Abstract
The concept of 'Hallmarks of Cancer' is an approach of reducing the enormous complexity of cancer to a set of guiding principles. As the underlying mechanism of cancer are portrayed, we find that we gain insight and additional aspects of the disease arise. The understanding of the tumor microenvironment (TME) brought a new dimension and led to the discovery of novel hallmarks such as senescent cells, non-mutational epigenetic reprogramming, polymorphic microbiomes and unlocked phenotypic plasticity. Circular RNAs (circRNAs) are single-stranded, covalently closed RNA molecules that are ubiquitous across all species. Recent studies on the circRNAs have highlighted their crucial function in regulating the formation of human malignancies through a range of biological processes. The primary goal of this review is to clarify the role of circRNAs in the most common form of liver cancer, hepatocellular carcinoma (HCC). This review also addressed the topic of how circRNAs affect HCC hallmarks, including the new generation hallmarks. Finally, the enormous applications that these rapidly expanding ncRNA molecules serve in the functional and molecular development of effective HCC diagnostic biomarkers and therapeutic targets.

Abstract
INTRODUCTION Research into patient and public views on predictive software and its use in healthcare is relatively new. This study aimed to understand older adults' acceptability of an opportunistic bone density assessment for osteoporosis diagnosis (IBEX BH), views on its integration into healthcare, and views on predictive software and AI in healthcare. METHODS Focus groups were conducted with participants aged over 50 years, based in South West England. Data were analysed using thematic analysis. Analysis was informed by the theoretical framework of acceptability. RESULTS Two focus groups were undertaken with a total of 14 participants. Overall, the participants were generally positive about the IBEX BH software, and predictive software's in general stating 'it sounds like a brilliant idea'. Although participants did not understand the intricacies of the software, they did not feel they needed to. Concerns about IBEX BH focussed more on the clinical indications of the software (e.g. more scans or medications), with participants expressing less trust in results if they indicated medication. Questions were also raised about how and who would receive the results of this software. Individual choice was evident in these discussions, however most indicated the preferences for spoken communication 'But I would expect that these results would be given by a human to another human.' CONCLUSIONS Focus group participants were generally accepting of the use of predictive software in healthcare. IMPLICATIONS FOR PRACTICE Thought and care needs to be taken when integrating predictive software into practice. Focusses on empowering patients, providing information on processes and results are key.

Abstract
BACKGROUND AND AIMS The Portsmouth-Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (P-POSSUM) is one of the scores that is used most frequently for determining the likelihood of mortality in patients undergoing emergency laparotomy. National Emergency Laparotomy Audit (NELA) presents a novel and validated score. Therefore, we aimed to compare the performance of the NELA and P-POSSUM mortality risk scores in predicting 30-day and 90-day mortality in patients undergoing emergency laparotomy. METHODS Between August 2020 and October 2022, this cohort study was undertaken at Menoufia University Hospital. We compared the P-POSSUM, preoperative NELA, and postoperative NELA scores in patients undergoing emergency laparotomy. All variables needed to calculate the used scores were collected. The outcomes included the death rates at 30 and 90 days. By calculating the area under the curve (AUC) for every mortality instrument, the discrimination of the various methods was evaluated and compared. RESULTS Data from 670 patients were included. The observed risk of 30-day and 90-day mortality was 10.3% (69/670) and 13.13% (88/670), respectively. Concerning 30-day mortality, the AUC was 0.774 for the preoperative NELA score, 0.763 for the preoperative P-POSSUM score, and 0.780 for the postoperative NELA score. Regarding 90-day mortality, the AUCs for the preoperative NELA score, preoperative P-POSSUM score, and postoperative NELA score were 0.649 (0.581-0.717), 0.782 (0.737-0.828), and 0.663 (0.608-0.718), respectively. There was noticeable difference in the three models' capacity for discrimination, according to pairwise comparisons. CONCLUSIONS The probability of 30-day and 90-day death across the entire population was underestimated by the NELA and P-POSSUM scores. There was discernible difference in predictive performance between the two scores.

