Abstract
Childhood callous-unemotional (CU) traits are characterized by low empathy, limited prosocial behavior, and restricted social affiliation. However, few studies have investigated whether CU traits are associated with different subtypes of prosocial and affiliative behavior or the specific motivational difficulties underlying these behaviors. We addressed these questions using data from 135 young children (M = 5.48 years old; 58% female) who viewed depictions of adults or children in instrumental need, emotional need, or neutral situations. We assessed recognition, suggested initiation of, and motivation for prosocial or affiliative behavior in response to each depiction. We distinguished between subtypes of prosocial (instrumental and emotional) and affiliative (parallel, cooperative, associative) behavior, as well as self- versus other-orientated motivations. Parents reported on child CU traits and conduct problems. Overall, children accurately recognized prosocial and neutral situations, offered help, and expressed other-orientated motivations for prosocial behavior and social motivations for affiliative behavior. Higher CU traits were related to lower overall recognition accuracy, which was more pronounced for emotional need. Higher CU traits were also related to fewer offers of help and more denial of prosocial behavior, particularly for instrumental need. Finally, CU traits were related to lower probability of initiating affiliative behavior. CU traits were not differentially related to self- versus other-orientated motivations for prosocial or affiliative behavior. Findings demonstrate difficulties of children with CU traits in recognizing need and offering help. Interventions for CU traits could include modules that explicitly scaffold and shape prosociality and social affiliation.

Abstract
Iron-sulfur (Fe-S) biogenesis requires multiprotein assembly systems, SUF and ISC, in most prokaryotes. M. tuberculosis (Mtb) encodes a complete SUF system, the depletion of which was bactericidal. The ISC operon is truncated to a single gene iscS (cysteine desulfurase), whose function remains uncertain. Here, we show that MtbΔiscS is bioenergetically deficient and hypersensitive to oxidative stress, antibiotics, and hypoxia. MtbΔiscS resisted killing by nitric oxide (NO). RNA sequencing indicates that IscS is important for expressing regulons of DosR and Fe-S-containing transcription factors, WhiB3 and SufR. Unlike wild-type Mtb, MtbΔiscS could not enter a stable persistent state, continued replicating in mice, and showed hypervirulence. The suf operon was overexpressed in MtbΔiscS during infection in a NO-dependent manner. Suppressing suf expression in MtbΔiscS either by CRISPR interference or upon infection in inducible NO-deficient mice arrests hypervirulence. Together, Mtb redesigned the ISC system to "fine-tune" the expression of SUF machinery for establishing persistence without causing detrimental disease in the host.

Abstract
The capacity of Mycobacterium tuberculosis (Mtb) to tolerate multiple antibiotics represents a major problem in tuberculosis (TB) management. Heterogeneity in Mtb populations is one of the factors that drives antibiotic tolerance during infection. However, the mechanisms underpinning this variation in bacterial population remain poorly understood. Here, we show that phagosomal acidification alters the redox physiology of Mtb to generate a population of replicating bacteria that display drug tolerance during infection. RNA sequencing of this redox-altered population revealed the involvement of iron-sulfur (Fe-S) cluster biogenesis, hydrogen sulfide (H2S) gas, and drug efflux pumps in antibiotic tolerance. The fraction of the pH- and redox-dependent tolerant population increased when Mtb infected macrophages with actively replicating HIV-1, suggesting that redox heterogeneity could contribute to high rates of TB therapy failure during HIV-TB coinfection. Pharmacological inhibition of phagosomal acidification by the antimalarial drug chloroquine (CQ) eradicated drug-tolerant Mtb, ameliorated lung pathology, and reduced postchemotherapeutic relapse in in vivo models. The pharmacological profile of CQ (C max and AUClast) exhibited no major drug-drug interaction when coadministered with first line anti-TB drugs in mice. Our data establish a link between phagosomal pH, redox metabolism, and drug tolerance in replicating Mtb and suggest repositioning of CQ to shorten TB therapy and achieve a relapse-free cure.

