Abstract
BACKGROUND Active surveillance systems for monitoring vaccine safety among pregnant women address some of the limitations of a current passive surveillance approach utilized in low- and middle-income countries (LMIC). However, few active surveillance systems in LMIC exist. Our study assessed the feasibility of utilizing three existing data collection systems in Kenya for active surveillance of maternal immunization and to assess the applicability of Global Alignment of Immunization Safety Assessment in pregnancy (GAIA) case definitions that were initially developed for clinical trials within these systems. METHODS We assessed applicability of GAIA case definition for maternal Tetanus Toxoid exposure, stillbirth, low birth weight, small for gestational age, Neonatal Invasive Blood Stream Infection (NIBSI), prematurity and neonatal death in two routine web-based health information systems (Kenya EMR and DHIS-2), and a web-based population-based pregnancy research platform (ANCOV1) in Kenya. RESULTS All three HIS were capable of reporting selected outcomes to varying degrees of GAIA certainty. The ANCOV platform was the most robust in collecting and collating clinical data for effective maternal pharmacovigilance. The utilization of facility- and district-aggregated data limits the usefulness of DHIS-2 in pharmacovigilance as currently operationalized. While the Kenya EMR contained individual level data and meets the key considerations for effective pharmacovigilance, it was used primarily for HIV care and treatment records in a small proportion of health facilities and would require additional resources to expand to all antenatal care facilities and to link maternal and infant records. DISCUSSION Population-based research studies may offer a responsive short-term option for implementing maternal vaccine pharmacovigilance in LMICs. However, the foundation exists for long-term capacity building within the national health electronic data systems to provide this critical service as well as ensure participation of the country in international studies on maternal vaccine safety.

Abstract
BACKGROUND Racial and ethnic disparities in health care exist and are rooted in long-standing systemic inequities. These disparities result in significant excess health care expenditures and are due to complex interactions between patients, health care providers and systems, and social and environmental factors. In perinatal care, these inequities also exist, with Black patients being 3 to 4 times more likely to die of childbirth compared with White patients. Similar health care inequities may also exist in the Military Health System despite universal health care coverage, stable employment, and social programs that benefit military families. OBJECTIVE This study aimed to evaluate racial disparities in obstetrical outcomes in the Military Health System. STUDY DESIGN This is a retrospective cohort study of deliveries from 2019 to 2021 in the Military Health System, which provides obstetrical care for approximately 35,000 annual deliveries. The study was conducted using National Perinatal Information Center data on cesarean delivery, postpartum hemorrhage, and severe maternal morbidity by race and ethnicity from direct-care military hospitals representing tertiary care medical centers and community hospitals in the United States and abroad. Chi-square analyses and binary logistic regression were used to compare groups. RESULTS The cohort included 68,918 deliveries. Of these, 32,358 (47%) were White, 9594 (13.9%) Black, 3120 (4.5%) Asian Pacific Islander, 456 (0.7%) American Indian/Alaska Native, 19,543 (28.4%) other, 3976 (5.8%) unknown, 7096 (10.3%) Hispanic, 58,009 (84.2%) non-Hispanic, and 4399 (6.4%) other ethnicity. Rates of cesarean delivery were significantly higher for Black (30%; odds ratio, 1.44; 95% confidence interval, 1.37-1.52), Asian Pacific Islander (27%; odds ratio, 1.24; 95% confidence interval, 1.14-1.35), and other (26%; odds ratio, 1.20; 95% confidence interval, 1.15-1.25) compared with White race (23%) (P<.001). Postpartum hemorrhage rates were higher for Black (5.9%; odds ratio, 1.11; 95% confidence interval, 1.00-1.24) and Asian Pacific Islander (7.7%; odds ratio, 1.49; 95% confidence interval, 1.29-1.72) compared with White race (5.3%) (P<.001). Severe maternal morbidity was higher for Black (2.9%; odds ratio, 1.44; 95% confidence interval, 1.24-1.67), Asian Pacific Islander (2.9%; odds ratio, 1.45; 95% confidence interval, 1.15-1.82), and other (2.8%; odds ratio, 1.36; 95% confidence interval, 1.21-1.54) compared with White race (2.1%) (P<.001). For severe maternal morbidity excluding blood transfusions, rates were also significantly higher for Black (1%; odds ratio, 1.68; 95% confidence interval, 1.30-2.17) than for White race (0.6%) (P<.002). Hispanic ethnicity was associated with a lower rate of severe maternal morbidity excluding transfusions (0.5%; odds ratio, 0.68; 95% confidence interval, 0.48-0.98) compared with non-Hispanic ethnicity (0.7%) (P=.04). CONCLUSION Racial disparities in obstetrical outcomes exist in the Military Health System despite universal health care coverage, with significantly higher rates of cesarean delivery and severe maternal morbidity in Black, Asian Pacific Islander, and other races compared with White race. These findings suggest that these disparities are likely related to other factors or social determinants of health rather than availability of health care and insurance coverage. Further work should include investigation into such social determinants of health to address their causes, including systemic and structural barriers.

