The Impact

Covid 19 is an infectious disease caused by coronavirus. This virus first appeared in Wuhan China. The manifestations of this disease vary in each person, ranging from no symptoms, mild symptoms to severe symptoms that can even cause death. Mothers who are confirmed to have Covid 19 can experience various symptoms such as those who are not pregnant. This research method is a descriptive study to describe the condition of pregnancy with the COVID 19 virus infection which is taken from various previous research sources. Result: Symptoms that appear include cough, fever and sore throat. However, in pregnant women, the placenta serves as a barrier that can prevent transmission of Covid 19 from mother to fetus. Pregnant women with comorbidities who are confirmed positive for Covid 19 increase the risk of illness and increase the need for ICU. The diagnosis of Covid 19 can be confirmed in various ways, but the gold standard that can be used as a reference for diagnosing Covid 19 is the polymerase chain reaction (PCR) culture test. The impact of pregnancy confirmed by Covid 19 is maternal mortality, preterm delivery and fetal growth disorders and fetal death.

The Impact

The impact of human papillomavirus (HPV) infection on pregnancy is a major problem of medicine. The transmission of the virus from mother to fetus is a process yet unresolved. The immune response and changed hormonal status of pregnant women might facilitate infection. A research on the prevalence of HPV infection was conducted at the Clinic of Obstetrics, Medical University of Lublin (Poland). The studied group included 152 randomly selected women. The material was tested for the presence of HPV DNA by means of polymerase chain reaction (PCR). The aim of the research was to assess the relation between HPV infections detected in the buccal smears of the neonates and the incidence of such infections in the cervical/buccal smears of their mothers. In the group of 152 infants HPV was found in 16 (10.53%). Among the cervical/buccal smears, HPV was isolated, respectively, in 24 (15.79%) and in 19 (12.5%) pregnant women. Statistically significant differences in the prevalence of HPV swabs from the newborns and the cervical/buccal smears of their mothers were found (p< 0.001). The identification of mothers in whose buccal smears HPV was detected can help develop a group of children who run a relatively significant risk of being infected.

This report describes four suspected rabies cases in domestic dogs that were involved inhuman exposures. In all these cases, the animals were buried for substantial times beforerabies testing was performed. Animal rabies is endemic in South Africa and domestic dogsare the main vector for transmission to humans. Diagnosis of rabies in humans is complicated,and diagnosis in the animal vector can provide circumstantial evidence to support clinicaldiagnosis of rabies in humans. The gold standard diagnostic method, fluorescent antibodytest (FAT), only delivers reliable results when performed on fresh brain material and thereforedecomposed samples are rarely submitted for diagnostic testing. Severely decomposed brainmaterial was tested for the presence of rabies virus genomic material using a quantitativereal-time reverse transcription polymerase chain reaction (q-real-time RT-PCR) assaywhen conventional molecular methods were unsuccessful. This may be a useful tool in theinvestigation of cases where the opportunity to sample the suspected animals post mortem wasforfeited and which would not be possible with conventional testing methodologies becauseof the decomposition of the material.

Although the Giemsa-stained thick blood smear (GTS) remains the gold standard for the diagnosis of malaria, molecular methods are more sensitive and specific to detect parasites and can be used at reference centers to evaluate the performance of microscopy. The description of the Plasmodium falciparum, P. vivax, P. malariae and P. ovale ssrRNA gene sequences allowed the development of a polymerase chain reaction (PCR) that had been used to differentiate the four species. The objective of this study was to determine Plasmodium species through PCR in 190 positive smears from patients in order to verify the quality of diagnosis at SUCEN's Malaria Laboratory. Considering only the 131 positive results in both techniques, GTS detected 4.6% of mixed and 3.1% of P. malariae infections whereas PCR identified 19.1% and 13.8%, respectively.

Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose To evaluate potential differences in days on mechanical ventilation for patients with coronavirus disease 2019 (COVID-19) based on route of administration of analgesic and sedative medications: intravenous (IV) alone vs IV + enteral (EN). Summary This institutional review board–approved study evaluated ventilation time and fentanyl or midazolam requirements with or without concurrent EN hydromorphone and lorazepam. Patients were included in the study if they were 18 to 89 years old and were admitted to the intensive care unit with a positive severe acute respiratory syndrome coronavirus 2 reverse transcription and polymerase chain reaction or antigen test and respiratory failure requiring invasive mechanical ventilation for more than 72 hours. In total, 100 patients were evaluated, 60 in the IV-only group and 40 in the IV + EN group. There was not a significant difference in ventilation time between the groups (mean [SD], 19.6 [12.8] days for IV + EN vs 15.6 [11.2] days for IV only; P = 0.104). However, fentanyl (2,064 [847] μg vs 2,443 [779] μg; P &lt; 0.001) and midazolam (137 [72] mg vs 158 [70] mg; P = 0.004) requirements on day 3 were significantly higher in the IV-only group, and the increase in fentanyl requirements from day 1 to day 3 was greater in the IV-only group than in the IV + EN group (378 [625] μg vs 34 [971] μg; P = 0.033). Conclusion Addition of EN analgesic and sedative medications to those administered by the IV route did not change the duration of mechanical ventilation in patients with COVID-19, but the combination may reduce IV opioid requirements, decreasing the impact of IV medication shortages.

