Risk of depressive disorder among patients with head and neck cancer: A nationwide population-based study

Factors associated with depressive symptoms among cancer patients: a nationwide cross-sectional study

OBJECTIVE

Research on factors contributing to depressive symptoms in cancer patients at a national level, encompassing a comprehensive set of variables was limited. This study aimed to address this gap by identifying the factors associated with depressive symptoms among cancer patients through a nationwide cross-sectional analysis.

METHODS

Various factors, including demographic, socioeconomic, behavioral patterns, general and self-rated health status, chronic conditions, dietary habits, and cancer-related factors, were examined. Data was from the National Health and Nutrition Examination Survey. Univariate and multivariate logistic regression analyses were performed to identify associated factors. The receiver-operating characteristic (ROC) curve was used to evaluate the performance of the logistic model.

RESULTS

The findings showed that five sociodemographic factors, two behavioral styles, self-rated health status, comorbid arthritis, two dietary factors and two cancer-related factors were strongly associated with depressive symptoms. Compared with those aged 20-39 years, cancer individuals aged 40-59 years (OR = 0.48, P < 0.05) and those 60 years or older (OR = 0.18, P < 0.05) had lower odds of depression. Positive factors included being never married (OR = 1.98, P < 0.05), widowed, divorced or separated (OR = 1.75, P < 0.05), unemployment (OR = 1.87, P < 0.05), current smoking (OR = 1.84, P < 0.05), inadequate sleep (OR = 1.96, P < 0.05), comorbid arthritis (OR = 1.79, P < 0.05), and poor self-rated health status (OR = 3.53, P < 0.05). No significant association was identified between the Healthy Eating Index 2015 and the Dietary Inflammatory Index with depression (P > 0.05). Shorter cancer diagnosis duration was associated with reduced odds of depression (P < 0.05). The logistic model had an area under the curve of 0.870 (95% CI: 0.846-0.894, P < 0.05).

CONCLUSIONS

Cancer patients should receive enhanced family and social support while cultivating a healthy lifestyle and diet. Incorporating plenty of fruits, greens, and beans is highly recommended, along with establishing a comprehensive health management framework.

Prevalence and persistence of depressive symptoms during the first year postdiagnosis in a large sample of patients with head and neck cancer

PURPOSE

The experience of persistent depressive symptomatology during the first year postdiagnosis has implications for recovery and adjustment by one year postdiagnosis. The present descriptive study sought to examine the prevalence and persistence of mild to moderate-severe depressive symptomology and associated disease-specific health-related quality of life (HRQOL) in patients with HNC.

MATERIALS & METHODS

This study was a prospective observational study at a single-institution tertiary cancer center. Depressive symptomatology was measured using the Beck Depression Inventory (BDI), captured at diagnosis and 3-, 6-, 9-, and 12-months postdiagnosis. HNC-specific HRQOL was measured using the Head and Neck Cancer Inventory (HNCI). Four subgroups were defined by BDI scores over time: persistent-moderate/severe subgroup, persistent-mild subgroup, transient subgroup, and resilient subgroup.

RESULTS

The distribution of patients (N = 946) was 65 (6.9 %) in the persistent-moderate/severe subgroup, 190 (20.1 %) in the persistent-mild subgroup, 186 (19.7 %) in the transient subgroup, and 505 (53.3 %) in the resilient subgroup. Across all four HNCI domains, patients in the persistent-moderate/severe subgroup failed to reach a score of 70 by 12-months postdiagnosis which is indicative of high functioning on the HNCI (aesthetics: M = 42.32, SD = 28.7; eating: M = 32.08, SD = 25.7; speech: M = 47.67, SD = 25.3; social disruption: M = 52.39, SD = 24.3). Patients in the persistent-mild subgroup failed to reach 70 in three of four domains. Patients in the resilient subgroup reached, on average, >70 on all HNCI domains.

CONCLUSIONS

Depression is a considerable issue during the first year postdiagnosis. Avenues for screening and intervention should be incorporated into HNC patient care per clinical practice guidelines to optimize recovery and HRQOL.

