Abstract
IMPORTANCE Dyspnoea and hypoxia in pregnant women during the COVID-19 pandemic may be due to causes other than SARS Co-V-2 infection which should not be ignored. Shared decision-making regarding early delivery is paramount. OBJECTIVE To highlight and discuss the differential diagnoses of dyspnoea and hypoxia in pregnant women and to discuss the risks versus benefit of delivery for maternal compromise. DESIGN, SETTING AND PARTICIPANTS Case series of two pregnant women who presented with dyspnoea and hypoxia during the COVID-19 pandemic. RESULTS Two pregnant women presented with dyspnoea and hypoxia. The first case had COVID-19 infection in the 3rd trimester. The second case had an exacerbation of asthma without concurrent COVID-19. Only the first case required intubation and delivery. Both recovered and were discharged home. Conclusion and relevance: Our two cases highlight the importance of making the correct diagnosis and timely decision-making to consider if delivery for maternal compromise is warranted. Whilst COVID-19 is a current healthcare concern other differential diagnoses must still be considered when pregnant women present with dyspnoea and hypoxia.

Abstract
BACKGROUND Haemolytic disease of the fetus and newborn (HDFN) occurs when maternal IgG alloantibodies to fetal red blood cell antigens cross the placenta, causing haemolysis in the fetus and/or neonate. After delivery, the main concern is hyperbilirubinaemia, which can cause neurological damage. OBJECTIVES To summarise our current management and outcome data to inform health-care professionals counselling women whose pregnancies are at risk of HDFN and to compare these data with relevant studies. METHODS This is a retrospective descriptive study of all high-risk pregnancies at risk of HDFN at Guy's and St. Thomas' NHS Foundation Trust (GSTFT) Maternity Unit over a 7-year period. We defined high-risk pregnancies as those in whom anti-D, anti-c, anti-K or high (>32 or doubling strength) titres of all other antibodies were identified. RESULTS A total of 130 pregnancies in 112 women were followed up. A single alloantibody was found in 93 pregnancies (71.5%) and multiple alloantibodies in 37 pregnancies (28.5%). Anti-D was most commonly encountered (n = 48, 36.9%), followed by anti-c (n = 31, 23.8%) and anti-E (n = 15, 11.5%). In 65 of 130 pregnancies (50%), antibody concentrations triggered scans to screen for fetal anaemia. Of 130 pregnancies, 6 (4.6%) required intrauterine transfusions, and 31 of 130 (26%) neonates required post-natal intervention. Overall, morbidity was 0.1% and mortality 0.002%. CONCLUSIONS This study demonstrates that morbidity and mortality caused by HDFN is minimal. These results are reassuring for women at risk of HDFN as even severely affected cases are successfully managed in most instances. Further studies are needed to identify predictors of disease severity.

Abstract
OBJECTIVE There are limited data for counseling on and management of periviable small-for-gestational-age (SGA) fetuses. We therefore aimed to investigate the short-term outcome of periviable SGA fetuses in relation to the likely underlying cause. METHODS This was a retrospective study of data from three London tertiary fetal medicine centers obtained between 2000 and 2015. We included viable singleton pregnancies with a severely small fetus, defined as those with an abdominal circumference ≤ 3rd percentile, identified between 22 + 0 and 25 + 6 weeks' gestation. Data obtained included fetal biometry, presence of placental anomalies, uterine and fetal Doppler and neonatal outcome. We excluded cases with structural abnormalities, proven or suspected abnormal karyotype or genetic syndromes. Cases were classified according to the suspected underlying cause of the small fetal size into one of the following categories: uteroplacental insufficiency, evidence of placental damage with normal uterine artery Doppler, viral infection, or unclassied. RESULTS There were 245 cases included in the study. Of these, at diagnosis of SGA, 201 (82%) were categorized as uteroplacental cause, 13 (5%) as suspected placental cause, one (0.4%) as suspected viral cause and 30 (12%) could not be assigned to any of these categories. Overall, 101 (41%) cases survived the neonatal period; 89 (36%) underwent in-utero fetal demise, 22 (9%) died neonatally and 33 (14%) pregnancies were terminated. The diagnosis-to-delivery interval was 8.1 weeks in those that survived and 4.5 weeks in those that died neonatally. CONCLUSIONS Almost 90% of periviable SGA cases are associated with uteroplacental insufficiency or intraplacental damage. Survival is related to gestational age at delivery, with outcomes better than might be assumed at diagnosis and some pregnancies reaching term. Copyright © 2016 ISUOG.

