RESUMEN

Background@#Respiratory pathogen infections and air pollution are main causes of acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Air pollution has a direct effect on the airway epithelial barrier and the immune system, which can have an influence on infection. However, studies on the relationship between respiratory infections and air pollutants in severe AECOPD are limited. Thus, the objective of this study was to investigate the correlation between air pollution and respiratory pathogen in severe AECOPD. @*Methods@#This multicenter observational study was conducted by reviewing electronic medical records of patients with AECOPD at 28 hospitals in South Korea. Patients were divided into four groups according to the comprehensive air-quality index (CAI) used in Korea. Identification rates of bacteria and viruses of each group were analyzed. @*Results@#Viral pathogens were identified in 270 (36.7%) of 735 patients. Viral identification rate was different (P = 0.012) according to air pollution. Specifically, the virus detection rate was 55.9% in the group of CAI ‘D’ with the highest air pollution. It was 24.4% in the group of CAI ‘A’ with the lowest air pollution. This pattern was clearly seen for influenza virus A (P = 0.042). When further analysis was performed with particulate matter (PM), the higher/lower the PM level, the higher/lower the virus detection rate. However, no significant difference was found in the analysis related to bacteria. @*Conclusion@#Air pollution may make COPD patients more susceptible to respiratory viral infections, especially influenza virus A. Thus, on days with poor air quality, COPD patients need to be more careful about respiratory infections.

RESUMEN

The objective of this study was to compare recommendations of the Korean Medication Algorithm Project for Bipolar Disorder 2022 (KMAP-BP 2022) with other recently published guidelines for treating bipolar disorder. We reviewed a total of six recently published global treatment guidelines and compared treatment recommendation of the KMAP-BP 2022 with those of other guidelines. For initial treatment of mania, there were no significant differences across treatment guidelines. All guidelines recommended mood stabilizer (MS) or atypical antipsychotic (AAP) monotherapy or a combination of an MS with an AAP as a first-line treatment strategy in a same degree for mania. However, the KMAP-BP 2022 recommended MS + AAP combination therapy for psychotic mania, mixed mania and psychotic depression as treatment of choice. Aripiprazole, quetiapine and olanzapine were the first-line AAPs for nearly all phases of bipolar disorder across guidelines. Some guideline suggested olanzapine is a second-line options during maintenance treatment, related to concern about long-term tolerability. Most guidelines advocated newer AAPs (asenapine, cariprazine, long-acting injectable risperidone, and aripiprazole once monthly) as first-line treatment options for all phases while lamotrigine was recommended for depressive and maintenance phases. Lithium and valproic acid were commonly used as MSs in all phases of bipolar disorder. KMAP-BP 2022 guidelines were similar to other guidelines, reflecting current changes in prescription patterns for bipolar disorder based on accumulated research data. Strong preference for combination therapy was characteristic of KMAP-BP 2022, predominantly in the treatment of psychotic mania, mixed mania and psychotic depression.

RESUMEN

Objective@#The Functioning Assessment Short Test (FAST) is a relatively specific test for bipolar disorders designed to assess the main functioning problems experienced by patients. This brief instrument includes 24 items assessing impairment or disability in 6 domains of functioning: autonomy, occupational functioning, cognitive functioning, financial issues, interpersonal relationships, and leisure time. It has already been translated into standardized versions in several languages. The aim of this study is to measure the validity and reliability of the Korean version of FAST (K-FAST). @*Methods@#A total of 209 bipolar disorder patients were recruited from 14 centers in Korea. K-FAST, Young Mania Rating Scale (YMRS), Bipolar Depression Rating Scale (BDRS), Global Assessment of Functioning (GAF) and the World Health Organization Quality of Life Assessment Instrument Brief Form (WHOQOL-BREF) were administered, and psychometric analysis of the K-FAST was conducted. @*Results@#The internal consistency (Cronbach’s alpha) of the K-FAST was 0.95. Test-retest reliability analysis showed a strong correlation between the two measures assessed at a 1-week interval (ICC = 0.97; p < 0.001). The K-FAST exhibited significant correlations with GAF (r = −0.771), WHOQOL-BREF (r = −0.326), YMRS (r = 0.509) and BDRS (r = 0.598). A strong negative correlation with GAF pointed to a reasonable degree of concurrent validity. Although the exploratory factor analysis showed four factors, the confirmatory factor analysis of questionnaires had a good fit for a six factors model (CFI = 0.925; TLI = 0.912; RMSEA = 0.078). @*Conclusion@#The K-FAST has good psychometric properties, good internal consistency, and can be applicable and acceptable to the Korean context.

