ABSTRACT

OBJECTIVE: To assess the relation of symptomatic knee osteoarthritis (OA), knee pain, and radiographic knee OA to All-cause mortality and to identify mediators in the causal pathway. METHODS: Participants from the Osteoarthritis Initiative were divided into 4 groups: 1) symptomatic knee OA (i.e., both radiographic knee OA [Kellgren/Lawrence grade ≥2] and knee pain); 2) knee pain only; 3) radiographic knee OA only; and 4) neither radiographic knee OA nor knee pain. We examined the relation of knee OA status to All-cause mortality using a multivariable Cox proportional hazards model and assessed the extent to which the association was mediated by disability, physical component summary (PCS) and mental component summary (MCS) scores for quality of life (QoL), and use of oral pain-relief medications (i.e., nonsteroidal antiinflammatory drugs and opioids). RESULTS: Among 4,796 participants, 282 died over the 96-month follow-up period. Compared with those with neither radiographic knee OA nor knee pain, multivariable-adjusted hazard ratios (HRs) of mortality were 2.2 (95% confidence interval [95% CI] 1.6-3.1) for symptomatic knee OA, 0.9 (95% CI 0.6-1.4) for knee pain only, and 2.0 (95% CI 1.4-2.9) for radiographic knee OA only, respectively. Indirect effects (HRs) of symptomatic knee OA on mortality via disability and PCS of QoL were 1.1 (95% CI 1.0-1.4) and 1.2 (95% CI 1.0-1.4), respectively. No apparent mediation effect was observed through either MCS of QoL or oral pain-relief medications use. CONCLUSION: Participants with either symptomatic or radiographic knee OA were at an increased risk of All-cause mortality. Increased risk of mortality from symptomatic knee OA was partially mediated through its effect on disability and PCS of QoL.

ABSTRACT

From April to September 2017, Bangladesh experienced a huge outbreak of acute Chikungunya virus infection in Dhaka. This series describes the clinical and laboratory features of a large number of cases (690; 399 confirmed and 291 probable) suffered during that period. This observational study was carried out at Dhaka Medical College Hospital, Bangladesh. The median age of the patients at presentation was 38 years (IQR 30-50) with a male (57.3%) predominance. Hypertension and diabetes were the most common comorbidities. The mean (±SD) duration of fever was 3.7 (±1.4) days. Other common manifestations were arthralgia (99.2%), maculopapular rash (50.2%), morning stiffness (49.7%), joint swelling (48.5%), and headache (37.6%). Cases were confirmed by anti-chikungunya IgG (173; 43.3%), IgM (165; 42.3%), and reverse transcription polymerase chain reaction (44; 11.0%). Important laboratory findings include high erythrocyte sedimentation rate (156; 22.6%), raised serum glutamic pyruvic transaminase (73; 10.5%), random blood sugar (54; 7.8%), leukopenia (72; 10.4%), thrombocytopenia (41; 5.9%), and others. The oligo-articular (453; 66.1%) variety of joint involvement was significantly more common compared with the poly-articular (237; 34.5%) variety. Commonly involved joints were the wrist (371; 54.1%), small joints of the hand (321; 46.8%), ankle (251; 36.6%), knee (240; 35.0%), and elbow (228; 33.2%). Eleven cases were found to be complicated with neurological involvement and two of them died. Another patient died due to myocarditis. Public health experts, clinicians, and policymakers could use the results of this study to construct the future strategy tackling chikungunya in Bangladesh and other epidemic countries.

ABSTRACT

The high incidence of hip fracture, together with considerable associated morbidity, mortality, and cost of care, makes this injury a major clinical challenge. Of particular importance is the pain associated with hip fracture, which can have potentially severe consequences and may lead to delayed recovery. The prevailing opioid-dependent model of analgesia, however, presents multiple drawbacks and risks that can compromise outcomes in the hip fracture population. The pain management process has essential preoperative, intraoperative, and postoperative components, yet data on the comparative effectiveness of different pain management interventions in patients undergoing surgery for hip fracture are not clear cut. A Cochrane database review that included 83 different pain management studies indicated that there are not enough well-designed studies to show unequivocally which pain management approaches work well after hip fracture surgery. Yet a growing body of data on certain interventions, such as nerve blocks and multimodal analgesia, supports consideration of these options.