A core outcome set for patient-reported dysphagia for use in head and neck cancer clinical trials: An international multistakeholder Delphi study

BACKGROUND

Measuring dysphagia-related patient-reported outcomes (PROs) in Head and Neck Cancer (HNC) patients is challenging due to dysphagia's multidimensional impact, causing inconsistency in outcome reporting. To address this issue, this study derived a consensus-based core outcome set (COS) for patient-reported dysphagia in HNC clinical trials where swallowing is a primary or secondary endpoint.

METHODS

A sample of HNC clinicians, researchers, patients, and caregivers participated in a 2-Round Delphi technique. A Delphi survey, containing a comprehensive list of dysphagia-related PROs, was developed. In Round 1, participants rated item importance on a 5-point scale. Items rated ≥4 by >70% advanced to Round 2, where a consensus meeting addressed items with varied opinions, and the Delphi survey with remaining items was completed. Items rated ≥4 by >70% formed the final COS.

RESULTS

Forty-five participants from nine countries were recruited. After Round 1, 40 items were excluded and 64 advanced to Round 2. After Round 2, a 7-outcome COS was established, comprising the domains of dysphagia symptoms, health status and quality of life.

CONCLUSION

This study achieved consensus among HNC stakeholders on essential dysphagia PROs for HNC clinical trials. It is advisable to include these 7-core concepts in clinical trials involving people with HNC to facilitate treatment comparisons and data synthesis.

Use of ketamine for depression and suicidality in cancer and terminal patients: Review of current data

Depression and suicidality are significant challenges faced by cancer patients, particularly those in advanced stages of the disease or nearing the end of life. Conventional antidepressant therapies often have limited effectiveness or delayed onset of action, making the exploration of alternative treatments crucial. The use of ketamine as a potential treatment for depression and suicidality in cancer and terminal patients has gained considerable attention in recent years. This review article aims to provide a comprehensive analysis of the current data regarding the efficacy and safety of ketamine in this specific population. This review presents an overview of clinical trials and case studies investigating the use of ketamine in this population. It explores the effectiveness of ketamine as a standalone treatment or in combination with other interventions. Furthermore, the article addresses the limitations and future directions of research in this field. It highlights the need for larger, well-controlled studies with long-term follow-up to establish the efficacy, safety and optimal treatment parameters of ketamine for depression and suicidality in palliative care.

Trajectory of Depression among Prostate Cancer Patients: A Secondary Analysis of a Randomized Controlled Trial

Background: While psychological difficulties, such as depression, among prostate cancer patients are known, their longitudinal burden remains understudied. We assessed the burden of depression across low-, intermediate- and high-risk prostate cancer groups, and the association between regret and long-term depression. Methods: Secondary analysis of data from a multi-centered randomized controlled study among localized prostate cancer patients was carried out. Assessments were performed at baseline, and at 3-, 6-, 12- and 24-month follow-up. Depression was assessed using the Center for Epidemiologic Studies Depression (CES-D) scale. A CES-D score ≥ 16 indicates high depression. Regret was measured using the regret scale of the Memorial Anxiety Scale for Prostate Cancer (MAX-PC). The proportion of patients with high depression was compared over time, for each risk category. Logistic regression was used to assess the association between regret, and long-term depression after adjusting for age, race, insurance, smoking status, marital status, income, education, employment, treatment, number of people in the household and study site. Results: The study had 743 localized prostate cancer patients. Median depression scores at 6, 12 and 24 months were significantly larger than the baseline median score, overall and for the three prostate cancer risk groups. The proportion of participants with high depression increased over time for all risk groups. Higher regret at 24-month follow-up was significantly associated with high depression at 24-month follow-up, after adjusting for covariates. Conclusions: A substantial proportion of localized prostate cancer patients continued to experience long-term depression. Patient-centered survivorship care strategies can help reduce depression and regret, and improve outcomes in prostate cancer care.

Economic Burden of Cervical and Head and Neck Cancer in Taiwan from a Societal Perspective

BACKGROUND

Head and neck cancers (HNC) are increasingly recognized as important human papillomavirus (HPV)-related malignancies in addition to cervical cancer (CC). However, data on the socioeconomic impact of HNC and CC in Taiwan are limited.

METHODS

A retrospective cohort study was conducted to estimate the total direct medical cost and indirect productivity loss from CC and HNC between 2014 and 2015. Patient data from the Taiwan National Cancer Registry were analyzed, with matched non-cancer controls from the Taiwan National Healthcare Reimbursement Database. Indirect costs due to premature deaths were calculated using public data from Taiwanese government reports.

