Provision of smoking cessation support for patients following a diagnosis of cancer in Ireland. Prev Med Rep 2023; 32:102158. [PMID: 36875512 PMCID: PMC9982599 DOI: 10.1016/j.pmedr.2023.102158] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 02/15/2023] [Accepted: 02/17/2023] [Indexed: 02/22/2023] Open
Abstract
There is growing evidence that smoking cessation (SC) improves outcomes following diagnosis of cancer. Notwithstanding adverse outcomes, a significant number of those diagnosed with cancer continue to smoke. Our objective was to document the SC services provided for patients with cancer by specialist adult cancer hospitals across Ireland, a country with a stated tobacco endgame goal. A cross-sectional survey based on recent national clinical guidelines was used to determine SC care delivery across eight adult cancer specialist hospitals, and one specialist radiotherapy centre. Qualtrics was used. The response rate was 88.9% with data reported from seven cancer hospitals and one specialist radiotherapy centre, all indicating they had some SC related provision (100%). Stop smoking medications were provided to cancer inpatients in two hospitals, at outpatients and attending day ward services in one hospital. Smokers with cancer were referred automatically to the SC service in two hospitals at diagnosis. While stop smoking medications were available 24 h a day in five hospitals, most did not stock all three (Nicotine Replacement Therapy, Bupropion, Varenicline). One hospital advised they had data on uptake of SC services for smokers with cancer but were unable to provide detail. There is considerable variation in SC information and services provided to cancer patients across adult cancer specialist centres in Ireland, reflecting the suboptimal practice of smoking cessation for patients with cancer found in the limited international audits. Such audits are essential to demonstrate service gaps and provide a baseline for service improvement.

Development of a model to investigate the effects of prolonged ischaemia on the muscles of mastication of male Sprague Dawley rats. Arch Oral Biol 2023; 146:105602. [PMID: 36543038 DOI: 10.1016/j.archoralbio.2022.105602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Revised: 12/02/2022] [Accepted: 12/04/2022] [Indexed: 12/12/2022]
Abstract
OBJECTIVE The aims of this study were to develop a novel rodent model of masticatory muscle ischaemia via unilateral ligation of the external carotid artery (ECA), and to undertake a preliminary investigation to characterize its downstream effects on mechanosensitivity and cellular features of the masseter and temporalis muscles. DESIGN The right ECA of 18 male Sprague-Dawley rats was ligated under general anaesthesia. Mechanical detection thresholds (MDTs) at the masseter and temporalis bilaterally were measured immediately before ECA ligation and after euthanasia at 10-, 20-, and 35-days (n = 6 rats/timepoint). Tissue samples from both muscles and sides were harvested for histological analyses and for assessing changes in the expression of markers of hypoxia and muscle degeneration (Hif-1α, VegfA, and Fbxo32) via real time PCR. Data were analyzed using mixed effect models and non-parametric tests. Statistical significance was set at p < 0.05. RESULTS MDTs were higher in the right than left hemiface (p = 0.009) after 20 days. Histological changes indicative of muscle degeneration and fibrosis were observed in the right muscles. Hif-1α, VegfA, and Fbxo32 were more highly expressed in the masseter than temporalis muscles (all p < 0.05). Hif-1α and, VegfA did not change significantly with time in all muscles (all p > 0.05). Fbxo32 expression gradually increased in the right masseter (p = 0.024) and left temporalis (p = 0.05). CONCLUSIONS ECA ligation in rats induced hyposensitivity in the homolateral hemiface after 20 days accompanied by tissue degenerative changes. Our findings support the use of this model to study pathophysiologic mechanisms of masticatory muscle ischaemia in larger investigations.

