Assessment of Gonadotropins Level and Their Ratio In Gallstone Patients In Kolkata: A Cross-Sectional Study

Whole genome sequence-based molecular characterization of blood isolates of carbapenem-resistant Enterobacter cloacae complex from ICU patients in Kolkata, India, during 2017-2022: emergence of phylogenetically heterogeneous Enterobacter hormaechei subsp. xiangfangensis.

Blood-borne infections caused by the carbapenem-resistant Enterobacter cloacae complex (CR-ECC) are major public threats with respect to the challenges encountered during treatment. This study describes the whole genome sequencing-based molecular characteristics of blood isolates (n = 70) of CR-ECC from patients admitted to the intensive care unit of tertiary care hospitals in Kolkata, India, during 2017-2022 with respect to species identification, antimicrobial resistance (AMR) profiling, mechanism of drug resistance, and molecular subtypes. Vitek2 MALDI and species-specific PCR identified Enterobacter hormaechei subsp. xiangfangensis (47.14%) as the emerging CR-ECC subspecies in Kolkata. The predominating carbapenemase and extended-spectrum β-lactamase genes found were blaNDM-1 (51.42%) and blaCTX-M-15 (27%), respectively. Besides, blaNDM-4, blaNDM-5, blaNDM-7, blaCMH-3, blaSFO-1, blaOXA-181, blaOXA-232, blaKPC-3, and blaDHA-7 genes were also detected, which were not previously reported from India. A multitude of Class 1 integrons (including In180, In4874, In4887, and In4888, which were novel) and plasmid replicon types (IncFIB, IncFII, IncX3, IncHI1-HI2, IncC, and IncR) involved in AMR dissemination were identified. Reverse transcription-PCR and western blot revealed that carbapenem resistance in non-carbapenemase-producing CR-ECC isolates was contributed by elevated levels of ampC, overexpression of acrAB, and loss of ompF. A total of 30 distinct sequence types (STs) were ascertained by multi-locus sequence typing; of which, ST2011, ST2018, ST2055, ST2721, and ST2722 were novel STs. Pulsed-field gel electrophoresis analysis showed heterogeneity (69 pulsotypes with a similarity coefficient of 48.40%) among the circulating isolates, suggesting multiple reservoirs of infections in humans. Phylogenetically and genetically diverse CR-ECC with multiple AMR mechanisms mandates close monitoring of nosocomial infections caused by these isolates to forestall the transmission and dissemination of AMR.IMPORTANCEThe emergence and extensive dissemination of the carbapenem-resistant Enterobacter cloacae complex (CR-ECC) have positioned it as a critical nosocomial global pathogen. The dearth of a comprehensive molecular study pertaining to CR-ECC necessitated this study, which is the first of its kind from India. Characterization of blood isolates of CR-ECC over the last 6 years revealed Enterobacter hormaechei subsp. xiangfangensis as the most prevalent subsp., exhibiting resistance to almost all antibiotics currently in use and harboring diverse transmissible carbapenemase genes. Besides the predominating blaNDM-1 and blaCTX-M-15, we document diverse carbapenemase and AmpC genes, such as blaNDM-4, blaNDM-7, blaOXA-181, blaOXA-232, blaKPC-3, blaCMH-3, blaSFO-1, and blaDHA-7, in CR-ECC, which were not previously reported from India. Furthermore, novel integrons and sequence types were identified. Our findings emphasize the need for strengthened vigilance for molecular epidemiological surveillance of CR-ECC due to the presence of epidemic clones with a phylogenetically diverse and wide array of antimicrobial resistance genes in vulnerable populations.

Prevalence and changing antimicrobial resistance profiles of Shigella spp. isolated from diarrheal patients in Kolkata during 2011-2019.