Abstract
BACKGROUND In March 2020, the United Kingdom Multiple Sclerosis Register (UKMSR) established an electronic case return form, designed collaboratively by MS neurologists, to record data about COVID-19 infections in people with MS (pwMS). OBJECTIVES Examine how hospital admission and mortality are affected by disability, age and disease modifying treatments (DMTs) in people with Multiple Sclerosis with COVID-19. METHODS Anonymised data were submitted by clinical teams. Regression models were tested for predictors of hospitalisation and mortality outcomes. Separate analyzes compared the first and second 'waves' of the pandemic. RESULTS Univariable analysis found hospitalisation and mortality were associated with increasing age, male gender, comorbidities, severe disability, and progressive MS; severe disability showed the highest magnitude of association. Being on a DMT was associated with a small, lower risk. Multivariable analysis found only age and male gender were significant. Post hoc analysis demonstrated that factors were significant for hospitalisation but not mortality. In the second wave, hospitalisation and mortality were lower. Separate models of the first and second wave using age and gender found they had a more important role in the second wave. CONCLUSIONS Features associated with poor outcome in COVID-19 are similar to other populations and being on a DMT was not found to be associated with adverse outcomes, consistent with smaller studies. Once in hospital, no factors were predictive of mortality. Reassuringly, mortality appears lower in the second wave.

Abstract
Abstract
Colorectal cancer (CRC) is the second-leading cause of cancer deaths. Mortality could be rapidly reduced through higher uptake and adherence to CRC screening. Information on long-term screening adherence comes from organized programs that lack a comparison group. Objective: Systems of Support to Increase Colorectal Cancer Screening is an ongoing trial testing a centralized mailed and phone-based program to increase long-term CRC screening adherence. We hypothesized that compared to usual care (UC) intervention-arm patients would have more time in compliance with CRC screening guidelines over 5 years. Methods: The setting was an integrated healthcare organization in Washington State. UC included patient-centered medical home with clinic-based strategies to increase screening. Participants included 4675 individuals initially aged 50–74, not current for CRC screening. Intervention arms combined were compared to UC. The primary outcome was the percent of time covered for CRC screening over 5 years of follow-up. Screening tests contributed covered time based on national guidelines for screening intervals. All participants contributed data, but were censored at disenrollment, death, age 76, or CRC diagnosis. Interventions: Patients were randomly assigned to receive UC, or one of three stepped care interventions: 1. Mailings including mailed fecal tests, a call-in number if colonoscopy or sigmoidoscopy was preferred; 2. Mailings plus brief telephone assistance; 3. Mailings and telephone assistance plus nurse navigation. In year 3, intervention group participants still CRC screening-eligible were randomized to stopped or continued mailed interventions only. Results: Compared to UC, intervention participants had 31% more time not in need of CRC testing (adjusted rate ratio, weighted for exposure time 1.31 [1.25–1.37], 47.2% vs. 62.0% covered time) over 5 years. Fecal testing was responsible for almost all additional covered time. Compared to intervention participants, UC individuals were more likely never to have completed any CRC testing over 5 years (17.4% vs. 10.3%, net difference 7.2%, P < 0.001) Conclusions: An organized mail and phone program led to increased CRC screening adherence over 5 years, mainly because of regular fecal testing uptake.