Abstract
Background The benefits of smoking cessation (SC) for cancer patients are widely recognised. However, there has been a limited emphasis on SC in this context and it continues to be a challenge for cancer patients. As part of a larger feasibility study aiming to develop a structured SC pathway for cancer patients in Ireland, this qualitative study explored the SC practices, experiences and opinions of oncology healthcare professionals (HCPs). Methods Semi-structured interviews were conducted with 18 HCPs from lung, breast, cervical, head and neck and general oncology, across 4 specialist adult cancer hospitals in Ireland. Interview transcripts were analysed using thematic analysis. Results Four key themes emerged: (1) Frequently ask and advise but infrequently assist: most HCPs ask about smoking and many advise about available supports, but few refer patients to SC services. Where offered, referrals were to hospital SC services and/or nicotine replacement therapy was prescribed; no HCP prescribed varenicline or bupropion. Barriers included lack of time, ill-defined referral pathways and lack of knowledge. (2) Increased willingness but differing ability to quit: most patients were interested in quitting post diagnosis and had varying support needs, linked to cancer stage, social circumstances and stress levels. (3) Need for an integrated or parallel service: all HCPs suggested that a structured and defined referral pathway will facilitate SC. (4) Motivational counselling and pharmacotherapy combination: many HCPs suggested face to face as the best mode of intervention initially, with regular follow ups and ongoing support virtually, started pre-treatment, with an empathetic and empowering approach with provision of both motivational counselling and SC pharmacotherapy. Conclusions Smoking post cancer diagnosis has serious implications for cancer treatment and prognosis but is frequently overlooked. These findings will inform the design of a SC pathway for cancer patients. Key messages • Despite increased willingness to quit, there is inadequate and inconsistent SC support provision for cancer patients. • Tailored SC support should be an integral part of comprehensive cancer care.

Abstract
Abstract
Background
Higher rates of cancer are reported in smokers compared to non-smokers, and continued smoking following a cancer diagnosis is associated with reduced health outcomes and survival. Despite international evidence of increased risks, a substantial percentage of people with a cancer diagnosis continue to smoke. Patients may be unaware of the additional risks associated with continued smoking, and health care professionals may not engage with quit supports. As part of a larger feasibility study to develop a smoking cessation pathway in cancer services in Ireland, a rapid review of the evidence was completed.
Methods
Systematic searches of PubMed, Embase, and CINAHL 2015 to December 2020 were conducted; with studies restricted to adults with a cancer diagnosis [lung, breast, cervical, head and neck] and published in English. No restriction was placed on study designs. 6404 studies were identified and uploaded into COVIDENCE platform, Cochrane's systematic review methods were adopted throughout, PRISMA reporting guidelines were used, and narrative data synthesis was completed (CRD 42020214204).
Results
The twenty-three-studies report evidence from USA, Canada, England, Lebanon, and Australia. The setting for all interventions was hospitals and cancer clinics. Evidence identifies high dropout rates, inconsistencies in approaches and duration of smoking cessation interventions with varied outcomes. A wide-ranging number of critical components emerged associated with optimal quit support- including the timing of and frequency of quit conversations, use of electronic records, in-person support meetings, provision of nicotine replacement therapy and extended use of Varenicline, smoking cessation services embedded in oncology depts, and engaging with families wanting to quit at the same time.
Conclusions
Developing tailored smoking cessation interventions are needed for smokers diagnosed with cancer to enable engagement.
Key messages
• Continued smoking following a cancer diagnosis is associated with reduced health outcomes.
• Smoking cessation programmes for cancer patient should be tailored to meet needs.

Abstract
Abstract
We describe a rare congenital portosystemic shunt. A 37-year-old woman was found to have a previously unreported congenital shunt following investigations into secondary causes of hypertension. The abnormal venous shunt connected the splenic vein to the left ovarian vein. The patient underwent a laparoscopic procedure to successfully divide the shunt. She made a full recovery without complications. To our knowledge, this is the first presentation of a congenital portosystemic shunt involving the splenic and ovarian veins to be reported. This case demonstrates that such a shunt can be amenable for laparoscopic management. The case report shows preoperative scans and intraoperative images.

Abstract
Early clinical exposure (ECE) is a novel strategy for medical colleges to bridge the gap between basic and clinical sciences. There are few studies that explain student's and faculty's perspective on ECE. This study compares the ECE models (Case-based and Video-based case) in terms of benefits and challenges. This cross-over comparative study with 120 medical students of MBBS Batch 2019 and 8 facilitators was conducted in Government medical college, Pali, Rajasthan, India from September 2020 to March 2021. Entire batch was divided into two groups. In a hospital environment, one group was taught by an actual case (patient) of a specific topic, while another group was taught in a classroom setting by a video-based case. The students' and faculty's perspectives on Case-Based Early Clinical Exposure (CBECE) were documented using a pre-tested questionnaire and evaluated on a Likert scale. Finally, both groups were given assessment questions and the process was repeated in the following session of case based early clinical exposure, but with switched groups. Majority of the students (98.3%) agreed CBECE as more effective for attentiveness, retention, correlation of clinical knowledge with theoretical knowledge and communication. Most of the students (43.0%) believed that learning is limited due to lack of repeatability as compare with video-based case. Most of the facilitators found CBECE as effective tool for the development of attitude and communication skills of the students. CBECE can be implemented with limited sessions for sensitization of students about health care setup, importance of empathetic behavior, communication skill and better correlation of preclinical subjects in the context of disease.