The primary aim of this study was to investigate the occurrence, characteristics, and antimicrobial resistance patterns of various Shigella serogroups isolated from patients with acute diarrhea of the Infectious Diseases Hospital in Kolkata from 2011-2019. During the study period, Shigella isolates were tested for their serogroups, antibiotic resistance pattern and virulence gene profiles. A total of 5.8% of Shigella spp. were isolated, among which S. flexneri (76.1%) was the highest, followed by S. sonnei (18.7%), S. boydii (3.4%), and S. dysenteriae (1.8%). Antimicrobial resistance against nalidixic acid was higher in almost all the Shigella isolates, while the resistance to β-lactamases, fluoroquinolones, tetracycline, and chloramphenicol diverged. The occurrence of multidrug resistance was found to be linked with various genes encoding drug-resistance, multiple mutations in the topoisomerase genes, and mobile genetic elements. All the isolates were positive for the invasion plasmid antigen H gene (ipaH). Dendrogram analysis of the plasmid and pulsed-field electrophoresis (PFGE) profiles revealed 70-80% clonal similarity among each Shigella serotype. This comprehensive long-term surveillance report highlights the clonal diversity of clinical Shigella strains circulating in Kolkata, India, and shows alarming resistance trends towards recommended antibiotics. The elucidation of this study's outcome is helpful not only in identifying emerging antimicrobial resistance patterns of Shigella spp. but also in developing treatment guidelines appropriate for this region.

Prevalence of Chikungunya and Scrub Typhus Coinfection among Dengue Negative Patients in Kolkata, India-A Newly Emerging Public Health Hazard

The chikungunya virus (CHIKV) and scrub typhus infection has scattered worldwide creating human health hazards in India and Asia specific region. We aimed to identify chikungunya, scrub typhus, and their co-infection in dengue-negative samples having undifferentiated febrile illnesses. Enzyme linked immunosorbent assay (ELISA) methods were used to detect the chikungunya and scrub typhus specific IgM antibody by using chikungunya IgM capture ELISA kit and scrub typhus IgM Microlisa ELISA kit, respectively. OD value was measured with the help of BeneSphera (India) ELISA microplate reader. Among 490 suspected patients, 57 (11.63%) samples were tested positive for chikungunya IgM antibodies, while 43 (8.77%) came positive for scrub typhus IgM antibodies, but all samples tested negative for dengue IgM antibodies. Additionally, 5% of the total positive cases were positive for both chikungunya and scrub typhus infection. Our study offers a hypothesis regarding one of the possible causes of the decline in the frequency of scrub typhus and chikungunya cases reported in Kolkata and other districts of West Bengal. As an outcome, physicians treating undifferentiated febrile patients in endemic locations should look for chikungunya, scrub typhus, and existing coinfection between them to avoid delayed diagnosis and provide proper treatment against these infections.

Metagenomic analysis of diarrheal stools in Kolkata, India, indicates the possibility of subclinical infection of Vibrio cholerae O1

We examined the stools of 23 patients in Kolkata, who were diagnosed as cholera patients because Vibrio cholerae O1 was detected from their stools by culturing methods, and further explored by metagenomic sequencing analysis. Subsequently, the presence of the gene encoding A subunit of cholera toxin (ctxA) and the cholera toxin (CT) level in these stool samples were examined. ctxA was examined by both metagenomic sequencing analysis and polymerase chain reaction. In these examinations, two samples did not show positive in any of these tests. The metagenomic analysis showed that the genes for Streptococcus pneumoniae and Salmonella enterica were present in the stools of these two patients, respectively. Therefore, these two patients were not considered to have diarrhea due to V. cholerae infection. From these results, we predicted that some Kolkata residents harbor a small number of V. cholerae in their intestines as a form of subclinical infection with V. cholerae. Next, we analyzed the stool samples of 22 diarrhea patients from which V. cholerae was not isolated. The results showed that 3 of the patients seemed to have subclinical infection of V. cholerae based on the amount of the genes. These results indicated that subclinical infections with V. cholerae O1 occur in Kolkata.

Characterization of NDM-5 Carbapenemase-Encoding Gene (bla NDM-5) - Positive Multidrug Resistant Commensal Escherichia coli from Diarrheal Patients.