RESULTS

In the direct cost analysis, 2083 patients with newly diagnosed CC and 11,078 with newly diagnosed HNC (10,036 males) were identified between 2014 and 2015 and followed up through the end of 2016 or until death. The total direct medical costs incurred in 2014 and 2015 due to HNC were 11.54 times higher in males than in females, and 4.55 times higher than CC. Indirect cost analysis showed the total annual productivity loss was New Taiwan Dollar (NTD) $12 billion in 2019, and 79.99% was attributed to male HNC.

CONCLUSION

In Taiwan, the socioeconomic burden associated with male HNC is high and greater than that seen with CC. While not all HNCs are attributable to HPV infection, prevention of HNC through HPV vaccination should be considered for both sexes.

THE MULTIDISCIPLINARY TEAM (MDT) IN THE TREATMENT OF HEAD AND NECK CANCER - A SINGLE-INSTITUTION EXPERIENCE

Head and neck cancers are associated with significant morbidity and mortality despite advancements in treatment in recent decades. A multidisciplinary approach to the treatment of these diseases is thus of essential importance and is becoming the gold standard. Head and neck tumors also endanger relevant structures of the upper aerodigestive tracts, including bodily functions such as voice, speech, swallowing, and breathing. Damage to these functions can significantly influence quality of life. Thus, our study examined not only the roles of head and neck surgeons, oncologists and radiotherapists, but also the importance of the participation of different scientific professions such as anesthesiologists, psychologists, nutritionists, stomatologists, and speech therapists in the work of a multidisciplinary team (MDT). Their participation results in a significant improvement of patient quality of life. We also present our experiences in the organization and work of the MDT as part of the Center for Head and Neck Tumors of the Zagreb Clinical Hospital Center.

The impact of patient preference in the treatment algorithm for recurrent/metastatic head and neck squamous cell carcinoma

The advent of immune checkpoint inhibitors for recurrent/metastatic head and neck squamous cell carcinoma (RM-HNSCC) has revolutionized the standard of care approach in first-line treatment. The heterogeneity of disease presentation and treatment-related toxicities can be associated with suboptimal patient compliance to oncologic care. Hence, prioritizing quality of life and well-being are crucial aspects to be considered in tailoring the best treatment choice. The aim of our work is to present a short report on the topic of the patient’s preference in regard to treatment and its consequences on quality of life in the recurrent/metastatic setting. According to the literature, there’s an unmet need on how to assess patient attitude in respect to the choice of treatment. In view of the availability of different therapeutic strategies in first-line management of RM-HNSCC, increasing emphasis should be put on integrating patient preferences into the medical decision-making.

Biological, Psychological, and Social Determinants of Depression: A Review of Recent Literature

Depression is one of the leading causes of disability, and, if left unmanaged, it can increase the risk for suicide. The evidence base on the determinants of depression is fragmented, which makes the interpretation of the results across studies difficult. The objective of this study is to conduct a thorough synthesis of the literature assessing the biological, psychological, and social determinants of depression in order to piece together the puzzle of the key factors that are related to this condition. Titles and abstracts published between 2017 and 2020 were identified in PubMed, as well as Medline, Scopus, and PsycInfo. Key words relating to biological, social, and psychological determinants as well as depression were applied to the databases, and the screening and data charting of the documents took place. We included 470 documents in this literature review. The findings showed that there are a plethora of risk and protective factors (relating to biological, psychological, and social determinants) that are related to depression; these determinants are interlinked and influence depression outcomes through a web of causation. In this paper, we describe and present the vast, fragmented, and complex literature related to this topic. This review may be used to guide practice, public health efforts, policy, and research related to mental health and, specifically, depression.

Stigma, depression, and anxiety among patients with head and neck cancer

PURPOSE

Patients with head and neck cancer (HNC) are vulnerable to psychiatric comorbidities, particularly anxiety and depression, and also suffer from cancer stigma. This study aimed to comprehensively compare HNC patients' stigma, depression, and anxiety, and elucidate the underlying relationships among them.

METHODS

This cross-sectional study recruited inpatients with HNC from a medical center. Measurements included a psychiatric diagnostic interview, the Shame and Stigma Scale (SSS), the Hamilton Anxiety Rating Scale (HAM-A), the Hamilton Depression Rating Scale (HAM-D), the Explanatory Model Interview Catalogue (EMIC), and stressors of HNC patients. Structural equation modeling was used to establish models of potential mechanisms.