RESUMEN

Resection margin involvement after curative intent resection for gastric cancer results in a poor prognosis and deprives the patient of the chance for a cure. Reoperation to achieve an R0 status should guarantee tolerable morbidity and achievement of negative margins. We performed laparoscopic distal gastrectomy with extracorporeal Billroth II reconstruction in a 56-year-old woman with gastric cancer following neoadjuvant chemotherapy. Scattered cancer cells were observed in the proximal and distal resection margins on immunohistochemical staining for cytokeratin. Two weeks postoperatively, remnant total gastrectomy and supra-ampullary duodenectomy were performed. Before reoperation, percutaneous transhepatic gallbladder drainage and angiocatheter placement outside the ampulla of Vater (AoV) via the cystic duct were performed to avoid pancreaticoduodenectomy and to obtain the maximal distal margin. Duodenal transection was performed 1 cm above the AoV. The resected duodenum was 4 cm in length. The patient had no postoperative complications and received adjuvant chemotherapy 1 month after the reoperation.

RESUMEN

Purpose@#The number of elderly patients, especially aged ≥80 years, undergoing emergency surgery is gradually increasing. The aim of this study was to find out the trends and results of emergency general surgery for elderly patients over 9 years in an emergency medical center in South Korea, where the population is aging most rapidly. @*Methods@#The clinical characteristics, outcomes, and medical expenses of emergency general surgery for the elderly (aged 65–79 years) and highly elderly (aged ≥80 years) patients who visited to a regional emergency medical center from 2012 to 2020 were analyzed. @*Results@#The number of highly elderly patients increased with each 3-year interval, whereas the proportion of patients aged 19–79 years was similar, and that of pediatric patients was decreasing. The higher the age group, the higher the mortality (young adult vs. elderly vs. highly elderly: odds ratio [OR], 1 vs. 3.689 vs. 11.293; P < 0.001) and complication rates (OR, 1 vs. 2.840 vs. 4.633; P < 0.001), and longer length of hospital stay (β = 0.949, P = 0.001) even after adjusting for the type of surgery and the American Society of Anesthesiologists physical status classification. Non-covered medical expenses were significantly related to the age groups (β = 151,608.802, P < 0.001). @*Conclusion@#The higher age group was associated with increased number of unfavorable outcomes after emergency general surgery, along with increased medical cost. Efforts to prevent emergency surgery for elderly patients and a specialized treatment system are needed.

RESUMEN

Background@#Although respiratory tract infection is one of the most important factors triggering acute exacerbation of chronic obstructive pulmonary disease (AE-COPD), limited data are available to suggest an epidemiologic pattern of microbiology in South Korea. @*Methods@#A multicenter observational study was conducted between January 2015 and December 2018 across 28 hospitals in South Korea. Adult patients with moderate-to-severe acute exacerbations of COPD were eligible to participate in the present study. The participants underwent all conventional tests to identify etiology of microbial pathogenesis. The primary outcome was the percentage of different microbiological pathogens causing AE-COPD. A comparative microbiological analysis of the patients with overlapping asthma–COPD (ACO) and pure COPD was performed. @*Results@#We included 1,186 patients with AE-COPD. Patients with pure COPD constituted 87.9% and those with ACO accounted for 12.1%. Nearly half of the patients used an inhaled corticosteroid-containing regimen and one-fifth used systemic corticosteroids. Respiratory pathogens were found in 55.3% of all such patients. Bacteria and viruses were detected in 33% and 33.2%, respectively. Bacterial and viral coinfections were found in 10.9%. The most frequently detected bacteria were Pseudomonas aeruginosa (9.8%), and the most frequently detected virus was influenza A (10.4%). Multiple bacterial infections were more likely to appear in ACO than in pure COPD (8.3% vs. 3.6%, p=0.016). @*Conclusion@#Distinct microbiological patterns were identified in patients with moderate-to-severe AE-COPD in South Korea. These findings may improve evidence-based management of patients with AE-COPD and represent the basis for further studies investigating infectious pathogens in patients with COPD.