Abstract
Hands-on wet lab simulation training is a vital part of modern surgical training. Since 2010, surgical 'boot camps' have been run by many UK deaneries to teach core surgical trainees basic entry level skills. Training in advanced skills often requires attendance at national fee-paying courses. In the Wessex Deanery, multiple, free of charge, core surgical 'field camps' were developed to provide more advanced level teaching in the particular specialty preference of each core surgical trainee. After the COVID-19 pandemic, national hands-on courses will be challenging to provide and deanery-based advanced skills training may be the way forward for craft-based specialties. The experiences over 2 years of delivering the Wessex core surgical field camps are shared, giving a guide and advice for other trainers on how to run a field camp.

Abstract
RATIONALE Prostate cancer along with colorectal and lung cancers accounts for 42% of cancer cases in men globally. It is the first cancer indication for which the use of active immunotherapy, Sipuleucel-T (Provenge) was granted by the FDA in 2010. This study presents a case of prostate carcinoma and the tumour remission observed after administration of a personalised Dendritic cell vaccine (APCEDEN). PATIENT CONCERNS A 58 years old Caucasian male diagnosed with prostate carcinoma with GLEASON score 8. The patient had previously been diagnosed with Renal Cell Carcinoma (RCC) in 1996 and had undergone nephrectomy of the right kidney. PET CT scan revealed multiple intensely PSMA avid lesions noted in both lobes of the prostate gland with SUVmax -28.3 and the prostate gland measuring 3.2 × 3.2 cm displaying maximum dimensions. DIAGNOSIS FNAC followed by PETCT confirmed CA Prostate and further supported by increased serum PSA level. INTERVENTIONS The patient underwent personalised Dendritic Cell Immunotherapy APCEDEN regimen of six doses biweekly, in a time frame of 3 months were given both via intravenous and intradermal route. Six months post completion of APCEDEN, the patient was administered 6 booster shots for 6 months. OUTCOMES Progressive remission of carcinoma was observed along with reduction in PSA and Testosterone levels. PET CT showed decline in PSMA avidity by 50% with SUVmax -14.0 and normal size and shape of prostate gland. LESSONS Prostate carcinoma is the second most common cancer in men with majority of them exhibiting locally advanced disease. Apparently 20% to 30% of them are categorized as relapsed cases after various therapeutic interventions. Modulating immune system is an emerging therapy termed as Immunotherapy and potentiates the killing cancer cells via immune activation. Interestingly, prostate cancer is slow growing and it provides the scope and time to mount an anti-tumor response which makes it an attractive target for immunotherapy. This case study demonstrates the efficacy of APCEDEN Immunotherapy regimen resulting in a significant disease remission benefiting the patient.

Abstract
AIM To determine if recruitment of a hip fracture nurse specialist has a reduction in length of stay for hip fracture patients. METHOD Primary data was extracted from the National Hip Fracture Database (NHFD). The length of stay of hip fracture patients from 2011-2014 was compared to the period 2014-17, following appointment of a hip fracture nurse specialist in 2014. RESULTS The average length of stay in the first group (2011-2014) was 19.94 days and in the second group (2014-2017) was 16.52 days. There was a reduction of 3.42 days (17.15%) and was statistically significant. There was also a reduction in the time to surgery (1.38 days versus 1.15 days) and the crude 30-day mortality (10% versus 6.06%) both of which were statistically significant. The two groups were well-matched with regards to age, female: male ratio and severity of co-morbidities (based on American Society of Anaesthesiologists physical status classification system). CONCLUSION The introduction of a dedicated hip fracture nurse specialist has a positive outcome on hip fracture patients by reducing length of stay, time to surgery and the crude 30-day mortality.