Abstract
IntroductionSurgery for refractory temporal lobe epilepsy can cause postoperative visual field defects (VFD). This study aimed to predict personalised risk of VFDs for patients undergoing selective transsylvian amygdalohippocampectomy.MethodsPreoperative reconstruction of the optic radiations (OR) using diffusion tensor-based tractography was completed on two patients. The ‘average resection model’ uses a template from postoperative structural scans of five patient scans to predict an average resection in the patient. The OR tractography was compared with the resection margins to determine fibre involvement. The ‘multiple individual comparison model’ compared individual postoperative scans with the preoperative tractography to determine risk of VFD.ResultsIn Patient 1 the average resection overlapped the OR, so an average resection would be expected to produce a VFD. In 3/5 postoperative scans the resection intersected with the OR, indicating that 60% of prior resections would have caused a defect. In Patient 2 no overlap between resection and OR was found in either model. Perimetry confirmed VFD in patient 1 but not in patient 2.DiscussionThis pilot study demonstrates that the risk of postoperative VFDs can be predicted. The two models provide qualitatively different form of quantitative risk which could inform the discussion between patient and clinician.

Abstract
OBJECTIVES Evaluate the association of self-reported vasomotor symptom (VMS) frequency with race/ethnicity among a diverse midlife US population and explore menopause symptom differences by dietary soy isoflavone (genistein+daidzein) consumption. STUDY DESIGN Cross-sectional population-based study of peri- and postmenopausal women, ages 45-58. OUTCOMES Recent VMS frequency, VMS ever; recent symptom bother (hot flashes, night sweats, headache and joint-ache). RESULTS Of 18,500 potentially eligible women, 9325 returned questionnaires (50.4% response); 3691 were excluded (premenopausal, missing data, taking hormones). Of 5634 remaining women, 82.1% reported hot flashes ever, 73.1% reported night sweats ever; 48.8% and 38.6% reported recent hot flashes or night sweats, respectively. Compared with White women, Chinese, Japanese, Vietnamese, other Asian (each p<0.001) and Filipino (p<0.01) women less commonly reported ever having hot flashes; Asian women less commonly reported recent VMS bother (p<0.001). Black women more commonly reported hot flashes ever (p<0.05) and recent VMS bother (p<0.05). Compared with non-Hispanic White women, Hispanic women were less likely to report hot flashes (p<0.05) or night sweats (p<0.001) ever. Women were classified by isoflavone consumption: (1) none (n=1819), (2) 0.01-4.30 mg/day (n=1931), (3) 4.31-24.99 mg/day (n=1347) and (4) ≥ 25 mg/day (n=537). There were no group differences in recent VMS number/day: (1) 7.0 (95% CI 6.5, 7.5); (2) 6.4 (95% CI 6.0, 7.1); (3) 7.0 (95% CI 6.3, 8.2); and (4) 6.8 (95% CI 6.1, 7.7). CONCLUSIONS Menopausal symptoms, independent of isoflavone intake, varied considerably by race/ethnicity and were least common among Asian races.

Most cases of acute leukemia can be assigned to the myeloid, B or T lineage. In a few cases, definitive assignment cannot be achieved because blasts express antigens of more than one lineage. A subset of these, referred to as acute bilineal leukemias (aBLLs), is characterized by the presence of more than one population of blasts, each comprising a single lineage. We identified 19 cases of aBLL, including 10 mixed T and myeloid (T-My) and nine mixed B and myeloid (B-My); no mixed B and T cases were identified. Cytogenetic data were available for 16 patients. Three of seven patients with B-My had a t(9;22)(q34q11.2), two had 11q23 translocations and one had del(9). Two of nine patients with T-My had 2p13 translocations; five had other unrelated abnormalities. Of 16 patients with outcome data, only six achieved complete remission and only two remain free of disease 2.5 and 4.5 years after chemotherapy or stem cell transplantation. aBLL is a rare disease that combines B or T and myeloid blasts. Cytogenetic abnormalities of t(9;22) and 11q23 are common in, and may be restricted to, B-My cases, while T-My cases have frequent but generally non-recurring abnormalities. Both types of aBLL are associated with poor outcome.