RESULTS

Those patients having stressors of worry about health (t = 5.21, p < 0.001), worry about job (t = 2.73, p = 0.007), worry about family (t = 2.25, p = 0.026), or worry about economic problems (t = 2.09, p = 0.038) showed significantly higher SSS score than those having no such stressor. The SSS total score was significantly correlated with HAM-A (r = 0.509, p < 0.001), HAM-D (r = 0.521, p < 0.001), and EMIC (r = 0.532, p < 0.001) scores. Structural equation modeling was used to propose the possible effect of stigma on anxiety (β = 0.51, p < 0.001), and then the possible effect of anxiety on depression (β = 0.90, p < 0.001).

CONCLUSION

Stigma is significantly correlated with anxiety and depression and might in HNC patients. Proper identification of comorbidities and a reduction of stigma should be advised in mental health efforts among patients with HNC.

Head and neck cancer patients declining curative treatment: a case series and literature review

There is a scarcity of data assessing outcomes of head and neck cancer patients who refuse treatment for potentially curable disease. We report the data of patients who refused curative treatment at a tertiary referral centre and perform a review of the literature. Patients with a potentially curable mucosal head and neck cancers that were discussed at the multidisciplinary tumour board of a referral centre in a two-year period were included. Two cohorts were obtained: patients who accepted the proposed treatment and those who declined it. Statistical analysis was performed using a univariate analysis with parametric and non-parametric tests. Of a total of 803 patients, 14 (1.74%) refused treatment despite being potentially curable. Their median survival was 6.92 months (range 3-12). Patients who refused treatment were older (73.07 years [95% CI, 66.86-79.28] vs 65.56 years [95% CI, 64.70-66.43], p = 0.030) and more likely to have T4 disease (50% vs 26.04%, p = 0.044). Most patients with curable disease accept conventional treatment and those who refuse it experience dismal outcomes. This report provides objective evidence and can be employed to better counsel patients who refuse curative treatment.

Functional outcomes and tracheostomy dependence following salvage oropharyngeal surgery

Purpose:

Salvage surgical treatment of oropharyngeal cancer is associated with significant morbidity. We aim to identify predictive factors of functional outcomes to improve patient selection and counseling when contemplating salvage oropharyngectomy.

Methods:

Patients with a history of radiation requiring salvage oropharyngeal surgery were identified. Primary outcomes were determined at one year post-salvage surgery and included Gastric tube (G-tube) dependence, dietary restrictions, tracheostomy dependence, and speech intelligibility. Multivariate analyses were performed to identify predictors of the primary outcomes.

Results:

At one year, 45% (22/49) of patients had a G-tube, 68% (33/48) had dietary restrictions, 10% (5/49) remained tracheostomy dependent, and 15% (4/26) had difficulty with speech intelligibility. On univariate analysis, pre-operative G-tube (83% vs. 40%, p=0.04), reconstruction with a free flap (54% vs. 0%, p=0.005), and bony resection (69% vs. 36%, p=0.04) were significantly associated with G-tube dependence at one year. On multivariate analysis, concurrent bony resection remained a significant predictor of G-tube dependence (HR 5.4, 95% CI 1.2–24, p=0.03). Predictors of dietary restriction included free-flap reconstruction (78% vs. 25%, HR 0.13, 95% CI 0.02–0.87, p=0.04) and recurrence after two years (85% vs. 48%, HR 4.9, 95% CI 1.2–21, p=0.03). Supraglottic laryngectomy was significantly associated with tracheostomy dependence on univariate (67% vs. 7%, p=0.001) and multivariate analysis (HR 44.4, 95% CI 2.0–986, p=0.02).

Conclusion and Relevance:

Functional outcomes are suboptimal after salvage oropharyngectomy. Specific patient and disease factors are independently associated with worse speech and swallowing outcomes and may aid in pre-operative patient selection, risk stratification, and shared decision-making.

