Bilateral ovarian serous cystadenocarcinoma in a teenager: a case report.
(2019) Ajani, T. A.; Oluwasola, T. A. O.; Anaedobe, C. G.; Ajani, M. A.; Fayemiwo, S. A.; Bakare, R. A.
Epithelial ovarian cancers are uncommon among young girls and teenagers compared to germ cell tumors. We report a case of bilateral ovarian serous cystadenocarcinoma in a teenage girl with the attendant challenges of diagnosis, management and follow up. HT, 19 year old had presented at a secondary care level with features suggestive of benign ovarian tumor and had ovariectomy done. However, histology report revealed a malignant epithelial cancer, necessitating a repeat exploration. She was found to have surgical stage 3c disease and subsequently has total abdominal hysterectomy with bilateral salpingectomies, right oophorectomy and omentectomy. She was further managed with paclitaxel-carboplatin combination chemotherapy but defaulted after the 3rd cycle on account of financial constraints. She succumbed to the disease 11 months post diagnosis. Though uncommon, detailed evaluation of teenage patients for malignant ovarian cancer is expedient. The financial burden of cancer care in our environment is also highlighted.

(Sage, 2014) Kuti, M. A.; Adesina, O. A.; Awolude, O. A.; Ogunbosi, B. O.; Fayemiwo, S. A.; Akinyemi, J. O.; Adetunji, A. A.; Irabor, A. E.; Odaibo, G. N.; Prosper, O.; Taiwo, B. O.; Olaleye, D.; Murphy, R. L.; Kanki, P.; Adewole, I. F.
Aims: This study aimed to describe the prevalence and pattern of lipid abnormalities among antiretroviral therapy (ART)- naive HIV patients, understand if there is any relationship to virologic and immunologic status, and discuss the implications for care. Methods: This was a cross-sectional study in which baseline demographic, clinical, and laboratory data of all ART-naive HIV-infected individuals recruited into the adult ARV clinic, University College Hospital, Ibadan, between January and December 2006, were analyzed. Results: In total, 1316 ART-naive HIV-infected persons were recruited in the period. Females subjects and participants aged 35 years accounted for 67.1% and 57.7% of all participants, respectively. At least 1 abnormal lipid fraction was seen in 73.3% of participants. It was observed that in 11.5% participants the total cholesterol (TC) was ≥5.2 mmol/L, in 2.7% the low-density lipoprotein cholesterol (LDL)-C was >4.1 mmol/L in 56.5% the high-density lipoprotein cholesterol (HDL)-C was <1.0 mmol/L, and in 27.6% the triglyceride (TG) was >1.7 mmol/L. The TC, LDL-C, and HDL-C were all significantly positively correlated with CD4 counts and negatively correlated with viral load. On the contrary, the TG levels were negatively correlated with CD4 counts and positively correlated with viral load. Multivariate linear analysis showed a significant relationship between all the lipid parameters and viral load. CD4 counts were only significantly associated with TC. Conclusions: A significant burden of dyslipidemia exists among ART-naive HIV-infected persons. Low HDL-C was the most frequently observed abnormality. The abnormalities related more with viral load levels than with CD4 counts. Dyslipidemia screening should be done in ART-naive HIV-infected persons. Simple healthy lifestyle changes should be emphasized, with other care given to those with the disorder.

(Society for Gastroenterology and Hepatology in Nigeria (SOGHIN), 2016) Adesina, O. A.; Akinyemi, J. O.; Michael, O. S.; Fayemiwo, S. A.; Awolude, O. A.; Ogunbosi, B. O.; Kuti, M. A.; Adewole, I. F.
Background and Objectives: Both hepatitis C and Human Immunodeficiency viruses affect laboratory indices. The objective of this study was to describe the impact of both viruses on laboratory indices among 1,821 HIV-positive pregnant women. Methods: This was a cross-sectional retrospective study at the University College Hospital, Ibadan Results: Twenty-six (1.7%) women were HCV positive, 139 (8.8%) were HBsAg positive and 1, 407 (89.3%) were negative for both viruses. Three patients (0.19%) were positive for both viruses. These patients, the HBsAg positive women and 246 with no result for either virus were excluded from analysis. The HCV positive women had lower hematocrit (27.3% + 4.5 vs. 28.4% + 4.6, p=0.29), lower WBC (5, 200 vs. 5, 500 cells/ml, p =0.766) but higher platelet count (209, 000 vs. 199, 000 cells / ml, p = 0.019). The coinfected group had higher CD4 (380 vs. 326 cells/ml, p = 0.319), higher urea (16.0vs.ll.0mg/ml, p =0.013) but comparable ALT (16.0 vs.15.0 iu/ml, p = 0.95), log viral load (4.08+1.22 vs. 4.08+1.11, p=0.97) and creatinine levels (0.6vs.0.6, p=0.329). Only the difference in urea level was statistically significant. Conclusion: While values were comparable between both groups, the synergistic effect of both viruses makes it necessary for health-care providers to closely monitor patients.
