This document summarizes research on modeling the spread of African swine fever (ASF) in Poland using multiplex network and machine learning approaches. Key findings include that blocking corridors on major highways could moderately delay the spread, while fencing the eastern border would have only a small effect on arrival time in swine districts. Machine learning combined with phenomenological models showed good predictive power. The research also found seasonal patterns and differences between border and interior regions, suggesting periodic importing of infections through Poland's eastern border may have occurred.

Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Per...Agriculture Journal IJOEAR
Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick's species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.

This document describes how spatial analysis was used to identify risk areas for Highly Pathogenic Avian Influenza (HPAI) in Europe and evaluate current health surveillance strategies. Logistic regression and co-kriging models were developed using data on HPAI cases, wetlands, poultry density, and temperature. Risk maps identified high-risk areas and hotspots. The models also showed that current surveillance sampling was not well matched to risk, missing some high-risk areas. Spatial analysis is a useful tool for targeting surveillance to areas most likely to benefit from control measures. This can help reduce health costs and improve prevention and control of animal diseases.

OS20 - Survey on 10years Foot and Mouth Disease outbreaks in Bushehr province...EuFMD
An epidemiological survey was conducted on foot and mouth disease (FMD) outbreaks in Bushehr Province, Iran from 2009 to 2019. The survey found 144 total outbreaks over the 10-year period, with 62% occurring when new FMD virus serotypes emerged in 2009 and 2015. Cattle feedlots and herds with free-range grazing cattle had the highest risk of disease. No significant correlation was found between FMD outbreaks and vaccination rates. The results indicate that FMD occurs at a hypoendemic level in Bushehr Province and that controlling disease in high-risk cattle populations like feedlots is a key factor for disease management.

The Rhipicephalus microplus tick is a major economic and veterinary concern on livestock production in tropical regions of the world. In Côte d’Ivoire, this invasive and proliferating tick has occupied almost the entire territory. To assess the prevalence of tick-borne haemoparasites in cattle following this invasion, a parasitological study was carried out in 179 farms in 54 departments. Blood and tick samples were collected from 895 cattle over one year of age, with 5 individuals per farm. Ten tick species were identified, of which Rhipicephalus microplus the most found. Microscopic analysis of blood smears identified 3 tick-borne haemoparasites: Anaplasma marginale, Anaplasma centrale and Babesia bovis, with prevalences between 4% and 24% according to departments. Only the Southern, Central, and Northern zones were infested with tick-borne haemoparasites of cattle. The highest prevalence of Babesia bovis (8%) was found in the Southern zone. Agboville’s department was the most infested by A. marginale (24%) and B. bovis (20%). Parasitological analyses revealed a low prevalence of tick-borne haemoparasites in Côte d’Ivoire. A molecular study should be conducted to confirm these results.

FLI Seminar on different response strategies: Stamping out or NeutralizationHarm Kiezebrink
During this spring, American poultry producers are losing birds by the millions, due to the High Pathogenic Avian Influenza outbreaks on factory farms. USDA APHIS applied the stamping out strategy in an attempt to prevent the flu from spreading.
With stamping out as the highest priority of the response strategy, large numbers of responders are involved. With in average almost 1 million caged layers per farm in Iowa, there is hardly any room for a proper bio security training for these responders. And existing culling techniques had insufficient capacity, the authorities had to decide to apply drastic techniques like macerating live birds in order to take away the source of virus reproduction.
This strategy didn't work; on the contrary. Instead of slowing down the spreading of the virus, the outbreaks continue to reoccur and have caused death and destruction in 15 USA states, killing almost 50 million birds on mote than 220infected commercial poultry farms, all within a very small time frame.
The question is whether the priority of the response strategy should be on neutralizing the transmission routes instead of on stamping out infections after they occur. All indicators currently point out into the direction that the industry should prioritize on environmental drivers: the connection between outbreaks and wild ducks; wind-mediated transmission; pre-contact probability; on-farm bio security; transmission via rodents etc.
Once the contribution of each transmission route has been determined, a revolutionary new response strategy can be developed based on the principle of neutralizing transmission routes. Neutralizing risks means that fully new techniques need to be developed, based on culling the animals without human – to – animal contact; integrating detergent application into the culling operations; combining culling & disposal into one activity.
This new response strategy will be the main subject of the FLI Animal Welfare and Disease Control Seminar, organized at September 23, 2015 in Celle, Germany
The document discusses the safety and supply of plasma-derived hemophilia products. It outlines how fractionation advances in the 1960s-1970s enabled treatment to free hemophiliacs. Both plasma-derived and recombinant products are important, with no single supply sufficient. Industry standards have reduced pathogen risks through donor selection, testing, and viral clearance steps. Emerging pathogens like West Nile virus require ongoing vigilance. While risks are low, vCJD transmission through plasma products remains a concern addressed through geographic deferrals and manufacturing clearance. Increasing global product demand challenges adequate supply for all patients.