Abstract
Metastasis is the principal cause of cancer death, yet we lack an understanding of metastatic cell states, their relationship to primary tumor states, and the mechanisms by which they transition. In a cohort of biospecimen trios from same-patient normal colon, primary and metastatic colorectal cancer, we show that while primary tumors largely adopt LGR5 + intestinal stem-like states, metastases display progressive plasticity. Loss of intestinal cell states is accompanied by reprogramming into a highly conserved fetal progenitor state, followed by non-canonical differentiation into divergent squamous and neuroendocrine-like states, which is exacerbated by chemotherapy and associated with poor patient survival. Using matched patient-derived organoids, we demonstrate that metastatic cancer cells exhibit greater cell-autonomous multilineage differentiation potential in response to microenvironment cues than their intestinal lineage-restricted primary tumor counterparts. We identify PROX1 as a stabilizer of intestinal lineage in the fetal progenitor state, whose downregulation licenses non-canonical reprogramming.

Abstract
PURPOSE To compare the macular and papillary parameters on optical coherence tomography (OCT) between the amblyopic eye and the healthy eye in subjects with unilateral strabismic or anisometropic amblyopia. PATIENTS AND METHODS This is a cross-sectional and comparative study carried out over two years, from April 1, 2019, to March 31, 2021. We included patients aged over 5years, followed for unilateral amblyopia, free of any neurological and/or ocular pathology. The evaluation of the macular and papillary parameters in the amblyopic and healthy eyes was performed with Swept-Source Optical Coherence Tomography (OCT-SS). The parameters were compared according to age group and type of amblyopia. RESULTS We collected 50 patients, 29 children, and 21 adults, with a mean age of 19.8years. Amblyopia was secondary to anisometropia in 40 patients and strabismus in 10 patients. Analysis of macular tomographic parameters found no significant difference between amblyopic eyes and healthy eyes for mean macular thickness (P=0.86), central macular thickness (P=0.86), or mean macular volume (P=0.54). The mean retinal peripapillary fiber thickness (RNFL) was 107.48μm in the amblyopic eye and 103.8μm in the healthy eye, with a statistically significant difference (P<0.001). This significant thickening of the RNFL in amblyopic eyes was present in adults (P<0.001), children (P<0.001), anisometropic (P<0.001), and strabismic amblyopia (P=0.024). Analysis of the other optic nerve head parameters revealed no significant difference between amblyopic eyes and healthy eyes in terms of optic disc surface area (P=0.89), neuro-retinal annulus surface area (P=0.47), vertical (P=0.98) or horizontal (P=0.74) cup to disc ratio. CONCLUSION Amblyopia is accompanied by thickening of the peripapillary retinal fibers without macular repercussions. However, larger prospective studies are needed to confirm these results.

Abstract
PURPOSE A preoperative estimate of the risk of malignancy for intraductal papillary mucinous neoplasms (IPMN) is important. The present study carries out an external validation of the Shin score in a European multicenter cohort. METHODS An observational multicenter European study from 2010 to 2015. All consecutive patients undergoing surgery for IPMN at 35 hospitals with histological-confirmed IPMN were included. RESULTS A total of 567 patients were included. The score was significantly associated with the presence of malignancy (p < 0.001). In all, 64% of the patients with benign IPMN had a Shin score < 3 and 57% of those with a diagnosis of malignancy had a score ≥ 3. The relative risk (RR) with a Shin score of 3 was 1.37 (95% CI: 1.07-1.77), with a sensitivity of 57.1% and specificity of 64.4%. CONCLUSION Patients with a Shin score ≤ 1 should undergo surveillance, while patients with a score ≥ 4 should undergo surgery. Treatment of patients with Shin scores of 2 or 3 should be individualized because these scores cannot accurately predict malignancy of IPMNs. This score should not be the only criterion and should be applied in accordance with agreed clinical guidelines.

Abstract
Perforated peptic ulcer (PPU) treatment guidelines are still up for discussion. Due to the morbidity and mortality linked to each, the use of both operative and non-operative management, including conservative and endoscopic treatment, is still debatable. A standardized protocol has been used to write a best evidence topic. The discussion focused on whether operative management for PPU is preferable to non-operational management or vice versa. MEDLINE, the Cochrane Library, Scopus, and the Web of Science were the databases used to conduct an electronic search of the pertinent literature. We found 56 articles, out of these only 5 studies were found to be appropriate to answer the question. The outcome assessed was failure of management. The best evidence showed that both operative and non-operative management can be used with similar outcomes depending on the patient selection for each category. Operative versus non-operative management of perforated peptic ulcer disease. •Non-operative management is reserved for selective patients for perforated peptic ulcer. •Endoscopic treatment and interventional radiology can serve as a bridge between conservative and surgical management