Abstract
Vaccination against nicotine is being studied as a potential treatment for nicotine dependence. Some of the limitations of vaccination, such as variability in antibody titer and affinity, might be overcome by instead using passive immunization with nicotine-specific monoclonal antibodies. The effects of antibodies on nicotine distribution to brain were studied using nicotine-specific monoclonal antibodies (NICmAbs) with K(d) values ranging from 60 to 250 nM and a high-affinity polyclonal rabbit antiserum (K(d) = 1.6 nM). Pretreatment with NICmAbs substantially increased the binding of nicotine in serum after a single nicotine dose, reduced the unbound nicotine concentration in serum, and reduced the distribution of nicotine to brain. Efficacy was directly related to antibody affinity for nicotine. Efficacy of the highest affinity NICmAb, NICmAb311, was dose-related, with the highest dose reducing nicotine distribution to brain by 78%. NICmAb311 decreased nicotine clearance by 90% and prolonged the terminal half-life of nicotine by 120%. At equivalent doses, NICmAb311 was less effective than the higher affinity rabbit antiserum but comparable efficacy could be achieved by increasing the NICmAb311 dose. These data suggest that passive immunization with nicotine-specific monoclonal antibodies substantially alters nicotine pharmacokinetics in a manner similar to that previously reported for vaccination against nicotine. Antibody efficacy is a function of both dose and affinity for nicotine.

Abstract
The risk of chemotherapy-induced infertility in male and female germ cell tumour (GCT) survivors is unclear, but may correlate with cisplatin dose. Here, we examine a large series of GCT patients for the effect of chemotherapy on those attempting to have children. Our GCT database was screened for nonseminomatous GCT patients who had (1) received POMB/ACE chemotherapy (cisplatin, vincristine, methotrexate, bleomycin alternating with actinomycin D, cyclophosphamide and etoposide) and (2) stage I male GCT patients who were untreated between 1977 and 1996. Fertility was assessed by questionnaire and medical records. A total of 64 of 153 treated and 35 of 115 untreated men attempted to have children. In all, 28% (18 out of 64) receiving POMB/ACE were unsuccessful. Radiotherapy (six), atrophic remaining testis (one) or prior infertility (three) were implicated in 10 cases, so chemotherapy-induced infertility may have occurred in only 11% (eight out of 64). Strikingly, 26% (nine out of 35) of untreated stage I patients also failed to have children (three had radiotherapy, three prior infertility). Moreover, in treated men, no association was seen between cisplatin dose and infertility. In contrast, radiotherapy significantly increased male infertility (P=0.001). Of 28 treated women who attempted to have children, 25% (seven out of 28) were unsuccessful. One previously had infertility and one subsequently had successful IVF so chemotherapy-induced infertility potentially occurred in only 18% (five out of 28) and was not related to cisplatin dose. In conclusion, the risk of chemotherapy-induced infertility is low in both male and female GCT patients and does not clearly correlate with the cumulative cisplatin dose.

Abstract
A recombinant Fab antibody, designated 1E8-4b, which reacts with the Alzheimer's disease (AD)-related Abeta peptides, Abeta[1-40], Abeta[1-42] and Abeta[1-43] has been developed. The 1E8-4b Fab was constructed by cloning the V(H)C(H1) and V(L)C(L) domains from the parent hybridoma 1E8 antibody, reported previously to recognize these Abeta peptides. Briefly, a C-terminal Flag tag sequence was incorporated into this construct, which was ligated into the vector pHFA2 and expressed in Escherichia coli. Following purification on an M2 anti-Flag affinity column, the 1E8-4b recombinant Fab antibody was shown to bind plaques within sections of brain tissue from CERAD-defined AD patients by immunohistochemistry. ELISA, epitope mapping and immunoblotting confirmed the recognition of the Abeta1-40/42/43] peptides by the 1E8-4b Fab. The 1E8-4b Fab did not recognize APP695 or APP770 which contain the Abeta sequence. The Abeta specificity of the recombinant 1E8-4b Fab antibody was identical to the parent 1E8 monoclonal antibody.

