Tissue injury initiates a cascade of peripheral neuronal responses. Noxious stimuli are transduced to electrical activity at the peripheral terminals of Aδ and C polymodal fibers and are immediately conducted to the dorsal horn of the spinal cord. The cellular and blood vessel damage from the injury along with inflammatory and tumor cells, release biochemical mediators (bradykinin, calcium and potassium ions, substance P, and prostaglandins) that activate or sensitize Aδ and C polymodal afferent nociceptors that transmit pain impulses to the spinal cord and stimulate local inflammatory flare and wheal responses. Concurrently, substance P and prostaglandins increase the local tissue inflammation creating local primary hyperalgesia.[123] With repeated tissue damage, such as repeated heel lance, the associated inflammation and tenderness may extend into adjacent uninjured tissue giving rise to allodynia[121] and a 50% lower cutaneous flexor reflex threshold compared with the intact contralateral heel.[57]
These local spinal cord responses have a profound effect on a neonate's biobehavioral response to stimulation. Compared with full-term infants, children, adolescence, and adults, preterm infants have a lower threshold and a more pronounced reflex response to touch.[46] The decreased pain threshold makes the infant more sensitive to noxious stimuli such that touch stimulation near the injured area causes intense pain for days or weeks.[56] With repeated exposure to noxious stimuli or touch, the lowered threshold declines even further due to the influence of NMDA and GABA on the excitability of the sensory neurons of the spinal cord. The significant variability in pain response observed in neonates is due to the continually decreasing touch threshold, the increasing neuronal sensitization and the preceding painful/stressful interventions in the last hour,[81] 24 h,[71] or cumulatively since birth.[70,87] The clinical implication for tiny neonates is that compared with adults, the behavioral response to routine care will be the same as the behavioral response to an invasive procedure. In addition, a diaper change can elicit pain-like behaviors and physiologic responses if preceded by a heel lance 30 min before.[82] Depending on the gestational age of the infant, the number of prior painful experience, the infant's behavioral state, or acuity of illness, a single stimulus may elicit a pain response that lasts several minutes or cause no reaction at all.[48,53,114]

Since the emergence of SARS-CoV-2, evolutionary pressure has driven large increases in the transmissibility of the virus. However, with increasing levels of immunity through vaccination and natural infection the evolutionary pressure will switch towards immune escape. Genomic surveillance in regions of high immunity is crucial in detecting emerging variants that can more successfully navigate the immune landscape.
As SARS-CoV-2 moves towards endemicity and new variants emerge, genomic data obtained from random community samples can augment routine surveillance data without the potential biases introduced due to higher sampling rates of symptomatic individuals.
Since July 2021 the lineage AY.4.2 (Pango nomenclature [9]), a descendant of the original Delta variant (henceforth B.1.617.2) has increased in proportion in routine surveillance data for England from 8.5% the week beginning 4 October [10] to 14.7% the week beginning 31 October [11]. AY.4.2 was declared a variant under investigation (VUI) by the UK Health Security Agency on 20 October 2021 [12]. Globally AY.4.2 had been detected in 43 countries by 22 November 2021 [13] but had only been estimated at a cumulative proportion greater than 1% in Poland [14]. AY.4.2 has two defining mutations in the spike protein, Y145H and A222V, but is otherwise similar to AY.4, a lineage that is far more widespread. AY.4 was the most prevalent lineage in England on 29 October 2021 [11] and had been detected in 87 countries by 22 November 2021 [15], in some of which it had already been reported as the most prevalent lineage (by 23 November 2021) [16, 17].
England has recorded high levels of SARS-CoV-2 infection over the course of the pandemic [4, 18] and vaccinated, as part of its mass vaccination campaign (Pfizer/BioNTec, Oxford/AstraZeneca and Moderna), a large proportion of its population (80.3% of over 12 year olds double vaccinated by 27 November 2021), with further booster jabs (Pfizer/BioNTec or Moderna) being rolled out in adults (30.5% of over 12 year olds having received a booster dose by 27 November 2021) [18]. This has led to high levels of antibodies against coronavirus with 92.8% of adults in England estimated to test positive for antibodies (IgG antibodies against the SARS-CoV-2 trimeric spike protein) in the week beginning 1 November 2021 [19]. With high vaccination coverage in the population it is likely that there is substantial selective pressure on SARS-CoV-2 towards immune escape and vaccine breakthrough infections. Genomic surveillance in highly immunised regions is crucial to detect emerging variants that can more successfully navigate the immune landscape that has been created by both natural infection and vaccination.