Abstract
Abstract
Aims
Within the first 48 hours (h) of trauma, hyper-coagulation state occurs which put trauma patients at risk of developing deep vein thrombosis (DVT) and pulmonary embolism (PE), leading to an increase rate of mortality. Non operative management (NOM) is now the standard of care for traumatic splenic injuries (TSI). However, timing of initiating chemical venous thromboembolism (VTE) prophylaxis, heparin or low molecular weight heparin (LMWH), remains controversial due to concern of rebleeding. This study examines the safety and timing of initiating VTE prophylaxis post TSI.
Methods
Patients with TSI were identified from prospectively maintained Trauma Audit and Research Network (TARN) database from 2015–2020 in a single tertiary trauma centre. Clinical and radiological information were collected retrospectively. TSI were graded using AAST classification. VTE prophylaxis initiation were categorised as not given, <48h and >48h following the injury.
Results
In total 102 patients were included. Fifty-three percent (54/102) had Grade 3 injury and above. Majority 90/102 (88%) of patients were treated non-operatively. VTE prophylaxis was not given for 31 (30.4%), initiated for 37 (36.3%) within 48h and given to 34 (33.3%) patients after 48h. Seven (7%) patients developed thromboembolic events, majority of which (6/7) received VTE prophylaxis after 48h. None of the patients who received VTE prophylaxis had rebleeding.
Conclusions
This study showed that early initiation of chemical VTE prophylaxis (<48h) is safe, resulted in lower incidence of DVTs/PEs without increase risk of bleeding. Results from this study supports recommendation from other studies to initiate chemical VTE prophylaxis after TSI as early as 24h post injury.

Abstract
Aim
This study examines the safety and timing initiating VTE prophylaxis post traumatic splenic injuries (TSI).
Method
Patients with TSI were identified from prospectively maintained Trauma Audit and Research Network (TARN) database from 2015–2020 in a single tertiary trauma centre. Clinical and radio-logical information were collected retrospectively. TSI were graded using American Association for the Surgery of Trauma (AAST) splenic injury scale. Chemical venous thromboprophylaxis initiation were categorised as not given, <48h and >48h following the injury.
Results
In total 102 patient were included out of 136 patients identified with TSI. 34 patients were excluded for lack of electronic data, palliative decision, or fatal condition on arrival. 12 patients out of 102 required operative management (OM) and 90 patients NOM. VTE prophylaxis was not given for 31 (30.4%). Medical reasons for this include severe brain injury and early discharge before 48 hours. VTE prophylaxis was initiated for 37 (36.3%) patients within 48 hours, and for 34 patients (33.3%) after 48 hours of admission. Seven patients developed thromboembolic events, majority of which (6/7) received VTE prophylaxis after 48 hours. Importantly, none of the patients who received VTE prophylaxis had rebleeding.

Abstract
Abstract
Aim
Pedicle screws provide excellent fixation for a wide range of indications; their adoption in the cervical spine has been slower than in the thoracic and lumbar spine, largely due to the smaller pedicle sizes and proximity to neurovascular structures in the neck. Recent years have seen the development of technology to improve accuracy and thereby safety in cervical pedicle screw placement over traditional fluoroscopic techniques, including intraoperative 3D navigation, computer assisted systems and physical templates with screw guides. We have performed a systematic review into the accuracy rates of the various systems.
Method
PubMed and Cochrane Library databases were searched; keywords "pedicle screw cervical spine" were searched; 9 valid papers involving 1427 screws were found.
Results
Accuracy rates were 80.6% for fluoroscopy, 91.4% for navigation methods, and 96.7% for templates.
Conclusions
Superior results for templates are complemented by reduced radiation exposure to patient and surgeon; however, the technology requires prolonged pre-operative planning to create the bespoke template, and the development of an infrastructure to allow for their rapid production and delivery is needed before they become more widely available.
Two broad methods of navigation currently exist: intraoperative CT scanning providing real-time 3D navigation and preoperative CT registration in relation to a fixed reference with intraoperative computer assistance. At present, these methods are more commonly used, due to their proven improved accuracy rates over fluoroscopy, availability in emergencies and alongside minimally invasive techniques.
Despite their novelty and limitations, templates provide promising accuracy scores, although practical considerations may inhibit their proliferation.

