To develop the 'Stronger Towns Index': a deprivation index that took into account characteristics of areas encompassing towns that may be eligible for redevelopment funding and explore how this index was associated with self-rated health and migration within England between 2001 and 2011.. There were areas in the lowest deciles of Town Strength who did not receive funding. After multiple adjustment, LS members living in areas with higher deciles were significantly more likely (7% to 38%) to report good health than those in the lowest decile in 2001. Remaining in the same decile between 2001 and 2011 was associated with 7% lower odds of good self-rated health in 2011.. It is important to consider health in towns when allocating funding.

The map can also be used to help guide research commissioning, by evidence synthesis teams and evidence intermediaries to inform policy during the ongoing pandemic and potential future outbreaks of COVID-19 or other respiratory infections.

Radiolabeled autologous leukocytes are the gold standard for imaging infectious foci in patients. Good results have also been reported for radiolabeled heterologous leukocytes from noninfected donors. Until now, the 2 methods have not been directly compared. In this study, we compared the infection-imaging potential of 99mTc-hexamethylpropyleneamine oxime (HMPAO)-labeled autologous granulocytes with that of 99mTc-HMPAO-labeled granulocytes from either infected or noninfected donors in rabbits with Escherichia coli infection.. The radiolabeled granulocyte preparations were studied in rabbits with an E. coli infection in the left calf muscle. The soft-tissue infections were scintigraphically visualized after injection of 18 MBq of either 99mTc-HMPAO purified autologous granulocytes or radiolabeled purified heterologous granulocytes from infected or noninfected donor rabbits. Gamma camera images were acquired at 2 min and at 1, 2, and 4 h after injection. After the last image, the rabbits were killed and uptake of the radiolabel in the dissected tissues was determined.. The 99mTc-HMPAO autologous granulocytes and heterologous granulocytes from infected donors accurately revealed the infectious focus in the calf muscle at 2 h after injection. At 4 h after injection, a significantly better (P < 0.05) delineation of the infection was established with the 99mTc-HMPAO autologous granulocytes and 99mTc-HMPAO heterologous granulocytes from the infected rabbits than with the heterologous granulocytes from noninfected donors. With both cell preparations, the intensity of uptake in the infected calf muscle continuously increased until 4 h after injection. The 99mTc-HMPAO heterologous granulocytes from noninfected donors showed no significant increase in contrast after 2 h after injection. Absolute uptake in the infected calf muscle was much higher for 99mTc-HMPAO autologous granulocytes (7.81 +/- 1.21 percentage injected dose [%ID]) and 99mTc-HMPAO heterologous infected granulocytes (8.91 +/- 1.92 %ID) than for the radiolabeled heterologous noninfected granulocytes (2.32 +/- 0.75 %ID) (P < 0.04) at 4 h after injection. The ratio of infected muscle to noninfected contralateral muscle was significantly higher for 99mTc-HMPAO autologous granulocytes and 99mTc-HMPAO heterologous granulocytes from infected donors than for 99mTc-HMPAO heterologous granulocytes from noninfected donors (5.53 +/- 1.09, 3.86 +/- 0.75, and 1.86 +/- 0.31, respectively; P < 0.05).. For nuclear medicine imaging of infection, purified granulocytes derived from infected rabbits are superior to purified granulocytes derived from noninfected donor rabbits. In addition, autologous granulocytes gave similar results to heterologous granulocytes from infected donor rabbits, suggesting the need for intrinsic cell activation for specific granulocyte migration.

Posttraumatic osteomyelitis was investigated in 23 patients using nuclear medicine techniques. Tc-99m hexamethylpropilene amine oxime (HMPAO)-labeled leukocyte scintigraphy was performed in 11 patients, and Tc-99m nanocolloid scanning was performed in the other 12 patients. The scintigraphic findings were compared with clinical, laboratory, radiologic, and bacteriologic results. The findings on leukocyte imaging were consistent with the clinical symptoms in 7 of 11 patients, with the laboratory pattern in 7 of 10 patients, with the radiologic findings in 7 of 11 patients, and with the results of bacteriology in 6 of 7 patients. The findings on nanocolloid scintigraphy corresponded with the clinical symptoms in 9 of 12 patients, with the laboratory pattern in 8 of 10 patients, with the radiologic findings in 8 of 12 patients, and with the bacteriology in 4 of 5 patients. The results suggest that both methods were of similar value for the detection of chronic posttraumatic osteomyelitis regardless of whether the process was active. Conversely, on the basis of semiquantitative analysis of the images, leukocyte scintigraphy seemed to characterize the grade of inflammation better than did nanocolloid scintigraphy.

The performance of 99mTc Stealth liposomes was investigated in various rat models.. Preformed polyethyleneglycol-containing liposomes with encapsulated reduced glutathione, were radiolabeled using the lipophilic 99mTc-HMPAO. The labeled liposomes were intravenously administered to rats with focal S. aureus or E. coli infection, or turpentine-induced inflammation. For comparison, Tc-99m-nanocolloid- and 99mTc-labeled nonspecific IgG were tested. In rats with Pneumocystis carinii pneumonia (PCP), Tc-99m-liposomes were directly compared to In-111 labeled nonspecific IgG.. Technetium-99m-liposomes accumulated in the infectious and inflammatory muscle foci over 24 hr (0.59% injected dose per gram tissue (%ID/g) for S. aureus; 1.18 %ID/g for turpentine). Abscess-to-muscle ratios increased to values as high as 24.0, 41.7 and 44.5 for the respective models at 24 hr postinjection. Technetium-99m-liposomes visualized the foci as early as 1 hr postinjection. Technetium-99m-IgG visualized S. aureus infection, but abscess-to-muscle ratios and abscess uptake at the later time points were significantly lower. Technetium-99m-nanocolloid failed to visualize any of the muscle foci. In PCP however, 99mTc-liposomes did not show preferential localization in the infection. The control agent 111In-IgG showed a significant, two-fold increase in lung uptake.. Technetium-99m-Stealth liposomes preferentially accumulated in abscesses, leading to very high target-to-nontarget ratios. This property appears to be related to a process based on uptake of long-circulating particles. In a specific type of infection, i.c. PCP, 99mTc-liposomes did not accumulate in diseased lung tissue, thus mimicking the in vivo behavior of labeled leukocytes.