Abstract
Little literature exists on the safety of early pregnancy following chemotherapy. Here we assess the rate of relapse and foetal outcome in women who have completed single and multi-agent chemotherapy for gestational trophoblastic tumours. The records of 1532 patients treated for persistent gestational trophoblastic tumours at Charing Cross Hospital between 1969 and 1998 were reviewed. Patients were defined as receiving single agent or multi-agent treatment. Relapse rates and foetal outcome were reviewed in the 230 patients who became pregnant within 12 months of completing chemotherapy. In the single agent group 153 (22%) of 691 patients conceived early. Three subsequently relapsed. In the multi-agent group, 77 (10%) of 779 patients conceived early, two then relapsed. Relapse rates were 2% (3 out of 153) and 2.5% (2 out of 77) for each group compared to 5% and 5.6% in the comparative non-pregnant groups. Outcomes of 230 early pregnancies: 164 (71%) delivered at full term, 35 (15%) terminations, 26 (11%) spontaneous abortions, three (1.3%) new hydatidiform moles and two (1%) stillbirths. Early pregnancies were more common in the single agent group (P<0.001), but spontaneous miscarriages and terminations were more likely to occur in the multi-agent group (P=0.04 and 0.03, respectively). Of the full-term pregnancies, three (1.8%) babies were born with congenital abnormalities. Patients in either group who conceive within 12 months of completing chemotherapy are not at increased risk of relapse. Though, we still advise avoiding pregnancy within 12 months of completing chemotherapy, those that do conceive can be reassured of a likely favourable outcome.

Abstract
Increasing emphasis is now being placed upon the evaluation of health service interventions to demonstrate their effects. A series of effectiveness reviews of the oral health education and promotion literature has demonstrated that many of these interventions are poorly and inadequately evaluated. It is therefore difficult to determine the effectiveness of many interventions. Based upon developments from the field of health promotion research this paper explores options for improving the quality of oral health promotion evaluation. It is essential that the methods and measures used in the evaluation of oral health promotion are appropriate to the intervention. For many oral health promotion interventions clinical measures and methods of evaluation may not be appropriate. This paper outlines an evaluation framework which can be used to assess the range of effects of oral health promotion programmes. Improving the quality of oral health promotion evaluation is a shared responsibility between researchers and those involved in the provision of programmes. The provision of adequate resources and training are essential requirements for this to be successfully achieved.

Abstract
Assembly of infectious human immunodeficiency virus type 1 (HIV-1) proceeds in two steps. Initially, an immature virus with a spherical capsid shell consisting of uncleaved Gag polyproteins is formed. Extracellular proteolytic maturation causes rearrangement of the inner virion structure, leading to the conical capsid of the infectious virus. Using an in vitro assembly system, we show that the same HIV-1 Gag-derived protein can form spherical particles, virtually indistinguishable from immature HIV-1 capsids, as well as tubular or conical particles, resembling the mature core. The assembly phenotype could be correlated with differential binding of the protein to monoclonal antibodies recognizing epitopes in the HIV-1 capsid protein (CA), suggesting distinct conformations of this domain. Only tubular and conical particles were observed when the protein lacked spacer peptide SP1 at the C-terminus of CA, indicating that SP1 may act as a molecular switch, whose presence determines spherical capsid formation, while its cleavage leads to maturation.

Abstract
Hypersensitivity reactions to 6-mercaptopurine (6-MP) or azathioprine occur during the treatment of inflammatory bowel disease (IBD), raising significant diagnostic and therapeutic challenges. Charts of 591 patient with IBD treated with 6-MP in a single center were retrospectively reviewed. All allergic reactions were recorded along with results of rechallenge, desensitization, and subsequent course of IBD. Sixteen (2.7%) allergic reactions to 6-MP were noted, with fever being the most common (14 cases). Nine of these were rechallenged with 6-MP with recurrence of the same symptoms. Azathioprine was tried in six patients and in five the same symptoms recurred. Four patients underwent successful desensitization to either 6-MP or azathioprine; all four plus another patient who tolerated direct switch to azathioprine entered long-term remission. Among the remaining 11, 5 required surgery, 2 are well on methotrexate, and 4 have chronic symptoms while being treated with other medications. If an allergic reaction to 6-MP occurs during the treatment of IBD, direct switching to azathioprine is probably not justified. Instead, desensitization to either 6-MP or azathioprine should be attempted. Patients who can tolerate these medications after previous allergic reactions have improved outcomes compared with patients who resort to other forms of treatment.