Abstract
Abstract
Background
Regular breast self-examination (BSE) is a simple, cost-effective way of early breast cancer detection, particularly for women outside eligible screening age and for interval cancers. Although mammographic screening is the current most effective breast screening tool, the importance of regular BSE and breast awareness may be overlooked. The study aimed to identify socio-demographic, lifestyle and health-related factors associated with BSE practice among women in Ireland.
Methods
This study was conducted using Wave 4 data from The Irish Longitudinal Study on Ageing (TILDA), which collects health-related information from people aged 50 plus in biennial data collection waves. Those women aged 50-64 (eligible breast screening age in 2016) were selected. Following univariate analysis, logistic regression analysis was performed on selected variables to determine the factors independently associated with BSE practice.
Results
The prevalence of BSE was 70.7%. There was no significant association found between socio-demographic, lifestyle or health related factors and BSE. On logistic regression analysis, family history of cancer was not found to be associated with increased practice of BSE (Adjusted Odds Ratio (OR) 1.02, 95% Confidence Interval (CI) 0.79-1.31, p = 0.86). Having attended for mammogram showed a non-significant reduction in the likelihood of doing BSE (Adjusted OR 0.77, 95% CI 0.58-1.02, p = 0.07).
Conclusions
There are few studies on BSE from developed countries and this is the first from Ireland. BSE prevalence was 61%, 22.6% and 46.8% from Canada, United Kingdom and United States respectively, and was considerably lower from Asian and African countries. Women in this study were more educated than the general population counterparts, this might have overestimated BSE prevalence and obscured true associations. While we did not identify significant associations there is a suggestion that attending for mammography reduces women's interest in BSE.
Key messages
Being ‘Breast Aware’ and BSE are important alongside mammography for early detection of breast cancer. In countries where screening mammography is unavailable, BSE is an important detection tool.

Abstract
Abstract
Background
Population smoking rates are falling in Ireland, however many cancer patients continue smoking post diagnosis, despite its association with poorer treatment and clinical outcomes. As part of a feasibility study of smoking cessation for cancer patients in Ireland, a review of smoking rates in cancer patients was undertaken.
Methods
The Hospital Inpatient Enquiry system (HIPE), a national database which collects administrative, demographic & clinical data on discharges from public hospitals in Ireland, provided data (2014-2018) on smoking status of adult discharges with a cancer diagnosis (overall, breast, lung, cervical and head & neck (H&N). Smoking trends were compared with Healthy Ireland data (2015-2018), from a national survey for adults on health & wellbeing.
Results
During 2014-18, current smoking rose for all cancers (10.5%-11.4%), cervical cancer (11%-19.8%) and initially (2014-2016) for H&N (3%-12.7%) and lung (24.7%-27.2%), which dropped to 7.6% and 24% respectively in 2018; breast was stable at 6 ± 0.6%. Rates are lower than the general population (23%-20%). During 2014-17, past smoking rates demonstrated an upward trend among all cancers and specific cancers, with the highest prevalence among lung (30.3-39%) and lowest among breast (7.3-11%); comparative general population data was 23-28%. Current smoking rates for all cancers were highest among 50-59-year-olds (14-16%), which contrasts with the general population (24-35 years at 32-28%). Current and past smoking rates for all cancers were consistently higher among males, similar to the general population.
Conclusions
HIPE data is limited by duplicate episodes of care, and it is recognised that smoking documentation may be an underestimate. However, it is useful to analyse trends, as these limitations should be stable over the 5-year study period. Rates remain high; our further research will document barriers and facilitators to smoking cessation among cancer patients.
Key messages
Smoking rates in cancer patients are high despite proven benefits of smoking cessation. Supportive smoking cessation services as part of routine cancer care are indicated.

