RESUMEN

INTRODUCTION:  In the United States (U.S.), African Americans and other minority groups have longer wait times for kidney transplantation than Caucasians. To date, many studies analyzing time spent on the waitlist for each race/ethnicity have been done. However, there are few to no studies examining waitlist time after the 2019 policy changes to the geographic distribution of donated kidneys. METHODS: Data collected from the National Organ Procurement and Transplantation Network database were used to analyze associations between race and time spent on the waitlist for a kidney transplant in the U.S. Additional sub-categorical data were analyzed to determine further associations and potential covariates, such as gender, age, citizenship, primary source of payment, region of transplant center, BMI, Kidney Donor Profile Index (KDPI), renal diagnosis, and presence/type of diabetes. Data were analyzed using odds ratios and validated by Bonferroni-Holm's corrected chi-square tests at confidence intervals of 95% to determine if there are statistically significant differences between transplant time spent on the waitlist and ethnicity, as well as age, diagnosis category, region of transplant center, and KDPI. RESULTS: Statistically significant increased odds of remaining on the transplant list at two years existed for all non-white races/ethnicities, except those identifying as multiracial. Asian American candidates had the greatest odds of remaining on the waitlist greater than two years in comparison to white candidates: 1.51 times that of a patient categorized as white (odds ratio [OR] 1.51, confidence interval [CI] 1.44-1.57). African American/Black, (OR 1.38, CI 1.34-1.43) Pacific Islander (OR 1.38, CI 1.17-1.63), Hispanic candidates (OR 1.37, CI 1.32-1.41), and American Indian or Native Alaskan candidates (OR 1.23, CI 1.12-1.46) also had increased odds of remaining on the transplant waitlist greater than two years compared to white candidates. DISCUSSION: In this study, ethnic disparities persisted as a barrier for non-white individuals receiving treatment for end-stage kidney disease, specifically in the context of time spent on the waitlist for a kidney transplant. Further research is needed regarding the causes of these disparities in time spent on the waitlist, such as cultural restrictions in organ donation, racial differences in parameters for organ match, and institutionalized racism in health care practitioners.

RESUMEN

Background On June 24, 2022, the United States (U.S.) Supreme Court ruled in Dobbs v. Jackson Women's Health that the Constitution does not grant women the right to abortion. This new ruling may have a profound impact on not only the attitudes of medical trainees but the nature in which they are trained when it comes to abortion practices, indications, or procedures. Some clinics where medical schools provide first-hand abortion experience have closed. As a surge of extreme restrictions on abortion has been seen in certain states in the U.S., medical schools and residency programs need to address these issues to ensure future physicians are adequately prepared. The purpose of this study was to assess factors that influence medical students' attitudes toward abortion, specifically knowledge about abortion, religiosity, and philosophical group affiliation regarding abortion (i.e., "pro-choice vs. "pro-life"). Methodology This cross-sectional study collected data from a convenience sample of 413 medical students between October and December 2022 via an online, anonymous questionnaire. Major study variables as depicted in the published literature led to the development of the Abortion Attitudes Questionnaire (AAQ) for medical students. The AAQ contained validated scales to assess the contribution of levels of abortion knowledge and religiosity as well as sample characteristics on attitudes about abortion in medical students. Speakman rank correlation and linear multivariate regression were used for hypothesis testing to explore the contributions of the dependent variables to attitudes about abortion in medical students. Results The mean age of the participants was 25.8 years (SD = 2.96; range = 21-45 years). Linear regression modeling indicated that religiosity, abortion knowledge, being a woman, and group affiliation regarding abortion ("pro-choice" or "pro-life") explained a significant amount of the variance (60%) in abortion attitudes scores in medical students. A significant regression equation was found, F(6,373) = 83.570, p < 0.0001, R2 = 0.603, R2 adjusted = 0.611). Less religiosity, greater abortion knowledge, being a woman, and identifying as "pro-choice" significantly contributed to more positive attitudes toward abortion in this sample of medical students. Interestingly, while moderately correlated with abortion attitudes (r = 0.436,p < 0.01), the single item regarding the importance of religion in one's life did not contribute to the model. Conclusions The present study is the first, to our knowledge, to identify medical student characteristics (i.e., sex, "pro-choice" vs. "pro-life" group affiliation, level of knowledge about abortion, and religiosity) as indicators of abortion attitudes. With the reversal of Roe v. Wade, attention must be given to the possible change in medical students' attitudes toward abortion (as well as any newly developed constraints on clinical training) and to ensure the provision of comprehensive education as U.S. states will determine the limits of these practices and procedures. While further research in this area is needed, findings from this study can help assess students' attitudes about abortion and guide medical education efforts to better prepare tomorrow's obstetrics and gynecology physicians.