RESUMEN

Background@#The goal of this study is to investigate the relationship between depression and glycated hemoglobin in the general Korean population. @*Methods@#Adults aged 19 to 80 years were surveyed as part of the 2019 Korea National Health and Nutrition Examination Survey. A total of 4,831 people were chosen to complete the health questionnaire, provide their body mass index, and get a HbA1c blood test. The general characteristics of groups with high and low glycated hemoglobin were identified. To find out the correlation between depression diagnosis and the general population with high glycated hemoglobin, a chi-square test was carried out. A t-test was also used to compare the means of glycated hemoglobin between the groups diagnosed with and not diagnosed with depression. In analyzing the relationship between depression and glycated hemoglobin, analysis of covariance was performed by adjusting the effects for demographic factors. @*Results@#Sex, age, income level, education level, drinking, smoking, exercise, and body mass index are all factors that influence glycated hemoglobin. The mean glycated hemoglobin was high in the group diagnosed with depression. The relationship between depression and glycated hemoglobin could not be confirmed using logistic regression after controlling for confounding variables. @*Conclusion@#There was no significant correlation between depression and glycated hemoglobin in the general population of Korea based on the results of this study.

RESUMEN

Pharmacogenetics is used in psychiatry to predict the effects and side effects of psychotropic drugs. As most mental disorders have complex causes and unpredictable outcomes, personalized treatment using pharmacogenomics would be a useful method. However, pharmacogenetic studies in psychiatry have yielded insignificant results thus far, making their clinical application extremely limited. Early testing, prediction of drug side effects, and drug compliance will be discussed as considerations for the effectiveness of the pharmacogenetic test in psychiatry. Although pharmacogenetic tests in psychiatry do not yet have high sensitivity and specificity, they may be useful in the future for predicting clinical prognosis or developing novel drug treatments. As a result, the authors summarized the current state and prospects of pharmacogenetics in psychiatry in this review.

RESUMEN

Purpose@#We investigated the relationship between nocturia and mortality risk in the United States. @*Methods@#Data were obtained from the National Health and Nutrition Examination Survey 2005–2010. Mortality data were obtained by linking the primary database to death certificate data found in the National Death Index with mortality follow-up up to December 31, 2015. Nocturia was defined based on symptoms reported in the symptom questionnaire. We categorized patients into 2 groups: mild nocturia (2–3 voidsight) and moderate-to severe nocturia (≥4 voidsight). Multiple Cox regression analyses were performed with adjustment for confounding variables at the baseline survey. @*Results@#This study included 9,892 adults (4,758 men, 5,134 women). Nocturia occurred in 3,314 individuals (33.5%). Nocturia was significantly associated with all-cause mortality (hazard ratio [HR], 1.23; 95% confidence interval [CI], 1.10–1.39) and cardiovascular disease (CVD) mortality (HR, 1.55; 95% CI, 1.19–2.01). Moreover, the mortality risk increased with increasing nocturia severity. Further analysis with propensity score matching showed that nocturia was still significantly associated with all-cause mortality and CVD mortality. In subgroup analysis according to sex, nocturia was significantly associated with allcause mortality and CVD mortality in men. In women, moderate-to-severe nocturia was significantly associated with allcause mortality and CVD mortality. In subgroup analysis according to cardio-metabolic diseases, nocturia was associated with CVD mortality in patients with diabetes mellitus, hypertension, dyslipidemia, or CVD at baseline. In subgroup analysis of patients without diabetes mellitus, hypertension or CVD, nocturia was significantly associated with all-cause mortality. @*Conclusions@#Nocturia was significantly associated with mortality in men and women after adjusting for major confounding factors.