Abstract
Background The Intercollegiate General Surgery Guidance on COVID-19 recommended either non-surgical management or cholecystostomy drains for the management of acute biliary disease replacing gold standard practice of early laparoscopic cholecystectomy within 1 week of index admission with drainage reserved for high-risk patients where surgery is not appropriate. Method This is the retrospective study presenting the impact of gallstone disease in our unit during five months of the COVID- 19 pandemic (March 2020-August 2020) compared with the equivalent period in 2019. Results Patients presenting to the HPB unit with a coded diagnosis of gallstones were included and during the study period 1447 patients presented compared with 1413 in 2019. In 2020 compared with 2019 there was a significant decrease in patients presenting with cholecystitis (240 vs 313; p = 0.031) but no significant difference in patients presenting due to gallbladder perforation (44 vs 51). Interestingly the numbers of cholecystostomies were comparable, with 11 in 2020 and 15 in 2019 representing significantly less than the 7.2% figure published by Peckham-Cooper et al. Conclusions In our study there was a decrease in patients with cholecystitis and perforation and there was an increase in patients with gallstone pancreatitis, increase waiting lists with increase in the incidence of serious complications. In our trust we currently have 656 patients awaiting cholecystectomy compared to 280 in august 2019. With the recent elevation of the alert level to 4 and increased government restrictions, a consistent National approach is required to mitigate these risks.

Abstract
BACKGROUND New virtual resources ("novel resources") have been incorporated into medical education. No recent large studies about their use and perception among internal medicine (IM) residents exist. OBJECTIVE Characterize the use and perceived helpfulness of educational resources. DESIGN Nationwide survey from December 2019 to March 2020. PARTICIPANTS IM residents in the USA. MAIN MEASURES Residents were surveyed on their use and their perceived helpfulness of resources for both attaining general medical knowledge and for point-of-care (POC) learning. Traditional resources included board review resources, clinical experience, digital clinical resources (e.g., UpToDate), journal articles, pocket references, professional guidelines, textbooks, and residency curricula. Novel resources included Twitter, video streaming platforms (e.g., YouTube), online blogs, podcasts, and Wikipedia. KEY RESULTS We had 662 respondents from 55 residency programs across 26 states. On average, residents used 9 total resources (7 traditional and 2 novel). Digital clinical resources and clinical experience were used by all residents and found helpful by the highest percentage of residents (96% and 94%, respectively). Journal articles were next (used by 90%), followed by board review resources and residency curricula (both used by 85%). Their perceived helpfulness varied, from 90% for board review resources, to 66% for journal articles and 64% for residency curricula, the lowest perceived helpfulness of any traditional resource. Podcasts and video streaming platforms were used as frequently as textbooks (58-59%), but were rated as helpful more frequently (75% and 82% vs 66%, respectively). CONCLUSIONS Digital clinical resources, video streaming platforms, and podcasts were perceived as helpful, underscoring the importance of ensuring their integration into medical education to complement clinical experience and other traditional resources which remain highly valued by residents. IMPORTANCE Our findings can inform residency programs as they transition to virtual curricula in the wake of the COVID-19 pandemic.

Abstract
As data and metadata from the SARS-CoV-2 pandemic mature, the true impact on non-cancer, non-emergency surgical practice is becoming apparent. The authors present data on the impact of gallstone disease in their unit during 5 months of the COVID-19 pandemic (March 2020 to August 2020) compared with the equivalent period in 2019. Although the total number of patients presenting with gallstone disease was comparable, there was a decrease in patients with cholecystitis and perforation (although it is possibly too early for these to have presented), and there was a small but worrying increase in patients with gallstone pancreatitis. With the recent increase in alert level to 4 and increased government restrictions in an attempt to avoid a second national lockdown, a consistent national approach is required to mitigate these risks.

Abstract
The efficacy of scalp nerve block using 0.5% bupivacaine with adrenaline for postoperative pain relief in craniotomy patients was evaluated in 40 ASA I or II adult patients undergoing supratentorial craniotomy. A standard general anaesthesia technique was followed. Patients were randomly divided into two groups. Group B received 0.5% bupivacaine with 1:400,000 adrenaline and group S received normal saline with 1:400,000 adrenaline, both after skin closure. Postoperative pain was assessed at 30 seconds and 1, 2, 4, 6, 8 and 12 hours using a numerical rating scale. Diclofenac IM was administered as rescue analgesia if patients reported a numerical rating scale of 40 or more. Tramadol TV was administered as second rescue analgesia. Sixty per cent of patients in group S experienced moderate to severe pain (numerical rating scale of 40 or more) at some time during the first 12 postoperative hours in comparison to 25% patients in group B. Median pain scores were significantly lower in group B for up to 6 hours. Significantly more patients were pain free up to four hours in group B. Median duration for the requirement of first dose of diclofenac was longer in group B compared to group S (360 min vs 30 min, P<0.01). The number of doses of diclofenac (5 vs 19) was significantly lower in group B compared to group S (P<0.01). Tramadol was required by six patients in group S only. Scalp nerve block using 0.5% bupivacaine with 1:400,000 adrenaline decreases the incidence and severity of postoperative pain in patients undergoing supratentorial craniotomy.