PurposeThe multidrug resistance Enterobacteriaceae cause many serious infections resulting in prolonged hospitalization, increased treatment charges and mortality rate. In this study, we characterized blaNDM-5-positive multidrug resistance commensal Escherichia coli (CE) isolated from diarrheal patients in Kolkata, India.MethodsThree CE strains were isolated from diarrheal stools, which were negative for different pathogroups of diarrheagenic E. coli (DEC). The presence of carbapenemases encoding genes and other antimicrobial resistance genes (ARGs) was detected using PCR. The genetic arrangement adjoining blaNDM-5 was investigated by plasmid genome sequencing. The genetic relatedness of the strains was determined by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) methods.ResultsIn addition to colistin, the blaNDM-5-positive CE strains showed resistance to most of the antibiotics. Higher MICs were detected for ciprofloxacin (>32 mg/L) and imipenem (8 mg/L). Molecular typing revealed that three CE strains belonged to two different STs (ST 101 and ST 648) but they were 95% similar in the PFGE analysis. Screening for ARGs revealed that CE strains harbored Int-1, blaTEM, blaCTX-M3, blaOXA-1, blaOXA-7, blaOXA-9, tetA, strA, aadA1, aadB, sul2, floR, mph(A), and aac(6´)-Ib-cr. In conjugation experiment, transfer frequencies ranged from 2.5×10−3 to 8.4x10−5. The blaNDM-5 gene was located on a 94-kb pNDM-TC-CE-89 type plasmid, which is highly similar to the IncFII plasmid harboring an IS26-IS30-blaNDM-5-bleMBL-trpF-dsbd-IS91-dhps structure.ConclusionTo the best of our knowledge, this is the first report on carbapenem resistance involving the blaNDM-5 gene in CE from diarrheal patients. The circulation of blaNDM-5 gene in CE is worrisome, since it has the potential to transfer blaNDM-5 gene to other enteric pathogens.

Characterization of diarrhoeagenic Escherichia coli with special reference to antimicrobial resistance isolated from hospitalized diarrhoeal patients in Kolkata (2012-2019), India.

This study analyses the prevalence and antimicrobial resistance (AMR) of major diarrhoeagenic Escherichia coli (DEC) pathotypes detected in hospitalized diarrhoeal patients in Kolkata, India, during 2012-2019. A total of 8891 stool samples were collected from the Infectious Diseases Hospital, Kolkata and screened for the presence of enteric pathogens. Multiplex PCR identified the presence of DEC in 7.8% of the samples, in which ETEC was most common (47.7%) followed by EAEC (38.4%) and EPEC (13.9%). About 54% cases were due to sole DEC infections. Majority of the mixed DEC infections were caused by the Vibrio spp. (19.1%) followed by Rotavirus (14.1%) and Campylobacter spp. (8.4%). ETEC and EAEC were associated significantly with diarrhoea in children <5 years of age, whereas EPEC and also ETEC were prevalent in patients aged between 5 and 14 years. AMR profile showed high prevalence of multidrug resistance (MDR) among DEC (56.9%) in which 9% were resistant to antibiotics of six different antimicrobial classes. Screening of the AMR conferring genes of DEC showed the presence of blaCTX-M3 (30.2%) in highest number followed by blaTEM (27.5%), tetB (18%), sul2 (12.6%), strA (11.8%), aadA1 (9.8%), blaOXA-1 (9%), dfrA1 (1.6%) and blaSHV (1.2%). These findings highlighted the high prevalence of MDR in major DEC pathotypes that could be considered as the leading aetiological bacterial agent responsible for diarrhoea and suggests a significant public health threat. The results of this study can help to improve the understanding of the epidemiology of DEC infections in patients with diarrhoea. Monitoring of AMR surveillance needs special attention because the DEC isolates were highly resistant to commonly used antimicrobials in the treatment of diarrhoea.