Abstract
Abstract
Background: Numerous chemotherapeutic agents are available against breast cancer (BC), but a vast majority of patients diagnosed with this disease still develop treatment resistance and eventually succumb to disease. It remains an unmet need to identify specific molecular defects against which targeted therapy are available for improving clinical outcomes in BC. Our study aims to identify frequent hotspot mutations in BCs and determine their clinical impact.
Methods: 200 women with BC(early diagnosed and/or metastatic) aged 26-75 yrs (median age 50.5yrs) diagnosed at HCG from April 2013-15 were consented to be profiled by targeted deep sequencing for hotspot mutations in 48 cancer-related genes using Illumina's TSCAP panel and MiSeq technology in an IRB-approved prospective study in a CLIA compliant laboratory. All the cases had pathology review for stage, histological type, hormonal status and Ki67. The average coverage across 220 hot spots was greater than 1000X. Data was processed using Strand Avadis NGS™. Mutations identified in the tumor were assessed for 'actionability' i.e. response to therapy and impact on prognosis. Results: Somatic variants were detected in 75% of cases with direct impact on therapy or prognosis. Genetic aberrations were identified in PI3K/AKT/ mTOR signalling pathway in substantial fraction (27%) of breast cancer cases, out of which 17% had PIK3CA activating mutations,13 and 5 cases had PTEN and AKT deletions or truncating mutations respectively. Aberration in this pathway was more prevalent in HR+ve (53%) and HER2-ve including TNBC (61%) than in HR+/HER2+ve tumors (10.6%) of IDC histology. However, no correlation was found with stage and Ki67 index of the tumor. Notably 80% of BC cases presented with liver metastasis at the time of diagnosis were detected with PIK3CA mutation indicating its role as a surrogate marker of organ specific metastasis. PIK3CA was found to be co mutated with p53 in 16 cases (9%) of which 4 cases showed npCR post NACT. Also disruptive and non-disruptive mutations in TP53 alone were found in 25% of BC, varying widely among different histologies. A follow up of few cases showed shorter PFS and poor outcome in resected BC treated with NACT indicating its robust prognostic value in NACT setting. Furthermore, two patients were detected with cKIT mutations indicating sensitivity to imatinib and therefore enrolled on a clinical trial. The other variants were found in RB1(n=8),Her2 (n=2),FGFR amplification(n=1), KRAS(n=2),NRAS(n=3)CDH1(n=1),FBXW7(n=2) and EGFR(n=1).All these variants detected indicated resistance to conventional therapy and suggested sensitivity to available targeted therapy, either approved or in clinical trials. The response and outcome are being monitored in about 20 (10%) patients who have been enrolled in clinical trials and receiving mutation specific targeted therapy. Conclusions: This study confirms the utility of multigene profiling in early diagnosed and advanced BC patients, to stratify them on their molecular profile who could potentially benefit from targeted therapy. Prospective studies and randomized clinical trials are ongoing to confirm the independent prognostic and therapeutic value of the mutations in a larger cohort of Indian population.

Abstract
This paper deals with a systematic hydrogeological, geophysical, and hydrochemical investigations carried out in SIPCOT area in Southern India to demarcate groundwater pollution and saline intrusion through Uppanar River, which flows parallel to sea coast with high salinity (average TDS 28, 870 mg/l) due to back waters as well as discharge of industrial and domestic effluents. Hydrogeological and geophysical investigations comprising topographic survey, self-potential, multi-electrode resistivity imaging, and water quality monitoring were found the extent of saline water intrusion in the south and pockets of subsurface pollution in the north of the study area. Since the area is beset with highly permeable unconfined quaternary alluvium forming potential aquifer at shallow depth, long-term excessive pumping and influence of the River have led to lowering of the water table and degradation of water quality through increased salinity there by generating reversal of hydraulic gradient in the south. The improper management of industrial wastes and left over chemicals by closed industries has led surface and subsurface pollution in the north of the study area.

Abstract
OBJECTIVES To study the frequency and clinical significance of crown-rump length (CRL) discrepancy at 11-14 weeks of gestation in twin pregnancies from an unselected population. METHODS This was a retrospective analysis of all twin pregnancies that underwent a routine 11-14-week scan at a large teaching hospital. Fetal loss was defined as fetal demise of one or both twins after 14 weeks. RESULTS A total of 507 twin pregnancies were studied; 382 (75.3%) were dichorionic and 125 (24.7%) were monochorionic twins. The discrepancy in CRL was expressed as a percentage of the CRL of the larger twin. The 95(th) and 99(th) centile for CRL discrepancy in twins was 12.2% and 19.3%, respectively. The discrepancy in CRLs in monochorionic and dichorionic twins was not significantly different (Mann-Whitney U = 22,406, P = 0.302). In 39 twin pairs, there was subsequent intrauterine death of one or both twins. Fetal loss was more common in monochorionic twins (24/125) than in dichorionic twins (15/382) (chi-square = 30.9, P < 0.001). In monochorionic twins, the discrepancy in CRLs in the 24 cases with subsequent loss was significantly greater than in the 101 twin pairs with no subsequent loss (Mann-Whitney U = 896, P = 0.048). The discrepancy in CRLs in 15 dichorionic twins with subsequent loss was not different from that in the 367 twins with no loss (Mann-Whitney U = 2116.5, P = 0.129). The CRL discrepancy was significantly correlated with birth-weight discordance in twins (Spearman's rho = 0.128, P = 0.006). However, this was due to a significant correlation in dichorionic twins (Spearman's rho = 0.127, P = 0.016) but not in monochorionic twins (Spearman's rho = 0.145, P = 0.14). CONCLUSIONS Fetal loss is significantly associated with discrepancy in CRL at the 11-14-week scan in monochorionic twins and discordance in birth weights is significantly associated with discrepancy in CRL in dichorionic twins. However, intertwin CRL discrepancy is of limited value in screening for these adverse events.

Abstract
BACKGROUND The development of susceptibility to secondary pathogenic infections in the oral cavity during HIV infection is likely to result from or coincide with deterioration of the local mucosal immune system. METHODS We have utilized the SIV model to investigate the kinetics and magnitude of oral pathogenesis during systemic dissemination of intravenously inoculated SIVmac251. RESULTS Viral replication was detected in oropharyngeal lymph nodes at 6 weeks post-infection and shown to be coincident with a broad scale loss of growth factor receptor transcription in the oral mucosa, providing multiple avenues for blocking the normal activity of apoptosis inhibitors that function through Bcl2- and p53-dependent pathways. CONCLUSIONS Our findings suggest that the normal balance between cell death and regeneration may be rapidly disrupted in the oral mucosa during the early stages of immunodeficiency virus infection, setting the stage for continuing deterioration of immune function and the development of susceptibility to secondary infections.