The proportion of AY.4.2 was found to be increasing between 9 September and 5 November 2021, as also reported in the routine data surveillance for England [11]. In round 15, AY.4.2 represented 11.8% of infections in line with other estimates [11]. This increase in proportion corresponded to a 15% increase in transmission advantage although this assumes the generation time distribution has remained constant; a decrease of the generation time distribution for AY.4.2 would also explain the increased growth but we are unable to test for this with prevalence data. In the past, the A222V mutation, associated with AY.4.2, increased in frequency but this was eventually deemed to be due to a founder effect and not a transmission advantage [40, 41]. Given the high levels of geographic dispersion (though with some clustering) during rounds 14 and 15 it is highly unlikely that a founder effect can explain the current growth, though we can not rule out a similar effect due to higher proportions of AY.4.2 in school-aged children (prevalence increased to a greater extent in school-aged children than in adults from July to September 2021 [4, 42]). However, as the proportion AY.4.2 was approximately constant by age in round 15 this growth advantage would not be detected into the future if this was the case.
Though we have focused on AY.4.2 we have detected a diverse set of Delta sub-lineages, with even a single detection corresponding to approximately 1000 swab-positive infections in the community at one time during the study period. The short time over which AY.4.2 went from being an undeclared lineage to a variant under investigation shows how crucial it is to have careful surveillance of all lineages irrespective of frequency. For 38 of the 44 detected lineages, it was unable to be determined whether the proportion was increasing or decreasing.
Since the beginning of the pandemic, selective pressure has led to rapid evolution in the spike protein [50] driving leaps in transmissibility [5]. However, as a greater proportion of the population acquires immunity through either infection or vaccination there will be a shift in evolutionary pressure towards immune escape. Even in England where there are high levels of vaccination and past infection, new variants such as AY.4.2 have emerged with advantages over previous strains. With the continued emergence of variants able to evade population immunity and undergoing transmission, SARS-CoV-2 is highly unlikely to ever undergo local extinction and is likely moving towards a state of endemicity. At the point of endemicity it is probable that adaptive evolution would more closely resemble the continual antigenic drift observed in influenza H3N2 [51, 52]. As the evolutionary phase of SARS-CoV-2 progresses towards endemicity, continued surveillance is paramount in not only detecting increased levels of transmissibility for specific lineages, but in also better characterising the mechanism behind such changes and informing policy around testing (including case definitions). Representative community studies such as REACT-1 can be useful in measuring the relative growth of lineages and in characterising differences in viral loads, symptomatology and geographic distribution.
Few Christian leaders since the Reformation have been as gifted as Jonathan Edwards. A man of intense personal devotion to Christ, he was a leader of revival, and a creative Reformed theologian as well as being a missionary and a philosopher fully meriting Hugh Martin's description of him as 'that greatest of metaphysical divines'. Yet it is likely that he would have preferred to be remembered simply as 'pastor of the Church of Northampton'. Preached in 1738 (the same year that Edwards published A Narrative of Surprising Conversions), Charity and Its Fruits gives us an insight into his regular pulpit ministry in the years between the Northampton revival of 1735 and 'the Great Awakening' of 1740. Entirely free from sentimentality this moving exposition of 1 Corinthians 13, like the better known Religious Affections, reveals Edwards' insistence both that true Christian experience is 'supernatural'- Spirit produced and Christ centered- and that 'all true Christian grace tends to practice'. These sermons show how it is possible to steer between Arminianism on the one hand and Antinomianism on the other. The concluding chapter on heaven as a world of love is perhaps the most beautiful in all Edwards's writings.