The Impact of Socioeconomic Status on the Psychological Distress of Breast Cancer Patients in Kolkata"

Background: Breast cancer patients experience a variety of psychological symptoms such as anxiety, depression that affect their quality of life. The present study probed whether the socioeconomic status had any significance on psychological distress and quality of life of breast cancer patients in India.Method: This was a cross-sectional and observational study, conducted over 111 breast cancer patients in a tertiary cancer hospital, Kolkata. Subjects were eligible to participate and they were of over 23rd years of age and had a histologically confirmed diagnosis of breast cancer had no history of recurrence or metastasis, and had no previous psychological problems. Age, marital status, residence, education, occupation and family income were assesses for patients’ socio economic status. Psychological symptoms and quality of life were assessed by using validated tools. Means and standard deviations of each outcome were compared by socioeconomic status and multivariate linear regression models for evaluating the association between socioeconomic status, psychological distress and quality of lifeResults: The patient group was categorized into three groups based on their income level as follows: ≤500=27.9%), 500-1000=51.4% and high income = ≥1000=20.7%. A total of 111 breast cancer patients participated in the study; the mean age of participants was 49.7 (SE=1.31).After using multivariate logistic regression with fully adjusted models, the patients who were living alone had significantly higher level of depression and poor quality of life compared to those who are employed. Higher education and family income both positively associated with quality of life after adjusting for age, marital status and occupation.Conclusion: The findings revealed that the family income have a significant impact on the psychological distress of the cancer patients.

Distribution of virulence factors and its relatedness towards the antimicrobial response of enterotoxigenic Escherichia coli strains isolated from patients in Kolkata, India.

Enterotoxigenic Escherichia coli (ETEC) is one of the most widely recognized diarrhoeal pathogens in developing countries. The advancement of ETEC vaccine development depends on the antigenic determinants of the ETEC isolates from a particular geographical region. So, the aim here was to comprehend the distribution of virulence determinants of the clinical ETEC strains of this region. Additionally, an attempt was made to find any correlation with the antimicrobial response pattern. Multiplex PCR was employed to identify virulence determinants followed by confirmatory singleplex PCR. For observation of antibiotic response, the Kirby-Bauer method was used. Out of 379strains, 46% of strains harboured both the enterotoxins ST and LT, whereas 15% were LT only. Among the major colonization factors (CFs), CS6 (41%) was the most prevalent followed by CFA/I (35%) and CFA/III was the lowest (3%). Among the minor CFs, CS21 (25%) was most prevalent, while CS15showed the lowest (3%) presence. Among the non-classical virulence factors, EatA (69%) was predominant. ETEC strains harbouring CS6showed resistance towards the commonly used drug Ciprofloxacin (70%). CS6 and elt+est toxin genes co-occurred covering 51% of the isolates. CS21 was found in most strains with est genes (43%). EatA was found to occur frequently when ST was present alone or with LT. CS6-harbouring strains showed an independent correlation to antimicrobial resistance. This study would aid in identifying the commonly circulating ETEC isolates of Kolkata, India, and their prevalent virulence determinants. Knowledge of antibiotic resistance patterns would also help in the appropriate use of antibiotics. Furthermore, the study would aid in identifying the multivalent antigens suitable for region-specific ETEC vaccines with maximum coverage.

Genomic Surveillance and Phylodynamic Analyses Reveal the Emergence of Novel Mutations and Co-mutation Patterns Within SARS-CoV-2 Variants Prevalent in India.

Identification of the genomic diversity and the phylodynamic profiles of prevalent variants is critical to understand the evolution and spread of SARS-CoV-2 variants. We performed whole-genome sequencing of 54 SARS-CoV-2 variants collected from COVID-19 patients in Kolkata, West Bengal during August–October 2020. Phylogeographic and phylodynamic analyses were performed using these 54 and other sequences from India and abroad that are available in the GISAID database. We estimated the clade dynamics of the Indian variants and compared the clade-specific mutations and the co-mutation patterns across states and union territories of India over the time course. Frequent mutations and co-mutations observed within the major clades across time periods do not show much overlap, indicating the emergence of newer mutations in the viral population prevailing in the country. Furthermore, we explored the possible association of specific mutations and co-mutations with the infection outcomes manifested in Indian patients.

Barriers, Facilitators and Recommended Strategies for Implementing a Home-Based Palliative Care Intervention in Kolkata, India.