Clinical Awareness

The incidence of community-acquired respiratory viruses (CARVs) is ∼15 cases per 100 patient-years after lung transplantation (LTx). Paramyxoviruses account for almost 50% of the cases of CARV infection in LTx. Most patients will be symptomatic with a mean decline of 15 to 20% in forced expiratory volume in 1 second. The attributable death rate is low in recent years 15 to 25% CARV infected LTx patients will develop chronic lung allograft dysfunction within a year after CARV infection. This risk seems to be increased in comparison to the noninfected LTx recipient.Detection rate of CARV dependent on clinical awareness, sampling, and diagnostic method with nucleic acid testing by polymerase chain reaction in bronchoalveolar lavage is the gold standard after LTx.There is no approved treatment for paramyxoviruses, most centers use ribavirin by various routes. Toxicity of systemic ribavirin is of concern and some patients will have contraindication to this treatment modality. Treatment may reduce the risk to develop chronic lung allograft dysfunction and respiratory failure. Agents under development are inhibiting viral attachment and use silencing mechanisms of viral replication.

Aspergillosis refers to fungi infections of the respiratory tract caused by Aspergillus species, especially Aspergillus fumigatus. Infection of A. fumigatus was increased in the last few years due to either resistances to antibiotics or the influence of other factors such as other fungal infections. The present study aimed to review the impact of Aspergillus fumigatus in Aspergillosis cases, and study the role of Singleplex PCR for amplification of ITS1, ITS4 of rRNA gene in the detection of fungal isolate. In this study, One hundred sputum samples were collected from patients admitted to the specialize chest and respiratory diseases center / Baghdad who were suffering from respiratory problems. During these studied, molds were isolation and identification based on Conventional method (Direct microscopy by using 10% KOH, and fungal culture was done on Sabouraud Dextrose agar supplemented with chloramphenicol and on Czapek-Dox agar incubated at 37°C and examined for 3-7 days then macroscopic, microscopic examination of the colony by(lactophenol cotton blue stain )and molecular methods by using Polymerase chain reaction (PCR)technique for identification. The 10% KOH examination was positive for 35 cases, while laboratory culturing was positive for 53 cases. Aspergillus sp were isolated from 44(83%) patients; A. fumigatus was isolated in 23 (42. 4%) patients while A. flavus, A. niger, and A. terreus were isolated from 11 (20. 08%), (13. 2%) and 3 (5. 7%) patients respectively, also isolated Penicillium spp. at percentage 1(1. 9%). In this study. The ages of participants ranged from 10-70years with a mean age of 34years, the males were more susceptible to fungal infection, were recorded 35/53 (66. 3), compared to females were 18/53 (33. 96). The infection of fungi was more prevalent in ages 30-40recorded 26(53. 06%) followed by ages 40-50, 13(26. 5), while the lowest infection recorded in the age group 10- 20 years was 2(2. 04%). DNA isolated from twenty-three A. fumigatus isolates was used as a template, and the specific of oligonucleotide primer sequences were used in conventional PCR to detect the presence of internal transcribed spacer region ( ITS) region of the rRNA gene for Aspergillus fumigates. The results of the PCR amplification of the rRNA gene showed that this gene was present in 19 samples out 23 positive samples which isolation with a PCR product size of approximated 385 bp, while 4 samples out 23 positive samples showed negative results for the presence of this gene as indicated by the absence of the PCR products in their relevant lanes. Statistical analysis revealed that the PCR to have a sensitivity of 95. 1% in the detection of Aspergillus fumigatus in Aspergillosis cases. Polymerase chain reaction (PCR) is a rapid, specific, and sensitive method to detect Aspergillus fumigatus in aspergillosis cases of humans.

Abstract Background Hypospadias, the most frequent congenital male external genitalia abnormality, is usually associated with curvature of the ventral penis, i.e. chordee. Abnormality of darto tissue has been suggested as the pathophysiology of chordees. Collagen is one of the most abundant fibrous proteins within the extracellular matrix. In this study, we determined the expression of collagen 1 (COL1A1) and COL6A1 in patients with hypospadias and associated them with the severity of penile curvature. Methods We included 60 children < 18 years old, consisting of 20 distal hypospadias, 20 proximal hypospadias patients, and 20 controls in our institution from 2017 – 2020. The expression of COL1A1 and COL6A1 in darto tissue was determined by reverse-transcriptase polymerase chain reaction (qPCR). The penile curvature severity was classified as mild (< 30 degrees), moderate (30–60 degrees), and severe (> 60 degrees). Results qPCR showed that COL1A1 and COL6A1 expression was significantly downregulated in the distal (0.88 (0.38–2.53) and 0.54 (0.16–4.35), respectively) and proximal 0.76 (0.33–2.57) and 0.57 (0.18–1.38), respectively) hypospadias groups compared to controls (1.85 (0.24–4.61) and 0.93 (0.17–4.06), respectively) with p-values of 0.024 and 0.018, respectively. Furthermore, there was a moderate correlation between COL1A1 and COL6A1 expression (r = 0.458, p < 0.0001). Interestingly, COL1A1 and COL6A1 were also significantly downregulated in the moderate and severe chordee groups compared to the mild chordee groups, with p-values of 0.003 and 0.037, respectively. Conclusions Aberrant COL1A1 and COL6A1 expression might affect abnormalities in darto tissue and penile curvature severity in hypospadias patients.