RESUMEN

PURPOSE: This study examined the speech acoustic characteristics of Jamaican Creole (JC) and English in bilingual preschoolers and adults using acoustic duration measures. The aims were to determine if, for JC and English, (a) child and adult acoustic duration characteristics differ, (b) differences occur in preschoolers' duration patterns based on the language spoken, and (c) relationships exist between the preschoolers' personal contextual factors (i.e., age, sex, and percentage of language [%language] exposure and use) and acoustic duration. METHOD: Data for this cross-sectional study were collected in Kingston, Jamaica, and New York City, New York, United States, during 2013-2019. Participants included typically developing simultaneous bilingual preschoolers (n = 120, ages 3;4-5;11 [years;months]) and adults (n = 15, ages 19;0-54;4) from the same linguistic community. Audio recordings of single-word productions of JC and English were collected through elicited picture-based tasks and used for acoustic analysis. Durational features (voice onset time [VOT], vowel duration, whole-word duration, and the proportion of vowel to whole-word duration) were measured using Praat, a speech analysis software program. RESULTS: JC-English-speaking children demonstrated developing speech motor control through differences in durational patterns compared with adults, including VOT for voiced plosives. Children's VOT, vowel duration, and whole-word duration were produced similarly across JC and English. The contextual factor %language use was predictive of vowel and whole-word duration in English. CONCLUSIONS: The findings from this study contribute to a foundation of understanding typical bilingual speech characteristics and motor development as well as schema in JC-English speakers. In particular, minimal acoustic duration differences were observed across the post-Creole continuum, a feature that may be attributed to the JC-English bilingual environment.

RESUMEN

There are many different types of gallbladder diseases, mainly resulting from inflammation. The long-term presence of an insult to the gallbladder leads to chronic inflammation, which is a nidus for complications such as Mirizzi syndrome and gallbladder cancer, both of which can become mimics of one another. Preoperative diagnosis of either gallbladder cancer or Mirizzi syndrome is often difficult, leading to late diagnosis and complicating the patient's treatment course. We report a case of a 65-year-old male who presented with abdominal pain and significant weight loss, with no physical evidence of jaundice and normal liver function. This was initially diagnosed as acute cholecystitis and Mirizzi syndrome before being diagnosed as gallbladder adenocarcinoma on final histology.

RESUMEN

PURPOSE: The aim of this study was to characterize speech acoustics in bilingual preschoolers who speak Jamaican Creole (JC) and English. We compared a standard approach with a culturally responsive approach for characterizing speech sound productions. Preschoolers' speech productions were compared to adult models from the same linguistic community as a means for providing confirmatory evidence of typical speech patterns specific to JC-English speakers. METHOD: Two protocols were applied to the data collected using the Diagnostic Evaluation of Articulation and Phonology (DEAP) Articulation subtest: (a) the standardized DEAP protocol and (b) a culturally and linguistically adapted protocol reflective of the Jamaican post-Creole (English to Creole) continuum. The protocols were used to analyze responses from JC-English-speaking preschoolers (n = 119) and adults (n = 15). Responses were analyzed using acoustic (voice onset time, whole-word duration, and vowel duration) and perceptual (percentage of consonant correct-revised and response frequencies) measures. RESULTS: The culturally responsive protocol captured variation in the frequency and acoustic differences produced in the post-Creole continuum, with higher amounts of "other" responses compared to "standard" target responses for both children and adults. Adults' whole-word durations were shorter and showed more consistent prevoicing during initial plosives compared to the children. CONCLUSIONS: Applying culturally responsive methods, including knowledge of the variation produced in the post-Creole continuum and with adult models from the same linguistic community, improved the ecological validity of speech characterizations for JC-English preschoolers. Acoustic properties of speech should be investigated further as a means of describing bilingual development and distinguishing between difference and disorder.