ABSTRACT

UNLABELLED: To assess whether joint pain or radiographic osteoarthritis (ROA) of the knee and hand is associated with all-cause and disease-specific mortality in middle-aged women. METHODS: Four subgroups from the prospective community-based Chingford Cohort Study were identified based on presence/absence of pain and ROA at baseline: (Pain-/ROA-; Pain+/ROA-; Pain-/ROA+; Pain+/ROA+). Pain was defined as side-specific pain in the preceding month, while side-specific ROA was defined as Kellgren-Lawrence grade ≥2. All-cause, cardiovascular disease (CVD) and cancer-related mortality over the 23-year follow-up was based on information collected by the Office for National Statistics. Associations between subgroups and all-cause/cause-specific mortality were assessed using Cox regression, adjusting for age, body mass index, typical cardiovascular risk factors, occupation, past physical activity, existing CVD disease, glucose levels and medication use. RESULTS: 821 and 808 women were included for knee and hand analyses, respectively. Compared with the knee Pain-/ROA- group, the Pain+/ROA- group had an increased risk of CVD-specific mortality (HR 2.93 (95% CI 1.47 to 5.85)), while the knee Pain+/ROA+ group had an increased HR of 1.97 (95% CI 1.23 to 3.17) for all-cause and 3.57 (95% CI 1.53 to 8.34) for CVD-specific mortality. We found no association between hand OA and mortality. CONCLUSION: We found a significantly increased risk of all-cause and CVD-specific mortality in women experiencing knee pain with or without ROA but not ROA alone. No relationship was found between hand OA and mortality risk. This suggests that knee pain, more than structural changes of OA is the main driver of excess mortality in patients with OA.

ABSTRACT

BACKGROUND AND PURPOSE: There is an increase in demand for primary and revision total knee joint procedures. We studied implant survival and functional outcome of patients operated with a constrained condylar knee (CCK) or a rotating hinge implant (RH) as a primary or a revision total knee arthoplasty (TKA). PATIENTS AND METHODS: We evaluated clinically and radiographically 65 surgical procedures with a mean follow-up time of 5 (2-9) years (40 CCK and 25 RH). There were 24 primary TKAs-due to instability-and 41 revision TKAs, mostly due to aseptic loosening. Mean age at the index operation was 68 (31-88) years. RESULTS: Overall, there were 12 failures, including 8 reoperations due to deep infection. The overall 5-year survival rate with reoperation as the endpoint was 82% (95% CI: 72-99). Radiolucent lines on either the femoral or the tibial side were seen in 36 cases. When comparing the cases that were operated as a primary TKA or as a revision TKA, function, health-related quality of life, and survival were similar. However, after primary TKA the patients generally had less pain and a higher proportion of patients were very satisfied or satisfied. INTERPRETATION: Although a high rate of severe complications was observed, most patients improved in function after surgery regardless of whether it was a primary or a revision TKA. We found narrow radiolucent lines-mainly on the tibial side-in nearly half of the cases, but none of the implants were loose radiographically. Overall patient satisfaction and health-related quality of life were high, and a minority had problems with persistent pain.

ABSTRACT

CONTEXT: Joint and muscle aches, pain, and stiffness have been reported to be a problem for some women after adjuvant breast cancer treatment; however, the extent and impact of this problem are unknown. OBJECTIVES: The purpose of this study was to determine the prevalence of this problem in comparison with women of a similar age without breast cancer. METHODS: Two hundred forty-seven women attending breast cancer follow-up clinics were invited to complete pain and quality-of-life measures. A comparison group of 274 women of similar age was drawn from women attending breast screening and benign breast clinics. Prevalence and severity of pain were compared between the two groups. RESULTS: The mean age of all women in the study was 59 years (range 30-86 years). The median time since diagnosis of cancer was 28 months (range 2-184 months). Adjuvant treatments included radiotherapy (79%), chemotherapy (45%), and hormone therapy (81%). Sixty-two percent of women with breast cancer reported pain "today" compared with 53% of women without breast cancer (P = 0.023). Significant predictors of pain in both patient groups were cancer, age, and arthritis. For the cancer cases, significant predictors of pain were age, arthritis, taxane chemotherapy, aromatase inhibitors, and tamoxifen. Quality of life (measured by the Short Form-36) was significantly worse for women with breast cancer compared with controls and was significantly worse in the breast cancer cases with pain. CONCLUSION: Treatment with tamoxifen, taxane chemotherapy, and aromatase inhibitors for breast cancer is predictive of joint pain, which may have an impact on women's lives for some years after breast cancer.
