High-dose therapy and autologous bone marrow transplantation in patients with follicular lymphoma during first remission

We report the results of a study in previously untreated advanced stage patients with follicular lymphoma (FL) who underwent uniform induction chemotherapy with cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) followed by myeloablative therapy and anti-B-cell monoclonal antibody purged autologous bone marrow transplantation (ABMT). Eighty-three patients with previously untreated, low-grade FL were enrolled. After CHOP induction, only 36% achieved complete remission (CR) and 77 patients underwent ABMT. Before BM harvest, 70 patients had a known t(14;18), as determined by polymerase chain reaction (PCR), and all remained PCR positive in the BM at harvest. After ABMT, the disease-free survival (DFS) and overall survival are estimated to be 63% and 89% at 3 years, respectively, with a median follow-up of 45 months. Patients whose BM was PCR negative after purging experienced significantly longer freedom from recurrence (FFR) than those whose BM remained PCR positive (P = .0006). Continued PCR negativity in follow-up BM samples was also strongly predictive of continued CR. This study suggests that a subset of patients with advanced FL may experience prolonged clinical and molecular remissions following high-dose ablative therapy, although longer follow-up will be necessary to determine potential impact on overall survival.     

Impact of pharmacy outreach services on blood pressure management in the elderly community of Hong Kong

Aim: To investigate the impact of the Pharmacy Outreach Service (POS) on blood pressure (BP) and disease knowledge among community‐dwelling elderly patients with hypertension, and to evaluate the sustainability of such impact of POS. Methods: A prospective open‐labeled study of elderly adults (aged ≥65 years) with hypertension (BP ≥140/90 mmHg for non‐diabetics and ≥130/80 mmHg for diabetics) was carried out at seven elderly community centers from July 2008 to March 2010. Pharmacists provided BP monitoring, medication review and disease knowledge assessment. The target BP was <140/90 mmHg for non‐diabetics and <130/80 mmHg for diabetics. The primary outcome was BP change, whereas the secondary outcome was the change of disease knowledge of hypertension. All outcomes were compared between baseline and the last visit. For POS 2008/09 participants, BP was compared between values obtained during POS 2008/09 and 2009/10. Results: A total of 97 participants were recruited. Systolic BP reduced significantly from 152.38 ± 18.80 mmHg to 147.04 ± 20.72 mmHg (P = 0.021), and diastolic BP reduced from 73.84 ± 11.36 mmHg to 71.03 ± 10.97 mmHg (P = 0.010). Cumulative reductions in mean systolic BP and diastolic BP throughout the 2‐year study period were 21.39 ± 24.72 mmHg and 9.88 ± 13.48 mmHg, respectively (P < 0.001). A 12% increase in the at‐goal rate was observed in new participants recruited in 2009 (P = 0.039). Disease knowledge of hypertension improved significantly (P < 0.005), particularly in areas that included the definition of hypertension, diet and lifestyle modification. Conclusions: The POS might improve blood pressure control, hypertension and diabetes knowledge in elderly adults with hypertension in Hong Kong. The effect on blood pressure improvement was sustainable. Geriatr Gerontol Int 2013; 13: 175–181.     

Foot and leg problems are important determinants of functional status in community dwelling older people

Purpose.?To determine whether foot and leg problems are independently associated with functional status in a community sample of older people after adjusting for the influence of socio-demographic, physical and medical factors.

Method.?Data were analysed from the Health Status of Older People project, a population-based study involving a random sample of 1000 community-dwelling people aged 65?–?94 years (533 females, 467 males, mean age 73.4 years?±?5.87). A structured interview and brief physical examination were used to investigate the associations between self-reported foot and leg problems and functional status. Functional status was assessed using: (i) timed ‘Up & Go’ test, (ii) self-reported difficulty climbing stairs, (iii) self-reported difficulty walking one kilometer, (iv) self-reported difficulty performing instrumental activities of daily living (IADLs), and (v) self-reported history of one or more falls in the previous 12 months. These associations were then explored after adjusting for socio-demographic, physical and medical factors.

Results.?Thirty-six percent of the sample reported having foot or leg problems. Univariate analyses revealed that people with foot and leg problems were significantly more likely to exhibit poorer functional status in all parameters measured. After adjusting for socio-demographic, physical and medical factors, foot and leg problems remained significantly associated with impaired timed ‘Up & Go’ performance (OR?=?2.15, 95%CI 1.55?–?2.97), difficulty climbing stairs (OR?=?3.33, 95%CI 1.98?–?5.61), difficulty walking one kilometer (OR?=?3.13, 95%CI 2.09?–?4.69), and history of falling (OR?=?1.73, 95%CI 1.26?–?2.37).

Conclusions.?Foot and leg problems are reported by one in three community-dwelling people aged 65 years and older. Independent of the influence of age, gender, common medical conditions and other socio-demographic factors, foot and leg problems have a significant impact on the ability to perform functional tasks integral to independent living.     

Metastatic colon cancer: correlation of oxygen levels with I-131 F(ab')2 uptake

Tumor oxygen levels were measured with an electrode in 13 patients with colon carcinoma metastases. These measurements were correlated with images obtained with radiolabeled monoclonal antibody 1083-17-1A. Only those tumors or tumor regions with a mean PO2 of 16 mm Hg or greater were successfully imaged. Tumors and tumor regions with a mean PO2 of less than 16 mm Hg were not imaged, even when the presence of antigen was confirmed with biopsy. These data suggest that physiologic factors other than antigen expression may affect antibody uptake.