RESUMEN

The present study investigated the sensitivity and specificity of the English Intelligibility in Context Scale (ICS) and the ICS-Jamaican Creole (ICS-JC) translation with bilingual preschool-aged Jamaican children. Participants in this study were 262 English-Jamaican Creole simultaneous bilingual children (aged 3;3 to 6;3, M = 4;11, SD = 7.8). The ICS and ICS-JC were administered to parents in auditory form, rather than written form. Although recent evidence has demonstrated the validity and reliability of the ICS as an assessment tool in various languages, further data are needed to determine diagnostic accuracy of the ICS and ICS-JC in Jamaican children. The sensitivity and specificity of both tools were high in this cohort of children, indicating that in the Jamaican context, these versions of the ICS could be used as screening tools to identify children who require further assessment of speech sound disorders. A cut-off score of 4.12 was used for both tools to achieve high sensitivity (0.84) and specificity (0.70) values for the ICS, as well as high sensitivity (0.84) and specificity (0.71) for the ICS-JC. The results of this study also demonstrate that administration of the auditory ICS is a valid way of collecting parent reports about children's speech intelligibility, which has implications for use of the ICS in languages with no written form or with parents who have a low level of literacy in the languages they use. This investigation is relevant not only to this underserved population but broadens knowledge of research-based tools for working with bilingual children.

RESUMEN

Purpose The purpose of this study is to characterize narrative competence of typically developing bilingual children using Jamaican Creole (JC) and English. Method Story comprehension and fictional storytelling tasks in JC and English were completed by 104 bilingual preschoolers aged 4-6 years. Story comprehension was analyzed using inferential story comprehension questions representing Blank's Question Hierarchy. Fictional storytelling was analyzed using the Monitoring Indicators of Scholarly Language framework for narrative macrostructure and microstructure. Results Story comprehension was significantly correlated within each language, but only questions from Level 4 of Blank's Question Hierarchy showed significant correlations between languages. Fictional storytelling was significantly better in English than in JC for macrostructure (total score, internal response, plan, consequence) and microstructure (total score, adverbs, elaborated noun phrases). Story complexity in JC and English was significantly correlated. In terms of developmental effects, children's macrostructure and story complexity appear to be better at 4 years than 5 years, with English outperforming JC. Furthermore, age correlated with story comprehension in JC. Conclusion Comparison of narrative competence in bilingual children provides much needed insights into language development, with examination of JC and English bilinguals representing an understudied bilingual context.

RESUMEN

Purpose The purpose of this study was to characterize grammatical production in Jamaican Creole (JC) and English using the Index of Productive Syntax (IPSyn; Scarborough, 1990 ) in a sample of typically developing bilingual Jamaicans. Method Spontaneous language samples were collected in JC and English from 62 preschoolers aged 4-6 years. Language samples were analyzed for IPSyn subdomains (Total Score, Noun Phrases, Verb Phrases, Questions/Negations, Sentence Structures), mean length of utterance in morphemes, and number of different words. Child and family demographic information were also collected along with nonverbal IQ performance. Results IPSyn Total Score in JC and English were significantly correlated, and significant correlations were found between IPSyn subdomains in each language for Noun Phrases, Verb Phrases, and Sentence Structures, but not Questions/Negations. Item analysis for the IPSyn items showed that only 7 of the 56 items did not perform similarly in both languages, with performance on only 2 of these being significantly different. IPSyn scores in both languages were correlated with mean length of utterance in morphemes and number of different words, but only IPSyn JC was correlated with nonverbal IQ and age. Conclusion The IPSyn shows promise as a mainstream tool useful in characterizing grammatical productions across languages in typically developing bilingual Jamaican preschoolers.

RESUMEN

Our current conceptualisation of mixed states, defined as co-occurring manic and depressive symptoms, is unlikely to advance our knowledge or inform clinical practice. Episodes of mixed states can no longer be coded in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), and the 'mixed features specifier' fails to capture the most common mixed state presentations. This reflects a lack of understanding of both the importance of mixed states and their underlying pathophysiology. Indeed, research into the nature of mixed states is scarce and uninformative, and most clinical practice guidelines fail to provide advice regarding their management. In this paper, we proffer a reconceptualisation of mixed states that provides a framework for informing clinical practice and research. It is based on the ACE model, which deconstructs mood disorders into three domains of symptoms: activity, cognition, and emotion. Symptoms within each domain vary independently over time and in different directions (towards either excitation or inhibition). By deconstructing mood disorders into component domains, mixed states can be explained as the product of different domains varying 'out of sync'. In most cases, the aetiology of mixed states is unknown. Alongside such idiopathic mixed states, we describe three potential causes of mixed states that are important to consider when formulating management: transitions, ultradian cycling, and treatment-emergent affective switches. In addition to providing guidance on the identification of various kinds of mixed states, we discuss practical strategies for their management, including the monitoring of ACE domains and functioning, to inform the use of psychoeducation and lifestyle changes, psychotherapy, pharmacology, and electroconvulsive therapy.

