OBJECTIVES:
Early onset fetal growth restriction substantially contributes to neonatal mor-bidities and mortalities. The main dilemma lies on the timing of delivery, especially for pre- and
peri-viable fetuses, due to the challenge in creating an ideal balance of minimized in-utero hy-
poxia-induced fetal injury or death versus the risks of iatrogenic preterm delivery. We wished to
determine the ideal timing of delivery among growth-restricted fetuses <32 weeks gestation us-
ing a stage-based doppler protocol.
MATERIALS AND METHODS:
A retrospective-cohort study of 67 singleton-pregnant wom-
en with growth restriction at <32 weeks gestation and hospitalized from January 2010 to Sep-
tember 2021 was conducted. Medical records were reviewed, and the outcomes were extracted.
The primary outcomes were arterial pH at birth and mortality, while secondary outcomes includ-
ed neonatal morbidities.
RESULTS:
Fetal growth restriction progressed by an average of 3 stages (41.79%) within a 2-
to 3.5-week period. More than half had arterial pH <7.20, which was lowest at Stage II FGR
(50.00%). The prevalence of neonatal
mortality was 16.42% and was lowest at Stage I (8.70%) and Stage II FGR (18.75%).
CONCLUSION
Doppler studies may be conducted weekly for Stage I, biweekly for Stage II,
every 1-2 days for Stage III and every 12 hours for Stage IV. Delivery is ideal at Stage II as this
resulted in the least number of acidosis and neonatal mortalities.

Problem:Size estimates of key populations at higher risk of HIV exposure are recognized as critical for understanding the trajectory of the HIV epidemic and planning and monitoring an effective response, especially for countries with concentrated and low epidemics such as those in Asia.
Context:To help countries estimate population sizes of key populations, global guidelines were updated in 2011 to reflect new technical developments and recent field experiences in applying these methods.
Action:In September 2013, a meeting of programme managers and experts experienced with population size estimates (PSE) for key populations was held for 13 Asian countries. This article summarizes the key results presented, shares practical lessons learnt and reviews the methodological approaches from implementing PSE in 13 countries.
Lessons learnt:It is important to build capacity to collect, analyse and use PSE data; establish a technical review group; and implement a transparent, well documented process. Countries should adapt global PSE guidelines and maintain operational definitions that are more relevant and useable for country programmes. Development of methods for non-venue-based key populations requires more investment and collaborative efforts between countries and among partners.

INTRODUCTIONWe evaluated reduced back pain in a multiethnic population treated with teriparatide and/or antiresorptives in real-life clinical settings over 12 months.
METHODSThis prospective observational study comprised 562 men and postmenopausal women (mean age 68.8 years) receiving either teriparatide (n = 230), antiresorptives (raloxifene or bisphosphonates; n = 322), or both (n = 10) for severe osteoporosis. The primary endpoint was the relative risk of new/worsening back pain at six months.
RESULTSAt baseline, a higher proportion of teriparatide-treated than antiresorptive-treated patients had severe back pain (30.9% vs. 17.7%), extreme pain/discomfort (25.3% vs. 16.8%), extreme anxiety/depression (16.6% vs. 7.8%) and were confined to bed (10.0% vs. 5.3%). Teriparatide-treated patients had higher visual analog scale (VAS) scores for pain (5.8 ± 2.42 vs. 5.1 ± 2.58) and lower mean European Quality of Life-5 Dimensions (EQ-5D) scores (37.7 ± 29.15 vs. 45.5 ± 31.42) than antiresorptive-treated patients. The incidence of new/worsening back pain at six months for patients on teriparatide and antiresorptives was 9.8% and 10.3% (relative risk 0.99, 95% confidence interval 0.80-1.23), respectively. The incidence of severe back pain at 12 months was 1.3% and 1.6% in the teriparatide and antiresorptive treatment groups, respectively. Teriparatide-treated patients had lower mean VAS (2.71 ± 2.21 vs. 3.30 ± 2.37) and EQ‑5D (46.1 ± 33.18 vs. 55.4 ± 32.65) scores at 12 months. More teriparatide-treated patients felt better (82.7% vs. 71.0%) and were very satisfied with treatment (49.4% vs. 36.8%) compared to antiresorptive-treated patients.
CONCLUSIONPatients treated with either teriparatide or antiresorptives had similar risk of new/worsening back pain at six months.