Abstract
Of the most prevalent solid tumors with advanced disease, prostate and ovarian cancer and non-small cell lung carcinoma have the fewest therapeutic options. Herein, we report the case of a 63-year-old male with metastatic prostate adenocarcinoma showing substantial remission post-administration of personalized dendritic cell-based vaccine APCEDEN® in combination with chemotherapeutic drug Mitoxantrone. Therapeutic response displayed an interesting clinical correlation validated by PET scan images showing decreased fluorodeoxyglucose (FDG) avidity in the prostate gland, reduced skeletal metastases further established by the drop in serum Prostate Specific Antigen (PSA) levels and expression of immune assessment markers (IFN-γ, Tregs, neutrophil lymphocyte ratio and platelet lymphocyte ratio). This case demonstrates the potential efficacy of dendritic cell immunotherapy, showing a potent antitumor activity by enhancing the host immune responses, and improving quality of life. Prostate adenocarcinoma is the most common cancer and second leading cause of cancer-related death in men. Advanced cancers have very few therapeutic options. Understanding of the immune system has led to the development of novel personalized vaccines as an emerging and efficient treatment modality for cancer. This case study describes the substantial remission of advanced prostate cancer after receiving the personalized dendritic cell therapy APCEDEN in combination with the chemotherapy drug mitoxantrone, even after the patient’s previous failed treatment history of standard hormonal, chemo- and radiotherapy regimens. This case stands as an interesting example of combination therapy for cancer benefiting the patient.

Abstract
Background: Head and neck cancer is the sixth most common cancer worldwide. It is generally acknowledged that the early diagnosis of oral cancer may result in higher 5-year survival rates, less need for aggressive treatment and improved quality-of-life. There is therefore a need for a quantifiable, reliable and competency-based educational tool which can be used to train dentists and other health care providers in the early detection of oral cancers. Aim: To assess the effectiveness of “OralDETECT” spaced repetitive learning method for training dental professionals to become competent in the early detection of oral cancer. Methods: The current study involved training three dental professional groups: Oral Pathology/Oral Medicine/Oral Surgery specialists (x), Periodontists/Restorative dentists (y), General Dental Practitioners (z) and four undergraduate cohorts comprising 259 dental students from 3 different Malaysian dental schools. A structured one-day training program “OralDETECT” was conducted, consisting of a well-planned series of lectures, tests and discussions of the test answers. During the spaced discussions participants were trained on how to ask appropriate questions and look for clinical clues to arrive at the correct diagnosis of target [oral potentially malignant disorders/oral cancer (OPMD/OC)] and other nontarget lesions. The tests comprised one pretest and 4 posttests for the dental professional group, and one pretest and 3 posttests for the student groups. The overall and group mean scores were analyzed for all the tests conducted. The statistical evaluation was based on the percentage of correct answers (scores) for each test given by the participants. Repeated-measure ANOVA and post hoc Bonferroni´s test were carried out to examine the differences between test scores overall and for each group. All statistical analysis was carried out using SPSS software, where P values < 0.005 were considered significant. Results: The overall percentage of correct responses for both the dental professional and student groups increased from a minimum of 30% to above 80% from the pretest to the final posttest. There were significant differences in overall scores between all 4 posttests and the pretest for dental professional groups, and between all 3 posttests and the pretest for all student groups. The percentage of accuracy of diagnosis for the individual lesions (leukoplakia, lichen planus, erythroplakia, oral submucous fibrosis and suspicious of oral cancer) increased to > 80% for the Dental Professional groups. The percentage of diagnostic accuracy for the individual lesions also increased to > 80% (except for erythroplakia) for the student groups. Conclusion: Based on the results of our study the “OralDETECT” spaced repetitive learning method is an efficient and effective competency-based learning tool for teaching the early detection of OPMD and oral cancer among dental professionals and dental students.

