excluding patients (n=61) with a history of previous respiratory symptoms before the development of COVID-19, data from 227 patients was subjected to final analysis. Chest X-ray (CXR) was used to evaluate lung condition. Results: Participation of middle-aged adults (54.6%) was higher than older (38.3%) and young adults (7.0%). The percentage of males was 55.5% and smokers was 29.1%. Dyspnea was the most common complication as 80.0% patients had moderate to severe dyspnea while chronic cough was 78.0% and lung fibrosis (LF) was 13.2%. The chances of LF increased with the rise in age (p-value 0.033). However, the distribution of LF was similar between males and females. The frequency of lung fibrosis in smokers was 3-time higher than among non-smokers (24.2 vs. 8.7%; p-value 0.003). The patients with LF were more dependent on O2 as compared to the patients without LF (p-value < 0.001). The frequency of tachycardia was significantly different between patients with and without LF (all p-values < 0.05). Conclusion: LF is a common late-onset pulmonary complication of COVID-19 and is associated with old age, smoking, O2 dependency, tachycardia, and severe dyspnea.

Long-term statin therapy is associated with severe coronary artery calcification.

BACKGROUND: Atherosclerosis and consequent risk of cardiovascular events or mortality can be accurately assessed by quantifying coronary artery calcium score (CACS) derived from computed tomography. HMG-CoA-reductase inhibitors (statins) are the primary pharmacotherapy used to reduce cardiovascular events, yet there is growing data that support statin use may increase coronary calcification. We set out to determine the likelihood of severe CACS in the context of chronic statin therapy. METHODS: We established a retrospective, case-control study of 1,181 U.S. veterans without coronary artery disease (CAD) from a single site, the Providence VA Medical Center. Duration of statin therapy for primary prevention was divided into 5-year categorical increments. The primary outcome was CACS derived from low-dose lung cancer screening computed tomography (LCSCT), stratified by CACs severity (none = 0; mild = 1-99; moderate = 100-399; and severe ≥400 AU). Statin duration of zero served as the referent control. Ordinal logistic regression analysis determined the association between duration of statin use and CACS categories. Proportional odds assumption was tested using likelihood ratio test. Atherosclerotic cardiovascular disease (ASCVD) risk score, body mass index, and CKD (glomerular filtration rate of <60 ml/min/1.73 m2) were included in the adjustment models. RESULTS: The mean age of the study population was 64.7±7.2 years, and 706 (60%) patients were prescribed a statin at baseline. Duration of statin therapy was associated with greater odds of having increased CACS (>0-5 years, OR: 1.71 [CI: 1.34-2.18], p<0.001; >5-10 years, OR: 2.80 [CI: 2.01-3.90], p<0.001; >10 years, OR: 5.30 [CI: 3.23-8.70], p<0.001), and the relationship between statin duration and CACS remained significant after multivariate adjustment (>0-5 years, OR: 1.49 [CI: 1.16-1.92], p = 0.002; >5-10 years, OR: 2.38 [CI: 1.7-3.35], p<0.001; >10 years, OR: 4.48 [CI: 2.7-7.43], p<0.001). CONCLUSIONS: Long-term use of statins is associated with increased likelihood of severe CACS in patients with significant smoking history. The use of CACS to interpret cardiovascular event risk may require adjustment in the context of chronic statin therapy.

Thymus linearis Extracts Ameliorate Indices of Metabolic Syndrome in Sprague Dawley Rats.

Materials and Methods: The extract library (n-hexane (NH), ethyl acetate (EA), methanol (M), distilled water (DW), and combined extract (CE)) was standardized using in vitro phytochemical, antioxidant, and α-amylase inhibition assays, after which the protective effect of selected "hit," i.e., CE against metabolic syndrome, was determined in vivo, using rats fed a high-fat diet supplemented with additional cholesterol administration. CE was administered to Sprague Dawley rats in high dose as 100 mg/kg in carboxymethyl cellulose (CMC) (1 ml; 0.75% in DW) and low-dose group as 50 mg/kg in CMC (0.5 ml; 0.75% in DW). After 10 weeks, the effects of CE on insulin resistance, lipid metabolism, nonalcoholic fatty liver disease (NAFLD), oxidative stress, and genotoxicity were assessed through histological, biochemical, and hematological investigations. Results: Phytochemical analysis including RP-HPLC analysis of the extracts showed that flavonoids and phenolics (myricetin, kaempferol, and apigenin), previously known to be effective against obesity and diabetes, are present in the extracts. Antioxidant studies revealed that the plant possesses a highly significant (p < 0.05) concentration of antioxidants. Satisfactory α-amylase inhibitory activity was also observed in in vitro experiments. In vivo studies showed that CE-administered animals had significantly (p < 0.05) lower weight gain and smaller adipocytes than the control group. Moreover, CE resisted any significant (p < 0.05) change in the organ weights. Analogous to findings from its traditional use, the plant extract had a positive modulatory effect on insulin resistance and hyperglycemia. The study also indicated that CE resisted high-fat diet-induced disturbance in lipid profile and countered any pathological changes in liver enzymes caused by fat-infused diet. Furthermore, a study on endogenous antioxidant levels indicated that CE was effective in maintaining catalase and peroxidase levels within the normal range and resisted the effects of lipid peroxidation of thiobarbituric acid reactive substances. Conclusion: In principle, the current study's findings scientifically validate the implication of T. linearis in metabolic syndrome and recommend further studies on molecular insights of the observed therapeutic activity.