Abstract
The aim of this study was to produce high yield of a local bacterial alkaline protease in the yeast system because the scientific involvement of microorganisms in enzyme production is still not given enough attention in Saudi Arabia. Soil samples were collected from the rhizosphere of some desert plants in Saudi Arabia. Ninety-three alkaline protease producing bacterial isolates were recovered on skimmed-milk agar at pH 9.4 and 45°C for 48 hr. Isolate D9 obtained from the rhizosphere of Heliotropium digynum at Dhahran City was the most potent isolate in respect to enzyme productivity (184.6 U/ml). The full gene of alkaline protease was amplified and showed the expected size (1300 bp). Restriction enzymes analysis also verified the integrity of the PCR product. The sequence of the protease gene revealed an open reading frame of 1329 nt correspond to the full length of the protease gene of isolate D9 encoding a 443 aa protein. After ligation of the amplified gene by the TA cloning method, digestion with appropriate restriction enzymes confirmed the integrity of the cloned gene. The insert was prepared by two PCRs that were conducted with a pair of primers specifically designed for this purpose. The digested and purified cloning vector pRS426/GAL1p-207-Glu-MS was ligated with the insert then transformed into various strains of Saccharomyces cerevisiae via the electroporation method. Maximum protease expression was done by recombinant OS303 in galactose containing media (145.5 U/ml) with an approximately 2-fold increase when compared with the wild OS303 strain., this may be due to ability to activate gal operon.

Abstract
Abstract
Aim
Gallstone related disease accounts for a third of the admissions to the Surgical Department. In June 2019, a clinical audit was undertaken at Great Western Hospital assessing the number of patients who underwent cholecystectomy, following initial diagnosis, in accordance to current guidelines. The results demonstrated a very low number of patients had cholecystectomy, within the targeted time frame, which led to the implementation of a dedicated operative “hot gallbladder” list weekly. In June 2020, we re-audit the service to evaluate the impact of the change implemented.
Method
A retrospective observational analysis of patients admitted to the Hospital in June 2020 with gallstone related disease. Data was collected using the Surgical on-call lists, these were analysed and patients selected according to the reason for admission, only gallstone related issues were considered in this analysis. Finally, via Medway, the time from admission to surgery was assessed.
Results
Despite the disruption in service provision due to COVID-19, the implementation of the “hot gallbladder” list led to a 10.7% increase in timely cholecystectomies, bringing the overall compliance to 14%. There was also a significant reduction in biliary relate re-admissions, from 58% to 37%. Despite 47.3% of patients were still awaiting surgery, the waiting list was reduced by 5.2% in only 1 year.
Conclusions
This study demonstrated that the implementation of the “hot gallbladder” list has improved the compliance with the current guidelines. The change has brought us in line with the national average of 15%, as estimated by RCSEng, therefore demonstrating the efficacy of the weekly list.

Abstract
BACKGROUND Levetiracetam is a relatively new-generation antiseizure drug approved for the treatment of focal and generalized seizures. Despite its favorable side effect profile and minimal drug-drug interactions, neuropsychiatric side effects are reported in up to 13% of children. A few case series have suggested that supplementation of pyridoxine may mitigate these side effects, but controlled trials are lacking. To address this issue, a randomized interventional study was carried out in a pediatric tertiary hospital to qualify and quantify the potential beneficial effect of pyridoxine in attenuating the neuropsychiatric side effects of levetiracetam in children. METHODS A total of 105 children with epilepsy who were taking levetiracetam (as a monotherapy or an adjunct) who showed behavioral symptoms coinciding with the start of levetiracetam, were included. Patients randomly and blindly received either a therapeutic (pyridoxine group, 46 of 105, 44%) or a homeopathic dose of pyridoxine (placebo, 59 of 105, 56%). A 30-item behavioral checklist was used to qualify and quantify the behavioral side effects at baseline and at different time points following initiation of treatment. RESULTS Both placebo and pyridoxine groups experienced a statistical reduction in behavioral scores when compared with baseline. Our study indicated that although there was a placebo effect, the improvement in neuropsychiatric symptoms was more prominent in children who received therapeutic doses of pyridoxine. CONCLUSIONS These data provide clinicians with pertinent evidence-based information that suggests that a trial of pyridoxine in patients who experience behavioral side effects due to the use of levetiracetam may avoid unnecessary change of antiseizure medications.