40 million people in the world are in need of palliative care, but only one-seventh of that population receive services. Underuse of palliative care in low resource countries exacerbates suffering in patients with life limiting illnesses such as cancer. The current study was conducted to identify barriers, facilitators and recommended strategies for informing development of a home-based palliative care intervention for poor and medically underserved rural patients in Kolkata, India. Semi-structured interviews were conducted with 20 clinical and patient stakeholders in Kolkata, India. Questions queried current practices for delivering palliative care, along with barriers, facilitators and optimal strategies for implementing homebased palliative care. We identified some key barriers to palliative care delivery in rural areas: lack of access to palliative care till late stages; patients unaware of their cancer stage; lack of affordability of medication and treatment costs; transportation challenges to access care; strict morphine distribution regulations making it challenging for patients to obtain morphine; cultural factors discouraging patients from seeking palliative care; resistance from medical community to use "rural medical practitioners (RMPs)" to deliver care. We also identified important facilitators, including availability of existing palliative care infrastructure at the cancer center, network of RMPs to serve as CHWs to facilitate palliative care delivery, low morphine cost and family support system for patients. Our findings provide evidence that a palliative care intervention which leverages an existing CHW infrastructure may be a feasible model for expanding the reach of palliative care to rural underserved patients.

AN EPIDEMIOLOGICAL STUDY ON PRAMEHA (DIABETES MELLITUS) IN KOLKATA

Type 2 diabetes mellitus is one of the most leading causes of death and disability worldwide among the lifestyle disorders where dietary and lifestyle factors play a major role. Prameha is a classical metabolic disorder of tissue and cellular level. Unhealthy diet and physical inactivity are the leading causes of the lifestyle disorders; Prameha is also among them as mentioned by Acharya Charaka. A survey study was carried out to study the prevalence of Prameha patients and associated risk factors in the light of epidemiological aspect. 120 diabetic patients from OPD of Institute of Post Graduate Ayurvedic Education and Research, Kolkata, were selected randomly according to their registered address as residents of Kolkata. A survey proforma along with consent form was prepared and detailed history of each patient fulfilling the subjective criteria of Prameha and objective criteria of Diabetes Mellitus were taken. On considering data of Santarpana nidana, maximum patients were taking excess carbohydrate (90%); dairy products (82.5%); fried and fatty diet (68.33%); sweets and sugarcane preparations (79.16%); junk and fast foods (82.5%) in excessive quantity and 51.66% patient were found to be with increased BMI. Factors observed related to lifestyle are Divaswapna (60%) and Asyasukham (65%). Udvega (stress) were found in 88.33% of patients. This study revealed that prevalence of carbohydrate rich diet; dairy products; junk food and increased BMI are found dominant in diabetes patients in Kolkata. Avoidance of these faulty dietary habits and sedentary lifestyle, further progression of the diabetes along with its complications can be inhibited.

Altered Integrative and Conjugative Elements (ICEs) in Recent Vibrio cholerae O1 Isolated From Cholera Cases, Kolkata, India.

The self-transferring integrative and conjugative elements (ICEs) are large genomic segments carrying several bacterial adaptive functions including antimicrobial resistance (AMR). SXT/R391 family is one of the ICEs extensively studied in cholera-causing pathogen Vibrio cholerae. The genetic characteristics of ICE-SXT/R391 in V. cholerae are dynamic and region-specific. These ICEs in V. cholerae are strongly correlated with resistance to several antibiotics such as tetracycline, streptomycin and trimethoprim-sulfamethoxazole. We screened V. cholerae O1 strains isolated from cholera patients in Kolkata, India from 2008 to 2015 for antibiotic susceptibility and the presence of ICEs, and subsequently sequenced their conserved genes. Resistance to tetracycline, streptomycin and trimethoprim-sulfamethoxazole was detected in strains isolated during 2008–2010 and 2014–2015. The genes encoding resistance to tetracycline (tetA), trimethoprim-sulfamethoxazole (dfrA1 and sul2), streptomycin (strAB), and chloramphenicol (floR) were detected in the ICEs of these strains. There was a decrease in overall drug resistance in V. cholerae associated with the ICEs in 2011. DNA sequence analysis also showed that AMR in these strains was conferred mainly by two types of ICEs, i.e., ICETET (comprising tetA, strAB, sul2, and dfrA1) and ICEGEN (floR, strAB, sul2, and dfrA1). Based on the genetic structure, Kolkata strains of V. cholerae O1 had distinct genetic traits different from the ICEs reported in other cholera endemic regions. Transfer of AMR was confirmed by conjugation with sodium azide resistant Escherichia coli J53. In addition to the acquired resistance to streptomycin and trimethoprim-sulfamethoxazole, the conjugally transferred (CT) E. coli J53 with ICE showed higher resistance to chloramphenicol and tetracycline than the donor V. cholerae. Pulsed-field gel electrophoresis (PFGE) based clonal analysis revealed that the V. cholerae strains could be grouped based on their ICEs and AMR patterns. Our findings demonstrate the epidemiological importance of ICEs and their role in the emergence of multidrug resistance (MDR) in El Tor vibrios.