Thermal Generation in Spinal Surgery: Does Rate of Irrigation Matter During Anterior Cervical Discectomy?

BACKGROUND: High-speed rotational burring is considered the mainstay of modern spinal decompression surgery. However, high-energy burrs generate significant heat due to the friction between the bone and the rotating burr. This study determines the effects of automated irrigation rate on burr tip temperatures either with a serrated steel burr or diamond-coated burr during anterior cervical discectomy and fusion (ACDF). METHODS: This is an observational study of the routine practice of a single surgeon for 20 patients aged 18 years or older undergoing elective single- or multilevel ACDF. Various continuous irrigation rates of 0, 0.5, 1.0, or 2.0 cc/min were used. Forward-looking infrared thermography was used to measure the burr tip temperatures. The Midas Rex Legend EHS (Medtronic, PLC, Minneapolis, MN) stylus high-speed surgical drill was used with 3-mm burrs (diamond-coated and carbide-serrated steel) paired to the Medtronic Integrated Power Console set at 60,000 rpm. RESULTS: The 0.5-cc/min irrigation rate kept the maximum burr temperatures below 45°C (P < .001). With no irrigation (0 cc/min), the steel burrs reached a maximum of 141°C, and the diamond-coated burrs reached 177°C, which was the only significant difference related to the burr materials (P = 0.0354). With irrigation rates of 0.5 cc/min and above, the maximum recorded temperature for steel burrs was 40.6°C, and the maximum temperature for diamond-coated burrs was 38.9°C. Irrigation rates greater than 0.5 cc/min yielded little additional benefit. CONCLUSION: This study highlights the importance of adequate irrigation during high-speed burr drilling. Continuous irrigation is recommended even as low as 0.5 cc/min. It is good operative practice to reduce the risk of heat transmission to surrounding tissues, especially considering the proximity of cervical spinal nerve roots during uncoforaminal decompression.

Withametelin, a steroidal lactone, isolated from datura innoxa attenuates STZ-induced diabetic neuropathic pain in rats through inhibition of NF-kB/MAPK signaling.

Diabetic neuropathic pain is one of the microvascular complications of diabetes mellitus characterized by symmetrical pain and sensory abnormalities. A steroidal lactone isolated from the datura innoxa plant, withametelin (WMT), exhibited significant neuroprotective, anti-inflammatory, antioxidant, and anticancer properties. The current study aimed to investigate anti-neuropathic pain activity and the molecular mechanism of WMT against streptozotocin (STZ)-induced diabetic neuropathy. Rats were given a single injection of STZ (60 mg/kg, intraperitoneally (i.p.)) for induction of diabetes on the first day of the study. After the onset of diabetic neuropathy, pregabalin (10 mg/kg, i.p.) and WMT (0.1 and 1 mg/kg, i.p.) treatments were started from day 14 up to day 42. It was found that STZ-induced neuropathic pain behaviors were markedly reduced by WMT. It inhibited the STZ-associated histopathological changes and genotoxicity in the sciatic nerve and spinal cord. Additionally, Fourier transforms infrared (FTIR) spectroscopy results revealed that STZ-induced alterations in the biochemical components of the sciatic nerve's myelin sheath were inhibited by WMT. In the spinal cord, it markedly reduced the immunoreactivity of mitogen-activated protein kinases (MAPKs) signaling components such as p38-MAPK, c-Jun N-terminal kinase (JNK), extracellular-signal-regulated-kinase (ERK), and activator-protein 1 (AP-1). It also reduced the expression levels of nuclear factor-kappa-B (NF-κB), cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS). The production of inflammatory cytokines was considerably reduced by WMT. This study provides convincing evidence that WMT treatment attenuated STZ-induced diabetic neuropathic pain by inhibition of MAPK/NF-κB signaling.

Leiomyosarcoma: Lung Metastasis.

Uterine leiomyosarcoma distant metastasis is common, and lung metastasis has been reported. However, unique cases have been identified either with late onset of metastatic disease or with large size of lung metastasis. A typical approach to avoid metastasis would be a hysterectomy. Nonetheless, metastatic recurrence is common. We encountered a case at our hospital with leiomyosarcoma metastatic to the lungs. Lung metastasis was noted to be 17 cm in diameter. This size has not yet been reported in the literature to the best of our knowledge.