Abstract
OBJECTIVE This study evaluated the efficacy of the soluble epoxide hydrolase (sEH) inhibitor, TPPU on chronic NG-Nitro L-arginine methyl ester (L-NAME)-induced hypertension in rats and its effects on plasma Angiotensin II (Ang II), cardiac Angiotensin-converting enzyme (ACE) and Angiotensin II receptor type 1 (AT1R) expressions. MATERIALS AND METHODS Forty Sprague Dawley rats were divided into 5 groups. Two groups served as control and received orally either vehicle or TPPU (3 mg/kg) for five weeks. The other three groups were given L-NAME (50 mg/kg/day) in drinking water for five weeks. Two weeks after the L-NAME treatment, animals received orally either saline or TPPU (3 mg/kg/day) or lisinopril (10 mg/kg/day) daily for 3 weeks. Blood pressure (BP) was measured weekly. At the end of the experiment, plasma Ang II, cardiac ACE and AT1R protein and gene expressions were determined. RESULTS L-NAME caused a significant increase in BP of the animals. TPPU and lisinopril resulted in normalization of L-NAME-induced hypertension. They also caused a significant reduction in Ang II and ACE protein and gene expressions compared to L-NAME and vehicle-treated animals. CONCLUSIONS This study demonstrates that TPPU effectively lowers L-NAME-induced hypertension in rats. The mechanism of its antihypertensive effect is likely mediated by the suppression of ACE gene and protein expression, leading to a lower Ang II level.

Abstract
Abstract
Background
Cardiac nerves regulate many important physiological functions of the heart such as heart rate and contractility. The emerging role of cardiac nerves during tissue homeostasis and regeneration is beginning to be appreciated. We discovered that neonatal mice are capable of regenerating their hearts following injury within a brief period after birth by proliferation of the pre-existing cardiomyocytes. Furthermore, we have demonstrated that cholinergic nerves play an important role in guiding the neonatal heart regenerative response. However, the adult mammalian heart, including the human heart, is incapable of regeneration following injury. Thus, there is great excitement about understanding the evolutionarily conserved mechanisms of endogenous cardiac regeneration, so that we can explore potential avenues to reawaken this process in adult humans.
Purpose
Our overarching goal is to define the mechanisms by which cholinergic nerves regulate heart regeneration following ischemic injury by using the neonatal mouse heart regeneration model. These studies will uncover novel pathways by which cholinergic signaling promotes cardiomyocyte proliferation and heart regeneration, which holds significant therapeutic potential for treatment of adult heart disease.
Methods
In this project, we employed genetically engineered mouse models of the critical receptors for cholinergic signaling in the heart to define the mechanisms of cholinergic nerve regulation of heart regeneration. First, we generated a cardiomyocyte-specific deletion of the muscarinic receptor (M2), the most predominant muscarinic receptor subtype present in the heart. In addition, we utilized the α7 nicotinic receptor (Chrna7) knockout mice to study the role of Chrna7 in endogenous immune cells, which is the main mediator of the cholinergic anti-inflammatory pathway. These mouse models will address how cholinergic nerves regulate heart regeneration via the M2 muscarinic receptor signaling and the inflammatory response following injury.
Results
Our results demonstrate that inhibition of two different cholinergic receptors (muscarinic and nicotinic) results in a reduction in cardiomyocyte proliferation and inhibition of the neonatal cardiac regenerative response following injury. More importantly, we demonstrate that cholinergic signaling mediates the cardiac regenerative response mainly through suppression of pro-inflammatory cytokines via the cholinergic anti-inflammatory pathway.
Conclusions
Cholinergic nerve signaling plays an important role in mounting a robust cardiac regenerative response following injury. These results have significant therapeutic potential, which will forge new paradigms with respect to the role of cardiac nerves during mammalian cardiac regeneration and reveal potential mechanisms regarding the benefits of nerve stimulation following cardiac injury in humans.

Abstract
An increasing number of mitochondrial diseases are found to be caused by pathogenic variants in nuclear encoded mitochondrial aminoacyl-tRNA synthetases. FARS2 encodes mitochondrial phenylalanyl-tRNA synthetase (mtPheRS) which transfers phenylalanine to its cognate tRNA in mitochondria. Since the first case was reported in 2012, a total of 21 subjects with FARS2 deficiency have been reported to date with a spectrum of disease severity that falls between two phenotypes; early onset epileptic encephalopathy and a less severe phenotype characterized by spastic paraplegia. In this report, we present an additional 15 individuals from 12 families who are mostly Arabs homozygous for the pathogenic variant Y144C, which is associated with the more severe early onset phenotype. The total number of unique pathogenic FARS2 variants known to date is 21 including three different partial gene deletions reported in four individuals. Except for the large deletions, all variants but two (one in-frame deletion of one amino acid and one splice-site variant) are missense. All large deletions and the single splice-site variant are in trans with a missense variant. This suggests that complete loss of function may be incompatible with life. In this report, we also review structural, functional, and evolutionary significance of select FARS2 pathogenic variants reported here.