Abstract
Treatment with the direct-acting antiviral agent (DAA) sofosbuvir (SOF), an NS5B inhibitor, and velpatasvir (VEL), an NS5A inhibitor, demonstrates viral cure rates of ≥95% in hepatitis C virus (HCV) genotypes (GT) 1-6. Here, we investigated intrapatient HCV diversity in NS5A and NS5B using Shannon entropy to examine the relationship between viral diversity and treatment outcome. At baseline, HCV diversity was lowest in patients infected with HCV GT3 as compared to the other GTs, and viral diversity was greater in NS5A than NS5B (P < .0001). Treatment outcome with SOF/VEL or the comparator regimen of SOF with ribavirin (RBV) was not correlated with baseline diversity. However, among persons treated with SOF/VEL, a decrease in diversity from baseline was observed at relapse in the majority virologic failures, consistent with a viral bottleneck event at relapse. In contrast, an increase in diversity was observed in 27% of SOF+RBV virologic failures. We investigated whether the increase in diversity was due to an increase in the transition rate, one mode of potential RBV-mediated mutagenesis; however, we found no evidence of this mechanism. Overall, we did not observe that viral diversity at baseline influenced treatment outcome, but the diversity changes observed at relapse can improve our understanding of RBV viral suppression in vivo.

Vpx-containing dendritic cell vaccine induces CTLs and reactivates latent HIV-1 in vitro. Gene Ther 2015; 22:227-36.

Abstract
Eradication of HIV-1 from an infected individual requires a means of inducing production of virus from latently infected cells and stimulating an immune response against the infected cells. We report the development of lentiviral vectors that transduce dendritic cells (DCs) to both induce production of virus from latently infected cells and stimulate antigen-specific CTLs. The vectors package Vpx, a lentiviral accessory protein that counteracts the SAMHD1-mediated block to DC transduction, allowing for long-term expression of vector-encoded proteins. The vectors encode influenza or HIV-1-derived epitopes fused via a self-cleaving peptide to CD40L that releases the peptide into the endoplasmic reticulum for entry into the antigen presentation pathway. Expression of CD40L caused transduced DCs to mature and produce Th1-skewing cytokines. The DCs presented antigen to CD8 T cells, enhancing antigen-specific CTLs. Coculture of the transduced DCs with latently infected cells induced high level virus production, an effect that was mediated by TNF-α. The ability of a DC vaccine to reactivate latent HIV-1 and stimulate an adaptive immune response provides a means to reduce the size of the latent reservoir in patients. This strategy can also be applied to develop DC vaccines for other diseases.

Abstract
AIM A double-blind randomized control trial was conducted to assess the effect of oral-transmucosal midazolam sedation on changes in anxiety levels of precooperative children during a Class II amalgam restorative procedure. METHODOLOGY A sample of 40 healthy, American Society of Anesthesiologists I, children aged 3-4 years having at least one carious primary mandibular molar requiring a Class II amalgam restoration with no previous dental history were randomly divided into experimental and control groups comprising of 20 children each. The children in the experimental group (Group I) received 0.5 mg/kg body weight of midazolam mixed in strawberry syrup and those in the control group (Group II) received the same syrup mixed in saline, 15 min prior to the restorative procedure. Routine nonpharmacological behavior management techniques were used in both groups. The anxiety levels were recorded using Venham's anxiety scale at the start and end of each procedural step. RESULTS There was a significant (P < 0.001) reduction in the anxiety levels of children in the experimental group on entry into the operatory compared with the control group. Introduction of each fear evoking stimuli showed a somewhat similar increase in anxiety levels in the two groups. In spite of a similar trend, the anxiety levels remained much lower in Group I than in Group II. CONCLUSION Midazolam in conjunction with behavior management is more helpful in relaxing the child initially than behavior management alone, thus increasing the chances of successful and easy accomplishment of further treatment steps.