RESUMEN

Objectives@#The pharmacotherapy of bipolar disorder is complex. A treatment guideline or algorithm can help clinicians implement better practices and clinical decisions. Therefore, the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) was revised through expert consensus on pharmacotherapy for bipolar disorder. @*Methods@#We revised the KMAP-BP 2018 questionnaire and conducted a survey of expert clinicians. Out of ninety-three members of the review committee, eighty-seven completed the survey. We analyzed the answers, discussed the data, and held a clinician hearing. Here, we report the results from KMAP-BP 2022. @*Results@#The preferred first-step strategies for acute euphoric mania are a combination of a mood stabilizer (MS) and an atypical antipsychotic (AAP), MS monotherapy, and AAP monotherapy. For psychotic mania, an MS and AAP combination, and AAP monotherapy are preferred. For hypomania, MS monotherapy and AAP monotherapy are preferred. The first-step strategies for mild to moderate bipolar depression are MS monotherapy, lamotrigine (LMT) monotherapy, AAP monotherapy, an MS+AAP combination, and an AAP+LMT combination. For non-psychotic severe depression, the MS+AAP combination, the AAP+LMT combination, and the MS+LMT combination are preferred. For psychotic severe depression, MS+AAP and AAP+LMT are preferred. @*Conclusion@#We obtained expert consensus and developed KMAP-BP 2022. Compared with KMAP-BP 2018, we can figure out clinicians’ preferences and decisions in real clinical situations more clearly. The preference for AAP increased, and that of MS and an antidepressant decreased. We hope KMAP-BP 2022 is helpful for clinicians who treat patients with bipolar disorder.

RESUMEN

Objectives@#The Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) is a consensus-based medication guideline. To reflect advances in pharmacotherapy for bipolar disorders, we updated KMAP-BP to provide more timely information for clinicians. @*Methods@#We conducted a survey using a questionnaire on treatments formanic/hypomanic episodes. Eighty-seven members among ninety-three members of the review committee (93.5%) completed the survey. Each treatment strategy or treatment option for manic/hypomanic episodes was evaluated with an overall score of 9, and the resulting 95% confidence interval treatment options were categorized into three recommendation levels (primary, secondary, and tertiary). The executive committee analyzed the results and discussed the final production of an algorithm by considering the scientific evidence. @*Results@#The combination of a mood stabilizer and an atypical antipsychotic, monotherapy with a mood stabilizer, or monotherapy with an atypical antipsychotic were recommended as the firstline pharmacotherapeutic strategy for the initial treatment of mania without psychotic features. The mood stabilizer and atypical antipsychotic combination was the treatment of choice, and atypical antipsychotic monotherapy was the first-line treatment for mania with psychotic features. When initial treatment fails, a combination of mood stabilizer+atypical antipsychotic and switching to another first-line agent is recommended. For hypomania, monotherapy with either mood stabilizer or atypical antipsychotic is the recommended first-line treatment, but the mood stabilizer+atypical antipsychotic combination is recommended as well. @*Conclusion@#It is notable that there were changes in the preferences for the use of individual atypical antipsychotics, and the preference for the use of mood stabilizer increased for treatment-resistant mania.

RESUMEN

Objectives@#After the Korean Medication Algorithm Project for Bipolar Disorder (KMAP-BP) was developed in 2002, its fifth revision was completed in 2022 to reflect the recent rapid developments and research into bipolar disorder and its psychopharmacology. @*Methods@#According to the methodology for previous versions, the depressive episode section of KMAP-BP 2022 was revised based on a survey consisting of 11 questions. Among ninetythree experts, eighty-seven members of the review committee (93.5%) completed the survey.The executive committee analyzed the results and discussed the final production of an algorithm by considering the scientific evidence. @*Results@#Overall, the results from this study showed little change in comparison with previous versions of KMAP-BP. However, there have been significant changes in recommendations over the span of about 20 years. The preferences for lamotrigine and atypical antipsychotics, especially aripiprazole, quetiapine, and olanzapine, have shown a tendency to continuously increase, but the preferences for risperidone and ziprasidone have not increased, but have decreased. Moreover, the preference for typical antipsychotics has significantly decreased. Additionally, concerns over the use of antidepressants in bipolar depression have been raised, and their use is not recommended in KMAP-BP 2022 as a first-line treatment. @*Conclusion@#Pharmacotherapy for acute depressive episodes with various clinical progressions and various subtypes still shows diversity, compared to pharmacotherapy for mania. We look forward to the development of bipolar depressive, episode-specific therapeutic drugs in the future, and hope the fifth update of KMAP-BP will be a complementary option for clinicians and their patients with bipolar disorder.