RESUMEN

INTRODUCTION: In December 2015, the Royal Australian and New Zealand College of Psychiatrists published a comprehensive set of mood disorder clinical practice guidelines for psychiatrists, psychologists and mental health professionals. This guideline summary, directed broadly at primary care physicians, is an abridged version that focuses on major depression. It emphasises the importance of shared decision making, tailoring personalised care to the individual, and delivering care in the context of a therapeutic relationship. In practice, the management of depression is determined by a multitude of factors, including illness severity and putative aetiology, with the principal objectives of regaining premorbid functioning and improving resilience against recurrence of future episodes. Main recommendations: The guidelines emphasise a biopsychosocial lifestyle approach and provide the following specific clinical recommendations: Alongside or before prescribing any form of treatment, consideration should be given to the implementation of strategies to manage stress, ensure appropriate sleep hygiene and enable uptake of healthy lifestyle changes. For mild to moderate depression, psychological management alone is an appropriate first line treatment, especially early in the course of illness. For moderate to severe depression, pharmacological management is usually necessary and is recommended first line, ideally in conjunction with psychosocial interventions. Changes in management as a result of the guidelines: The management of depression is anchored within a therapeutic relationship that attends to biopsychosocial lifestyle aspects and psychiatric diagnosis. The guidelines promote a broader approach to the formulation and management of depression, with treatments tailored to depressive subtypes and administered with clear steps in mind. Lifestyle and psychological therapies are favoured for less severe presentations, and concurrent antidepressant prescription is reserved for more severe and otherwise treatment-refractory cases.

RESUMEN

INTRODUCTION: In December 2015, the Royal Australian and New Zealand College of Psychiatrists published a comprehensive set of mood disorder clinical practice guidelines for psychiatrists, psychologists and mental health professionals. This guideline summary, directed broadly at primary care physicians, is an abridged version that focuses on bipolar disorder. It is intended as an aid to the management of this complex disorder for primary care physicians working in collaboration with psychiatrists to implement successful long term management. Main recommendations: The guidelines address the main phases of bipolar disorder with a particular emphasis on long term management, and provide specific clinical recommendations. Mania: All physicians should be able to detect its early signs so that treatment can be initiated promptly. At the outset, taper and cease medications with mood-elevating properties and institute measures to reduce stimulation, and transfer the patient to specialist care. Bipolar depression: Treatment is complicated and may require trialling treatment combinations. Monotherapy with mood-stabilising agents or second generation antipsychotics has demonstrated efficacy but using combinations of these agents along with antidepressants is sometimes necessary to achieve remission. Commencing adjunctive structured psychosocial treatments in this phase is benign and likely effective. Long term management: Physicians should adjust treatment to prevent the recurrence of manic and/or depressive symptoms and optimise functional recovery. Closely monitor the efficacy of pharmacological and psychological treatments, adverse effects and compliance. Changes in management as a result of the guidelines: The guidelines position bipolar disorder as part of a spectrum of mood disorders and provide a longitudinal perspective for assessment and treatment. They provide new management algorithms for the maintenance phase of treatment that underscore the importance of ongoing monitoring to achieve prophylaxis. As a first line treatment, lithium remains the most effective medication for the prevention of relapse and potential suicide, but requires nuanced management from both general practitioners and specialists. The guidelines provide clarity and simplicity for the long term management of bipolar disorder, incorporating the use of new medications and therapies alongside established treatments.