External genital warts in HIV-infected patients with sexually transmitted infections in Ibadan, Nigeria
(2017) Fayemiwo, S. A.; Adesina, O. A.; Akinyemi, J. O.; Michael, O. S.; Adekanmbi, O. A.; Awolude, O. A.; Kuti, M. A.; Odaibo, G. N.; Adewole, I. F.
Background: Human Papilloma Virus (HPV) infection in the genital area is usually asymptomatic, and when symptomatic, manifests in cither benign or malignant forms. This study aims at providing information on the prevalence of external genital warts (EGWs) among people living with HIV (PLWHIVs) attending Antiretroviral Treatment (ART) clinic at the University College Hospital. Ibadan, Nigeria. Methods: This is a descriptive cross-sectional survey of PLWHIVs attending ART clinic between January 2006 and December 2007. Diagnosis of genital warts was based on the findings of typical lesions on the external genitalia, vaginal, cervix or perianal region after clinical examination and informed consent from each participant. Antibodies against Herpes and HPV were measured using, Enzyme-linked immunosorbent Assay (ELISA). Results: A total of 5.207 patients, 3519 female and 1688 males attended the ART clinic during the period. The mean age of the patients was 34,67 yrs (± 9.16). Five hundred and forty-two (10.0%) had various sexually transmitted infections (STIs). The prevalence of anogenital warts was 3.65% among the HIV-infected patients and 35.0 % among the subset of HIV- infected patients with STIs. The prevalence of genital warts was 1.5 times higher in treatment experienced patients (OR =1.46; 95%CI: 1.02,2.10). Genital wart was found to be associated with low CD4 count, high viral load, treatment- experience and non-use of condom during sexual intercourse. (P = 0.002). Conclusions: External genital warts are common among people living with HIV infection. According to the appropriate guidelines, HPV vaccine should also be offered to HIV-infectcd adolescents that are non-rcactivc to the virus.
Genital ulcer diseases among HIV_infected female commercial sex workers in Ibadan, Nigeria
(2011) Fayemiwo, S. A.; Odaibo, G. N.; Oni, A. A.; Ajayi, A. A. A
We evaluated the prevalence and association of Genital Ulcer Diseases (GUDs) among HIV-1 infected female commercial sex workers (FCSWs) in Ibadan, Nigeria. A total of 250 FCSWs from brothels in Ibadan were tested for presence of antibodies to HIV and Syphilis. Pelvic examinations for signs of sexually transmitted infections (STIs) were carried out on the subjects. Endocervical and high vaginal swabs were collected from each of the subjects to establish laboratory diagnosis of STIs. Their age ranged from 15 to 55 years (Mean = 25.8 yrs; SD = 3.74). Majority (246/250) were Nigerians, while 1.6% were from neighboring West African countries. Sixty four (25.6%) of the subjects were positive for HIV-1 while seven (2.8%) had dual HIV-1/2 infection. Analysis of the STIs showed that 49 (19.6%) of the CSWs had GUDs. Herpes genitalis was the commonest GUDs as it occurred in 25 (10%) of the subjects. Other STIs identified were chancroid (5.6%), syphilis (4.0%) and lymphogranuloma venerum (LGV) (4%). Sixteen (64.0%) of the CSWs with herpes genitalis had HIV-1 infection. The risk ratio of herpes genitalis for HIV acquisition was 3.0 (95% CI: 2.0 - 4.4). Syphilis and chancroid were also found tobe significantly associated with increased risk of HIV infection (p < 0.0001). The adjusted odd ratios for Herpes genitalis, chancroid, and syphilis were 3.7 (1-13.0, p < 0.05), 19.8 (2.7-13.0, p < 0.05) and 19.1 (1-231.0, p < 0.05) respectively. There is need to educate FCSWs continually to adopt safer sexual behaviours, seek early diagnosis and treatment of GUDs to reduce their risk of transmitting HIV infection.
