Abstract
Streptococcus pneumoniae (SP) is an uncommon but potentially serious neonatal pathogen. SP is perceived as a significant cause of mortality and morbidity in infancy; however, there are relatively few cases of neonatal sepsis recorded, with an incidence between 1% and 11%. We aim to report the spectrum of morbidity associated with SP infections in the neonatal period. Two cases of neonatal SP infection are reported. The first neonate presented with a very early onset of severe clinical disease with bacteremia and pneumonia. She developed severe pulmonary hypertension and needed intensive ventilatory support, including nitric oxide, and vasoactive drugs. An SP serotype 23B was isolated from blood cultures and bronchial secretions as well as from the mother’s vaginal secretions. In the second case, the baby presented with bacteremia and meningitis. He remained hemodynamically stable and did not need respiratory support. Blood and cerebrospinal fluid cultures revealed an SP serotype 8. In both cases, the neonates were treated with vancomycin and cefotaxime. Both mothers remained well and asymptomatic during the perinatal period. These reported cases emphasize the importance of considering a wide range of microorganisms in the differential diagnosis of early-onset neonatal sepsis. Although uncommon, SP can have different clinical manifestations and cause significant diseases in newborns. Specific preventive measures against early-onset sepsis for this pathogen are yet to be implemented due to the absence of sufficient scientific evidence. For this reason, prompt and aggressive treatment remains the best therapeutic approach.

Abstract
BACKGROUND Invasive pneumococcal disease (IPD) in young infants is uncommon but associated with high morbidity and mortality. Accurate data on the burden of IPD in young infants in low-income countries are lacking. We examined the burden of IPD in infants <90 days old in Blantyre, Malawi over a 14-year period and evaluated the indirect impact of the 13-valent pneumococcal conjugate vaccine (PCV13) on vaccine-serotype IPD (VT-IPD) in this population. METHODS We conducted laboratory-based prospective IPD surveillance in infants <90 days of age admitted to Queen Elizabeth Central Hospital in Blantyre between 2005 and 2018, including 7 years pre-PCV13 and 7 years post-PCV13 introduction. IPD was defined as Streptococcus pneumoniae identified by culture from blood or cerebrospinal fluid. Serotypes were determined by multiplex polymerase chain reaction and latex agglutination testing. RESULTS We identified 130 cases of culture-confirmed IPD in infants <90 days old between 2005 and 2018. Total IPD incidence was declining before PCV13 introduction. The mean incidence of IPD was significantly lower in the post-PCV13 era. Serotypes 5 (27.8%) and 1 (15.6%) were most prevalent. Even after PCV13 introduction, VTs remained the primary cause of IPD, with serotype 5 accounting for 17.4% and serotype 1 for 13.0% of cases in young infants. CONCLUSION Vaccine serotypes 1 and 5 were the main cause of IPD in neonates and young infants, both before and after PCV13 introduction. This suggests incomplete indirect protection with persisting VT carriage across the population despite vaccination in this setting. Alternative vaccine schedules and other vaccine introduction approaches need to be considered to protect this vulnerable population.

Abstract
Systemic infections is one of the major causes of mortality worldwide, and a shortage of drug approaches applied for the rapid and necessary treatment contribute to increase the levels of death in affected patients. Several drug delivery systems based in nanotechnology such as metallic nanoparticles, liposomes, nanoemulsion, microemulsion, polymeric nanoparticles, solid lipid nanoparticles, dendrimers, hydrogels and liquid crystals can contribute in the biological performance of active substances for the treatment of microbial diseases triggered by fungi, bacteria, virus and parasites. In the presentation of these statements, this review article present and demonstrate the effectiveness of these drug delivery systems for the treatment of systemic diseases caused by several microorganisms, through a review of studies on scientific literature worldwide that contributes to better information for the most diverse professionals from the areas of health sciences. The studies demonstrated that the drug delivery systems described can contribute to the therapeutic scenario of these diseases, being classified as safe, active platforms and with therapeutic versatility.

Abstract
BACKGROUND Neonatal invasive pneumococcal disease (IPD) in developing countries is poorly described. We provide a baseline description of neonatal IPD in South Africa, before implementation of the 7-valent pneumococcal conjugate vaccine (PCV7) in 2009. METHODS Data from children (age ≤ 2 years) with IPD (pneumococcus identified from a normally sterile specimen) from January 2003 to December 2008 were extracted from a national laboratory-based surveillance database. Clinical and laboratory characteristics of IPD among neonates (0-27 days old) was compared with IPD among young children (≥ 28 days ≤ 2 years). Early-onset IPD (0-6 days old) was compared with late-onset IPD (≥ 7-27 days old). Isolates were serotyped using the Quellung reaction. RESULTS Overall 27,630 IPD cases were reported. Of the 26,277 (95%) with known ages, 6583 (25%) were ≤ 2 years of age, of which 4.5% (294/6583) were neonates. The estimated annual incidence of neonatal IPD in 2008 was 5 per 100,000 live births. Fifty-one percent of neonates with IPD presented with early-onset IPD. Case fatality ratios (CFRs) were high in both groups, 31% (28/89) in neonatal IPD versus 26% (614/2383) in non-neonatal IPD (P = 0.18). Among neonates, the meningitis cases (15/37, 41%) were associated with the highest CFR. The 13-valent pneumococcal conjugate vaccine (PCV13) serotypes accounted for 69% (134/194) of neonatal IPD isolates. CONCLUSIONS Pneumococcal neonatal disease in South Africa was not uncommon before PCV introduction and is associated with a high CFR. The indirect effect on neonatal IPD of PCV rollout requires further evaluation.

Abstract
Streptococcus pneumoniae is a rare cause of neonatal sepsis, and it is associated with significant morbidity and a very high fatality rate. The infection is usually acquired intrapartum, from the colonization of the maternal genital tract. Most affected neonates have an early-onset presentation of symptoms, usually within the first 48 hours after birth, which is similar to other causes of neonatal sepsis such as Streptococcus Agalactiae or Escherichia Coli. However, the virulence seems to be higher for Streptococcus pneumoniae, which has in addition a higher infant invasion/ maternal colonization ratio than Streptococcus Agalactiae. Pneumococcal vaccination has not resulted in a significant decline of neonatal cases. Many cases included ours, involved serotypes not present in the vaccine. Other strategies to protect these infants are necessary. We describe a late preterm infant with a fatal, early-onset sepsis caused by Streptococcus Pneumoniae serotype 28 A. Maternal vaginal culture grew the same bacteria.

Abstract
Vertically transmitted sepsis due to Streptococcus pneumoniae has a low incidence, and vaginal colonization among pregnant women is exceptional. Necrotizing pneumonia is uncommon in immunocompetent term neonates, and the prognosis is uncertain. At present, systematic screening does not seem warranted in pregnant women. Therefore, aggressive treatment of neonates remains the best treatment.

Abstract
Neonatal sepsis remains a feared cause of morbidity and mortality in the neonatal period. Maternal, neonatal, and environmental factors are associated with risk of infection, and a combination of prevention strategies, judicious neonatal evaluation, and early initiation of therapy are required to prevent adverse outcomes. This article reviews recent trends in epidemiology and provides an update on risk factors, diagnostic methods, and management of neonatal sepsis.