Abstract
BACKGROUND The Helicobacter pylori infection is linked to chronic urticaria in nearly 60% of patients. We studied clinicoepidemiologic features in patients with chronic urticaria with and without H. pylori infection. METHODS Endoscopic antral biopsy for the rapid urease test (RUT) and histopathology, and serum IgG ELISA for H. pylori infection were performed in 150 patients (male:female ratio 1:2.4) of chronic urticaria aged 18-68 years. Clinicoepidemiologic features including age, gender, age of onset and duration, frequency and distribution of wheals, urticaria severity score, and systemic symptoms were analyzed in patients with and without H. pylori. The results of serum IgG ELISA for H. pylori were compared with 106 age- and gender-matched healthy adult controls. RESULTS The RUT in 84 patients (56%), histopathology in 76 patients (50.6%), and H. pylori IgG ELISA in 94 patients (62.6%) were positive. H. pylori IgG ELISA was positive only in 35 (33%) controls, suggesting that chronic urticaria patients were more likely to have asymptomatic H. pylori infection than normal controls. Although not statistically significant, patients with H. pylori had a higher mean urticaria severity score, number of urticaria/angioedema episodes per year, and involvement of more body sites, particularly the scalp, palms, and soles. The constitutional or gastrointestinal symptoms were statistically higher in patients with H. pylori infection than those without it. CONCLUSION A subset of chronic urticaria patients appears to have asymptomatic H. pylori infection. However, its implications in chronicity, recurrences, the severity of urticaria, other systemic manifestations, and management remains conjectural in view of 33% of controls also having positive H. pylori ELISA and the endemicity of infection in developing countries.

Abstract
AIM To investigate the efficacy of 0.2 mL vs. 0.6 mL of 2% lidocaine when given as a supplementary intraligamentary injection after a failed inferior alveolar nerve block (IANB). METHODOLOGY Ninety-seven adult patients with symptomatic irreversible pulpits received an IANB and root canal treatment was initiated. Pain during treatment was recorded using a visual analogue scale (Heft-Parker VAS). Patients with unsuccessful anaesthesia (n = 78) randomly received intraligamentary injection of either 0.2 mL or 0.6 mL of 2% lidocaine with 1 : 80 000 epinephrine. Root canal treatment was reinitiated. Success after primary injection or supplementary injection was defined as no or mild pain (HP VAS score ≤54 mm) during access preparation and root canal instrumentation. Heart rate was monitored using a finger pulse oximeter. The anaesthetic success rates were analysed with Pearson chi-square test at 5% significance levels. The heart rate changes were analysed using t-tests. RESULTS The intraligamentary injections with 0.2 mL solution gave an anaesthetic success rate of 64%, whilst the 0.6 mL was successful in 84% of cases with failed primary IANB. (χ2 = 4.3, P = 0.03). There was no significant effect of the volume of intraligamentary injection on the change in heart rate. CONCLUSIONS Increasing the volume of intraligamentary injection improved the success rates after a failed primary anaesthetic injection.

Abstract
This study aimed to compare the joint function and morphology achieved following condylar reconstruction using sternoclavicular grafts (SCG) versus transport distraction osteogenesis (TDO) in temporomandibular joint (TMJ) ankylosis patients. Twenty-two patients with TMJ ankylosis underwent TMJ reconstruction with SCG or TDO (n=11 each). Radiographic and clinical evaluations were performed at 1 week and at 1, 3, and 6 months post-surgery. Clinical criteria examined included the duration of surgery, mean postoperative mouth opening, excursive jaw movements, and pain scores. The radiographic evaluation 6 months postoperatively (computed tomography) included subjective assessment of joint morphology and measurements of the mean condylar height, width achieved, and amount of condylar resorption. The χ2 test and Student t-test were used to compare qualitative and quantitative variables, respectively. Similar mean mouth opening (SCG=31.8mm, TDO=32.1mm at 6 months), excursive movements, and pain scores were observed in the two groups throughout follow-up. Mean condylar resorption was significantly greater in the TDO group (TDO=7.0mm, SCG=2.7mm; P=0.005). The duration of reconstruction surgery was greater in the SCG group (P=0.035). A greater incidence of complications was observed with TDO. In conclusion, based on the protocols used in this study, SCGs are superior to TDO in terms of condylar morphology, stability, and surgical safety.