This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.

Instead of slowing down the spreading of the virus, the outbreaks continue to reoccur and have caused death and destruction in 15 USA states, killing almost 50 million birds on mote than 220infected commercial poultry farms, all within a very small time frame.
The question is whether the priority of the response strategy should be on neutralizing the transmission routes instead of on stamping out infections after they occur. All indicators currently point out into the direction that the industry should prioritize on environmental drivers: the connection between outbreaks and wild ducks; wind-mediated transmission; pre-contact probability; on-farm bio security; transmission via rodents etc.
Once the contribution of each transmission route has been determined, a revolutionary new response strategy can be developed based on the principle of neutralizing transmission routes. Neutralizing risks means that fully new techniques need to be developed, based on culling the animals without human – to – animal contact; integrating detergent application into the culling operations; combining culling & disposal into one activity.
This new response strategy will be the main subject of the FLI Animal Welfare and Disease Control Seminar, organized at September 23, 2015 in Celle, Germany
The document discusses the safety and supply of plasma-derived hemophilia products. It outlines how fractionation advances in the 1960s-1970s enabled treatment to free hemophiliacs. Both plasma-derived and recombinant products are important, with no single supply sufficient. Industry standards have reduced pathogen risks through donor selection, testing, and viral clearance steps. Emerging pathogens like West Nile virus require ongoing vigilance. While risks are low, vCJD transmission through plasma products remains a concern addressed through geographic deferrals and manufacturing clearance. Increasing global product demand challenges adequate supply for all patients.

This document discusses a conference presentation on the development of vaccines for foot-and-mouth disease (FMD). FMD is a highly contagious disease of cloven-hooved animals that causes significant economic losses. The presentation covers the importance of animal agriculture, FMD virology and pathogenesis, the costs of FMD outbreaks, efforts to eradicate the disease, and existing and next-generation FMD vaccines. The ideal FMD vaccine would provide rapid, long-lasting protection with a single dose while avoiding the risks associated with existing vaccines that require growing the live virus.

Milan J. Anadkat, MD, and Dale V. Reisner discuss generalized pustular psoriasis in this CME activity titled "Supporting Patient-Centered Care in Generalized Pustular Psoriasis: Communications Strategies to Improve Shared Decision-Making." For the full presentation, please visit us at www.peervoice.com/HUM870.
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.

GASTROINTESTINAL INFECTIONS AND GASTRITIS
Osvaldo Bernardo Muchanga
Gastrointestinal Infections
GASTROINTESTINAL INFECTIONS result from the ingestion of pathogens that cause infections at the level of this tract, generally being transmitted by food, water and hands contaminated by microorganisms such as E. coli, Salmonella, Shigella, Vibrio cholerae, Campylobacter, Staphylococcus, Rotavirus among others that are generally contained in feces, thus configuring a FECAL-ORAL type of transmission.
Among the factors that lead to the occurrence of gastrointestinal infections are the hygienic and sanitary deficiencies that characterize our markets and other places where raw or cooked food is sold, poor environmental sanitation in communities, deficiencies in water treatment (or in the process of its plumbing), risky hygienic-sanitary habits (not washing hands after major and/or minor needs), among others.
These are generally consequences (signs and symptoms) resulting from gastrointestinal infections: diarrhea, vomiting, fever and malaise, among others.
The treatment consists of replacing lost liquids and electrolytes (drinking drinking water and other recommended liquids, including consumption of juicy fruits such as papayas, apples, pears, among others that contain water in their composition).
To prevent this, it is necessary to promote health education, improve the hygienic-sanitary conditions of markets and communities in general as a way of promoting, preserving and prolonging PUBLIC HEALTH.
Gastritis and Gastric Health
Gastric Health is one of the most relevant concerns in human health, with gastrointestinal infections being among the main illnesses that affect humans.
Among gastric problems, we have GASTRITIS AND GASTRIC ULCERS as the main public health problems. Gastritis and gastric ulcers normally result from inflammation and corrosion of the walls of the stomach (gastric mucosa) and are generally associated (caused) by the bacterium Helicobacter pylor, which, according to the literature, this bacterium settles on these walls (of the stomach) and starts to release urease that ends up altering the normal pH of the stomach (acid), which leads to inflammation and corrosion of the mucous membranes and consequent gastritis or ulcers, respectively.
In addition to bacterial infections, gastritis and gastric ulcers are associated with several factors, with emphasis on prolonged fasting, chemical substances including drugs, alcohol, foods with strong seasonings including chilli, which ends up causing inflammation of the stomach walls and/or corrosion. of the same, resulting in the appearance of wounds and consequent gastritis or ulcers, respectively.
Among patients with gastritis and/or ulcers, one of the dilemmas is associated with the foods to consume in order to minimize the sensation of pain and discomfort.

Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) CosmeticsMuskanShingari
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.
Selective alpha1 blockers are Prazosin, Terazosin, Doxazosin, Tamsulosin and Silodosin majorly used to treat BPH, also hypertension, PTSD, Raynaud's phenomenon, CHF
Fexofenadine is sold under the brand name Allegra.
It is a selective peripheral H1 blocker. It is classified as a second-generation antihistamine because it is less able to pass the blood–brain barrier and causes lesser sedation, as compared to first-generation antihistamines.
It is on the World Health Organization's List of Essential Medicines. Fexofenadine has been manufactured in generic form since 2011.

Guinat, C., et al. "Inferring within‐herd transmission parameters for African swine fever virus using mortality
data from outbreaks in the Russian Federation." Transboundary and emerging diseases 65.2 (2018): e264-
e271.
Field (inside farm): Infectivity (transmission rates per day) is 0.7–2.2 (R0 ~6)
Experiments (inside farm): Infectivity (transmission rates per day) is 0.3–0.9 (R0 ~2)
Field (between farm): estimation of the depopulation value to get R0 is 3
Experiments (WB, inside farm): C-index ~0.08 (R0 ~0.9)
Field (WB): C-index ~0.12 (R0 ~1.4)
C-index (Atack rate) is percentage of animals which get infected after contact with
an infectious agent or probability that an animal picks up an infection after contact
with a pathogen

around 65 notifications observed only for border counties) is a characteristic
property of an externally stimulated system, thus it suggests quasi-periodic
import of infections through Polish Eastern border.

22. We are comparing standard directly generalized linear regression with machine learning
in boosted tree classification and indirectly phenomenological SIR - type model.
We found that predictability of epizootic state (defined binary) one
period in advance on the border between disease free and in
affected regions reaches over 95% sensitivity and specificity with
XBoost, which outperformed other methods. Machine learning
seems to be the best predictor in a neighborhood of an already
affected area.
WB pigs
23. Model – spatial - based propagation
We run set of simulations for selected subspace of simulation
parameters:
a- swine amount significance,
b- wild boars significance,
c- pork production chain significance.
d- human mobility significance
Where:
i, j – poviats; P – normalized amount of pigs; F – coverage of
forests; pij -probability of infection from a neighbor; gij -
probability of infection from a whole networks; dij -angular
distance between centroids of poviats (counties).
25. Scenario testing 2018
„Ideal” barrier for WB:
- fence on the Eastern Border
- blocking corridors on A1 motorway
Objectives:
- Arrival time to swine district (fencing, A1)
- Border vs Interior dynamics
26. Infectious paths
A1:There is an important difference in the arrival time to swine district (most likely to be
affected in 39 months – on average half a year barrier).
Fence: There is only a small difference in the arrival time to swine hot spot
district (most likely to be affected in 34.2 months – on average less than one
month barrier)
Base line (33 arrival time) months since
December 2018
vs
Border Fencing or corridors blocking on A1
28. ASF in Poland - Summary
Conclusions
• Fencing border – a small difference in arrival time to swine district;
• Corriors blocking on N-S motorway – moderate delay in propagation;
• Seasonality, Memory, Clustering – significant difference between
interior and border (properties of externally stimulated system), so
importing cases is possible
• Maching Learning + Phenomenological Model (good prediction
power)