Abstract
OBJECTIVE The current study aims to compare the rate of intraoperative nausea and vomiting after repeat cesarean delivery (CD) under two different approaches: by intraperitoneal incision repair or by uterus exteriorization for incision reapair. MATERIALS AND METHODS We conducted a single-blinded randomized clinical trial (NCT03009994) at a tertiary University Hospital between the 1st of September 2016 and the 31st of December 2017. The study included pregnant women at term of gestation (>37 weeks) scheduled for repeat CD under spinal anesthesia. Women were assigned to either uterine exteriorization for incision repair (Group I) or intraperitoneal incision repair (Group II). The primary assessed was the rate of nausea and vomiting during CD. RESULTS The study included 1028 women in the final analysis. The rate of intraoperative nausea and vomiting was significantly lower in the intraperitoneal repair group compared to the exteriorization group (24% versus 38.7%, p= 0.001). Likewise, occurrence of uterine atony and the need for additional uterotonics were significantly lower in the intraperitoneal repair group (p= 0.001 and 0.02 respectively). Postoperatively, the rate of nausea and vomiting (12.6 % versus 21 %; P=0.001), and the time to the first recognized bowel movement (12.3 hours versus 14.1 hours; P=0.003) were significantly lower in the intraperitoneal repair group compared to the exteriorization group. CONCLUSIONS Intraperitoneal repair of the uterine incision during repeat CD is beneficial compared to exteriorization. Improvements in the rate of intra- and postoperative nausea, vomiting, uterine atony and time to the first recognized bowel movement were observed in patients operated with this technique.

Abstract
The World Bank is publishing nine volumes of Disease Control Priorities, 3rd edition (DCP3) between 2015 and 2018. Volume 9, Improving Health and Reducing Poverty, summarises the main messages from all the volumes and contains cross-cutting analyses. This Review draws on all nine volumes to convey conclusions. The analysis in DCP3 is built around 21 essential packages that were developed in the nine volumes. Each essential package addresses the concerns of a major professional community (eg, child health or surgery) and contains a mix of intersectoral policies and health-sector interventions. 71 intersectoral prevention policies were identified in total, 29 of which are priorities for early introduction. Interventions within the health sector were grouped onto five platforms (population based, community level, health centre, first-level hospital, and referral hospital). DCP3 defines a model concept of essential universal health coverage (EUHC) with 218 interventions that provides a starting point for country-specific analysis of priorities. Assuming steady-state implementation by 2030, EUHC in lower-middle-income countries would reduce premature deaths by an estimated 4·2 million per year. Estimated total costs prove substantial: about 9·1% of (current) gross national income (GNI) in low-income countries and 5·2% of GNI in lower-middle-income countries. Financing provision of continuing intervention against chronic conditions accounts for about half of estimated incremental costs. For lower-middle-income countries, the mortality reduction from implementing the EUHC can only reach about half the mortality reduction in non-communicable diseases called for by the Sustainable Development Goals. Full achievement will require increased investment or sustained intersectoral action, and actions by finance ministries to tax smoking and polluting emissions and to reduce or eliminate (often large) subsidies on fossil fuels appear of central importance. DCP3 is intended to be a model starting point for analyses at the country level, but country-specific cost structures, epidemiological needs, and national priorities will generally lead to definitions of EUHC that differ from country to country and from the model in this Review. DCP3 is particularly relevant as achievement of EUHC relies increasingly on greater domestic finance, with global developmental assistance in health focusing more on global public goods. In addition to assessing effects on mortality, DCP3 looked at outcomes of EUHC not encompassed by the disability-adjusted life-year metric and related cost-effectiveness analyses. The other objectives included financial protection (potentially better provided upstream by keeping people out of the hospital rather than downstream by paying their hospital bills for them), stillbirths averted, palliative care, contraception, and child physical and intellectual growth. The first 1000 days after conception are highly important for child development, but the next 7000 days are likewise important and often neglected.