Emergence of Azithromycin Resistance Mediated by Phosphotransferase-Encoding mph(A) in Diarrheagenic Vibrio fluvialis.

The azithromycin resistance conferred by phosphotransferase is encoded in the gene mph(A). This gene has been discovered in and reported for many bacterial species. We examined the prevalence of azithromycin resistance in Vibrio fluvialis (AR-VF) isolated during 2014 to 2015 from the hospitalized acute diarrheal patients in Kolkata, India. Most of the V. fluvialis isolates are identified as the sole pathogen (54%). The prevalence of AR-VF was higher in 2015 (19 [68%]) than in 2014 (9 [32%]). Among AR-VF isolates, the azithromycin MICs ranged from 4 to >256 mg/liter. Twenty-eight of the 48 (58%) V. fluvialis isolates harbored the gene mph(A) and phenotypically resistant to azithromycin. All the AR-VF isolates remained susceptible to doxycycline. In addition to azithromycin, other antimicrobial resistance-encoding genes of AR-VF were also characterized. All the AR-VF isolates were positive for class 1 integron, and most of them (17/28) carried the dfrA1 gene cassettes. Only one isolate was positive for the ereA gene, which encodes resistance to erythomycin. The majority of the isolates were resistant to β-lactam antibiotics (blaOXA-1 [96%], blaOXA-7 [93%], and blaTEM-9 [68%]) and aminoglycoside actetyltransferase, conferring resistance to ciprofloxacin-modifying enzyme [aac(6')Ib-cr] (96%). Analyses by pulsed-field gel electrophoresis (PFGE) showed that the AR-VF isolates belonged to different genetic lineages. This is the first study to report azithromycin resistance and the presence of the mph(A) gene in V. fluvialis isolates. Circulation of AR-VF isolates with high azithromycin MICs is worrisome, since it may limit the treatment options for diarrheal infections.IMPORTANCE The progressive rise in antibiotic resistance among enteric pathogens in developing countries is becoming a big concern. India is one of the largest consumers of antibiotics, and their use is not well regulated. V. fluvialis is increasingly recognized as an emerging diarrheal pathogen of public health importance. Here we report the emergence of azithromycin resistance in V. fluvialis isolates from diarrheal patients in Kolkata, India. Azithromycin has been widely used in the treatment of various infections, both in children and in adults. Resistance to azithromycin is encoded in the gene mph(A). Emerging azithromycin resistance in V. fluvialis is a major public health challenge, and future studies should be focused on identifying ways to prevent the dissemination of this antibiotic resistance gene.

Identification of common virulence factors present in enterotoxigenic Escherichia coli isolated from diarrhoeal patients in Kolkata, India.

Development of an effective vaccine against enterotoxigenic Escherichia coli (ETEC) is largely dependent on the conscientious understanding of different virulence associated factors from diverse geographical areas. So, the objective of this study is to elucidate the distribution of enterotoxins, CF and NCVF in clinical ETEC strains isolated between 2008 and 2014 from two hospitals in Kolkata, India. Multiplex PCR method was used for detection of two enterotoxin genes, 11 common CFs and five common NCVFs. Among the 350 tested ETEC strains, 61% strains possessed est+elt genes, 25% est and 14% elt. Among 56% CF positive ETEC strains, CS21 was the prevalent one (37%) followed by CS6 (36%). NCVF genes were present in 59% of the ETEC strains; eatA was the most prevalent (65%) followed by etpA (51%). There were 29% strains negative for any CFs or NCVFs. We conclude that a pattern exists between CS6, eatA and toxins. We observed est with or without elt, CS6 with or without CS5 and with or without eatA were present in 24% of clinical ETEC strains (59/250) analysed. CS21 has emerged as another predominant CF but it had diverse CFs and NCVFs. Prevalence of ETEC virulence factors would help in tracking ETEC globally and suggests the need of a multivalent ETEC vaccine.