Internal and external quality control in the medical microbiology laboratory
(African Society for Clinical and Experimental Microbiology, 2018) Fowotade, A.; Fayemiwo, S. A.; Bongomin, F.; Fasuyi, T. O.; Aigbovo, O. A.; Adegboro, B.
Culture media play a very important role in bacteriology as they are used in the isolation, identification and antimicrobial susceptibility testing. It is essential that the quality of media be safeguarded to have a successful microbiology laboratory. Microorganisms usually show typical morphological appearance and properties on solid media. Variations in the composition of the medium may alter this appearance and properties. There is therefore a need to ensure good quality media, which is capable of giving satisfactory results by ensuring a proper quality management system. Often times, majority of laboratories prepare their media for routine diagnostics and research purposes. Therefore, it is essential that certain parameters of media are checked thoroughly before they are considered suitable for laboratory use. Control methods are discussed in details in this report.
Molluscum contagiosum virus infection among PLWHA In Ibadan, Nigeria
(African Journal of Clinical and Experimental Microbiology, 2014) Fayemiwo, S. A.; Adesina, O. A.; Akinyemi, J. O.; Odaibo, G. N.; Omikunle, T. O.; Adewole, I. F.
Background: Molluscum contagiosum (MC) infection is caused by a pox virus and the virus is probably passed on by direct skin-to- skin contact which may affect any part of the body. There is anecdotal evidence associating facial lesions with HIV-related immunodeficiency. This study was aimed to determine the prevalence and associated risk factors of Molluscum contagiosum infection among PLWHAs attending ART clinic at the University College Hospital, Ibadan, Nigeria. Methods: This is a descriptive cross-sectional survey of 5,207 patients (3519 female and 1688 males) attending ART clinic between January 2006 and December 2007. Physicians performed complete physical and pelvic examinations. Diagnosis of Molluscum Contagiosum infection was based on the clinical findings of typical lesions on the external genitalia, perianal, trunk, abdominal and facial regions. Results: The mean age of the patients was 34.67 yrs. ± 9.16). About 10% (542) had various sexually transmitted infections (STIs). The male to female ratio was 1: 4.2. One hundred and twenty seven subjects (23.4%) had no formal or primary education with 247 (45.6 %) being treatment naive while 295 (54.4 %) were treatment experienced. Of the 542 PLWHAs with STIs, 3.3 % had undetectable viral load (< 200 copies/ ml) while 272 (50.1 %) had low CD4 count (< 200 cells / mm3.) and The Mean log10 viral load was 5.02 ± 0.94. Molluscum Contagiosum infection was diagnosed in 13 patients (0.024%; 8 females and 5 males). Vaginal Candidiasis was the commonest genital infection diagnosed in 223 (41.1%) of the patients with STIs. MC patients had higher viral load, lower CD4 count and more likely to be treatment experienced”. Conclusions: Molluscum Contagiosum infection is not uncommon among the HIV-infected patients, but underreported. Awareness of this cutaneous manifestation should be known to Physicians in AIDS care.
Noscomial Acinetobacter infections in intensive care unit
(Science Publications, 2013) Nwadike, V. U.; Fayemiwo, S. A.; Fowotade, A.; Bakare, R. A.; Olusanya, O.
Acinetobacter plays an important role in the infection of patients admitted to hospitals. Acinetobacter are free living gram-negative coccobacilli that emerge as significant nosocomial pathogens in the hospital setting and are responsible for intermittent outbreaks in the Intensive Care Unit. The aim of this study was to determine the prevalence of Acinetobacter in patients admitted into the Intensive Care Unit and determine their role in infections in the ICU. A total of one hundred patients were recruited for the study, catheter specimen urine, tracheal aspirate and blood culture were collected aseptically from the patients. The specimens were cultured on blood and MacConkey and the organisms identified using Microbact 12E (0xoid). The Plasmid analysis was done using the TENS miniprep method. Fourteen (14%) of the 100 patients recruited into the study, developed Acinetobacter infection. Acinetobacter spp constituted 9% of the total number of isolates. Twelve (86%) of the isolates were recovered from tracheal aspirate, 1(7%) from urine and 1(7%) from blood. All of the isolates harbor plasmids of varying molecular sizes. Ten of the fourteen Acinetobacter were isolated at about the same period of time in the ICU with 6(42.7%) having plasmid size in the 23.1kb band and all showed similar pattern revealing that the isolates exhibit some relatedness. The clonal nature of the isolates suggest that strict infection control practices must be adopted in ICU, also an antibiotic policy must be developed for the ICU to prevent abuse of antibiotics that may lead to selection of resistant bacteria.