RESUMEN

OBJECTIVE: A diagnosis of bipolar disorder (BD) is often preceded by an initial diagnosis of depression, creating a delay in the accurate diagnosis and treatment of BD. Although previous research has focused on predictors of a diagnosis change from depression to BD, the research on this delay in diagnosis is sparse. Therefore, the present study examined the time taken to make a BD diagnosis following an initial diagnosis of major depressive disorder in order to further understand the patient characteristics and psychological factors that may explain this delay. METHOD: A total of 382 patients underwent a clinical evaluation by a psychiatrist and completed a series of questionnaires. RESULTS: Ninety patients were initially diagnosed with depression with a later diagnosis of BD, with a mean delay in diagnostic conversion of 8.74 years. These patients who were later diagnosed with BD were, on average, diagnosed with depression at a younger age, experienced more manic symptoms, and had a more open personality style and better coping skills. Cox regressions showed that depressed patients with diagnoses that eventually converted to BD had been diagnosed with depression earlier and that this was related to a longer delay to conversion and greater likelihood of dysfunctional attitudes. CONCLUSION: The findings from the present study suggested that an earlier diagnosis of depression is related to experiencing a longer delay in conversion to BD. The clinical implications of this are briefly discussed, with a view to reducing the seemingly inevitable delay in the diagnosis of BD.

RESUMEN

BACKGROUND: Irritability and emotion regulation are both important transdiagnostic factors that contribute to the development of internalizing symptoms during adolescence. The current study examined whether emotion regulation mediates the relationship between irritability and internalizing symptoms. METHODS: To examine this relationship we analysed the indirect effect of irritability (measured using a single item from the Goldberg Mania Questionnaire) on internalizing symptoms (anxiety and depression) via the mediator, emotion regulation (Difficulties in Emotion Regulation Scale) in 112 adolescent females. RESULTS: Mediation analysis, using bootstrapping, showed a significant indirect effect and suggests that the relationship between irritability and internalizing symptoms is mediated by emotion dysregulation. LIMITATIONS: These include measuring irritability using a single item and employing a cross sectional design. CONCLUSIONS: These novel findings add to our understanding of the processes and mechanisms by which irritability contributes to the development of internalizing symptoms.

RESUMEN

This article focuses on the controversial decision to exclude the overlapping symptoms of distractibility, irritability, and psychomotor agitation (DIP) with the introduction of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) mixed features specifier. In order to understand the placement of mixed states within the current classification system, we first review the evolution of mixed states. Then, using Kraepelin's original classification of mixed states, we compare and contrast his conceptualization with modern day definitions. The DSM-5 workgroup excluded DIP symptoms, arguing that they lack the ability to differentiate between manic and depressive states; however, accumulating evidence suggests that DIP symptoms may be core features of mixed states. We suggest a return to a Kraepelinian approach to classification-with mood, ideation, and activity as key axes-and reintegration of DIP symptoms as features that are expressed across presentations. An inclusive definition of mixed states is urgently needed to resolve confusion in clinical practice and to redirect future research efforts.

RESUMEN

OBJECTIVE: The aim of the present study was to characterize the neurocognitive effects of lithium in bipolar disorder to inform clinical and research approaches for further investigation. METHODS: Key words pertaining to neurocognition in bipolar disorder and lithium treatment were used to search recognized databases to identify relevant literature. The authors also retrieved gray literature (e.g., book chapters) known to them and examined pertinent articles from bibliographies. RESULTS: A limited number of studies have examined the effects of lithium on neurocognition in bipolar disorder and, although in some domains a consistent picture emerges, in many domains the findings are mixed. Lithium administration appears to reshape key components of neurocognition - in particular, psychomotor speed, verbal memory, and verbal fluency. Notably, it has a sophisticated neurocognitive profile, such that while lithium impairs neurocognition across some domains, it seemingly preserves others - possibly those vulnerable to the effects of bipolar disorder. Furthermore, its effects are likely to be direct and indirect (via mood, for example) and cumulative with duration of treatment. Disentangling the components of neurocognition modulated by lithium in the context of a fluctuating and complex illness such as bipolar disorder is a significant challenge but one that therefore demands a stratified and systematic approach, such as that provided by the Lithium Battery. CONCLUSIONS: In order to delineate the effects of lithium therapy on neurocognition in bipolar disorder within both research and clinical practice, a greater understanding and measurement of the relatively stable neurocognitive components is needed to examine those that indeed change with lithium treatment. In order to achieve this, we propose a Lithium Battery-Clinical and a Lithium Battery-Research that can be applied to these respective settings.