The Impact of Socioeconomic Status on the Psychological Distress of Breast Cancer Patients in Kolkata"

Background: Breast cancer patients experience a variety of psychological symptoms such as anxiety, depression that affect their quality of life. The present study probed whether the socioeconomic status had any significance on psychological distress and quality of life of breast cancer patients in India. Method: This was a cross-sectional and observational study, conducted over 111 breast cancer patients in a tertiary cancer hospital, Kolkata. Subjects were eligible to participate and they were of over 23rd years of age and had a histologically confirmed diagnosis of breast cancer had no history of recurrence or metastasis, and had no previous psychological problems. Age, marital status, residence, education, occupation and family income were assesses for patients’ socio economic status. Psychological symptoms and quality of life were assessed by using validated tools. Means and standard deviations of each outcome were compared by socioeconomic status and multivariate linear regression models for evaluating the association between socioeconomic status, psychological distress and quality of lifeResults: The patient group was categorized into three groups based on their income level as follows: ≤500=27.9%), 500-1000=51.4% and high income = ≥1000=20.7%. A total of 111 breast cancer patients participated in the study; the mean age of participants was 49.7 (SE=1.31). After using multivariate logistic regression with fully adjusted models, the patients who were living alone had significantly higher level of depression and poor quality of life compared to those who are employed. Higher education and family income both positively associated with quality of life after adjusting for age, marital status and occupation. Conclusion: The findings revealed that the family income have a significant impact on the psychological distress of the cancer patients.

A study on the evaluation of bite force, prosthetic and nutritional status in adult cleft patients in Kolkata.

Context:Altered orofacial morphology and poor dental status affects the dietary intake of cleft patient, making susceptible to nutritional imbalance. Oral health care planning for this population is impossible without the evaluation of stomatognathic functional status as well as prosthetic and nutritional status and need.Aims:The aim of this study was to evaluate prosthetic status and prosthetic treatment need, bite force and nutritional status, in adult cleft patients and to compare them with the adult noncleft population of similar definition.Settings and Design:Cleft (n = 250) and noncleft (n = 250) individuals of either sex, aged 18 years or above, excluding severe medically compromised and differently abled, were examined and individual biteforce was measured after obtaining written consent and ethical clearance from the two institutions in Kolkata.Subjects and Methods:A “raw data sheet” was prepared according to the parameters of the “Oral Health Surveys: Basic methods,” World Health Organization (1997) for evaluation of prosthetic status and need, dentition status and Mini-Nutritional Assessment, Nestlé (1994) for the evaluation nutritional status. A Gnathodynamometer was used to record bite force.Statistical Analysis Used:Statistical analysis was performed using SPSS 20.0.1, Graph Pad Prism version 5, Student's t-test, and Chi-square test.Results:The mean bite force of frontal area in cleft group (3.4356 ± 0.9457 kgf) was found to be significantly lower (P < 0.0001) than in noncleft (22.8749 ± 5.3644 kgf) group. The difference of mean bite force in the right side (2.4576 ± 0.6131 kgf) and left side (1.2708 ± 0.1036 kgf) in cleft group was found to be statistically significant (P < 0.0001). Prosthetic need in maxillary arch was found to be significantly (χ2: 490.0000; P < 0.0001) higher in cleft than in noncleft group. Nutritional status was observed to be significantly (χ2: 179.4049; P < 0.0001) higher “at risk” in cleft than in noncleft group.Conclusions:Lack of adequate Government concern leading to significantly higher prosthetic need and lower prosthetic status, hence lower bite force resulting lower nutritional status in adult cleft patients in Kolkata.