Obstetric and newborn outcomes and risk factors for low birth weight and preterm delivery among HIV-infected pregnant women at the University College Hospital Ibadan
(Society of Gynaecology and Obstetrics of Nigeria, 2015-04) Adesina, O. A.; Michael, O. S.; Ogunbosi, B. O.; Akinyemi, J. O.; Kuti, M. A.; Awolude, O. A.; Fayemiwo, S. A.; Adewole, I. F.
There remains uncertainty about the impact of HIV on pregnancy outcomes and effects of highly active antiretroviral therapy on fetal development. This study describes obstetric outcomes among HIV positive parturients at the University College Hospital, Ibadan. HTV positive parturients were identified in the birth register. During the 30-month period, 318 of 6203 deliveries were HIV positive (5.1%) with 97.6% record retrieval. The mean age of the HTV positive parturients was 31.66 years (± 4.66); the mean gestational age at delivery was 38.02 weeks (± 2.75) and the mean birth weight 2.85kg (±0.59). There were 35.8% (109) preterm births, 2.9% stillbirths and 21.5% low birth weights. The regimen most commonly (198, 64.5%) used was a non-nucleoside reverse transcriptase (NNRTI) based HAART. Preterm births were similar following spontaneous vaginal delivery (31.5%) and elective section (31%) but higher (41.3%) with emergency section (p=0.4). On univariate analysis, the preterm infants had lower mean birth weights (2.46±0.61 vs 2.96±0.44; p=0.000). The proportion of preterm births was higher among Low birth weight infants (71.9% vs 28.1%; p=0.00). Variables with more preterm births were age >35 years (51.6%), ≤ 6years of schooling (51.5% vs 48.4%) and being on combination ARV (PI, 37.5% or non-PI, 36.2%). However, these differences did not attain statistical significance. Low birth weight infants had mothers who had higher mean ages (33.28 years ±4.59 vs 31.28 years ± 4.59,. p= 0.02), lower mean gestational age at delivery (35.72 weeks ± 3.16 vs 38.49 weeks ±2.1, p= 0.00). Variables with more low birth weight include <12years of schooling and being on mono/ dual therapy (31.8%). These differences were not statistically significant. On logistic regression, factors that retained an association with low birth weight were mean maternal age at delivery (p= 0.002; β- 0.904; 95% CI, 0.848 - 0.966) and being on mono/ dual therapy (p= 0.039; β= 3.042; 95% CI, 1.055 - 8.768). The only factor that retained an association with preterm birth was mean maternal age at delivery (p= 0.015; β= 0.935; 95% CI, 0.886-0.987). HIV positive (especially older) women, have high rates of preterm deliveries and low birth weights. The beneficial effects of HAART on mother-to-child transmission are indisputable but monitoring antiretroviral therapy in pregnancy remains a priority and antenatal surveillance should include fetal growth assessment.

(MEDIMOND, 2004) Fayemiwo, S. A.; Bakare, R. A.; Odaibo, G. N.; Oni, A. A.; Fasina, A. A.; Olaleye, D. O.; Sankale, J. L.; Kanki, P.
"This study evaluatcd the association of HXV-1 infection with some other sexually transmitted diseases (STDs) among fernaIe commercial sex workers. BIood samples were collected from 250 female commercial sex workers in Ibadan Oyo State, Nigeria and tested for the presence of HEV antibodies using ELISA and Western blot. Endocervical and high vaginal swab samples were also collected for microscopy and culture. The prevalence of HIV- 1 infection among CSWs in Ibadan, Nigeria was 25.6% with 2.8% having dual reactivity to HIV- 1 and HIV- 2. Bacterial vaginosis was the commonest STDs (32.8%) followed by herpes genitalis, vaginal candidiasis, gonorrhoea, trichornoniasis, chancroid,syphilis, tinea curiz, genital warts, Iympholgranuloma venerum (LGV) and scabics. Recurrcnt vaginal discharge, gcnital ulccr discascs as well as non-genital ulcer diseases (tinea curiz and scabies) were associated with increased risk of HIV infections. Access to prevention and prompt management of these STDs will reduce the spread of HIV."