Depression, anxiety, fatigue, and quality of life in a large sample of patients suffering from head and neck cancer in comparison with the general population

BACKGROUND

Treatment of head and neck cancer (HNC) often leads to visible and severe functional impairments. In addition, patients often suffer from a variety of psychosocial problems, significantly associated with a decreased quality of life. We aimed to compare depression, anxiety, fatigue and quality of life (QoL) between HNC patients and a large sample of the general population in Germany and to examine the impact of sociodemographic, behavioral and clinical factors on these symptoms.

METHODS

We assessed data of HNC patients during the aftercare consultation at the Leipzig University Medical Center with a patient reported outcome (PRO) tool named "OncoFunction". Depression, anxiety, fatigue and QoL were assessed using validated outcome measures including the PHQ-9, the GAD-2, and the EORTC QLQ-C30 questionnaire.

RESULTS

A total of 817 HNC patients were included in our study and compared to a sample of 5018 individuals of the general German population. HNC patients showed significantly higher levels of impairment in all dimensions assessed. Examination of association between depression, anxiety, fatigue and QoL and clinical as well as sociodemographic variables showed significant relationships between occupational status, ECOG-state, body mass index and time since diagnosis.

CONCLUSIONS

HNC patients suffer significantly from psychological distress. The used questionnaires are suitable for the use in daily routine practice and can be helpful to increase the detection of depression, anxiety and fatigue and therefore can improve HNC aftercare.

Depression profile in malignancy patients attending otorhinolaryngology clinic

PURPOSE

Patients with malignancy quite often suffer from physical as well as psychological symptoms due to the shattering diagnosis, and prolonged, incapacitating management. The frequency of the depressive disorder in malignancy is around 8-40%. The present study aims at analysing the socio-demographic profile and magnitude of depressive disorders in patients with malignancy.

METHODS

A cross-sectional study was conducted in malignancy patients attending an Ear Nose Throat department using the PHQ-9 questionnaire.

RESULTS

Total PHQ-9 score ranged from 0 to 19; the mean score was 8.46. Major depressive disorder was seen in 4 (8%) cases, while other depressive disorder occurred in 22 (44%) cases. Mild severity of symptoms was noted in 15 (30%) of the patients. High statistical significance was noted between PHQ-9 score for MDD and other depressive disorder (p value < 0.001).

CONCLUSION

The profile of depressive disorders in malignancy varies; PHQ-9 can be used as a good tool for early detection.

Risk of major depressive disorder in Japanese cancer patients: A matched cohort study using employer-based health insurance claims data

Objective

Patients with cancer are at high risk of depression. However, the risk of major depressive disorder (MDD) after cancer diagnosis has not been studied in a population setting in Japan. This cohort study used a Japanese medical claims database to examine time to MDD in cancer patients and the risk of MDD (hazard ratio; HR) compared with matched cancer‐free controls.

Methods

Primary endpoint was time to MDD (starting 6 months before cancer diagnosis) in adult (18–74 years) cancer patients; secondary endpoint was time to MDD (6 months before to 12 months after cancer diagnosis) in a matched cohort of cancer patients and cancer‐free controls. Multivariate analyses were performed to determine HRs for all cancers and for each cancer site.

Results

Of 35 008 cancer patients (mean age, 53.3 years), 2201 (6.3%) were diagnosed with MDD within 66 months. Matched cancer patients (n = 30 372) had an elevated risk of MDD compared with cancer‐free controls (n = 303 720; HR [95% confidence interval] 2.96 [2.77–3.16]). MDD risk was highest in patients with multiple cancers, pancreatic cancer, and brain cancer. Compared with middle‐aged patients, risk was higher in patients <40 years old and lower in patients ≥65 years old; risk tended to be higher in women than in men.

Conclusions

Compared with cancer‐free individuals, Japanese patients with cancer, mostly <65 years old, had an almost threefold higher risk of developing MDD within 12 months of cancer diagnosis. Physicians should watch for MDD in cancer patients and treat when necessary.

Psychological distress and nutritional status in head and neck cancer patients: a pilot study

Purpose

To determine whether the psychological state of patients with head and neck cancer (HCN) is associated with their nutritional status.

Methods

In 40 patients with locally advanced HNC treated with definitive or adjuvant (chemo)radiotherapy, psychological and nutritional status were assessed before treatment, at its completion and 3 months’ post-therapy. Psychosocial distress was measured using the Hospital Anxiety and Depression Scale questionnaire (HADS-A, HADS-D), whereas the nutritional status was evaluated using standard methods (Nutritional Risk Screening Tool 2002, anthropometric data, dynamometry and laboratory tests) and with a bioelectrical impedance analysis parameter phase angle (PA).