Abstract
Intellectual disability (ID) is a measurable phenotypic consequence of genetic and environmental factors. In this study, we prospectively assessed the diagnostic yield of genomic tools (molecular karyotyping, multi-gene panel and exome sequencing) in a cohort of 337 ID subjects as a first-tier test and compared it with a standard clinical evaluation performed in parallel. Standard clinical evaluation suggested a diagnosis in 16% of cases (54/337) but only 70% of these (38/54) were subsequently confirmed. On the other hand, the genomic approach revealed a likely diagnosis in 58% (n=196). These included copy number variants in 14% (n=54, 15% are novel), and point mutations revealed by multi-gene panel and exome sequencing in the remaining 43% (1% were found to have Fragile-X). The identified point mutations were mostly recessive (n=117, 81%), consistent with the high consanguinity of the study cohort, but also X-linked (n=8, 6%) and de novo dominant (n=19, 13%). When applied directly on all cases with negative molecular karyotyping, the diagnostic yield of exome sequencing was 60% (77/129). Exome sequencing also identified likely pathogenic variants in three novel candidate genes (DENND5A, NEMF and DNHD1) each of which harbored independent homozygous mutations in patients with overlapping phenotypes. In addition, exome sequencing revealed de novo and recessive variants in 32 genes (MAMDC2, TUBAL3, CPNE6, KLHL24, USP2, PIP5K1A, UBE4A, TP53TG5, ATOH1, C16ORF90, SLC39A14, TRERF1, RGL1, CDH11, SYDE2, HIRA, FEZF2, PROCA1, PIANP, PLK2, QRFPR, AP3B2, NUDT2, UFC1, BTN3A2, TADA1, ARFGEF3, FAM160B1, ZMYM5, SLC45A1, ARHGAP33 and CAPS2), which we highlight as potential candidates on the basis of several lines of evidence, and one of these genes (SLC39A14) was biallelically inactivated in a potentially treatable form of hypermanganesemia and neurodegeneration. Finally, likely causal variants in previously published candidate genes were identified (ASTN1, HELZ, THOC6, WDR45B, ADRA2B and CLIP1), thus supporting their involvement in ID pathogenesis. Our results expand the morbid genome of ID and support the adoption of genomics as a first-tier test for individuals with ID.

Abstract
With vaccination efforts forced to compete for scarce resources at a time when national health budgets, global health resources, and the global donor community are facing considerable strains, advocates of vaccines have sought to better identify, measure, and articulate the value of vaccination. Critics of current analyses of the value of vaccination argue that a broader view is required, one that includes the additional economic benefits of vaccines or acknowledges the social and ethical aims advanced by vaccination programs. Much of this work has paid inadequate attention to the need to apply any expanded view of value consistently across medical interventions, to the close and complex integration of vaccination efforts with other health initiatives, and to the fact that subjectivity and judgments are present in quantitative and qualitative evidence alike. To fully realize the value of vaccination, far more attention, investment, and research are required to better understand the deliberations and decision-making processes by which any kind of evidence is translated into policy.

Abstract
Historical evidence demonstrates the validity of the concept "Grand Convergence". The Lancet commission identified the major challenges facing low and lower middle income countries including the unfinished agenda, non-communicable diseases and injuries and an approach to funding and achieving these objectives along with progress towards universal health care. The role of vaccines is summarized as a major approach to accomplish a Grand Convergence in a generation.

Abstract
Inherited aberrancies in intracellular vesicular transport are associated with a variety of neurological and non-neurological diseases. RUSC2 is a gene found on chromosome 9p13.3 that codes for iporin, a ubiquitous protein with high expression in the brain that interacts with Rab proteins (GTPases implicated in intracellular protein trafficking). Although mutations in Rab proteins have been described as causing brain abnormalities and intellectual disability, until now no disease-causing mutations in RUSC2 have ever been reported in humans. We describe, to our knowledge for the first time, three patients with inherited homozygous nonsense mutations identified in RUSC2 on whole-exome sequencing. All three patients had central hypotonia, microcephaly, and moderate to severe intellectual disability. Two patients had additional features of early-onset epilepsy and absence of the splenium. This report adds to the ever-expanding landscape of genetic causes of intellectual disability and increases our understanding of the cellular processes underlying this important neurological entity.