RESUMEN

BACKGROUND: Three symptoms of (hypo)mania that clinically represent mood disorders mixed states have been omitted from the DSM-5 mixed features specifier because 'they fail to discriminate between manic and depressive syndromes'. Therefore, the present study examined the role of distractibility, irritability and psychomotor agitation (DIP) in characterising mixed depressive states. METHODS: Fifty in-patients at a specialist mood disorders unit underwent a detailed longitudinal clinical evaluation (3-6 weeks) and were assessed on a range of standardized measures to characterise their illness according to depression subtype, duration of illness and clinical features-including specifically depressive and manic symptoms and the context in which these occur. RESULTS: 49 patients met criteria for major depressive episode, and of these, 34 experienced at least one dip symptom. Patients who endorsed distractibility were more likely to be diagnosed with Bipolar Disorder than Major Depressive Disorder; patients who endorsed irritable mood were more likely to have non-melancholic depression (admixture of depressive and anxiety symptoms), and patients who reported psychomotor agitation experienced a significantly greater number of distinct periods of (hypo)manic symptoms compared with those who did not. LIMITATIONS: The present study used a modest sample size and did not control for medication or comorbid illness. Although this is inevitable when examining real-world patients in a naturalistic setting, future research needs to allow for comorbidity and its impact, specifically anxiety. CONCLUSIONS: The present findings suggest that all 3 symptoms that have been excluded from DSM-5 may be cardinal features of mixed states, as they 'dip' into depressive symptoms to create a mixed state.

RESUMEN

OBJECTIVES: In recent years, a number of neurocognitive models stemming from psychiatry and psychology schools of thought have conceptualized the pathophysiology of mood disorders in terms of dysfunctional neural mechanisms that underpin and drive neurocognitive processes. Though these models have been useful for advancing our theoretical understanding and facilitating important lines of research, translation of these models and their application within the clinical arena have been limited-partly because of lack of integration and synthesis. Cognitive neuroscience provides a novel perspective for understanding and modeling mood disorders. This selective review of influential neurocognitive models develops an integrative approach that can serve as a template for future research and the development of a clinically meaningful framework for investigating, diagnosing, and treating mood disorders. METHODS: A selective literature search was conducted using PubMed and PsychINFO to identify prominent neurobiological and neurocognitive models of mood disorders. RESULTS: Most models identify similar neural networks and brain regions and neuropsychological processes in the neurocognition of mood, however, they differ in terms of specific functions attached to neural processes and how these interact. Furthermore, cognitive biases, reward processing and motivation, rumination, and mood stability, which play significant roles in the manner in which attention, appraisal, and response processes are deployed in mood disorders, are not sufficiently integrated. The inclusion of interactions between these additional components enhances our understanding of the etiology and pathophysiology of mood disorders. CONCLUSIONS: Through integration of key cognitive functions and understanding of how these interface with neural functioning within neurocognitive models of mood disorders, a framework for research can be created for translation to diagnosis and treatment of mood disorders.

RESUMEN

OBJECTIVES: To provide guidance for the management of mood disorders, based on scientific evidence supplemented by expert clinical consensus and formulate recommendations to maximise clinical salience and utility. METHODS: Articles and information sourced from search engines including PubMed and EMBASE, MEDLINE, PsycINFO and Google Scholar were supplemented by literature known to the mood disorders committee (MDC) (e.g., books, book chapters and government reports) and from published depression and bipolar disorder guidelines. Information was reviewed and discussed by members of the MDC and findings were then formulated into consensus-based recommendations and clinical guidance. The guidelines were subjected to rigorous successive consultation and external review involving: expert and clinical advisors, the public, key stakeholders, professional bodies and specialist groups with interest in mood disorders. RESULTS: The Royal Australian and New Zealand College of Psychiatrists clinical practice guidelines for mood disorders (Mood Disorders CPG) provide up-to-date guidance and advice regarding the management of mood disorders that is informed by evidence and clinical experience. The Mood Disorders CPG is intended for clinical use by psychiatrists, psychologists, physicians and others with an interest in mental health care. CONCLUSIONS: The Mood Disorder CPG is the first Clinical Practice Guideline to address both depressive and bipolar disorders. It provides up-to-date recommendations and guidance within an evidence-based framework, supplemented by expert clinical consensus.