Results

Before treatment, more patients were screened positive for anxiety than at treatment completion (p = 0.037) or 3 months’ post-therapy (p = 0.083). Depression prevalence was non-significantly higher at the end and after therapy. Compared to the baseline, more cachectic patients and a reduction of PA values were found at successive assessments. Anxiety was more often recorded among malnourished/cachectic patients (assessment 1, p = 0.017; assessment 2, p = 0.020) who were also found more frequently depressed (assessment 2, p = 0.045; assessment 3, p = 0.023). Significantly higher PA values were measured in patients without distress determined at 3 months’ post-therapy by the HADS-A (p = 0.027).

Conclusion

The association between the psychological and nutritional status found in this pilot study and the options for intervention warrants further clarification in a larger prospective trial.

Accelerated aging in breast cancer survivors and its association with mortality and cancer recurrence

PURPOSE

To prospectively investigate accelerated aging and its association with total mortality and breast cancer-specific mortality/recurrence among breast cancer survivors.

METHODS

This study included 4218 female breast cancer patients enrolled into a population-based cohort study approximately 6-month post-diagnosis. Information on aging-related symptoms (i.e., self-rated overall health condition, energy level, depression, sleep difficulty, and quality) was collected at 18- and 36-month post-diagnosis surveys. Information on overall health, daily function impairments, survival status, and recurrence was collected at 10-year post-diagnosis survey. Record linkages with vital statistics were conducted to collect mortality information. Cox proportional hazards model was applied.

RESULTS

Among 3041 10-year survivors with a mean age of 63.7 ± 9.7 years, respectively, 52.3%, 19.0%, and 27.6% reported poor health, limitation in daily activity, and climbing floors. Age-specific prevalence revealed that breast cancer survivors reached similar prevalence of the functional limitations 5-10 years earlier than cancer-free women. At the 18-month post-diagnosis survey, respectively, 47.0%, 72.5%, and 25.1% of survivors reported unsatisfied overall health condition, reduced energy level, and depression symptoms. After a median follow-up of 10.9 years, low self-rated overall health, low energy level, and depression were significantly associated with increased total mortality, with hazard ratios (HRs; 95% confidence intervals [CI]) of 3.14 (2.43, 4.06), 1.49 (1.20, 1.84), and 1.59 (1.21, 2.09), respectively. Low self-rated health was associated with breast cancer-specific mortality/recurrence (HR  1.85, 95% CI 1.30, 2.65). No significant association was found for sleep difficulty and quality.

CONCLUSION

Aging-related physical changes/symptoms are commonly presented at 18 months after breast cancer diagnosis and are associated with worse prognosis.

IMPACT

Our findings highlight the concern of accelerated aging among breast cancer survivors.

Prevalence of depression and anxiety among otolaryngology outpatients at Jordan University Hospital

PURPOSE

To determine the prevalence of depression and anxiety among otolaryngology outpatients at Jordan University Hospital.

METHODS

A cross-sectional observational study was conducted between January 2017 and February 2018. The sample included 1328 otolaryngology adult outpatients, who completed (PHQ-9) and (GAD-7) questionnaires for depression and anxiety. Sociodemographic and clinical data were recorded.

RESULTS

Depression and anxiety prevalence rates were 36.1% and 22.9%. The significant risk factors found for them were: age range 30 to 50 years, female sex, divorced status, smoking, alcohol drinking, asthma, family history of psychiatric illness, chronic illnesses, negative life events, secondary education, unemployment, low income, globus pharyngeus, tinnitus, and dizziness.

PRACTICE IMPLICATIONS

Healthcare providers should have the vigilance to suspect and treat these disorders to improve patients' symptoms and quality of life.

Factors associated with depression over time in head and neck cancer patients: A systematic review

Objective

To systematically review the literature on factors associated with a clinical diagnosis of depression or symptoms of depression (depression) among head and neck cancer (HNC) patients.

Methods

The search was conducted in PubMed, PsycINFO, and CINAHL. Studies were included if they investigated factors associated with depression among HNC patients, they were of prospective or longitudinal nature, and English full text was available. The search, data extraction, and quality assessment were performed by two authors. Based on the data extraction and quality assessment, the level of evidence was determined.