RESUMEN

Objectives@#Treatment guidelines or an algorithm can help clinicians implement better practices and clinical decisions. Therefore, the Korean Medication Algorithm Project for Bipolar Disorder 2022 (KMAP-BP 2022) was revised again through a consensus of expert opinion. The diagnosis and treatment of mixed features are not simple, and there are many things to discuss. We describe the preferences and recommendations from KMAP-BP 2022 for the treatment of mood episodes with mixed features. @*Methods@#We revised the KMAP-BP 2018 questionnaire and conducted the survey with expert clinicians. Out of ninety-three members of the review committee, eighty-seven completed the survey. We analyzed the answers, discussed the data, and held a clinician hearing. @*Results@#In first-step strategies for mixed features with more manic symptoms, a combination of a mood stabilizer and an atypical antipsychotic is the treatment of choice. Mood stabilizer monotherapy and atypical antipsychotic monotherapy are preferred strategies. For mixed features with more depressive symptoms, a combination of mood stabilizer and atypical antipsychotic, a combination of atypical antipsychotic and lamotrigine (LMT), atypical antipsychotic monotherapy, a combination of mood stabilizer and LMT, and mood stabilizer monotherapy are preferred. For mixed features with similar manic symptoms and depressive symptoms, a combination of mood stabilizer and atypical antipsychotic, atypical antipsychotic monotherapy, and mood stabilizer monotherapy are preferred. @*Conclusion@#For mixed features, a combination of mood stabilizer and atypical antipsychotic is generally preferred, and LMT is preferred for depressive symptoms. Compared with KMAP-BP 2018, more diverse strategies and drugs are being attempted for the treatment of mixed features.

RESUMEN

Bipolar disorder is a mental illness that causes extreme mood swings and has a chronic course. However, the mechanism by which mood episodes with completely opposite characteristics appear repeatedly, or a mixture of symptoms appears, in patients with bipolar disorder remains unknown. Therefore, mood stabilizers are indicated only for single mood episodes, such as manic episodes and depressive episodes, and no true mood-stabilizing drugs effective for treating both manic and depressive episodes currently exist. Therefore, in this review, therapeutic targets that facilitate the development of mood stabilizers were examined by reviewing the current understanding of the neuromolecular etiology of bipolar disorder.

RESUMEN

The Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) first was published in 2002, and has been revised four times, in 2006, 2012, 2017, and 2021. In this review, we compared recommendations from the recently revised KMAP-DD 2021 to four global clinical practice guidelines (CPGs) for depression published after 2010. The recommendations from the KMAP-DD 2021 were similar to those from other CPGs, although there were some differences. The KMAP-DD 2021 reflected social culture and the healthcare system in Korea and recent evidence about pharmacotherapy for depression, as did other recently published evidence-based guidelines. Despite some intrinsic limitations as an expert consensus-based guideline, the KMAP-DD 2021 can be helpful for Korean psychiatrists making decisions in clinical settings by complementing previously published evidence-based guidelines, especially for some clinical situations lacking evidence from rigorously designed clinical trials.

RESUMEN

Objectives@#This study aimed to identify the vaccination rate for pneumococcus among aged 65 or older, and at the same time to determine the reasons for vaccination or non-vaccination. @*Methods@#The population of this study was aged 65 or older, with a total of 1,150 subjects to be analyzed and a computer assisted telephone interviewing was used. The survey included pneumococcal vaccination status, reasons of vaccination, sources of information on vaccination, reasons for not vaccination, and other related factors. @*Results@#The vaccination rate for pneumococcus among aged 65 or older was 56.2 percent, lower than 69.0 percent in the U.S. (2017), and 69.2 percent in the U.K. (2019). Among the factors related to the pneumococcal vaccination, the groups with the high vaccination rate were women, low age groups, residents of urban areas, people without a job, people with high education, medical insurance subscribers, married people, and people who have family members. In addition, the groups with high vaccination rates were those with high awareness, those who received recommendations from doctors, those who had vaccination records, those who believed in vaccination effects, and those who saw public service advertisements. @*Conclusions@#In the future, it is necessary to develop alternatives to accurately manage vaccination records for adults who are not eligible for state support, and regular adult vaccination rates should be calculated so that they can be used as evidence for the country's infection control policy.