Abstract
PURPOSE β-hemolytic streptococci (βHS) causes a diverse array of human infections. The molecular epidemiology of β-hemolytic streptococcal infections in trauma patients has not been studied. This study reports the molecular and clinical epidemiology of β-hemolytic streptococcal infections at a level 1 trauma centre of India. METHODS A total of 117 isolates of βHS were recovered from clinical samples of trauma patients. The isolates were identified to species level and subjected to antimicrobial susceptibility testing. Polymerase chain reaction (PCR) assay was done to detect exotoxin virulence genes. The M protein gene (emm gene) types of GAS strains were ascertained by sequencing. RESULTS Group A Streptococcus (GAS) was the most common isolate (64 %), followed by group G Streptococcus (23 %). A large proportion of GAS produced speB (99 %), smeZ (91 %), speF (95 %) and speG (87 %). smeZ was produced by 22 % of GGS. A total of 25 different emm types/subtypes were seen in GAS, with emm 11 being the most common. Resistance to tetracycline (69 %) and erythromycin (33 %) was commonly seen in GAS. CONCLUSIONS β-hemolytic streptococcal infections in Indian trauma patients are caused by GAS and non-GAS strains alike. A high diversity of emm types was seen in GAS isolates, with high macrolide and tetracycline resistance. SpeA was less commonly seen in Indian GAS isolates. There was no association between disease severity and exotoxin gene production.

Abstract
PURPOSE The objective of this study is to assess whether baseline optic nerve head (ONH) topography and retinal nerve fiber layer thickness (RNFLT) are predictive of glaucomatous visual-field progression in glaucoma suspect (GS) and glaucomatous eyes, and to calculate the level of risk associated with each of these parameters. METHODS Participants with ≥28 months of follow-up were recruited from the longitudinal Advanced Imaging for Glaucoma Study. All eyes underwent standard automated perimetry (SAP), confocal scanning laser ophthalmoscopy (CSLO), time-domain optical coherence tomography (TDOCT), and scanning laser polarimetry using enhanced corneal compensation (SLPECC) every 6 months. Visual-field progression was assessed using pointwise linear-regression analysis of SAP sensitivity values (progressor) and defined as significant sensitivity loss of >1 dB/year at ≥2 adjacent test locations in the same hemifield at P<0.01. Cox proportional hazard ratios (HR) were calculated to determine the predictive ability of baseline ONH and RNFL parameters for SAP progression using univariate and multivariate models. RESULTS Seventy-three eyes of 73 patients (43 GS and 30 glaucoma, mean age 63.2±9.5 years) were enrolled (mean follow-up 51.5±11.3 months). Four of 43 GS (9.3%) and 6 of 30 (20%) glaucomatous eyes demonstrated progression. Mean time to progression was 50.8±11.4 months. Using multivariate models, abnormal CSLO temporal-inferior Moorfields classification (HR=3.76, 95% confidence interval (CI): 1.02-6.80, P=0.04), SLPECC inferior RNFLT (per -1 μm, HR=1.38, 95% CI: 1.02-2.2, P=0.02), and TDOCT inferior RNFLT (per -1 μm, HR=1.11, 95% CI: 1.04-1.2, P=0.001) had significant HRs for SAP progression. CONCLUSION Abnormal baseline ONH topography and reduced inferior RNFL are predictive of SAP progression in GS and glaucomatous eyes.

Abstract
The objective of this study was to elucidate an association between Apo- Eε4 allele and CSF biomarkers Aβ42 and tau for the diagnosis of Alzheimer's Disease (AD) patients. Aβ42 and tau protein concentrations in CSF were measured by using ELISA assays. The levels of Aβ42 were found to be decreased where as tau levels increased in AD patients. Moreover in AD patients Apo-Eε4 allele carriers have shown low Aβ42 levels (328.86 ± 99.0 pg/ml) compared to Apo-Eε4 allele non-carriers (367.52 ± 5 7.37 pg/ml), while tau levels were higher in Apo-Eε4 allele carriers (511 ± 44.67 pg/ml) compared to Apo-Eε4 allele non-carriers (503.75 ± 41.08 pg/ml). Combination of Aβ42 and tau resulted in sensitivity of 75.38% and specificity of 94.82% and diagnostic accuracy of 84.30% for AD compared with the controls. Therefore low Aβ42 and elevated tau concentrations in CSF may prove to be a better diagnostic marker for AD along with the Apo-Eε4 allele.