Pattern of asymptomatic sexually transmitted infections in women undergoing hysterosalpingography for infertility evaluation in Ibadan Nigeria
(Society of Gynaecology and Obstetrics of Nigeria (SOGON)., 2013) Atalabi, O. M.; Fayemiwo, S. A.; Oladokun, A. A.; Bakare, R. A.
"The roles of gonorrhea and non-gonococcal urethritis due to Chlamydia trachomatis in the etiology of infertility due to tubal occlusion have been established by various studies. Hysterosalphingography WSG) is done to investigate tubal patency. This study was aimed at finding the prevalence of asymptomatic sexually transmitted infections (STIs) in women being investigated for infertility in a tertiary institution.Methods: This was a cross-sectional study of asymptomatic infertile women referred for pre-HSG screening. Detailed medical history, Endocervical and high vaginal swabs were collected to establish diagnosis of STIs following clinical examination and informed consent. These specimens were evaluated microscopically for Chlamydia trachomatis and bacterial vaginosis. Endocervical secretions were Gram-stained for intracellular Gram - Negative diplococci and suspected isolates were confirmed as Neisseriagonorrhoeae by standard laboratory methods. Results: There were 250 participants with a mean age of 34.6 years (SD = 5.4, range = 25 -49). The mean age of sexual debut of participants was 21.5 years (SD = 4.3). Fifty-six (22.5%) of the women engaged in oral sex while 53 (2 1.2 %) shared their spouses with other sexual partners. 1 7.7% had previous PID, 43.1% of them has vaginal discharge syndrome. The commonest ST1 was Vulvo- vaginal candidiasis (24.4%) and others were bacterial vaginosis (18.4%), Chlamydia cervicitis ( 17.6% ), trichomoniasis (11.2% ), and gonomhea ( 2.4 % ). Conclusion: The procedure of HSG is invasive and asymptomatic infections in the cervix can be dislodged and propagated by injectionof contrast to the fallopian tubes thus causing tubal blockage. Routine Per -HSG screening for occult STIs is encouraged to avoid iatrogenic Pelvic Inflammatoty Disease "
Polymerase chain reaction versus enzyme-linked immunosorbent assay in detection of Chlamydia trachomatis infection among gynaecological patients in southwestern Nigeria.
(2018) Ajani, T. A. O.; Anaedobe, C. G.; Ajani, M. A.; Fayemiwo, S. A.; Bakare, R. A.
Background: Chlamydia trachomatis (C. trachomatis), is the most common bacterial Sexually Transmitted Infection, a major cause of Pelvic Inflammatory Disease and female infertility. Since C. trachomatis infections are frequently asymptomatic with higher prevalence in developing countries, highly sensitive and affordable methods are desirable for routine screening and diagnosis. This study aimed to evaluate the performance of C. trachomatis-specific IgG antibody by ELISA as a screening tool for C. trachomatis infection, by comparing the performance of ELISA with the gold standard Polymerase Chain Reaction( PCR). Method: In this cross sectional study, we enrolled 150 women attending infertility clinic at Ibadan between January and November, 2015. ELISA for detection of IgG antibodies specific to C. trachomatis major outer membrane protein (MOMP) was performed on the blood samples using third generation indirect Enzyme Linked Immunosorbent Assay (ELISA) and endocervical samples were analyzed for presence of C. trachomatis nucleic acid using PCR. Socio demographic bio-data and gynaecological history were obtained with questionnaire; data was analyzed using SPSS version 20.0. Results: Overall, 58 (38.7%) were positive for C. trachomatis specific IgG antibody by ELISA and 11 (7.3%) for C. trachomatis nucleic acid by PCR. Using PCR as the gold standard, ELISA had a sensitivity of 81.8% specificity of 64.8%, positive predictive value of 15.5% negative predictive value of 97.8% and accuracy of 66%. Conclusion: The high sensitivity of the ELISA indicates that over 80% of patients identified as being positive in the screened population are truly infected. Also, the negative predictive value approaches 100% amongst those screened out as being negative. Thus its use as a screening tool for C. trachomatis infection is warranted particularly in developing countries where cheaper and easier to use alternatives to PCR are in dire need.