RESUMEN

Background@#This study explores the correlation among obesity, suicide plans, and suicide attempts in adults over 19 years of age in South Korea. @*Methods@#The study used data from adults who had participated in the 2018 Korea National Health and Nutrition Examination Survey. Obesity was defined as having a body mass index of ≥25 kg/m 2 . To identify differences between the characteristics of those who had reported suicide plans and attempts, a complex sample chi-square test was conducted. To analyze the effect of obesity on suicide plans and attempts, a logistic regression analysis was performed. @*Results@#There was no significant difference in the rate of suicide plans in one year between obese and non-obese groups; however, the rate of actual suicide attempts was significantly high in the obese group (p<0.050). After correcting for variables that were significantly different between the groups, obesity was found to have no significant effect on suicide plans but was linked to a significant increase in suicide attempts (odds ratio=3.355, p=0.008). @*Conclusion@#Obesity was found to have no effect on the suicide planning rate; however, the probability of a suicide attempt was high in obese adults.

RESUMEN

Objective@#This study aimed to validate a deep learning-based fully automatic calcium scoring (coronary artery calcium [CAC]_auto) system using previously published cardiac computed tomography (CT) cohort data with the manually segmented coronary calcium scoring (CAC_hand) system as the reference standard. @*Materials and Methods@#We developed the CAC_auto system using 100 co-registered, non-enhanced and contrast-enhanced CT scans. For the validation of the CAC_auto system, three previously published CT cohorts (n = 2985) were chosen to represent different clinical scenarios (i.e., 2647 asymptomatic, 220 symptomatic, 118 valve disease) and four CT models. The performance of the CAC_auto system in detecting coronary calcium was determined. The reliability of the system in measuring the Agatston score as compared with CAC_hand was also evaluated per vessel and per patient using intraclass correlation coefficients (ICCs) and Bland-Altman analysis. The agreement between CAC_auto and CAC_hand based on the cardiovascular risk stratification categories (Agatston score: 0, 1–10, 11–100, 101–400, > 400) was evaluated. @*Results@#In 2985 patients, 6218 coronary calcium lesions were identified using CAC_hand. The per-lesion sensitivity and falsepositive rate of the CAC_auto system in detecting coronary calcium were 93.3% (5800 of 6218) and 0.11 false-positive lesions per patient, respectively. The CAC_auto system, in measuring the Agatston score, yielded ICCs of 0.99 for all the vessels (left main 0.91, left anterior descending 0.99, left circumflex 0.96, right coronary 0.99). The limits of agreement between CAC_auto and CAC_hand were 1.6 ± 52.2. The linearly weighted kappa value for the Agatston score categorization was 0.94. The main causes of false-positive results were image noise (29.1%, 97/333 lesions), aortic wall calcification (25.5%, 85/333 lesions), and pericardial calcification (24.3%, 81/333 lesions). @*Conclusion@#The atlas-based CAC_auto empowered by deep learning provided accurate calcium score measurement as compared with manual method and risk category classification, which could potentially streamline CAC imaging workflows.

RESUMEN

Objectives@#An expert consensus guideline for the treatment of depressive disorder, the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD), was first established in 2002 and updated in 2017. To provide an up-to-date treatment guideline, KMAP-DD 2021 was recently completed. This study was undertaken to provide a guideline for the treatment of depressive disorder in a selected population that included females and elderly. @*Methods@#The survey conducted consisted of 7 questionnaires for each population, females and elderly, with depressive disorder. A total of 65 of 97 experienced psychiatrists answered the survey. @*Results@#For the treatment of premenstrual dysphoric disorder, the selective serotonin reuptake inhibitors, venlafaxine, and desvenlafaxine were recommended as first-line therapies. For major depressive disorder (MDD) during pregnancy, antidepressant (AD) monotherapy was recommended as a first-line therapy for mild to moderate and severe depression, and combined electroconvulsive therapy and AD with atypical antipsychotics (AAP) were recommended as a first-line therapy for severe depression with psychotic features. AD plus AAP was generally recommended for post-partum depression. In elderly with depression, AD monotherapy was recommended as the treatment of choice for mild to moderate episodes, and AD monotherapy and AD plus AAP were recommended as a first-line therapy for severe depression without psychotic features. Lastly, AD plus AAP was chosen as the treatment of choice for psychotic depression. @*Conclusion@#Present study provides an updated algorithm for the treatment of females and elderly with depressive disorders. This algorithm provides a practical aid to clinicians for the treatment of females and elderly with MDD.