Abstract
BACKGROUND Direct to physician advertisements and direct to consumer advertisement (DTCA) is a well-known marketing strategy of pharmaceutical companies. Studies from the West and also from the Indian sub-continent revealed several lacunae in such advertisements. OBJECTIVES The present study was carried out to understand the international and national scenario regarding the lacunae in drug advertisements and the opinion of both physicians and patients regarding DTCA. METHODS The present study was conducted after obtaining approval from the institutional ethics committee. Warning letters (WLs) issued to pharmaceutical companies by United States Food and Drug Administration (USFDA) and Therapeutic Goods Administration (TGA) due to discrepancies in the advertisements were analyzed for reasons that were grouped into one of the following categories: overstatement of efficacy; unapproved indication; lack of adequate directions to use; omission of adverse effects; misleading claims; advertisement made for an unapproved drug (investigational new product). Drug advertisements in Current Index of Medical Specialties (CIMS) April-July 2014 issue was also analyzed for lacunae depending on categories as mentioned above. Physicians and patients in a tertiary care medical college and hospital were administered a validated questionnaire exploring their views about crucial aspects of DTCA. Descriptive statistics was used for each of the categories. RESULTS A total of 93 WLs issued by USFDA and 36 by TGA were assessed. Majority of the WLs by USFDA were issued for omission of adverse effects (61/93, 65.6%) followed by misleading claims (54/93, 58.1%). Similarly, WLs by TGA were also mainly issued for the presence of misleading claims (35/36, 97.2%) followed by overstatement of efficacy (26/36, 72.2%) and CIMS evaluation had revealed that 78/92 (84.8%) advertisements omitted adverse effects, 20/92 (21.7%) had misleading claims, 9/92 (9.8%) had unapproved indications and 7/92 (7.6%) overstated the efficacy. With regard to the opinion regarding DTCA, 69.9% physicians had a patient discussing DTCA that was clinically inappropriate. One hundred (64.5%) out of 155 physicians opined that DTCA encourage patients to attend physicians regarding preventive healthcare. On the contrary, 82/155 (52.9%) physicians felt that DTCA would damage the same. Similarly, 69 out of the total 100 patients felt that drug advertisements aid them to have better discussions with their treating physicians. Surprisingly, a large majority (91/100) were of the opinion that only safe drugs are allowed to be advertised. CONCLUSION To conclude, from the findings of this study both the physicians and patients should be cautious and not overzealous while dealing with drug advertisements or promotional literature. More stringent scrutiny and issue of WLs or blacklisting of indulging pharmaceutical companies are mandatory by the regulatory agency to contain the same.

Abstract
Tuberculosis (TB), caused by Mycobacterium tuberculosis (M. tuberculosis), is the leading infectious disease which claims one human life every 15-20s globally. The persistence of this deadly disease in human population can be attributed to the ability of the bacterium to stay in latent form. M. tuberculosis possesses a plethora of mechanisms not only to survive latently under harsh conditions inside the host but also modulate the host immune cells in its favour. Various M. tuberculosis gene families have also been described to play a role in this process. Recently, human bone marrow derived mesenchymal stem cells (MSCs) have been reported as a niche for dormant M. tuberculosis. MSCs possess abilities to alter the host immune response. The bacterium finds this self-renewal and immune privileged nature of MSCs very favourable not only to modulate the host immune system, with some help from its own genes, but also to avoid the external drug pressure. We suggest that the MSCs not only provide a resting place for M. tuberculosis but could also, by virtue of their intrinsic ability to disseminate in the body, explain the genesis of extra-pulmonary TB. A similar exploitation of stem cells by other bacterial pathogens is a distinct possibility. It may be likely that other intracellular bacterial pathogens adopt this strategy to 'piggy-back' on to ovarian stem cells to ensure vertical transmission and successful propagation to the next generation.