Abstract
Capsular polysaccharide (CP) conjugate vaccines targeting a variety of bacterial infections are currently under development and clinical evaluation. The inclusion of multiple CP serotypes combined in a single injection is an important maneuver being evaluated. The combination of CP conjugate vaccines into a single multivalent injection may result in competition among the different components and adversely affect the immunogenicity of any individual conjugate. We observed a reduction of 30-90% in antibody responses to several serotypes in mice when immunogenicity of a 12-valent Escherichia coli (E. coli) lipopolysaccharide (LPS) conjugate vaccine was compared to the immunogenicity of each monovalent vaccine evaluated separately. A reduction of 30% was observed in the Staphylococcus aureus (S. aureus) type 8 CP antibodies when a type 8-rEPA conjugate was combined with a type 5-rEPA conjugate. S. aureus types 5 and 8-rEPA conjugates were combined with 100 micrograms of either rEPA (homologous) or diphtheria toxoid (DT) (heterologous) carrier proteins, and evaluated in rEPA or DT primed mice. The addition of the homologous protein resulted in a 64% reduction in type 5 CP antibodies. The heterologous protein did not affect the immunogenicity of the type 5. We postulate that the free protein competed with the conjugate and recruited most of the rEPA primed T cells. In the case of the DT conjugates, the DT targeted different populations of the T cells, thus interference was not observed. These data suggested that the epitopic load rather than the antigenic load at the site of injection caused reduced immunogenicity of the conjugates. We theorize that individual components of multivalent CP vaccines conjugated to the same carrier proteins would compete for a limited number of specific carrier protein primed T cells. This would result in one or more components being unavailable in eliciting a sufficient immune response. The use of multiple carrier proteins should be considered as an approach to reduce interference when multivalent conjugate vaccines are to be formulated into a single injection.

Abstract
This project aims to clarify the phylogenetic relationships among the extant species of Varanus in order to elucidate the origins of Varanidae, using DNA sequences. Results obtained for a minimum of 662 nucleotides of 12S rRNA sequence data from each of 21 extant species of Varanus indicate that the Australian varanids form a single monophyletic clade and also suggest that within the Australian varanids, members of the subgenus Odatria (pygmy monitors) may from a clade separate from those in the subgenus Varanus (large monitors). The Asian species appear to be sister taxa to the Australian species, while the two African species investigated were most divergent, suggesting that the Varanidae are not Gondwanic in origin. Hypothesis testing analyses were performed and involved constraining the 12S sequence data according to previously described topologies and testing the difference using parametric and nonparametric statistics. The phylogeny generated using 12S sequence data was statistically different from previously described morphological trees, while there was some support for topologies based on chomosomal and immunological datasets. Overall, our results suggest that the Australian species may be derived from an Asian source and are, therefore, in agreement with the hypothesis based on the fossil record suggesting that Varanidae may be Asian in origin.

Abstract
In an in vitro system that mimics the assembly of immature human immunodeficiency virus (HIV) particles, ordered arrays of HIV-1 capsid (CA) proteins encoded by the viral gag gene have been obtained by incubation of histidine-tagged capsid proteins (His-HIVCA) beneath lipid monolayers containing the nickel-chelating lipid, 1,2-di-O-hexadecyl-sn-glycero-3-(1'-2"-R-hydroxy-3'-N-(5-amino-1- carboxypentyl)iminodiacetic acid)propyl ether. The membrane-bound His-HIVCA proteins formed small crystalline arrays of primitive (p1) unit cells with dimensions of a = 74.2 A, b = 126.2 A, gamma = 89.3 degrees. The image-analyzed two-dimensional projection of His-HIVCA assemblies shows a cage-like lattice, consisting of hexamer and trimer units, surrounding protein-free cage holes. The hexamer-coordinated cage holes of 26.3-A diameter are spaced at 74. 2-A intervals: these distances, and the hexamer-trimer arrangement, are consistent with previous, lower resolution studies on immature HIV-1 virus particles produced in vivo. Additionally, HIV-1 matrix protein trimer unit structures align to the His-HIVCA trimer units such that residues previously shown to interact with the HIV-1 gp120/gp41 envelope protein complex are oriented toward the hexamer cage holes. Our results form a bridge between results from conventional methods for the analysis of HIV particle structure.
