The Role of Purpose in Life in the Relationship Between Widowhood and Cognitive Decline Among Older Adults in the U.S.

OBJECTIVES: The objective of this study was to examine the role of purpose in life in the relationship between widowhood and cognitive decline. METHODS: This study used a sample of 12,856 respondents (20,408 observations) collected from a national panel survey, the 2006-2014 waves of the Health and Retirement Study (HRS), that sampled older adults aged 50 or older. The study estimated growth-curve models with years since spousal death, purpose in life, and interaction between the two to predict cognition using three measures-total cognition, fluid, and crystallized intelligence scores. We also estimated growth-curve models by sex, race/ethnicity, and education. RESULTS: While years since spousal death negatively correlated with cognition, purpose in life positively correlated with cognition. Furthermore, purpose in life had a moderating effect on the relationship between years since spousal death and cognition. This effect was found by using total cognition (coef. = 0.0515; z = 2.64; p < 0.01) and fluid intelligence scores (coef. = 0.0576; z = 3.23; p < 0.05). The same effects were salient among females (coef. = 0.0556; z = 2.19; p < 0.05), Whites (coef. = 0.0526; z = 2.52; p < 0.05), and older adults with more education (coef. = 0.0635; z = 2.10; p < 0.05). CONCLUSION: Higher purpose in life relates to the negative correlations between widowhood and cognition of older adults. Educational programs improving purpose in life are a possible avenue for reducing the adverse effect of widowhood on cognition and warrant future exploration.

Momentary Associations of Osteoarthritis Pain and Affect: Depression as Moderator.

OBJECTIVES: This research examined main and moderating effects of global depressive symptoms upon in-the-moment associations of pain and affect among individuals with knee osteoarthritis (OA). Effects of depression on short-term change in pain and affect were also examined. METHOD: Older adults with physician-confirmed OA (N = 325) completed a baseline interview tapping global depressive symptoms, followed by an experience sampling protocol that captured momentary pain and affect 4 times daily for 7 days. Multilevel models controlling demographics and health conditions examined main and moderating effects of depression on momentary associations of pain with positive affect (PA) and negative affect (NA). Similar methods addressed short-term change in pain and affect. Auxiliary analyses explored broad associations of depressive symptoms with person-level averages and variability in pain and affect. RESULTS: Global depression predicted current pain, PA, and NA, as well as change in pain and affect over a 3- to 8-h period. Furthermore, both in the moment and over short periods, the association of pain and NA was stronger among persons higher in depressive symptoms. No moderating effect for the PA-pain association was found. Depressive symptoms were also associated with variability in pain and affect, particularly NA. DISCUSSION: Results confirm previous work on the relation of chronic pain with both global depressive symptoms and short-term affect. This research further demonstrates a unique moderating role of depression on the association of momentary pain with NA and suggests that the causal path may be stronger from pain to affect than vice versa.

Classic features of primary systemic amyloidosis (AL amyloidosis) leading to diagnosis of plasma cell myeloma.

The diagnosis of primary systemic amyloidosis, also known as AL (amyloid light-chain) amyloidosis, is often delayed owing to its nonspecific manifestations as well as its rarity. A 64-year-old woman presented with an eight-month history of significant weight loss, anemia, fatigue, and progressive painful cutaneous lesions on her hands, lips, back, perianal, and vulvar area that were originally treated unsuccessfully with antimalarials and systemic corticosteroids. Histopathological examination revealed an amorphous dermis with pale pink material that demonstrated positive birefringence with Congo red staining. Subsequently, the patient underwent a bone marrow biopsy, which uncovered a plasma cell myeloma, the source of her amyloidogenic protein production.

Contrast-induced generalized bullous fixed drug eruption resembling Stevens-Johnson syndrome.

A 59-year-old woman with end-stage renal disease presented for suspected Stevens-Johnson syndrome that was ultimately diagnosed as generalized bullous fixed drug eruption (GBFDE) secondary to the administration of iodinated nonpolar radiocontrast. The patient had three previous episodes of a generalized bullous eruption after a thrombectomy, fistulogram, and an arteriovenous fistula revision, all requiring radiocontrast administration. Biopsies taken after previous eruptions demonstrated full-thickness epidermal necrosis, and she was diagnosed with Stevens-Johnson syndrome thought to be due to allopurinol. However, against medical advice she continued taking allopurinol and remained asymptomatic until the current presentation. Based on the clinical appearance and time frame of the eruptions, the patient was diagnosed with GBFDE due to radiocontrast. GBFDE, a rare variant of a fixed drug eruption, can be misdiagnosed as Stevens-Johnson syndrome due to their overlapping features of drug-induced whole-body blisters and variable degrees of epidermal necrosis.

Rowell syndrome with recurrence from photoexacerbation: A case report.

Rowell syndrome is a controversial entity composed of erythema multiforme-like lesions coexisting with lupus erythematosus. We describe a case of a 61-year-old male with a history of systemic lupus erythematosus who presented with photoexacerbated flaccid bullae and erosive plaques after repetitive sun exposure. Based on his clinical history, biopsy, and laboratory findings, he fulfilled diagnostic criteria for Rowell syndrome as described by Zeitouni et al. With oral prednisone, hydroxychloroquine, mycophenolate mofetil, and local wound care with petrolatum, the patient's number of lesions decreased, as well as his pain and tenderness. He subsequently did not develop any new erosions. This case highlights the diagnostic criteria of this hybrid clinicopathological syndrome and its nature of photosensitivity.

SOX-10 staining in dermal scars.

BACKGROUND: Positive staining for SOX10 and the S100 protein are often used in the evaluation of challenging melanocytic neoplasms including melanoma in patient samples. SOX-10 positivity of non-melanocytes in re-excision specimen could complicate the evaluation of invasive melanoma with an invasive desmoplastic component. Therefore, quantifiable data regarding the positivity of SOX-10 in scars will help dermatopathologists to better identify false positive staining. METHODS: A retrospective analysis was performed on 50 re-excision specimens from 2013 to 2017, with a diagnosis of squamous cell carcinoma (SCC) or squamous cell carcinoma in situ (SCCIS). Blocks of re-excision specimens containing scars were stained for SOX-10; results were evaluated by a board-certified dermatopathologist. The sum of the five highest numbers of high-power field (HPF) counts as a proxy for "SOX-10 stain factor," and cell morphological features were analyzed. MART-1 and CD68 immunohistochemical staining was performed to study possible lineage of these SOX-10 positive cells. RESULTS: All 50 specimens showed varying degrees of SOX-10 positivity for histiocytes. SOX-10 positive histiocytes were present in 86% of re-excision scar tissues, of which 71.3% had spindle-shaped or angulated nuclei, and 61.8% had nuclear sizes larger than typical lymphocytes (7 µm). Within the same area of scars, CD68 staining was floridly positive, where as MART-1 staining was overwhelmingly negative. CONCLUSIONS: This study illustrates a potential diagnostic pitfall of using SOX-10 to evaluate re-excision specimens of melanocytic neoplasms and also suggests a previously undescribed staining pattern in scars of SOX-10 positive cells that are not melanocytes. We postulate that such SOX-10 positive cells may represent a small fraction of histiocytes routinely found in scar tissue.

Circumscribed palmar hypokeratosis.

Circumscribed palmar hypokeratosis (CPH) is a benign dermatologic condition characterized by local thinning of the stratum corneum. Herein, we present a 52-year-old woman who presented with an asymptomatic pink depressed papule on the right palm. This was treated with clobetasol 0.05% topically twice a day with no improvement.