Abstract
1,3-Dipolar cycloaddition of azomethine ylides derived from acenaphthylene-1,2-dione and 5- methyl-benzo[b]-thiophene-2,3-dione with L-proline, thiazolidine-4-carboxylic acid and 1,2,3,4- tetrahydroisoquinoline-3-carboxylic acid with various electron deficient dipolarophiles leads to the formation of novel spiroheterocycles having two or more chiral centers. Semiempirical studies have been performed to understand the stereochemical course of the reaction. The synthesized cycloadducts have been screened for antimicrobial and toxicological activity.

Abstract
AIM The aim of this randomized controlled, double-blind trial was to comparatively evaluate the anaesthetic efficacy and injection pain of 1.8 mL of 2% lidocaine with different concentrations of epinephrine (1 : 80 000 and 1 : 200 000) in patients with symptomatic irreversible pulpitis. METHODOLOGY Sixty-two adult volunteers, actively experiencing pain, were randomly allocated into 2 groups and received 1.8 mL of 2% lidocaine with either 1 : 80 000 or 1 : 200 000 epinephrine concentration. Endodontic access preparation was initiated 15 min after the initial IANB. Pain during treatment was recorded using the Heft-Parker visual analogue scale (HP VAS). The primary outcome measure, and the definition of 'success', was the ability to undertake pulp access and canal instrumentation with no or mild pain (HP VAS score <55 mm). Secondary outcome measure was the pain experienced during LA solution deposition. Statistical analysis was performed using Mann-Whitney U-test and chi-square test. RESULTS The anaesthetic success rates of 2% lidocaine solutions containing 1 : 80 000 and 1 : 200 000 epinephrine concentrations were 20% and 28%, respectively. The difference was not statistically significant. There was also no significant difference in the pain experienced during deposition of the solutions. CONCLUSIONS Two percent lidocaine solution used for IANB achieved similar success rates when used with 1 : 80 000 or 1 : 200 000 epinephrine concentration.

Abstract
Tuberculosis, caused by Mycobacterium tuberculosis, remains a leading infectious disease taking one human life every 15 s globally. The two well-characterized strains H37Rv and H37Ra, derived from the same parental strain M. tuberculosis H37, show dramatically different pathogenic phenotypes. PE/PPE gene family, comprising of 176 open reading frames and present exclusively in genus Mycobacterium, accounts for ∼10% of the M. tuberculosis genome. Our comprehensive in silico analyses of PE/PPE family of H37Ra and virulent H37Rv strains revealed genetic differences between these strains in terms of several single nucleotide variations and InDels and these manifested in changes in physico-chemical properties, phosphorylation sites, and protein: protein interacting domains of the corresponding proteomes. Similar comparisons using the 13 sigma factor genes, 36 members of the mammalian cell entry family, 13 mycobacterial membrane protein large family members and 11 two-component signal transduction systems along with 5 orphaned response regulators and 2 orphaned sensor kinases failed to reveal very significant difference between H37Rv and H37Ra, reinforcing the importance of PE/PPE genes. Many of these changes between H37Rv and H37Ra can be correlated to differences in pathogenesis and virulence of the two strains.

Abstract
Our aim was (i) to investigate the hypothalamo-hypophyseal-gonadal axis in hyperthyroid Indian males, (ii) to rule out the modulatory role of adrenal steroids on it and (iii) to determine if the simultaneous rise in oestradiol and luteinising hormone (LH) in hyperthyroid males is due to a positive feedback action of oestradiol on pituitary LH release. Age- and BMI-matched men were divided into two groups, I, euthyroid subjects (n = 17) and II, hyperthyroid patients (n = 12) on the basis of their thyroid hormone levels. Serum levels of thyroid-stimulating hormone, triiodothyronine, thyroxine, LH, follicle-stimulating hormone (FSH), prolactin, E(2), T, P(4), sex hormone binding globulin and dehydroepiandrosterone sulphate (DHEAS) were assayed. Mean levels of T and E(2) were approximately two times higher in group II in comparison with group I. DHEAS levels were similar in both groups ruling out any adrenal involvement. Mean serum LH level was 2.6 folds higher in group II in comparison with group I. Mean serum levels of FSH were higher in group II, it was marginally nonsignificant. On the basis of these and previous observations, we hypothesise that endocrinological dimorphism in human male and female is not rigid; a sustained rise in serum oestradiol probably induces a positive feedback action on pituitary leading to elevated gonadotrophin levels.