Illegally paid blood donation was a risk factor for HIV acquisition exclusively in Henan and Hubei Provinces of China, and not in Shanghai. Nucleotide sequences in the gag and env genes of HIV-1 were compared between isolates from Henan and Shanghai regions of China to test whether an expected higher degree of a common source of infections from this unique blood donation transmission risk would be evident as decreased variation among Henan isolates in an exploratory cross-sectional analysis. Among 38 isolates studied, 23 of 23 (100%) from Henan and 8 of 15 (54%) from Shanghai were subtype B. In addition, fewer sequence differences were found in gp41 of subtype B isolates from Henan than from Shanghai isolates. Further studies with additional controls are therefore warranted to confirm the role of the degree of a common source of infections in differences in HIV variation across populations.

Dermal fibroblasts play essential roles in wound healing. However, they lose their normal regenerative functions under certain pathologic conditions such as in chronic diabetic wounds. Here, we show that substance P (SP) rescues the malfunctions of dermal fibroblasts in diabetes. SP increased the proliferation of diabetic dermal fibroblasts dose-dependently, although the effect was lower compared to the SP-stimulated proliferation of normal dermal fibroblasts. In contrast to normal dermal fibroblasts, SP increased the expression level of vascular endothelial growth factor (VEGF) and stromal cell-derived factor-1 (SDF-1) in diabetic dermal fibroblast hence, rescuing their angiogenic potential. The cellular characteristics of diabetic dermal fibroblasts modulated by SP would be able to accelerate the wound healing process through faster wound contraction and improved angiogenesis in diabetic chronic wounds. Moreover, SP pretreatment into dermal fibroblasts isolated from diabetic patients would be a promising strategy to develop autologous cell therapy for treating diabetic chronic wounds.

Impaired angiogenesis is a common pathological characteristic of chronic wounds. Therefore, the regulation of angiogenesis is important for proper tissue repair. It was reported that substance P (SP) accelerates wound healing in a skin injury model. SP is degraded by neutral endopeptidase (NEP). Our study shows that systemic co-treatment of SP and thiorphan, an inhibitor of NEP synergically increased the number of α-smooth muscle actin positive-blood vessels in skin wounds. However, there was no synergic improvement in wound contraction and extracellular matrix deposition. Therefore, inhibition of endogenous NEP activity by thiorphan treatment might modulate the effects of SP treatment specifically on accelerating angiogenesis during wound healing. However, the molecular mechanism(s) of the synergic increase in angiogenesis by SP and thiorphan treatment is still unknown.

OBJECTIVES: To develop and validate a self-reported sunlight exposure questionnaire (SEQ) for urban adult Filipinos. METHODS: The study included adults (19–76 years old) in Metro Manila, Philippines, well-versed in the Filipino (Tagalog) language and had resided in Metro Manila for at least 1 year. Exclusion criteria included pregnancy, active skin disorders, and immunocompromised states. An expert panel created a questionnaire in Likert-scale format based on a conceptual framework and 4 existing instruments. The study proceeded in 4 phases: questionnaire item development, translation and back-translation, pretesting, and construct validity and reliability testing using factor analysis, the Cronbach alpha coefficient, and the paired t-test. RESULTS: A 25-item, self-administered, Filipino (Tagalog) SEQ answerable using a 4-point Likert scale was created. The questionnaire was administered to 260 adult participants twice at a 2-week interval, with all participants completing both the first and second rounds of testing. All questionnaire items possessed adequate content validity indices of at least 0.86. After factor analysis, 3 questionnaire domains were identified: intensity of sunlight exposure, factors affecting sunlight exposure, and sun protection practices. Internal consistency was satisfactory for both the overall questionnaire (Cronbach alpha, 0.80) and for each of the domains (Cronbach alpha, 0.74, 0.71, and 0.72, respectively). No statistically significant differences were observed in the responses between the first and second rounds of testing, indicating good test-retest reliability. CONCLUSIONS: We developed a culturally-appropriate SEQ with sufficient content validity, construct validity, and reliability to assess sunlight exposure among urban adult Filipinos in Metro Manila, Philippines.