Results

In total, 35 studies were included: 21 on factors associated with depression at a single (later) time point, 10 on the course of depression, and four on both. In total, 77 sociodemographic, lifestyle, clinical, patient‐reported outcome measures, and inflammatory factors were extracted. Regarding depression at a single time point, there was strong evidence that depression at an earlier time point was significantly associated. For all other factors, evidence was inconclusive, although evidence suggests that age, marital status, education, ethnicity, hospital/region, sleep, smoking, alcohol, surgery, treatment, tumor location, and recurrence are not important associated factors. Regarding the course of depression, we found inconclusive evidence for all factors, although evidence suggests that gender, age, chemotherapy, pain, disease stage, treatment, and tumor location are not important associated factors.

Conclusion

Depression at an earlier time point is significantly associated with depression later on. Several sociodemographic and clinical factors seem not to be important factors associated with depression. For other factors, further research is warranted.

Association of Depression and Cervical Spondylosis: A Nationwide Retrospective Propensity Score-Matched Cohort Study

Objective: Depression is a psychiatric disorder associated with poorer health outcomes. Inappropriate mechanical stress and aging are factors associated with developing cervical spondylosis. The connection between cervical spondylosis and depression is not developed. Methods: From the health insurance claims data of Taiwan, we identified 34,166 persons newly diagnosed with depression in 2000⁻2010 and 34,166 persons without the disorder frequency matched by sex, age and diagnosis year. Both cohorts were followed up to the end of 2013 to estimate incident cervical spondylosis. We further examined the risk of cervical spondylosis in depressed people taking antidepressants. Results: The incidence of cervical spondylosis was 1.8-fold greater in the depression cohort than in comparison cohort (9.46 vs. 5.36 per 1000 person-years), with an adjusted hazard ratio (aHR) of 1.79 (95% confidence interval (CI) = 1.66⁻1.92). The incidence of cervical spondylosis increased in patients who had taken medications of serotonin-specific reuptake inhibitors (SSRIs) or of non-SSRIs than in those without these medicines (9.13 or 11.5 vs. 6.54 per 1000 person-years, respectively). Conclusions: Patients with depression are at an increased risk of developing cervical spondylosis. Additional efforts in reducing the risk of cervical spondylosis might be required in depressed individuals undergoing anti-depressive therapy.

A comparison of psychological well-being and quality of life between spouse and non-spouse caregivers in patients with head and neck cancer: a 6-month follow-up study

OBJECTIVE

The caregivers of patients with head and neck cancer (HNC) may suffer from impaired psychological well-being and a decreased quality of life (QOL) related to the chronic burden of caring for patients' physical conditions and their mood changes. In this study, we aimed to compare the psychological well-being and QOL between spouse caregivers and non-spouse caregivers of patients with HNC over a 6-month follow-up period.

PATIENTS AND METHODS

This study was conducted using a prospective design with consecutive sampling. We recruited study subjects from the outpatient combined treatment clinic of HNC at a medical center in Southern Taiwan. The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, fourth edition was carried out by a trained senior psychiatrist to diagnose caregivers. Furthermore, one research assistant collected the caregivers' demographic characteristics, clinical data, and clinical rating scales, including the Short Form 36 (SF-36) Health Survey, Hospital Anxiety and Depression Scale (HADS), and Family Appearance, Pulse, Grimace, Activity, and Respiration index at the patients' pretreatment, as well as their 3- and 6-month follow-up appointments.

RESULTS

Of the 143 subjects that successfully completed the study, two-thirds of caregivers were spouses. During the 6-month follow-up period, spouse caregivers demonstrated significantly higher rates of depression diagnosis (p=0.032), higher scores in the depression subscale of HADS (HADS-D) (p=0.010), and lower SF-36 mental component summary (MCS) scores (p=0.007) than non-spouse caregivers. Furthermore, during those 6 months, HADS-D (p=0.007) and the anxiety subscale of HADS scores (p<0.001) significantly decreased, while SF-36 MCS scores significantly increased (p=0.015).

CONCLUSION

The mental health of spouse caregivers of HNC patients was more severely affected than that of non-spouse caregivers during the observed 6-month follow-up period. Therefore, clinicians need to pay more attention to caregivers' psychological distress during patient care, especially for spouse caregivers.