Rapid HIV Antigen–Antibody Assays and detection of acute HIV infection in sub-saharan Africa
(American Society of Tropical Medicine and Hygiene, 2019) Adetunji, A. A.; Adewumi, M. O.; Michael, O. S.; Fayemiwo, S. A.; Ogunniyi, A.; Taiwo, B. O.
Detection of acute HIV infection is a unique problem that fourth-generation HIV assays were expected to alleviate. In this commentary, we draw attention to the limitations and challenges with use of currently available rapid antigen–antibody (Ag/Ab) combination tests for detection of acute HIV infection in sub-Saharan Africa. Laboratory-based HIV-1 Ag/Ab immunoassays are complex, requiring specialized equipment and handling that are currently not affordable in many settings in Africa. The point-of-care Ag/Ab platform on the other hand is easier to deploy and potentially more accessible in resource-limited settings. However, available fourth-generation HIV-1 rapid diagnostic tests have demonstrated poor performance characteristics in field studies where non-B subtypes of HIV-1 dominate. The potential for point-of-care HIV-1 Ag/Ab diagnostics to significantly improve detection of acute HIV infection remains yet to be realized in sub-Saharan Africa. Assay platforms need to be optimized to identify local circulating subtypes, and optimal algorithms need to be determined
Risk factors and outcome of Acinetobacter infection in the intensive care unit of a tertiary center in Oyo State, Nigeria
(Academic Journals, 2013) Nwadike, V. U.; Fayemiwo, S. A.; Fowotade, A.; Bakare, R. A.; Olusanya, O. O.
Acinetobacter plays an important role in the infection of patients admitted to hospitals. Acinetobacter are free living gram-negative coccobacilli that emerge as significant nosocomial pathogens in the hospital setting and are responsible for intermittent outbreaks in the intensive care unit. The aim of this study was to determine the risk factors and outcome of Acinetobacter infections in patients admitted into the intensive care unit of a tertiary center in Oyo State, Nigeria. A total of one hundred patients were recruited for the study, catheter specimen urine, tracheal aspirate and blood culture were collected aseptically from the patients. The specimens were cultured on blood and MacConkey and the organisms identified using Microbact 12E (0xoid). Fourteen (14%) of the 100 patients recruited into the study developed Acinetobacter infection. Chronic obstructive pulmonary disease, endotracheal intubation, and duration of endotracheal intubation were associated risk factors with only duration of endotracheal intubation specifically an 8 to 14 day period being an independent risk factor for Acinetobacter. Six of the patients died of the infection while the remaining eight were discharged from the ICU. The findings that chronic obstructive pulmonary disease and duration of endotracheal intubation being associated with Acinetobacter infection and the attendant mortality associated with the infection should draw attention to this seemingly silent epidemic in our Intensive Care Units so that effective surveillance protocols can be deployed to manage this infection whenever it rears its head.
Suicidal behavior and associations with quality of life among HIV/AIDS patients in Ibadan, Nigeria
(SAGE, 2015) Oladeji, B. D.; Taiwo, B.; Mosuro, O.; Fayemiwo, S. A.; Abiona, T.; Fought, A. J.; Robertson, K.; Ogunniyi, A.; Adewole, I. F.
Background: Suicidality has rarely been studied in HIV-infected patients in sub-Saharan Africa. This study explored suicidal behavior in a clinic sample of people living with HIV, in Nigeria. Methods: Consecutive patients were interviewed using the Composite International Diagnostic Interview (CIDI-10.0) and the World Health Organization Quality of Life (WHO-QOLHIV-BREF). Associations of suicidal behavior were explored using logistic regression models. Results: In this sample of 828 patients (71% female, mean age 41.3 + 10 years), prevalence of suicidal behaviors were 15.1%, 5.8%, and 3.9% for suicidal ideation, plans, and attempts, respectively. Women were more likely than men to report suicidal ideation (odds ratio 1.7; 95% confidence interval 1.05-2.64). Depression and/or anxiety disorder was associated with increased odds of all suicidal behaviors. Suicidal behavior was associated with significantly lower overall and domain scores on the WHO-QOL. Conclusion: Suicidal behaviors were common and significantly associated with the presence of mental disorders and lower quality of life.