Abstract
End-stage kidney disease (ESKD) patients on maintenance hemodialysis (MHD) have a lot of anxiety. Anxiety and coping are associated with the locus of control; the present investigation aimed to study the state and trait anxiety, locus of control, and active and passive coping among patients on MHD. Thirty MHD patients and 30 controls were administered State-Trait Anxiety Inventory, Rotter's Locus of Control Scale, and Coping Responses Inventory. There were significantly higher scores on state and trait anxiety, respectively (67.53 ± 10.89 vs. 59.40 ± 6.97, P < 0.01, and 62.97 ± 8.45 vs. 58.07 ± 7.06, P < 0.05), and locus of control (11.27 ± 3.55 vs. 9.04 ± 1.86, P < 0.01) in patients as compared to controls. On coping responses, patients and controls differed on positive reappraisal (54.33 ± 4.67 vs. 51.17 ± 3.12, P < 0.01), seeking guidance and support (58.07 ± 5.51 vs. 53.27 ± 4.22, P < 0.01), problem solving (51.03 ± 4.70 vs. 47.57 ± 4.73, P < 0.01), cognitive avoidance (60.27 ± 6.76 vs. 56.80 ± 4.08, P < 0.05), acceptance or resignation (61.67 ± 6.30 vs. 58.83 ± 4.23, P < 0.01), emotional discharge (68.07 ± 6.78 vs. 64.30 ± 4.50, P < 0.05), approach coping (205.57 ± 10.55 vs. 189.70 ± 11.37, P < 0.01), and avoidance coping (255.30 ± 16.45 vs. 241.10 ± 10.50, P < 0.01). A higher prevalence of anxiety trait could be the cause of anxiety in MHD patients besides the medical problems. The locus of control among patients though a mixed one was significantly more toward externalism. Thus, there is a need to identify this group well in advance and prepared not only medically but also psychologically for MHD.

Abstract
9609 Background: Patients undergoing treatment for cancer often report problems with their cognitive function (CF), which is an essential component in maintaining Quality of Life (QoL). We conducted a longitudinal study of lung cancer (LC) patients to systematically evaluate changes in QOL including changes in CF, over time. Methods: Between 2005–2008, we followed 1757 primary LC patients who responded to CF questions at least once within 8 years of diagnosis. Overall QoL measured by LCSS and LASA (scores 0–100 from worst to best) were assessed among 1,604 of 1,757 (91%) who completed the questionnaire at one or both of two time periods: short-term (T1-within 3 years of diagnosis) and long-term follow-up (T2-beyond 5 years of diagnosis). Questions rated overall CF and problems in thinking clearly. Results: The median age at the time of LC diagnosis was 68 years in men (n=834) and 65 years in women (n=770), p<0.0001. At T1, the mean score of patients reporting problems with CF was 63.2 (±22.45) vs 74.4 (±20.38) who reported no problems (p<0.0001). At T2, the mean score was 62.2 (±24.18) for patients who reported CF problems and 78.1 (±18.28) who reported no changes with their CF (p<0.0001). At T1, the mean score of patients reporting problems thinking clearly was 66.1 (±21.65) vs 75.6 (±20.21) reporting no problems with their thinking (p<0.0001). At T2, the mean score was 70.4 (±20.95) for patients reporting problems thinking clearly vs 82.6 (±17.76) who reported no problems (p<0.0001). Conclusions: Self-reported QoL of lung cancer survivors showed substantial deficits with their cognitive function. Prospective and objective assessments are needed to determine if cancer treatments are positively associated with cognitive decline, to identify the patients at risk, and to test appropriate interventions.

Out of a total of 16,500 cases, NHL was reported in 154 (0.93%)cases. The median age was 52 yrs and the no. of male patients were 104 and female were 50 making M:F = 2:1. The type of NHL was B-Cell type (CD-20+ve) in 132(85%) and T-Cell type (CD 3+ve) in 22 (15%) cases. Out of 154 patients, 77 were nodal and 77 were extra nodal. Additional features - HIV positivity in 2 patients, autoimmune haemolytic disease in 1 patient and thalessemia major in 1 patient. In extra-nodal group of NHL patients the no. Of male and female patients were 55 & 22 respectively (M:F=2.5:1). Out of 77 extra-nodal cases, 31(20%) were GIT NHL (Stomach -16, Colon-8, Ileum-4, and Duodenum-3) and out of the rest 46 extra-nodal cases the site of origin was - head & neck-14, skin n soft tissues -8, primary CNS-6, testicular-4, para-spinal- 3, breast mass-3, perinephric-2, bones-2 and 1 each in cervix, lung mass, liver and cervical plexus. Methods: A detailed analysis of 31 GIT NHL cases was carried out. 28 out of 31 were B-Cell type and 3 were T-Cell type. 26 out of 31 were diffuse large cell variety, 2 were mixed small & large cell variety and 1 MALT variety. In 2 patients the type of lymphoma could not be ascertained. Bone marrow infiltration was present in 2 out of 31 cases of GIT Lymphoma. Surgery was carried out in 15 of 31 GIT NHL cases and these were arising from Colon, Ileum and Duodenum. No surgery was performed in patients with stomach lymphoma. Results: Of all the extra-nodal cases chemotherapy was given to 39 patients - R-CHOP = 20 patients, CHOP = 13 patients, high dose MTX in primary CNS NHL = 6 patients. CR was achieved 16 out of 20 R-CHOP patients (80%), 8 out of 13 CHOP Patients (61 %) and 4 out of 6 high dose MTX patients (66%). No significant financial relationships to disclose.

Abstract
9004 Background: Patients receiving treatment for cancer can experience a diminution of their cognitive abilities which can persist for many years after. The present study examined the potential of modafinil as a cognitive enhancer on memory and attention in a randomized clinical trial in breast cancer patients following completion of treatment. Methods: Breast cancer patients who reported a score of = 2 on the Brief Fatigue Inventory (BFI) an average of 22.8 months following completion of chemotherapy were enrolled. In Phase 1, patients received 200mg modafinil open-label once daily for 4 weeks. In Phase 2, patients with a positive response following Phase 1 were randomized either to an additional 4 weeks of modafinil or to placebo. Tests of memory and attention selected from the Cognitive Drug Research (CDR) computerized cognitive assessment were performed at baseline (before modafinil) and after completing Phase 1 and 2. The difference between scores at baseline and scores at Phase 1 and Phase 2, were subjected to a Wilcoxon's signed rank test. Results: Of the 82 women enrolled, 68 completed all 3 CDR assessments in the study (range=33–83 years, median age=54 years). At the end of Phase 1 (week 4), modafinil had a significant effect on the Speed of Memory Index (p=0.0047) and the Digit Vigilance Test (p=0.0014) but showed no significant effect on Quality of Working Memory (p=0.3528) nor on Power of Attention (p=0.8953). At the end of phase 2 (week 8), the group that continued modafinil demonstrated improved Mean Continuity of Attention (p=0.0002) compared with the placebo group and also demonstrated significantly greater improvements in Quality of Episodic Secondary Memory relative to placebo (p<0.005). This improvement was observed at week 4, and was maintained throughout the study. Finally, continued modafinil demonstrated significantly greater improvement in Speed of Memory relative to placebo (p=0.009). Conclusions: Modafinil provides significant improvements in attention and speed of memory for breast cancer patients following their treatment of cancer. Although further study is needed, these findings suggest that modafinil may enhance quality of life in this patient population.
